BACKGROUNDTo assess the impact of combination HIV prevention (CHP) on HIV incidence, we analyzed the association between HIV incidence and scale-up of antiretroviral therapy (ART) and medical male circumcision in Rakai, Uganda. Changes in population-level viral load suppression and sexual behaviors were also examined.METHODSBetween 1999 and 2016, data were collected through 12 surveys from 30 communities in the Rakai Community Cohort Study, an open population-based cohort of persons aged 15-49 years. We assessed HIV incidence trends based on observed seroconversion data, self-reported ART and male circumcision coverage, viral load suppression, and sexual behaviors.RESULTSIn total, 33,937 study participants contributed 103,011 person-visits (HIV prevalence ~13%). Follow-up of 17,870 HIV-negative persons contributed 94,427 person-years with 931 seroconversions. ART was introduced in 2004; by 2016 coverage was 69% (72% in women vs. 61% in men, p<0.001). HIV viral load suppression among all HIV-positive persons increased from 42% in 2009 to 75% by 2016 (p<0.001). Male circumcision coverage increased from 15% in 1999 to 59% by 2016 (p<0.001). Persons 15-19 years reporting n 71 ever having sex increased from 30% to 55% (p<0.0001). HIV incidence declined by 42% in 2016 relative to the pre-CHP period prior to 2010 (1.17/100 py to 0.66/100 py; adjIRR:0.58: 95%CI: 0.45-0.76); declines were greater in men (adjIRR=0.46; 95%CI: 0.29-0.73) than women (adjIRR=0.68, 95%CI: 0.50-0.94).CONCLUSIONSIn this longitudinal study, HIV incidence significantly declined with CHP scale-up, providing empiric evidence that HIV control interventions can have substantial population-level impact. However, additional efforts are needed to overcome gender disparities and achieve HIV elimination.

Task shifting to community health workers (CHW) has received recognition. We examined the performance of community antiretroviral therapy and tuberculosis treatment supporters (CATTS) in scaling up antiretroviral therapy (ART) in Reach Out, a community-based ART program in Uganda. Retrospective data on home visits made by CATTS were analyzed to examine the CATTS ability to perform home visits to patients based on the model's standard procedures. Qualitative interviews conducted with 347 randomly selected patients and 47 CATTS explored their satisfaction with the model. The CATTS ability to follow-up with patients worsened from patients requiring daily, weekly, monthly, to three-monthly home visits. Only 26% and 15% of them correctly home visited patients with drug side effects and a missed clinic appointment, respectively. Additionally, 83% visited stable pre-ART and ART patients (96%) more frequently than required. Six hundred eighty of the 3650 (18%) patients were lost to follow-up (LTFU) during the study period. The mean number of patients LTFU per CATTS was 40.5. Male (p = 0.005), worked for longer durations (p = 0.02), and had lower education (p = 0.005). An increased number of patients (p = 0.01) were associated with increased LTFU. Ninety-two percent of the CATTS felt the model could be improved by reducing the workload. CATTS who were HIV positive, female, not residing in the same village as their patients, more educated, married, on ART, and spent less time with the patients were rated better by their patients. The Reach-Out CHW model is labor-intensive. Triaged home visits could improve performance and allow CATTS time to focus on patients requiring more intensive follow-up.

Background There is growing concern about the human resources needed to care for increasing numbers of patients receiving antiretroviral therapy in resource-limited settings. We evaluated an alternative model, community-based, comprehensive antiretroviral program staffed primarily by peer health workers and nurses. Methods We conducted a retrospective cohort study of patients receiving antiretroviral therapy during the first 10 months of program enrollment beginning in late 2003. Virologic, immunologic, clinical, and adherence data were collected. Results Of 360 patients started on treatment, 258 (72%) were active and on therapy approximately two years later. Viral load testing demonstrated that 86% of active patients (211 of 246 tested) had a viral load <400 copies/mL. The median CD4 increase for active patients was 197 cells/mm3 (IQR, 108–346). Patients with either a history of antiretroviral use or lack of CD4 response were more likely to experience virologic failure. Survival was 84% at one year and 82% at two years. WHO stage 4 was predictive of both not sustaining therapy and increased mortality. Conclusions A community-based antiretroviral treatment program in a resource-limited setting can provide excellent AIDS care over at least a two year period. A comprehensive program based upon peer health workers and nurses provides an effective alternative model for AIDS care.

Introduction Pre‐exposure prophylaxis (PrEP) programmes have been initiated in sub‐Saharan Africa to prevent HIV acquisition in key populations at increased risk. However, data on PrEP uptake and retention in high‐risk African communities are limited. We evaluated PrEP uptake and retention in HIV hyperendemic fishing villages and trading centres in south‐central Uganda between April 2018 and March 2019. Methods PrEP eligibility was assessed using a national risk screening tool. Programme data were used to evaluate uptake and retention over 12 months. Multivariable modified Poisson regression estimated adjusted prevalence ratios (aPR) and 95% Confidence intervals (CIs) of uptake associated with covariates. We used Kaplan–Meier analysis to estimate retention and multivariable Cox regression to estimate adjusted relative hazards (aRH) and 95% CIs of discontinuation associated with covariates. Results and discussion Of the 2985 HIV‐negative individuals screened; 2750 (92.1 %) were eligible; of whom 2,536 (92.2%) accepted PrEP. Male (aPR = 0.91, 95% CI = 0.85 to 0.97) and female (aPR = 0.85, 95% CI = 0.77 to 0.94) fisher folk were less likely to accept compared to HIV‐discordant couples. Median retention was 45.4 days for both men and women, whereas retention was higher among women (log rank, p < 0.001) overall. PrEP discontinuation was higher among female sex workers (aRH = 1.42, 95% CI = 1.09 to 1.83) and female fisher folk (aRH = 1.99, 95% CI = 1.46 to 2.72), compared to women in discordant couples. Male fisher folk (aRH = 1.37, 95% CI = 1.07 to 1.76) and male truck drivers (aRH = 1.49, 95% CI = 1.14 to 1.94) were more likely to discontinue compared to men in discordant couples. Women 30 to 34 years tended to have lower discontinuation rates compared to adolescents 15 to 19 years (RH = 0.78 [95% CI = 0.63 to 0.96]). Conclusions PrEP uptake was high, but retention was very low especially among those at the highest risk of HIV: fisher folk, sex workers and truck drivers and adolescent girls. Research on reasons for PrEP discontinuation could help optimize retention.
