Long-Term Costs of Minimally Invasive Sacral Colpopexy Compared to Native Tissue Vaginal Repair With Concomitant Hysterectomy.

STUDY OBJECTIVE: To determine the long-term costs of hysterectomy with minimally invasive sacrocolpopexy (MISCP) versus uterosacral ligament suspension (USLS) for primary uterovaginal prolapse repair. DESIGN: A hospital-based decision analysis model was built using TreeAge Pro (TreeAge Software Inc, Williamstown, MA). Those with prolapse were modeled to undergo either vaginal hysterectomy with USLS or minimally invasive total hysterectomy with sacrocolpopexy (MISCP). We modeled the chance of complications of the index procedure, prolapse recurrence with the option for surgical retreatment, complications of the salvage procedure, and possible second prolapse recurrence. The primary outcome was cost of the surgical strategy. The proportion of patients living with prolapse after treatment was the secondary outcome. SETTING: Tertiary center for urogynecology. PATIENTS: Female patients undergoing surgical repair by the same team for primary uterovaginal prolapse. INTERVENTIONS: Comparison analysis of estimated long-term costs was performed. MEASUREMENTS AND MAIN RESULTS: Our primary outcome showed that a strategy of undergoing MISCP as the primary index procedure cost $19 935 and that undergoing USLS as the primary index procedure cost $15 457, a difference of $4478. Furthermore, 21.1% of women in the USLS group will be living with recurrent prolapse compared to 6.2% of MISCP patients. Switching from USLS to MISCP to minimize recurrence risk would cost $30 054 per case of prolapse prevented. Additionally, a surgeon would have to perform 6.7 cases by MISCP instead of USLS in order to prevent 1 patient from having recurrent prolapse. CONCLUSION: The higher initial costs of MISCP compared to USLS persist in the long term after factoring in recurrence and complication rates, though more patients who undergo USLS live with prolapse recurrence.

Urethral Bulking With Polyacrylamide Hydrogel Compared With Other Treatments for Stress Urinary Incontinence: A Cost-Effectiveness Analysis.

Our objective was to perform a cost-effectiveness analysis comparing polyacrylamide hydrogel urethral bulking with other surgical and nonsurgical treatments for stress urinary incontinence (SUI). We created a cost-effectiveness analysis using TreeAge Pro, modeling eight SUI treatments. Treatment with midurethral sling (MUS) had the highest effectiveness (1.86 quality-adjusted life-years [QALYs]), followed by polyacrylamide hydrogel (1.82 QALYs), with a difference (Δ 0.02/year) less than the minimally important difference for utilities of 0.03 annually. When the proportion of polyacrylamide hydrogel urethral bulking procedures performed in the office setting is greater than 58%, polyacrylamide hydrogel is a cost-effective treatment for SUI, along with pessary, pelvic floor physical therapy, and MUS. Although MUS is more effective and, therefore, the preferred SUI treatment, polyacrylamide hydrogel is a reasonable alternative depending on patient preferences and treatment goals.

Projecting future prolapse outcomes with induction of labor at 39 weeks: a decision analysis.

INTRODUCTION AND HYPOTHESIS: In 2018, the ARRIVE trial (A Randomized Trial of Induction Versus Expectant Management) concluded that routine induction of labor (IOL) at 39 weeks gestation decreases cesarean delivery risk, with slightly lighter birthweight infants. We debated whether routine IOL would improve, worsen, or not change POP risk compared with expectant management (EM). METHODS: We constructed a decision analysis model with a lifetime horizon where nulliparous women reaching 39 weeks underwent IOL or EM. Subsequent vaginal versus cesarean delivery varied based on prior deliveries for up to four births. Subsequent delivery prior to 39 weeks and distribution of gestational age, birthweight, and delivery mode between 24 and 39 weeks was modeled from national data. We modeled increased POP risk with increasing vaginal parity, forceps delivery, and weight of largest infant delivered vaginally, accounting for differential infant weights in each strategy. RESULTS: IOL and EM have similar population-wide POP risk (15.9% and 15.7% respectively). Among women with only spontaneous vaginal deliveries that reached 39 weeks or beyond, the prevalence of POP was 20% after one delivery and 29% after four deliveries, with no difference between groups. The cesarean rate was lower with IOL (27.8% versus 29.8%). Sensitivity analysis revealed no meaningful thresholds among the variables, supporting model robustness. CONCLUSION: While routine induction of labor at 39 weeks results in a meaningfully higher vaginal delivery rate, there was no increase in POP, possibly due to the protective effect of lower birthweight.

Cost-Utility Analysis of Midurethral Sling Timing Among Women Undergoing Prolapse Surgery.

IMPORTANCE: There are no guidelines regarding the ideal timing of midurethral sling (MUS) placement following prolapse repair. OBJECTIVE: The objective of this study was to estimate the cost-utility of concomitant MUS versus staged MUS among women undergoing apical suspension surgery for pelvic organ prolapse. STUDY DESIGN: Cost-utility modeling using a decision analysis tree compared concomitant MUS with staged MUS over a 1-year time horizon. The primary outcome was the incremental cost-effectiveness ratio (ICER). Six scenarios were modeled to estimate cost-utilities for women with preoperative overt, occult, or no stress urinary incontinence (SUI) who underwent either minimally invasive sacrocolpopexy or vaginal native tissue apical suspension. Possible complications of de novo overactive bladder, urinary retention requiring sling lysis, mesh exposure, and persistent SUI were included. Costs from a third-party payer perspective were derived from Medicare 2022 reimbursements. One-way sensitivity analyses were performed. RESULTS: Among women without preoperative SUI, staged MUS was the dominant strategy for both surgical routes with higher utility and lower costs. For women with either occult or overt SUI undergoing sacrocolpopexy or vaginal repair, concomitant MUS was cost-effective (ICER = $21,114-$96,536 per quality-adjusted life-year). Therefore, concomitant MUS is preferred for patients with preoperative SUI as higher costs were offset by higher effectiveness. One-way sensitivity analyses demonstrated that ICERs were most affected by probability of cure following MUS. CONCLUSIONS: A staged MUS procedure is the dominant strategy for women undergoing apical prolapse repair without preoperative SUI. In women with either overt or occult SUI, the ICER was below the willingness-to-pay threshold of $100,000 per quality-adjusted life-year, suggesting that concomitant MUS surgery is cost-effective.

Surgical correction of the genital hiatus at the time of sacrocolpopexy - a 7-year Markov analysis: a cost-effectiveness analysis.

INTRODUCTION AND HYPOTHESIS: To perform a cost-effectiveness analysis of concurrent posterior repair performed at the time of laparoscopic hysterectomy with sacrocolpopexy over a 7-year time period. We hypothesize it is not cost-effective to perform a posterior colporrhaphy. METHODS: We used TreeAge Pro® to construct a decision model with Markov modeling to compare sacrocolpopexy with and without concurrent posterior repair (SCP and SCP+PR) over a time horizon of 7 years. Outcomes included probability and costs associated with prolapse recurrence, prolapse retreatment, and complications including rectal injury, rectovaginal hematoma requiring reoperation, and postoperative dyspareunia. Cost-effectiveness was defined as an incremental cost-effectiveness ratio (ICER) calculated as ∆ costs /∆ effectiveness and the willingness to pay (WTP) was set at $100,000/QALY. RESULTS: Our model showed that SCP was the dominant strategy, with lower costs (-$ 2681.06) and higher effectiveness (+0.10) compared to SCP+PR over the 7-year period. In two-way sensitivity analyses, we varied the probability of prolapse recurrence after both strategies. Our conclusions would only change if the probability of recurrence after SCP was at least 29.7% higher than after SCP+PR. When varying the probabilities of dyspareunia for both strategies, SCP+PR only became the dominant strategy if the probability of dyspareunia for SCP+PR was lower than the rate of SCP alone. CONCLUSIONS: In this 7-year Markov cost-effectiveness analysis, SCP without concurrent PR was the dominant strategy. SCP+PR costs more with lower effectiveness than SCP alone, due to higher surgical cost of SCP+PR and higher probability of dyspareunia after SCP+PR.

Universal Urogynecologic Consultation and Screening for Fecal Incontinence in Pregnant Women With a History of Obstetric Anal Sphincter Injury: A Cost-Effectiveness Analysis.

IMPORTANCE: Obstetric anal sphincter injuries (OASIS) predispose for the development of fecal incontinence (FI), but management of subsequent pregnancy after OASIS is controversial. OBJECTIVE: We aimed to determine if universal urogynecologic consultation (UUC) for pregnant women with prior OASIS is cost-effective. STUDY DESIGN: We performed a cost-effectiveness analysis of pregnant women with a history of OASIS modeling UUC compared with no referral (usual care). We modeled the route of delivery, peripartum complications, and subsequent treatment options for FI. Probabilities and utilities were obtained from published literature. Costs using a third-party payer perspective were gathered from the Medicare physician fee schedule reimbursement data or published literature converted to 2019 U.S. dollars. Cost-effectiveness was determined using incremental cost-effectiveness ratios). RESULTS: Our model demonstrated that UUC for pregnant patients with prior OASIS was cost-effective. Compared with usual care, the incremental cost-effectiveness ratio for this strategy was $19,858.32 per quality-adjusted life-year, below the willingness to pay a threshold of $50,000/quality-adjusted life-year. Universal urogynecologic consultation reduced the ultimate rate of FI from 25.33% to 22.67% and reduced patients living with untreated FI from 17.36% to 1.49%. Universal urogynecologic consultation increased the use of physical therapy by 14.14%, whereas rates of sacral neuromodulation and sphincteroplasty increased by only 2.48% and 0.58%, respectively. Universal urogynecologic consultation reduced the rate of vaginal delivery from 97.26% to 72.42%, which in turn led to a 1.15% increase in peripartum maternal complications. CONCLUSIONS: Universal urogynecologic consultation in women with a history of OASIS is a cost-effective strategy that decreases the overall incidence of FI, increases treatment utilization for FI, and only marginally increases the risk of maternal morbidity.

Financial analysis of minimally invasive sacrocolpopexy compared with native tissue vaginal repair with concomitant hysterectomy.

INTRODUCTION: Minimally invasive sacrocolpopexy (MISCP) is increasingly used for uterovaginal prolapse, but comparative cost data of MISCP versus native tissue vaginal repair (NTR) are lacking. The objective was to determine the cost difference, from a hospital perspective, between MISCP and NTR performed with hysterectomy for uterovaginal prolapse. METHODS: This was a retrospective cohort study at a tertiary care center of women who underwent NTR or MISCP with concomitant hysterectomy in 2021. Hospital charges, direct and indirect costs, and operating margin (revenue minus costs) were obtained from Strata Jazz and compared using SPSS. RESULTS: A total of 82 women were included, 33 MISCP (25 robotic, 8 laparoscopic) versus 49 NTR. Demographic and surgical data were similar, except that MISCP had younger age (50.5 vs 61.1 years, p<0.01). Same-day discharge and estimated blood loss were similar, but operative time was longer for MISCP (204 vs 161 min, p<0.01). MISCP total costs were higher (US$17,422 vs US$13,001, p<0.01). MISCP had higher direct costs (US$12,354 vs US$9,305, p<0.01) and indirect costs (US$5,068 vs US$3,696, p<0.01). Consumable supply costs were higher with MISCP (US$4,429 vs US$2,089, p<0.01), but the cost of operating room time and staff was similar (US$7,926 vs US$7,216, p=0.07). Controlling for same-day discharge, anti-incontinence procedures and smoking, total costs were higher for MISCP (adjusted beta = US$4,262, p<0.01). Mean charges (US$102,060 vs US$97,185, p=0.379), revenue (US$22,214 vs US$22,491, p=0.929), and operating margin (US$8,719 vs US$3,966, p=0.134) were not statistically different. CONCLUSION: Minimally invasive sacrocolpopexy had higher costs than NTR; however, charges, reimbursement, and operating margins were not statistically significantly different between the groups.

Surgical cost of robotic-assisted sacrocolpopexy: a comparison of two robotic platforms.

IMPORTANCE: Robotic assistance in pelvic organ prolapse surgery can improve surgeon ergonomics and instrument dexterity compared with traditional laparoscopy but at increased costs. OBJECTIVE: To compare total costs for robotic-assisted sacrocolpopexy (RSC) between two robotic platforms at an academic medical center. METHODS: Retrospective cohort of Senhance (Ascensus) RSC between 1/1/2019 and 6/30/21 who were matched 2:1 with DaVinci (Intuitive) RSC. Primary outcome was total costs to hospital system; secondarily we evaluated cost sub-categories. Purchase costs of the robotic systems were not included. T-test, chi-square, and Fisher's exact tests were used. A multivariable linear regression was performed to model total costs adjusting for potential confounders. RESULTS: The matched cohort included 75 subjects. The 25 Senhance and 50 DaVinci cases were similar overall, with mean age 60.5 ± 9.7, BMI 27.9 ± 4.7, and parity 2.5 ± 1.0. Majority were white (97.3%) and postmenopausal (86.5%) with predominantly stage III prolapse (64.9%). Senhance cases had longer OR times (Δ = 32.1 min, p = 0.01). There were no differences in concomitant procedures, intraoperative complications, or short-term postoperative complications between platforms (all p > 0.05). On univariable analysis, costs were similar (Senhance $5368.31 ± 1486.89, DaVinci $5741.76 ± 1197.20, p = 0.29). Cost subcategories (medications, supplies, etc.) were also similar (all p > 0.05). On multivariable linear regression, total cost was $908.33 lower for Senhance (p = 0.01) when adjusting for operative time, estimated blood loss, concomitant mid-urethral sling, and use of the GelPoint mini port system. CONCLUSIONS: Despite longer operating times, total cost of robotic-assisted sacrocolpopexy was significantly lower when using the Senhance compared to the DaVinci system.

Salpingo-oophorectomy or surveillance for ovarian endometrioma in asymptomatic premenopausal women: a cost-effectiveness analysis.

BACKGROUND: The lifetime risk of ovarian cancer is 1.9% among women with endometriosis compared with 1.3% among the general population. When an asymptomatic endometrioma is incidentally discovered on imaging, gynecologists must weigh the procedural complications and the potential for subsequent surgical menopause against future ovarian pathology or cancer. OBJECTIVE: We aimed to determine if performing unilateral salpingo-oophorectomy is a more cost-effective strategy for the prevention of death than surveillance for asymptomatic endometriomas. STUDY DESIGN: We created a cost-effectiveness model using TreeAge Pro (TreeAge Software Inc; Williamstown, MA) with a lifetime horizon. Our hypothetical cohort included premenopausal patients with 2 ovaries who did not desire fertility. Those diagnosed with asymptomatic endometrioma underwent either unilateral salpingo-oophorectomy or surveillance (ultrasound 6-12 weeks after diagnosis, then annually). Our primary effectiveness outcome was mortality, including death from ovarian cancer or surgery and all-cause mortality related to surgical menopause (± hormone replacement therapy) if the contralateral ovary is removed. We modeled the probabilities of surgical complications, occult malignancy, development of contralateral adnexal pathology, surgical menopause, use of hormone replacement therapy, and development of ovarian cancer. The costs included surgical procedures, complications, ultrasound surveillance, hormone therapy, and treatment of ovarian cancer, with information gathered from Medicare reimbursement data and published literature. Cost-effectiveness was determined using the incremental cost-effectiveness ratio of Δ costs / Δ deaths with a willingness-to-pay threshold of $11.6 million as the value of a statistical life. Multiple 1-way sensitivity analyses were performed to evaluate model robustness. RESULTS: Our model demonstrated that unilateral salpingo-oophorectomy is associated with improved outcomes compared with surveillance, with fewer deaths (0.28% vs 1.50%) and fewer cases of ovarian cancer (0.42% vs 2.96%). However, it costs more than sonographic surveillance at $6403.43 vs $5381.39 per case of incidental endometrioma. The incremental cost-effectiveness ratio showed that unilateral salpingo-oophorectomy costs $83,773.77 per death prevented and $40,237.80 per case of ovarian cancer prevented. As both values were well below the willingness-to-pay threshold, unilateral salpingo-oophorectomy is cost-effective and is the preferred strategy. If unilateral salpingo-oophorectomy were chosen over surveillance for premenopausal patients with incidental endometriomas, 1 diagnosis of ovarian cancer would be prevented in every 40 patients and 1 death averted in every 82 patients. We performed 1-way sensitivity analyses for all input variables and determined that there were no reasonable inputs that would alter our conclusions. CONCLUSION: Unilateral salpingo-oophorectomy is cost-effective and is the preferred strategy compared with surveillance for the management of incidental endometrioma in a premenopausal patient not desiring fertility. It incurs fewer deaths and fewer cases of ovarian cancer with costs below the national willingness-to-pay thresholds.

Surgical Correction of the Genital Hiatus at the Time of Sacrocolpopexy-Are Concurrent Posterior Repairs Cost-Effective?

OBJECTIVE: The objective was to perform a cost-effectiveness analysis of posterior repair performed at the time of sacrocolpopexy (SCP). METHODS: We used TreeAge Pro to construct a decision model comparing laparoscopic hysterectomy with SCP with and without concurrent posterior repair (SCP and SCP + PR). Using a time horizon of 1 year, we modeled prolapse recurrence, prolapse retreatment, and complications, including rectal injury, rectovaginal hematoma requiring surgical take-back, and postoperative dyspareunia. Costs included index surgery, surgical retreatment, and complications. We modeled effectiveness as quality-adjusted life years (QALYs). Cost-effectiveness was defined using the incremental cost-effectiveness ratio and willingness to pay of $100,000/QALY. Sensitivity analyses were performed. RESULTS: Sacrocolpopexy was the dominant strategy with a cost of $65,714 and an effectiveness of 0.84. It was cost-effective at willingness to pay threshold less than $100,000/QALY. The SCP + PR costs more ($75,063) with lower effectiveness (0.83). The effectiveness of the 2 strategies was similar, differing only by 0.01 QALY, which is less than the minimally important difference for utilities. Tornado plots showed CEA results were most influenced by the cost of SCP, cost of SCP + PR, and probability of dyspareunia after SCP. In 1-way sensitivity analyses, the model outcome would change only if the cost of SCP was increased by 12.8% or if the cost of SCP + PR decreased by 14.5%. For dyspareunia, our model would only change if the probability of dyspareunia after SCP alone was 75.9% (base case, 18.6%), whereas the probability of dyspareunia after SCP + PR was 26.8%. CONCLUSION: In this cost-effectiveness analysis, SCP without concurrent PR was the dominant strategy.

Disparity in Medicare payments by gender and training track in female pelvic medicine and reconstructive surgery.

BACKGROUND: Gender disparities in medicine have been demonstrated in the past, including differences in the attainment of roles in administration and in physician income. OBJECTIVE: Our objective was to determine the differences in Medicare payments based on the provider gender and training track among female pelvic medicine and reconstructive surgeons. STUDY DESIGN: Medicare payments from the Provider Utilization Aggregate Files were used to determine the payments made by Medicare to urogynecologists. This database was merged with the National Provider Identifier registry with information on subspecialty training, years since graduation, and the geographic pricing cost index used for Medicare payment adjustments. Physicians with <90% female patients and those who graduated medical school <7 years ago in obstetrics and gynecology or <8 years ago in urology were excluded. The effects of gender, specialty of training, number of services provided, years of practice, and geographic pricing cost index on physician reimbursement were evaluated using linear mixed modeling. RESULTS: A total of 578 surgeons with female pelvic medicine and reconstructive surgery subspecialty training met the inclusion criteria. Of those, 517 (89%) were trained as gynecologists, whereas 61 (11%) were trained as urologists. Furthermore, 265 (51%) of the gynecology-trained surgeons and 39 (80%) of the urology-trained surgeons were women. Among the urology-trained surgeons, the median female surgeon was paid $85,962 and their male counterparts were paid $121,531 (41% payment difference). In addition, urology-trained female pelvic medicine and reconstructive surgery surgeons performed a median of 1135 services and their male counterparts performed a median of 1793 services (57% volume difference). Similarly, among gynecology-trained surgeons, the median female payment was $59,277 with 880 services performed, whereas male gynecology-trained surgeons received a median of $66,880 with 791 services performed, representing a difference of 12% in payments and 11% in services. With linear mixed modeling, male physicians were paid more than female physicians while controlling for specialty training, number of services performed, years of practice, and geographic pricing cost index (P<.001). CONCLUSION: Although Medicare payments are based on an equation, differences in reimbursement by physician gender exist in female pelvic medicine and reconstructive surgery with female surgeons receiving lower payments from Medicare. The differences in reimbursement could not be solely explained by differences in patient volume, area of practice, or years of experience alone, suggesting that, similar to other fields in medicine, female surgeons in female pelvic medicine and reconstructive surgery are not paid as much as their male counterparts.

Developing an Advanced Alternative Payment Model for Stress Urinary Incontinence.

ABSTRACT: Historically, our health care system has been based on a fee-for-service model, which has resulted in high-cost and fragmented care. The Center for Medicare & Medicaid Services is moving toward a paradigm in which health care providers are incentivized to provide cost-effective, coordinated, value-based care in an effort to control costs and ensure high-quality care for all patients. In 2015, the Medicare Access and Children's Health Insurance Program Reauthorization Act repealed the Sustainable Growth Rate and the fee-for-service model, replacing them with a 2-track system: Merit-based Incentive Payment System and the advanced Alternative Payment Model (aAPM) system. In 2016, the American Urogynecologic Society Payment Reform Committee was created and tasked with developing aAPMs for pelvic floor disorders. The purpose of this article is to describe the stress urinary incontinence aAPM framework, the data selected and associated data plan, and some of the challenges considered and encountered during the aAPM development.

Hysterectomy Versus Hysteropexy at the Time of Native Tissue Pelvic Organ Prolapse Repair: A Cost-Effectiveness Analysis.

OBJECTIVE: The aim of the study was to determine whether a hysterectomy at the time of native tissue pelvic organ prolapse repair is cost-effective for the prevention of endometrial cancer. METHODS: We created a decision analysis model using TreeAge Pro. We modeled prolapse recurrence after total vaginal hysterectomy with uterosacral ligament suspension (TVH-USLS) versus sacrospinous ligament fixation hysteropexy (SSLF-HPXY). We modeled incidence and diagnostic evaluation of postmenopausal bleeding, including risk of endometrial pathology and diagnosis or death from endometrial cancer. Modeled costs included those associated with the index procedure, subsequent prolapse repair, endometrial biopsy, pelvic ultrasound, hysteroscopy, dilation and curettage, and treatment of endometrial cancer. RESULTS: TVH-USLS costs US $587.61 more than SSLF-HPXY per case of prolapse. TVH-USLS prevents 1.1% of women from experiencing postmenopausal bleeding and its diagnostic workup. It prevents 0.95% of women from undergoing subsequent major surgery for the treatment of either prolapse recurrence or suspected endometrial cancer. Using our model, it costs US $2,698,677 to prevent one cancer death by performing TVH-USLS. As this is lower than the value of a statistical life, it is cost-effective to perform TVH-USLS for cancer prevention. Multiple 1-way sensitivity analyses showed that changes to input variables would not significantly change outcomes. CONCLUSIONS: TVH-USLS increased costs but reduced postmenopausal bleeding and subsequent major surgery compared with SSLF-HPXY. Accounting for these differences, TVH-USLS was a cost-effective approach for the prevention of endometrial cancer. Uterine preservation/removal at the time of prolapse repair should be based on the woman's history and treatment priorities, but cancer prevention should be one aspect of this decision.

A cost-minimization analysis of treatment options for postmenopausal women with dysuria.

BACKGROUND: Empiric therapy for urinary tract infection is difficult in postmenopausal women because of the higher rates of confounding lower urinary tract symptoms and differential resistance profiles of uropathogens in this population. OBJECTIVE: The objective of the study was to determine the least costly strategy for treatment of postmenopausal women with the primary complaint of dysuria. STUDY DESIGN: We performed a cost minimization analysis modeling the following clinical options: (1) empiric antibiotic therapy followed by urine culture, (2) urinalysis with empiric antibiotic therapy only if positive nitrites and leukocyte esterase, or (3) waiting for culture prior to initiating antibiotics. For all strategies we included nitrofurantoin, trimethoprim/sulfamethoxazole, fosfomycin, ciprofloxacin, or cephalexin. Pathogens included Escherichia coli, Enterococcus faecalis, Klebsiella pneumonaie, or Proteus mirabalis. Pathogens, resistance, treatment success, and medication side effects were specific to postmenopausal women. RESULTS: Cost minimization modeling with TreeAge Pro assumed 73.4% of urinary tract infections were caused by Escherichia coli with 24.4% resistance to nitrofurantoin, trimethoprim/sulfamethoxazole. With our assumptions, empiric antibiotics with nitrofurantoin, trimethoprim/sulfamethoxazole was the least costly approach ($89.64/patient), followed by waiting for urine culture ($97.04/patient). Except for empiric antibiotics with fosfomcyin, empiric antibiotics was always less costly than using urinalysis to discriminate antibiotic use. This is due to the cost of urinalysis ($38.23), high rate of both urinary tract infection (91%), and positive urinalysis (69.3%) with dysuria in postmenopausal women and resultant high rate of antibiotic use with or without urinalysis. Options with fosfomycin were the most expensive because of the highest drug costs ($98/dose), and tornado analyses showed fosfomycin cost was the most impactful variable for model outcomes. Sensitivity analyses showed empiric fosfomycin became the least costly option if drug costs were $25.80, a price still more costly than almost all modeled baseline drug costs. This outcome was largely predicated on low resistance to fosfomycin. Conversely, ciprofloxacin was never the least costly option because of higher resistance and side effect cost, even if the drug cost was $0. We modeled 91% positive urine culture rate in postmenopausal women with dysuria; waiting for the urine culture prior to treatment would be the least costly strategy in a population with a predicted positive culture rate of <65%. CONCLUSION: The least costly strategy was empiric antibiotics with nitrofurantoin and trimethoprim/sulfamethoxazole, followed by waiting on culture results. Local resistance patterns will have an impact on cost minimization strategies. Empiric fosfomycin would be least costly with reduced drug costs, even at a level at which drug costs were higher than almost all other antibiotics. In a population with high posttest probability of positive urine culture, urinalysis adds unnecessary cost. Antibiotic stewardship programs should continue efforts to decrease fluoroquinolone use because of high resistance, side effects, and increased cost.

Cystoscopy at the time of benign hysterectomy: a decision analysis.

BACKGROUND: Gynecologists debate the optimal use for intraoperative cystoscopy at the time of benign hysterectomy. Although adding cystoscopy leads to additional up-front cost, it may also enable intraoperative detection of a urinary tract injury that may otherwise go unnoticed. Prompt injury detection and intraoperative repair decreases morbidity and is less costly than postoperative diagnosis and treatment. Because urinary tract injury is rare and not easily studied in a prospective fashion, decision analysis provides a method for evaluating the cost associated with varying strategies for use of cystoscopy. OBJECTIVE: The objective of the study was to quantify costs of routine cystoscopy, selective cystoscopy, or no cystoscopy with benign hysterectomy. STUDY DESIGN: We created a decision analysis model using TreeAge Pro. Separate models evaluated cystoscopy following abdominal, laparoscopic/robotic, and vaginal hysterectomy from the perspective of a third-party payer. We modeled bladder and ureteral injuries detected intraoperatively and postoperatively. Ureteral injury detection included false-positive and false-negative results. Potential costs included diagnostics (imaging, repeat cystoscopy) and treatment (office/emergency room visits, readmission, ureteral stenting, cystotomy closure, ureteral reimplantation). Our model included costs of peritonitis, urinoma, and vesicovaginal/ureterovaginal fistula. Complication rates were determined from published literature. Costs were gathered from Medicare reimbursement as well as published literature when procedure codes could not accurately capture additional length of stay or work-up related to complications. RESULTS: From prior studies, bladder injury incidence was 1.75%, 0.93%, and 2.91% for abdominal, laparoscopic/robotic, and vaginal hysterectomy, respectively. Ureteral injury incidence was 1.61%, 0.46%, and 0.46%, respectively. Hysterectomy costs without cystoscopy varied from $884.89 to $1121.91. Selective cystoscopy added $13.20-26.13 compared with no cystoscopy. Routine cystoscopy added $51.39-57.86 compared with selective cystoscopy. With the increasing risk of injury, selective cystoscopy becomes cost saving. When bladder injury exceeds 4.48-11.44% (based on surgical route) or ureteral injury exceeds 3.96-8.95%, selective cystoscopy costs less than no cystoscopy. Therefore, if surgeons estimate the risk of injury has exceeded these thresholds, cystoscopy may be cost saving. However, for routine cystoscopy to be cost saving, the risk of bladder injury would need to exceed 20.59-47.24% and ureteral injury 27.22-37.72%. Model robustness was checked with multiple 1-way sensitivity analyses, and no relevant thresholds for model variables other than injury rates were identified. CONCLUSION: While routine cystoscopy increased the cost $64.59-83.99, selective cystoscopy had lower increases ($13.20-26.13). These costs are reduced/eliminated with increasing risk of injury. Even a modest increase in suspicion for injury should prompt selective cystoscopy with benign hysterectomy.

Responsiveness and minimally important difference of SF-6D and EQ-5D utility scores for the treatment of pelvic organ prolapse.

BACKGROUND: Utility preference scores are standardized, generic, health-related quality of life (HRQOL) measures that quantify disease severity and burden and summarize morbidity on a scale from 0 (death) to 1 (optimal health). Utility scores are widely used to measure HRQOL and in cost-effectiveness research. OBJECTIVE: To determine the responsiveness, validity properties, and minimal important difference (MID) of utility scores, as measured by the Short Form 6D (SF-6D) and EuroQol (EQ-5D), in women undergoing surgery for pelvic organ prolapse (POP). MATERIALS AND METHODS: This study combined data from 4 large, U.S., multicenter surgical trials enrolling 1321 women with pelvic organ prolapse. We collected condition-specific quality of life data using the Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ). A subset of women completed the SF6D; women in 2 trials also completed the EQ5D. Mean utility scores were compared from baseline to 12 months after surgery. Responsiveness was assessed using effect size (ES) and standardized response mean (SRM). Validity properties were assessed by (1) comparing changes in utility scores at 12 months between surgical successes and failures as defined in each study, and (2) correlating changes in utility scores with changes in the PFDI and PFIQ. MID was estimated using both anchor-based (SF-36 general health global rating scale "somewhat better" vs "no change") and distribution-based methods. RESULTS: The mean SF-6D score improved 0.050, from 0.705 ± 0.126 at baseline to 0.761 ± 0.131 at 12 months (P < .01). The mean EQ-5D score improved 0.060, from 0.810 ± 0.15 at baseline to 0.868 ± 0.15 at 12 months (P < .01). The ES (0.13-0.61) and SRM (0.13-0.57) were in the small-to-moderate range, demonstrating the responsiveness of the SF-6D and EQ-5D similar to other conditions. SF-6D and EQ-5D scores improved more for prolapse reconstructive surgical successes than for failures. The SF-6D and EQ-5D scores correlated with each other (r = 0.41; n = 645) and with condition-specific instruments. Correlations with the PFDI and PFIQ and their prolapse subscales were in the low to moderate range (r = 0.09-0.38), similar to other studies. Using the anchor-based method, the MID was 0.026 for SF-6D and 0.025 for EQ-5D, within the range of MIDs reported in other populations and for other conditions. These findings were supported by distribution-based estimates. CONCLUSION: The SF-6D and EQ-5D have good validity properties and are responsive, preference-based, utility and general HRQOL measures for women undergoing surgical treatment for prolapse. The MIDs for SF-6D and EQ-5D are similar and within the range found for other medical conditions.

A cost-effectiveness analysis of Onabotulinumtoxin A as first-line treatment for overactive bladder.

INTRODUCTION AND HYPOTHESIS: To determine if Onabotulinumtoxin A (Botox®) should be offered as a first-line therapy for the treatment of overactive bladder (OAB), even before prescribing anticholinergics. METHODS: We performed a cost-effectiveness analysis modeling the following clinical options: no treatment, non-selective anticholinergics, selective anticholinergics, and Botox®. The model timeframe was 2 years to allow Botox® reinjection and discontinuation of anticholinergics. Multiple efficacy levels included response improvement by < 50%, 50%, 75%, and 100%. Botox® reinjection was allowed at 6 months if < 50% efficacy. Botox® complications and anticholinergic side effects were noted. We modeled up to one medication switch. No crossover from Botox® to anticholinergics or vice versa was allowed, and failures remained with refractory untreated overactive bladder. Medical literature data were used for model parameter values. Costs are 2016 $US. RESULTS: Botox® costs more than non-selective anticholinergics and less than selective anticholinergics in models with and without refractory overactive bladder costs. Botox® had the highest effectiveness (1.763 quality-adjusted life years). Using incremental cost-effectiveness ratios, Botox® was found to be cost-effective in models with and without refractory costs ($12,428.75 and $14,437.01, respectively). In both models, Botox® cost less and was more effective than selective anticholinergics, which were "dominated." Over 2 years, subjects averaged 15.6 and 14.3 months on selective and non-selective anticholinergics, respectively, and patients averaged 2.2 Botox® injections. Model results were unchanged with variation of input parameter estimates in sensitivity analyses. CONCLUSIONS: Botox® is a cost-effective therapy for overactive bladder and should be further explored as a first-line option in the treatment paradigm.

The Impact of the Affordable Care Act on Urogynecologic Surgery Cancelation Rates.

OBJECTIVES: We examined the impact of the implementation of the Affordable Care Act (ACA) on female pelvic medicine and reconstructive surgery (FPMRS) surgical cancelation rates. METHODS: A retrospective cohort study was performed on patients scheduling FPMRS procedures 1 year before and after ACA implementation at a regional academic medical center. We compared cancelation rates as well as sociodemographic, surgical, and medical history data. Analysis included χ test, t test, and univariable and multivariable logistic regression. RESULTS: We included 746 subjects, 373 each before and after ACA implementation (January 2014). Subjects were 59.2 ± 14.0 years old, predominantly white (94.9%), employed (45.8%), and married (66.6%), with a body mass index of 28.8 ± 6.2. Subjects lived a median of 24 miles from the hospital. None of these were significant predictors of cancelations. Surgery cancelation rate was 17.1% and occurred 9 days before surgery.On univariable analysis, cancelation rates did not differ relative to the ACA (15.5% before vs 18.6% after; mean difference, 3.16%; 95% confidence interval [CI], -2.29% to 8.69%; P = 0.254). Only 3 variables impacted cancelation rate on univariable analysis: women whose surgery was scheduled for later in the week, liver/renal disease, and minor vs major surgery.On multivariable regression including variables with P < 0.20 as candidate variables, the same 3 variables remained significant. Cancelations increased with procedures scheduled later in the week (odds ratio [OR], 1.169 per day; 95% CI, 1.004-1.361) and liver or renal disease (OR, 2.342; 95% CI, 1.015-5.405). Major procedures had fewer cancelations (OR, 0.625; 95% CI, 0.414-0.943). The ACA implementation of still did not impact cancelations (OR, 1.230; 95% CI, 0.831-1.821). CONCLUSIONS: The implementation of the ACA did not impact FPMRS cancelation rates. Significant predictors of surgical cancelation included later day of the week, comorbid renal or liver disease, and performance of a minor procedure.
