Practice Patterns of Antibiotic Prophylaxis in Patients Undergoing Mastectomy: A Survey of Members of the American Society of Breast Surgeons.

Our results highlight the need for high-quality evidence based on which guidelines must be updated, and the need to familiarize surgeons with current guidelines.
