Role of surgeon in length of stay in ICU after cardiac bypass surgery.
BACKGROUND
We presumed that the surgeon himself has an impact on the results after coronary artery bypass grafting (CABG) as there is no unique protocol for the discharge of post-operative cardiac patients at our institution. Therefore, we examined whether the surgeon himself has an impact on the intensive care unit (ICU) stay of isolated CABG patients.


METHODS
We prospectively studied a total of 570 consecutive patients undergoing elective CABG. Length of stay in the ICU was defined as the number of days in the ICU unit post-operatively. Seven operating surgeons were classified in 3 categories on the basis of the mean hospital stay of their patients (1, 2 and 3 if the mean total patients' stay in hospital was <8 days, between 8 to 10 days, and longer than 10 days; respectively). Using a multivariable regression model, we determined the independent predictors of length of stay in the ICU (> 48 hours) and examined the role of surgeon in this regard.


RESULTS
Incidence of post-operative arrhythmia and length of ICU stay were higher in the patients of surgeon category 3 than those of surgeon categories 1 and 2. Surgeon category 3 also operated on patients with higher EuroSCOREs than did surgeon categories 1 and 2. With the aid of a multivariable stepwise analysis, three variables were identified as independent predictors significantly associated with ICU length of stay: age, history of cerebrovascular accident, and surgeon category.


CONCLUSIONS
Surgeon category may independently predict a prolonged length of stay in the ICU. We suggest that a unique discharge protocol for post-CABG patients be considered to restrict the role of surgeon in the ICU stay of these patients.
