Improving the Timing of Antimicrobial Prophylaxis through a Total Quality Management Approach

Abstract

Studies have shown that the optimal time to give preoperative prophylactic antibiotics is within 2 hours prior to the incision. An initial study of perioperative antibiotic use at our institution revealed significant deficiencies both in the timing and the charting of preoperative antibiotics. In response to these findings, a multidisciplinary total quality management team was formed. This team identified several key problems related to the timing and documentation of preoperative antibiotics. Accordingly, our institution's method of prophylactic antibiotic delivery and administration was revised, and a program to educate appropriate staff was formulated. Following these interventions, a second study found that the number of preoperative antibiotic doses given at the proper time improved from 86% in the previous study to 98%, and that the number of doses properly charted improved from 84% to 94%.
