Integrating pre-exposure prophylaxis of HIV infection into family planning services: a scoping review

Barriers and facilitators to uptake and use of oral pre-exposure prophylaxis in pregnant and postpartum women: a qualitative meta-synthesis

BACKGROUND

Acute HIV infection during pregnancy and in the postpartum period increases the risk of vertical transmission. The World Health Organization (WHO) has recommended preexposure prophylaxis for pregnant and postpartum women at risk of acquiring HIV. However, there are significant gaps between the actual practice and the ideal goal of preexposure prophylaxis implementation among pregnant and postpartum women. Therefore, it is important to determine what influences women's implementation of preexposure prophylaxis during pregnancy and in the postpartum period. This review aims to aggregate barriers and facilitators to preexposure prophylaxis implementation among pregnant and postpartum women.

METHODS

A range of electronic databases, including PubMed, CINAHL Plus with Full Text, Embase, and Web of Science, were searched for potentially relevant qualitative studies. The search period extended from the establishment of the databases to March 16, 2023. This review used the ENTREQ (Enhancing transparency in reporting of qualitative research synthesis) statement to guide the design and reporting of qualitative synthesis. The methodological quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The JBI meta-aggregation method was applied for guiding the data extraction, and the JBI ConQual method was applied for guiding the evaluation of the level of evidence for the synthesis.

RESULTS

Of retrieved 2042 studies, 12 met the inclusion criteria. The total population sample included 447 participants, including 231 pregnant and postpartum women, 21 male partners, 75 healthcare providers (HCPs)/healthcare workers (HCWs), 18 policymakers, 37 mothers, and 65 women of childbearing age. A total of 149 findings with credibility ratings of "unequivocal" or "equivocal" were included in this meta-synthesis. Barriers and facilitators to preexposure prophylaxis implementation were coded into seven categories, including three facilitator categories: perceived benefits, maintaining relationships with partners, and external support, and four barriers: medication-related barriers, stigma, barriers at the level of providers and facilities, and biases in risk perception.

CONCLUSION

This systematic review and meta-synthesis aggregated the barriers and facilitators of preexposure prophylaxis implementation among pregnant and postpartum women. We aggregated several barriers to maternal preexposure prophylaxis implementation, including medication-related factors, stigma, barriers at the level of providers and facilities, and risk perception biases. Therefore, intervention measures for improving preexposure prophylaxis services can be developed based on these points.

Structural influences on delivery and use of oral HIV PrEP among adolescent girls and young women seeking post abortion care in Kenya

Background

Adolescent girls and young women (AGYW) in East and southern Africa experience a disproportionate burden of HIV incidence. Integrating HIV pre-exposure prophylaxis (PrEP) within existing programs is a key component of addressing this disparity.

Methods

We evaluated an oral PrEP program integrated into post-abortion care (PAC) in Kenya from March 2021 to November 2022. Technical advisors trained staff at PAC clinics on PrEP delivery, abstracted program data from each clinic, and collected data on structural characteristics. Utilizing a modified Poisson regression, we estimated the effect of structural factors on the probability of PrEP offer and uptake.

Findings

We abstracted data on 6877 AGYW, aged 15-30 years, across 14 PAC clinics. PrEP offers were made to 57.4% of PAC clients and 14.1% initiated PrEP. Offers were associated with an increased probability at clinics that had consistent supply of PrEP (relative risk (RR):1.81, 95% CI: 1.1-2.95), inconsistent HIV testing commodities (RR: 1.89, 95% CI: 1.29-2.78), had all providers trained (RR: 1.65, 95% CI: 1.01, 2.68), and were public (RR: 1.89, 95% CI: 1.29-2.78). These same factors were associated with PrEP uptake: consistent supply of PrEP (RR: 2.71, 95% CI: 1.44-5.09), inconsistent HIV testing commodities (RR: 2.55, 95% CI: 1.39-4.67), all providers trained (RR: 2.61, 95% CI: 1.38-4.92), and were public (RR: 2.55, 95% CI: 1.39-4.67).

Interpretation

Greater success with integration of HIV prevention into reproductive health services will likely require investments in systems, such as human resources and PrEP and HIV testing commodities, to create stable availability and ensure consistent access.

An implementation strategy package (video education, HIV self-testing, and co-location) improves PrEP implementation for pregnant women in antenatal care clinics in western Kenya

Background

Pre-exposure prophylaxis (PrEP) is recommended by the World Health Organization and the Kenyan Ministry of Health for HIV prevention in pregnancy and postpartum for women at risk for HIV. Integration of PrEP into antenatal care is promising, but delivery gaps exist in the face of healthcare provider shortages in resource-limited settings.

Methods

Between May and November 2021, we conducted a difference-in-differences study (3 months pre-intervention data collection and 3 months post-intervention data collection) analyzing four intervention facilities, where the strategies were implemented, and four comparison facilities, where no strategies were implemented. We tested a combination of three implementation strategies-video-based PrEP information in the waiting bay, HIV self-testing, and dispensing of PrEP in the antenatal care rooms-to improve PrEP delivery. We compared absolute changes in the proportion of antenatal attendees screened for PrEP (PrEP penetration), the proportion receiving all PrEP-specific steps in a visit (HIV testing, risk screening, and PrEP counseling) (PrEP fidelity), and client PrEP knowledge, client satisfaction, and waiting time and service time (a priori outcomes); post hoc, we compared the proportion offered PrEP (PrEP offer) and completing HIV testing. We measured provider perceptions of the acceptability and appropriateness of the implementation strategies.

Results

We observed significant improvements in PrEP penetration, PrEP offer, satisfaction, and knowledge (p < 0.05) and improvements in fidelity that trended towards significance (p = 0.057). PrEP penetration increased 5 percentage points (p = 0.008), PrEP fidelity increased 8 percentage points (p = 0.057), and PrEP offer increased 4 percentage points (p = 0.003) in intervention vs. comparison facilities. Client PrEP knowledge increased by 1.7 out of 6 total points (p < 0.001) and client satisfaction increased by 0.7 out of 24 total points (p = 0.003) in intervention vs. comparison facilities. We observed no changes in service time (0.09-min decrease; p = 0.435) and a small increase in waiting time (0.33-min increase; p = 0.005). HIV testing among those eligible did not change (1.5 percentage point decrease, p = 0.800). Providers felt the implementation strategies were acceptable and appropriate (median acceptability: 20/20; median appropriateness: 19.5/20). However, absolute levels of each step of the PrEP cascade remained suboptimal.

Conclusions

An implementation strategy package with video information, HIV self-testing, and co-location of medication dispensing enhanced PrEP delivery across several implementation outcomes and client satisfaction, while not substantially increasing wait time or decreasing provider-client contact time.

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

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.
