A new HPI study found that office-based imaging studies were more likely to be repeated within 90 days when the initial study was interpreted by a non-physician practitioner than when interpreted by a radiologist. The study, published in the JACR, was based on 1.3 million Medicare imaging claims between 2013 and 2022. Read More

A new HPI study published in JACR reveals a concerning decline in the number of U.S. radiologists dedicating most of their clinical effort to pediatric imaging. Using a large, national private payor claims database including approximately 414M unique covered lives, researchers found that the pediatric radiology workforce shrank between 2016 and 2023, even as demand for imaging services grew.

A new JACR study found that during the COVID-19 pandemic, telemedicine visits led to significantly lower use of diagnostic imaging compared to similar in-person visits, highlighting telemedicine’s potential effect on follow-up medical care. Read More

A new study published in CHEST finds that Medicare beneficiaries who participated in a shared decision-making visit with their healthcare provider prior to their initial lung cancer screening were significantly more likely to adhere to recommended annual follow-up screenings over a four-year period.

A new Harvey L. Neiman Health Policy Institute study found evidence that a new diagnosis of sarcopenia, a potentially reversible disease with low muscle mass and strength, often coincides with an abdominal CT study. Increasing opportunistic evaluation of abdominal CT scans could facilitate diagnosis of sarcopenia and ultimately improve patient care. Read More

A new Neiman Health Policy Institute study found that 43.6% of office-based imaging studies were interpreted by the ordering provider, with 58.5% interpreted within the ordering provider’s practice. Self-interpretation rates varied by specialty and imaging modality. Published in the AJR, the study analyzed over 1.6 million Medicare imaging claims from 2022. Read More

A new study from the Harvey L. Neiman Health Policy Institute found that unnecessary imaging studies in Original Medicare are associated with up to 129 kT of CO2 emissions – the same as would be produced from powering a town of over 70,000 people for a year. The research, published in JACR, demonstrates the opportunity for the field of radiology to meaningfully reduce its environmental footprint. Read More

A new multi-institute study demonstrates the potential prevention and economic benefits from the opportunistic use of CT, defined as screening performed using CT images that were collected for a different purpose. The study showed that using CT imaging for osteoporosis could increase the screening rate in the Medicare population by 113% without requiring any additional imaging. Read More

New Harvey L. Neiman Health Policy Institute research found significant differences in performance across radiologists in the CMS Merit-Based Incentive Payment System (MIPS). The researchers examined a broad range of radiologist and practice characteristics and identified the set of factors that predicted whether a radiologist would score exceptionally, and thus receive the highest payment bonus, Read More
