Impact of Perioperative Antibiotic Prophylaxis Timing and Choice On Surgical Site Infection Rates in Clean and Clean-Contaminated Surgeries.

Abstract

Background: SSIs are a significant issue in surgical practice that prolongs hospital stay, hikes healthcare expenditures, and lowers morbidity in patients. Perioperative antibiotic prophylaxis (PAP) is essential in the prevention of SSIs, and the time and the type of antibiotics all have a big influence on infection predispositions. The study will evaluate the effect of antibiotic timing and choice on the rate of SSI in patients undergoing clean or clean-contaminated surgeries.

Objective: To assess the effects of the timing and the selection of perioperative antibiotic prophylaxis on the incidence of surgical site infections in both clean and clean-contaminated surgery, with a view to finding the best approaches to the prevention of SSIs.

Methodology: 100 patients who underwent either a clean or a clean-contaminated surgery. There were two groups of patients, time-sensitive ones (timely group) were allocated to antibiotic prophylaxis within 60 minutes before incision, whereas the attempt to administer antibiotics after the incision (delayed group). In clean surgeries, cefazolin was given, whereas surgeries with clean contamination were treated using second-generation cephalosporins with metronidazole. The SSI rates were followed within 30 days after surgery.

Results:The study found that the timely administration of antibiotics significantly reduced SSI rates. In clean surgeries, 4% of the timely group developed SSIs, compared to 12% in the delayed group. For clean-contaminated surgeries, the SSI rates were 6% in the timely group and 15% in the delayed group. The p-values for clean surgeries (0.02) and clean-contaminated surgeries (0.03) were statistically significant, indicating the importance of timely antibiotic prophylaxis in reducing infection rates.

Conclusion: antibiotic prophylaxis is an effective way of preventing SSIs in clean and contaminated surgeries and should be conducted on time. The results favour the existing evidence-based practices, which recommend the use of antibiotics early to achieve better surgical outcomes.
