OBJECTIVE: To examine if there were circadian variations in surgeons' ability to diagnose @entity697 . DESIGN: Retrospective database study of all @entity1 admitted to an acute surgical procedure under the potential diagnosis of @entity697 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. @entity1 : A total of 2366 @entity1 were included. There were no age limitations or selection in sex. RESULTS: There was no significant difference in the ability to diagnose @entity698 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 @entity1 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 @entity698 . Male sex showed a higher probability of the diagnosis being @entity698 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 @entity698 compared with other or no pathology. The negative appendectomy rate was 10.5%. CONCLUSION: We found no difference in the surgeons' ability to diagnose @entity697 during night hours compared with day to evening hours.
