The authors use the State Inpatient Databases from the Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, provided by the Florida Agency for Healthcare Administration and the New York State Department of Health. The authors also use the American Hospital Association Annual Survey Databases. The authors thank Jean Roth at the National Bureau of Economic Research for assistance with the data; and three physicians for helping them learn the institutional details about hospital discharge. John Bowblis and the participants at the 2018 ASHEcon conference, the 2018 Bates White Life Science Symposium, the 2019 Midwest Health Economics Conference, and the 2019 UNC Healthcare Workshop have provided valuable comments on an earlier draft titled, “Medicare Payment to Skilled Nursing Facilities: The Consequences of the Medicare Three-Day Rule.” All errors are the authors’.
