    BACKGROUND: There are over 23 000 incarcerated people in Zambia, a population which has higher HIV prevalence than the general population yet has no access to HIV prevention. To evaluate the feasibility of HIV pre-exposure prophylaxis (PrEP) implementation in Zambian criminal justice facilities, we offered PrEP services to incarcerated people and aimed to describe early implementation outcomes. METHODS: In this cross-sectional observational study, we implemented a PrEP programme between Oct 1, 2020, and March 31, 2021, supporting 16 criminal justice facilities in four Zambian provinces. Before implementation, we held stakeholder engagement meetings with Zambia Correctional Service officials to discuss PrEP benefits, and trained Zambia Correctional Service health-care workers in PrEP management using the national PrEP training package. People who were incarcerated and screened positive for substantial HIV risk by use of a standardised HIV risk assessment tool were offered voluntary HIV testing and counselling. Those who tested positive were linked to antiretroviral therapy, and those who tested negative and met national HIV prevention eligibility criteria were offered PrEP. We assessed PrEP uptake and used descriptive statistics to characterise programme beneficiaries and the cascade of PrEP services. FINDINGS: During the study period, we reached 12 367 people older than 15 years with HIV risk assessment and counselling, including 11 794 (95·4%) men and 573 (4·6%) women. Of these, 2610 people received HIV testing, with 357 (13·7%) testing HIV positive; positivity was significantly higher in women (20·6%) than men (13·2%, p=0·011). 1276 people were identified as HIV negative and PrEP eligible. Of these, 1190 (93·3%) initiated PrEP. The age group with the highest proportion reached and initiated on PrEP was those aged 25-29 years, representing 19·2% (2377 of 12 367) of all people reached and 24·1% (287 of 1190) of those who initiated PrEP. INTERPRETATION: Delivery of PrEP to people who are incarcerated is feasible with adequate resourcing and support to the criminal justice health system, and can result in high uptake among eligible individuals. Further assessment is needed of PrEP persistence and adherence, and the perceptions of people who are incarcerated regarding their HIV risk and preferences for combination HIV prevention services. FUNDING: US President's Emergency Plan for AIDS Relief through the US Centers for Disease Control and Prevention.

    Peer community health workers improve HIV testing and ART linkage among key populations in Zambia: retrospective observational results from the Z-CHECK project, 2019-2020.

    INTRODUCTION: Zambia has made tremendous progress towards HIV epidemic control; however, gaps remain among key populations (KPs), such as female sex workers (FSWs), men who have sex with men (MSM), people who inject drugs (PWID) and people in prisons and enclosed settings due to cultural, social and legal barriers. The University of Maryland, Baltimore Zambia Community HIV Epidemic Control for Key Populations (Z-CHECK) project aimed to improve HIV case-finding, linkage and treatment adherence at the community level for KPs in Zambia. We describe Z-CHECK strategies and examine HIV positivity yield and antiretroviral therapy (ART) linkage among KPs to inform ongoing programme improvement. METHODS: Z-CHECK recruited, trained and deployed peer community health workers (CHWs) for KP groups, with ongoing mentorship in community engagement. CHWs offered HIV testing in safe spaces and escorted newly HIV-diagnosed clients for same-day ART initiation. Z-CHECK also reached out to KP community leaders and gatekeepers for KP mobilization and trained healthcare workers (HCWs) on KP services and sensitivity. We conducted a retrospective observational review of routinely collected aggregate data for KPs aged ≥15 years at high risk for HIV transmission across five districts in Zambia from January 2019 to December 2020. RESULTS: Z-CHECK provided HIV testing for 9211 KPs, of whom 2227 were HIV positive (positivity yield, 24%). Among these, 1901 (85%) were linked to ART; linkage for MSM, FSW, PWID and people in prisons and enclosed settings was 95%, 89%, 86% and 65%, respectively. Programme strategies that contributed to high positivity yield and linkage included the use of peer KP CHWs, social network testing strategies and opportunities for same-day ART initiation. Challenges to programme implementation included stigma and discrimination among HCWs, as well as KP CHW attrition, which may be explained by high mobility. CONCLUSIONS: Peer CHWs were highly effective at reaching KP communities, identifying persons living with HIV and linking them to care. Engaging KP community gatekeepers resulted in high diffusion of health messages and increased access to health resources. The mobility of CHWs and HCWs is a challenge for programme implementation. Innovative interventions are needed to support PWID and people in prisons and enclosed settings.
