Estimated National Cost of Pelvic Organ Prolapse Surgery in the United States.

OBJECTIVE: To estimate the national cost of pelvic organ prolapse (POP) surgery in the United States. METHODS: In this cross-sectional, population-based study, we used the 2016-2018 Healthcare Cost and Utilization Project National Inpatient Samples and National Ambulatory Surgery Samples to identify patients undergoing POP surgery using International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes, ICD-10 procedural codes, and Current Procedural Terminology codes. Cost-to-charge ratios and weighted estimates were used to calculate nationwide costs. Descriptive analysis was used to identify the sociodemographic, clinical, and surgical characteristics of the population undergoing POP surgery. RESULTS: Between 2016 and 2018, there were 140,762 POP surgical cases annually with an annual national cost estimated at $1.523 billion per year. The median cost per procedure increased slightly from $8,837 in 2016 to $8,958 in 2018. Overall, 82.5% of the total surgeries and 78% of the total national costs associated with POP surgery came from the ambulatory setting over this time period. Of these surgeries, 44.7% included an apical repair, and 42.3% included a concomitant hysterectomy. The average age of the population was 62 years, and 20% of the total population receiving prolapse surgery were younger than age 50 years. CONCLUSION: The annual national cost associated with surgical correction of POP is substantial, and the majority of cases occur in an ambulatory setting. These findings will contribute to enhancing cost-effectiveness analyses and decision-making processes for both health care professionals and policymakers as the national population continues to age.

Approaches to developing de novo cancer population models to examine questions about cancer and race in bladder, gastric, and endometrial cancer and multiple myeloma: the Cancer Intervention and Surveillance Modeling Network incubator program.

BACKGROUND: We are developing 10 de novo population-level mathematical models in 4 malignancies (multiple myeloma and bladder, gastric, and uterine cancers). Each of these sites has documented disparities in outcome that are believed to be downstream effects of systemic racism. METHODS: Ten models are being independently developed as part of the Cancer Intervention and Surveillance Modeling Network incubator program. These models simulate trends in cancer incidence, early diagnosis, treatment, and mortality for the general population and are stratified by racial subgroup. Model inputs are based on large population datasets, clinical trials, and observational studies. Some core parameters are shared, and other parameters are model specific. All models are microsimulation models that use self-reported race to stratify model inputs. They can simulate the distribution of relevant risk factors (eg, smoking, obesity) and insurance status (for multiple myeloma and uterine cancer) in US birth cohorts and population. DISCUSSION: The models aim to refine approaches in prevention, detection, and management of 4 cancers given uncertainties and constraints. They will help explore whether the observed racial disparities are explainable by inequities, assess the effects of existing and potential cancer prevention and control policies on health equity and disparities, and identify policies that balance efficiency and fairness in decreasing cancer mortality.

Menopausal hormone therapy use and risk of ovarian cancer by race: the ovarian cancer in women of African ancestry consortium.

BACKGROUND: Most studies examining post-menopausal menopausal hormone therapy (MHT) use and ovarian cancer risk have focused on White women and few have included Black women. METHODS: We evaluated MHT use and ovarian cancer risk in Black (n = 800 cases, 1783 controls) and White women (n = 2710 cases, 8556 controls), using data from the Ovarian Cancer in Women of African Ancestry consortium. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association of MHT use with ovarian cancer risk, examining histotype, MHT type and duration of use. RESULTS: Long-term MHT use, ≥10 years, was associated with an increased ovarian cancer risk for White women (OR = 1.38, 95%CI: 1.22-1.57) and the association was consistent for Black women (OR = 1.20, 95%CI: 0.81-1.78, pinteraction = 0.4). For White women, the associations between long-term unopposed estrogen or estrogen plus progesterone use and ovarian cancer risk were similar; the increased risk associated with long-term MHT use was confined to high-grade serous and endometroid tumors. Based on smaller numbers for Black women, the increased ovarian cancer risk associated with long-term MHT use was apparent for unopposed estrogen use and was predominately confined to other epithelial histotypes. CONCLUSION: The association between long-term MHT use and ovarian cancer risk was consistent for Black and White women.

Projected impact of guidelines on incidence of venous thromboembolism after cesarean delivery in the United States.

BACKGROUND: There is large variation in recommended for postcesarean delivery venous thromboembolism (VTE) prophylaxis among commonly used guidelines. OBJECTIVES: The aim of the study is to estimate implications of adoption of VTE prevention guidelines for rates of receipt of VTE prophylactic therapy and VTE following cesarean delivery (CD). METHODS: We used administrative data from the 2015-2019 Nationalwide Readmissions Database to identify cesarean deliveries and rates of VTE stratified by risk factors, leading to different prophylactic strategies based on several national guidelines. We used input parameters from the literature to construct a hybrid decision tree/Markov model to project the implications of guideline adoption on VTE rates for the first 6 weeks following delivery. RESULTS: Adoption of either the 2011 American College of Obstetricians and Gynecologists or the 2018 American Society for Hematology guidelines would avert a relatively small proportion (5%) of VTE cases, albeit with little low-molecular-weight heparin (LMWH) use (87-115 doses per 1000 CD patients). The 2012 American College of Chest Physicians guidelines were predicted to be more effective at averting VTE (21.2% reduction) with more LMWH usage (570 doses per 1000 deliveries). The 2015 Royal College of Obstetricians and Gynaecologists guidelines and universal use of 6 weeks of LMWH would avert an even larger proportion of cases (37.4% and 57.6%, respectively), at the cost of much higher rates of LMWH utilization (7233 doses per 1000 patients and 38 648 doses per 1000 patients). CONCLUSIONS: Adoption of different guidelines would have notably varying implications for clinical practice and potential for alteration of the national rate of VTE following CD.

Ethnoracial Differences in Premenopausal Hysterectomy: The Role of Symptom Severity.

OBJECTIVE: To evaluate whether greater symptom severity can explain higher hysterectomy rates among premenopausal non-Hispanic Black compared with White patients in the U.S. South rather than potential overtreatment of Black patients. METHODS: Using electronic health record data from 1,703 patients who underwent hysterectomy in a large health care system in the U.S. South between 2014 and 2017, we assessed symptom severity to account for differences in hysterectomy rates for noncancerous conditions among premenopausal non-Hispanic Black, non-Hispanic White, and Hispanic patients. We used Poisson generalized linear mixed modeling to estimate symptom severity (greater than the 75th percentile on composite symptom severity scores of bleeding, bulk, or pelvic pain) as a function of race-ethnicity. We calculated prevalence ratios (PRs). We controlled for factors both contra-indicating and contributing to hysterectomy. RESULTS: The overall median age of non-Hispanic White (n=1,050), non-Hispanic Black (n=565), and Hispanic (n=158) patients was 40 years. The White and Black patients were mostly insured (insured greater than 95%), whereas the Hispanic patients were often uninsured (insured 58.9%). White and Black patients were mostly treated outside academic medical centers (nonmedical center: 63.7% and 58.4%, respectively); the opposite was true for Hispanic patients (nonmedical center: 34.2%). Black patients had higher bleeding severity scores compared with Hispanic and White patients (median 8, 7, and 4 respectively) and higher bulk scores (median 3, 1, and 0, respectively), but pain scores differed (median 3, 5, and 4, respectively). Black and Hispanic patients were disproportionately likely to have severe symptoms documented on two or more symptoms (referent: not severe on any symptoms) (adjusted PR [Black vs White] 3.02, 95% CI 2.29-3.99; adjusted PR [Hispanic vs White] 2.61, 95% CI 1.78-3.83). Although Black and Hispanic patients were more likely to experience severe symptoms, we found no racial and ethnic differences in the number of alternative treatments attempted before hysterectomy. CONCLUSION: We did not find evidence of overtreatment of Black patients. Our findings suggest potential undertreatment of Black and Hispanic patients with uterine-sparing alternatives earlier in their disease progression.

Maternal morbidity and mortality among patients with cancer at time of delivery.

BACKGROUND: Individuals with cancer during pregnancy are a medically complex patient population that is anticipated to grow. A better understanding of this population and patterns of risk at time of delivery would offer an opportunity for providers to mitigate maternal morbidity. OBJECTIVE: This study aimed to estimate the prevalence in the United States of concurrent cancer diagnoses at time of delivery by cancer type and associated maternal morbidity and mortality. STUDY DESIGN: Using the National Inpatient Sample, we identified delivery-associated hospitalizations between 2007 and 2018. Concurrent cancer diagnoses were classified using the Clinical Classifications Software. Main outcomes included severe maternal morbidity, as defined by the Centers for Disease Control and Prevention indicators, and mortality during delivery hospitalization. We calculated adjusted rates for cancer diagnosis at time of delivery and adjusted odds ratios of severe maternal morbidity and maternal death during hospitalization using survey-weighted multivariable logistic regression models. RESULTS: In this sample of 9,418,761 delivery-associated hospitalizations, 63 per 100,000 deliveries had a concurrent cancer diagnosis (95% confidence interval, 60-66; national weighted estimate, 46,654,042). The most common cancer types were breast cancer (8.4 per 100,000 deliveries), leukemia (8.4 per 100,000 deliveries), Hodgkin lymphoma (7.4 per 100,000 deliveries), non-Hodgkin lymphoma (5.4 per 100,000 deliveries), and thyroid cancer (4.0 per 100,000 deliveries). Patients with cancer were at significantly higher risk for any severe maternal morbidity (adjusted odds ratio, 5.25; 95% confidence interval, 4.73-5.83) and maternal death (adjusted odds ratio, 67.5; 95% confidence interval, 45.1-101.4). Risks of hysterectomy (adjusted odds ratio, 16.92; 95% confidence interval, 13.96-20.52), acute respiratory distress (adjusted odds ratio, 12.76; 95% confidence interval, 9.92-16.42), sepsis (adjusted odds ratio, 11.91; 95% confidence interval, 8.68-16.32), and embolism (adjusted odds ratio, 11.12; 95% confidence interval, 6.94-17.82) were particularly heightened among patients with cancer. Patients with leukemia, specifically, had the highest risk of adverse maternal outcomes (adjusted rate, 113 per 1000 deliveries; 95% confidence interval, 91-135 per 1000) when evaluating risk by cancer type. CONCLUSION: Patients with cancer are at markedly increased risk of maternal morbidity and all-cause mortality during delivery-associated hospitalization. Risk is distributed unevenly within this population, with certain cancer types carrying unique risks for specific morbidity events.

High rates of venous thromboembolism among deliveries complicated by cancer.

BACKGROUND: Venous thromboembolism (VTE) risk is increased independently by both cancer and pregnancy. OBJECTIVES: To estimate VTE risk in the postpartum period among patients delivering with a cancer diagnosis, stratified by cancer type and delivery route. METHODS: We performed a retrospective cohort study utilizing the large, all-payer Nationwide Readmissions Database from October 2015 through December 2020. We identified delivery hospitalizations, cancer diagnoses, and VTE using patient demographics and diagnosis codes. The primary outcome was VTE incidence at 42 and 330 days from delivery admission date, comparing patients with and without cancer diagnoses. A secondary analysis included VTE risk stratified by cancer diagnosis and delivery route. Outcomes were compared using inverse probability-weighted survival curves. RESULTS: The study population included 9 793 503 delivery hospitalizations (weighted estimate, 18 207 346), with a weighted estimate of 10 428 (0.06%) pregnant patients with cancer. Individuals with cancer were older, with higher rates of comorbid conditions, than those without cancer. VTE incidence in individuals with cancer at 42 and 330 days was 1.11% and 2.19%, respectively, vs 0.11% and 0.14%, respectively, in those without cancer. At 330 days, this finding was significant in both unadjusted (relative risk, 15.52; 95% CI, 11.54-19.51) and adjusted (relative risk, 9.68; 95% CI, 7.18-12.18) models. Stratification by cancer type and delivery route demonstrated elevated VTE risk across cancer types, with cesarean delivery conferring a greater risk. CONCLUSION: Cancer in pregnancy confers excess thromboembolic risk extending beyond the immediate postpartum period. Further study is needed to identify optimal VTE prophylactic strategies for this population.

Geographic variation in the rate and route of hysterectomy for benign disease in the USA: A retrospective cross-sectional study.

OBJECTIVES: To describe population rate of hysterectomy for benign disease in the USA, including geographic variation across states and Hospital Service Areas (HSAs; areas defined by common patient flows to healthcare facilities). DESIGN: Cross-sectional study. SETTING: Four US states including 322 HSAs. POPULATION: A total of 316 052 cases of hysterectomy from 2012 to 2016. METHODS: We compiled annual hysterectomy cases, merged female populations, and adjusted for reported rates of previous hysterectomy. We assessed small-area variation and created multi-level Poisson regression models. MAIN OUTCOME MEASURES: Prior-hysterectomy-adjusted population rates of hysterectomy for benign disease. RESULTS: The annual population rate of hysterectomy for benign disease was 49 per 10 000 hysterectomy-eligible residents, declining slightly over time, mostly among reproductive-age populations. Rates peaked among residents ages 40-49 years, and declined with increasing age, apart from an increase with universal coverage at age 65 years. We found large differences in age-standardised population rates of hysterectomy across states (range 42.2-69.0), and HSAs (range: overall 12.9-106.3; 25th-75th percentile 44.0-64.9). Among the non-elderly population, those with government-sponsored insurance had greater variation than those with private insurance (coefficient of variation 0.61 versus 0.32). Proportions of minimally invasive procedures were similar across states (71.0-74.8%) but varied greatly across HSAs (27-96%). In regression models, HSA population characteristics explained 31.8% of observed variation in annual rates. Higher local proportions of government-sponsored insurance and non-White race were associated with lower population rates. CONCLUSIONS: We found substantial variation in rate and route of hysterectomy for benign disease in the USA. Local population characteristics explained less than one-third of observed variation.

Potential Clinical and Economic Outcomes of Over-the-Counter Hearing Aids in the US.

Importance: Over-the-counter (OTC) hearing aids are now available in the US; however, their clinical and economic outcomes are unknown. Objective: To project the clinical and economic outcomes of traditional hearing aid provision compared with OTC hearing aid provision. Design, Setting, and Participants: This cost-effectiveness analysis used a previously validated decision model of hearing loss (HL) to simulate US adults aged 40 years and older across their lifetime in US primary care offices who experienced yearly probabilities of acquiring HL (0.1%-10.4%), worsening of their HL, and traditional hearing aid uptake (0.5%-8.1%/y at a fixed uptake cost of $3690) and utility benefits (0.11 additional utils/y). For OTC hearing aid provision, persons with perceived mild to moderate HL experienced increased OTC hearing aid uptake (1%-16%/y) based on estimates of time to first HL diagnosis. In the base case, OTC hearing aid utility benefits ranged from 0.05 to 0.11 additional utils/y (45%-100% of traditional hearing aids), and costs were $200 to $1400 (5%-38% of traditional hearing aids). Distributions were assigned to parameters to conduct probabilistic uncertainty analysis. Intervention: Provision of OTC hearing aids, at increased uptake rates, across a range of effectiveness and costs. Main Outcomes and Measures: Lifetime undiscounted and discounted (3%/y) costs and quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs). Results: Traditional hearing aid provision resulted in 18.162 QALYs, compared with 18.162 to 18.186 for OTC hearing aids varying with OTC hearing aid utility benefit (45%-100% that of traditional hearing aids). Provision of OTC hearing aids was associated with greater lifetime discounted costs by $70 to $200 along with OTC device cost ($200-$1000/pair; 5%-38% traditional hearing aid cost) due to increased hearing aid uptake. Provision of OTC hearing aids was considered cost-effective (ICER<$100 000/QALY) if the OTC utility benefit was 0.06 or greater (55% of the traditional hearing aid effectiveness). In probabilistic uncertainty analysis, OTC hearing aid provision was cost-effective in 53% of simulations. Conclusions and Relevance: In this cost-effectiveness analysis, provision of OTC hearing aids was associated with greater uptake of hearing intervention and was cost-effective over a range of prices so long as OTC hearing aids were greater than 55% as beneficial to patient quality of life as traditional hearing aids.

Patient and Surgery Characteristics of Inpatient Hysterectomies Among Transgender Individuals.

Purpose: The purpose of this study is to estimate population-based rates of inpatient hysterectomy and accompanying bilateral salpingo-oophorectomy by indication and evaluate surgical patient characteristics by indication, year, patient age, and hospital location. Methods: We used 2016 and 2017 cross-sectional data from the Nationwide Inpatient Sample to estimate the hysterectomy rate for individuals aged 18-54 years with a primary indication for gender-affirming care (GAC) compared to other indications. Outcome measures were population-based rates for inpatient hysterectomy and bilateral salpingo-oophorectomy by indication. Results: The population-based rate of inpatient hysterectomy for GAC per 100,000 was 0.05 (95% confidence interval [CI] = 0.02-0.09) in 2016 and 0.09 (95% CI = 0.03-0.15) in 2017. For comparison, the rates per 100,000 for fibroids were 85.76 in 2016 and 73.25 in 2017. Rates of bilateral salpingo-oophorectomy in the setting of hysterectomy were higher in the GAC group (86.4%) than in comparison groups (22.7%-44.1% for all other benign indications, 77.4% for cancer) across all age ranges. A higher rate of hysterectomies performed for GAC was done laparoscopically or robotically (63.6%) than other indications, and none was done vaginally, as opposed to comparison groups (0.7%-9.8%). Conclusion: The population-based rate for GAC was higher in 2017 compared to 2016 and low compared to other hysterectomy indications. Rates of concomitant bilateral salpingo-oophorectomy were more prevalent for GAC than for other indications at similar ages. The patients in the GAC group tended to be younger, insured, and most procedures occurred in the Northeast (45.5%) and West (36.4%).

Influenza Vaccination Implementation in Sri Lanka: A Cost-Effectiveness Analysis.

Influenza causes an estimated 3 to 5 million cases of severe illness annually, along with substantial morbidity and mortality, particularly in low- and middle-income countries (LMICs). Currently, Sri Lanka has no influenza vaccination policies and does not offer vaccination within the public healthcare sector. Therefore, we performed a cost-effectiveness analysis of influenza vaccine implementation for the Sri Lankan population. We designed a static Markov model that followed a population cohort of Sri Lankans in three age groups, 0-4, 5-64, and 65+ years, through two potential scenarios: trivalent inactivated vaccination (TIV) and no TIV across twelve-monthly cycles using a governmental perspective at the national level. We also performed probabilistic and one-way sensitivity analyses to identify influential variables and account for uncertainty. The vaccination model arm reduced influenza outcomes by 20,710 cases, 438 hospitalizations, and 20 deaths compared to no vaccination in one year. Universal vaccination became cost-effective at approximately 98.01% of Sri Lanka's 2022 GDP per capita (incremental cost-effectiveness ratio = 874,890.55 Rs/DALY averted; 3624.84 USD/DALY averted). Results were most sensitive to the vaccine coverage in the 5-64-year-old age group, the cost of the influenza vaccine dose in the 5-64-years-old age group, vaccine effectiveness in the under-5-years-old age group, and the vaccine coverage in the under-5-years-old age group. No value for a variable within our estimated ranges resulted in ICERs above Rs. 1,300,000 (USD 5386.15) per DALY adverted. Providing influenza vaccines was considered highly cost-effective compared to no vaccines. However, large-scale national studies with improved data are needed to better inform estimates and determine the impact of vaccination implementation.

Long-term health-related quality of life and symptom severity following hysterectomy, myomectomy, or uterine artery embolization for the treatment of symptomatic uterine fibroids.

BACKGROUND: Few studies have directly compared different surgical procedures for uterine fibroids with respect to long-term health-related quality of life outcomes and symptom improvement. OBJECTIVE: We examined differences in change from baseline to 1-, 2-, and 3-year follow-up in health-related quality of life and symptom severity among patients who underwent abdominal myomectomy, laparoscopic or robotic myomectomy, abdominal hysterectomy, laparoscopic or robotic hysterectomy, or uterine artery embolization. STUDY DESIGN: The COMPARE-UF registry is a multiinstitutional prospective observational cohort study of women undergoing treatment for uterine fibroids. A subset of 1384 women aged 31 to 45 years who underwent either abdominal myomectomy (n=237), laparoscopic myomectomy (n=272), abdominal hysterectomy (n=177), laparoscopic hysterectomy (n=522), or uterine artery embolization (n=176) were included in this analysis. We obtained demographics, fibroid history, and symptoms by questionnaires at enrollment and at 1, 2, and 3 years posttreatment. We used the UFS-QoL (Uterine Fibroid Symptom and Quality of Life) questionnaire to ascertain symptom severity and health-related quality of life scores among participants. To account for potential baseline differences across treatment groups, a propensity score model was used to derive overlap weights and compare total health-related quality of life and symptom severity scores after enrollment with a repeated measures model. For this health-related quality of life tool, a specific minimal clinically important difference has not been determined, but on the basis of previous research, a difference of 10 points was considered as a reasonable estimate. Use of this difference was agreed upon by the Steering Committee at the time when the analysis was planned. RESULTS: At baseline, women undergoing hysterectomy and uterine artery embolization reported the lowest health-related quality of life scores and highest symptom severity scores compared with those undergoing abdominal myomectomy or laparoscopic myomectomy (P<.001). Those undergoing hysterectomy and uterine artery embolization reported the longest duration of fibroid symptoms with a mean of 6.3 years (standard deviation, 6.7; P<.001). The most common fibroid symptoms were menorrhagia (75.3%), bulk symptoms (74.2%), and bloating (73.2%). More than half (54.9%) of participants reported anemia, and 9.4% women reported a history of blood transfusion. Across all modalities, total health-related quality of life and symptom severity score markedly improved from baseline to 1-year with the largest improvement in the laparoscopic hysterectomy group (Uterine Fibroids Symptom and Quality of Life: delta= [+] 49.2; symptom severity: delta= [-] 51.3). Those undergoing abdominal myomectomy, laparoscopic myomectomy, and uterine artery embolization also demonstrated significant improvement in health-related quality of life (delta= [+]43.9, [+]32.9, [+]40.7, respectively) and symptom severity (delta= [-]41.4, [-] 31.5, [-] 38.5, respectively) at 1 year, and the improvement persisted from baseline for uterine-sparing procedures during second (Uterine Fibroids Symptom and Quality of Life: delta= [+]40.7, [+]37.4, [+]39.3 SS: delta= [-] 38.5, [-] 32.0, [-] 37.7 and third year (Uterine Fibroids Symptom and Quality of Life: delta= [+] 40.9, [+]39.9, [+]41.1 and SS: delta= [-] 33.9, [-]36.5, [-] 33.0, respectively), posttreatment intervals, however with a trend toward decline in degree of improvement from years 1 and 2. Differences from baseline were greatest for hysterectomy; however, this may reflect the relative importance of bleeding in the Uterine Fibroids Symptom and Quality of Life, rather than clinically meaningful symptom recurrence among women undergoing uterus-sparing treatments. CONCLUSION: All treatment modalities were associated with significant improvements in health-related quality of life and symptom severity reduction 1-year posttreatment. However, abdominal myomectomy, laparoscopic myomectomy and uterine artery embolization indicated a gradual decline in symptom improvement and health-related quality of life by third year after the procedure.

A Comparative Analysis of Health-Related Quality of Life 1 Year Following Myomectomy or Uterine Artery Embolization: Findings from the COMPARE-UF Registry.

Objective: To compare 12-month post-treatment health-related quality of life (HR-QoL) and symptom severity (SS) changes among patients with symptomatic uterine fibroids (SUF) not seeking fertility and undergo a hysterectomy, abdominal myomectomy (AM), or uterine artery embolization (UAE). Materials and Methods: The Comparing Options for Management: Patient-Centered Results for Uterine Fibroids (COMPARE-UF) Registry is a multi-institutional prospective observational cohort study of patients treated for SUF. A subset of 1465 women 31-45 years of age, who underwent either hysterectomy (n = 741), AM (n = 446), or UAE (n = 155) were included in this analysis. Demographics, fibroid history, and symptoms were obtained by baseline questionnaires and at 1 year post-treatment. Results were stratified by all treatments and propensity score weighting to adjust for differences in baseline characteristics. Results: Women undergoing UAE reported the lowest baseline HR-QoL and highest SS scores (mean = 40.6 [standard deviation (SD) = 23.8]; 62.3 [SD = 24.2]) followed by hysterectomy (44.3 [24.3]; 59.8 [SD = 24.1]). At 12 months, women who underwent a hysterectomy experienced the largest change in both HR-QoL (48.7 [26.2]) and SS (51.9 [25.6]) followed by other uterine-sparing treatments. Propensity score weighting revealed all treatments produced substantial improvement, with hysterectomy patients reporting the highest HR-QoL score (92.0 [17.8]) compared with myomectomy (86.7 [17.2]) and UAE (82.6 [21.5]) (p < 0.0001). Similarly, hysterectomy patients reported the lowest SS scores (8.2 [15.1]) compared with myomectomy (16.5 [15.1]) and UAE (19.6 [17.5]) (p < 0.0001). Conclusion: All procedures showed improvement in HR-QoL and reduction in SS score at 12 months, hysterectomy showing maximum improvement. Of importance, at 12 months, patients who underwent either a myomectomy or UAE reported comparable symptom relief and HR-QoL. Clinicaltrials.Gov Identifier: NCT02260752.

Model-Projected Cost-Effectiveness of Adult Hearing Screening in the USA.

BACKGROUND: While 60% of older adults have hearing loss (HL), the majority have never had their hearing tested. OBJECTIVE: We sought to estimate long-term clinical and economic effects of alternative adult hearing screening schedules in the USA. DESIGN: Model-based cost-effectiveness analysis simulating Current Detection (CD) and linkage of persons with HL to hearing healthcare, compared to alternative screening schedules varying by age at first screen (45 to 75 years) and screening frequency (every 1 or 5 years). Simulated persons experience yearly age- and sex-specific probabilities of acquiring HL, and subsequent hearing aid uptake (0.5-8%/year) and discontinuation (13-4%). Quality-adjusted life-years (QALYs) were estimated according to hearing level and treatment status. Costs from a health system perspective include screening ($30-120; 2020 USD), HL diagnosis ($300), and hearing aid devices ($3690 year 1, $910/subsequent year). Data sources were published estimates from NHANES and clinical trials of adult hearing screening. PARTICIPANTS: Forty-year-old persons in US primary care across their lifetime. INTERVENTION: Alternative screening schedules that increase baseline probabilities of hearing aid uptake (base-case 1.62-fold; range 1.05-2.25-fold). MAIN MEASURES: Lifetime undiscounted and discounted (3%/year) costs and QALYs and incremental cost-effectiveness ratios (ICERs). KEY RESULTS: CD resulted in 1.20 average person-years of hearing aid use compared to 1.27-1.68 with the screening schedules. Lifetime total per-person undiscounted costs were $3300 for CD and ranged from $3630 for 5-yearly screening beginning at age 75 to $6490 for yearly screening beginning at age 45. In cost-effectiveness analysis, yearly screening beginning at ages 75, 65, and 55 years had ICERs of $39,100/QALY, $48,900/QALY, and $96,900/QALY, respectively. Results were most sensitive to variations in hearing aid utility benefit and screening effectiveness. LIMITATION: Input uncertainty around screening effectiveness. CONCLUSIONS: We project that yearly hearing screening beginning at age 55+ is cost-effective by US standards.

Estimated Monetary Value of Future Research Clarifying Uncertainties Around the Optimal Adult Hearing Screening Schedule.

Importance: Adult hearing screening is not routinely performed, and most individuals with hearing loss (HL) have never had their hearing tested as adults. Objective: To project the monetary value of future research clarifying uncertainties around the optimal adult hearing screening schedule. Design, Setting, and Participants: In this economic evaluation, a validated decision model of HL (DeciBHAL-US: Decision model of the Burden of Hearing loss Across the Lifespan) was used to simulate current detection and treatment of HL vs hearing screening schedules. Key model inputs included HL incidence (0.06%-10.42%/y), hearing aid uptake (0.54%-8.14%/y), screening effectiveness (1.62 × hearing aid uptake), utility benefits of hearing aids (+0.11), and hearing aid device costs ($3690). Distributions to model parameters for probabilistic uncertainty analysis were assigned. The expected value of perfect information (EVPI) and expected value of partial perfect information (EVPPI) using a willingness to pay of $100 000 per quality-adjusted life-year (QALY) was estimated. The EVPI and EVPPI estimate the upper bound of the dollar value of future research. This study was based on 40-year-old persons over their remaining lifetimes in a US primary care setting. Exposures: Screening schedules beginning at ages 45, 55, 65, and 75 years, and frequencies of every 1 or 5 years. Main Outcomes and Measures: The main outcomes were QALYs and costs (2020 US dollars) from a health system perspective. Results: The average incremental cost-effectiveness ratio for yearly screening beginning at ages 55 to 75 years ranged from $39 200 to $80 200/QALY. Yearly screening beginning at age 55 years was the optimal screening schedule in 38% of probabilistic uncertainty analysis simulations. The population EVPI, or value of reducing all uncertainty, was $8.2 to $12.6 billion varying with willingness to pay and the EVPPI, or value of reducing all screening effectiveness uncertainty, was $2.4 billion. Conclusions and Relevance: In this economic evaluation of US adult hearing screening, large uncertainty around the optimal adult hearing screening schedule was identified. Future research on hearing screening has a high potential value so is likely justified.

Race Differences in the Associations between Menstrual Cycle Characteristics and Epithelial Ovarian Cancer.

BACKGROUND: Menstrual cycle characteristics-including age at menarche and cycle length- have been associated with ovarian cancer risk in White women. However, the associations between menstrual cycle characteristics and ovarian cancer risk among Black women have been sparsely studied. METHODS: Using the Ovarian Cancer in Women of African Ancestry (OCWAA) Consortium that includes 1,024 Black and 2,910 White women diagnosed with epithelial ovarian cancer (EOC) and 2,325 Black and 7,549 White matched controls, we investigated associations between menstrual cycle characteristics (age at menarche, age at menstrual regularity, cycle length, and ever missing three periods) and EOC risk by race and menopausal status. Multivariable logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Black women were more likely to be <11 years at menarche than White women (controls: 9.9% vs. 6.0%). Compared with ≥15 years at menarche, <11 years was associated with increased EOC risk for White (OR = 1.25; 95% CI, 0.99-1.57) but not Black women (OR = 1.10; 95% CI, 0.80-1.55). Among White women only, the association was greater for premenopausal (OR = 2.20; 95% CI, 1.31-3.68) than postmenopausal women (OR = 1.06; 95% CI, 0.82-1.38). Irregular cycle length was inversely associated with risk for White (OR = 0.78; 95% CI, 0.62-0.99) but not Black women (OR = 1.06; 95% CI, 0.68-1.66). CONCLUSIONS: Earlier age at menarche and cycle irregularity are associated with increased EOC risk for White but not Black women. IMPACT: Associations between menstrual cycle characteristics and EOC risk were not uniform by race.

Cost-effectiveness of Pulmonary Rehabilitation Among US Adults With Chronic Obstructive Pulmonary Disease.

Importance: Pulmonary rehabilitation (PR) after exacerbation of chronic obstructive pulmonary disease (COPD) is effective in reducing COPD hospitalizations and mortality while improving health-related quality of life, yet use of PR remains low. Estimates of the cost-effectiveness of PR in this setting could inform policies to improve uptake. Objective: To estimate the cost-effectiveness of participation in PR after hospitalization for COPD. Design, Setting, and Participants: This economic evaluation estimated the cost-effectiveness of participation in PR compared with no PR after COPD hospitalization in the US using a societal perspective analysis. A Markov microsimulation model was developed to estimate the cost-effectiveness in the US health care system with a lifetime horizon, 1-year cycle length, and a discounted rate of 3% per year for both costs and outcomes. Data sources included published literature from October 1, 2001, to April 1, 2021, with the primary source being an analysis of Medicare beneficiaries living with COPD between January 1, 2014, and December 31, 2015. The analysis was designed and conducted from October 1, 2019, to December 15, 2021. A base case microsimulation, univariate analyses, and a probabilistic sensitivity analysis were performed. Interventions: Pulmonary rehabilitation compared with no PR after COPD hospitalization. Main Outcomes and Measures: Net cost in US dollars, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio. Results: Among the hypothetical cohort with a mean age of 76.9 (age range, 60-92) years and 58.6% women, the base case microsimulation from a societal perspective demonstrated that PR resulted in net cost savings per patient of $5721 (95% prediction interval, $3307-$8388) and improved quality-adjusted life expectancy (QALE) (gain of 0.53 [95% prediction interval, 0.43-0.63] years). The findings of net cost savings and improved QALE with PR did not change in univariate analyses of patient age, the Global Initiative for Obstructive Lung Disease stage, or number of PR sessions. In a probabilistic sensitivity analysis, PR resulted in net cost savings and improved QALE in every one of 1000 samples and was the dominant strategy in 100% of simulations at any willingness-to-pay threshold. In a 1-way sensitivity analysis of total cost, assuming completion of 36 sessions, a single PR session would remain cost saving to $171 per session and had an incremental cost-effectiveness ratio of $884 per session for $50 000/QALY and $1597 per session for $100 000/QALY. Conclusions and Relevance: In this economic evaluation, PR after COPD hospitalization appeared to result in net cost savings along with improvement in QALE. These findings suggest that stakeholders should identify policies to increase access and adherence to PR for patients with COPD.

Route of myomectomy and fertility: a prospective cohort study.

OBJECTIVE: To assess prospectively the association between the myomectomy route and fertility. DESIGN: Prospective cohort study. SETTING: The Comparing Treatments Options for Uterine Fibroids (COMPARE-UF) Study is a multisite national registry of eight clinic centers across the United States. PATIENT(S): Reproductive-aged women undergoing surgery for symptomatic uterine fibroids. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): We used life-table methods to estimate cumulative probabilities and 95% confidence intervals (CI) of pregnancy and live birth by the myomectomy route during 12, 24, and 36 months of follow-up (2015-2019). We also conducted 12-month interval-based analyses that used logistic regression to estimate odds ratios and 95% CIs for associations of interest. In all analyses, we used propensity score weighting to adjust for differences across surgical routes. RESULT(S): Among 1,095 women who underwent myomectomy (abdominal = 388, hysteroscopic = 273, and laparoscopic = 434), 202 reported pregnancy and 91 reported live birth during 36 months of follow-up. There was little difference in the 12-month probability of pregnancy or live birth by route of myomectomy overall or among women intending pregnancy. In interval-based analyses, adjusted ORs for pregnancy were 1.28 (95% CI, 0.76-2.14) for hysteroscopic myomectomy and 1.19 (95% CI, 0.76-1.85) for laparoscopic myomectomy compared with abdominal myomectomy. Among women intending pregnancy, adjusted ORs were 1.27 (95% CI, 0.72-2.23) for hysteroscopic myomectomy and 1.26 (95% CI, 0.77-2.04) for laparoscopic myomectomy compared with abdominal myomectomy. Associations were slightly stronger but less precise for live birth. CONCLUSION(S): The probability of conception or live birth did not differ appreciably by the myomectomy route among women observed for 36 months postoperatively.

Cost comparison of using reusable versus disposable equipment for retinopathy of prematurity screening rounds.

Retinopathy of prematurity (ROP) screening rounds have been linked to pathogen transmission and serious adverse outcomes in neonatal intensive care units (NICUs). Using Monte Carlo simulations, we found that it is more likely less expensive to use reusable than disposable equipment in NICUs of all levels for maintaining sterile equipment on ROP screening rounds.
