Abstract.



Purpose: Radiologist medical school pathways have received little attention in recent workforce investigations. With osteopathic enrollment increasing, we assessed the osteopathic versus allopathic composition of the radiologist workforce.

Methods: Linking separate Medicare Doctors and Clinicians Initiative databases and Physician and Other Supplier Files from 2014 through 2019, we assessed (descriptively and using multivariate panel logistic regression modeling) individual and practice characteristics of radiologists who self-reported medical degrees.

Results: Between 2014 and 2019, as the number of osteopathic radiologists increased 46.0% (4.7% to 6.0% of total radiologist workforce), the number of allopathic radiologists increased 12.1% (representing a relative workforce decrease from 95.3% to 94.0%). For each year since completing training, practicing radiologists were 3.7% less likely to have osteopathic (versus allopathic) degrees (odds ratio [OR] = 0.96 per year, P < .01). Osteopathic radiologists were less likely to work in urban (versus rural) areas (OR = 0.95), and compared with the Midwest, less likely to work in the Northeast (OR = 0.96), South (OR = 0.95), and West (OR = 0.94) (all P < .01). Except for cardiothoracic imaging (OR = 0.78, P = .24), osteopathic radiologists were more likely than allopathic radiologists to practice as general (rather than subspecialty) radiologists (range OR = 0.37 for nuclear medicine to OR = 0.65 for neuroradiology, all P < .01).

Conclusions: Osteopathic physicians represent a fast-growing earlier-career component of the radiologist workforce. Compared with allopathic radiologists, they more frequently practice as generalist radiologists, in rural areas, and in the Midwest. Given recent calls for greater general and rural radiology coverage, increasing osteopathic representation in the national radiologist workforce could improve patient access.
