Rethinking Perioperative Antibiotic Prophylaxis for Low-Risk Head and Neck Procedures.

Objective: For true clean-contaminated head and neck procedures, the literature supports ≤24 hours of perioperative antibiotics. However, there are certain otolaryngology procedures with low surgical site infection (SSI) risk for which there is negligible benefit from antibiotic prophylaxis. The objective of this evaluation was to describe antibiotic use and adherence to evidence-based institutional guidelines in low-risk head and neck procedures. Methods: This was a single-center, retrospective cohort study of patients undergoing low-risk clean-contaminated head and neck procedures wherein antibiotic prophylaxis was not indicated, based on evidence-based institutional guidelines. Results: Among the 291 included patients, perioperative antibiotics were unnecessarily administered in 29% of patients. Among patients who received antibiotics, 76% received preoperative antibiotics and 41% received postoperative antibiotics, for a median duration of 7 days. There were no significant differences in SSIs, mortality, and length of stay for those receiving perioperative antibiotics versus those not receiving perioperative antibiotics. Conclusion: These data highlight the need for antibiotic stewardship interventions and partnerships between antibiotic stewardship teams and surgical services. [ABSTRACT FROM AUTHOR]
