Radiographer screening for incidental pulmonary emboli on routine contrast-enhanced computerised tomography scans at...

To introduce and assess effectiveness of a radiographer-led screening programme for the detection of unsuspected pulmonary emboli on routine contrast-enhanced computed tomography (CT), and to evaluate radiographer response to this extended role.

A training programme was devised for all radiographic staff working in CT. The screening service was introduced and monthly quality assurance performed with cumulative analysis of the first 2 years. Clinical effectiveness before and after screening was evaluated by comparing the time interval between the scan and the start of a clinical consultation for anticoagulant prescription. A satisfaction survey was sent to all participating staff.

Thirty-two radiographers completed the training. During the training period, the radiographer detection rate of incidental pulmonary emboli was 89%. Main, lobar, segmental, and subsegmental emboli were detected. The overall detection rate after full introduction of the programme was 92% for the first 2 years. The time interval between the scan and clinical consultation for anticoagulant prescription dropped from a mean of 1.5 days to a mean of 26 minutes and ensured that treatment was commenced at the same patient attendance. Eighty-four percent of staff completed the satisfaction survey and all were satisfied with the extended role.

Radiographer screening for incidental pulmonary emboli was effective and accurate. It resulted in immediate communication with the responsible physician and commencement of anticoagulation therapy at the same hospital attendance, creating a "one-stop" service. Radiographer satisfaction with the extended role was high.
