Medicine versus Surgery / Anesthesiology Intensivists: a Retrospective Review and Comparison of Outcomes in a Mixed Medical-Surgical-Trauma ICU
BACKGROUND:
With various types of complex patients being treated in a mixed medical- surgical- trauma intensive care unit (ICU), we hypothesized that there should be no difference in patient mortality with respect to the core training of the intensivist.
METHODS:
We reviewed the cases of all patients admitted to a mixed medical-surgical-trauma ICU at a Canadian university teaching hospital in 2007. Patients were assigned to 1 of 2 treatment groups (internal medicine, surgery/anesthesiology) based on the treating intensivist's training. Our primary outcome was to compare patient mortality in the ICU between the groups. We used generalized estimating equations to determine 10-day mortality after admission to the ICU. A multivariate Cox hazard model was used to determine statistical significance and 95% confidence intervals (CIs) for 11- to 60-day mortality in the ICU.
RESULTS:
A total of 961 patients were admitted from January to December, 2007. We found no significant difference between the groups in 10-day mortality (odds ratio 0.73, 95% CI 0.46-1.18, p = 0.20) and 11- to 60-day mortality (hazard ratio 1.43, 95% CI 0.62-3.30, p = 0.40) after admission to the ICU.
CONCLUSION:
In a large university trauma centre that operates a mixed medicine- surgical-trauma ICU, there was no significant difference in mortality between patients managed by intensivists with core training in internal medicine and those managed by intensivists with training in surgery/anesthesiology.
