Dimensions for VA is a web-based tool available to VA staff that enables detailed searches of published research and research projects. OBJECTIVES: To examine the relationship between features of nursing home (NH) medical staff organization and residents' 30-day rehospitalizations. DESIGN: Cross-sectional study combining primary data collected from a survey of medical directors, NH resident assessment data (minimum data set), Medicare claims, and the Online Survey Certification and Reporting (OSCAR) database. SETTING: A total of 202 freestanding US nursing homes. PARTICIPANTS: Medicare fee-for-service beneficiaries who were hospitalized and subsequently admitted to a study nursing home. MEASUREMENTS: Medical staff organization dimensions derived from the survey, NH residents' characteristics derived from minimum data set data, hospitalizations obtained from Part A Medicare claims, and NH characteristics from the OSCAR database and from www.ltcfocus.org. Study outcome defined within a 30-day window following an index hospitalization: rehospitalized, otherwise died, otherwise survived and not rehospitalized. RESULTS: Thirty-day rehospitalizations occurred for 3788 (20.3%) of the 18,680 initial hospitalizations. Death was observed for 884 (4.7%) of residents who were not rehospitalized. Adjusted by hospitalization, resident, and NH characteristics, nursing homes having a more formal appointment process for physicians were less likely to have 30-day rehospitalization (b = -0.43, SE = 0.17), whereas NHs in which a higher proportion of residents were cared for by a single physician were more likely to have rehospitalizations (b = 0.18, SE = 0.08). CONCLUSION: This is the first study to show a direct relationship between features of NH medical staff organization and resident-level process of care. The relationship of a more strict appointment process and rehospitalizations might be a consequence of more formalized and dedicated medical practice with a sense of ownership and accountability. A higher volume of patients per physician does not appear to improve quality of care.
