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

Relationship Between Hospital Compliance With Medicare’s Price Transparency Rule, Proposed Cash Prices, and Consumer Ratings for MRI Spine

Between September and October 2021, the researchers manually searched the websites of all hospitals listed in the Medicare Hospital Compare Quality of Care database with publicly available OP-8 scores. OP-8 is a CMS imaging quality metric showing the annual percentage of patients undergoing lumbar spine MRI for back pain in an outpatient facility and was used to identify hospitals offering lumbar spine MRI. Hospital compliance with the CMS price transparency mandate was determined by a multivariable model. Read the study for full details. Full Article

Secondary Interpretations of Diagnostic Imaging Examinations: Patient Liabilities and Out-of-Pocket Costs

Secondary interpretations of diagnostic imaging examinations are increasingly performed to improve care for complex patients. This study sought to determine associated patient-billed liabilities and out-of-pocket payments and to identify patient and imaging study characteristics that correlate with higher patient bills and out-of-pocket payments.

Radiologist Characteristics Associated with Interpretive Performance of Screening Mammography: A National Mammography Database (NMD) Study

Across radiologists nationally, geography, breast subspecialization, and performance of diagnostic mammography are associated with better screening mammography performance; performance of breast US is associated with lower performance. Factors affecting radiologists’ performance in screening mammography interpretation remain poorly understood. The purpose of this study it to identify radiologists characteristics that affect screening mammography interpretation performance. Full Article
