  1. The association between the on-site availability of cardiac procedures and the utilization of those services for acute myocardial infarction by payer group.

    Article - En anglais

    Background 

    Prior studies have suggested that in-hospital availability may be an important determinant for the use of invasive cardiac services ; however, whether this association is influenced by payer status remains unclear.

    Hypothesis : The interaction of payer status and the on-site availability of coronary arteriography is associated with increased utilization of this procedure.

    Methods 

    In-hospital availability and utilization of coronary arteriography was ascertained in 275,046 patients with acute myocardial infarction (AMI) enrolled in the National Registry of Myocardial Infarction 2 from June 1994 to April 1996.

    Logistic regression analyses were performed to determine the association between the on-site availability of cardiac catheterization at the initial hospital and subsequent utilization of coronary arteriography.

    Similar analyses were performed within Medicare, Medicaid, Commercial, Health Maintenance Organization (HMO), and Uninsured payer groups.

    Results 

    Patients initially admitted to hospitals having on-site cardiac catheterization facilities were almost twice as likely to receive coronary arteriography as patients admitted to hospitals without such facilities and later transferred out [unadjusted odds ratio (OR)=1.69,95% confidence interval (CI) 1.66-1.73, p<0.0001 ; adjusted OR=2.08,95% CI 2.01-2.15, p<0.0001].
