Registry study reveals on-site cardiac catheterization increases arteriography rates across heart attack patients, indicating insurance type moderates procedure access.

Key Points

To determine whether the association between in-hospital availability of cardiac catheterization and the utilization of coronary arteriography varies by patient insurance payer status following acute myocardial infarction.
Evaluated 275,046 patients with acute myocardial infarction enrolled in the National Registry of Myocardial Infarction 2 between June 1994 and April 1996.
Conducted multivariable logistic regression analyses across Medicare, Medicaid, Commercial, Health Maintenance Organization (HMO), and uninsured payer groups.
Patients admitted to hospitals with on-site catheterization were roughly twice as likely to receive coronary arteriography compared to those admitted to hospitals without on-site facilities (adjusted OR = 2.08, 95% CI 2.01–2.15, p < 0.0001; unadjusted OR = 1.69, 95% CI 1.66–1.73, p < 0.0001).
The increase in procedure utilization linked to on-site availability occurred in every payer group but was highest for Commercial insurance (OR = 2.19, 95% CI 2.07–2.31, p < 0.0001) and lowest for Medicaid (OR = 1.46, 95% CI 1.29–1.65, p < 0.0001), with intermediate odds for Uninsured (OR = 1.74), HMO (OR = 1.67), and Medicare (OR = 1.60) cohorts.
