HARTZ, EVELYN M. KUHN, ZHONG YUAN, R. CLIFTON BAILEY, ALFRED A. RIMM] Objective: The study investigated the value of using national or regional data bases to examine care in a specific hospital. Data sources: The following data sources were included: (1) the results of the 1992 HCFA analysis of the index hospital for patients hospitalized in fiscal year 1990; (2) the 1989 Medicare Provider Analysis and Review (MEDPAR) file; and (3) clinical information from bypass surgery patients in Wisconsin and from the index hospital. Principal findings: The assessment of the mortality rates in the index hospital for all conditions combined and for CABG patients differed depending on what data base was used and how the data were analysed. The national data were most useful in establishing that the coding practices for all patients and the mortality rate for intraaortic balloon patients differed between the index hospital and other hospitals. The regional clinical data base for bypass surgery patients was used to establish that the high mortality rates for intra-aortic balloon patients were due to patient selection. Conclusions: National claims data must be analysed carefully before applying results to an individual hospital. Even a careful analysis is more for raising questions about care at a specific hospital rather than for reaching definitive conclusions. © 1995 Elsevier Science Ltd Articles nationallicence Bypass surgery nationallicence mortality rates nationallicence quality of hospital care nationallicence HARTZ ARTHUR J.
