The Housing and Accommodation Support Initiative (HASI) is a program funded by NSW Health and NSW Department of Housing, in partnership with nongovernment organisations (NGO). HASI provides a stable, consistent and integrated hospital to community care system for people with mental illness and associated psychiatric disability. This is achieved through providing practical assistance, intensive psychosocial support, clinical care and secure housing, along with opportunities, options and hope to people who have a mental illness (referred to here as consumers). This report examines the care planning practices of NGO Accommodation Support Providers (ASPs) in HASI Stage One. Funded by NSW Health, it extends a comprehensive evaluation of HASI One completed by the Social Policy Research Centre, (Muir et al, 2007). It has been undertaken as a result of the recommendations from that evaluation, which indicated the need to review and evaluate care planning in more detail. Methods included fieldwork in three of the nine HASI One sites (Section 1.1), including interviews with 20 consumers who participated in HASI, other people directly involved in their care planning, as well as an examination of their care plans.
