Radiologists are taking longer to interpret medical images than they did 10 years ago … and it’s a problem that appears to be getting worse. New data from the ACR’s Neiman HPI group, published in JACR, show that report turnaround times rose 27% between 2023 and 2024.
Report turnaround time (commonly referred to as TAT) is a closely watched barometer of radiologist productivity, and longer TAT could indicate radiologists are struggling to keep up with growing imaging volumes.
- Another Neiman HPI study on TAT released earlier this year discovered a “hockey stick” effect, with turnaround times jumping sharply starting in 2022.
But that study only tracked TAT through 2023. Meanwhile, anecdotal reports have surfaced of a “rapid increase” in turnaround times in late 2024.
- So the updated research adds more recent data, analyzing newly available Medicare fee-for-service claims from 2024.
Researchers analyzed data from 2.9M office and hospital outpatient claims from 2014 to 2024, finding that TAT…
- Grew just 14% in seven years from 2014 to 2021 (0.091 to 0.104 days).
- But then rose at double-digit annual rates in 2023 (60%) and 2024 (27%).
- Reached 0.251 days by the end of 2024, a 177% increase over 10 years.
- Increased at different rates by modality over the 10-year period, including CT (381%), MRI (278%), ultrasound (267%), and X-ray (126%).
Why did TAT growth decelerate in 2024 over the year before? The Neiman HPI authors weren’t sure, but they said practice leaders may have taken steps to meet higher demand, like moonlighting and reactivating retired staff.
- But these aren’t long-term measures that can meet the mismatch between supply and demand, suggesting instead that “the radiology workforce may be operating at or near maximum capacity.”
The Takeaway
The new data on slower radiology report turnaround times confirm fears that radiologists are struggling under rising imaging volumes and a stagnant workforce. While slower TAT growth in 2024 is a bit of a silver lining, it does little to hide the growing storm clouds on the horizon.
