Price Transparency: Progress or Problems?

Consumer price listings may ultimately give consumers less of what they really want — high quality care. While transparent pricing is theoretically ideal for allowing patients to make informed decisions, the complexity of healthcare in the U.S. makes a truly transparent system a challenge and there are numerous caveats.

Radiology Practices Employing Nurse Practitioners and Physician Assistants: Characteristics and Trends From 2017 Through 2019

The number and roles of US nonphysician practitioners (NPPs) have expanded considerably, but little is known about their use by radiology practices. The authors assessed characteristics and trends of radiology practices employing Medicare-recognized NPPs. Full Article

Developmental Hip Dysplasia and Hip Ultrasound Frequency in a Large American Payer Database

Developmental dysplasia of the hip (DDH) is an important contributor to musculoskeletal morbidity, but effective strategies to screen for DDH remain controversial. The current utilization of hip ultrasound (US) screening for DDH in the United States is not defined. This study utilized Optum's de-identified Clinformatics® Data Mart, a large commercial and Medicare Advantage claims database. Full Article

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.
