Is there an association between surgeon hat type and 30-day wound events following ventral hernia repair?

While several patient and operative variables have been shown to be associated with an increased risk of postoperative wound events, the association between surgical hat type worn by surgeons and postoperative wound events remains controversial. The purpose of this study is to investigate the association between type of surgical hat worn by surgeons and the incidence of postoperative wound events following ventral hernia repair using the Americas Hernia Society Quality Collaborative database.

All surgeons who input at least ten patients with 30-day follow-up into the AHSQC were identified. These surgeons were sent a survey asking them to identify the type of surgical hat they wear in the operating room. The association of the type of surgical hat worn, patient variables, and operative factors with 30-day wound events was investigated using multivariate logistic regression.

A total of 68 surgeons responded to the survey, resulting in 6210 cases available for analysis. The type of surgical hat worn by surgeons was not found to be associated with an increased risk of 30-day surgical site infections or surgical site occurrences requiring procedural intervention.

Our study is the first study to directly compare the association of surgical hat type with postoperative wound events. There is no association between the type of surgical hat worn and the incidence of postoperative wound events following ventral hernia repair. Our findings suggest that surgical hate type may be chosen at the discretion of operating room personnel without fear of detriment to their patients.
