Postoperative Admission, Readmission, and Complications for Patients 60 Years and Older Who Are Undergoing an Isolated Sling Procedure for Stress Incontinence: A Database Study.

OBJECTIVE
The aim of the study was to determine the effect of increasing age on postoperative admission, readmission, and complications for patients 60 years and older who underwent a synthetic or autologous sling procedure for stress incontinence.


METHODS
A retrospective cohort study of surgical cases from 2012 to 2017 from the American College of Surgeons National Surgical Quality Improvement Program database was conducted. Eligible patients were at least 60 years old and underwent an isolated sling procedure for stress incontinence identified by Current Procedural Terminology code 57288. Baseline demographics, preoperative comorbidities, and postoperative complications were obtained. Risk ratios (RRs) and 95% confidence intervals were calculated using log-binomial regressions.


RESULTS
Of 3,960 eligible patients, 634 (16.0%) were admitted postoperatively. Admission rates differed across age groups (P = 0.04). For example, compared with patients aged 60-64 years, those aged 70-74 years had 1.3 times the risk of admission (95% confidence interval, 1.04-1.6). Other risk factors for admission included diabetes (RR, 1.3) and hypertension (RR, 1.2). Patients who had general anesthesia had 6.3 times the risk of admission compared with those who had monitored anesthesia/intravenous sedation. There were 72 patients (1.8%) readmitted within 30 days. There was no association between age and readmission. Risk factors for readmission included diabetes (RR, 1.8), bleeding disorders (RR, 3.4), severe chronic obstructive pulmonary disease (RR, 3.7), and congestive heart failure (RR, 11.3). There were 192 complications (4.8%), including 45 major complications (1.1%).


CONCLUSIONS
Among patients 60 years and older, the risk of postoperative admission and readmission for patients undergoing a synthetic or autologous sling procedure is low and complications are uncommon.
