An expert committee under the Science and Technology for Sustainability (STS) Program, in collaboration with the Board on Population and Public Health Practice (BPH), completed a report that assesses the evidence on the impact of permanent supportive housing (PSH) programs on improved health outcomes and health care costs for those experiencing chronic homelessness. The report offers 9 recommendations for actions to increase knowledge on the relationship of PSH and health to help address policy and program barriers that affect the ability to bring PSH to scale to address housing and health care needs.
