Objective To examine if there were circadian variations in surgeons' ability to diagnose acute appendicitis. Design Retrospective database study of all patients admitted to an acute surgical procedure under the potential diagnosis of acute appendicitis in a 4-year period. The day was divided into 2 time intervals, day to evening hours (08:00-23:59) and night hours (00:00-07:59). Relevant data regarding the admission and surgical procedures were categorized into these 2 time intervals. Setting Department of Surgery at a Danish university hospital in Copenhagen. Participants A total of 2366 patients were included. There were no age limitations or selection in sex. Results There was no significant difference in the ability to diagnose appendicitis in day-evening hours vs night hours (p = 0.391), nor was any significant difference found on weekdays (Monday-Thursday) vs weekends (Friday-Sunday) (p = 0.278). There were no differences in duration of the procedures, rate of conversion, or severity of postoperative surgical complications between the 2 groups. More patients underwent diagnostic imaging during day to evening hours compared with night hours (308 vs 46; p = 0.014). The use of imaging had no effect on the ability to diagnose appendicitis. Male sex showed a higher probability of the diagnosis being appendicitis compared with other or no pathology (odds ratio: 3.094; p < 0.001). Age between 40 and 80 years was significantly associated with a higher probability of the diagnosis being appendicitis compared with other or no pathology. The negative appendectomy rate was 10.5%. Conclusion We found no difference in the surgeons' ability to diagnose acute appendicitis during night hours compared with day to evening hours.
