Recent trends in radiology imaging portend a dramatic and rapid reduction in this segment of a hospital’s business plan. Even before capitated (or global) payments have come into full play, there has been a large reduction in the number of some types of imaging studies in hospitals.

Our Chief of Radiology summarizes our experience — common to other hospitals as well — and provides some of the reasons.

The biggest hit has been in CT, the modality we are most dependent on for revenue. We are about 10% down in CT cases from last year, due to a combination of patient and physician fears about radiation exposure, more prudent ordering of studies by physicians, leakage out of the medical center, and the introduction of physician incentive programs (to minimize the amount of imaging) by some insurers.

Also, and very surprising, we have not seen an upswing in ultrasound or MRI to match the CT volume drop. We have, however, seen an increase in the number of patients arriving with their scans on CD ROMS having been imaged at other lower priced vendors. We don’t bill for these interpretations even though we are frequently asked to reinterpret the studies for our clinicians, and BIDMC is paying to store these images on our PACS systems.

By the way, this occurred while our overall patient volume increased during the same period.

The result of these trends will be to reduce the number of radiologists working in hospitals, and there will also probably result in a reduction of salaries for this physician specialty.

Paul recently became the focus of much media attention when he decided to publish infection rates at his hospital, despite the fact that under Massachusetts law he is not yet required to do so. For the past three years he has blogged about his experiences in an online journal, Running a Hospital, one of the few blogs we know of maintained by a senior hospital executive.
