Although nonradiologist physicians have contributed to the widespread use of point-of-care ultrasound, radiologists remain the primary users, according to a new study published in the November issue of the Journal of the American College of Radiology.
Researchers at Thomas Jefferson University looked at Medicare Part B databases from 2004 to 2009 to determine the rate of utilization of noncardiac ultrasound by radiologists and other specialists. The team found a 21% increase in the overall utilization rate of noncardiac ultrasound during the time frame.
In 2009, point-of-care ultrasound conducted by nonradiologists was 41% of all studies, while point-of-care ultrasound conducted by radiologists was 55% (JACR, November 2011, Vol. 8:11, pp. 772-775).
Although radiologists are still majority users of noncardiac ultrasound, the progressive miniaturization of the technology and ensuing drop in cost may change that, according to lead author Dr. David C. Levin. Utilization trends for this technology will require further watching and additional research in the coming years, he added.
