BACKGROUND: Aging beyond 65 years is associated with increased prevalence of urinary incontinence (UI), frailty, and increased complication rate with UI treatments. To investigate this relationship, we examined frailty as a predictor of procedure-based UI treatment patterns and urologic complications in Medicare-eligible women. METHODS: We identified women undergoing procedures for UI between 2011 and 2018 in the 5% limited Medicare data set. A claims-based frailty index (CFI) using data from the 12 months prior to the index procedure defined frailty (CFI ≥0.25). Urologic complications were assessed during the 12 months following the index procedure. We used unadjusted logistic regression models to calculate odds of having a specific type of UI procedure based on frailty status. Odds of postprocedure urologic complications were examined with logistic regression adjusted for age and race. RESULTS: We identified 21 783 women who underwent a procedure-based intervention for UI, of whom 3 826 (17.5%) were frail. Frail women with stress UI were 2.6 times more likely to receive periurethral bulking (95% confidence interval [CI] 2.26-2.95), compared to nonfrail. Conversely, frailty was associated with lower odds of receiving a Sling or Burch colposuspension. Among women with urgency UI or overactive bladder, compared to nonfrail, frailty was associated with higher odds of both sacral neuromodulation (odds ratio [OR] = 1.21, 95% CI: 1.11-1.33) and intravesical Botox (OR = 1.16, 95% CI: 1.06-1.28), but lower odds of receiving posterior tibial nerve stimulation. Frailty was associated with higher odds of postprocedure urologic complications (OR = 1.64, 95% CI: 1.47-1.81). CONCLUSIONS: Frailty status may influence treatment choice for treatment of stress or urgency UI symptoms and increase the odds of postprocedural complications in older women.
