Decreasing the incidence of surgical wound infections. Validation of a surveillance-notification program.
In an attempt to validate the observations of a previously published ten-year study of surgical wounds, we studied 8,474 wounds over an 18-month period using a protocol nearly identical to that of the previous study. Our study corroborated the following predictors of clean-wound infection: increasing duration of surgery, age less than 1 or greater than 50 years, increasing duration of preoperative hospitalization, use of drains, and shaving and emergency surgery. We failed to corroborate use of wound irrigation as a protective measure or time of preoperative shaving as a significant variable. Most importantly, we found a 42% reduction in the clean-wound infection rate during the study period (1.9% to 1.1%), adding support to the concept that a wound surveillance program with surgeon notification is both efficacious and cost-effective.
