Improved Outcomes With Integrated Intensivist Consultation for Cardiac Surgery Patients

Abstract

This study examined the impact of integrated intensivist consultation in the immediate postoperative period on outcomes for cardiac surgery patients. A retrospective cohort study was conducted in 1711 adult cardiac surgery patients from a single quaternary care center in Minnesota. Outcomes were compared across 2 consecutive 2-year time periods reflecting an elective intensivist model (n = 801) and an integrated intensivist model (n = 910). Patients under the 2 models were comparable with respect to demographics, comorbidities, procedure types, and Society for Thoracic Surgery predicted risk of mortality score; however, patients in the earlier cohort were slightly older and more likely to have chronic kidney disease ( P = .003). Integrated intensivist involvement was associated with reduced postoperative ventilator time, length of stay (LOS), stroke, encephalopathy, and reoperations for bleeding (all P < .01) but was not associated with mortality. Intensivist integration into the postoperative care of cardiac surgery patients may reduce ventilator time, LOS, and complications but may not improve survival.
