[Appropriate allocation of resources for interhospital transfer in emergency medical service-is a physician in the dispatch center helpful?]

BACKGROUND: The number of interhospital transfers is constantly increasing because of specialization of medical facilities, capacity balancing between intensive care units as well as earlier rehabilitation procedures. This leads to an increase in requests for emergency physicians to accompany patient transfers. This study investigated whether clarification of interhospital transport by an emergency physician at the dispatch center can optimize the use of emergency services resources.
METHOD: All transport clarifications performed by a tele-emergency physician between 1 January 2018 and 31 December 2019 were retrospectively analyzed as well as the transport request forms. Furthermore, all data on the number and alarmed rescue resources for interhospital transfers in the city of Aachen from 2013 onwards were exported from the dispatch center databank and included in the evaluation.
RESULTS: In total 2333 requests for interhospital patient transfers from 2018 and 2019 were analyzed as well as 10,923 transports recorded from 2013 to 2019. The number of patient transfers accompanied by an emergency physician from 2013 to 2019 was significantly reduced from 786 (68.2%) to 495 (30.5%, p > 0.001). The correct resources of rescue vehicles and staff was requested in 1816 cases (77.8%). The urgency of emergency patient transfers was correctly evaluated in 567 (89.2%) cases. In total 526 assignments were carried out without an emergency physician and 315 of these patients were accompanied by a tele-emergency physician during transfer.
CONCLUSION: The immediate clarification of interhospital transport requests by an emergency physician at the dispatch center leads to a significant reduction in unnecessary medical accompaniment of patient transfers. The choice of an appropriate transfer vehicle and staff should not be left to the requesting hospital physician alone.
