Lack of health care worker (HCW) training is a barrier to implementing youth-friendly services. We examined training coverage and self-reported competence, defined as knowledge, abilities, and attitudes, of HCWs caring for adolescents living with HIV (ALWH) in Kenya. Surveys were conducted with 24 managers and 142 HCWs. Competence measures were guided by expert input and Kalamazoo II Consensus items. Health care workers had a median of 3 (interquartile range [IQR]: 1-6) years of experience working with ALWH, and 40.1% reported exposure to any ALWH training. Median overall competence was 78.1% (IQR: 68.8-84.4). In multivariable linear regression analyses, more years caring for ALWH and any prior training in adolescent HIV care were associated with significantly higher self-rated competence. Training coverage for adolescent HIV care remains suboptimal. Targeting HCWs with less work experience and training exposure may be a useful and efficient approach to improve quality of youth-friendly HIV services.

Background: Pregnant and postpartum women in high HIV prevalent regions are at increased HIV risk. Oral pre-exposure prophylaxis (PrEP) can decrease HIV incidence reducing infant HIV infections. Understanding healthcare worker (HCW) beliefs about PrEP prior to national roll-out is critical to supporting PrEP scale-up. Methods: We conducted 45 semi-structured interviews among a range of HCW cadres with and without PrEP provision experience purposively recruited from four clinics in Kenya to compare their views on prescribing PrEP during pregnancy and postpartum. Interviews were analysed using a conventional content analysis approach to identify key influences on PrEP acceptability and feasibility. Results: All HCWs perceived PrEP as an acceptable and feasible HIV prevention strategy for pregnant and postpartum women. They believed PrEP meets women’s needs as an on-demand, female-controlled prevention strategy that empowers women to take control of their HIV risk. HCWs highlighted their role in PrEP delivery success while acknowledging how their knowledge gaps, concerns and perceived PrEP implementation challenges may hinder optimal PrEP delivery. Conclusion: HCWs supported PrEP provision to pregnant and postpartum women. However, counseling tools to address risk perceptions in this population and strategies to reduce HCW knowledge gaps, concerns and perceived implementation barriers are required.

Background: Poor health care worker (HCW) interactions with adolescents negatively influence engagement in HIV care. We assessed the impact of standardized patient actor training on HCW competence in providing adolescent HIV care in Kenya. Methods: We conducted pre-post cross-sectional surveys and qualitative exit interviews during a stepped wedge randomized trial. Cross-sectional surveys assessed self-rated competence in providing adolescent services before and after the intervention, and training satisfaction. In-depth interviews with a subset of HCW participants one year after training. Results: Over 90% of HCWs reported satisfaction with the training and there was significant improvement in self-rated competence scores (mean = 4.63 [highest possible score of 5] post-training vs 3.86 pre-training, p < 0.001). One-year following training, HCWs reported using skills in patient-centered communication and structuring an adolescent clinical encounter. Conclusions: This SP training intervention improved self-rated competence and showed sustained perceived impact on HCW skills in adolescent HIV service provision one year later.

Antiretroviral pre-exposure prophylaxis (PrEP), with daily oral tenofovir disoproxil fumarate or tenofovir disoproxil fumarate in combination with emtricitabine, has been shown to be efficacious for HIV-1 prevention. Although the use of more than one antiretroviral agent is essential for effective HIV-1 treatment, more than one agent might not be required for effective prophylaxis. We assessed the efficacy of single-agent tenofovir disoproxil fumarate relative to combination emtricitabine plus tenofovir disoproxil fumarate as PrEP. We did a randomised, double-blind, placebo-controlled three-group phase 3 trial of daily oral tenofovir disoproxil fumarate and emtricitabine plus tenofovir disoproxil fumarate PrEP in HIV-1 uninfected individuals in heterosexual HIV-1 serodiscordant couples from Kenya and Uganda. After an interim review, the trial's placebo group was discontinued and thereafter the active groups were continued, and participants initially randomly assigned to placebo were offered rerandomisation in a 1:1 ratio to tenofovir disoproxil fumarate or emtricitabine plus tenofovir disoproxil fumarate as PrEP. The primary endpoints were HIV-1 seroconversion and safety. This trial is registered with ClinicalTrials.gov, number NCT00557245. 4410 (99·6%) of 4427 couples received tenofovir disoproxil fumarate or emtricitabine plus tenofovir disoproxil fumarate and were followed up for HIV-1 acquisition. Of 52 incident HIV-1 infections, 31 occurred in individuals assigned tenofovir disoproxil fumarate (incidence 0·71 cases per 100 person-years) and 21 were in those assigned emtricitabine plus tenofovir disoproxil fumarate (0·48 cases per 100 person-years); HIV-1 incidence in the placebo group until discontinuation was two cases per 100 person-years. HIV-1 prevention efficacy with emtricitabine plus tenofovir disoproxil fumarate was not significantly different from that of tenofovir disoproxil fumarate alone (hazard ratio [HR] 0·67, 95% CI 0·39–1·17; p=0·16). Detection of tenofovir in plasma samples, compared with no detection and as measured in seroconverters and a subset of non-seroconverters, was associated with an 85% relative risk reduction in HIV-1 acquisition for the tenofovir disoproxil fumarate group (HR 0·15, 95% CI 0·06–0·37; p<0·0001) and 93% for the emtricitabine plus tenofovir disoproxil fumarate group (0·07, 0·02–0·23; p<0·0001). No significant differences were noted in the frequency of deaths, serious adverse events, or serum creatinine and phosphorus abnormalities between the two groups. These results do not rule out the potential for a slight difference in HIV-1 protection with tenofovir disoproxil fumarate compared with emtricitabine plus tenofovir disoproxil fumarate, but show that once-daily oral tenofovir disoproxil fumarate or emtricitabine plus tenofovir disoproxil fumarate regimens both provide high protection against HIV-1 acquisition in heterosexual men and women.
