We propose to perform this study in 26 nursing homes in Connecticut. This study takes advantage of the complementary skills and experience of a multidisciplinary research team with expertise in geriatric medicine, geriatric clinical pharmacology, chronic disease epidemiology, effective clinical communication, and gerontological nursing. This study will serve to extend prior collaborative AHRQ-funded research efforts focused on the long-term care setting, between investigators based at the University of Massachusetts Medical School and Qualidigm (formerly the Connecticut Peer Review Organization), a nationally recognized quality improvement organization with close links to nursing homes across the state of Connecticut.
