Interpretation of chest radiographs, although clinically highly impactful, entails a disproportionate amount of work relative to low reimbursement for these studies. Increasing volumes of chest radiographs in the thoracic imaging division of an academic radiology practice led to incorporation of two radiology extenders (REs) to draft reports of chest radiographs. We evaluated the difference in productivity and accuracy of the reports drafted by REs versus radiology trainees. Impact on throughput was analyzed by measuring flow rates (number of radiograph interpretations finalized per hour) for four subspecialist attending thoracic radiologists under three conditions: independent interpretation, reviewing RE-drafted cases, and reviewing resident-drafted cases. Improvements were calculated as change in flow rates for the latter two conditions compared with an independent interpretation. Accuracy of RE-drafted reports was compared with that of junior residents by evaluating their draft reports for the same chest radiographs (n = 49). A blinded judging panel of three attending radiologists scored these reports using the 3-point RADPEER scoring system; the original report dictated by an attending radiologist served as the reference standard. RADPEER scores were compared between the REs and residents. Flow rates improved significantly (P < .05) by 52% for RE-drafted cases versus a small improvement (17%) for resident-drafted cases compared with independently completed cases. RE-drafted cases generated 36% greater efficiency for attending radiologists compared with resident-drafted cases (P < .05). There was no significant difference in accuracy scores between RE-drafted and resident-drafted reports. RE-drafted reports were finalized more rapidly by attending radiologists with insignificant differences in discrepancy rates compared with resident-drafted reports.
