In a series of reports, the Agency for Healthcare Research and Quality (AHRQ) has summarized evidence in support of eight quality improvement strategies: bundled payments; patient-centered medical homes; reduction of health disparities; medication adherence; public reporting; prevention of health care–associated infections; outcomes measurement for people with disabilities; and improvement of health care and palliative care for advanced illness. The free report series, Closing the Quality Gap: Revisiting the State of the Science, is available from the AHRQ website or by calling 1-800-358-9295 or emailing [email protected].
