CT Utilization, Imaging Costs And Radiation Dose Can Be Reduced By At Least 50%

It is unnecessary to scan based on a non-focused standard trauma CT , if the patient is transferred for care after already undergoing a focused based on the patient’s history and , a new study shows.

The study, conducted at the University of Pittsburgh Medical Center reviewed the records of 100 patients who were transferred from another facility. “The standard trauma CT protocol for all level 1 and 2 trauma patients transferred to our facility includes a CT examination of the head, cervical spine, thoracic spine, lumbar spine, chest, abdomen and pelvis,” said Dr. , a lead author in the study. “We found that these additional tests generated 463 negative . In seven patients, there were minor unexpected acute findings, such as non-displaced rib fractures. However, the findings did not change the treatment of any of these patients,” said Dr. Heller.

“In short, scanning patients according to the standard trauma protocol generated hundreds of CT examinations which did not impact the patient’s care,” said Dr. Heller. On average, we found that the standard trauma protocol generated approximately 5 CT examinations per patient that were either negative or not clinically significant,” he said.

“In our study, we estimate that CT utilization, imaging costs and radiation dose can be reduced by at least 50% if the standard imaging protocol is replaced by imaging dictated by the patient’s history and physical examination findings,” Dr. Heller said.
