Are accident and emergency consultants as accurate as consultant radiologists in interpreting plain skeletal radiographs taken at a minor injury unit?

Abstract

The objective of this study was to compare the accuracy of an accident and emergency (A&E) consultant in interpreting plain skeletal radiographs with that of a consultant radiologist (CR). It took the form of a retrospective study of 2133 radiographs taken in a Minor Injury Unit (MIU). A&E consultant reports on these films were compared with those of a CR and also with a gold standard. The A&E consultant diagnoses achieved an accuracy of 98.5% (CR 97.8%), sensitivity of 97.8% (CR 98.1%), specificity of 98.8% (CR 97.7%), positive predictive value of 97.3% (CR 95.1%) and negative predictive value of 98.97% (CR 99.07%) (gold standard of 100%). In conclusion, the A&E consultant reports of plain skeletal radiographs generated from an MIU were as accurate as those of a consultant radiologist. This could have significant implications for the wet reporting of A&E departmental radiographs.
