Objectives

• Provide overview of Implementation Science Research approach and methods

• Overview of PEPFAR Implementation Science initiative

• Introduce ICAP’s new Implementation Science studies– Describe, in greater depth, a subset of these

studies

Page 3: Implementation Science Elaine Abrams, MD Senior Research Director.

What is Implementation Research? • ‘Research to promote the uptake & successful implementation

of evidence-based interventions and policies’ (Sanders)

• ‘Evidence that informs effective, sustained & embedded adoption of interventions by health systems & communities’ (Allottey)

• ‘All aspects of research relevant to the scientific study of methods to promote the uptake of research findings into routine settings in clinical, community and policy contexts’

• ‘Research to significantly improve access to efficacious interventions by developing practical solutions to common implementation problems’ (WHO)

• ‘Scientific study of methods to promote the systematic uptake of research findings & evidence-based practices into routine practice, to improve the quality and effectiveness of health’

Sanders et al, PLOS Med, 3:e186; Allottey et al, BMC Pub Health 8:343, WHO; Remme et al, PLOS Med Nov 2010

Page 4: Implementation Science Elaine Abrams, MD Senior Research Director.

Implementation Research• ‘Implementation research aims to develop new

strategies for available or new health interventions in order to improve access to, and the use of, these interventions by the populations in need’ (Remme)

• Seeks to address the “know-do gap’ – why and how best to successfully implement evidenced based interventions

Remme et al, PLOS Med Nov 2010

Page 5: Implementation Science Elaine Abrams, MD Senior Research Director.

• IR tests practical solutions to service delivery and challenges in order to– Address problems specific to a health system or

environment or those that are common to a particular region

– Identify how evidence-based interventions, tools, and services should be modified to achieve sustained health impacts in real-world settings

– Determine the best way to introduce practical solutions into health systems and facilitate full-scale implementation, evaluation, modification

Implementation Research

Page 6: Implementation Science Elaine Abrams, MD Senior Research Director.

• IR uses contextual knowledge to study processes to improve practice

• IR applies research findings and methods to real-world contexts and settings

• IR places particular emphasis on access to efficacious interventions, service delivery models, feasibility of interventions in different settings

• The outcome of a successful IR project is integration of findings into practice or policy

Implementation Research

Page 7: Implementation Science Elaine Abrams, MD Senior Research Director.

Characteristics of Implementation Research

• Systematic– Adheres to norms of scientific inquiry– Specific intervention, specific setting– Balances relevance with rigor

• Multidisciplinary– Considers biological, social, economic, political,

system and environmental factors that impact implementation

– Collaborations between behavioral and social scientists, clinicians, epidemiologists, statisticians, policy makers, stakeholders

Page 8: Implementation Science Elaine Abrams, MD Senior Research Director.

Characteristics of Implementation Research (continued)

• Contextual– Relevant to local circumstances and need– Generates generalizable knowledge that can be

applied across contexts• Complex

– Dynamic and adaptive– Occurs at multiple levels of health care system,

community– Analyzes multi-component programs

PEPFAR Implementation Science Model

• PEPFAR implements scientific advances on a large scale through its programs

• PEPFAR has shifted towards an Implementation Science model as the scientific framework to guide program implementation and scale-up that focuses on effectiveness and efficiency to build the evidence base necessary to inform the best approaches to achieve sustainable prevention, care and treatment programs

Page 12: Implementation Science Elaine Abrams, MD Senior Research Director.

PEPFAR Implementation Science Model & Initiative

• Current Implementation Science efforts include a range of funded evaluation activities including:– Implementation Science (IS) Awards– Basic Program Evaluations (BPE)– Impact Evaluations (IE)

• PEPFAR created a $60 million dollar initiative to support Implementation Science Research to evaluate PEPFAR programs. – The Initiative was funded through collaborations

with the CDC, NIH and USAID

Page 13: Implementation Science Elaine Abrams, MD Senior Research Director.

ICAP’s ‘won’ 7 Implementation Science Awards

• USAID funded – Engage4Health (Ligações pela saúde), Mozambique – Safe Generations (Situkulwane Lesiphephile), Swaziland – START (Start TB patients on ART and Retain on Treatment),

Lesotho

• NIH funded – LINK4HEALTH, Swaziland– MCH-ART, South Africa– MIR4Health (Mother-Infant Retention for Health), Kenya– ENRICH (Enhance Initiation and Retention in IPT Care for HIV),

Ethiopia

Page 14: Implementation Science Elaine Abrams, MD Senior Research Director.

ICAP’s Implementation Science Studies

• 7 different countries in Sub Saharan Africa• Represent productive collaborations between PI, NY

teams, and country teams• Address several key clinical domains: adult ART

linkage and retention, TB treatment and prevention IPT, and PMTCT including maternal and infant health

• Encompass a variety of scientific approaches, methodologies, patient populations, outcomes

• All grow out of the programmatic work leading to critical implementation questions around how best to successfully implement evidenced based interventions

SAFE GENERATIONSSITUKULWANE LESIPHEPHILE

• Partnership in the Kingdom of Swaziland between:– MOH(Sexual and Reproductive Health Unit (SRHU)

and Swaziland National AIDS Program (SNAP)– ICAP– University of Cape Town – Elizabeth Glazer Pediatric AIDS Foundation– NERCHA

Page 17: Implementation Science Elaine Abrams, MD Senior Research Director.

Background • There is sound scientific evidence on the efficacy of ARV

interventions during pregnancy, delivery and breastfeeding and enormous PMTCT success in high resource settings with MTCT rates ~ 1-2%

• However, despite major advances in PMTCT interventions in 2011, there were ~ 330,000 new pediatric infections worldwide, 90% of them attributable to MTCT.1,3

• Swaziland is currently implementing WHO ‘Option A’*– Lifelong treatment for ART-eligible women– Prophylaxis for non-eligible women: AZT from 14 weeks’ gestation

with sd-NVP at delivery plus a 7-day tail of twice daily AZT and 3TC postpartum, and daily NVP to the infant during breastfeeding

• Substantial implementation challenges have been encountered

*WHO Option B: lifelong ART for eligible women and triple ARV prophylaxis during pregnancy and breast feeding

Page 18: Implementation Science Elaine Abrams, MD Senior Research Director.

Maternal PMTCT Cascade, Swaziland, 2011

Page 19: Implementation Science Elaine Abrams, MD Senior Research Director.

Infant PMTCT Cascade Swaziland, 2011

Page 20: Implementation Science Elaine Abrams, MD Senior Research Director.

Testing a New Strategy for PMTCT

• The country of Malawi adopted a new strategy for PMTCT – Option B+ : lifelong ART for all pregnant and breast feeding women

• Recognizing the complexity of Option A and considerable implementation challenges encountered in the field, WHO recently endorsed Options B+ and outlined considerable programmatic and implementation advantages of this approach

• However, there are limited data on Option B+ implementation and/or comparisons with other approaches

• The Swaziland MOH reluctant to adopt new approach without strong evidence of benefit

Page 21: Implementation Science Elaine Abrams, MD Senior Research Director.

SITUKULWANE LESIPHEPHILE SAFE GENERATIONS: OBJECTIVES

• Primary Objective: To compare the impact of implementing Option A and Option B+ on the composite endpoints of infant HIV positive DNA PCR OR maternal loss to follow-up (LTFU) 6 months postpartum

• Secondary Objectives: To compare Option A and Option B+:

– Cost effectiveness– Patient and provider acceptability– Proportion of pregnant women CD4+<350 cells/mm3 who start ART– Proportion of women retained in HIV care at 12, and 18 months

postpartum

Page 22: Implementation Science Elaine Abrams, MD Senior Research Director.

SITUKULWANE LESIPHEPHILE SAFE GENERATIONS: STUDY HYPOTHESIS

Option B+: integration of prevention and treatment into a uniform and streamlined treatment and retention approach modified for the continuum of perinatal maternal-child care will:

– Result in higher proportion of mother-child pairs completing the PMTCT cascade

– Fewer paediatric infections – Lead to higher proportion of women with CD4+<350

initiating ART earlier in pregnancy– Be more acceptable to staff and clients– Be more feasible and more cost-effective

Page 23: Implementation Science Elaine Abrams, MD Senior Research Director.

SITUKULWANE LESIPHEPHILE SAFE GENERATIONS: STUDY COMPONENTS

• This study is comprised of three study components: 1) Option B+ evaluation 2) Acceptability evaluations with PMTCT clients and

health care workers3) Cost-effectiveness analysis

Page 24: Implementation Science Elaine Abrams, MD Senior Research Director.

Study Design: Option B+ Intervention Evaluation

• Stepped wedge design: One facility per month will transition from Option A to Option B+ (total 10 facilities)

• Estimated 2,700 women enrolling into care during study period Month 1 2 3 4 5 6 7 8 9 10 11 12

Outcome Measurements: Option B+ Evaluation (1)

• PMTCT (A and B+) will be provided as standard of care at study sites. Women will be consented to allow chart review and abstraction of health records (for mom and baby)

• Primary outcome: Combined maternal-child endpoint at 6 months post partum of:– Infant HIV PCR positiveOR– Mother Lost To Follow-Up

Page 26: Implementation Science Elaine Abrams, MD Senior Research Director.

Outcome Measurements: Option B+ Evaluation (2)

• Secondary outcomes:– Proportion of pregnant women with CD4+<350 initiating ART

during pregnancy – Duration of ART received prior to delivery for ART-eligible

pregnant women– Proportion of women and children retained in HIV care at 12,

and 18 months postpartum– Birth outcomes (birth weight, SGA, gestation age)– Infant feeding practices– Maternal health outcomes

Page 27: Implementation Science Elaine Abrams, MD Senior Research Director.

Outcome Measurements: Option B+ Acceptability

• Interviews with PMTCT clients will focus on:– PMTCT and ART knowledge and beliefs– Barriers to PMTCT services– Perception of women’s uptake of services– Quality of care that the receive

• Interviews with HCWs will focus on:– Barriers to PMTCT implementation– Understanding and attitude towards B+

intervention– Perceptions of PMTCT client uptake

Page 28: Implementation Science Elaine Abrams, MD Senior Research Director.

Outcome Measurements: Option B+ Cost Effectiveness Assessment

• Cost-effectiveness assessment will be lead by UCT collaborators– Data on unit costs including human resources costs will be abstracted

from the following sources:• Routine facility and MOH accounts• Facility utilization data and staffing plans, and pharmacy accounts maintained

by the MOH

– Data on service utilization by participants will come directly from the evaluation

– Program costs will be based on local standards for training and materials development

– Outcome data will be used to calculate the incremental cost required to improve patient outcomes of infant HIV PCR positivity, maternal retention, and their combination, all assessed at 6 months postpartum.

StartTB patients onART andRetain onTreatment

Page 30: Implementation Science Elaine Abrams, MD Senior Research Director.

Background and Rationale

• TB is a leading cause of death, accounts for nearly a quarter of HIV-related deaths worldwide

• Early initiation of ART during TB treatment significantly increases AIDS-free survival by 34-68%1-3

• In the African Region only 42% of TB patients were on ART in 2010– In Lesotho it was as low as 27% in 2010

1Karim 2011; 2Havlir 2011; 3Blanc 2011

Page 31: Implementation Science Elaine Abrams, MD Senior Research Director.

Background & Rationale (2)• Barriers to early ART initiation and

retention include:– Health Care Workers

• Lack knowledge about benefits of early ART, guidelines for TB/HIV co-management (adverse events, IRIS)1,2

– Patients• Unaware of importance of early ART during TB

treatment3

• Fear of toxicity, side effects, death, concerns about pill burden3,4

• Lack funds for transportation to clinic1,3,5,6

• Lack social and family support4,5

• Urgent need to identify programmatic interventions that address these barriers to implementation

Page 41: Implementation Science Elaine Abrams, MD Senior Research Director.

Background and Rationale

• IPT reduces TB risk by 33% overall, by 64% if TST+, in absence of ART1

• IPT reduces risk of death during early ART2

• IPT + ART results in greater reduction in TB risk than either alone3,4

• ~180,000 PLWH received IPT in 2010 (12% of 1.5 million PLWH newly enrolled in HIV care)5

• ProTEST project: IPT completion 24%-59%6

Page 42: Implementation Science Elaine Abrams, MD Senior Research Director.

Background & Rationale (2)• Barriers to IPT implementation include:

– Health Care Workers• Lack of knowledge/clarity on IPT benefits,

guidelines1,2 • Concern about toxicity, resistance, inadequate

adherence1,2,3

– Programs• Lack SOPs to assess IPT eligibility, monitoring for

AEs, adherence1,3

– Patients• Lack funds for transportation to clinic2,4

• Lack social and family support4,5

• Beliefs about IPT efficacy, side effects5

• Urgent need to identify programmatic interventions that address these barriers to implementation

Page 43: Implementation Science Elaine Abrams, MD Senior Research Director.

Study AimsSpecific Aim 1: • Characterize and compare the effectiveness of

CIP with SOC for IPT provision in Ethiopia– IPT initiation– IPT adherence– IPT completion

Specific Aim 2:• Assess the impact of CIP compared with SOC

on HIV-related outcomes– Retention in care– ART adherence– CD4+ count

Page 44: Implementation Science Elaine Abrams, MD Senior Research Director.

Study Aims (2)

Specific Aim 3:• Assess safety and tolerability of IPT

among HIV-infected individuals under routine program conditions

Specific Aim 4:• Identify patient and program

characteristics associated with IPT adherence and completion at SOC sites

Page 45: Implementation Science Elaine Abrams, MD Senior Research Director.

Study Design

• Two-arm cluster randomized trial, randomized at the HIV clinic level

• Ten HIV clinics at health centers in Dire Dawa and Harari, Ethiopia

• Clinics randomized to deliver CIP or SOC– Stratification by clinic size

Interactive Voice Response Messaging

• Prepaid mobile phones for patients starting IPT – Low mobile phone penetration

• Interactive Voice Response calls in local languages– Low literacy rate– PIN to protect confidentiality– Medication and appointment adherence

reminders– Call schedule tailored to patient’s

preferences– Monitoring messages to assess

adherence, side effects– Peer educators follow-up with patients

with difficulties

Page 48: Implementation Science Elaine Abrams, MD Senior Research Director.

Study Participants

• All new HIV patients eligible for IPT (~1120)

• Measurement cohort of IPT initiators (with 6-9 months follow up)– CIP (n=250)– SOC (n=250)
