Comparative Effectiveness of Uterine Leiomyoma Procedures Using a Large Insurance Claims Database.

ABSTRACT: OBJECTIVE:To compare risk of reintervention, long-term clinical outcomes, and health care utilization among women who have bulk symptoms from leiomyoma and who underwent the following procedures: hysterectomy, myomectomy, uterine artery embolization, and magnetic resonance-guided, focused ultrasound surgery. METHODS:This was a retrospective analysis of administrative claims from a large U.S. commercial insurance database. Women aged 18-54 years undergoing any of the previously mentioned leiomyoma procedures between 2000 and 2013 were included. We assessed the following outcome measures: risk of reintervention between uterine-sparing procedures, risk of other surgical procedures or complications of the index procedure, 5-year health care utilization, pregnancy rates, and reproductive outcomes. Propensity score matching along with Cox proportional hazard models were used to adjust for differences in baseline characteristics between study cohorts. RESULTS:Among the 135,522 study-eligible women with mean follow-up of 3.4 years, hysterectomy was the most common first-line procedural therapy (111,324 [82.2%]) followed by myomectomy (19,965 [14.7%]), uterine artery embolization (4,186 [3.1%]) and magnetic resonance-guided focused ultrasound surgery (47 [0.0003%]). Small but statistically significant differences were noted for uterine artery embolization and myomectomy in reintervention rate (17.1% compared with 15.0%, P=.02), subsequent hysterectomy rates (13.2% compared with 11.1%, P<.01) and subsequent complications from index procedures (18.1% compared with 24.6%, P<.001). During follow-up, women undergoing myomectomy had lower leiomyoma-related health care utilization, but had higher all-cause outpatient services. Pregnancy rates were 7.5% and 2.2% among myomectomy and uterine artery embolization cohorts, respectively (P<.001) with both cohorts having similar rates of adverse reproductive outcome (69.4%). CONCLUSIONS:Although the overwhelming majority of women having leiomyoma with bulk symptoms underwent hysterectomy as their first treatment procedure, among those undergoing uterine-sparing index procedures, approximately one seventh had a reintervention, and one tenth ended up undergoing hysterectomy during follow-up. Compared with women undergoing myomectomy, women undergoing uterine artery embolization had a higher risk of reintervention, lower risk of subsequent complications, but similar rate of adverse reproductive outcomes.

Project description:BackgroundTo the extent that outcomes are mediated through negative perceptions of generics (the nocebo effect), observational studies comparing brand-name and generic drugs are susceptible to bias favoring the brand-name drugs. We used authorized generic (AG) products, which are identical in composition and appearance to brand-name products but are marketed as generics, as a control group to address this bias in an evaluation aiming to compare the effectiveness of generic versus brand medications.Methods and findingsFor commercial health insurance enrollees from the US, administrative claims data were derived from 2 databases: (1) Optum Clinformatics Data Mart (years: 2004-2013) and (2) Truven MarketScan (years: 2003-2015). For a total of 8 drug products, the following groups were compared using a cohort study design: (1) patients switching from brand-name products to AGs versus generics, and patients initiating treatment with AGs versus generics, where AG use proxied brand-name use, addressing negative perception bias, and (2) patients initiating generic versus brand-name products (bias-prone direct comparison) and patients initiating AG versus brand-name products (negative control). Using Cox proportional hazards regression after 1:1 propensity-score matching, we compared a composite cardiovascular endpoint (for amlodipine, amlodipine-benazepril, and quinapril), non-vertebral fracture (for alendronate and calcitonin), psychiatric hospitalization rate (for sertraline and escitalopram), and insulin initiation (for glipizide) between the groups. Inverse variance meta-analytic methods were used to pool adjusted hazard ratios (HRs) for each comparison between the 2 databases. Across 8 products, 2,264,774 matched pairs of patients were included in the comparisons of AGs versus generics. A majority (12 out of 16) of the clinical endpoint estimates showed similar outcomes between AGs and generics. Among the other 4 estimates that did have significantly different outcomes, 3 suggested improved outcomes with generics and 1 favored AGs (patients switching from amlodipine brand-name: HR [95% CI] 0.92 [0.88-0.97]). The comparison between generic and brand-name initiators involved 1,313,161 matched pairs, and no differences in outcomes were noted for alendronate, calcitonin, glipizide, or quinapril. We observed a lower risk of the composite cardiovascular endpoint with generics versus brand-name products for amlodipine and amlodipine-benazepril (HR [95% CI]: 0.91 [0.84-0.99] and 0.84 [0.76-0.94], respectively). For escitalopram and sertraline, we observed higher rates of psychiatric hospitalizations with generics (HR [95% CI]: 1.05 [1.01-1.10] and 1.07 [1.01-1.14], respectively). The negative control comparisons also indicated potentially higher rates of similar magnitude with AG compared to brand-name initiation for escitalopram and sertraline (HR [95% CI]: 1.06 [0.98-1.13] and 1.11 [1.05-1.18], respectively), suggesting that the differences observed between brand and generic users in these outcomes are likely explained by either residual confounding or generic perception bias. Limitations of this study include potential residual confounding due to the unavailability of certain clinical parameters in administrative claims data and the inability to evaluate surrogate outcomes, such as immediate changes in blood pressure, upon switching from brand products to generics.ConclusionsIn this study, we observed that use of generics was associated with comparable clinical outcomes to use of brand-name products. These results could help in promoting educational interventions aimed at increasing patient and provider confidence in the ability of generic medicines to manage chronic diseases.

Project description:ImportanceAlthough a few studies have shown that mental health disorders (MHDs) are strongly associated with the 5-year survival and recurrence rates in patients with head and neck cancer (HNC), none have been replicated in a large-scale study.ObjectiveTo describe the prevalence of MHDs in patients with HNC and the potential associations with survival and recurrence using a large insurance claims database.Design, setting, and participantsThis retrospective cohort study assessed data queried from the MarketScan database from January 1, 2005, through December 31, 2014, for 52 641 patients with a diagnosis of HNC. To exclude patients with a preexisting HNC diagnosis or those with incomplete data, patients were included if they were in the database for at least 12 months before the index diagnosis and continuously enrolled. Data were analyzed from February 20, 2017, through January 22, 2019.Main outcomes and measuresTo compare the frequency of MHDs before and after diagnosis of HNC, χ2 tests for independence were used. Adjusted adds ratios (aORs) were obtained using multivariable logistic regression by comparing the prevalence of MHDs in patients with oral cavity cancer and those with other cancer sites in the head and neck.ResultsAmong the 52 641 patients included in the analysis (mean [SD] age, 51.31 [9.79] years), men (58.5%), patients aged 55 to 64 years (46.6%), and those from the South (40.3%) were most commonly affected by HNC. Oral cavity cancers (40.4%) were the most common type, followed by cancers of the oropharynx (19.2%) and larynx (15.5%). Of the various cancer sites, the OR for MHD prevalence was significantly increased in patients with cancers of the trachea compared with the oral cavity (2.11; 95% CI, 1.87-2.38). The prevalence of MHDs in patients with HNC increased to 29.9% compared with 20.6% before the cancer diagnosis. Specifically, women (adjusted OR, 1.58; 95% CI, 1.49-1.67) and patients with a history of tobacco use (adjusted OR, 1.42; 95% CI, 1.34-1.50) and alcohol use (adjusted OR, 1.56; 95% CI, 1.38-1.76) had significantly higher odds of MHDs after the diagnosis of HNC.Conclusions and relevanceAlthough the baseline MHD prevalence of 20.6% before the cancer diagnosis was close to the national average (17.9% according to the National Survey on Drug Use and Health), results of this study showed that it increased to 29.9% after the cancer diagnosis. Women and patients with a history of tobacco and alcohol use were most susceptible to being diagnosed with an MHD. There is an association between patients with HNC and an increased prevalence of MHDs after treatment compared with the general population.

Project description:Both the uterus and breasts have sex hormone dependence, yet there are few studies on the association between breast disease and uterine fibroids (UFs). The purpose of this study was to investigate the incidence of benign breast disease (BBD), carcinoma in situ (CIS), and breast cancer (BC) in women treated for UFs compared to women who were not treated for UFs. This retrospective cohort study used national health insurance data from January 1st, 2011, to December 31st, 2020. We selected women between 20 and 50 years old who (1) were treated for UFs (UF group) or (2) visited medical institutions for personal health screening tests without UFs (control group). We analyzed independent variables such as age, socioeconomic status (SES), region, Charlson comorbidity index (CCI), delivery status, menopausal status, menopausal hormone therapy (MHT), endometriosis, hypertension (HTN), diabetes mellitus (DM), and dyslipidemia based on the first date of uterine myomectomy in the UF group and the first visiting date for health screening in the non-UF group. There were 190,583 and 439,940 participants in the UF and control groups, respectively. Compared with those of the control group, the RRs of BBD, CIS, and BC were increased in the UF group. The hazard ratios (HRs) of BBD, CIS, and BC in the UF group were 1.335 (95% confidence interval (CI) 1.299-1.372), 1.796 (95% CI 1.542-2.092), and 1.3 (95% CI 1.198-1.41), respectively. When we analyzed the risk of BC according to age at inclusion, UFs group had the increased risk of BCs in all age groups in comparison with control group. Women with low SES (HR 0.514, 95% CI 0.36-0.734) and living in rural areas (HR 0.889, 95% CI 0.822-0.962) had a lower risk of BC. Our study showed that women with UFs had a higher risk of BBD, CIS, and BC than those without UFs. This result suggests that women with UFs should be more conscious of BC than those without UFs. Therefore, doctors should consider recommending regular breast self-exams, mammography, or ultrasound for the early detection of BC in women with UFs.

Project description:Using the nationwide health insurance claims database in Japan, we estimated total annual medical expenditures for fragility hip fracture across the population at 329.2 billion yen (2.99 billion US dollars). Long-term care expenditures were not included. Fragility hip fracture imposes a considerable health economic burden on society in Japan.PurposeFragility hip fracture imposes a substantial health economic burden on society globally. We aimed to estimate medical expenditures for fragility hip fracture using the nationwide health insurance claims database in Japan.MethodsWe included adults aged 60 and over without prior hip fracture who were admitted for fragility hip fracture (i.e., femoral neck or extracapsular) between October 2014 and October 2015 (13 months). Fragility hip fracture was identified through newly assigned disease codes for fracture and procedure codes associated with the fracture. As a proxy for medical expenditures per patient, incremental payments were calculated (i.e., the difference between the total payments 6 months before and after fragility hip fracture). The total payments included health insurance reimbursements and copayments for inpatient and outpatient services. Long-term care expenditures were not included in this study.ResultsWe identified 142,361 individuals (28,868 male and 113,493 female) with fragility hip fracture. Mean medical expenditures for fragility hip fracture per patient were 2,550,000 yen (¥) (23,180 US dollars [$]; ¥110 = $1) in male and ¥2,494,000 ($22,670) in female patients, respectively. Total annual medical expenditures for fragility hip fracture across the population were 329.2 billion yen (2.99 billion US dollars): 67.96 billion yen (620 million US dollars) in male and 261.24 billion yen (2.37 billion US dollars) in female patients, respectively.ConclusionThis is the first study to estimate medical expenditures for hip fracture using the nationwide health insurance claims database, which represents almost all health insurance claims in Japan. Fragility hip fracture inflicts a considerable health economic burden on society in Japan.

Project description:Background Invasive surgical procedures carry risk of harm to patients. In addition to avoidable harm, disparities between patient expectations and the outcome of a procedure may lead to patient injury claims. The follow-up of claims and compensation is an important entity for patient safety. The number of claims should be related to the surgical volume, so that a healthcare provider can benchmark with similar organizations and see if its trends are developing favourably or deteriorating. Our objective was to find out the claims and compensation rates due to surgery in an insurance-based system. Methods Data related to surgical claims and reference volume in the period 2011–2015 were collected from the claim register of the Finnish Patient Insurance Centre and benchmarking community register of Finnish operating departments. The data included age, gender, hospital, year of surgery, surgical code, and outcome of the claim. Results There were 8,901 claims related to the corresponding reference group of 1,470,435 surgical procedures. The claims rate was 0.61% and compensation rate was 0.22%. Trends for claims and compensation rates decreased over the study period. In high volume procedures, a low compensation rate was detected for excision of tonsils and adenoids, Caesarean section and extracapsular cataract operations using the phacoemulsification technique. A high compensation rate was detected for primary prosthetic replacement of the hip and knee joints and decompression of spinal cord and nerve roots. Unreasonable injury (death or permanent deterioration of health) was compensated in 2.4 per 100,000 procedures. Conclusions Register data research in a no-fault patient insurance system revealed a claims rate of 6 per 1,000 procedures and compensation rate of 2 per 1,000 procedures. A decreasing trend in both rates over the study period was detected. Different surgical procedures exhibit varying claims and compensation rates.
