CT SCANNING WITH POLYTRAUMA PROTOCOL: IS THE PATIENT OVER-SCANNED?

Abstract

Trauma is the leading cause of death in individuals under 45 years old. CT scan with polytrauma

protocol plays a crucial role in the rapid assessment of trauma patients. However, its routine us-

age may result in unnecessary imaging, increased radiation exposure and higher healthcare costs.

This study aimed to evaluate the overuse of CT scans performed with polytrauma protocol

based on clinician’s request.

Materials and Methods: A retrospective review of 138 trauma patients referred to polytrauma

CT scans between March and May 2025, that was conducted using PACS data from two institu-

tions. The average patients’ age was 46.3 years (range: 4–89 years), with 79% being male.

Inclusion criteria were trauma patients referred to CT with polytrauma protocol. The number of

injured body parts was compared to the number of parts scanned to assess scan necessity.

Results: Out of 138 patients 49 (35.5%) had positive CT findings. Out of 49 patients 32 (65.3%)

met polytrauma criteria. Only 4 patients (8.2%) had indication for CT scan with polytrauma

protocol. 45 (91.8%) of the patients were over-scanned. 75% excess scanning had 17 patients

(37.7%), 50% over-scanning had 20 patients (44.4%), and 25% over-scanning was done in 7

patients (15.5%). The most unnecessary examinations were performed to neck in 85.7% and

abdomen in 46.6%, in comparison to chest (33.3%).

Conclusion: A significant number of patients underwent unnecessary CT scanning, particu-

larly involving the neck and abdomen. These findings underscore the importance of clinical

guidelines to reduce over-scanning, minimize radiation, lower costs and improve trauma care

efficiency.
