Item Comparison of short messaging service self-reported adherence with other adherence measures in a demonstration project of HIV preexposure prophylaxis in Kenya and Uganda(AIDS (London, England), 2018) Musinguzi, Nicholas; Muwonge, Timothy; Ngure, Kenneth; Katabira, Elly; Mugo, Nelly; O’Rourke Burns, Bridget Frances; Baeten, Jared M.; Heffron, Renee; Haberer, Jessica E.Short messaging service (SMS) can collect adherence data on a frequent basis and is relatively anonymous, and therefore could potentially reduce recall and social desirability biases prevalent in other self-reported measures. Methods: We compared SMS self-reported adherence with three self-reported adherence questions (rating of ability to adhere, frequency of doses taken, percentage of doses taken) and two objective adherence measures [electronic adherence monitoring (EAM) and plasma tenofovir levels] using data from HIV-uninfected members of serodiscordant couples enrolled in a preexposure prophylaxis demonstration project in Kenya and Uganda. Results: Of 373 enrolled participants, 256 (69%) were male and median age at enrolment was 29 years (26, 35). Fifty-two percent were from Kenya and median education at enrolment was 10 years (7,12). Overall, median adherence was 90, 75, 85,94 and 79%, respectively, for self-report by SMS, rating, frequency, percentage and EAM adherence. Spearman’s correlation coefficient between SMS and interviewer- administered self-reported measures was 0.18 for rating and frequency, 0.22 for percentage and 0.14 for EAM (all P< 0.001). The estimated difference in average adherence between SMS and self-reported rating, frequency, percentage adherence and EAM was 8.1 (P < 0.001), 0.3 (P = 0.81), −5.2 (P < 0.001) and 9.5 (P < 0.001), respectively. Area under the receiver-operating curve assessing the ability of SMS self-report to discriminate between detectable and undetectable tenofovir was 0.51. Conclusion: Our study found low correlation between SMS self-report and other self-reported and objective adherence measures and did not discriminate between detectable and undetectable plasma tenofovir levels. Future use of SMS self-report should explore alternative means for reducing potential biases.Item Context matters: PrEP adherence is associated with sexual behavior among HIV serodiscordant couples in East Africa(Journal of acquired immune deficiency syndromes, 2017) Haberer, Jessica E.; Ngure, Kenneth; Muwonge, Timothy; Mugo, Nelly; Katabira, Elly; Heffron, Renee; Musinguzi, Nicholas; Bangsberg, David R.; Celum, Connie; Baeten, Jared M.Short message service (SMS) surveys are a promising tool for understanding whether pre-exposure prophylaxis (PrEP) adherence aligns with risk for HIV acquisition— a concept known as prevention-effective adherence. Methods—The Partners Demonstration Project was an open-label study of integrated PrEP and antiretroviral therapy (ART) delivery among high-risk HIV serodiscordant couples in East Africa. HIV-uninfected partners were offered PrEP until their HIV-infected partner had taken ART for ≥6 months. At 2 study sites, HIV-uninfected partners were offered enrollment into the Partners Mobile Adherence to PrEP (PMAP) sub-study based on ongoing PrEP use, personal cell phone ownership, and ability to use SMS. SMS surveys asked about PrEP adherence and sexual activity in the prior 24 hours; these surveys were sent daily for the 7 days prior and 7 days after routine study visits in the Partners Demonstration Project. Results—The PMAP sub-study enrolled 373 HIV-uninfected partners; 69% were male and mean age was 31 years. Participants completed 17,030 of 23,056 SMS surveys sent (74%) with a mean of 47 surveys per participant over 9.8 months of follow-up. While HIV-infected partner use of ART was <6 months, mean reported PrEP adherence was 92% on surveys concurrently reporting sex within the serodiscordant partnership and 84% on surveys reporting no sex (p<0.001). Discussion—SMS surveys provided daily assessment of concurrent PrEP adherence and sexual behavior. Higher PrEP adherence was temporally associated with increased risk for HIV acquisition.Item Health Care Worker Perspectives of HIV Pre-exposure Prophylaxis Service Delivery in Central Uganda(Frontiers in Public Health, 2022) Muwonge, Timothy R.; Nsubuga, Rogers; Ware, Norma C.; Wyatt, Monique A.; Pisarski, Emily; Kamusiime, Brenda; Kasiita, Vicent; Kakoola Nalukwago, Grace; Brown, Charles; Nakyanzi, Agnes; Bagaya, Monica; Bambia, Felix; Ssebuliba, Timothy; Katabira, Elly; Kyambadde, Peter; Baeten, Jared M.; Heffron, Renee; Celum, Connie; Mujugira, Andrew; Haberer, Jessica E.Scale-up of HIV pre-exposure prophylaxis (PrEP) services in Uganda is ongoing. However, health care workers (HCWs) may not be aware of PrEP nor what offering this service entails. We explored the impact of standardized HCW training on the knowledge and perspectives of PrEP service delivery in Uganda. Methods: We recruited HCWs from facilities that offered HIV-related services in Central Uganda. Using the Uganda Ministry of Health curriculum, we trained HCWs on PrEP services. We collected data about PrEP knowledge, preparedness, and willingness to deliver PrEP to multiple key populations before the training, immediately after the training, and >6 months later (exit). We additionally conducted 15 qualitative interviews after the exit survey. Quantitative data were analyzed by Fisher exact test, while qualitative interview data were analyzed inductively. Results: We recruited 80 HCWs from 35 facilities in urban (N = 24, 30%), peri-urban (N = 30, 37%), and rural (N = 26, 33%) areas. Most HCWs were nurse counselors (N = 52, 65%) or medical/clinical officers (N = 15, 18%). Surveys indicated that awareness of PrEP increased after the training and remained high. Knowledge of PrEP (i.e., as an effective, short-term antiretroviral medication to use before HIV exposure for people at high risk) generally increased with training, but significant gaps remained, and knowledge decreased with time. Most HCWs recommended PrEP for female sex workers and HIV serodifferent couples, as well as other key populations. We observed increases in the number of HCW who felt their facility was prepared to cater for HIV prevention and provide PrEP, but this view was not universal. HCWs believed in PrEP effectiveness and embraced it as an additional HIV prevention method. Concerns included patient adherence and behavioral risk compensation. HCWs noted challenges in PrEP delivery in terms of inadequate clinic preparedness, infrastructure, staff capacity, and poor attitudes toward key populations by untrained health workers. They felt further training was needed to ensure a smooth scale-up of services without stigmatization. Standardized training improved knowledge, willingness, and preparedness to offer PrEP services among most HCWs in Central Uganda. Ongoing training will be needed to optimize PrEP delivery services and expand delivery to levels needed for population-level impact.Item How PrEP delivery was integrated into public ART clinics in central Uganda: A qualitative analysis of implementation processes(Public Library of Science, 2024-03-07) Wyatt, Monique A; Pisarski, Emily E; Nalumansi, Alisaati; Kasiita, Vicent; Kamusiime, Brenda; Nalukwago, Grace K; Thomas, Dorothy; Muwonge, Timothy R; Mujugira, Andrew; Heffron, Renee; Ware, Norma CTailored delivery strategies are important for optimizing the benefit and overall reach of PrEP in sub-Saharan Africa. An integrated approach of delivering time-limited PrEP in combination with ART to serodifferent couples encourages PrEP use in the HIV-negative partner as a bridge to sustained ART use. Although PrEP has been delivered in ART clinics for many years, the processes involved in integrating PrEP into ART services are not well understood. The Partners PrEP Program was a stepped-wedge cluster randomized trial of integrated PrEP and ART delivery for HIV serodifferent couples in 12 public health facilities in central Uganda (Clinicaltrials.gov NCT03586128). Using qualitative data, we identified and characterized key implementation processes that explain how PrEP delivery was integrated into existing ART services in the Partners PrEP Program. In-depth interviews were conducted with a purposefully-selected sub-sample of 83 members of 42 participating serodifferent couples, and with 36 health care providers implementing integrated delivery. High quality training, technical supervision, and teamwork were identified as key processes supporting providers to implement PrEP delivery. Interest in the PrEP program was promoted through the numerous ways health care providers made integrated ART and PrEP meaningful for serodifferent couples, including tailored counseling messages, efforts to build confidence in integrated delivery, and strategies to create demand for PrEP. Couples in the qualitative sample responded positively to providers’ efforts to promote the integrated strategy. HIV-negative partners initiated PrEP to preserve their relationships, which inspired their partners living with HIV to recommit to ART adherence. Lack of disclosure among couples and poor retention on PrEP were identified as barriers to implementation of the PrEP program. A greater emphasis on understanding the meaning of PrEP for users and its contribution to implementation promises to strengthen future research on PrEP scale up in sub-Saharan Africa.Item Implementation of gender-based violence screening guidelines in public HIV treatment programs: A mixed methods evaluation in Uganda(Public Library of Science, 2024-05) Thomas, Dorothy; Nalumansi, Alisaati; Reichman, Mira; Metitiri, Mine; Nambi, Florence; Kibuuka, Joseph; Nakabugo, Lylianne; Kamusiime, Brenda; Kasiita, Vicent; Nalukwago, Grace K.; Muwonge, Timothy R; Simoni, Jane; Montgomery, Elizabeth T.; Mujugira, Andrew; Heffron, ReneeBackground HIV and gender-based violence (GBV) intersect to threaten population health. The Uganda Ministry of Health recommends routine GBV screening alongside HIV care but evidence detailing its implementation in HIV care settings is limited. We evaluated screening practices in public HIV clinics to generate evidence supporting GBV screening optimization. Methods To evaluate GBV screening implementation in antiretroviral therapy (ART) clinics, we extracted client data from GBV registers at 12 public ART clinics in Uganda (January 2019-December 2021). We concurrently evaluated perceptions of GBV screening/referral practices by conducting in-depth qualitative interviews with providers (N = 30) and referral partners (N = 10). We contextualized quantitative findings with interview data which were analyzed using a thematic analysis approach. Results During the evaluation period, >90% of providers in participating health facilities implemented GBV screening. Among 107,767 clients served in public ART clinics, providers identified 9,290 (8.6%) clients who experienced past-year physical, sexual and/or emotional GBV of whom 86% received counseling and 19% were referred to support services—most commonly to legal services. Key factors influencing GBV screening implementation included awareness of screening guidelines; client volume; and client’s level of engagement in HIV care. Providers and referral partners identified important benefits to clients (e.g., pursuit of justice and removal from violent environments) when referrals were successful. Key factors influencing referrals included financial constraints that limited referral partners’ ability to provide services at no cost to clients and socio-cultural norms that inhibited client willingness to pursue support services. Conclusions GBV screening implementation in ART clinics supports identification and referral of clients exposed to violence. The effectiveness of GBV screening may be limited by socio-cultural factors that inhibit client capacity to pursue referrals and fragmented and resource-constrained referral networks. Providers and referral partners identified allocating funds to support referrals and collaborative networking meetings as important opportunities for strengthening GBV referrals.Item Intimate partner violence and self-reported pre-exposure prophylaxis (PrEP) interruptions among HIV-negative partners in HIV serodiscordant couples in Kenya and Uganda(Journal of acquired immune deficiency syndromes, 2018) Cabral, Alejandra; Baeten, Jared; Ngure, Kenneth; Velloza, Jennifer; Odoyo, Josephine; Haberer, Jessica; Celum, Connie; Muwonge, Timothy; Asiimwe, Stephen; Heffron, ReneeOral pre-exposure prophylaxis (PrEP) is effective for HIV prevention and PrEP delivery studies are investigating ways to deliver PrEP with high adherence. However, in many settings with high HIV burden, intimate partner violence (IPV) is reported often and could be a barrier to effective PrEP use. We examined the association between IPV and interruptions in PrEP use. Methods—We analyzed data from 1,013 serodiscordant heterosexual couples enrolled in a large PrEP demonstration project in Kenya and Uganda, the Partners Demonstration Project. At quarterly study visits, HIV-negative participants receiving PrEP were asked about interruptions in their PrEP use and experiences with IPV. The association between IPV and PrEP interruptions was analyzed using multivariable generalized estimating equations. Results—At baseline and follow-up there were 53 visits with reports of abuse by 49 HIV-negative partners, including physical, economic, and verbal IPV. Interruptions in PrEP use were reported at 328 visits (7.1% of all visits) by 249 people. The median length of PrEP interruption was 28 days (interquartile range [IQR]: 7–45). The frequency of PrEP interruptions among those reporting IPV was 23.8% and those without IPV was 6.9%. PrEP interruption was significantly associated with IPV after adjustment for age and frequency of sexual intercourse (adjusted OR=2.6, 95% CI 1.2–6.0). Conclusion—IPV was more likely to be reported at visits when PrEP interruptions were also reported, which may have implications for sustained adherence to PrEP. Within PrEP delivery programs, there may be opportunities to assess individual safety and well-being in order to bolster adherence.Item A pragmatic approach to identifying implementation barriers and facilitators for a novel pre-exposure prophylaxis (PrEP) delivery model at public facilities in urban Uganda(Implementation Science Communications, 2022) Thomas, Dorothy; Mujugira, Andrew; Ortblad, Katrina; Namanda, Sylvia; Kibuuka, Joseph; Nakitende, Mai; Nambi, Florence; Nakabugo, Lylianne; Scoville, Caitlin; Muwonge, Timothy; Heffron, ReneeScalable HIV pre-exposure prophylaxis (PrEP) delivery models for resource-limited settings are critical for improving PrEP coverage and interrupting HIV transmission. This research uses technical assistance (TA) reports to evaluate implementation barriers and facilitators for a novel delivery model integrating PrEP and antiretroviral therapy (ART) delivery for HIV sero-different couples in public health facilities in Kampala, Uganda. Methods: We used data from the Partners PrEP Program (PPP)—a stepped-wedge cluster randomized trial that is launching PrEP delivery through an integrated model of oral PrEP and antiretroviral therapy (ART) delivery for HIV sero-different couples at public health facilities in Kampala and Wakiso, Uganda (NCT03586128). Technical assistance teams, comprised of PPP program staff, conducted monthly TA visits to implementing facilities where they identified and addressed implementation challenges in collaboration with health facility staff. Findings were recorded in TA reports, a standardized form structured using the Consolidated Framework for Implementation Research (CFIR). We used a conceptual content analysis approach to evaluate TA reports completed from January to December 2019 and identify implementation barriers and facilitators. Results: Among 39 reports from the 8 implementing facilities (~ 5 per facility), we identified 11 CFIR constructs. Key implementation facilitators included sensitizing and educating facility staff about PrEP (knowledge and beliefs about the innovation); establishing formal and informal feedback and accountability mechanisms (reflecting and evaluating); and empowering facility staff to address implementation challenges (self-efficacy). Key implementation barriers were related to ineffective recruitment and referral of sero-different couples to and from nearby facilities (cosmopolitanism) as well as stockouts of laboratory resources and testing supplies (available resources). Conclusions: This analysis featured a robust implementation science framework to assess the relationship between early implementation determinants and outcomes of this innovative PrEP delivery model. Further, we have provided important descriptions of early implementation barriers and facilitators that will inform scale-up efforts for PrEP delivery within and beyond Uganda. Future work will refine the analysis of pragmatic program data, qualitatively investigate the identified key themes, and explore strategies for addressing implementation barriers.Item PrEP Discontinuation and Prevention-Effective Adherence: Experiences of PrEP Users in Ugandan HIV Serodiscordant Couples(Journal of acquired immune deficiency syndromes, 2019) Gilbert, Hannah N.; Wyatt, Monique A.; Pisarski, Emily E.; Muwonge, Timothy R.; Heffron, Renee; Katabira, Elly T.; Celum, Connie L.; Baeten, Jared M.; Haberer, Jessica E.; Ware, Norma C.Optimal adherence to oral pre-exposure prophylaxis (PrEP) for HIV prevention involves aligning consistent PrEP use with periods of risk to achieve prevention-effective adherence. Prevention-effective adherence is predicated on individuals discontinuing PrEP during periods without expected risk. For stable, serodiscordant couples, ART adherence by the HIV-positive partner markedly decreases HIV transmission risk, potentially obviating the need for continued PrEP use; yet little is known about actual lived experiences of discontinuing PrEP. Methods: In-depth qualitative interviews were carried out with HIV-uninfected PrEP users in serodiscordant couples taking part in the Partners Demonstration Project at IDI-Kasangati, Kampala, Uganda. Open-ended interviews elicited information on the partnered relationship; understandings of PrEP; prevention strategies; and experiences of PrEP discontinuation. An inductive, thematic, content-analytic approach was used to analyze study data. Results: Uninfected partners experienced PrEP as a valued resource for preventing HIV acquisition. Despite ongoing ART use by HIV-positive partners for a period of time consistent with viral suppression, discontinuation of PrEP was experienced as a loss of protection and a corresponding increase in risk of HIV acquisition. Uninfected partners responded with strategies aimed at offsetting this subjective sense of increased risk, specifically: (1) changing sexual practices; (2) prioritizing fidelity in the relationship; (3) increasing reliance on condoms; and (4) seeking evidence of partners’ ART adherence. Conclusions: These experiences highlight the challenges PrEP users in serodiscordant couples face in discontinuing PrEP for prevention-effective adherence. Flexible interventions that support individuals during this transition may increase comfort with discontinuing PrEP when alternative prevention strategies provide protection, such as a partner’s consistent adherence to ART.Item PrEP uptake and HIV viral suppression when PrEP is integrated into Ugandan ART clinics for HIV-negative members of HIV-serodifferent couples: A stepped wedge cluster randomized trial(EClinicalMedicine, 2022) Heffron, Renee; Muwonge, Timothy R.; Thomas, Katherine K.; Nambi, Florence; Nakabugo, Lylianne; Kibuuka, Joseph; Thomas, Dorothy; Feutz, Erika; Meisner, Allison; Ware, Norma C.; Wyatt, Monique A.; Simoni, Jane M.; Katz, Ingrid T.; Kadama, Herbert; Baeten, Jared M.; Mujugira, AndrewGlobal scale-up of HIV pre-exposure prophylaxis (PrEP) includes services to HIV-negative people in partnerships with people living with HIV (serodifferent couples). Data are needed on HIV outcomes, including uptake and adherence to PrEP and antiretroviral treatment (ART), to describe the impact of integrating PrEP into an existing HIV program. Methods Using a stepped-wedge cluster randomized trial design, we launched PrEP delivery for HIV-negative members of serodifferent couples in Uganda by integrating PrEP into existing ART programs for people living with HIV. The program provided PrEP training for ART providers, ongoing technical assistance, and a provisional supply chain mechanism for PrEP medication. Primary data on PrEP initiation, PrEP refills, ART initiation, and HIV viremia at 6 months (measured at 42-270 days) were collected through data abstraction of medical records from HIV-serodifferent couples sequentially enrolling at the ART clinics. Modified Poisson regression models, controlling for time and cluster, compared viral suppression (<1000 copies/ml) before and after launch of the PrEP program. This trial was registered at ClinicalTrials.gov, NCT03586128. Findings From June 1, 2018-December 15, 2020, 1,381 HIV-serodifferent couples were enrolled across 12 ART clinics in Kampala and Wakiso, Uganda, including 730 enrolled before and 651 after the launch of PrEP delivery. During the baseline period, 99.4% of partners living with HIV initiated ART and 85.0% were virally suppressed at 6 months. Among HIV-negative partners enrolled after PrEP launched, 81.0% (527/651) initiated PrEP within 90 days of enrolling; among these 527, 11.2% sought a refill 6 months later. In our powered intent-to-treat analysis, 82.1% and 76.7% of partners living with HIV were virally suppressed, respectively, which was not a statistically significant difference (RR=0.94, 95% CI: 0.82-1.07) and was stable across sensitivity analyses. Interpretation Integration of PrEP into ART clinics reached a high proportion of people in HIV-serodifferent relationships and did not improve the already high frequency of HIV viral suppression among partners living with HIV.Item Sexual behavior and perceived HIV risk among HIV-negative members of serodiscordant couples in East Africa(AIDS and Behavior, 2020) Wanga, Valentine; Baeten, Jared M.; Bukusi, Elizabeth A.; Mugo, Nelly R.; Asiimwe, Stephen; Ngure, Kenneth; Mujugira, Andrew; Muwonge, Timothy; Odoyo, Josephine B.; Haberer, Jessica E.; Celum, Connie; Heffron, ReneeHIV risk perception may influence the use of HIV prevention interventions. Using data from HIV-negative adults enrolled in a study of pre-exposure prophylaxis (PrEP) and antiretroviral therapy for HIV-serodiscordant couples in Kenya and Uganda, we examined associations between: 1) condom use and risk perception and 2) risk perception and PrEP adherence. Two-thirds of HIV-negative partners reported condomless sex with their HIV-positive partner or another partner in the month prior to study enrollment. Compared to those who reported no condomless sex, participants who reported condomless sex during the month prior to study visit had 5-fold higher odds of reporting “high risk” vs “no risk” perception (36.3 versus 10.9%: aOR=4.9, 95% CI: 3.4–6.9). Reporting condomless sex in the most recent sex act was associated with increased odds of perceiving some HIV risk (aOR for high risk=7.3, 95% CI 4.9–10.8; aOR for moderate risk=4.8, 95% CI 3.5–6.7; aOR for low risk=3.5, 95% CI 2.7–4.6). We found no significant association between risk perception and PrEP adherence. Sexual behavior aligned with perceived HIV risk, which can facilitate an HIV-negative individual’s decisions about PrEP use.Item Short message service (SMS) surveys assessing pre-exposure prophylaxis (PrEP) adherence and sexual behavior are highly acceptable among HIV-uninfected members of serodiscordant couples in East Africa: A mixed methods study(AIDS and Behavior, 2019) Muwonge, Timothy R.; Ngure, Kenneth; Katabira, Elly; Mugo, Nelly; Kimemia, Grace; O'Rourke Burns, Bridget Frances; Musinguzi, Nicholas; Bambia, Felix; Baeten, Jared M.; Heffron, Renee; Haberer, Jessica E.Short message service (SMS) surveys are a promising data collection method and were used to measure sexual behavior and adherence to HIV pre-exposure prophylaxis (PrEP) among HIV-uninfected partners of serodiscordant couples enrolled in a sub-study of the Partners Demonstration Project (an open-label study of integrated antiretroviral therapy and PrEP for HIV prevention in Kenya and Uganda). Questionnaires were completed by 142 participants after study exit. Median age was 29 years; 69% were male. Ninety-five percent (95%) felt SMS surveys were “easy” or “very easy”, 74% reported no challenges, and 72% preferred SMS surveys over in-person study visits. Qualitative interviews involving 32 participants confirmed the ease of responding to SMS surveys. Participants also indicated that surveys acted as reminders for adherence to PrEP and condom use and were experienced as support from the study. SMS surveys were generally found to be acceptable in this population and provided real-time context of PrEP use.Item Understanding early implementation of pre-exposure prophylaxis for HIV prevention in public health facilities in Uganda using the Consolidated Framework for Implementation Research(Clinics, 2019) Ortblad, Katrina; Brown, Charles; Muwonge, Timothy R.; Scoville, Caitlin; Izizinga, Diego; Namanda, Sylvia; Nambi, Florence; Nakabugo, Lylianne; Mujugira, Andrew; Heffron, ReneeIn sub-Saharan Africa, a number of countries are starting to deliver oral preexposure prophylaxis (PrEP) for HIV prevention in public health facilities. • We are conducting a stepped-wedge cluster-randomized trial in 12 health facilities in Kampala & Wakiso, Uganda to launch delivery of a PrEP program within HIV clinics targeting HIV-negative members of HIV serodiscordant couples and determine the impact of the PrEP program on HIV viral suppression in partners living with HIV (ClinicalTrials.gov)Item Users May Lack Confidence in ART for HIV Prevention: A Qualitative Analysis(Conference on retroviruses and opportunistic infections (CROI), 2017) Wyatt, Monique A.; Pisarski, Emily E.; Baeten, Jared M.; Heffron, Renee; Nakku-Joloba, Edith; Muwonge, Timothy R.; Katabira, Elly T.; Celum, Connie L.; Ware, Norma C.Antiretroviral-based approaches to HIV prevention have been shown to reduce new infections in clinical trials and demonstration settings. To optimize uptake and anticipate barriers to effective rollout, we must understand users’ perspectives on antiretroviral treatment (ART) for prevention of HIV transmission. We explored serodiscordant couples’ understandings of and feelings about treatment as prevention using qualitative data from the Partners Demonstration Project. The Partners Demonstration Project employed an integrated delivery strategy of daily oral pre-exposure prophylaxis (PrEP) and ART for serodiscordant couples in Kenya and Uganda. PrEP use was time-limited and discontinued after HIVinfected partners had been on ART for 6 months. Multiple in-depth qualitative interviews were conducted with a subset of 48 couples from the Kampala, Uganda Partners Demonstration Project site (N interviews=195). Interview topics included: (a) perceived purpose and meanings of PrEP and ART; (b) adherence; (c) experiences of PrEP discontinuation; and (d) understandings of antiretroviral treatment as prevention. Interviews were audio-recorded, transcribed into English and coded using Atlas.ti software by two trained analysts. Coded data were inductively analyzed to identify themes representing couples’ understandings of and feelings about using ART for prevention of HIV transmission. Categories were developed to represent the themes.
