Key result
Admission to teaching hospitals for acute myocardial infarction during the first academic quarter was associated with a higher risk-adjusted mortality (OR 1.217) compared to other quarters.
Why the study?
Does admission to a teaching hospital during the first academic quarter increase mortality, cost, and length of stay for patients with myocardial infarction, heart failure, or pneumonia compared to other quarters or nonteaching hospitals?

Odds Ratio: 1.217 (95% CI 1.147–1.29)
Admission to teaching hospitals during the first academic quarter is associated with small increases in mortality for myocardial infarction and increased costs and length of stay for heart failure.
Mims et al. (2017) conducted an observational in Acute Myocardial Infarction, Heart Failure, or Pneumonia (n=544,617). Admission during the first academic quarter (July to September) in teaching hospitals vs. Admission during other quarters or in nonteaching hospitals was evaluated on Risk-adjusted mortality for acute myocardial infarction in the first academic quarter compared with other quarters (OR 1.217, 95% CI 1.147-1.290). Admission to teaching hospitals for acute myocardial infarction during the first academic quarter was associated with a higher risk-adjusted mortality (OR 1.217) compared to other quarters.
