Differentiated antiretroviral therapy delivery in rural Zimbabwe: availability, needs and challenges

Introduction: The traditional “one-size-fits-all” model of HIV care whereby people living with HIV (PLWH) have regular individual clinical visits does not reflect the various preferences and needs of PLWH and stretches the capacity of health facilities (HFs). Little is known about the availability and the experience of differentiated HIV care delivery in the rural areas of Zimbabwe.Methods: We used a mixed-method approach to collect data from clients and providers at 26 HFs in Zimbabwe in 2019. We collected quantitative data about antiretroviral therapy (ART) delivery and time spent at the HF during a visit from one representative healthcare providers (HCP) and a stratified sample of PLWH at each HF. We performed semi-structured interviews among HCPs and focus group discussions (FGDs) among PLWH to collect information about the implementation of differentiated ART delivery (DART) models and their experience. We performed linear regression models to assess factors associated with the time spent in the HFs. We analyzed the interviews using an inductive approach. Transcripts were coded and constricted down to themes significant to the research objectives.Results: The majority (77%) of participating HFs offered at least one of the five DART models recommended in Zimbabwe: 13 (50%) offered community ART refill group (CARG), 1 (4%) club refill, 6 (23%) family refill, and 8 (31%) fast-track refill models. Mobile outreach was not available at any participating HF. In an unadjusted linear model, PLWH enrolled in the fast-track refill model spent 0.40 (95% confidence interval (CI): 0.15-0.56) less time at the HF than PLWH on routine care, whereas PLWH in the family refill model and delegated to go to the HF spent 2.63 (95% CI 1.42-4.88) more time at the HF during visit. Confidentiality and disclosure concerns were highlighted as the major barriers affecting the implementation of DART models, together with travel costs and waiting times. HCPs reported on the challenge of excessive workloads. Fast-track refill was perceived as the most adapted DART model to meet clients’ needs, followed by CARG and family refill.Conclusions: Confidentiality, travel costs and waiting times are key elements to consider in the implementation of differentiated care in rural Zimbabwe. More implementation research is needed to support the roll-out of differentiated HIV services in that region, especially DART models addressing the needs of PLWH. Our study supports the call for personalized care at ART programs in rural Africa.
