ABSTRACT The treatment outcomes for large-scale public antiretroviral therapy (ART) programs in developing countries, although promising, are still preliminary. The scaling-up of ART in resource-limited settings is inevitably hampered by human resource shortages. Therefore, community support for ART patients may play an important role in achieving favorable treatment outcomes. This study aimed to extend the current literature by investigating how immunological and virological responses to ART, measured at three points in time (after six, 12, and 24 months of ART), are influenced by patient characteristics (age, sex), health literacy (educational level and knowledge about HIV/AIDS), baseline CD4 cell count, baseline viral load, and three forms of community support (treatment buddy, community health worker [CHW], and HIV/AIDS support group). Cross-lagged regression analysis was used to test these relationships in a sample of 268 patients enrolled in the public-sector ART program of the Free State Province of South Africa (2004-2007). After 24 months of ART, 76.4% of patients were classified as treatment successes (viral load < 400 copies/mL, CD4 > or = 200 cells/microL), compared with 64.1% at 12 months and 46.1% at six months. When we examined the predictors of ART success, baseline health and all three community support initiatives had a positive effect on ART outcomes after six months, whereas patient characteristics had little effect. Six months later, patients with the support of a treatment buddy, CHW, or support group had better ART outcomes, whereas the impact of baseline health had diminished. After two years of treatment, community support again emerged as the most important predictor of treatment success. This study confirms that the ART provided by South African public-sector health services is effective. These results provide evidence from the field that communities can be mobilized to sustain these favorable outcomes under conditions of limited human resources for healthcare.

    ABSTRACT: Given the severe shortage of human resources in the healthcare sector in many countries with high HIV prevalence, community-based peer adherence support is being increasingly cited as an integral part of a sustainable antiretroviral treatment (ART) strategy. However, the available scientific evidence on this topic reports discrepant findings on the effectiveness of peer adherence support programmes. These conflicting findings to some extent can be attributed to the lack of attention to the social contexts in which peer adherence support programmes are implemented. This study explores the potential moderating role of family dynamics by assessing the differential impact of peer adherence support in different types of families, based on the theoretical underpinnings of the family functioning framework. These relationships were explored with the aid of multivariate statistical analysis of cross-sectional, post-trial data for a sample of 340 patients interviewed as part of the Effectiveness of Aids Treatment and Support in the Free State (FEATS) study conducted in the public-sector ART programme of the Free State Province of South Africa. The analysis reveals no significant overall differences in CD4 cell count between the intervention group accessing additional peer adherence support and the control group receiving standard care. When controlling for the potential moderating role of family dynamics, however, the outcomes clearly reveal a significant interaction effect between the adherence intervention and the level of family functioning with regard to treatment outcomes. Multi-group analysis demonstrates that peer adherence support has a positive effect on immunological restoration in well-functioning families, while having a negative effect in dysfunctional families. The study outcomes stress the need for peer adherence interventions that are sensitive to the suboptimal contexts in which they are often implemented. Generic, broad-based interventions do not necessarily facilitate the treatment adherence of the most vulnerable patient groups, particularly those without supportive family contexts. Tailoring interventions aimed at creating a health-enabling environment to the needs of these at-risk patients should therefore be a priority for both research and policy.

    ABSTRACT: Since the introduction of antiretroviral treatment, HIV/AIDS can be framed as a chronic lifelong condition, requiring lifelong adherence to medication. Reinforcement of self-management through information, acquisition of problem solving skills, motivation, and peer support is expected to allow PLWHA to become involved as expert patients in the care management and to decrease the dependency on scarce skilled medical staff. We developed a conceptual framework to analyse how PLWHA can become expert patients and performed a literature review on involvement of PLWHA as expert patients in ART provision in Sub-Saharan Africa. This paper revealed two published examples: one on trained PLWHA in Kenya and another on self-formed peer groups in Mozambique. Both programs fit the concept of the expert patient and describe how community-embedded ART programs can be effective and improve the accessibility and affordability of ART. Using their day-to-day experience of living with HIV, expert patients are able to provide better fitting solutions to practical and psychosocial barriers to adherence. There is a need for careful design of models in which expert patients are involved in essential care functions, capacitated, and empowered to manage their condition and support fellow peers, as an untapped resource to control HIV/AIDS.

    ABSTRACT: Given relatively high levels of adherence to HIV treatment in Africa, we explore factors facilitating children's adherence, despite poverty, social disruption and limited health infrastructure. Using interviews with 25 nurses and 40 guardians in Zimbabwe, we develop our conceptualisation of an 'adherence competent community', showing how members of five networks (children, guardians, community members, health workers and NGOs) have taken advantage of the gradual public normalisation of HIV/AIDS and improved drug and service availability to construct new norms of solidarity with HIV and AIDS sufferers, recognition of HIV-infected children's social worth, an ethic of care/assistance and a supporting atmosphere of enablement/empowerment.
