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.

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

Characteristics of Coronavirus Disease 2019 (COVID-19) Community Practice Declines in Noninvasive Diagnostic Imaging Professional Work

The operational and financial impact of the widespread coronavirus disease 2019 (COVID-19) curtailment of imaging services on radiology practices is unknown. We aimed to characterize recent COVID-19-related community practice noninvasive diagnostic imaging professional work declines. The authors used imaging metadata from nine community radiology practices across the United States between January 2019 and May 2020, and mapped work relative value unit (wRVU)-weighted stand-alone noninvasive diagnostic imaging service codes to both modality and body region.
