Inappropriate use of antibiotics in patients undergoing gynecologic surgery.

We retrospectively examined prophylactic antibiotic use and documentation of wound classification in patients having gynecologic surgery at a tertiary hospital. Of the 326 cases reviewed, 175 (54%) received prophylactic antibiotics when not indicated according to guidelines of the American College of Obstetricians and Gynecologists. Antibiotic administration varied significantly (P < 0.02) among the different types of surgery, being given in 82% of laparoscopic cases, 35% of nonobstetrical dilation and curettage and operative hysteroscopy procedures, and 51% of open abdominal procedures. There were no recorded episodes of anaphylaxis or pseudomembranous colitis. In conclusion, antibiotic use is high among gynecologic surgeons at a tertiary hospital, but this use was unnecessary.
