Abstract

BACKGROUND

We evaluated the accuracy of surgery residents in interpreting computed axial tomography (CT) scans of trauma patients as compared with attending radiologists.

METHODS

Residents listed injuries they identified on initial CT scans of trauma patients in a time-stamped computerized system before the official report becoming available. Head, chest, and abdomen/pelvis CT scans were included. We compared the accuracy of these reads with final radiology reports.

RESULTS

There were 84 injuries in 31 patients. Residents correctly identified 25 of 26 (96%) injuries to the head, 28 of 42 (67%) chest injuries, and 15 of 16 (94%) injuries to the abdomen and pelvis. The accuracy of resident reads of chest CT scans was lower (P = .035) than for other body areas. Radiologists' identified 23 of 26 (89%) head injuries, 38 of 42 (90%) chest injuries, and 14 of 16 (88%) injuries in the abdomen and pelvis CT scans. None of the missed injuries were life threatening or required immediate attention.

CONCLUSIONS

Surgical residents accurately identify acute injuries on the CT scans of trauma victims.

摘要

背景

我们评估了外科住院医师与放射科主治医生相比，解读创伤患者计算机断层扫描（CT）图像的准确性。

方法

住院医师在官方报告发布前，在一个带时间戳的计算机系统中列出他们在创伤患者初始CT扫描中识别出的损伤。纳入头部、胸部和腹部/骨盆的CT扫描。我们将这些解读的准确性与最终的放射学报告进行比较。

结果

31例患者共有84处损伤。住院医师正确识别出头部26处损伤中的25处（96%）、胸部42处损伤中的28处（67%）以及腹部和骨盆16处损伤中的15处（94%）。住院医师对胸部CT扫描解读的准确性低于其他身体部位（P = 0.035）。放射科医生在头部CT扫描中识别出26处损伤中的23处（89%）、胸部42处损伤中的38处（90%）以及腹部和骨盆CT扫描中16处损伤中的14处（88%）。所有漏诊的损伤均无生命危险，也无需立即处理。
