Abstract

Study Objective: To compare the 30-day incidence of deep or organ-space and/or superficial incisional surgical site infections (SSIs) by the subtype of laparoscopic hysterectomy and to report on additional risk factors for SSIs following laparoscopic hysterectomy. Design: Retrospective cohort study. Setting: American College of Surgeons National Surgical Quality Improvement Program Database. Patients: Women undergoing laparoscopic hysterectomy from 2012 to 2014. Interventions: Women were stratified into 3 groups by the type of hysterectomy: total laparoscopic hysterectomy (TLH), laparoscopic-assisted vaginal hysterectomy (LAVH), and laparoscopic supracervical hysterectomy (LSCH). Demographic and clinical characteristics were compared for the 3 groups using the Kruskal-Wallis test or 1-way analysis of variance, where appropriate, for continuous variables and the chi-square or Fisher's exact test for categoric variables. Post hoc analyses were performed for multiple comparisons. Univariate analyses to examine the association with SSI were performed using the t test or Wilcoxon rank sum test as appropriate for continuous variables and the chi-square test or Fisher's exact test as appropriate for categoric variables. Significant variables on univariate analysis were included in a stepwise, backward multivariable logistic regression to identify the independent risk factors of SSI. Measurements and Main Results: In total, 46 755 women underwent laparoscopic hysterectomy. Most were classified as TLH (26 009, 56%), followed by LAVH (13 884, 30%), and LSCH (6862, 14%). The overall rate of 30-day deep or organ-space SSI was 1.8% (n = 445). Thirty-day deep or organ-space SSI was lower in women who underwent LSCH (0.6%) than in women who underwent TLH (1.0%) or LAVH (1.1%; p = .001), but there was no difference in the incidence of superficial incisional SSI (0.8%, 0.8%, and 0.8% for TLH, LAVH, and LSCH, respectively; p = .75). On multivariate regression analysis, LSCH remained independently associated with a decreased risk of deep or organ-space SSI (adjusted odds ratio, 0.60; 95% confidence interval, 0.43–0.84; p = .003). In addition, relative to the women who were discharged on the same day, women admitted for >24 hours had 2-fold increased odds of deep or organ-space SSI. Asian race, smoking, perioperative transfusion, dirty or infected cases, and American Society of Anesthesiologist class 3 were associated with increased odds for deep or organ-space SSI. Length of stay >24 hours and Native Hawaiian/Pacific Islander race were associated with increased odds of superficial incisional SSI. Conclusion: LSCH is associated with a decreased risk of deep or organ-space SSI compared with other subtypes of laparoscopic hysterectomy. Same-day discharge after laparoscopic hysterectomy is associated with decreased odds of SSI.
