The primary objective of this study was to describe surgical treatment patterns among women with newly diagnosed uterine fibroids (UF). A secondary objective was to estimate the medical costs associated with other common surgical interventions for UF. Claims-based commercial and Medicare data (2011-2016) were used to identify women aged ≥30 years with continuous enrollment for at least 12 months before and after a new diagnosis of UF. Receipt of a surgical or radiologic procedure (hysterectomy, myomectomy, endometrial ablation, uterine artery embolization, and curettage) was the primary outcome. Health care resource utilization and costs were calculated for women with at least 12 months of continuous enrollment following a UF surgical procedure. Among women who met selection criteria, 31.7% of patients underwent a surgical procedure; 20.9% of these underwent hysterectomy. An increase was observed over time in the percentage of women undergoing outpatient hysterectomy (from 27.0% to 40.2%) and hysteroscopic myomectomy (from 8.0% to 11.5%). The cost analysis revealed that total health care costs for hysteroscopic myomectomy ($17,324) were significantly lower (P < 0.001) than those for women who underwent inpatient hysterectomy ($24,027) and those for women undergoing the 3 comparison procedures. Hysterectomy was the most common surgical intervention. Patients undergoing inpatient hysterectomy had the highest health care costs. Although less expensive, minimally invasive approaches are becoming more common; they are performed infrequently in patients with newly diagnosed UF. The results of this study may be useful in guiding decisions regarding the most appropriate and cost-effective surgical treatment for UF.

Over the course of the last three decades it has become apparent that the majority of cases of acute myeloid leukemia (AML) are characterized by at least one of a variety of recurrent chromosomal abnormalities. Whilst in many instances it remains uncertain as to which abnormalities represent primary events in the pathogenesis of AML, those which provide critical second hits that are required for progression to full blown leukemia or those that are merely markers of the leukemic process, it is nevertheless clear that diagnostic karyotype is a key determinant of outcome in this disease. Indeed there is mounting evidence to support the notion that cytogenetic analysis can serve to identify biologically distinct subsets of AML that demand tailored therapeutic approaches. This underpins the trend towards more widespread adoption of routine cytogenetic and molecular analysis in the characterization of patients with a diagnosis of acute leukemia. A key challenge for the future is to use this information to achieve greater consensus in risk group assignment of AML which will provide a more reliable framework for determining the most appropriate treatment approach for individual patients with this disease.

PurposePatients with severe asthma are eligible for asthma-specific biologics as add-on therapies, such as mepolizumab and omalizumab, when optimized controller therapies are unable to control their symptoms. However, few real-world data are available to describe the characteristics and associated economic burden of patients considered to be candidates for mepolizumab or omalizumab therapy.MethodsThis retrospective cohort study investigated patients with asthma (≥12 years of age) identified at the time of first mepolizumab or omalizumab administration (index date) in the MarketScan™ Commercial Database. Data were collected during the 12-month period before the index date (baseline period) for two mutually exclusive patient groups (patients prescribed mepolizumab and omalizumab, respectively). Baseline demographics, history of exacerbations, healthcare resource utilization (HCRU), and medical costs were investigated.ResultsIn total, 413 and 1,834 patients who had been prescribed mepolizumab or omalizumab, respectively, were identified. During the baseline period, patients prescribed mepolizumab experienced more exacerbations (81.4% vs 57.5%, P<0.001), had higher asthma-related HCRU for outpatient services (all P<0.01), and had higher total asthma-related healthcare costs (US$11,000 vs US$7,400, P<0.001) compared with patients prescribed omalizumab. Allergic rhinitis, atopic dermatitis, and chronic idiopathic urticaria were more common among patients prescribed omalizumab vs mepolizumab. In contrast, sinusitis, nasal polyps, and comorbid COPD were more common among patients prescribed mepolizumab vs omalizumab. Prescriptions of fixed-dose inhaled corticosteroids (ICSs) with long-acting β2-agonists (LABAs) and ICS/LABA/long-acting muscarinic antagonist triple therapy during the baseline period were higher among patients prescribed mepolizumab vs omalizumab (80.4% vs 56.8% and 27.1% vs 14.4%, respectively, both P<0.001).ConclusionIn the 12 months prior to initiation of asthma-specific biologics, patients prescribed mepolizumab had a different prevalence of certain comorbidities, higher disease burden, higher HCRU, and higher healthcare costs compared with patients prescribed omalizumab.

The relationship between Alzheimer's disease (AD) treatment patterns and healthcare costs is unknown. Administrative claims data from the MarketScan Commercial and Medicare databases covering 2010 through 2016 were used to identify the comorbidities, treatment patterns, and healthcare costs in the three years prior to and one year post medical diagnosis of AD in 21,448 patients with no treatment and 57,970 patients with treatment.

Background Most patients with epidermal growth factor receptor mutation-positive (EGFRm) non-small-cell lung cancer (NSCLC) acquire resistance to first-line (1L) first-or second-generation (1G/2G) EGFR-TKIs; therefore, it is important to optimize 1L treatment to improve patient outcomes. Objective To retrospectively examine treatment patterns in locally advanced/metastatic NSCLC using MarketScan ® Commercial and Medicare Supplemental Databases (all US census regions). Patients and methods Adults with a lung cancer diagnosis code between 1 January 2015-31 March 2018 were analyzed from diagnosis (index) through a variable-length follow-up. Patients had ≥ 1 pharmacy claim for 1G/2G EGFR-TKIs on or within 60 days post-index. Data were stratified by presence or absence of central nervous system (CNS) metastases (30 days pre-index through study end). Results 578 patients were included (median age 63 years, 64% female). Median follow-up was 13.5 months. The most frequently prescribed 1L EGFR-TKI was erlotinib (414/578, 72%). Median time to 1L treatment discontinuation was 8.2 (95% confidence interval (CI) 6.9, 9.0) months in patients diagnosed with CNS metastases at any time, and 7.7 (95% CI 6.9, 8.9) months in patients without CNS metastases. 270/578 patients (47%) discontinued 1L EGFR-TKIs; 209/270 (77%) initiated second-line (2L) therapy, most frequently osimertinib (96/209, 46%). Conclusions In an analysis of US claims data, nearly half of patients discontinued 1L EGFR-TKIs, and 46% who initiated 2L received osimertinib. As nearly a quarter of patients who discontinued 1L EGFR-TKIs did not receive 2L treatment, this study highlights the need for optimal 1L treatment in EGFRm locally advanced/metastatic NSCLC.
