A Quality Assurance Initiative on Improving Cefazolin Peri-operative Redose Compliance

ABSTRACT
Background

Compliance with perioperative antibiotic prophylaxis is crucial for preventing surgical site infection. Anesthesiologists can play a significant role in reducing surgical site infections by following clinical practice guidelines for antibiotic prophylaxis and redosing during surgery. A quality assurance initiative was implemented at a tertiary hospital with the goal of improving cefazolin perioperative antibiotic compliance.

Methods

A multifaceted intervention was initiated to address low compliance with cefazolin redosing. Multifaceted interventions included the development of a perioperative antibiotic guide for anesthesia providers, automated reminders in anesthesia electronic medical records, grand rounds education, survey and email communications, and regular feedback reports to the anesthesia department.

Results

Rates of redose compliance were examined in three time periods: pre-intervention, intervention, and post-intervention. Cefazolin redosing compliance was 58% in the pre-intervention period and 90% in the post-intervention period. There was a significant positive change in the trend of compliance during the intervention period, indicating that the odds of compliance increased by 13% per month in the intervention period compared to the pre-intervention period (odds ratio = 1.13, p<0.001). Redose compliance improvements were sustained a year after the post intervention period (average 91%). Surgical site infection rates for colon, coronary artery bypass graft and hip surgeries did not show any significant trend during these time periods.

Conclusion

Multifaceted interventions led to significant and sustained improvements in cefazolin redosing compliance in the main operating room of a tertiary hospital.
