Objective: To determine whether postoperative cardiac care by cardiothoracic surgeons in a semiclosed intensive care unit model could be distinguished from that given by intensivists who are not board certified in cardiothoracic surgery.
Design: From January 2007 to February 2009, we retrospectively examined data on patients after cardiac operations from 2 consecutive periods during which full-time management of intensive care was changed from noncardiothoracic intensivists (period 1, 168 patients) to cardiothoracic surgeons (period 2, 272 patients).
Main outcome measures: Variables measured included Society of Thoracic Surgeons observed and expected mortality, central venous line infections, ventilator-acquired pneumonia, red blood cell exposure, adherence to blood glucose level target at 6 am on the first and second postoperative days, length of stay, and intensive care unit pharmacy costs. Results were compared using a 2-sample t test or 2-tailed Fisher exact test.
Results: In similar populations, as witnessed by equivalent Society of Thoracic Surgeons operative risk, cardiothoracic surgeons providing postoperative critical care led to a mean (SD) decrease in hospital length of stay from 13.4 (0.9) to 11.2 (0.4) days (P = .01) and decreased drug costs from $4300 (1000) to $1800 (200) (P < .001). These improvements occurred without losing benefits in other quality measures.
Conclusions: By virtue of their cardiac-specific operative and nonoperative training, cardiothoracic surgeons may be uniquely qualified to provide postoperative cardiac critical care. In a semiclosed unit where care of the patient is codirected, the improvements noted may have been facilitated by the commonalities between surgeons and intensivists associated with similar training and experiences.
