In this month's issue, Sessler et al. show absence of an association between the time of day at which scheduled (elective) general surgery and orthopedic procedures start and both 30-day risk-adjusted mortality and incidence of in-hospital complications. For start times between 7:00 AM and 5:00 PM, the confidence intervals for the odds ratios were narrow (i.e., unlikely that absence of an association was attributable to a type II error). These results are especially important because they differ from recent findings in gastrointestinal endoscopy. Sessler et al. also show no difference in patient outcome between July and August, when there are new trainees, and other months.
