Objectives To characterize antiretroviral therapy (ART) adherence across different programmes and examine the relationship between individual and programme characteristics and incomplete adherence among ART clients in sub-Saharan Africa. Design A cross-sectional study. Methods Systematically selected ART clients (≥18 years; on ART ≥6 months) attending 18 facilities in three countries (250 clients/facility) were interviewed. Client self-reports (3-day, 30-day, Case Index ≥48 consecutive hours of missed ART), healthcare provider estimates and the pharmacy medication possession ratio (MPR) were used to estimate ART adherence. Participants from two facilities per country underwent HIV RNA testing. Optimal adherence measures were selected on the basis of degree of association with concurrent HIV RNA dichotomized at less than or greater/equal to 1000 copies/ml. Multivariate regression analysis, adjusted for site-level clustering, assessed associations between incomplete adherence and individual and programme factors. Results A total of 4489 participants were included, of whom 1498 underwent HIV RNA testing. Nonadherence ranged from 3.2% missing at least 48 consecutive hours to 40.1% having an MPR of less than 90%. The percentage with HIV RNA at least 1000 copies/ml ranged from 7.2 to 17.2% across study sites (mean = 9.9%). Having at least 48 consecutive hours of missed ART was the adherence measure most strongly related to virologic failure. Factors significantly related to incomplete adherence included visiting a traditional healer, screening positive for alcohol abuse, experiencing more HIV symptoms, having an ART regimen without nevirapine and greater levels of internalized stigma. Conclusion Results support more in-depth investigations of the role of traditional healers, and the development of interventions to address alcohol abuse and internalized stigma among treatment-experienced adult ART patients.

OBJECTIVES We assessed retention and predictors of attrition (recorded death or loss to follow-up) in antiretroviral treatment (ART) clinics in Tanzania, Uganda and Zambia. METHODS We conducted a retrospective cohort study among adults (≥18 years) starting ART during 2003–2010. We purposefully selected six health facilities per country and randomly selected 250 patients from each facility. Patients who visited clinics at least once during the 90 days before data abstraction were defined as retained. Data on individual and programme level risk factors for attrition were obtained through chart review and clinic manager interviews. Kaplan–Meier curves for retention across sites were created. Predictors of attrition were assessed using a multivariable Cox-proportional hazards model, adjusted for site-level clustering. RESULTS From 17 facilities, 4147 patients were included. Retention ranged from 52.0% to 96.2% at 1 year to 25.8%–90.4% at 4 years. Multivariable analysis of ART initiation characteristics found the following independent risk factors for attrition: younger age [adjusted hazard ratio (aHR) and 95% confidence interval (95%CI) = 1.30 (1.14–1.47)], WHO stage 4 ([aHR (95% CI): 1.56 (1.29–1.88)], >10% bodyweight loss [aHR (95%CI) = 1.17 (1.00–1.38)], poor functional status [ambulatory aHR (95%CI) = 1.29 (1.09–1.54); bedridden aHR1.54 (1.15–2.07)], and increasing years of clinic operation prior to ART initiation in government facilities [aHR (95%CI) = 1.17 (1.10–1.23)]. Patients with higher CD4 cell count were less likely to experience attrition [aHR (95%CI) = 0.88 (0.78–1.00)] for every log (tenfold) increase. Sites offering community ART dispensing [aHR (95% CI) = 0.55 (0.30–1.01) for women; 0.40 (0.21–0.75) for men] had significantly less attrition. CONCLUSIONS Patient retention to an individual programme worsened over time especially among males, younger persons and those with poor clinical indicators. Community ART drug dispensing programmes could improve retention.

The AIDS Support Organization (TASO) is an indigenous non-governmental organization (NGO) of HIV-infected and affected people in Uganda. TASO provides counselling, social support, medical and nursing care for opportunistic infections at 7 centres affiliated to district hospitals in Uganda. Between 1993 and 1994, the services provided by TASO were evaluated through a participatory approach between staff and clients. TASO counselling services helped clients and their families to cope with HIV and AIDS, with 90.4% of clients revealing their serostatus, and 57.2% reporting consistent use of condoms in the past 3 months. TASO was also the main source of medical care for clients with opportunistic infections in the last 6 months (63.8%). As a result of counselling, over half of the clients (56.9%) made plans for the future and 51.3% wished to make wills. There was a high level of acceptance of people living with HIV/AIDS (PWAs) by families (79%) and the community (76%). Care was provided to PWAs at home mainly by women (86.2%). TASO has demonstrated that individuals and their families are able to live positively with HIV/AIDS. Through counselling, medical care and material support to clients and their families, TASO has effected change in people's attitudes, knowledge and lifestyles. In particular, TASO has demonstrated a strong capacity to overcome four problems that haunt AIDS care in most places: (1) revealing one's HIV-serostatus to relevant others; (2) accepting PWAs in family and community; (3) seeking early treatment; and (4) combining prevention and care. In general, TASO has shown that specialized services to meet AIDS care needs can be added to existing health services at district levels. As a result of the participatory evaluation, a well-accepted monitoring system was established.
