EXECUTIVE SUMMARY
Psychotropic medication use has increased markedly in children
and adolescents with psychiatric disorders. Children in foster care
are particularly vulnerable due to biological, psychological, and
social risk factors that may lead to emotional and/or behavioral
problems. Previous studies have illustrated many of the adverse
effects of inappropriate utilization of psychotropic medications in
children, such as poorer health status, higher obesity and diabetes
prevalence, and minimal control of behavioral problems. This
report seeks to expand the growing body of literature on
psychotropic medication use in children enrolled in South Carolina
Medicaid program, particularly for children in the foster care
system. Evidence‐based recommendations for providing quality
psychiatric care to children enrolled in Medicaid are presented.
Information for the report was drawn from South Carolina Medicaid claims housed at the Institute for
Families in Society (University of South Carolina). Children with at least one psychotropic medication
prescription in calendar year (CY) 2011 were included in the de‐identified data for a retrospective
analysis from January 1, 2009, through December 31, 2011. The status of the children in the study was
classified as adoption, ISCEDC (Interagency System of Care for Emotionally Disturbed Children), MCC
(Medically Complex Children), regular foster care, and non‐foster care. Race/ethnicity was defined as
non‐Hispanic White (hereafter “White”), non‐Hispanic African American/Black (hereafter “African
American”), and “Other” which included all other children including those identified as Hispanic, Asian
and Pacific Islander (API), American Indian and Alaska Native (AI/AN), and multiracial. Descriptive
statistics and comparisons are provided for the following groups: 1) children in regular foster care vs.
children in non‐foster care, 2) children in ISCEDC vs. children in regular foster care, and 3) children in
adoption category vs. children in regular foster care.

Key findings of the report include:
General Profile
Children enrolled in SC Medicaid who received at least one psychotropic medication prescription
in CY 2011 were predominantly males (60%) and had an average age of 12 years.
Nearly a third of the sample lived in rural areas and less than a fifth lived in areas with high
social deprivation.
Based on the clinical risk group (CRG) system classification, all children in MCC category were
classified under severe‐to‐catastrophic CRG followed by nearly 90% of ISCEDC children, 63% of
regular foster care children, 59% of adopted children, and 54% of non‐foster care children.
Children in ISCEDC category were significantly more likely, but children in non‐foster (53.81%)
and adoption (58.84%) categories were significantly less likely to be categorized under severe‐
to‐catastrophic CRG compared to children regular foster care category (63.01%).
Nearly one in five children (17%) did not have a listed psychiatric diagnosis in their claims data.
ADHD was the most common psychiatric diagnosis irrespective of the child’s foster care status.
Children in ISCEDC category (99.35%) were significantly more likely, but children in non‐foster
(82.37%) and adoption (89.92%) categories were significantly less likely to have listed psychiatric
diagnoses compared to their regular foster care peers (93.34%).
Prescription Patterns
Receipt of Psychotropic Prescriptions
The top three psychotropic drug classes prescribed included ADHD medications (73.18%),
antidepressants (23.72%), and anticonvulsants (14.49%). Barbiturate sedatives and mood
stabilizers were the least prescribed medications.
More than three quarters of the children received medications from a single psychotropic drug
class (mono‐class treatment).
Irrespective of the child’s foster care status, the top two psychotropic drug class combinations
were ADHD medications and antidepressants followed by ADHD medications and antipsychotics.
Children in regular foster care category (31.86%) were significantly more likely than those in
non‐foster category (22.66%) and significantly less likely than those in ISCEDC category (63.10%)
to receive multi‐class (two or more drug classes) psychotropic treatment.
iii
Receipt of Antipsychotic Prescriptions
Males were significantly more likely to receive antipsychotic prescriptions compared to females
across all status categories.
All children in foster care category and nearly all children in ISCEDC category who received
antipsychotics had listed psychiatric diagnoses. However, nearly 4% of children in adoption and
5% of children in non‐foster category did not have any listed psychiatric diagnoses despite
receiving antipsychotic prescriptions.
The majority of children who received antipsychotics also received medications from one or
more other psychotropic drug classes (87.83%). Of the total children on antipsychotics, nearly
44% received medications from three or more drug classes.
When compared by status, children in ISCEDC category were significantly more likely than
children in regular foster category to receive medications from three or more drug classes.
Among children who received antipsychotic medications, those with second‐generation
antipsychotic prescriptions were more likely to be adherent than those with first‐generation
antipsychotic prescriptions.
Receipt of Psychiatric Services
Of the total sample, 36.26% received psychiatric services as adjunct therapy to psychotropic
medication(s).
The proportion of children receiving psychiatric services was highest among children in ISCEDC
category and lowest among those in MCC category.
Children in regular foster care category (71%) were significantly more likely than children in non‐
foster category (34.44%) and those in adoption category (46.18%), but significantly less likely
than children in ISCEDC category (91.67%) to receive psychiatric services.
Among those who received antipsychotic prescriptions, overall more than two thirds of children
(68.09%) received psychiatric services. Children in regular foster care were significantly more
likely to receive psychiatric services compared to those in non‐foster and adoption categories.
iv
Recommendations and Future Steps
The study findings suggest that there are several opportunities to improve the oversight and
management of psychotropic medications prescribed to children in Medicaid proactively and in a holistic
manner. Based on the study findings, this report offers key recommendations using the patient‐
centered medical home (PCMH) framework, which is designed to orient strategies to refine and improve
the organization of health care delivery. These recommendations include:
Psychiatric diagnosis must be documented by applying specific diagnostic criteria using screening
and evaluation protocols for children, youth, and adolescents enrolled in SC Medicaid irrespective of
their foster care status.
A comprehensive mental health treatment plan that includes psychiatric services as alternative or
adjunct to pharmacological treatment and provisions of second opinion by a qualified psychiatrist
when appropriate should be developed by a psychiatrist in consultation with the primary care
provider.
Regular monitoring of psychotropic medication prescription patterns/use should be conducted on a
semi‐annual basis.
Information exchange and care coordination among providers, patients, and caregivers should be
considered critical elements of overall patient management plan.
Training and continuing education programs for providers should include mandatory mental health
components and updates related to changes in clinical practice guidelines related to psychotropic
medication use among children and adolescents.
Establish a psychotropic medication oversight advisory committee consisting of a wide range of
stakeholders to oversee psychotropic medication prescriptions for children and adolescents enrolled
in Medicaid with annual reports to state agencies.
Future studies should continue research on trends in psychotropic medication prescription patterns and
undesirable health impacts of these medications, particularly among high risk children who receive
multiple psychotropic medications concurrently.

GLOSSARY Below is a glossary of terms and acronyms associated with psychotropic prescriptions used extensively in this report. See the technical notes for detailed information on study variables of interest.
Term/Acronym Definition
Adherence The extent to which patients take medications as prescribed by their health care providers. The term “adherence” is generally preferred by providers due to the passive patient behavior referenced with the “compliance” term. Both terms are imperfect descriptions of medication‐taking behavior and not actual observation of consumption of prescribed medications.
Adoption Adoption is the practice in which an adult assumes the role of parent for a child who is not the adult's biological offspring in a formal legal arrangement. Adoption is a subcategory of foster care in this report. Children and youth with adoptive parents are no longer in foster care services. However, some adoptive parents receive financial assistance to help sustain the adoption given the special needs and/or circumstances of the children adopted. Adoption subsidies are funded through SC Medicaid, thus these children are continued as part of the foster care database for administrative purposes. Although, no longer in foster care, these children were considered a sub‐category of foster care for this study.
Antipsychotics These are psychotropic drugs used to treat psychotic disorders. They are usually classified into two categories: first generation (typical) antipsychotics and second generation (atypical) antipsychotics.
Compliance The extent to which patients take medications as prescribed by their health care providers. The term “adherence” is generally preferred by providers due to the passive patient behavior referenced with the “compliance” term. Both terms are imperfect descriptions of medication‐taking behavior and not actual observation of consumption of prescribed medications.
CRG Clinical Risk Groups (CRGs) are a clinical model in which each individual is assigned to a single mutually exclusive risk group which relates the historical clinical and demographic characteristics of the individual to the amount and type of health care resources that individual will consume in the future. The categories are ranked in order of severity.
CPT Code Current Procedural Terminology (CPT) codes describe medical, surgical, and diagnostic services offered to the patients. The list of CPT codes is published by the American Medical Association.
Foster Care System in which a minor who has been made a ward is placed in an institution, group home, or private home of a state certified caregiver. The placement of the child is usually arranged through the government or a social service agency. Several subcategories of foster care are in this report: adoption, ISCEDC, MCC, and regular foster care.

Medication Possession Ratio is a medication utilization metric that measures patient’s adherence or compliance and is defined as the sum of a medication’s days of supply divided by the total number of days in a time interval.
Mono‐class Therapy
Receipt of medication from a single psychotropic class (see Psychotropic Drug Class).
Multi‐class Therapy
Receipt of medications from two or more psychotropic classes.
PSADI The Palmetto Social Deprivation Index (PSADI) is a scale of indicators of social deprivation developed for South Carolina based on selected Census criteria. Similar to the Townsend Index for Social Deprivation.

Psychiatric Diagnoses
Clinical diagnosis of mental health condition based on reported ICD‐9 diagnostic codes.
Psychiatric Services
Adjunct services (such as psychotherapy, counseling, or family therapy) offered to persons with psychiatric conditions.
Psychotropic Drug Class
Psychiatric medications used to treat mental disorders. Sometimes called psychotherapeutic medications. Eight classes are referenced in this report: attention deficit/hyperactivity disorder (ADHD) medications, antianxiety medications, anticonvulsants, antidepressants, antipsychotics, barbiturate sedatives, mood stabilizers, and non‐barbiturate sedatives.

ORGANIZATION OF THE REPORT
This report is organized into four chapters. Chapter 1 is an overview of background information about
the use of psychotropic medications among children, the rationale for and the purpose of the study,
and research questions. Chapter 2 focuses on South Carolina Medicaid children who received
prescriptions for psychotropic medication(s) in calendar year 2011. In addition to describing their
demographic characteristics, it also describes their health status based on CRG classification, reported
psychiatric diagnosis, the patterns of psychotropic prescriptions, and receipt of psychiatric services, if
any. This chapter includes four sections. The first section describes overall characteristics of children
enrolled in SC Medicaid who received at least one prescription of psychotropic medication in calendar
year (CY) 2011.
The remaining three sections describe comparisons between 1) regular foster care children and non‐
foster care children, 2) children under ISCEDC category and regular foster care children, and 3) children
under adoption category and regular foster care children. Chapter 3 focuses exclusively on children
who received antipsychotic medication prescriptions. This chapter also includes similar comparisons
(regular foster vs. non‐foster, ISCEDC vs. regular foster, and adoption vs. regular foster) as in Chapter 2.
In addition to demographic characteristics, CRG status, psychiatric diagnosis, and adjunct psychiatric
services, this chapter also describes compliance to antipsychotic medications. Chapter 4 offers
discussion on the study findings and policy recommendations. Additionally, it lists potential limitations
of the study. A detailed description of methods (study sample, variables of interest and their
definitions, statistical analyses, etc.) is outlined in the technical notes. Detailed tables of the study
findings are included in the appendices.

CHAPTER 1: INTRODUCTION Background
Over the past two decades, the use of psychotropic medications for children and adolescents with
psychiatric disorders has increased considerably, primarily due to better understanding of childhood
psychiatric disorders and evidence base supporting the use of such medications.1, 2 Although there is
substantial evidence supporting use of a single psychotropic medication, not enough evidence is available
regarding use of psychotropic medication combinations. These combinations are often used to treat
complex comorbid conditions, enhance outcome for treatment refractory conditions, or manage side
effects of the primary medications.1 Further, medical providers often use psychotropic medications “off‐
label” or inconsistent with product labeling to suit the child’s needs.1 In many instances, the prescriber is a
non‐psychiatric physician.2, 3
Concomitant use of psychotropic medications or poly‐pharmacy is common among children, including
those in foster care, despite lack of adequate research on safety and efficacy of multi‐class psychotropic
regimens.3 National trends in psychotropic poly‐pharmacy among children and adolescents indicated that
there was a significant increase in the proportion of children who received two or more psychotropic drugs
from different drug classes in an outpatient setting between 1996 and 2007 and that a majority of
psychotropic visits were to non‐psychiatric physicians.4 Researchers from Florida examined prevalence of
poly‐pharmacy of antipsychotic medications among children and adolescents enrolled in Florida’s Medicaid
fee‐for‐service program using Medicaid claims data and found that 7% of children and 8% of adolescents
received poly‐pharmacy.5
As previously stated, off–label use of psychotropic medications is also common among youth. For example,
a retrospective cohort study using data from children and adolescents enrolled in Tennessee’s managed
care program for Medicaid and uninsured found that the proportion of children using antipsychotic
medications nearly doubled between 1996 and 2001 and that there was a significant increase in the use of
antipsychotic medications for attention‐deficit‐hyperactivity disorder (ADHD), conduct disorder, and
affective disorder.6 Analysis from a nationally representative sample of children revealed that overall
frequency of antipsychotic prescription increased from 8.6 per 1,000 US children in 1995‐96 to 39.4 per
1,000 US children in 2001‐02 and that more than half of the prescriptions were for behavioral or affective
disorders.2
Many children in foster care have biological, psychological, and social risk factors that lead to emotional
and/or behavioral problems.7, 8 Foster care children with health care needs often experience fragmented
medical and psychiatric care as a result of multiple placements and lack of resources for assessing and
treating them.2 These children are often prescribed psychotropic medications at higher rates compared to
their non‐foster peers enrolled in Medicaid and those with private insurance.9, 10 In an examination of
antipsychotic medication use among Medicaid‐enrolled foster care children in 48 states between 2002 and
2007, rates were stable or decreased in only 3 states while increases ranged from 6.4% to 71.9% in the
remaining states.11 The rate of second generation antipsychotic use in in South Carolina increased 41.3%
11
between 2002 and 2007.11 Further, poly‐pharmacy and “off‐label” use of psychotropic medication are
common in foster care children. In a study comparing concomitant antipsychotic use among Medicaid‐
enrolled youth in foster care with disabled or low‐income Medicaid youth, researchers found that youths in
foster care were more likely to receive antipsychotics concomitantly and for longer duration of time
despite lack of supporting evidence.12 In general, it is recommended that pharmacotherapy should be
combined with another evidence‐based treatment such as psychotherapy, family skills training, or behavior
management among children with a mental disorder.13
Although the use of psychotropic medications has been shown to effectively treat mental health
conditions, there are concerns about efficacy of poly‐pharmacy and its potential long term impact on
health, particularly among children. Limited information is available regarding prescription patterns of
psychotropic medications and the use of adjunct therapy among children enrolled in South Carolina
Medicaid. Whether foster care children have been disproportionately prescribed psychotropic medications
compared to non‐foster children in Medicaid, particularly in the absence of adjunct therapy, remains to be
determined. If so, current guidelines and recommendations for initiating and monitoring psychotropic
prescriptions will need to be revised to prevent non‐indicated and inappropriate prescriptions of
psychotropic medications.
Purpose of the Report
The purpose of this study was to describe psychotropic medication prescription patterns among South
Carolina Medicaid‐enrolled children who have received psychotropic medication(s) in calendar year 2011
with special attention given to those children receiving foster care services. Additionally, the study
compared these prescription patterns by child status, age group, gender, race, and residence in areas with
social deprivation. Further, the analyses focused on children who received prescription of antipsychotic
medication(s) since there is a growing concern over increasing trend of using antipsychotic medications
among children.
Research Questions
The following research questions were considered.
1. What is the profile of children enrolled under SC Medicaid who received at least one psychotropic prescription in CY 2011?
2. Among children enrolled under SC Medicaid who received psychotropic medications in CY 2011, what proportion of children in each group (non‐foster, adoption, ISCEDC, MCC, and regular foster care) received medications from the following drug classes: ADHD medications, antianxiety medications, anticonvulsants, antidepressants, antipsychotics, barbiturate sedatives, non‐barbiturate sedatives, and mood stabilizers?
3. What are the clinical risk group categories of children receiving psychotropic medication(s)?
4. What psychiatric diagnoses are assigned to children receiving psychotropic medications?
12
5. What proportion of children in each group received multi‐class treatment (defined as receipt of psychotropic medications from two or more drug classes)?
6. What proportion of children in each group received additional psychiatric services as adjunct to the psychotropic medications?
7. Are there any group differences in socio‐demographic characteristics and receipts of psychotropic medication classes, psychiatric diagnoses, and psychiatric services by child status?
8. What proportion of children in each group who received antipsychotic medications have associated ICD‐9 diagnoses related to hyperglycemia, diabetes, weight gain, metabolic syndrome, pancreatitis, neurological/movement disorders, and cardiovascular complications?

Section I describes general profile of all children in the study sample;
Section II describes comparisons between regular foster care children
(not including those in adoption, ISCEDC, and MCC categories) and
non‐foster care children;
Section III describes comparisons between children in ISCEDC category
and regular foster care category; and
Section IV describes comparisons between children in adoption
category and regular foster care category.
CHAPTER 2: PSYCHOTROPIC PRESCRIPTION CLAIMS
As mentioned earlier, psychotropic medication use has increased markedly in children and adolescents;
however, there is still a lack of consensus on appropriate use for certain classes of drugs. In this chapter,
the profile of children enrolled in South Carolina Medicaid with at least one psychotropic medication
prescription in the CY 2011 is presented with information about their clinical status, demographic
characteristics, and use of psychiatric services.
Although, children under adoption, ISCEDC, and MCC categories are often grouped together with regular
foster care children under the foster care category, in our opinion, each of these subcategories has unique
features and should not be considered as a single group. We acknowledge that children once adopted
cannot be considered as foster care children since now they have legal parents. In that sense, they should
not be considered as a part of foster care children. Additionally, children in ISCEDC category have
documented needs of mental health services and are emotionally unstable. Their mental health service
utilization patterns including prescriptions of psychotropic medications and psychiatric services may be
higher compared to other children in foster care category. Higher mental health needs and mental health
service utilization among children under the ISCEDC category may influence results if they are considered
together with other foster care children. Therefore, we examined psychotropic prescription patterns and
mental health service utilization among these children based on their foster care status. In addition to the
descriptive statistics, we conducted chi‐square tests to compare children in different status categories. It
should be noted that given a very small sample size in MCC category (n=50), it was not included in further
analysis. This chapter includes four sections.

Section I: Characteristics of Children Receiving Prescriptions of Psychotropic Medications
General Profile
Table 2.1 describes the profile of SC Medicaid children who received at least one psychotropic prescription
in 2011. Highlights of the table are indicated below.
Demographic characteristics:
Males made up more than 60% of the total sample. The average age of
children in the sample was approximately 12 years with approximately 3%
of the children younger than 5 years of age. The largest proportion was in
the age group of 10‐14 years (37.47%) followed by age groups 5‐9 years
(29.91%) and 15‐17 years (17.84%). Slightly more than half of the sample
was White (52.78%). Approximately a third of SC Medicaid children
receiving psychotropic medications lived in rural areas (32.66%). When
examined by social deprivation indicator, overall 17.81% of the sample
lived in high deprivation areas.
Foster care status:
Children not in foster care were the overwhelming majority of Medicaid
enrollees in the sample (93.32%). Foster care status included four
categories, regular foster care, ISCEDC, MCC, and adoption. Out of 4,202
foster care children, the majority were classified under adoption category
(53.59%) followed by regular foster care (23.23%) and ISCEDC (21.99%).
Very few Medicaid enrollees in foster care were classified as medically
complex children (1.19%).
Clinical characteristics:
The majority of SC Medicaid children who received psychotropic
prescriptions in CY 2011 were categorized under severe to catastrophic
clinical risk group (CRG) categories (54.7%). Overall, nearly 83% of children
who received psychotropic medication prescriptions also had a reported
psychiatric diagnosis. Only about 36% of children received psychiatric
services in addition to the pharmacologic treatment.

Clinical Risk Groups by Child Status
The clinical risk group (CRG) system classifies individuals into mutually exclusive categories and assigns each
person with a chronic health condition to a severity level based on enrollment, claims, or other encounter
level data. In the total sample,
4,546 children (7.23%) were
classified as healthy (CRG 1).
When considered by status,
as expected all children who
were classified as MCC had
severe‐to‐catastrophic CRG
(Figure 2.1) followed by
children with emotional
disturbances (89.94%). The
lowest proportion of children
classified as having severe‐to‐
catastrophic CRG was found
among non‐foster children
(53.81%).
Psychotropic Prescription Patterns
Eight classes of psychotropic medications are included in the profile of children enrolled in South Carolina
Medicaid. The psychotropic medication classes are ADHD medications, antianxiety medications,
anticonvulsants, antidepressants, antipsychotics, barbiturate sedatives, mood stabilizers, and non‐
barbiturate sedatives. All psychotropic medication use in children and adolescents require careful
monitoring by clinicians; however, the potential health complications associated with antipsychotic
medications in children are particularly grave. As such, Chapter 3 deals exclusively with children who
received antipsychotic prescriptions.
Table 2.2 describes the psychotropic prescription patterns among the study sample. The top three
psychotropic drug classes prescribed included ADHD medications (73.18%) followed by antidepressants
(23.72%) and anticonvulsants (14.49%). Barbiturate sedatives and mood stabilizers were the least
prescribed psychotropic medications during the study period. More than three quarters of children (76.3%)
received psychotropic medications from only one drug class (Mono‐class treatment).

ADHD Medications
Overall, 46,000 SC Medicaid
children (73.18% of the total
sample) received prescriptions of
ADHD medications in CY 2011.
Please refer to Appendix B2 for
ADHD medication list. Figure 2.2
indicates the proportion of children
receiving ADHD prescriptions by
sex and status. Males were more
likely to receive ADHD medications
compared to females irrespective
of their status. Among children
who received ADHD prescriptions,
the proportion of males was higher
among non‐foster category
(70.21%) compared to other
categories. Proportion of females
receiving ADHD medications in any
category was highest in the adoption category (38.98%).

Other findings among children receiving ADHD medication prescriptions (See Table A1 in Appendix A)
included:
The proportion of children receiving ADHD medications was highest among
children in the age group of 10‐14 years (43.33%) followed by the age group
5‐9 years (35.94%).
More than half of the children receiving ADHD medications were Whites.
Approximately half of the children were categorized as severe‐to‐
catastrophic CRG.
The majority lived in areas with low to moderate social deprivation
(82.36%).
The majority had a psychiatric diagnosis listed in the claims data (94.07%).
Less than 40% had received psychiatric services in addition to the
pharmacologic treatment.
Children in regular foster care were significantly more likely than children in
non‐foster care and adoption categories (all p<.0001), but less likely than
those in ISCEDC category (p<.001 and p<.0001 respectively) to have listed
psychiatric diagnoses and to receive psychiatric services.
Nearly one in four children (23.97%) received multi‐class treatment. Regular
foster care children were significantly more likely than non‐foster care
children, but less likely than ISCEDC children to receive multi‐class
treatment (both p<.0001).
20
Antidepressant Medications
Less than a quarter of the sample
received antidepressant
medications (n=14,909). Refer to
Appendix B3 for the list of
antidepressant medications. Figure
2.3 indicates distribution of children
receiving antidepressant
medications by sex and status. In
general, females were more likely
to receive antidepressants
compared to males except in
adoption category. However, these
differences were not statistically
significant.

21
Anticonvulsant Medications
Of the SC Medicaid children who received psychotropic medication prescriptions in CY 2011, 9,107 children
(14.49%) received anticonvulsants (for the list of anticonvulsants, refer to Appendix B4). Of these 8,449
(92.77%) were non‐foster children. Irrespective of the status, males were more likely to receive
anticonvulsants compared to females (Figure 2.4). However, there were no statistically significant
differences in receipt of anticonvulsants by gender.
Other findings among children receiving anticonvulsants are reported in Table A4 in Appendix A. Some
highlights included:
The most common age groups receiving anticonvulsants included 10‐14 years (28.66%) followed by
15‐17 years (22.16%), and 18‐21 years (21.34%).
African Americans and other minorities made up more than half of the children receiving
anticonvulsants.
Nearly 86% of children receiving antianxiety medications were categorized as severe‐to‐
catastrophic CRG.
The majority lived in areas with low‐moderate social deprivation (81.39%).
Approximately 60% had a listed psychiatric diagnosis.
Approximately 36% received psychiatric services in addition to the pharmacologic treatment.
Children in regular foster care were significantly more likely than children in non‐foster care
category, but less likely than those in ISCEDC category to have listed psychiatric diagnoses (both
p<.0001).

Nearly 58% of children who received anticonvulsants received multi‐class treatment. Regular foster
care children were significantly more likely than non‐foster care children (p=.0002), but significantly
less likely than ISCEDC children (p<.0001) to receive multi‐class treatment.
Antianxiety Medications
Overall, 4,190 SC Medicaid
children (6.67% of the total
sample) received
prescriptions of antianxiety
medications in CY 2011.
Please refer to Appendix B5
for antianxiety medication
list. As shown in Figure 2.5,
females were more likely to
receive antianxiety
medications than their male
counterparts in non‐foster
care and adoption
categories.
Other findings among children receiving antianxiety prescriptions (See Table A4 in Appendix A) included:
The most common age groups receiving antianxiety medications were 18‐21 years (30.91%)
followed by 15‐17 years (23.96%).
Slightly more than half were Whites (51.60%) and were categorized as severe‐to‐catastrophic CRG
(54.18%).
The majority lived in areas with low to moderate social deprivation (80.19%).
Slightly more than half (51.31%) of the children receiving antianxiety medications had a psychiatric
diagnosis listed in the claims data.
Less than a quarter received psychiatric services in addition to the pharmacologic treatment.
Significantly more children in the “all foster care” category (please note that due to smaller sample
sizes in individual foster care categories, children in adoption, ISCEDC, MCC, and regular foster
were grouped together as an all foster care category) were significantly more likely to have listed
psychiatric diagnoses and receive psychiatric services compared to non‐foster children receiving
antianxiety medications (both p<.0001).

Barbiturate Sedative, Mood Stabilizer, and Non‐barbiturate Sedative Medications
Smaller proportions of children receiving
psychotropic medications received
barbiturate sedatives (n=249), mood
stabilizers (n=302), and non‐barbiturate
sedatives (n=1,423). Due to smaller sample
sizes in each status category by each of
these psychotropic drug classes, children
in regular foster care, adoption, ISCEDC,
and MCC categories were grouped
together in an all foster care category. The
distribution by gender and status (all
foster care vs. non‐foster) are reported for
each of these three classes.
Figure 2.6 indicates the proportion of
children receiving barbiturate sedatives by
sex and status. Overall, 249 children
(0.40% of the total sample) received
barbiturate sedatives. Of these children,
the majority were non‐foster children.
Other findings are reported in Table A5 in
Appendix A. No children in ISCEDC
category received barbiturate sedatives.
Reported p values are not reliable due to
small cell sizes.
Out of 302 children who received mood
stabilizers, the majority (83.44%) were
non‐foster children. Males were more
likely to receive mood stabilizers
compared to females among non‐foster
children (Figure 2.7). However, these
differences were not statistically

Psychiatric Diagnoses
Eight categories of psychiatric diagnoses were examined using ICD‐9 codes (Please refer to the technical
notes for details). These included ADHD, adjustment disorders, anxiety disorders, disruptive behavior
disorders (conduct disorder and oppositional defiant disorder), mood disorders (bipolar disorder,
depressive disorder not classified elsewhere, and dysthymic disorder), pervasive developmental disorders
(PDD), psychotic disorders (schizophrenia, delusional disorders, & other non‐organic psychoses), and
substance abuse disorders (alcohol dependence syndrome, drug dependence, and non‐dependent drug
abuse). ADHD was the most common psychiatric diagnosis among children irrespective of the status. Table
2.4 indicates reported psychiatric diagnoses among the sample.

Section II: Comparisons Between Regular Foster Care and Non‐Foster Care Children
This section describes the psychotropic prescription patterns, reported psychiatric diagnoses, and receipt
of psychiatric services in addition to the pharmacologic treatment among regular foster care children and
non‐foster care children.
The characteristics of children in regular foster care and non‐foster care categories who received at least
one psychotropic prescription in CY 2011 are shown in Table 2.5.

The highlights of Table 2.5 include:
Although males made up the majority irrespective of the status, the proportion of males was
lower in the regular foster care category compared to that in the non‐foster category.
The proportion of Whites was slightly higher among non‐foster children (53.19%) compared to
the regular foster care category (50.0%).
Regular foster care children were significantly more likely to be categorized under severe‐to‐
catastrophic CRG compared to those from the non‐foster category (63.01% vs. 53.81%
respectively).
Regular foster care children were significantly more likely to have a listed psychiatric diagnosis
compared to non‐foster children (93.34% vs. 82.37% respectively).
Regular foster care children were significantly more likely to receive psychiatric services in
addition to the pharmacologic treatment compared to their non‐foster peers (71.0% vs. 34.44%
respectively).
Psychotropic Prescription Patterns
The majority of children received a mono‐class treatment (receipt of psychotropic medication from a single
psychotropic drug class) irrespective of their status (68.14% of regular foster care and 77.34% of non‐foster
care children). Please note that seven children who received Provigil‐Nuvigil were not included in these
analyses due to extremely small sample size. Proportions of children in regular foster care and non‐foster
care categories receiving specific psychotropic drug class are shown in Table 2.6 below.

Among those who received multi‐class treatment, significantly more children in regular foster care received
medications from more than one psychotropic drug class compared to children in the non‐foster care
category (Table 2.7). The proportion of children in each category decreased as the number of psychotropic
drug classes increased. Significantly more foster care children received medications from three or more
psychotropic drug classes compared to their non‐foster care peers. However, when the cut‐off point was
raised to four drug classes or more, no statistical difference was found among children in the two
categories (Table 2.7).

Overall, non‐foster children were significantly
more likely to have no reported psychiatric
diagnosis (17.62%) compared to regular foster
care children (6.66%). Approximately 20% of non‐
foster children receiving mono‐class treatment
did not have a listed psychiatric diagnosis
compared to 7.67% of regular foster care children
on mono‐class treatment (Figure 2.10). Among
children who received multi‐class treatment,
9.43% of non‐foster and 4.5% of regular foster care children did not have any listed psychiatric
diagnosis.

Psychiatric Diagnoses
Approximately 93% of children in regular foster care and 82% of non‐foster children had listed psychiatric
diagnoses (Table 2.5). With an exception of pervasive developmental disorders (PDD) and psychotic
disorders, regular foster care children were significantly more likely to have specific psychiatric diagnoses
compared to non‐foster care children (Table 2.8). ADHD was the most common psychiatric diagnosis
among children irrespective of their foster care status. This was followed by adjustment disorders (44.47%),
disruptive behavior disorders (30.33%), and mood disorders (28.38%) among regular foster care children.
Among non‐foster care children, ADHD was followed by disruptive behavior disorders (15.86%), mood
disorders (14.74%), and adjustment disorders (9.62%). Table 2.8 indicates reported psychiatric diagnoses

Receipt of Psychiatric Services
Figure 2.11 displays the comparison of
regular foster care and non‐foster care
children who received psychiatric
services as adjunct to the
pharmacological treatment during the
study period. Receipt of psychiatric
services was determined by CPT codes
listed in the claims data (see technical
notes for specific CPT codes). There
was a significant difference in receipt
of psychiatric services among regular
foster care and non‐foster care
children with 71% of regular foster
care children receiving psychiatric
services compared to only about one
third (34.44%) of the non‐foster care
children (p<.0001).
Receipt of psychiatric services was also
examined to see if there were any
gender differences within each group.
As indicated in Figure 2.12, there were
no significant statistical differences in
receipt of psychiatric services among
regular foster care children by sex.
Nearly 73% of females and 70% of
males in the regular foster care
category received psychiatric services
during the study period. However,
among non‐foster children, males
(35.75%) were significantly more likely
to receive psychiatric services
compared to females (32.3%).

The highlights of Table 2.9 include:
There were no statistically significant differences among children in ISCEDC and regular foster
care categories by gender and area of residence (rural designation and social deprivation).
The proportion of minorities (African American and others) was significantly higher among
ISCEDC children (59.74%) compared to the regular foster care category (50.0%).
ISCEDC children were significantly more likely to be categorized under severe‐to‐catastrophic
CRG compared to those from the regular foster care category (89.94% vs. 63.01% respectively).
ISCEDC children were significantly more likely to have a listed psychiatric diagnosis compared to
regular foster care children (99.35% vs. 93.34% respectively).
ISCEDC children were significantly more likely to receive psychiatric services in addition to the
pharmacologic treatment compared to their regular foster care peers (91.67% vs. 71.0%
respectively).
Psychotropic Prescription Patterns
The majority of children in regular foster care category received a mono‐class treatment (68.14%). In
contrast, the majority of children in the ISCEDC category received multi‐class treatment (63.10%). As
indicated in Table 2.10 below, among these children, the top three drug classes prescribed included
ADHD medications followed by antidepressants and antipsychotics irrespective of whether the child
belonged to regular foster care or ISCEDC category. Significantly more children in ISCEDC category
received prescriptions for antidepressants (48.16%), antipsychotics (47.51%), and anticonvulsants
(24.35%) compared to those in regular foster care category (30.74%, 15.16%, and 11.37% respectively).
Significantly more children from the regular foster care category received ADHD medications (77.46%)
compared to their ISCEDC peers (73.27%).

The top three drug combinations among ISCEDC children included ADHD medications and
antidepressants (n=118, 12.77%); ADHD medications and antipsychotics (n=110, 11.90%); and ADHD
medications, antidepressants, and antipsychotics (n=89, 9.63%).
Among those who received multi‐class treatment, significantly more children in ISCEDC received
medications from more than one psychotropic drug class compared to children in the regular foster care
category (Table 2.11). The proportion of children in each category decreased as the number of
psychotropic drug classes increased. However, the differences in the proportions of children in each
group receiving medications from multiple psychotropic drug classes remained statistically significant
(Table 2.11).

The highlights of Table 2.13 include:
Psychotropic Prescription Patterns
More than two thirds of children in both categories received mono‐class treatment. As indicated in Table
2.14 below, among these children, the top three drug classes prescribed included ADHD medications
followed by antidepressants and antipsychotics irrespective of the child’s status (regular foster care vs.
adoption). Significantly more children in adoption category received prescriptions for ADHD medications
(84.86%) compared to regular foster care children (77.46%). On the other hand, significantly less children
in adoption category received antidepressants (23.62%) compared to their regular foster care peers
(30.74%). There were no significant differences in receipt of antipsychotics, anticonvulsants, and
antianxiety medications among the two groups (Table 2.14).

The two groups (adoption and regular foster care) did not differ significantly by gender.
Children in adoption category were significantly less likely to be categorized under severe‐to‐catastrophic CRG compared to those from the regular foster care category (58.84% vs. 63.01% respectively).
Children in adoption category were significantly less likely to have a listed psychiatric diagnosis compared to regular foster care children (89.92% vs. 93.34% respectively).
Children in adoption category were significantly less likely to receive psychiatric services in addition to the pharmacologic treatment compared to their regular foster care peers (46.18% vs. 71.0% respectively).
37
The top three drug combinations among children in adoption category included ADHD medications and
antidepressants (n=201, 8.93%), ADHD medications and antipsychotics (n=140, 6.22%), and ADHD
medications and anticonvulsants (n=52, 2.31%).
Among those who received multi‐class treatment, no significant differences were found by status (Table
2.15). Less than a third of children under adoption category received psychotropic medications from two
or more classes.

Psychiatric Diagnoses
Table 2.16 indicates reported psychiatric diagnoses among the children in regular foster care and
adoption categories. Children in adoption category were more likely to receive the diagnosis of ADHD
compared to their regular foster care peers (80.33% vs. 76.23% respectively). In contrast, regular foster
care children were significantly more likely to be diagnosed with adjustment disorders (44.47%), anxiety
disorders (9.63%), disruptive behavior disorders (30.33%), mood disorders (28.38%), and substance abuse
disorders (6.15%) compared to their peers in adoption category (Table 2.16).

CHAPTER 3: ANTIPSYCHOTIC PRESCRIPTION CLAIMS
As mentioned earlier, use of antipsychotic
medications is increasing among children and
adolescents. Antipsychotic medications are
classified into two major categories:
conventional and newer antipsychotics.
Conventional antipsychotic medications, also
called typical or first generation antipsychotics,
can cause serious side effects including extra‐
pyramidal side effects, weight gain, heart
disease, diabetes, pancreatitis, and other
metabolic disorders. Atypical or second
generation antipsychotics are effective and
cause fewer side effects compared to
conventional antipsychotics. For the list of
typical and atypical antipsychotics, please refer
to Appendix B1. Prescription patterns of antipsychotics in children enrolled in SC Medicaid during the
study period are presented here.
Profile of Children Receiving Prescriptions of Antipsychotic Medications
Of the total sample who received psychotropic medications, 7,221 (11.49%) received antipsychotic
prescriptions in CY 2011. Table 3.1 describes the profile of these children.
Demographic characteristics:
Irrespective of the child status, males were more likely to receive antipsychotic prescriptions
compared to females. The average age of children receiving antipsychotics was about 13.5 years.
Among both foster care and non‐foster care subsamples, the largest proportions of children receiving
antipsychotics were in the age groups of 10‐14 years followed by 15‐17 years. Thirty‐four children
under the age of 5 years received antipsychotic prescriptions. However, when the cut‐off point was
raised to include 5‐year olds, 112 children received antipsychotics. The proportion of African
American children receiving antipsychotics was higher in the regular foster care subsample (49.32%)
compared to non‐foster subsample (23.03%). Approximately 30% of children receiving antipsychotic
medications lived in rural areas. When examined by social deprivation indicator, overall 17.16% of
the sample lived in high deprivation areas.
Foster care status:
The majority of children receiving antipsychotics were non‐foster children (86.46%). Among all foster
care children (n=978), the largest proportions of children receiving antipsychotics belonged to ISCEDC
(44.93% of all fosters, 6.08% of total) category followed by adoption category (39.00% of all fosters,
5.28% of total).
40
Clinical characteristics:
The majority of children receiving antipsychotics were categorized under severe to catastrophic
clinical risk group (CRG) categories (92.62%). The proportions of children classified as severe‐to‐
catastrophic CRG did not differ significantly (p=.07) between regular foster children (88.51%) and
non‐foster children (92.54%) as well as between regular foster and adoption children (90.55%, p=48).
However, significantly more children under ISCEDC category (96.81%) were classified as severe‐to‐
catastrophic CRG compared to their regular foster peers (p<.0001). All children in regular foster care
category and nearly all children in ISCEDC category had listed psychiatric diagnoses. Compared to
regular foster care children, significantly lower proportions of non‐foster children (95%) and adoption
children (96%) had listed psychiatric diagnoses (p=.006 and p=.018 respectively). There were
significant differences in receipt of psychiatric services between children in regular foster care and
non‐foster care (p<.0001) as well as regular foster care and adoption categories (p=.0002).

Patterns of Antipsychotic Drug Prescriptions by Child Status, Gender, and Age
Figure 3.1 describes distribution
of children receiving
antipsychotic prescription by sex
and status. (Please note that
MCC category is not shown since
only 10 children in this category
received antipsychotic
medications.) Males were
significantly more likely to
receive antipsychotic
prescriptions compared to
females across all status
categories.
42
As indicated in Table 3.2, the majority of children receiving antipsychotic medications received multi‐class
treatment (87.83%). Of the children receiving antipsychotics, approximately 44% received medications
from three or more psychotropic drug classes and approximately 13% received medicines from four or
more drug classes. Significantly more children in ISCEDC category received three or more psychotropic
drug classes compared to those in regular foster care (p=.008). Further, among 112 children aged 5 years
or younger who received antipsychotics, nearly 3 out of every 4 children received multi‐class treatment.

Psychiatric Diagnoses
Table 3.3 indicates psychiatric diagnosis categories among children who received antipsychotic
prescriptions. Irrespective of their foster care status, less than 10% of children who received
antipsychotic medication prescription had reported psychotic disorder diagnoses. Among children who
received antipsychotic medication prescriptions, the top three psychiatric diagnostic categories included
ADHD (79.05%), mood disorders (58.78%), and disruptive behavior disorders (50.00%) among regular
foster care children; ADHD (65.67%), mood disorders (46.16%), and disruptive behavior disorders
(36.78%) among the non‐foster children; ADHD (84.74%), disruptive behavior disorders (78.13%), and
mood disorders (74.03%) among ISCEDC children; and ADHD (76.12%), mood disorders (50.39%), and
disruptive behavior disorders (42.52%) among adoption children. Statistically significant differences were
found in adjustment disorders between non‐foster (14.56%) and regular foster (47.97%, p<.0001),
between ISCEDC (58.31%) and regular foster children (p=.03), and between adoption (24.15%) and
regular foster children (p<.0001).

Antipsychotic Medication Adherence
Administrative pharmacy claims can provide quality metrics about medication utilization patterns,
including compliance, adherence, and persistence. Health outcomes related to pharmacy utilization
include compliance, adherence, and persistence measurements.14 The following indicators of drug
therapy management are used in this study.
Medication possession ratio. The medication possession ratio (MPR) is a measure of patient adherence
or compliance and is defined as the sum of a medication’s days of supply divided by the total number of
days in a time interval. While the most commonly used measure of adherence, MPR may overestimate
medication adherence when prescriptions are refilled before the previous supply of medication is
depleted. Compliance thresholds are based on the type of medication, disease of interest, or population
under study and typically range from 60%‐80%. In this study, optimal compliance for psychotropic
prescriptions is defined as 80% compliance or adherence with medication utilization with a maximum of
1.0. The results are reported in Table 3.4.
Proportion of days covered. In contrast to MPR, the proportion of days covered is a more conservative
estimate of adherence that measures each day with a supply of the medication(s) of interest over a
specific time period. The International Society for Pharmacoeconomics and Outcomes Research (ISPOR)
has urged for greater use of PDC in medication utilization research and CMS and PQA release
pharmaceutical quality data with PDC measures.15 For this study, the time interval for PDC is 180 days or
6 months, which is an acceptable level of observation of clinicians for patients using antipsychotic
prescriptions. The findings are reported in Table 3.5.

Two common measures of medication utilization adherence are the Medication
Possession Ratio (MPR) or Proportion of Days Covered (PDC). Optimal adherence is
defined at 80% for both measures in the study. The PDC is a more conservative
estimate of medication utilization and evidence suggests the metric is a more reliable
estimation of adherence. However, the MDC is still widely used. In this report, both
measures are used to estimate adherence to psychotropic medications, specifically
antipsychotic medications, among Medicaid children in the sample.
A mean possession ratio (MPR) lower than 0.8 indicates poor adherence to the drug prescribed.
Adherence to typical antipsychotic drugs was lower than the threshold, which indicates suboptimal
compliance. However, the overall adherence to all antipsychotic drugs and atypical antipsychotic drugs
was in acceptable levels. To investigate the adherence level of antipsychotic drug utilization, the main
ingredient or compound was aggregated. For example, haloperidol includes the brand name drug Haldol
and generic haloperidol. Poor adherence was detected in medication utilization of four antipsychotic
medications: aripiprazole (MPR=0.797), chlorpromazine (MPR=0.779), haloperidol (MPR=0.772), and
loxapine (MPR=0.738; Table 3.4).
Mean possession ratios as a measure of medication utilization has been criticized due to potential
overestimates of medication adherence. Using this traditional metric, poor adherence was noted in the
use of four antipsychotic medications; however, overall, the adherence rate was acceptable for all
antipsychotic drugs. In contrast to MPR, no antipsychotic drugs met the adherence threshold of 0.8 using
the proportion of days covered (PDC) measure.

Presence of Selected Non‐Psychiatric Diagnoses that Need Close Monitoring
Antipsychotic medications, particularly first generation antipsychotics are associated with side effects
including weight gain, cardiovascular complications, neurologic problems and movement disorders,
hyperglycemia, diabetes, pancreatitis, disorders of lipid metabolism, and metabolic syndrome X.
Presence of these diagnoses in children receiving antipsychotic medications needs careful clinical
monitoring. Table 3.6 displays the number of children who had above mentioned diagnoses and were
receiving antipsychotic medications. Please note that due to small cell sizes, regular foster care, ISCEDC,
adoption, and MCC categories are collapsed into one category of all foster care. Overall, 1,213 (16.8%) of
children receiving antipsychotic prescriptions also had one of the above mentioned medical conditions
listed on the claims data. There were no statistically significant differences overall or by selected
diagnostic conditions among all foster care and non‐foster children. Out of 978 foster children and 6,243
non‐foster children receiving antipsychotic prescriptions, 156 (15.95%) foster children and 1,057 (16.93%)
non‐foster children had one of these non‐psychiatric conditions.

CHAPTER 4: DISCUSSION
Summary of the Findings
The purpose of this report is to describe psychotropic
prescription patterns in children enrolled in the SC
Medicaid program. A total of 62,859 children who
received psychotropic medications in CY 2011 were
included in the sample. In a retrospective analysis of
prescription claims from CY 2009 through CY2011, the
prescription patterns of psychotropic medications,
associated psychiatric diagnoses, and receipt of
psychiatric services as an adjunct to pharmacological
treatment were examined.
The majority of the approximately 63,000 children in the
sample did not belong to the foster care system and were
more likely to be White, male, and live in urban areas.
Among children in regular foster care, the proportion of
males was 57.8%. Nationally, an estimated 52% of
children in foster care in 2010 were males. 16 More
children in foster care category receiving psychotropic
medications were African American, older, and lived in
socially deprived urban areas compared to their non‐
foster peers. In a measure of risk of clinical diagnoses,
foster care children had higher rates of severe or complex
clinical conditions. It should be noted that the regular
foster care category excluded children who were adopted
or classified as ISCEDC or MCC.
Prescribing patterns of the eight psychotropic drug classes were examined during the study period. More
than three quarters of the children in the sample received prescriptions from a single psychotropic drug
class. Significantly more children in regular foster care received psychotropic medications from multiple
drug classes compared to non‐foster children. This could be attributed to higher need of psychotropic
medications among foster care children due to their vulnerability to biological, psychological, and social
risk factors that are commonly associated with foster care status. However, it is also possible that there
may be provider bias in prescribing medications from multiple psychotropic drug classes for foster care
children compared to non‐foster children. Among the foster care children, children in ISCEDC category
were significantly more likely to receive multi‐class treatment compared to regular foster care children.
These differences persisted whether the cut‐off is selected at two or more; three or more; or four or
more drug classes for defining multi‐class psychotropic treatment. This could be attributed to higher
mental health needs among children in ISCEDC category compared to their regular foster peers. The most
commonly prescribed psychotropic drug class combinations included ADHD medications‐antidepressants
followed by combination of ADHD medications‐antipsychotics irrespective of the child’s status.
49
ADHD and antidepressant medications were the top two psychotropic prescriptions among children
irrespective of their status. Males were more likely to receive ADHD medications and females were more
likely to receive antidepressants compared to their respective peers. Nearly one out of two children in
ISCEDC category receiving psychotropic medications received prescription for antipsychotic medication.
The proportion of ISCEDC children who received antipsychotic prescriptions was nearly 3 times the
proportion of regular foster children who received antipsychotic prescriptions. In contrast, the proportion
of non‐foster children receiving antianxiety medications was nearly 2 times the proportion of all foster
care children receiving antianxiety medications. Small proportions of children received barbiturate
sedatives, mood stabilizers, and non‐barbiturate sedatives irrespective of their foster care status. Among
children receiving antipsychotic prescriptions, nearly 88% children received multi‐class treatment. A
significantly higher proportion of regular foster care children (~92%) on antipsychotics, received multi‐
class treatment compared to non‐foster children on antipsychotics (~87%). Further, slightly more than
13% of the total children with antipsychotic prescriptions received prescriptions from four or more
psychotropic drug classes. This proportion was higher compared to previously reported rates of 11.8% in
2004 and 10.9% in 2007 among children and adolescents from 16 states in the analysis of psychotropic
medication use. 17 Another area of concern found among children receiving antipsychotic prescription
was that 112 children, majority being non‐foster children, aged 5 years or younger received antipsychotic
medications. Further, nearly three fourths of these children (82 out of 112) received multi‐class
treatment. In a report by the Medicaid Medical Directors Learning Network and Rutgers Center for
Education and Research on Mental Health Therapeutics, the use of antipsychotic medications among
children 5 years or younger and use of multiple mental health drugs (four or more) during a calendar year
were considered as preliminary measures to indicate potential quality and safety issues in psychotropic
pharmacological treatment. 17
In a measure of adherence to antipsychotic medications, overall adherence was within acceptable levels
using the calculated mean possession ratio. In a comparison of typical and atypical antipsychotic
medications, adherence to typical or conventional antipsychotic medications was lower than the
threshold level indicating optimal compliance. Lower adherence was noted using a more conservative
estimate of medication compliance. However, there is a lack of consensus about the appropriate
measure to use in children receiving psychotropic medications.
ADHD was the most common psychiatric diagnosis reported among children in the sample irrespective of
their foster care status. Adjustment disorders, disruptive behavior disorders, and mood disorders
followed ADHD among regular foster care children while disruptive behavior disorders, mood disorders,
and adjustment disorders followed ADHD among non‐foster care children. It was noteworthy to find that
nearly 17% of children who received psychotropic prescriptions had no listed psychiatric diagnosis in their
claims data. This proportion (no listed psychiatric diagnosis) was significantly lower among regular foster‐
care children compared to non‐foster care children. Among non‐foster children, nearly one in five
children who received mono‐class psychotropic treatment and one in ten who received multi‐class
treatment did not have listed psychiatric diagnosis. This is certainly an area of concern since there may be
cases where children are receiving psychotropic medications without indication. Among children who
received antipsychotic medications (which are prescribed to treat a psychotic disorder such as
schizophrenia, delusions, or other psychosis), less than 10% had a diagnosis of psychotic disorder. None
of the children receiving antipsychotics had a listed diagnosis of schizophrenia. It is possible that
50
providers refrain from assigning a schizophrenia diagnosis to children given its serious implications due to
associated stigma. Very few were diagnosed with delusional disorder. The majority of the children with a
psychotic disorder diagnosis had received a diagnosis of “other psychotic condition.” Nearly 66% of non‐
foster, 80% of regular foster, 79% of ISCEDC, and 76% of adoption children receiving antipsychotics were
diagnosed with ADHD.
In general, it is recommended that psychotropic pharmacotherapy be combined with other evidence‐
based protocols such as psychotherapy, family skills training or behavior management, etc. Overall,
slightly more than one third of all children received psychiatric services as adjunct to pharmacological
treatment. Such low rates of receiving psychiatric services could possibly be due to higher reliance on
pharmacological treatment than other psychiatric services by providers or by shortage of child and
adolescent psychiatrists and clinical psychologists. More than 70% of regular foster care children, in
contrast to only about a third of non‐foster children, received psychiatric services. It is not clear why the
majority of non‐foster children did not receive adjunct psychiatric services. There is a possibility that
providers may offer psychiatric services as adjunct to pharmacotherapy in foster care children due to
their unique circumstances and new family dynamics. The highest proportion of children receiving
psychiatric services was among children in ISCEDC category where nine out of ten children received such
services. This was an expected finding since children in ISCEDC category have emotional instability and
need more psychiatric services. The proportion of children receiving psychiatric services was also higher
among those receiving antipsychotic medications with nearly seven out of every ten children receiving
the adjunct services.
In the ISCEDC category, nearly three in four children received ADHD medications and nearly one in two
children received antidepressants and antipsychotics. Further, nearly 63% of ISCEDC children received
medications from two or more psychotropic drug class. Even when the cut‐off point for defining a multi‐
class treatment was raised to the receipt of three or more drug classes, nearly 30% of ISCEDC children fell
under the multi‐class treatment category. These findings reflect a greater vulnerability of these children
and higher need to provide quality mental health care to children with emotional disturbances. Children
in adoption category were found to be significantly less likely to have received antidepressants compared
to their regular foster peers. It is possible that children once adopted may perceive that they have a
secured “home” environment and feel less depressed compared to regular foster care children.
Many children in the foster care system have a myriad of complex health needs, which require care
coordination of “preventive, diagnostic, and treatment services.” 18 Higher rates of primary care and
behavioral health utilization were reported in foster care children and the delivery of such services was
often fragmented and episodic. 18 Similar to the national trends, more children in regular foster and
ISCEDC categories in our sample lived in areas with high social deprivation compared to those in non‐
foster category and had more severe or complex clinical risk categories. Within the levels of foster care,
ISCEDC and MCC children had even higher rates of high risk clinical diagnoses and ISCEDC and adoption
children were prescribed antipsychotic drugs more often than regular foster care children. Overall, the
health profile and psychotropic medication utilization patterns in SC Medicaid children in this sample
suggest the need for the delivery of quality pediatric mental health services using coordinated,
comprehensive, and patient‐centered mechanisms.
51
The complexity of delivering quality and efficient services to foster care children is illustrated in the figure
below (Figure 4.1).18 In addition to the care coordination across service providers, the figure also
illustrates the complexity of navigating different structural and policy divisions across state agencies, such
as the Department of Social Services (DSS), Department of Mental Health (DMH), and the Department of
Health and Human Services (DHHS). As a foster care child moves through various outlets in the model,
there is an opportunity to strengthen the safety net of health services available with continuous
monitoring of performance measures and patient outcomes.
The study findings with this population of children in SC Medicaid can inform strategic policy initiatives and quality improvement efforts of the policymakers and stakeholders represented in the health care delivery model for children in foster care.
Previously Recommended Protocol Standards and Psychotropic Drug Safety
The American Academy of Child and Adolescent Psychiatry (AACAP) has issued several practice
parameters for delivery of care from both the patient and clinician perspectives. One of the AACAP
practice parameters for clinicians is an overview of the use of psychotropic medication in children and
adolescents.1 This parameter consists of five sections including assessment, development of treatment
Figure 4.1. Health Care Delivery Model for Children in Foster Care [Source: Inkelas M & Halfon N.(2002). Medicaid and Financing of Health Care for Children in Foster Care: Findings from a National Survey. UCLA Center for Health Children, Families, and Communities. Policy Brief Series.]
52
and monitoring plan, psycho‐education and assent/consent procedures, implementation of treatment
and monitoring plan, and management of complex pharmacological interventions. Thirteen principles
related to each of these five sections (Table 4.1), intended for clinicians, are based on evidence and
professional consensus among clinicians.1
Table 4.1. AACAP Practice Parameters for Use of Psychotropic Medications Among Children
AACAP Practice Parameter
AACAP Principles
Assessment 1. Before initiating pharmacotherapy, a psychiatric evaluation is completed.
2. Before initiating pharmacotherapy, a medical history is obtained, and a medical evaluation is considered when appropriate.
3. The prescriber is advised to communicate with other professionals involved with the child to obtain collateral history and set the stage for monitoring outcome and side effects during the medication trial.
Development of treatment and monitoring plan
4. The prescriber develops a psychosocial and psychopharmacological treatment plan based on the best available evidence.
5. The prescriber develops a plan to monitor the patient, short and long term.
6. Prescribers should be cautious when implementing a treatment plan that cannot be appropriately monitored.
Assent and consent for treatment
7. The prescriber provides feedback about the diagnosis and educates the patient and family regarding the child’s disorder and the treatment and monitoring plan.
8. Complete and document the assent of the child and consent of the parents before initiating medication treatment and at important points during treatment.
9. The assent and consent discussion focuses on the risks and benefits of the proposed and alternative treatments.
Implementation of treatment and monitoring plan
10. Implement medication trials using an adequate dose and for an adequate duration of treatment.
11. The prescriber reassesses the patient if the child does not respond to the initial medication trial as expected.
12. The prescriber needs a clear rationale for using medication combinations.
Management of complex pharmacological interventions
13. Discontinuing medication in children requires a specific plan.
Specific to children in state custody, AACAP has issued a position statement and guidelines for best
principles on the oversight of psychotropic medication use for children in state custody.8 Six basic
principles are outlined to improve psychiatric care of children in state custody. In addition, four
guidelines are proposed to assist states in developing state‐specific psychotropic medication oversight
programs with minimal, recommended, and ideal strategies for implementation. First, states are advised
53
to establish policies and procedures to guide psychotropic medication management with accompanying
strategies of minimal, recommended, and ideal impact. Secondly, states are cautioned to design and
improve oversight procedures within a collaborative body of child welfare agencies and adolescent
psychiatrists. Other best practices guidelines are to design a consultation program and create a website
to disseminate information to various stakeholders, including clinicians, caregivers, and foster parents
(Table 4.2).
Table 4.2. AACAP Guidelines for Psychotropic Medication Use Among Foster Care Children
AACAP Best Principles Guidelines Strategies
Establish policies and procedures to guide the psychotropic medication management of youth in state custody
Identify the parties empowered to consent for treatment for youth in state custody in a timely fashion [minimal].
Establish a mechanism to obtain assent for psychotropic medication management from minors when possible [minimal].
Obtain simply written psycho‐educational materials and medication information sheets to facilitate the consent process [recommended].
Establish training requirements for child welfare, court personnel and/or foster parents to help them become more effective advocates for children and adolescents in their custody [ideal].
Design and implement effective oversight procedures
Establish guidelines for the use of psychotropic medications for youth in state custody [minimal].
Establish a program, administered by child and adolescent psychiatrists, to oversee the utilization of medications for youth in state custody [ideal].
Maintain an ongoing record of diagnoses, height and weight, allergies, medical history, ongoing medical problem list, psychotropic medications, and adverse medication reactions that are easily available to treating clinicians 24 hours a day [recommended].
Consultation program State child welfare agencies, the juvenile court, or other state or county agencies empowered by law to consent for treatment with psychotropic medications, should design a consultation program administered by child and adolescent psychiatrists [recommended].
Website State child welfare agencies, the juvenile court, or other state or county agencies empowered by law to consent for treatment with psychotropic medications, should create a website to provide ready access for clinicians, foster parents, and other caregivers to pertinent policies and procedures governing psychotropic medication management, psycho‐educational materials about psychotropic medications, consent forms, adverse effect rating forms, reports on prescription patterns for psychotropic medications, and links to helpful, accurate, and ethical websites about child and adolescent psychiatric diagnoses and psychotropic medications [ideal].
54
Other federal and state agencies have used the AACAP’s practice parameters and best practices
guidelines to evaluate the effectiveness of existing and planned psychotropic medication management
programs. The Medicaid Medical Directors Learning Network has issued similar recommendations
including state‐specific programs and policies to monitor psychotropic medications, a collaborative forum
to promote discussion of new and existing policies with diverse stakeholders, and creation of a repository
of state‐specific programs and best practices to increase dissemination of effective interventions.
In a GAO comparative analysis of psychotropic drugs prescribed for foster and non‐foster care children in
Medicaid, five states were rated in their implementation of AACAP best practices on six criteria. In the
GAO evaluation, Texas and Michigan programs were considered at the forefront of psychotropic
prescription oversight. For example, Texas has designed and implemented state‐specific practice
parameters for psychotropic medication utilization and continuously analyzes medication prescription
patterns using an overhauled claims data system. In addition, the state has implemented an adverse
event reporting system with retrospective chart review, case series, and single case reports. Minimal and
ideal requirements for psychotropic medication management oversight suggested by the GAO are
indicated below (Table 4.3).
Table 4.3. GAO Guidelines for Psychotropic Medication Management Oversight
Level Guideline
Minimal Establish guidelines for the use of psychotropic medications for children in state custody.
Ideal Oversight program includes an advisory committee to oversee a medication formulary and provide medication monitoring guidelines to practitioners who treat children in the child welfare system.
Ideal Oversight program monitors the rate and types of psychotropic medication usage and the rate of adverse reactions among youth in state custody.
Ideal Oversight program establishes a process to review non‐standard, unusual, and/or experimental psychiatric interventions with children who are in state custody.
Ideal Oversight program collects and analyzes data and makes quarterly reports to the state or county child welfare agency regarding the rates and types of psychotropic medication use. Make this data available to clinicians in the state to improve the quality of care delivered.
Ideal Maintain an ongoing record of diagnoses, height, and weight, allergies, medical history, ongoing medication problem list, psychotropic medications, and adverse medication reactions that are easily available to treating clinicians 24 hours a day.
Adapted from GAO Report, 2011.
In South Carolina, according to the SC Department of Social Services protocol, every child entering the
foster care system should complete initial mental health assessment within 24‐48 hours and initial
comprehensive medical assessment within 5 days of the entry into the system.19 Initial mental health
screening of a child can be conducted by mental health professional or a pediatrician. The protocol also
requires obtaining mental health and behavioral information regarding the child from the parents,
55
relatives, or others and sharing this information with the foster parents and providers in order to meet
the child’s mental health needs. However, there are no specific protocols related to prescriptions and use
of psychotropic medications among children enrolled in SC Medicaid including those in the foster care
system. Currently, the SC Department of Health and Human Services, SC Department of Social Services,
and SC Department of Mental Health are working together to develop guidelines and protocols for
prescribing psychotropic medications among SC Medicaid children including foster care children.
Recommendations
Based on the study findings and a brief review of established guidelines related to psychotropic
medication, the following recommendations are offered. There are several opportunities to improve the
oversight and management of psychotropic medications prescribed to children in Medicaid proactively
and in a holistic manner.
Recommendation 1:
Psychiatric diagnosis must be documented by applying specific diagnostic criteria using screening and
evaluation protocols for children, youth, and adolescents enrolled in SC Medicaid irrespective of their
foster care status.
These recommendations include:
Psychiatric diagnosis must be documented by applying specific diagnostic criteria using
screening and evaluation protocols for children, youth, and adolescents enrolled in SC
Medicaid irrespective of their foster care status.
A comprehensive mental health treatment plan that includes psychiatric services as
alternative or adjunct to pharmacological treatment and provisions of second opinion by
a qualified psychiatrist when appropriate should be developed by a psychiatrist in
consultation with the primary care provider.
Regular monitoring of psychotropic medication prescription patterns/use should be
conducted on a semi‐annual basis.
Information exchange and care coordination among providers, patients, and caregivers
should be considered critical elements of overall patient management plan.
Training and continuing education programs for providers should include mandatory mental
health components and updates related to changes in clinical practice guidelines related to
psychotropic medication use among children and adolescents.
Establish a psychotropic medication oversight advisory committee consisting of a wide range
of stakeholders to oversee psychotropic medication prescriptions for children and
adolescents enrolled in Medicaid with annual reports to state agencies.
56
It is evident from the study findings that nearly 17% of children enrolled in SC Medicaid who received a
psychotropic prescription in calendar year 2011 had not had listed psychiatric diagnoses. Nearly one in
two children who received antianxiety medications and one in five who received antidepressant
medication did not have a listed psychiatric diagnosis. Even for children who received antipsychotic
medications, nearly 5% did not have a psychiatric diagnosis. Lack of listed diagnoses limits the ability to
justify use of psychotropic medications among these children. These findings highlight the need of
documenting psychiatric diagnosis as outlined in the DSM‐IV before initiating psychotropic medications.
Initial mental health evaluation of children entering the foster care system should also include screening
for depression and substance use given the potential trauma experienced by these children. Regular
screenings and mental health evaluations should be a part of the protocol for all foster care children to
detect behavioral and emotional problems as well as adjustment issues at the earliest so that prompt and
effective management can be offered.
Recommendation 2:
A comprehensive mental health treatment plan that includes psychiatric services as alternative or
adjunct to pharmacological treatment and provisions of second opinion by a qualified psychiatrist
when appropriate should be developed by a psychiatrist in consultation with the primary care
provider.
After an initial evaluation and documented need for treatment, a comprehensive mental health
treatment plan should be developed by the psychiatrist in consultation with the child’s primary care
provider. It is recommended that non‐pharmacological psychiatric services such as counseling,
family/group therapy, or behavioral and cognitive therapy, etc., be tried first, prior to initiating
pharmacological treatment unless medications are absolutely indicated. Even for those children who
need medications to treat or control their mental health conditions, use of such psychiatric services as
adjunct to pharmacological treatments is recommended given that such combination improves mental
health outcomes and medication adherence. In our sample, nearly twice as many foster care children
received psychiatric services compared to non‐foster children. The results indicate differential treatment
for children in foster care compared to children not in foster care; however, it is unclear from the data
the reasons for the discrepancy in receipt of psychiatric services. This finding indicates a need for
standards about the appropriateness of adjunct therapy to be clearly communicated to providers. These
metrics, which may be endorsed by state agencies to improve implementation across providers and
practices,9, 10 can be continuously monitored using claims data to track changes in receipt of other
psychiatric services along with psychotropic medications.
Treatment protocols should be based on scientific evidence and up to date information related to
individual medication including its approved clinical use. As possible, established protocols should be
followed or adapted in formulating a specific treatment plan. The American Academy of Pediatrics (AAP)
Task Force on Mental Health20 and expanded scope ADHD clinical practice guidelines 21 are examples of
evidence‐based clinical protocols, which can be adopted to standardize the delivery of mental health
services to Medicaid children.
It is also recommended to include behavior modification plans, whenever necessary, to improve rates of
medication adherence. The findings from this analysis indicated that medication adherence was sub‐
57
optimal for antipsychotic medications when a stricter measure of adherence was used. Medication
adherence to psychotropic medications is critical in treatment outcomes since deviations from prescribed
dosage and frequency may have undesirable implications.
It is strongly recommended that this comprehensive plan be developed by the psychiatrist and the
primary care provider with mutual consultation to fit the specific needs of the individual child. It is also
recommended that an opinion by a second psychiatrist must be obtained before starting pharmacological
treatment for children aged 5 years or younger as well as for those children who need more than two
psychotropic medications concurrently.
Recommendation 3:
Regular monitoring of psychotropic medication prescription patterns/use and other psychiatric services
should be conducted on a semi‐annual basis.
After the initiation of pharmacological treatment, psychotropic prescriptions including antipsychotics
should be monitored regularly using Medicaid claims data on a semi‐annual basis. These semi‐annual
reports should include information of all the psychotropic medications prescribed to the patient
(medication names, dose, frequency, and duration), patient’s response to the treatment, side effects of
the prescribed medications if any, indication for changing or adding new medication(s), and utilization of
adjunct psychiatric services.
Such monitoring will allow officials to identify overuse of psychotropic prescriptions or underuse of
adjunct psychiatric services in children enrolled in Medicaid. It will also allow officials to identify
questionable prescription patterns such as antipsychotic prescriptions to children aged 5 years or
younger, prescription of four or more psychotropic medications in a single calendar year, and off‐label or
un‐indicated use of psychotropic medications. The study results indicated that more than 100 children 5
years or younger received antipsychotic prescriptions and that one out of every four of these children
received multi‐class treatment. Further, more than 10% of children receiving antipsychotic prescriptions
received four or more psychotropic medications. These findings raise serious concerns over potential
impact of multiple psychotropic medications among children. Similar to results found in other studies of
children receiving mental health care in South Carolina Medicaid, 11 children in this sample received more
atypical antipsychotics than conventional antipsychotic medications. While adherence rates for atypical
antipsychotics compared to conventional antipsychotic medications were mixed, careful monitoring of
prescribing patterns and adherence across patient populations is warranted.
Other questionable psychotropic prescriptions were also identified which are either not approved for use
in children or not recommended for children with mental health diagnoses. For example, the
antidepressant drug paroxetine (Paxil) is not approved for use in children less than 18 years for the
treatment of depression by the Food and Drug Administration (FDA). FDA issued warnings advising
clinicians of adverse effects in patients younger than 24 years of age, including hallucinations and suicide,
in 2003 and 2005, which resulted in lower rates of prescriptions among children and adolescents. 22‐24
Paroxetine was prescribed to children in our sample. Similarly, Provigil and Nuvigil, which are not
approved for use in children under age of 18 years are often used off‐label by pediatricians. 24 In our
study sample 26 children were prescribed Provigil‐Nuvigil and of these 14 children were under 18 years
58
of age. Tracking and reporting such prescriptions can lead to improvements in the quality of care by
limiting unapproved psychotropic medications prescribed to children. Medication management programs
and electronic prescribing can include reminders about FDA warnings and prevent questionable
psychotropic prescriptions to children.
Recommendation 4:
Information exchange and care coordination among providers, patients, and caregivers should be
considered critical elements of overall patient management plan.
Information exchange between providers, patients, and caregivers is critical in ensuring accurate
diagnosis, development of treatment and management plan and adherence to the prescribed plan which
will ultimately result in better patient outcomes. As mentioned earlier, patients and caregivers should be
informed about the clinical evaluation, diagnosis, and available treatment options. In addition, prior to
starting pharmacological treatment, the risks and benefits of psychotropic medications should be clearly
communicated with patients and their caregivers. Emphasis should also be placed on the need for
optimal medication adherence and reporting of side effects. The information exchange should be done in
a culturally and linguistically appropriate manner. This will help establish a trusting relationship with the
health care provider.
Care coordination is another critical element in optimizing treatment protocols and health outcomes.
Quality health care delivery to children receiving psychotropic medications, especially those in the foster
care system, requires coordination across providers, practices, and community service agencies. As
illustrated in Figure 4.1, careful coordination across these entities will enhance the delivery of care to
children in foster care. Continuous monitoring of referrals to behavioral health providers can improve the
information exchange across facilities. A formal mechanism of health information exchanges should be
established to promote care coordination across providers, practices, and caregivers caring for the
children in foster care system. In particular, electronic resources to store and communicate patient
information can improve delivery of care after hours, which may minimize costs associated with adverse
events for children receiving psychotropic medications. Another recommendation is to use a case
management approach to coordinate care among high risk children.
Use of technology such as short message system (SMS) or text message reminders about upcoming
doctor appointments or prescription refills can be considered to improve treatment adherence.
Additionally, information about mental health conditions, psychotropic medications, their potential
indications, contra‐indications, and side effects as well as responses to other frequently asked questions
can be uploaded on state agency websites. This information can be shared with patients and caregivers
to enhance patient education and support patient empowerment.
Recommendation 5:
Training and continuing education programs for providers should include mandatory mental health
components and updates on changes in clinical practice guidelines related to psychotropic medications
use among children and adolescents.
With evolving treatment for mental health conditions and new developments in criteria for childhood
mental health conditions and appropriate treatment options including psychotropic medications, it is
59
important that health care providers serving Medicaid children have up‐to‐date knowledge about
treatment recommendations and clinical guidelines in management of childhood psychiatric conditions.
Therefore, training and continuing education programs for providers must include mandatory mental
health components and information updates related to use of psychotropic medications among children
and adolescents.
The claims data are critically important in monitoring clinical measures and the quality of care delivered,
especially since the costs of observation are prohibitive and difficult to implement in population‐based
studies. However, the quality of data can be hampered by data entry errors on the practice level. Efforts
to train practice staff and providers about upcoming changes to CPT code list may prevent limitations in
the use of claims data and clinical data in the electronic health record system for other quality monitoring
reports. 25
Health care providers are also influential in improving adherence rates. In one study, clinician beliefs
about their ability to influence adherence to antipsychotic medications and educate patients using
evidence‐based strategies were found to be strong facilitators of medication adherence.26 However, in a
study of mental health case managers, nearly half of mental health nurses reported no training in
medication adherence strategies.27 Monitoring adherence using a standard metric will allow for an
evaluation of differences in adherence rates across providers and practices. Providers with lower
adherence rates should be targeted for additional training and education in adherence strategies.
Recommendation 6:
Establish a psychotropic medication oversight advisory committee consisting of a wide range of
stakeholders to oversee psychotropic medication prescriptions for children and adolescents enrolled in
Medicaid with annual reports to state agencies.
The oversight committee should include multiple stakeholders (clinicians, psychiatrists, pharmacists, case
managers, state agency staff, and caregivers) to oversee psychotropic medication prescriptions for
children, youth, and adolescents enrolled in Medicaid with annual reports to state agencies. Such
collaborative efforts to oversee psychotropic medication prescriptions will help improve quality of care
and ultimately health outcomes among Medicaid children with mental health needs.
Implications of Findings and Suggestions for Future Research
It is clear from the study findings that there is an urgent need to develop clinical guidelines and practice
protocols for prescribing psychotropic medications to children enrolled in SC Medicaid. Given that
multiple players at multiple levels influence health care services delivered to the most vulnerable
children in Medicaid (i.e. who need psychotropic medications for their mental health needs),
coordination of care becomes a critical element in care provision. Integration of health care and other
services including but not limited to primary care, psychiatric care (both pharmacological and adjunct
services), case management, social services, patient/caregiver education, and use of technology is
needed for optimal results. A patient‐centered medical home model can serve as the best conceptual
framework for providing quality care to children with mental health needs who are enrolled in Medicaid.
The common elements of a patient‐centered medical home which facilitate the effective delivery of
quality care are: (a) personal physician, (b) team practice, (c) coordinated care, (d) health information
60
technology and analytical tools, (e) expanded access to health providers, and (f) effective use of financial
services.28
Future avenues for research to inform public health practice include an analysis of prescribing patterns
for specific psychotropic drug classes, particularly ADHD and antidepressants among children using
Medicaid, poly‐pharmacy of psychotropic medications in children with chronic diseases such as diabetes,
and a qualitative investigation of the experiences of foster care parents and caregivers of children with
mental health diagnoses. In addition to the recommendations provided in this report, future studies can
identify other areas of improvement or reorganization of care delivery to children enrolled in Medicaid
with mental health diagnoses.
Study Limitations and Strengths
There are several limitations that need to be considered while interpreting the results. This report
described psychotropic prescription patterns among foster care and non‐foster care children enrolled in
SC Medicaid. This analysis was restricted to children who received at least one psychotropic medication
prescription in CY 2011 and so the results cannot be generalized to other state Medicaid populations. It is
also possible that the estimates of the prevalence of mental health disorders in children enrolled in SC
Medicaid may be underestimated due to incorrect or incomplete reporting. These errors can also occur in
entering clinical data into the electronic health record (EHR), which further underscores the importance
of training providers and support staff in coding.25 In context of the antipsychotic medication adherence
results, readers need to be aware that pharmacy claims data are limited in medical utilization studies
because the data do not reflect actual use or consumption of medications prescribed14 or the use of
pharmaceutical samples provided by providers.29 However, pharmacy claims data have been found to be
acceptable proxies for medical utilization and health outcomes research,30 particularly in patient
populations with only one source of pharmaceutical reimbursement, such as Medicaid recipients.31
Despite these limitations, study findings offer preliminary understanding of psychotropic prescription
patterns among vulnerable children enrolled in SC Medicaid. Recommendations for improving the quality
of mental health services to children enrolled in Medicaid offered in this report will likely assist other
states with poorer health rankings and similar population characteristics.
Conclusions
Children and adolescents in foster care are particularly vulnerable to mental health conditions. In an
examination of psychotropic medication prescribing patterns, differences in the delivery of mental health
treatment to children in foster care compared to other children were noted. Continued quality
improvement efforts to monitor outcomes in foster care children enrolled in Medicaid across providers
and populations will illuminate sources of these differences and inform strategies in how best to
reorganize delivery of quality mental health services to children in foster care.

TECHNICAL NOTES
The study used Medicaid claims data stored at the Institute for Families in Society (IFS) under contract to the SC Department of Health and Human Services. The sample included Medicaid beneficiaries aged 21 years or younger who received at least one prescription of psychotropic medication in calendar year 2011. All analyses were done using a de‐identified data set that included variables of interest extracted from recipient family file, A claims, D claims, and Z claims. All Medicaid claims [physician (A claims), pharmacy (D claims), and hospital (Z claims)] for each sampled beneficiary were extracted for calendar years 2009, 2010, and 2011. Dataset included unique identifier, age (as of December 31, 2011), sex, race, child status (as of December 31, 2011), drug class of psychotropic medication, Medicaid qualifying category, Medicaid assistant payment category, claim number and type, dates of service (begin and end date), site of service, provider type, diagnosis and procedure codes (ICD9, DRG, CPT, and HCPCS); clinical risk group (CRG) category, rural‐urban commuting area (RUCA) code, and unique indicator for social deprivation [Palmetto Small Area Deprivation Index (PSADI)]. For D claims, names of medications prescribed, national drug codes (NDC), date on which a particular prescription was dispensed, duration for which the medication was dispensed, and amount of medication supplied were also considered. This information was particularly useful in examining compliance or adherence to psychotropic drugs which was measured by two indicators [medication possession ratio (MPR) and proportion of days covered (PDC)] calculated from the original variables. For Z claims, days in hospital and DRG classification were considered. Multiple claims records for the same beneficiary are linked by using a distinct identification number (medinum).
Variables of interest and their definitions
The total Medicaid population in the eligible age group is comprised of 465,000 enrollees. Approximately 14% or 62,859 children comprised the study population. Of these, 4,012 (7%) were associated with a foster care placement. The Medicaid beneficiaries of interest were categorized based on their status into two broad groups: foster care children (who were under the state custody as of December 31, 2011) and non‐foster care children (who were not under the state custody, but enrolled in SC Medicaid as of December 31, 2011). Foster care children were further classified into one of the following categories: children who were adopted (adoption), children with emotional problems [those who were eligible for interagency system of care for emotionally disturbed children (ISCEDC)], children with complex medical conditions (MCC), and regular foster care.
Children in our sample were categorized into five age groups: less than 1 year, 1‐4 years, 5‐9 years, 10‐14 years, 15‐17 years, and 18‐21 years. Race was categorized into three categories: White/Caucasian, Black/African American, and Other. Nine levels of clinical risk group classification were examined for each child. The CRG status was dichotomized into mild or moderate (CRG<5) and severe (≥5). Area of residence was classified using the RUCA codes into urban, large rural, small rural, and isolated rural. In addition, we also classified children into three categories (urban high deprivation, rural high deprivation, and small‐to‐moderate deprivation) based on a special indicator for social deprivation (PSADI). The PSADI (similar to Townsend Index for Social Deprivation32) was created using special indicators specifically designed for South Carolina to indicate areas of social deprivation.
Nine drug classes for psychotropic medications were considered for the analysis. They included ADHD drugs, antianxiety drugs, anticonvulsants, antidepressants, antipsychotics, barbiturates, mood stabilizers, non‐barbiturate sedatives, and Provigil Nuvigil. These drug classes were extracted from the recipient family file. Since the frequency of children who received Provigil Nuvigil was less than 30 (n=26), they
62
were not included in further analysis. For the analysis specific to prescription antipsychotics, appropriate NDCs were flagged to obtain frequency of children receiving each specific antipsychotic medication.
Children were categorized into eight psychiatric diagnostic categories based on reported ICD‐9 codes. These diagnostic categories included:
1) Attention deficit and hyperactivity disorder [ADHD (ICD9=314)];
2) Adjustment disorders (ICD9=309.0 and 309.1);
3) Anxiety disorders (ICD9=300.00);
4) Disruptive behavior disorders [conduct disorder (312), oppositional defiant disorder (313.81)];
5) Mood disorders [bipolar disorder (ICD9=296), depressive disorder not classified elsewhere (ICD9=311), and dysthymic disorder (ICD9=300.4)];
6) Pervasive developmental disorders (ICD9=299.0‐299.8);
7) Psychotic disorders [schizophrenia (ICD 9 = 295 & 299.9), delusional disorders (ICD 9 = 297), and other non‐organic psychoses (ICD 9 = 298)]; and
8) Substance abuse disorders [alcohol dependence syndrome (303), drug dependence (304), non‐dependent drug abuse (305)].
Additionally, for the children who received antipsychotic medications, the records were flagged if they had the following ICD‐9 codes: 250 (diabetes), 783.1 or 278.0 (weight gain), 790.29 (hyperglycemia), 277.1 or 277.7 (metabolic syndrome), 577 (pancreatitis), 333.85 or 333.72 (neurological problems/movement disorder), 410, 411, 412, 413, 414, 426, 427, 428, 431, 432, 433, 434, 435, 436, 780.2 or 798 (cardiovascular conditions) to identify possible side effects of antipsychotic medications.
Outcome variables of interest included: 1) receipt of psychotropic medication from a particular drug class (coded yes or no for each of the drug classes mentioned above), 2) receipt of multi‐class treatment (coded yes or no depending on whether the beneficiary has received psychotropic prescriptions from two or more drug classes), and 3) receipt of psychiatric services other than pharmacologic treatment [coded as yes or no using the following specific CPT codes (Please refer to Appendix D for description of codes) S8180, S8181, S8184, S8185, S8186, H2029, 90804, 90806, 90808, 90810, 90812, 90814, 90816, 90818, 90821, 90823, 90826, 90828, 90849, 90853, 90857, 90870, 90875, 90876, 90880, 90901, 96100, 96151, 96152, 96153, 96154, 96155, 90846, 90847, 99241]. Independent variables included age, sex, race, child status, and psychiatric diagnosis (coded yes or no) whereas control variables included CRG category, RUCA codes, and PSADI.
Descriptive statistics were conducted to describe characteristics of children (in each status category) who received psychotropic medication in CY 2011. Each outcome variable of interest is examined by age group, sex, race, child status, and psychiatric diagnosis. Additionally, among those who received antipsychotic prescription, proportion of children with ICD‐9 diagnosis suggesting potential side‐effects of antipsychotic medication is also examined. Chi‐square tests were conducted to examine group differences for each outcome variable. Group differences were examined between regular foster and non‐foster children, regular foster and ISCEDC children, and regular foster and adoption children.
