Shared decision making for perioperative antibiotic use during Mohs micrographic surgery on the lower extremities

While there is a higher risk of surgical site infection (SSI) on the lower extremities following Mohs micrographic surgery (MMS), antibiotic prophylaxis (AP) is debated. To determine the role of shared decision making (SDM) in guiding AP usage during MMS on the lower extremities. A prospective observational study was conducted whereby patients received a standardized SDM discussion or routine counseling. Patient satisfaction quantified by the shared decision-making questionnaire (SDMQ9) survey, rate of SSI, and rate of AP prescription were recorded. In total, 51 patients were included. While there were less antibiotics prescribed in the treatment group (20% versus 50%, P = .025), this did not affect incidence of SSI (8% in treatment group versus 7.7% in control group, P = .668). Patient satisfaction was statistically greater in SDM group (4.73 versus 2.18 in control (P
