BACKGROUND: There is limited data on the incidence of postoperative infections following hysterectomy by route of surgery. We hypothesize that vaginal hysterectomy has lower rates of postoperative infection than laparoscopic and abdominal hysterectomies.
METHODS: A retrospective cohort study and independent hand review of charts of participants undergoing hysterectomy at five hospitals from September 2011 through May 2015 was performed. Cases were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes and were reviewed by the investigators. The primary outcome was the development of Clostridium difficile infection, urinary tract infection, surgical site infection, or yeast vaginitis within 60 days following surgery.
RESULTS: In total, 2742 women underwent hysterectomy: abdominal 17.5% (AH), laparoscopic 65.8% (LH), and vaginal 16.7% (VH). The composite postoperative infection rate for the four specified variables was 8.5% (232). In comparing surgical route, AH was most commonly associated with CDI (0.6%, p <0.001), SSI (6.0%, P=0.001), and yeast vaginitis (1.9%, p <0.001), while VH was most commonly associated with UTI (8.1%, P=0.002). After controlling for demographic and operative factors, multivariable analysis showed that hysterectomy route was not associated with infection. Independent predictors for postoperative infection were increasing age, American Society of Anesthesiologists physical status classification, operative time, and hospital type.
CONCLUSIONS: Infectious complications after hysterectomy are uncommon, accounting for 8.5% of cases. Multivariable analysis showed that demographic and operative variables were more likely to serve as independent predictors of development of infection than hysterectomy route.
