Accuracy of interpretations of emergency department radiographs: effect of confidence levels.
We conducted a prospective study to assess the relationship between the interpretive agreement rate for emergency department radiographs and the degree of interpretive confidence. We hoped to identify a subset of ED radiographs that did not require mandatory review by a radiologist. For each of the 1,872 plain radiographs studied, emergency physicians assigned a confidence level to the interpretation before comparing it with the radiologist's dictated report. ⋯ No subset of radiographs had 100% agreement. Treatment was potentially altered in 38 patients as a result of the interpretive disagreement that occurred in 2% of studied radiographs. We conclude that the interpretive agreement rate increases in relation to interpretive confidence but that confidence levels cannot safely exclude certain radiographs from mandatory review by a radiologist.
