Objective: We retrospectively investigated the degree of completion of the checklist during or immediately after diving accident, who were transported by a physician-staffed helicopter emergency medical service (HEMS). Method:From May 2016 to December 2020, we conducted a retrospective the diving accident checklist review of all patients with diving accident, who were transported by HEMS. If all questions of the diving accident checklist were answered, full marks were 40 points. Subjects were divided into two groups: the Arrest group, which included subjects who became cardiac arrest in prehospital setting, and the Control group. Results: A total of 86 patients with diving accident were transported by the HEMS. Among these patients, there were 16 subjects in the Arrest group and 70 in the Control group. Average total score in the Arrest group were significantly smaller than those in the Control group. Conclusion:Degree of completion of the diving accident checklist in cases with cardiac arrest was low in comparison with cases without cardiac arrest. To improve this, further approach based on several remedies will be required in the future.

Objectives: On July 3, 2021, a landslide occurred in part of Atami City, Shizuoka, Japan. Methods: The government of Shizuoka Prefecture requested the dispatch of Shizuoka Disaster Medical Assistance Teams (S-DMATs). Results: On day 2, the evacuees were evacuated into 2 hotels (A and B). Hotel A accommodated over 570 independent and dependent evacuees. Hotel B accommodated 44 dependent aged individuals, who lived in the same long-term health-care facility, together with their 11 caregivers. The evacuees in hotel B returned to the previous facility on day 10 without any specific medical problems. The evacuees in hotel A were managed in the guest rooms as family units. Individuals requiring care in guest rooms in hotel A became isolated because they could not call for help or walk. Furthermore, hotel guest rooms were not barrier-free. The S-DMATs supported the evacuees. Conclusions: Independent evacuees received the maximum benefits from the use of a hotel as a shelter. In contrast, it was difficult for dependent evacuees to benefit from the hotel as it is as a shelter when living alone in the hotel. Dependent evacuees required appropriate support to eat, walk, use the toilet, and keep themselves clean when using a hotel as a shelter.
