2018 Taiwan Hualien Earthquake-Disaster Lessons We Learned in the Emergency Department of a Tertiary Hospital.

BACKGROUND: On February 6, 2018, a magnitude-6.2 earthquake on the Richter scale struck Hualien, and that disaster killed 17 people and injured more than 300 people. Our hospital, the only tertiary hospital in eastern Taiwan, responded to a mass casualty incident (MCI) in two hours. Such a devastating earthquake infl uenced the health of the general population and the mental health of hospital staff. Thus, we aimed to analyze the medical problems in earthquake victims, the MCI response's operation, and the prevalence of post-traumatic stress disorder (PTSD) among healthcare providers. METHODS: We reviewed the medical records to investigate the information on the medical requirement of victims. Questionnaires were collected from emergency department staff regarding the operation of the MCI and the effect of regular MCI drills. For a survey of PTSD among healthcare providers, we used the Chinese version of the Davidson Trauma Scale for the psychiatric assessment. RESULTS: Among the 113 victims who entered the emergency room, almost 90% had a minor injury. The results of the operation of the MCI revealed that 71.5% of them knew the response process of the MCI and performed well. The hospital staff's mental health assessment showed 17.5% met the diagnostic criteria for PTSD one month after the disaster, and 3.2% met the criteria seven months after the earthquake. Personal psychiatric histories were the only risk factor for PTSD. CONCLUSIONS: Most earthquake victims presented to the emergency room with trauma injuries. Thus, we need to prepare more resources to manage surgical problems. To be well prepared for mass casualty events, the annual exercises play a signifi cant role. Besides, we can't ignore the mental health condition of healthcare providers after the disaster. We record this tragic earthquake's valuable experience and lessons and share them with others.
