Prescription Drug Poisoning: No Longer A Silent Epidemic
Christy Porucznik, PhD MSPH
Utah Health Status Update:August 2007
Poisonings surpass motor vehicle crashes as Utah’s leading cause of injury death.
In 2003, rate of unintentional and undetermined intent poisoning deaths, 13.9 per 100,000, surpassed that for motor vehicle crash, 13.2 per 100,000.
The increase has continued and the gap is widening.

National Status, 2014
41,340 deaths
16,917 deathsNearly 4x increase since 1999
Death Certificates as a Data Source
• Underlying causes of death classified using ICD-10 and selected by the drug poisoning codes
• X40: Accidental poisoning by and exposure to non-opioid analgesics, antipyretics and antirheumatics
• X42: Accidental poisoning by and exposure to narcotics and psychodysleptics [hallucinogens], not elsewhere classified
• X60: Intentional self-poisoning by and exposure to nonopioid analgesics, antipyretics and antirheumatics
US Death Certificates: Consider Age
• Specific drugs noted in the T codes based upon autopsy findings– T40.2: natural and semisynthetic opioid analgesic– T40.3: methadone– T40.4: synthetic opioid analgesic, excluding
methadone– T42.4: benzodiazepines
• In 2011, 25% of drug-poisoning deaths did not include any specific drugs– T50.9: unspecified, drug-related
US Death Certificates: Categories of Analgesics
Utah Medical Examiner Database
US Death Certificates: Benzodiazepines and Opioids
2004: Where we began…• Medical Examiner noticed more deaths caused
by prescribable drugs, asked epidemiologist to take a look at the data
• Using Medical Examiner data– Centralized, statewide medical examiner
• Reviewed all drug poisoning deaths between 1991 and 2003– Categorized by type of drug involved

Increase in Number of Methadone-Related Deaths
• Office of the Medical Examiner case files for methadone-related deaths
• Year 2000 on the left, 2004 on the right
Questions• Was this a patient
safety problem?
• Was this a law enforcement problem?
• Was it both?
PMP: Utah Controlled Substances Database (CSD)
• Maintained by Division of Occupational and Professional Licensing (Commerce)
• Registry of all prescriptions for Schedule II-V drugs dispensed in Utah and by Utah providers.
• Worked with the legislature to change the law and rules so that data could be used for research by the Department of Health
Using administrative data for research
• The CSD was never intended for research• The first users to try and analyze it in
aggregate• Much data cleaning• Very large dataset, long computer runtime • Lacks a unique patient identifier, so we used a
combination deterministic-probabilistic algorithm to create individual patient histories
First Linking of ME to PMP (2006)
• 47% had an active opioid Rx at time of death– 57% filled within 30 days of death, – 63% within 90 days of death, and 75% within 365
days of death. • No evidence of a filled opioid prescription
from 1999 through the date of death for only 15% of these decedents
• 43% had an active Rx for every drug identified on toxicology at time of death

HB 137: Legislative ChargeJuly 2007-2009
• Research– Causes, risk factors, solutions
• Create Guidelines• Educate
– Health Care Providers– Patients– Insurers– General Public
Mean Annual ED Visits Per Patient by Year and Patient Type
Enhanced ME Investigation• Interviews were conducted for Utah residents
ages 12+ who died from drug-related causes between October 26, 2008-October 25, 2009.

• 87.4% of decedents had taken prescription pain medication within 1 year of deathReporting all sources– 91.8% from healthcare provider– 24% free from a friend or relative– 18.2% stolen– 16.4% purchased from a friend or relative– 11.6% purchased from a drug dealer
• Among decedents taking medication prescribed by a healthcare provider– 52.9% took more than prescribed– 42.4% had visited multiple doctors to get
medications– 29.8% used pain medications for other reasons
• Recreational use, 48.4%• Self-medication for depression, 25.0%; anxiety, 15.6%;
or sleep, 4.6%
Social Characteristics
Decedents• In the 2 months prior to death

Comparison Population• Utah: 61.4% employed• U.S. males & females
– 82.0% & 73.0% employed• 14.3% U.S. adults in poverty• 83.3% U.S. adults insured
• 32.0% U.S. adults complex activity limitation
BRFSS: Medically Unsupervised Use of Prescription Pain Drugs
• 12 questions added to 2008 BRFSS• 5,330 respondents (ages 18+)• 20.8% prescribed opioid pain drug in previous
year– 3.2% used own Rx more frequently or in higher
doses than prescribed– 72% had leftover medication
• 71% kept the leftover medication
BRFSS Results• 1.8% of respondents reported using
prescription opioids not prescribed to them• Corresponds to 34,637 Utah adults• 97% received it from a friend or relative
– 85.2% free or as a gift– 9.8% took it without the person’s knowledge
Education: Patients & General Public
• Media Campaign Jan 2008-June 2009– Public Opinion Survey– Collateral materials– Prescription Awareness Week (end of October)– Contracted with Vanguard Media
Initial Research for Media Campaign• 3 Focus Groups
• Statewide telephone survey– Key Findings (among 23 of 29 counties)
• Doctors and pharmacies are primary sources of information about medication
• Most people have NOT seen information about prescription pain medications at doctors offices or pharmacies
Television

Collateral materials
Print advertisements
Community events and displays
Coverage in the news media
Tracking hits to the website
Media Campaign Post Survey Results• Research Results
– 48% of Utah residents recall seeing the commercial• Majority (62%) saw it more than 5 times
– 34% said media messages made them a “Great Deal” more aware (53% at least somewhat)
– 35% had seen information at doctor’s office– 32% had seen info at pharmacy
Utah Clinical Guidelines on Prescribing Opioids
• Based on 7 evidence-based guidelines • Utah consensus product• Mandated by legislature• Accompanied by implementation tools
Guidelines
• Aimed at providers who prescribe opioids for the treatment of pain
• Summary and Full versions available• Available for free by request or online at:
Useonlyasdirected.org
Provider Education
• 30 small group trainings– 6-10 doctors– Required homework – Evaluation of behavior change– Follow up surveys (Up to 20 CME credits)
• 10 large group presentations– 5 CME’s
• Mailings/Articles
Continuing Research• Survey providers, have they changed?
• Using the CSD data to examine changes in prescribing– Evaluate impact of Utah Clinical Guidelines on
Prescribing Opioids
Provider Survey• Report that they lack
– Sufficient training to feel confident prescribing opioids
– Referral resources• Use screening tools that are incorporated into
the electronic medical record, not external tools
• Do not enjoy treating patients with chronic, non-malignant pain

UDOH received funding forprescription pain medicationeducation and research
2014 data are preliminary
Funding eliminated
• Mandates that providers must register with online query system in order to renew their controlled substance prescribing license– Does not require providers to use the system
• Passed in March• Licenses expire in June• Must register by September 30
Utah HB 28 (2010)
1. Did the implementation of HB28 result in increased provider utilization of the Controlled Substances Database (CSD) online system?
Can study this using the log file associated with the online system
first use of these data!
Research Questions
System use has increased
H.B. 28 passed, March 2010
H.B. 28 takes effect, September 2010
Whose fault is this anyway?
• Pain specialists point fingers to primary care• Primary care points right back
• Primary care writes majority of prescriptions• Specialties, including pain medicine,
associated with more fatalities than we would expect based on their prescribing
Physician Specialty and ADE
• Used our file which links the CSD to the medical examiner data
• Attached physician specialty to each rx using information from the NPI
• Deaths were assigned to every provider who had written a prescription for the decedent which was active at the time of death
Evaluating Impact: Utah Clinical Guidelines on Prescribing Opioids• Not a simple task• Classified individual patients by user type
– Acute– Intermittent– Chronic
• Created indicator flags for guideline violations based on data available in CSD

PMP: Lessons Learned• Helpful to have unique identifier to create
individual prescription histories (we don’t have this)
• Ongoing data quality verification important to maintain integrity and utility of data
• Providers need to know that the data are timely and accurate
What do we wish for?• Indicator variable for veterinary prescriptions• Physician specialty in the PMP• Information about group practices in the PMP
– and mid-levels associated with providers• Ability to link PMP with medical records
– Diagnosis– Other, non CS prescriptions
The future?• Bi-directional communication for providers
with the PMP– What happens when they query?– Ability for provider to insert a red flag onto a
patient record in the PMP• More use of PMP for systematic monitoring of
community-level indicators• Aberration detection in real time
