Key result
Initial admission to a major teaching hospital for AMI yielded no 30-day survival benefit versus nonteaching hospitals (OR 1.01; 95% CI 0.96-1.03).
Why the study?
Does admission to a teaching hospital improve 30-day mortality in Medicare patients with acute myocardial infarction compared to nonteaching hospitals?

Does admission to a teaching hospital improve 30-day mortality in Medicare patients with acute myocardial infarction compared to nonteaching hospitals?
Effect estimate: OR 1.01 (95% CI 0.96-1.03)
Initial admission to a teaching hospital for acute myocardial infarction does not confer a significant survival benefit over nonteaching hospitals when appropriately accounting for patient transfers and severity.
Navathe et al. (2013) conducted an observational in Acute myocardial infarction (AMI) (n=1,309,554). Admission to a teaching hospital vs. Admission to a nonteaching hospital was evaluated on 30-day all-cause, all-location mortality (OR 1.01, 95% CI 0.96-1.03). Initial admission to a major teaching hospital for AMI yielded no 30-day survival benefit versus nonteaching hospitals (OR 1.01; 95% CI 0.96-1.03).
