Participants were invited to take part in semi-structured phone or in-person interviews to explore HIV prevention and PrEP care experiences overall and within bridge clinic settings.

Providers and WSWUD described facilitators and barriers to PrEP across the steps of the care continuum: Awareness, uptake, adherence, and retention. Facilitators for WSWUD included non-stigmatizing communication with providers, rapid wraparound substance use treatment and HIV services, having a PrEP routine, and service structures to support PrEP adherence. Barriers included low HIV risk perceptions and competing drug use and survival priorities. Provider facilitators included clinical note templates prompting HIV risk assessments and training. Barriers included discomfort discussing sex work risks, competing clinical priorities, and a lack of PrEP adherence infrastructure.</p><p><strong>Conclusion: </strong>WSWUD and bridge clinic providers favored integrated HIV prevention and substance use services in harm reduction and bridge clinic settings.

PrEP research among PWUD is scarce, and the factors that impact implementation are largely unknown. Therefore, we conducted a scoping review of implementation determinants (i.e., barriers and facilitators), as well as the change methods (implementation strategies and adjunctive interventions) that have been evaluated to increase PrEP implementation and use among PWUD. We identified 32 peer-reviewed articles assessing determinants and five that evaluated change methods. Determinants were coded using the updated Consolidated Framework for Implementation Research (CFIR), which is an established framework to understand the multilevel barriers and facilitators associated with implementation. Findings indicate that most research was conducted among PrEP recipients (i.e., patients), focusing on awareness and willingness to use PrEP, with less focus on factors impacting clinicians and service delivery systems. Moreover, very few change methods have been evaluated to improve clinician adoption and adherence to CDC guidelines for PrEP provision and/or recipient uptake and adherence to PrEP. Future research is needed that focuses on factors impacting implementation from a clinician standpoint as well as innovative change methods to increase PrEP awareness, reach, adoption, and sustained adherence to guidelines.

In 2020, Uganda introduced the ‘medication for opioid use disorder (MOUD) treatment’ for People who inject drugs (PWID). We analysed the 12-month retention and associated factors among PWID enrolled on MOUD treatment in Kampala, Uganda. We conducted a retrospective analysis of 343 PWID with OUD who completed 14 days of methadone induction from September 2020 to July 2022. Retention was defined as the number of individuals still in the programme divided by the total number enrolled, computed at 3-, 6-, 9-, and 12 months using lifetable and Kaplan-Meier survival analyses. Cox proportional regression analyses were conducted to assess factors associated with retention in the programme in the first 12 months. Overall, 243 (71%) of 343 participants stabilized at a methadone dose of 60 mg or more. The majority of participants were males (n = 284, 82.8%), and the median (interquartile range, IQR) age was 31 (26–38) years. Most participants (n = 276, 80.5%) lived 5 km or more away from the MOUD clinic. Thirty (8.8%) were HIV-positive, 52 (15.7%) had a major mental illness and 96 (27.9%) had a history of taking alcohol three months before enrollment. The cumulative retention significantly declined from 83.4% (95%CI = 79.0–87.0) at 3months to 71.9% (95%CI = 67.2–76.6) at 6months, 64% 95%CI = 58.7–68.9) at 9months, and 55.2%; 95% CI (49.8–60.3% at 12months. The 12-month retention was significantly higher for participants on methadone doses of 60 mg or more (adj.HR = 2.1, 95%CI = 1.41–3.22), while participants resident within 5 km of the MOUD clinic were 4.9 times more likely to be retained at 12 months, compared to those residing 5 km or more, (adj. HR = 4.81, 95%CI = 1.54-15). Other factors, including predisposing, need, and enabling factors, were not associated with retention. Our study demonstrates acceptable 12-month retention rates for people who inject drugs, comparable to previous studies done in both developing and developed countries. Sustaining and improving retention may require enhanced scaling up of MOUD dose to an optimal level in the first 14 days and reducing the distance between participant locale and MOUD clinics.","PeriodicalId":54223,"journal":{"name":"Addiction Science & Clinical Practice","volume":"42 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140925989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
