Differentiated Antiretroviral Therapy Delivery: Implementation Barriers and Enablers in South Africa.

Scale-up of antiretroviral therapy (ART) for people living with HIV requires differentiated models of ART delivery to improve access and contribute to achieving viral suppression for 95% of people on ART. We examined barriers and enablers in South Africa via semistructured interviews with 33 respondents (program implementers, nurses, and other health care providers) from 11 organizations. The interviews were recorded, transcribed, and analyzed for emerging themes using NVivo 11 software. Major enablers of ART delivery included model flexibility, provision of standardized guidance, and an increased focus on person-centered care. Major barriers were related to financial, human, and space resources and the need for time to allow buy-in. Stigma emerged as both a barrier and an enabler. Findings suggest that creating and strengthening models that cater to client needs can achieve better health outcomes. South Africa's efforts can inform emerging models in other settings to achieve epidemic control.
