Optimizing the timing of antimicrobial prophylaxis in surgery: an intervention study

Area of Science:

• Infectious Diseases
• Surgical Practice
• Hospital Pharmacy

Background:

• Surgical antimicrobial prophylaxis is crucial for preventing surgical site infections.
• Adherence to recommended timing and dosage protocols is often suboptimal.
• Improving prophylaxis practices can reduce antibiotic resistance and healthcare costs.

Purpose of the Study:

• To evaluate the impact of an educational intervention and new protocols on surgical antimicrobial prophylaxis timing.
• To assess the change in adherence to single-dose prophylaxis administered within one hour before incision.
• To compare prophylaxis timing in university hospital departments versus a community hospital.

Main Methods:

• Prospective study in three university hospital surgical departments and one community hospital.
• Intervention included surgeon, anesthetist, and nurse education on prophylaxis protocols.
• New protocols emphasized single-dose prophylaxis administered within one hour before incision.

Main Results:

• Adherence to prophylaxis within one hour before incision increased significantly in university departments (39% to 69% in Dept A, 64% to 80% in Dept B).
• Administration of prophylactic antibiotics before tourniquet inflation improved post-intervention.
• Single-dose prophylaxis use increased substantially (21% to 78% in Dept A, 31% to 85% in Dept B).

Conclusions:

• The educational intervention and protocol implementation successfully improved the quality of surgical antimicrobial prophylaxis.
• Enhanced adherence to timing and single-dose regimens contributes to better patient outcomes.
• Standardized prophylaxis protocols are effective in improving surgical care quality.
