Abstract

BACKGROUND: Acute care surgeons operate during the day and night. Time of day or night may impact the outcome because of surgeon and team fatigue, operative delays, or other unmeasured factors. METHODS: We performed matched retrospective cohort study of patients undergoing operative intervention at night by acute care surgeons over 16 months. Cases were matched on case complexity, age, and sex to daytime cases. Other confounders including comorbidities, presenting characteristics, complications, and mortality were abstracted. Outcomes differences between day and night cases were compared. RESULTS: Night cases (115) were matched 1:1 to daytime cases. Groups had similar degrees of comorbidity. Those operated at night had trends toward more hypotension and sepsis. After controlling for confounders using conditional logistic regression, surgical care at night was a potent predictor of mortality (odds ratio 30.02; 95% CI 2.33 to 387.40; P = .009) but had little impact on morbidity (odds ratio 1.34; 95% CI .77 to 2.36; P = .303). CONCLUSIONS: Emergency operations performed at night by acute care surgeons may have dissimilar outcomes compared with day cases.
