Added value of radiologist consultation to family practitioners in the outpatient setting.

Abstract

PURPOSE: To measure the added value of a radiologist's consultation to the interpretation of radiographs previously read by a family practitioner. MATERIALS AND METHODS: The authors reviewed 1,674 chest and extremity radiographs previously read by a family practitioner and consulting radiologist. The 196 radiographs in which there was a discrepancy between the family practitioner's and radiologist's report were evaluated by a radiologist and family physician not involved in and blinded to the original interpretations. The overall accuracy of the participants was determined and differences statistically quantified. RESULTS: The overall sensitivity of the radiologists was greater than that of the family practitioners (92% vs 86%); specificity was not significantly different. For extremity examinations, there were no significant differences in accuracy of the radiologists and family practitioners; the sensitivity of radiologists for chest studies was considerably greater (89% vs 80%). Radiologic consultation was of particular value in the detection of pneumonia and masses. CONCLUSION: At a family practice center, the radiologist's role for extremity radiographs might be limited to individual consultation, with review of all chest radiographs.
