The tendency to do unnecessary CT scans raises healthcare costs, also leads to excessive radiation exposure
It is almost a norm that a patient brought to the emergency has to undergo a CT scan to check for fractures or haemorrhage.
Only, a lot of it may be unnecessary; it raises nor just treatment costs but also leads to needless radiation exposure, according to a study to be presented at the American Roentgen Ray Society (ARRS) 2018 Annual Meeting, set for April 22-27 in Washington, DC.
Of 492 cases reviewed, 260 (52.8%) and 376 (76.4%) of the CT examinations were not indicated
The study, to be presented by Michaela Cellina, of the Radiology Department of Fatebenefratelli-Sacco Hospital in Milan, Italy, evaluated head CT scans for minor head injury (MHI) in patients aged 18-45 who came to the hospital’s emergency department between January 1 and June 30, 2016.
For each CT scan, researchers determined whether the CT referral met the criteria indicated by the National Institute for Health and Care Excellence (NICE) and the Canadian CT Head Rule (CCHR).
Of 492 cases reviewed, 260 (52.8%) and 376 (76.4%) of the CT examinations were not indicated according to the NICE and CCHR, respectively.
Motor vehicle accidents were associated with a higher rate of non-indicated CT examinations for both NICE and CCHR, and two-wheel vehicle driver accidents were associated with a higher rate of appropriated CT exams for both NICE and CCHR. Only 15 of the 260 CT examinations were positive for brain hemorrhage, subarachnoid hemorrhage, or skull fracture.
With educational activities representing the entire spectrum of radiology, ARRS will host leading radiologists from around the world at the ARRS 2018 Annual Meeting, April 22-27, at the Marriott Wardman Park Hotel in Washington, DC.
