Aims and objectives To study risks of surgical site infection in breast surgery. The objectives were to measure the association of postoperative infection with patient‐ and procedure‐related factors. Background The infection rate in breast surgery is expected to be low but it varies a lot. The variation is recommended to be assessed by measuring procedure‐related factors. Design A retrospective chart review of 982 breast surgery patients was completed. Methods The data on patient demographics, procedure types, patient and surgery‐related factors were collected. A multivariate logistic regression model for all breast operations ( n = 982), lumpectomies ( n = 700) and mastectomies ( n = 282) was performed. Results The infection rate was 6·7%. In a multivariate logistic regression model for all operations, a contaminated or dirty wound, high A merican S ociety of A nesthesiologists score, high body mass index, use of surgical drains and re‐operation predicted increased infection risk. In lumpectomies high body mass index and use of surgical drains predicted increased risk. In mastectomies, the significant predictor was re‐operation. Conclusions The surgical site infection rate was high. In addition to the two classical risks (high wound class and anaesthesia risk), high body mass index, re‐operation and use of surgical drain increased the infection risk among all patients. Relevance to clinical practice In breast surgery careful assessment, documentation and adherence to aseptic practices are important with all patients. Patients with heavy weight need special attention. The need for antimicrobial prophylaxis in re‐operations and the need of surgical drains in lumpectomies are important to consider carefully.
