Abstract

Background: National guidelines recommend intraoperative redosing of prophylactic antibiotics at defined intervals to reduce the risk of surgical site infections. Compliance with these guidelines is poor. Methods: A quality improvement project—including education, progress reports, and automated redosing reminders in the anesthesia electronic health record—was implemented at a large university-affiliated hospital to increase rates of intraoperative antibiotic redosing for surgeries lasting more than 4 hours. A retrospective, observational study was then conducted. The primary outcome was the compliance rate with intraoperative antibiotic redosing criteria for all surgeries lasting more than 4 hours in the pre- and post-project period. The effect of the intervention was assessed by an interrupted time-series Poisson regression model. Results: A total of 13,695 surgical procedures were evaluated. Time-series analysis demonstrated that the project was associated with significant improvement of compliance rates (incidence rate ratio [IRR]: 1.16; P =.002) with no significant change in underlying improvement trend (IRR: 1.00; P =.22). Discussion: Few peer-reviewed manuscripts describe effective methods to ensure appropriate antibiotic redosing during prolonged surgeries. We demonstrated that a multipronged approach was very effective at producing immediate and sustained improvements in guideline compliance. Conclusions: Implementation of a multifaceted intervention improved rates of guideline-concordant redosing of intraoperative prophylactic antibiotics.
