Since April 2005, the Hospital Quality Alliance (HQA), a public–private collaboration to improve the quality of care provided by the nation's hospitals, has been publicly reporting information on the quality of hospital care. The project team, under two prior Fund grants, demonstrated a large variation in quality across hospitals and medical conditions, an inverse relationship between performance on HQA measures and risk-adjusted mortality, and potential tradeoffs between quality and costs. In this third project, the team will incorporate an analysis of new patient experience measures added to the HQA database in spring 2008. The investigators will study performance on these new measures, analyze the relationship with measures of quality and cost, examine if and how measures of care coordination are associated with hospital readmissions, and describe changes in hospital performance since the HQA was launched.
