Importance of a Collaboration Agreement in the Management of Physician-Staffed Helicopters.

OBJECTIVE: The purpose of this study was to present the management of 3 physician-staffed helicopters (helicopter emergency medical service [HEMS]) in 3 different requests in eastern Shizuoka based on a collaboration agreement and to investigate the current state of dispatches based on the agreement. METHODS: We investigated 3 incidents managed simultaneously by HEMS based on the collaboration agreement by inquiry to the bases, which were located in eastern Shizuoka, Yamanashi, and Kanagawa. We also investigated all records on the management of HEMS based on the collaboration agreement since the contract was made in 2014 by inquiry to the Shizuoka prefectural government. RESULTS: Three simultaneous flight requests were successfully completed. The total number of dispatches based on the collaboration agreement was 112 flights for 7 years from 2014 to 2020. The most frequent reason for request was overlapping request (n = 71). The prefecture with the highest number of requests was Shizuoka (n = 79), where medical resources were limited and the most frequent disease was trauma (n = 93). CONCLUSION: The present study reports how 3 HEMS were operated simultaneously for 3 different requests. To use medical resources effectively, including HEMS, the collaboration agreement among neighboring prefectures was very important, especially for areas in which medical resources are limited.
