Surgical residents routinely interpret radiographic studies during the evaluation of trauma patients, which directs further evaluation and invasive procedures. Official interpretations--"post-reading"--of radiographs by radiologists may be delayed by hours or even days. Trauma surgeons frequently act on their impressions before "official" readings are available. It has been demonstrated that surgical residents can accurately perform and interpret trauma ultrasound examinations. The purpose of this study was to evaluate the ability of senior surgery residents to interpret basic trauma radiographs. Interpretations of trauma radiographs (cervical spine, chest, pelvis, and CT of the brain) were recorded prospectively by the senior surgery resident present during trauma evaluations. These interpretations were compared with the findings of the radiologist as obtained from the official radiology report. Differing results were divided into clinically significant and clinically nonsignificant findings using defined criteria. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were determined. Interpretations of trauma radiographs by senior residents achieved an accuracy of 100 per cent for cervical spine radiographs, 95.9 per cent for chest radiographs, 98.0 per cent for pelvis radiographs, and 97.9 per cent for CT of the head. In aggregate senior residents interpreted trauma radiographs with 97.9 per cent accuracy. Differences that were considered clinically significant according to preset criteria occurred in 2.1 per cent of observations. We conclude that senior general surgical residents can accurately interpret trauma radiology, including CT of the brain. These results suggest that institutional policies for post-reading of trauma radiology should be reassessed.
外科住院医师在评估创伤患者时经常解读影像学检查结果,这些结果指导进一步的评估和侵入性操作。放射科医生对X光片的正式解读——“阅片后”——可能会延迟数小时甚至数天。创伤外科医生经常在获得“正式”解读之前就根据自己的判断采取行动。已经证明外科住院医师能够准确地进行和解读创伤超声检查。本研究的目的是评估高级外科住院医师解读基本创伤X光片的能力。在创伤评估期间在场的高级外科住院医师前瞻性地记录创伤X光片(颈椎、胸部、骨盆和脑部CT)的解读结果。将这些解读结果与放射科医生在正式放射学报告中得出的结果进行比较。使用既定标准将不同结果分为具有临床意义和无临床意义的发现。确定敏感性、特异性、阳性预测值、阴性预测值和准确性。高级住院医师对创伤X光片的解读在颈椎X光片方面准确率达到100%,胸部X光片为95.9%,骨盆X光片为98.0%,头部CT为97.9%。总体而言,高级住院医师对创伤X光片的解读准确率为97.9%。根据预设标准被认为具有临床意义的差异在2.1%的观察结果中出现。我们得出结论,高级普通外科住院医师能够准确解读创伤放射学检查结果,包括脑部CT。这些结果表明,应重新评估创伤放射学阅片后的机构政策。
