Effectiveness of a surgical wound surveillance program

Area of Science:

• Surgical Infection Prevention
• Hospital Epidemiology
• Public Health Surveillance

Background:

• Surgical site infections (SSIs) pose a significant risk to patient outcomes.
• Effective surveillance programs are crucial for monitoring and controlling SSIs.
• Previous methods lacked consistent daily observation and comprehensive reporting.

Purpose of the Study:

• To implement and evaluate a five-year surgical wound surveillance program.
• To systematically track and reduce the incidence of surgical wound infections.
• To provide monthly data on infection rates to surgical services.

Main Methods:

• A dedicated nurse-surveyor conducted daily observations of all surgical wounds.
• Wound inspections occurred on postoperative days 3 and 7, at discharge, and during follow-up.
• Cultures were obtained from infected wounds, and data were reported monthly.

Main Results:

• The surgical wound infection rate progressively declined over the five-year study period.
• The overall incidence of surgical site infections decreased from 3.5% to less than 1%.
• Infection rates were calculated by operation class for each surgical service and the hospital.

Conclusions:

• A structured, comprehensive surgical wound surveillance program is highly effective in reducing infection rates.
• Daily monitoring and direct reporting to surgical leadership enhance infection control.
• The findings underscore the importance of systematic data collection and dissemination in improving surgical outcomes.
