In brief
South African trauma center study reveals potential CT overuse in pediatric trauma patients, with 50% of scans showing normal findings and low intervention rates (7% for head CT, 10% for abdominal CT). The pattern mirrors historical overutilization seen in high-income countries, suggesting middle-income settings may benefit from evidence-based imaging guidelines to reduce unnecessary radiation exposure.

Abstract
Purpose
Sustained efforts in high-income countries have decreased the rate of unnecessary computed tomography (CT) among children, aiming to minimize radiation exposure. There are little data regarding CT use for pediatric trauma in low- and middle-income countries. We aimed to assess the pattern and utility of CT performed during evaluation of trauma patients presenting to a middle-income country (MIC) trauma center.
Methods
We reviewed pediatric (age<18) trauma admissions at a single tertiary referral center in South Africa. Patient demographics, injury details, surgical intervention(s), and mortality were abstracted from the medical record. CT indications, results, and necessity were determined by review.
Results
Of 1,630 children admitted to the trauma center, 826 (51%) had CT imaging. Children undergoing imaging were younger (median age 11 [IQR: 6, 16] vs 13 [IQR: 7, 17]) and had higher median ISS [9 [IQR: 4, 13] vs 4 [2, 9]) compared to those without imaging (both p<0.001). Overall, 1,224 scans were performed with normal findings in 609 (50%). A median of 1 scan was performed per patient (range: 1–5). The most common location was CT head (n = 695, 57%). Among patients with positive findings on CT head (n = 443), 31 (7%) underwent either intracranial pressure monitoring or surgery. CT of the cervical spine had positive findings in 12 (7%) with no patients undergoing spine surgery. Of 173 patients with abdominal CT imaging, 83 (48%) had abnormal findings and 18 (10%) required operative exploration. Thirteen (16%) patients with abnormal findings on abdominal CT had exploratory laparotomy. Of 111 children undergoing whole body CT, 8 (7%) underwent thoracic and/or abdominal operations.
Conclusion
Use of CT during evaluation of pediatric trauma is common in an MIC center. A high rate of normal findings and low rates of intervention following head, cervical spine, and abdominal CT suggest potential overuse of this resource.
