Construction of emergency medical service system based on 5G communication technology for large-scale social activities / 中华急诊医学杂志

ABSTRACT

Objective@#To develop medical emergency support information system for large-scale social activities based on 5G communication technology to improve efficiency of emergency medical services.@*Methods@#The project was completed in Hangzhou, China, from March 2016 to September 2019. Based on the medical service of large social activities, five information terminals are constructed, including on-site mobile terminal, on-board first aid terminal, expert remote consultation terminal, hospital terminal, and command dispatch center. The system can realize the real-time communication of medical information, patient's vital signs, audio, picture and video information, and can also make intelligent scheduling decisions for patients.@*Results@#5G Emergency Medical information System for Large-scale Social Activities has been completed, which consists of three parts command and control platform, on-site rescue platform, and evacuation support platform. The command and monitoring platform displays the information of on-site medical teams, ambulances, hospitals and experts through web pages, and realizes multi-party video communication at any time, as well as text, voice and image information of patients' current condition, so as to realize command, dispatch and display statistical summary information. On-site rescue terminal includes patient information input, video signal acquisition and physiological information acquisition equipment. It realizes multiple methods of patient information input, vital signs and physiological information acquisition, multi-angle video acquisition and transmission to the command center. The evacuation support platform includes vehicle emergency terminal, remote expert consultation terminal, hospital terminal and UAV system. Vehicle terminal can scan and transfer with on-site ambulance team, record physiological information during transit, and also acquire and transmit monitor, electrocardiogram and ultrasound information. Hospital terminals can obtain patient information at the first time and prepare for first-aid in hospital. The remote expert terminal can be dispatched by the command center and the hospital terminal, and can join the remote consultation at any time. Unmanned aerial vehicle (UAV) system can transfer medical material between any locations.@*Conclusions@#This system can guarantee the patients to be transported from the scene to the ambulance and finally to the hospital during the large-scale social activities. In the whole process, the information transmission and dispatching decision-making are initially realized, and the statistical report forms can be made. However, to fully exert its advantages, it still needs the support of the complete 5G network and continuous optimization in real scenarios.
