Accuracy of emergency radiograph interpretation by emergency physicians

The incidence of abnormalities in 1,869 sets of radiographs was recorded, and the accuracy of the interpretation of these films by emergency physicians was assessed. Abnormalities were most frequent in hip/femur (52.5%), thoracic spine (46.7%), and shoulder (44.8%) films and least frequent in skull (5.7%), cervical spine (14.9%), and foot (15.7%) films. The accuracy of interpretation by emergency physicians for all categories of films was 93.6%, with 1.8% false positives and 4.6% false negatives. Overreading of abnormalities occurred most often in thoracic spine (12.5%) and hip/femur radiographs (9.1%). The incidence of missing existing pathology was highest for abdomen (40.0%) and knee (31.6%) films. The overall accuracy of the emergency physicians in interpretation of emergency films was excellent. Increased didactics in particular areas of interpretive inaccuracies should be considered.
