Declarations
:
: According to Danish legislation, informed patient consent for the handover of medical records is required. However, this requirement can under certain circumstances be waived, for specific health science research, as was the case in the current study. The North Denmark Region approved the handover of the prehospital medical records (Reference ID 2023–002414) and the study is registered on the region’s list of ongoing projects (ID F2023-013). No further approval (e.g. by an ethics committee) is required for registry-based studies, such as the current study. These procedures are in accordance with Danish law, and all methods were carried out in accordance with relevant guidelines and regulations.
