Abstract
INTRODUCTION: Whole body computed tomography has become standard practice in many centres in the management of severely injured trauma patients, however, the evidence for it's diagnostic accuracy is limited. AIM: To assess the sensitivity of whole body CT in major trauma. METHOD: Retrospective review of all patients with injury severity score (ISS) > 15 presenting with blunt trauma to a UK Major Trauma Centre between May 2012 and April 2014. Injuries were classified as per ISS score-1 = head and neck 2 = face 3 = chest 4 = abdomen. The authors reviewed patient's electronic charts, radiological results; interventional procedure records, discharge letters and outpatient follow up documentation and referenced this with Trauma Audit and Research Network data. RESULTS: 407 patients with ISS > 15 presented to the Trauma centre during May 2012 and April 2014. Of these, 337 (82.8%) had a whole body CT scan. 246 pts were male, 91 were female. 74 (21.9%) were due to a fall from > 2 m, 41 (12.2%) due to a fall from < 2 m, 208 (61.7%) were due to motor vehicle crashes, 1 (0.3%) due to a blast injury, 5 (1.5%) due to blows, and 8 (2.4%) due to crush injuries. Sensitivity for Region 1 was 0.98, Region 2 = 0.98, Region 3 = 0.98 and Region 4 was 0.95. Overall sensitivity was 0.98. 15 injuries (2.4%) were not identified on initial CT (false -ve). These injuries were: colonic perforation = 1, splenic contusion = 1, pneumothorax = 1, liver laceration = 1, intracranial haemorrhage = 1, cerebral contusions = 1, spinal injuries = 7, canal haemorrhage = 1, maxilla fracture = 1. CONCLUSION: These results show that whole body CT in trauma has a high sensitivity and a low rate of missed injuries (2.4%). However, our study only evaluated a subgroup of patients with ISS > 15 and further work is required to assess the use of this investigation for all major trauma patients.
