Differentiated Care > Resources > Summary of published evidence

The evidence for differentiated models of ART delivery is summarized below and presented by model type: health care worker-managed groups, client-managed groups, facility-based individual, and out-of-facility based individual. Data from peer-reviewed publications and conference abstracts is included with links to original sources highlighted and available for download. Other published literature such as commentaries, country implementation and costing studies can be found here.

Evidence on health care worker-managed groups highlights improved client outcomes, both at individual sites and at scale, and suggests benefits to other client groups, including children, their caregivers and clients who previously had high viral loads.

Data from client-managed group models shows improved client outcomes with qualitative evidence supporting reduced costs and increased time savings.

The limited evidence for facility-based individual models suggests increased cost effectiveness for the health system, improved quality of care and improved client outcomes.

Out-of-facility individual models vary according to where in the community the services are provided, as well as what services are delivered and by whom. They can be divided into three categories: fixed community points, mobile outreach ART delivery, and home delivery.
