The association between smoking status and post-operative complications in pelvic organ prolapse corrective surgeries.

introduction and hypothesisTobacco is a known risk factor for pelvic organ prolapse (POP) as well as postoperative complications in general surgery procedures. Very little is known regarding the impact of tobacco use on postoperative outcomes in POP-correcting procedures, however. We hypothesize that tobacco use will be associated with an increased risk of postoperative complications in these procedures.

methodsThis study utilized the National Surgical Quality Improvement Program (NSQIP) database for the years 2012-2020. Patients who underwent POP-correcting procedures were identified using current procedural terminology (CPT) codes. Baseline characteristics between the patient populations were compared using chi-square and one-way ANOVA tests as indicated. Binary logistic regression was used to evaluate the incidence of postoperative complications based on smoking status while controlling for demographic and clinical factors.

resultsThis study included 43,406 total patients, 39,614 non-smokers and 3792 smokers. Postoperative complications including deep wound infections (P < 0.001), intraperitoneal infections (P = 0.003), wound dehiscence (P = 0.014), urinary tract infections (P = 0.029), and hospital readmissions (P < 0.001) were significantly higher in patients who smoke than those who do not. Further evaluation of patients who did not undergo mesh placement intraoperatively and those who solely underwent vaginal procedures showed similar trends.

conclusionsThis study demonstrates a higher incidence of postoperative complications after POP-correcting procedures in patients with who smoke. Wound complications, urinary tract infections, and hospital readmission confer a considerable amount of risk to patient outcomes in addition to significant healthcare cost. Consideration should be given to smoking status in preoperative evaluation and counseling before these procedures.
