Abstract:

The World Health Organization recommends differentiated service delivery (DSD) models for HIV prevention, including alternatives to clinic-based PrEP services. This study assessed the acceptability and feasibility of remote PrEP delivery—including HIV and pregnancy self-testing, and phone-based adherence counselling—among adolescent girls and young women (AGYW) in Johannesburg. The research was nested within the PrEP SMART trial (2019–2022), which evaluated scalable adherence support strategies for AGYW aged 18–25. During COVID-19 lockdowns, PrEP refills and testing kits were delivered to participants’ homes, and counselling was provided by phone. Using a phenomenological qualitative method, we conducted in-depth interviews with AGYW (n = 14) who had the option to complete remote PrEP visits (accepting or declining), study staff (n = 12), and key informants (n = 10) involved in PrEP programming. Thematic analysis explored experiences of remote delivery, focusing on acceptability and feasibility.

AGYW found remote PrEP visits convenient, empowering, and time-saving. Procedures such as self-testing and phone counselling were generally acceptable, though some expressed anxiety about performing tests incorrectly and concerns over privacy, stigma, and unintentional disclosure of PrEP use at home. About half still preferred clinic-based visits. Staff and key informants recognized benefits, but highlighted challenges related to cost, sustainability, and provider workload. Suggestions for improvement included integrating contraception and partnering with community organizations. In conclusion, remote PrEP delivery is acceptable and feasible for many AGYW but not universally suitable. These findings support the inclusion of remote PrEP options in DSD models, with attention to privacy concerns and support for self-testing in this age group.

Abstract:

Background

Clinical treatment guidelines are designed to improve quality of care by offering clear recommendations for health workers; however, across many settings, implementing guidelines is a challenge. For over 20 years, comprehensive World Health Organization guidelines for care of hospitalized children have provided guidance for treating the primary causes of childhood death. These recommendations were adapted in Kenya and codified in the Basic Paediatric Protocol; however, adherence to these evidence-based interventions remains suboptimal.

Methods

This qualitative study identified the barriers and facilitators of providing guideline-adherent care to children admitted to two hospitals in Kenya. The semi-structured question guide was informed by the Theoretical Domains Framework (TDF). Three focus group discussions and 16 in-depth interviews were conducted with 35 health workers. Participants were nurses, doctors, clinical officers, or nutritionists (including in-charges and clinical supervisors). Interviews were audio recorded and transcribed. Transcripts were coded using a TDF-based codebook, validated, and analyzed for themes.

Results

TDF domains with the greatest influence on the thematic findings were environmental context and resources, social influences, beliefs about consequences, and beliefs about capabilities. Health workers were knowledgeable about guidelines and felt strongly that adherence to them was beneficial; however, they also faced barriers implementing them. Challenges related to the environmental context were pervasive, including shortages of staff and supplies. Participants praised the simplicity of guidelines but also noted that simplified diagnostic criteria don’t align with complex patient presentations. While guidelines empowered some nurses to make clinical decisions, respondents reported that strict professional roles sometimes delayed diagnosis and treatment. Further, health workers reported some deviations were intentional (ex. when guidelines were not aligned to their beliefs) and other times they were unintentional (ex. when complex patient presentations make guideline adherence difficult).

Conclusions

Knowledge of guidelines and motivation to use them were not major determinants in this analysis. Rather, human and material resource shortages presented the greatest barrier to guideline adherence in this setting. Improving guidelines by involving health workers in participatory development of guidelines would improve both clarity and feasibility. Health workers are well-versed in guideline recommendations, so educational strategies should focus on knowledge gaps or changes in the latest version of guidelines.

Abstract:

Background

Despite being at elevated risk for HIV, men who have sex with transgender women (MSTW) are an overlooked population in the global HIV response. Venue-based HIV interventions have previously had success reaching other HIV priority populations, including transgender women (TW). Similar approaches could be applied for MSTW.

Objective

To evaluate the prospective acceptability of venue-based HIV testing and prevention interventions for MSTW and TW in Lima, Peru.

Methods

In this exploratory qualitative study, we conducted in-depth interviews (IDI) and focus group discussions (FGD) with three types of participants: MSTW (7 IDIs, 1 FGD), TW (1 FGD), and owners of social venues frequented by MSTW/TW in Lima (2 IDIs). We elicited participants’ attitudes and perceptions related to the following four hypothetical interventions delivered at social venues in Lima: rapid HIV testing; HIV self-test distribution; condom/lubricant distribution; and enrolment in a mobile app supporting HIV prevention. We performed a mixed deductive-inductive thematic analysis using the framework method, then applied the Theoretical Framework of Acceptability to classify the overall acceptability of each intervention.

Results

Condom/lubricant distribution and app-based HIV prevention information were highly acceptable among all participant types. The two HIV testing interventions had relatively lower acceptability; however, participants suggested this could be overcome if such interventions focused on ensuring discretion, providing access to healthcare professionals, and offering appropriate incentives.

Conclusions

Overall, MSTW and TW shared similar favourable attitudes towards venue-based HIV interventions. Venue-based outreach warrants further exploration as a strategy for engaging MSTW and TW in HIV prevention activities.
