Observational Study
The association between insurance status and diagnostic imaging for acute abdominal pain among emergency department patients in the United States, 2005-2014.
Introduction and objectives: Acute abdominal pain (AAP) is one of the most common complaints in the emergency department (ED). Rapid diagnosis is essential and is often achieved through imaging. Computed tomography (CT) is widely considered an exemplary test in the diagnosis of AAP in adult patients. ⋯ Additional findings are that black patients are 42% less likely to receive a CT scan than white patients. Conclusions and implications: Patients on Medicaid are significantly less likely to receive a CT when presenting to the ED with AAP. Differences in diagnostic care may correlate to inferior health outcomes in patients without private insurance.

Background: There is limited data on the real-life situation and outcomes of patients with metastatic triple-negative breast cancer (mTNBC) in Germany. The aim of this chart review was to describe the current treatment patterns, resource use and outcomes in this patient group. Methods: Retrospective data collection in 30 gyneco-oncological sites (hospitals and office-based) across Germany between January and April 2017. ⋯ For first-, second- and third-line therapy, median overall survival was 19.1/10.8/14.6 months, and median progression-free survival was 7.7/2.5/5.6 months. Conclusion: In clinical routine, a wide variety of treatment approaches is applied, while outcomes in terms of survival are poor. New treatment options are needed for this challenging tumor type.

Objectives: This report characterizes flupirtine prescribing patterns before and after the implementation of risk minimization measures (RMM) in Germany as a complementary analysis to support previous study findings. Methods: A retrospective analysis was conducted using a patient-level longitudinal prescription database (IMS LRx) in Germany. The study population included patients who were prescribed flupirtine-containing products. ⋯ Concomitant prescriptions of drugs with known potential hepatotoxic effects were recorded in 36.6% and 34.2% of flupirtine prescriptions during the pre- and post-implementation periods, respectively. Conclusions: While physicians generally restricted flupirtine prescriptions to the short-term treatment duration recommended in the labeling, the other labeling recommendations were not as stringently adopted. Findings of this investigation support a previous study conducted in an electronic medical record database.

Purpose: The purpose of this study is to determine racial and ethnic disparities with the adherence to inhaled corticosteroids (ICSs) in adults with persistent asthma, and their association with healthcare expenditures. Methods: A retrospective, cross-sectional study using the Medical Expenditure Panel Survey (MEPS) 2013-2014 data included patients ≥18 years with persistent asthma. Median medication possession ratio (MPR) was used to dichotomize adherence levels. ⋯ African-Americans had slightly higher total expenditure compared to whites; however, other minorities had significantly lower health expenditures compared to whites (p = .01). Non-Hispanics spent significantly less on healthcare compared to Hispanics (p = .04). Conclusions: Valuable insight into the economic cost of the disparities as they relate to persistent asthma provides further evidence of possible ethnic inequities that warrant addressing.

Objective: Describe the development of a claims-based classifier utilizing machine learning to identify patients with probable Lennox-Gastaut syndrome (LGS) from six state Medicaid programs. Methods: Patients were included if they had ≥2 medical claims ≥30 days apart for specified or unspecified epilepsy, excluding those with ≥1 claim for petit mal status. The LGS classifier utilized a random forest algorithm, a compilation of thousands of binary decision trees in which machine-generated predictor variables split the data set into branches that predict the presence or absence of LGS. ⋯ The random forest methodology outperformed logistic regression and single tree methodology. Most of the important LGS predictor characteristics identified by the classifier were statistically significantly associated with LGS status (p < .05). Conclusions: The claims-based LGS classifier showed high sensitivity and specificity, outperformed single tree and logistic regression methodologies and identified a prevalence of probable LGS that was similar to previously published estimates.
