Sun E, et al. - In this retrospective cohort study of 66,430 adults (aged 18 to 90 years) undergoing common operations, researchers determined the correlation between overlapping surgery (in which a primary surgeon is involved in more than 1 case simultaneously) and mortality, complications (major: thromboembolic event, pneumonia, sepsis, stroke, or myocardial infarction; minor: urinary tract or surgical site infection) and length of surgery. According to findings, overlapping surgery was significantly related to increased surgery length but was not significantly linked to differences in in-hospital mortality or postoperative complication rates among adults undergoing common operations.
