To limit the epidemic of COVID-19, most countries and regions have adopted the policy of quarantine, providing an opportunity for the development of telemedicine. This study aims to develop a telemedicine system within a quarantined district and validate its effectiveness and safety in managing a variety of diseases within the population. Appling the private network and specialized set, telemedicine system and service process were constructed in the quarantine district. Based on the patients’ conditions, the staffs supplied kinds of medical service for the patients in the quarantine district. The basic characteristics and results of patients in the quarantine area who used telemedicine system during January to September 2022 were statistically analyzed. Within this period, 2410 cases were included in this study, among which, 1803 patients directly saw a doctor by the Internet hospital in the Internet hospital of telemedicine system, 607 patients used telemedicine system, 166 patients achieved referral to a specific hospital via telemedicine system, and 162 cases made further consultation, with no infection cases in the quarantine zone and no death cases. The six most occurred diseases were respiratory disease (20.6%), ophthalmology and otorhinolaryngology (12.9%), cardiovascular diseases (12.7%), digestive system disease (12.5%), dermatological diseases (10.6%), and metabolic and endocrine diseases (7.6%). The top three referred cases were obstetric diseases (19.3%), others (12.0%) and respiratory disease (10.2%). There were statistically significant differences between the diseases of the cases using telemedicine system with and without referral (P < 0.001). It is feasible, effective and efficient to construct and use telemedicine system in quarantine area. It is an approach to manage many patients by indirectly contact. With the solution of follow-up related problems and the application of novel technologies, telemedicine may usher in greater development.

Background: Using 5th Generation Mobile Communication (5G) and cloud Technology to design a smart bracelet for key populations during the epidemic, improve the efficiency of epidemic prevention and control, and limit epidemic transmission. Methods: A thermosensitive metal temperature sensor and positioning chip were used to develop a smart bracelet. The smart bracelet monitored the temperature changes and real-time positioning of 40 patients at different time points. To validate the efficacy of smart bracelets in monitoring key populations, a comprehensive assessment of their consistency and accuracy was performed using fixed-point data collected by high-precision mercury thermometers and cameras. Results: The body area network (BAN)-based smart bracelet's temperature monitoring during the COVID-19 epidemic was compared to that of a mercury thermometer at different time points of the key population, with ICC=0.883, showing a high consistency and accuracy. Analysis of the real-time positioning data obtained from smart bracelets and camera monitoring, yielded highly accurate outcomes, with a Kappa value of 0.494, a sensitivity of 46.4%, a specificity of 98.7%, and an accuracy of 0.968. Conclusion: 5G、BAN and other technology-based smart bracelets are feasible for temperature and displacement monitoring of key populations, can replace the duties of medical personnel in certain wards, reduce contact, and have the role of reducing hospital infection.
