Understanding the Risk Factors of Trauma Center Closures: Do Financial Pressure and Community Characteristics Matter?
Hsia, Renee Y.
MetadataShow full item record
Objectives: We analyze whether hazard rates of shutting down trauma centers are higher due to financial pressures or in areas with vulnerable populations (such as minorities or the poor). Materials and Methods: This is a retrospective study of all hospitals with trauma center services in urban areas in the continental US between 1990 and 2005, identified from the American Hospital Association Annual Surveys. These data were linked with Medicare cost reports, and supplemented with other sources, including the Area Resource File. We analyze the hazard rates of trauma center closures among several dimensions of risk factors using discrete-time proportional hazard models.
