Abstract

As data and recommendations regarding antibiotic prophylaxis in dermatologic surgery vary, we tried to describe the effect of antibiotic prophylaxis (AP) in Mohs micrographic surgery (MMS) on infective endocarditis, prosthetic joint infection, and surgical site infection using a single-institution retrospective cohort study of antibiotic use (pre-/intra-operative, post-operative or none) among 2,364 patient encouters treated with MMS. Bivariate logistic regression was evaluated for associations between patient and operative characteristics, antibiotic use, and infectious complications. 85.8% of patients received no AP, 10.0% received post-operative AP, and 4.1% received pre-/intra-operative AP. The overall surgical site infection (SSI) rate was 1.3%. SSI did not differ between patients who received pre-/intra-operative prophylaxis, post-operative prophylaxis or no antibiotics. One patient receiving pre-/intra-operative prophylaxis developed SSI. Repairs involving porcine xenografts and interpolation/pedicle flaps were associated with increased SSI. In addition, there were no patients who post-operatively experienced an infected joint or infective endocarditis. Limitations include selection bias, use of observational retrospective data, low infection rates, single institution analysis, and possible omission of explanatory variables or confounders. There was no difference in rates of SSI when comparing MMS patients who received pre-/intra-operative, post-operative or no AP. There were no cases of infective endocarditis or infected prosthetic joint.
