The Harvey L. Neiman Health Policy Institute® studies the value and role of radiology in evolving health care delivery and payment systems, including quality based approaches to care and the impact of medical imaging on overall health care costs. Neiman Institute research provides a foundation for evidence-based imaging policy to improve patient care and bolster efficient, effective use of health care resources.

Access & Quality

Predicted Cost Savings Achieved by the Radiology Support, Communication and Alignment Network from Reducing Medical Imaging Overutilization in the Medicare Population

The Radiology Support, Communication and Alignment Network (R-SCAN) is a quality improvement program through which patients, referring clinicians, and radiologists collaborate to improve imaging appropriateness based on Choosing Wisely recommendations and ACR Appropriateness Criteria. R-SCAN was shown previously to increase the odds of obtaining an appropriate, higher patient or diagnostic value, imaging study. In the current study, the researchers aimed to estimate the potential imaging cost savings associated with R-SCAN use for the Medicare population. Full Article

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).
