Healthcare utilization following minimally invasive apical prolapse repair in a large integrated healthcare system.

INTRODUCTION AND HYPOTHESIS: We sought to describe healthcare utilization (HU) following minimally invasive apical prolapse repair (MIAR) and its association with duration of hospital stay, patient characteristics, and perioperative factors. METHODS: This retrospective study included women undergoing MIAR within a large managed care organization between January 1, 2011, and June 30, 2018, and aimed to quantify HU within 30 days of surgery. HU was dichotomized into two groups: normal and high, based on typical postoperative utilization of healthcare resources. The primary outcome was the rate of normal versus high HU overall and by duration of hospital stay [discharge home on day of surgery versus postoperative day (POD) 1-2]. Multivariable logistic regression was performed to identify factors predictive of high HU. A p value of < 0.05 was considered statistically significant. RESULTS: Of the 4208 patients in our final cohort, 17% had high HU, while 83% were normal utilizers. High utilizers were more likely to have multiple comorbidities (p < 0.01) and a diagnosis of chronic pelvic pain (p = 0.02) and were less likely to be discharged on day of surgery (p < 0.01). A higher burden of disease, a concurrent mid-urethral sling or posterior colporrhaphy, and discharge on POD 1-2 were independently predictive of high HU. Within the high HU cohort, the most common type of unanticipated healthcare encounter was emergency department visit for urinary retention or pain. CONCLUSIONS: Same-day discharge after MIAR does not result in increased HU, even after adjusting for relevant demographic and clinical characteristics. Pre-existing chronic pain diagnoses, multiple comorbidities, and concurrent mid-urethral sling are associated with high HU in this population.

Factors Associated With Long-Term Use of Percutaneous Tibial Nerve Stimulation for Management of Overactive Bladder Syndrome.

OBJECTIVES: The aims of the study were to estimate the rate of percutaneous tibial nerve stimulation maintenance therapy (PTNS-MT) among women with overactive bladder syndrome (OAB) and evaluate factors associated with long-term use of PTNS. METHODS: Patients who completed 12 weekly sessions of PTNS (PTNS-IN) for OAB between 2009 and 2016 within the Kaiser Permanente Northern California were identified using Current Procedural Terminology and International Classification of Diseases codes. Bivariate analysis was performed to compare demographic and clinical variables. A logistic regression model was used to determine factors associated with PTNS-MT compared with the use of alternative treatments following PTNS-IN. RESULTS: Of the 1331 patients who initiated PTNS for OAB, 347 (26%) completed PTNS-IN. Of these, 46% (n = 158) continued with long-term PTNS therapy, defined as completion of at least 8 additional PTNS sessions for a 32-week period. On bivariate analysis, those choosing PTNS-MT were more likely to be white (88%, P < 0.0001), nondiabetic (89%, P = 0.03), did not use anticholinergics before PTNS initiation (41%, P = 0.04), and had no prior surgery for stress incontinence (SUI; 84%, P = 0.01). In multivariable analysis, race was a significant factor with black, Hispanic, and Asian women less likely to continue with PTNS-MT. Women with prior use of first-line OAB therapy were 78% more likely to undergo PTNS-MT. Women with prior surgery for SUI were 53% less likely to continue PTNS-MT. CONCLUSIONS: Almost half of patients who completed PTNS-IN continued with PTNS-MT. White race, prior use of first-line OAB therapy, and no prior surgery for SUI were associated with long-term therapy.
