A new study from the HPI found that both practice-level and radiologist-level IR specialization are associated with increasing procedural complexity, and nurse practitioners and physician assistants, through the provision of evaluation and management services, contributed to increased procedural complexity to the interventional radiologists they support. This practice-level analysis was published in JACR. Read More

A new study from the Neiman Institute found that the odds of imaging following an office visit were 188% higher when ordering clinician self-interpreted the imaging they ordered versus referring interpretation to a radiologist. Practices that routinely referred imaging to a radiologist also demonstrated lower imaging use following office visits. The study, based on 24.2 million Medicare office visits, was published in JACR.

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 time between an imaging scan and its interpretation for office/hospital outpatient imaging increased 27% between 2023 and 2024. The study, based on 2.9 million office/hospital outpatient Medicare imaging studies, published in JACR, was an update to previous HPI study of turnaround times through 2023. 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

Radiologists performing no interventional radiology-related work increased from one-third in 2008 to one-half in 2023. These findings, based on a national Medicare analysis of 46,533 radiologists covering 476,688 radiologist years from 2008 to 2023 period, were published in the JVIR by the HPI in collaboration with IR experts.
