title: Prophylactic antibiotics for abdominal hysterectomy: indication for low-risk Canadian women.
abstract: OBJECTIVE
  To determine whether prophylactic antibiotics decrease the risk of infectious morbidity after total abdominal hysterectomy (TAH) in women at low risk for infection.
  
  
  METHODS
  An analysis of data from 1570 women undergoing planned TAH at 15 secondary and tertiary hospitals in Nova Scotia, Ontario, and Quebec, who agreed to participate in a centrally randomized controlled trial of vaginal antisepsis with povidone-iodine gel compared to no gel after the standard preoperative vaginal preparation with povidone-iodine solution.
  
  
  RESULTS
  Prophylactic antibiotics were used in 993 of 1570 women (63%). Appropriately timed prophylactic antibiotics decreased infectious morbidity (odds ratio [OR], 0.65; 95% confidence interval [CI], 0.50-0.85; P < .002). After controlling for risk factors for infection and study centre, the protective effect was even more pronounced (adjusted OR, 0.51; 95% CI, 0.36-0.73). Prophylactic antibiotics were associated with decreases in abdominal wound infection (OR, 0.45; 95% CI, 0.30-0.66) and pelvic infection (OR, 0.49; 95% CI, 0.26-0.92).
  
  
  CONCLUSIONS
  Women who did not receive prophylactic antibiotics had a higher surgical infection rate. Prophylactic antibiotics should be recommended for all women undergoing TAH.
