"My future is bright…I won't die with the cause of AIDS": ten-year patient ART outcomes and experiences in South Africa.

ABSTRACT:

Introduction

South Africa is moving into a new era of HIV treatment with "treat all" policies where people may be on treatment for most of their lives. We need to understand treatment outcomes and facilitators of long-term antiretroviral treatment (ART) adherence and retention-in-care in the South African context. In one of the first studies to investigate long-term treatment outcomes in South Africa, we aimed to describe ten-year patient outcomes at a large public-sector HIV clinic in Johannesburg and explore patient experiences of the treatment programme over this time in order to ascertain factors that may aid or hinder long-term adherence and retention.

Methods

We conducted a cohort analysis (n = 6644) and in-depth interviews (n = 24) among HIV-positive adults initiating first-line ART between April 2004 and March 2007. Using clinical records, we ascertained twelve-month and ten-year all-cause mortality and loss to follow-up (LTF). Cox proportional hazards regression was used to identify baseline predictors of attrition (mortality and LTF (>3 months late for the last scheduled visit)) at twelve months and ten years. Twenty-four patients were purposively selected and interviewed to explore treatment programme experiences over ten years on ART.

Results

Excluding transfers, 79.5% (95% confidence intervals (CI): 78.5 to 80.5) of the cohort were alive, in care at twelve months dropping to 35.1% (95% CI: 33.7 to 36.4) at ten years. Over 44% of deaths occurred within 12 months. Ten-year all-cause mortality increased, while LTF decreased slightly, with age. Year and age at ART initiation, sex, nationality, baseline CD4 count, anaemia, body mass index and initiating regimen were predictors of ten-year attrition. Among patients interviewed, the pretreatment clinic environment, feelings of gratitude and good fortune, support networks, and self-efficacy were facilitators of care; side effects, travel and worsening clinical conditions were barriers. Participants were generally optimistic about their futures and were committed to continued care.

Conclusions

This study demonstrates the complexities of long-term chronic HIV treatment with declining all-cause mortality and increasing LTF over ten years. Barriers to long-term retention still present a significant challenge. As more people become eligible for ART in South Africa under "treatment for all," new healthcare delivery challenges will arise; interventions are needed to ensure long-term programme successes continue.

Project description:The ANRS 12249 Treatment-as-Prevention (TasP) cluster-randomized trial in rural South Africa uses a "test and treat" approach. Home-based testing services and antiretroviral treatment initiation satellite clinics were implemented in every cluster as part of the trial. A social science research agenda was nested within TasP with the aim of understanding the social, economic and contextual factors that affect individuals, households, communities and health systems with respect to TasP. Considering the rural nature of the trial setting, we sought to understand community perceptions and experiences of the TasP Trial interventions as seen through the eyes of traditional health practitioners (THPs). A qualitative study design was adopted using four repeat focus group discussions conducted with nine THPs, combined with community walks and photo-voice techniques, over a period of 18 months. A descriptive, interpretive and explanatory approach to analysis was adopted. Findings indicate that THPs engaged with the home-based testing services and HIV clinics established for TasP. Specifically, home-based testing services were perceived as relatively successful in increasing access to HIV testing. A major gap observed by THPs was linkage to HIV clinics. Most of their clients, and some of the THPs themselves, found it difficult to use HIV clinics due to fear of labelling, stigma and discrimination, and the ensuing personal implications of unsolicited disclosure. On the one hand, a growing number of patients diagnosed with HIV have found sanctuary with THPs as alternatives to clinics. On the other hand, THPs in turn have been struggling to channel patients suspected of HIV into clinics through referrals. Therefore, acceptability of the TasP test and treat approach by THPs is a major boost to the intervention, but further success can be achieved through strengthened ties with communities to combat stigma and effectively link patients into HIV care, including partnerships with THPs themselves.
