**7. Conclusions**

In conclusion, the findings in this report indicate that the ability in all elements of CSCATTT, particularly expertise in command and control, communication, collaboration and coordination, and situation assessment, improved in all groups of EPs systematically and after each scenario. The 3LC method also enabled all participants to create new perspectives and innovative measures, which improved the overall managemen<sup>t</sup> of scenarios on the final day. The 3LC increases the ability, knowledge, and attitude of Thai emergency physicians in managing MID. It also enables them to lead emergency managemen<sup>t</sup> in an unexpected situation, as alternative leaders in a flexible surge capacity-response system [10,30].
