OBJECTIVE: The aim of this study is to evaluate the accuracy levels of the emergency physicians (EPs) managing the patient in the interpretation of the urgent emergent pathological findings in thoracic and abdominal computed tomography (CT) scans.

METHODS: The EPs interpreted the CT scans of patients who visited the emergency department because of nontraumatic causes. Then, a radiology instructor made final assessments of these CT scans. Based on the interpretation of the radiology instructor, the false positive rate, false negative rate, sensitivity, specificity, positive predictive value, negative predictive value, and kappa coefficient (κ) of the EPs’ interpretations of the CT scans were calculated.

RESULTS: A total of 268 thoracics and 185 abdominal CT scans were assessed in our study. The overall sensitivity and specificity of the EPs’ interpretation of the thoracic CT scans were 90% and 89%, respectively, whereas the abdominal CT interpretation was 88% and 86%, respectively. There was excellent concordance between the EPs and the radiology instructor with regard to the diagnoses of pneumothorax, pulmonary embolism, pleural effusion, parenchymal pathology, and masses (κ: 0.90, κ: 0.87, κ: 0.71, κ: 0.79, and κ: 0.91, respectively) and to the diagnoses of intraabdominal free fluid, intraabdominal free gas, aortic pathology, splenic pathology, gallbladder pathology, mesenteric artery embolism, appendicitis, gynecological pathology, and renal pathology (κ: 1, κ: 0.92, κ: 0.96, κ: 0.88, κ: 0.80, κ: 0.79, κ: 0.89, κ: 0.88, and κ: 0.82, respectively).

CONCLUSION: The EPs are successful in the interpretation of the urgent emergent pathological findings in thoracic and abdominal CT scans.
