This study examines temporal trends in the use and outcomes of cardiac procedures for patients hospitalized with acute myocardial infarction in Department of Veterans Affairs (VA) hospitals with and without invasive cardiac services. Between 1988 and 1994, there was striking overall growth in the use of cardiac procedures in the VA. Over this time period, the authors found persistent variation in the use of cardiac procedures but diminished differences in patient survival among patients admitted to different types of hospitals. Growth of cardiac procedure use and improvements in patient survival were most significant in hospitals without on-site invasive cardiac services. We were unable to determine whether survival gains were associated with increased procedure use or unmeasured improvements in the process of care. These trends raise intriguing questions about access to and outcomes of cardiac procedures in health systems composed of hospitals with and without a full complement of on-site invasive cardiac services.
