The primary objective of this initial report is to address the following questions: Under what circumstances do clinical teams at satellite locations utilize the 5G RHS? Does the implementation of 5G RHS result in significant clinical enhancements? Furthermore, additional analyses will be conducted to assess specific improvements in various use cases (e.g., emergency room, diagnosis, treatment, task guidance, and medical education) and to examine whether factors such as the expertise of central physicians, patient and physician locations, and the timing of calls influence clinical outcomes.

Background: Augmented Reality (AR) has undergone rapid development in recent years, gaining prominence in healthcare, especially when coupled with 5G internet technology. This study delves into the integration of 5G Augmented Reality in emergency medicine, with a focus on its impact on clinical outcomes.

Methods: This study will utilize the 5G-based Remote Healthcare System (5G RHS) to connect four satellite Emergency Room (ER) teams with central experts to assess its effectiveness in critical cases. Data will be collected from July 2022 to June 2023 to address key research questions, including the circumstances prompting the use of 5G RHS, the extent of clinical improvement achieved, and the influence of central physician expertise, patient and physician locations, and calling time on clinical outcomes.
