In 2019, the National Cheng Kung University (NCKU) Hospital Department of Emergency Medicine proposed an “island hopping” strategy for patients with special injuries to shorten patient transportation time. Specifically, through the coordination of prehospital care and posthospital treatment, patients can be assessed and stabilized t an early stage within a short time and transferred safely to a medical center for appropriate treatment. Since 2020, 55 critically injured patients with unstable vital signs have been referred to NCKU Hospital from remote areas through this transfer model, with 43 of them discharged from the emergency department alive and receiving follow-up treatment. In 2022, NCKU Hospital Department of Emergency Medicine collaborated with FarEastone Telecom in formulating Version 2.0 of the island hopping strategy, which incorporates smart emergency care through the use of 5G technology to facilitate the implementation of video communication, remote monitoring, smart ambulances, and smart wearable devices. The smart emergency care model improves the quality and efficiency of prehospital care. This model shall constitute a pilot study for incorporating 5G communication technology as a key instrument for emergency medicine to benefit more patients.
