Risk factors predicting the loss of functional independence after obliterative procedures for pelvic organ prolapse.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: To determine the risk factors associated with loss of functional independence after obliterative procedures for pelvic organ prolapse (POP). METHODS: The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database was used to collect data on women who underwent obliterative vaginal procedures from 2011 to 2016, using current procedural terminology (CPT) codes for LeFort colpocleisis (57120) and vaginectomy (57110). The criterion for loss of functional independence was a transition from a functionally independent status to a dependent status (discharge to a post-care facility) or death within the 30-day postoperative period. Multivariate regression analysis was utilized to determine factors associated with loss of functional independence. RESULTS: A total of 1847 women were included in the analysis. A loss of functional independence was noted in 50 of the 1847 women (2.6%). The women who suffered loss of functional independence were older than those who were independent postoperatively (mean age 79.3 years, SD 7.47 vs. 76.7 years, SD 8.1, respectively). On multiple logistic regression analysis, age ≥ 80 years (OR 2.8, 95% CI 1.4-5.5), American Society of Anesthesiologists (ASA) classification ≥ 3 (OR 2.3, CI 1.1-4.7) and length of stay ≥ 5 days (OR 15.2, 95% CI 6.2-37.1) remained significantly associated with an increased risk of loss of functional independence. CONCLUSIONS: Age ≥ 80 years, ASA classification ≥ 3 and longer length of stay are associated with an increased risk of loss of functional independence after an obliterative procedure for pelvic organ prolapse. Consideration of these factors during the preoperative decision-making process may help improve outcomes in this cohort.
