RESUMO

The 2022 Russian invasion of Ukraine has caused serious challenges for healthcare workers (HCWs) and HIV-related healthcare services. This study assessed the effects of the invasion on HCWs wellbeing and on continuity of HIV services, using in-depth interviews with HCWs from facilities offering HIV antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) services in the Donetsk region of Eastern Ukraine. A directed content analysis, with both inductive and deductive approaches, was conducted. Ten HCWs (6 [60%] doctors, 4 [40%] nurses; 9 [90%] female) were interviewed. Six respondents were displaced from their homes and worksites, and all described stress and threats to emotional wellbeing. HCWs used online consultations, encrypted mobile communication, and multi-month dispensing to support continuity of ART and PrEP services. They noted immediate needs for psychological and financial support, and access to laptop computers and mobile communications to ensure continuity of HIV services. Priorities for restoration of services include repair of health facilities, restoration of laboratory services and supply chains, and return of personnel and patients. HCWs made innovative, rapid adaptations to HIV services to keep ART and PrEP services running, demonstrating the resolve of Ukrainian HCWs to maintain continuity of HIV services despite the disruptions of war.

RESUMO

BACKGROUND: Ukraine has implemented ambitious HIV-prevention programs since 1999 and began offering preexposure prophylaxis (PrEP) in 2017. Little is known about PrEP uptake and persistence in this setting. SETTING: We analyzed data from 40 facilities providing PrEP in 11 oblasts (regions) of Ukraine between October 2020 and February 2022. METHODS: We estimated the time between PrEP visits and conducted Kaplan-Meier analyses to estimate retention on PrEP stratified by sex, age, and key populations (KPs): men who have sex with men (MSM), people who inject drugs (PWID), sex workers (SW), discordant couples, and others vulnerable to HIV acquisition (DC/other). We used Cox regression to estimate the risk of PrEP discontinuation by KP group and sex, adjusting for age. RESULTS: Overall, 2033 clients initiated PrEP across regions; the majority (51%) were DC/other, 22% were MSM, 22% were PWID, and 5% were SW. The overall 3-month persistence was 52.3% (95% confidence interval [CI]: 49.9% to 54.8%) and was lowest among MSM (46.7%; 95% CI: 41.9% to 52.2%) and SW (25.9%; 95% CI: 18.2% to 36.9%) (P < 0.05 for differences by KP group). After adjusting for age, PrEP discontinuation was not statistically significantly different across groups, although female PWID tended to have the lowest discontinuation risk (adjusted hazard ratio [aHR] 0.59; 95% CI: 0.31 to 1.11) while male SW tended to have the highest risk (aHR 1.87, 95% CI: 0.57 to 6.11) compared with females in the DC/other group. CONCLUSION: Three-month PrEP persistence was low across KP groups, especially in SW. Further research examining the barriers and enablers of persistence by KPs is needed.

RESUMO

BACKGROUND: Community-based oral pre-exposure prophylaxis (PrEP) provision has the potential to expand PrEP coverage. HIV self-testing can facilitate PrEP community-based delivery but might have lower sensitivity than facility-based HIV testing, potentially leading to inappropriate PrEP use among people with HIV and subsequent development of drug resistance. We aimed to evaluate the impact of HIV self-testing use for PrEP scale-up. METHODS: We parameterised an agent-based network model, EMOD-HIV, to simulate generic tenofovir disoproxil fumarate and emtricitabine PrEP scale-up in western Kenya using four testing scenarios: provider-administered nucleic acid testing, provider-administered rapid diagnostic tests detecting antibodies, blood-based HIV self-testing, or oral fluid HIV self-testing. Scenarios were compared with a no PrEP counterfactual. Individuals aged 18-49 years with one or more heterosexual partners who screened HIV-negative were eligible for PrEP. We assessed the cost and health impact of rapid PrEP scale-up with high coverage over 20 years, and the budget impact over 5 years, using various HIV testing modalities. FINDINGS: PrEP coverage of 29% was projected to avert approximately 54% of HIV infections and 17% of HIV-related deaths among adults aged 18-49 years over 20 years; health impacts were similar across HIV testing modalities used to deliver PrEP. The percentage of HIV infections with PrEP-associated nucleoside reverse transcriptase inhibitor (NRTI) drug resistance was 0·6% (95% uncertainty intervals 0·4-0·9) in the blood HIV self-testing scenario and 0·8% (0·6-1·0) in the oral HIV self-testing scenario, compared with 0·3% (0·2-0·3) in the antibody rapid diagnostic testing scenario and 0·2% (0·1-0·2) in the nucleic acid testing scenario. Accounting for background NRTI resistance, we found similarly low proportions of drug resistance across scenarios. The budget impact of implementing PrEP using HIV self-testing and provider-administered rapid diagnostic tests were similar, while nucleic acid testing was approximately 50% more costly. INTERPRETATION: Scaling up PrEP using HIV self-testing has similar health impacts, costs, and low risk of drug resistance as provider-administered rapid diagnostic tests. Policy makers should consider leveraging HIV self-testing to expand PrEP access among those at HIV risk. FUNDING: The Bill and Melinda Gates Foundation.
