The relationship between surgical site infection and volume of coronary artery bypass graft surgeries: Taiwan experience.

In this study, the overall incidence of surgical site infection was 8.83% (3.28% for index hospitalization events [ie, events that occurred during hospitalization for surgery] and 5.55% for postdischarge events [ie, events that occurred within 30 days after discharge]). There was a negative association between surgical volume and the incidence of surgical site infection following coronary artery bypass graft surgery. The hospital volume has a greater effect than does surgeon volume on reducing the incidence of surgical site infection.
