Three China’s principal trainers, namely Dr. Li li, Dr. Cheng Jiaoying and Dr. Tu Xinzhi, have successfully conducted the TOT course at Beijing Obsterics and Gynecology Hospital, Capital Medical University. The course was organised by Simulation Medicine Professional Committee of Chinese Hospital Association, Beijing Obsterics and Gynecology Hospital, Capital Medical University and Laerdal China. The aim of this course was to escalate the number of local trainers, enabling them to run ICOE courses independently in China. Before the course, a virtual meeting was held to allow OGSM trainers to help them to refresh their knowledge and reinforce their teaching skills.
