Impact of hospital teaching status on survival from ruptured abdominal aortic aneurysm repair

In-hospital mortality rates for patients undergoing open abdominal aortic aneurysm repair for ruptured abdominal aortic aneurysm by hospital teaching status. Univariate comparison of mortality rates reveals P < .001.

Adjusted odds ratio of in-hospital mortality for patients undergoing open abdominal aortic aneurysm (AAA) repair of ruptured abdominal aortic aneurysm (rAAA) by hospital teaching status. Point estimate with 95% confidence intervals for risk of in-hospital death for patients undergoing open AAA repair for rAAA at each type of teaching hospital as compared to those hospitals lacking that type of hospital teaching status. Multi-level random effects multivariable logistic regression includes hospital teaching status, patient age, gender, race, Charlson index of comorbidities, and annual hospital volume of open AAA repair for rAAA.
