One of the primary goals of differentiated service delivery (DSD) for HIV is to alleviate the burden of lifelong antiretroviral therapy - and clinical visits for clients. DSD responds to clients’ expectations and needs and thereby honors the principle of person-centredness. However, to truly fulfil its promise, DSD requires a dynamic healthcare system that acknowledges that health needs evolve over time – and provides flexible responses. Service delivery transition needs can be related to growing older with HIV, pregnancy status, clinical characteristics, but also client preferences or model availability. This satellite will focus on ways to support clients’ moves or transitions between models, as their health needs and preferences evolve. It will examine transitions from less-intensive to more intensive DSD models and vice versa, as well as transitions between DSD models of the same intensity. This session is addressed at clients, programme planners and implementers, researchers, as well as policy makers.
