                 Implementing ultrasound in Dutch emergency departments after a two-day training 101
We excluded EPs who already performed PREP or eFAST US examinations, at least once a month, preceding the course.
Included subjects received written information in more detail in advance and written in- formed consent was given prior to the interview. Further inclusion of subjects was continued until no more new codes were determined during the interview process and data saturation was reached.
Subjects were interviewed at their own workplace by a trained interviewer (EvH). The in- terviews were conducted face-to-face in a secluded room without disturbances. Open-ended questions based on the initial topic list were used to initiate the conversations. The interviews were conducted in Dutch and audio-recorded. The mean duration of the interviews was 26 minutes. Notes on non-verbal communication were taken. Member checks were performed: every participant was invited to read and comment on a summary of the transcription.
