Longitudinal Analysis of Neurodiagnostic Testing Utilization in Emergency Department Patients Presenting with Seizures or Epilepsy

The aim of this study was to assess neurodiagnostic testing utilization in US emergency department (ED) patients presenting with seizures or epilepsy between 2006 and 2014.

Increasing and Disparate use of Neuroimaging for Adults and Children with Non‐Traumatic Headaches in the US Emergency Departments: Opportunities for Improvement

Optimization of neuroimaging practices for headache is considered a national priority; however, nationwide patterns and predictors of neuroimaging use for headache in the US emergency departments (EDs) are unknown. The objective of this study is to analyze temporal neuroimaging utilization trends for adults and children with non-traumatic headache in the US EDs and identify factors predictive of neuroimaging use in this patient population.

Disparities in the Use of Emergency Department Advanced Imaging in Medicare Beneficiaries

The purpose of this study was to assess potential disparities in the utilization of advanced imaging during emergency department (ED) visits. This retrospective study was conducting using 5% Research Identifiable Files. All CT and MRI (together defined as “advanced imaging”) examinations associated with ED visits in 2015 were identified for continuously enrolled Medicare beneficiaries. Among Medicare beneficiaries receiving care in U.S. EDs, significant disparities exist in advanced imaging utilization. Although imaging appropriateness was not investigated, these findings suggest inequity. Further research is necessary to understand why consistent health benefits do not translate into consistent imaging access among risk-adjusted ED patients. Full Article

The Neiman Institute COVID-19 Studies

To understand the impact of COVID-19 on radiology in a variety of care-delivery settings, the Harvey L. Neiman Health Policy Institute (HPI®) initiated a series of studies from an integrated healthcare system in New York and community radiology practices, and analyzed data from a national survey of radiology practices.

Trends in Radiology Physician Workforce Mobility

Using two separate publicly available Medicare datasets, the researchers studied the frequency and characteristics of radiologist-practice separation between 2014 – 2018. View Infographic

Evolving Use of fMRI in Medicare Beneficiaries

Using the Medicare Physician-Supplier Procedure Summary Master File, we evaluated the evolving use of fMRI in Medicare fee-for-service beneficiaries from 2007 through 2017. Annual use rates (per 1,000,000 enrollees) increased from 17.7 to 32.8 through 2014 and have remained static since. Radiologists have remained the dominant specialty group from 2007 to 2017 (86.4% and 88.6% of all services, respectively), and the outpatient setting has remained the dominant place of service (65.4% and 65.4%, respectively).

National Trends in Oncologic Diagnostic Imaging

This study characterize national trends in oncologic imaging (OI) utilization. This retrospective cross-sectional study used 2004 and 2016 CMS 5% Carrier Claims Research Identifiable Files. Radiologist-performed, primary noninvasive diagnostic imaging examinations were identified from billed Current Procedural Terminology codes; CT, MRI, and PET/CT examinations were categorized as “advanced” imaging. OI examinations were identified from imaging claims’ primary International Classification of Diseases-9 and International Classification of Diseases-10 codes. Imaging services were stratified by academic practice status and place of service. State-level correlations of oncologic advanced imaging utilization (examinations per 1,000 beneficiaries) with cancer prevalence and radiologist supply were assessed by Spearman correlation coefficient.OI usage varied between practice settings. Although the percentage of advanced OI done in academic settings nearly doubled from 2004 to 2016, the majority remained in nonacademic practices. Full Article
