Survey Participants

Participation in the survey was solicited from individuals who practiced in Canada or the United States, had personally completed more than 1500 US scans, and had PEM POCUS leadership positions or training. PEM POCUS leadership or training was defined as meeting one of the following criteria: 1) has completed a PEM POCUS fellowship, 2) serves as a PEM POCUS lead or director, 3) serves as a PEM POCUS fellowship director, or 4) serves as a general EM POCUS fellowship director and teaches PEM POCUS skills as a part of this role. This definition of “expert” was agreed upon by the study authors because it acknowledges the variety of training backgrounds in the current field of PEM POCUS and requires more scans than is typically required of a newly graduating PEM POCUS fellow. Study authors and contributing authors who met inclusion criteria for survey participation were included among those invited to participate. All had an expertise similar to that required for participation in the survey. Potential survey participants were solicited from the P2 Network mailing list and from PEM and EM POCUS fellowship directors listed on the Society of Clinical Ultrasound Fellowships and the Canadian Society of POCUS‐EM Fellowships websites,¹⁵, ¹⁶ which to our knowledge, offers the most comprehensive list of general and pediatric POCUS fellowships offered in Canada and the United States.
