Does a case start time after 4:00 PM increase perioperative mortality in patients undergoing anesthesia?
A case start time after 4:00 PM, along with extremes of age and higher ASA physical status, is independently associated with increased perioperative mortality within 48 hours of anesthesia induction.
Whitlock et al. (2015) studied this question.
