✪ Implementation determinants and strategies in integration of PrEP into maternal and child health and family planning services: experiences of frontline healthcare workers in Kenya

Abstract:

Background

Delivery of PrEP to adolescent girls and young women (AGYW) and to pregnant women through maternal and child health (MCH) and family planning (FP) clinics is scaling up in Kenya. Evaluation of implementation challenges and strategies is critical to optimize delivery.

Methods

We conducted focus group discussions (FGDs) with healthcare workers (HCWs) in MCH and FP clinics offering PrEP in a large implementation project in Kisumu, Kenya. Discussion guides were based on the Consolidated Framework for Implementation Research (CFIR). FGDs were audio recorded and transcribed. Directed content analysis was used to identify implementation challenges and strategies to overcome them.

Results

Fifty HCWs from 26 facilities participated in 8 FGDs. HCWs believed PrEP integration was appropriate because it met the needs of AGYW and pregnant women by providing a female-controlled prevention strategy and aligned with policy priorities of elimination of vertical HIV transmission. They were universally accepting of PrEP provision, especially through MCH clinics, noting the relative advantage of this approach because it: (1) enabled high coverage, (2) harmonized PrEP and MCH visits, and (3) minimized stigma compared to PrEP offered through HIV care clinics. However, HCWs noted implementation challenges affecting feasibility and adoption including: (1) increased workload and documentation burden amid workforce shortages, (2) insufficient health care worker knowledge (3) multiple implementing partners with competing priorities (4) drug and documentation form stockouts. HCWs employed various implementation strategies to overcome challenges, including task shifting from nurses to HIV testing providers, patient flow modifications (e.g., fast-tracking PrEP clients to reduce wait times), PrEP demand generation and myth clarification during health talks, provider education, dedicated PrEP delivery rooms, and coordination with adolescent-friendly services. Additional suggested strategies to improve PrEP integration included community education to increase broader PrEP awareness and enable shorter counseling sessions, and task-shifting data entry and client risk assessments.

Conclusions

HCWs were enthusiastic about the appropriateness and acceptability of integrating PrEP services into MCH and FP clinics but noted challenges to adoption and feasibility. Strategies to address challenges focused on improving provider time and space constraints, and increasing provider and client knowledge.

✪ “They are gaining experience; we are gaining extra hands”: a mixed methods study to assess healthcare worker perceptions of a novel strategy to strengthen human resources for HIV in South Africa

Abstract:

Background

Lay health workers (LHWs) can support the HIV response by bridging gaps in human resources for health. Innovative strategies are needed to expand LHW programs in many low- and middle-income countries. Youth Health Africa (YHA) is a novel LHW approach implemented in South Africa that places young adults needing work experience in one-year non-clinical internships at health facilities to support HIV programs (e.g., as HIV testers, data clerks). While research suggests YHA can increase HIV service delivery, we need to understand healthcare worker perceptions to know if this is an acceptable and appropriate approach to strengthen human resources for health and healthcare delivery.

Methods

We conducted a convergent mixed methods study to assess healthcare worker acceptance and perceived appropriateness of YHA as implemented in Gauteng and North West provinces, South Africa and identify issues promoting or hindering high acceptability and perceived appropriateness. To do this, we adapted the Johns Hopkins Measure of Acceptability and Appropriateness to survey healthcare workers who supervised interns, which we analyzed descriptively. In parallel, we interviewed frontline healthcare workers who worked alongside YHA interns and conducted an inductive, thematic analysis. We merged quantitative and qualitative results using the Theoretical Framework of Acceptability to understand what promotes or hinders high acceptance and appropriateness of YHA.

Results

Sixty intern supervisors responded to the survey (91% response rate), reporting an average score of 3.5 for acceptability and 3.6 for appropriateness, on a four-point scale. Almost all 33 frontline healthcare workers interviewed reported the program to be highly acceptable and appropriate. Perceptions that YHA was mutually beneficial, easy to integrate into facilities, and helped facilities be more successful promoted a strong sense of acceptability/appropriateness amongst healthcare workers, but this was tempered by the burden of training interns and limited program communication. Overall, healthcare workers were drawn to the altruistic nature of YHA.

Conclusion

Healthcare workers in South Africa believed YHA was an acceptable and appropriate LHW program to support HIV service delivery because its benefits outweighed its costs. This may be an effective, innovative approach to strengthen human resources for HIV services and the broader health sector.

✪ Adolescent girls and young women’s PrEP-user journey during an implementation science study in South Africa and Kenya

Abstract:

Successful scale-up of PrEP for HIV prevention in African adolescent girls and young women (AGYW) requires integration of PrEP into young women’s everyday lives. We conducted interviews and focus group discussions with 137 AGYW PrEP users aged 16–25 from South Africa and Kenya. Individual and relational enablers and disablers were explored at key moments during their PrEP-user journey from awareness, initiation and early use through persistence, including PrEP pauses, restarts, and discontinuation. PrEP uptake was facilitated when offered as part of an integrated sexual reproductive health service, but hampered by low awareness, stigma and misconceptions about PrEP in the community. Daily pill-taking was challenging for AGYW due to individual, relational and structural factors and PrEP interruptions (intended or unintended) were described as part of AGYW’s PrEP-user journey. Disclosure, social support, adolescent-friendly health counseling, and convenient access to PrEP were reported as key enablers for PrEP persistence.

✪ Process evaluation of PrEP implementation in Kenya: adaptation of practices and contextual modifications in public HIV care clinics

Abstract:

Introduction

In Africa, oral pre-exposure prophylaxis (PrEP) is largely provided via over-burdened public HIV care clinics. Successfully incorporating PrEP services into these clinics may require adaptations to practices outlined in national implementation guidelines and modifications to routine existing service delivery. We aimed to describe adaptations made by public HIV clinics in Kenya to integrate PrEP delivery into existing services.

Methods

The Partners Scale-Up Project aimed to catalyze integration of PrEP in 25 public HIV care clinics. Between May and December 2018, we conducted qualitative interviews with health providers and documented clinic observations in technical assistance (TA) reports to understand the process of PrEP service integration. We analyzed 36 health provider interview transcripts and 25 TA reports to identify clinic-level adaptations to activities outlined in Kenyan Ministry of Health PrEP guidelines and modifications made to existing service delivery practices to successfully incorporate PrEP services. Identified adaptations were reported using the expanded framework for reporting adaptations and modifications (FRAME).

Results

All clinics (n = 25) performed HIV testing, HIV risk assessment, PrEP education and adherence counseling as stipulated in the guidelines. Most clinics initiated clients on PrEP without creatinine testing if otherwise healthy. While monthly refill appointments are recommended, a majority of clinics issued PrEP users two to three months of pills at a time. Clinics also implemented practices that had not been specified in the guidelines including incorporating PrEP-related topics into routine health talks, calling clients with missed PrEP appointments, discussing PrEP service delivery in regular staff meetings, ‘fast-tracking’ PrEP clients and dispensing PrEP in clinic rooms rather than at clinic-based pharmacies. PrEP initiation numbers were highest among clinics that did not require creatinine testing, conducted peer on-the-job PrEP training and those that discussed PrEP delivery in their routine meetings. Above-average continuation was observed among clinics that discussed PrEP in their routine meetings, dispensed PrEP in clinic rooms and offered PrEP at non-regular hours.

Conclusions

Health providers in public HIV care clinics instituted practices and made innovative adaptations to PrEP delivery to reduce barriers for clients and staff. Encouraging clinic level adaptations to national implementation guidelines will facilitate scale-up of PrEP delivery.

✪ Scaling-up PrEP Delivery in Sub-Saharan Africa: What Can We Learn from the Scale-up of ART?

Abstract:

Purpose of Review

Clinical trials have found that PrEP is highly effective in reducing risk of HIV acquisition across types of exposure, gender, PrEP regimens, and dosing schemes. Evidence is urgently needed to inform scale-up of PrEP to meet the ambitious WHO/UNAIDS prevention target of 3,000,000 individuals on PrEP by 2020.

Recent Findings

Successful models of delivering HIV services at scale evolved from years of formal research and programmatic evidence. These efforts produced lessons-learned relevant for scaling-up PrEP delivery, including the importance of streamlining laboratory tests, expanding prescription and management authority, differentiating medication access points, and reducing stigma and barriers of parental consent for PrEP uptake. Further research is especially needed in areas differentiating PrEP from ART delivery, including repeat HIV testing to ensure HIV negative status and defining and measuring prevention-effective adherence.

Summary

Evidence from 15 years of ART scale-up could immediately inform a public health approach to PrEP delivery.

Abstract:

Background

Antiretroviral therapy (ART) for HIV-infected persons and pre-exposure prophylaxis (PrEP) for uninfected persons are extraordinarily effective strategies for HIV prevention. In Africa, the region which shoulders the highest HIV burden, HIV care is principally delivered through public health HIV care clinics, offering an existing platform to incorporate PrEP delivery and maximize ART and PrEP synergies. However, successfully bringing this integrated approach to scale requires an implementation science evaluation in public health settings.

Methods

The Partners Scale Up Project is a prospective, pragmatic implementation evaluation, designed as a stepped-wedge, cluster-randomized trial, operating at 24 clinics in Kenya. In collaboration with the Kenya Ministry of Health, we are catalyzing scaled implementation of PrEP delivery integrated in HIV care clinics. The intervention package includes staff training, clinic streamlined access to PrEP commodity from the Kenya Medical Supply Authority, and ongoing intensive technical assistance to rigorously assess how PrEP delivery is implemented. PrEP service delivery including retention efforts are conducted by the clinic staff with no additional resources from the project. Guided by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework and Consolidated Framework for Implementation Science Research, project progress and learning are documented through ongoing monitoring and process evaluations, including chart abstraction and individual and key informant interviews, to evaluate pragmatic rollout and understand barriers and facilitators for successful PrEP delivery in this setting. In this staged rollout design, each step provides data for both pre-implementation (baseline) and implementation periods, and we will compare time points across steps in the baseline versus implementation periods.

Discussion

Cost-effective delivery models are urgently needed to maximize the public health impact of PrEP and ART. The Partners Scale Up Project will set the stage for full-scale PrEP implementation fully run and owned by the Kenya Ministry of Health. The work combines nationally sponsored PrEP delivery with technical support and implementation science from academic partners, defining a new but sustainable paradigm for public health collaboration.
