Abstract
The year 2018 marks the 20th anniversary of emergency medicine (EM) as a medical specialty in Taiwan. Within the past two decades, Taiwan EM specialists have achieved numerous significant milestones in the development of the specialty in Taiwan, as described in this paper. The themes emerging from this paper assist in understanding the characteristics of Taiwan EM specialty, and may serve as a guiding model for other countries where the EM specialty is undergoing a similar process of development and optimization.
