Appropriate antibiotic administration in elective surgical procedures: still missing the message

Area of Science:

• Surgical infection prevention
• Antibiotic stewardship
• Healthcare quality improvement

Background:

• Antibiotic prophylaxis is crucial for preventing surgical site infections.
• Inappropriate antibiotic use contributes to antimicrobial resistance and increased healthcare costs.
• Optimizing antibiotic prophylaxis guidelines is essential in elective surgical procedures.

Purpose of the Study:

• To evaluate the appropriateness of antibiotic prophylaxis in elective colorectal surgery, cholecystectomy, and inguinal hernia repair.
• To assess compliance with established guidelines for prophylactic antibiotic prescribing.
• To identify areas for improvement in antibiotic utilization in a tertiary referral center.

Main Methods:

• Retrospective cross-sectional study of 419 elective surgical cases (colorectal, cholecystectomy, inguinal hernia repair) from January 2000 to May 2002.
• Antibiotic administration appropriateness assessed against national and international guidelines.
• Analysis of antibiotic dose and duration compared to recommended practices.

Main Results:

• Antibiotics were given in 73% of cases, but only 41% received a single dose as recommended.
• Inappropriate prolonged prophylaxis occurred in 80% of colorectal, 52% of cholecystectomy, and 31% of inguinal hernia repair cases.
• Mean antibiotic duration varied significantly across procedure types, indicating inconsistent application of guidelines.

Conclusions:

• Antibiotic prophylaxis in elective surgery is frequently administered inappropriately, often with prolonged durations.
• Close surveillance of antibiotic utilization by a dedicated team (e.g., microbiologists, pharmacists) is necessary.
• Implementing targeted interventions can minimize inappropriate antibiotic administration and promote antimicrobial stewardship.
