Japan experienced several major disasters in 2018.

Evaluation of medical response was conducted and problems determined to solve for future response.

An evaluation conducted on DMAT responding report of Northern Osaka Earthquake, West Japan Torrential Rain Disaster, Typhoon Jebi, and Hokkaido Iburi East Earthquake.

DMAT responded 58 teams for Osaka Northern Earthquake, 119 teams for West Japan Torrential Rain Disaster, 17 teams for Typhoon Jebi, 67 teams for Hokkaido Iburi East Earthquake. At the Osaka Northern Earthquake, by comparing the report of seismic diagnosis, results and, a magnitude of each region, hospital damage was evaluated. At the West Japan Torrential Rain Disaster, a flood hazard map was used to expect inundation at hospitals. At the Hokkaido Iburi East Earthquake, information of hospital generator was gathered and planned assistance for loss of power. Water supply cessation in the West Japan Torrential Rain Disaster and loss of power in the Hokkaido Iburi East Earthquake influenced hospital functionality. More precise preparation for hospital management in the event of a loss of power and water supply situation required in not only in local government but also each hospital. For the West Japan Torrential Rain Disaster, we experienced the same type of major disasters in the past, but could not manage accordingly. For the Hokkaido Iburi East Earthquake, we applied what was learned from the West Japan Torrential Rain Disaster.

Disaster medical operation was supposed to be managed with information from the Emergency Medical Information System (EMIS). However, 2018 disasters provided lessons that require a full understanding of disaster prior information and expected disaster damage information to manage disaster assistance. To accomplish effective disaster assistance, information must be gathered of supplies and assistance required by hospitals. An effective system to facilitate lessons learned needs to be developed

The aim of this study was to identify disaster medical operation improvements from the 2016 Kumamoto Earthquake (Kumamoto Prefecture, Japan) and to extract further lessons learned to prepare for future expected major earthquakes.

The records of communications logs, chronological transitions of chain of command, and team registration logs for the Disaster Medical Assistant Team (DMAT), as well as other disaster medical relief teams, were evaluated.

A total of 466 DMAT teams and 2,071 DMAT team members were deployed to the Kumamoto area, and 1,894 disaster medical relief teams and 8,471 disaster medical relief team member deployments followed. The DMAT established a medical coordination command post at several key disaster hospitals to designate medical coverage areas. The DMAT evacuated over 1,400 patients from damaged hospitals, transported medical supplies to affected hospitals, and coordinated 14 doctor helicopters used for severe patient transport. To keep constant medical and public health operations, DMAT provided medical coordination management until the local medical coordination was on-track. Several logistic teams, which are highly trained on operation and management of medical coordination command, were dispatched to assist management operation. The DMAT also helped to establish Disaster Coordination and Management Council at the prefectural- and municipal-level, and also coordinated command control for public health operations. The DMAT could provide not only medical assistance at the acute phase of the disaster, but also could provide medical coordination for public health and welfare.

During the 2016 Kumamoto Earthquake, needs of public health and welfare increased enormously due to the sudden evacuation of a large number of residents. To provide constant medical assistance at the disaster area, DMAT, logistic teams, and other disaster medical relief teams must operate constant coordination at the medical headquarter command. For future expected major earthquakes in Japan, it will be required to educate and secure high enough numbers of disaster medical assistance and health care personnel to provide continuous medical and public health care for the affected area residents.
