New Study Evaluates Transcatheter Dialysis Conduit Procedures Over 15 Years

A new research study by Harvey L. Neiman Health Policy Institute found that utilization of invasive procedures on hemodialysis conduits—artificially constructed shuts used by many individuals who require dialysis—increased markedly from 2001 through 2015 for nephrologists and declined for radiologists. The study is published online in the Journal of Vascular and Interventional Radiology (JVIR). Read More

The Decline of State-Level IVC Filter Utilization

After a period of prior growth, national inferior vena cava (IVC) filter utilization in the Medicare population has markedly declined over the last decade according to a prior Neiman Institute study published in 2018. This new study, published online in the American Journal of Roentgenology, assesses state level IVC filter utilization and expands the population set to include both the Medicare and the privately insured population.

Bundle Payment Model Analysis of Emerging Breast Cancer Screening

Bundled payments have been touted as mechanisms to optimize quality and costs. A prior feasibility study evaluating bundled payments for screening mammography episodes predated widespread adoption of digital breast tomosynthesis (DBT). A new study, published online in the Journal of the American College of Radiology (JACR), explores an episodic bundled payment model for breast cancer screening that reflects the emerging widespread adoption of DBT.

The Decline of Radiology Trainee Exposure to Invasive Procedures

As interventional radiology (IR) evolves as a distinct specialty from diagnostic radiology (DR), the central and ongoing role of diagnostic radiologists in performing certain invasive radiological procedures could have important patient access implications. This study, published online in the JACR, characterizes longitudinal changes in radiology trainees’ exposure to invasive image-guided procedures. Read More
