A new HPI study reveals a substantial decline in DXA testing among Medicare beneficiaries that was greatest in certain underserved groups. The findings raise concerns about missed opportunities to diagnose osteoporosis and prevent fractures and associated costs. The study analyzed nearly two decades of Medicare claims data from more than 5 million beneficiaries and found that use of DXA fell by 35% over the study period. Read More

A new study from the Neiman Institute found that the persistent declines in Medicare physician reimbursement are associated with widening disparities in access to care, with patients in rural communities, low-income areas, and disadvantaged neighborhoods falling further behind their more urban, affluent, and advantaged counterparts. The study, based on 4.7 million unique patients over the 2005-2023 period, was published in INQUIRY: The Journal of Health Care Organization, Provision, and Financing. Read More

A new study from the Neiman Institute found that the introduction of PET-based Gallium-68 DOTATATE/DOTATOC radiotracers for imaging neuroendocrine tumors created substantial differences in patient access during its first four years of use. Compared with the older imaging agent, Indium-111 pentetreotide (Octreoscan™), patients in small town-rural areas traveled 134.9 additional miles on average to access Gallium-68 DOTATATE/DOTATOC. The study, published in JACR, analyzed 3,365 claims for neuroendocrine tumor radiotracers. Read More

A new study from the HPI found that the time between an imaging scan and its interpretation for office/hospital outpatient imaging increased 113% between 2014 and 2023, with most of this increase occurring in 2022 and 2023. The study, published in the JACR, was based on claims for 2.6 million office/hospital outpatient imaging studies. Read More

A new study from HPI found that attrition (i.e., exit) from the radiology workforce increased for all subspecialties, but with varying magnitude. The study, published in AJR, was based on all Medicare radiologists who submitted claims between 2014 and 2022 and covered 159,490 radiologist-year observations for 29,770 radiologists practicing as subspecialists.
