CT colonography: who attends training? A survey of participants at educational workshops.

To obtain information regarding the demographics of attendees of computed tomography colonography (CTC) training workshops organized by the European Society of Gastrointestinal and Abdominal Radiology (ESGAR), in particular their prior expertise and current practice.Attendees at five CTC training workshops conducted in Edinburgh (UK), Malmo (Sweden), Amsterdam (Netherlands), Pisa and Stresa (Italy) between February 2007 and April 2010 completed an online questionnaire. Responses were collated and descriptive statistics produced.Three hundred and forty-eight delegates responded; a response rate of 73%. There was wide geographical variability encompassing 20 European member-states and seven countries outside Europe. The overwhelming majority were radiologists (336; 97%). Of the respondents, 299 (86%) were already interpreting CTC in clinical practice but of these, 158 (54%) had no prior formal training in CTC whereas 21 (8%) had attended a previous workshop. Furthermore, of those reporting CTC, 227 (76%) had interpreted fewer than 50 cases.Despite political imperatives for other groups to interpret CTC, the vast majority of those attending training are radiologists. Worryingly, a significant proportion of these are apparently reporting CTC in clinical practice without adequate training.
