Evaluation of the POP-UP programme: a multicomponent model of care for people living with HIV with homelessness or unstable housing.

Objective: Homelessness is the greatest risk factor for HIV viremia in San Francisco. Innovative care models for people with HIV (PWH) with homelessness or unstable housing (HUH) are needed to address this inequity. We developed a novel low-barrier clinic-based program for PWH-HUH in an urban safety-net clinic ('POP-UP') and report outcomes on care engagement and viral suppression.
