Participants

We approached trainers after the SBL sessions concluded at the Percutaneous Cardiovascular Revascularization (PCR) annual meeting on 21-23 May 2019. Seventeen trainers participated in the study (Table 1) with a median age of 50 years (range 35-60 years). The median experience was 24 years as a physician with 21 years of specialty practice in cardiology, and the median experience as an instructor in SBL was seven years (range 0-16 years). Sixty percent of the trainers stated they had no specific training in SBL theories or design principles. The remaining 40% of the trainers declared they only had the classroom training for facilitating learning. Study participants came from ten countries (Australia, England, France, Germany, Italy, Japan, Norway, Poland, Switzerland, and Thailand), and all were male. This study was approved by the Institutional Review Board of Terumo Corporation (Tokyo Japan) according to the guidelines for research in medicine involving the human, Japan Ministry of Education and the Japan Ministry of Health and Labour, ver. 2017 (HPE-2018-TIS01). All participants signed a written consent that explained the research project and its objectives, methods, procedure, and analysis. Data were anonymized.
