A large number of isolation wards were built to screen suspected patients because of the outbreak of coronavirus disease 2019 (COVID-19). The particularity of the isolation wards would lead to more medical resource consumption and heavier hospital control tasks. Therefore, we adopted a vital signs telemetry system in the isolation wards to improve this situation.
Twenty sets of vital signs telemetry system were installed in the east district of the isolation area and the wards were used as the telemetry system wards (TSWs). The wards in the west district were used as the routine wards (RW). The daily telephone questionnaire was used to collect the frequency and time of ward rounds by medical staff and lasted for one week.
Within one-week survey, the average frequency of RW rounds was 3.00 ± 1.00 times per day, and the average time was 93.57 ± 66.25 min. The daily frequency of RW rounds was 0.428 ± 0.394 times per capita, and the time was 7.88 ± 2.36 min. There was a statistically significant difference in the time of ward rounds per capita, which presented that the daily time of TSW rounds per capita was shorter than that of RW rounds. No security events related to telemetry equipment were found throughout the study.
The application of vital signs telemetry system as an alternative to traditional ward monitoring is considered feasible. The use of telemetry system can significantly reduce the consumption of medical resources, the workload of medical staff along with the administration and labor cost for isolation wards. The telemetry system provides sensitive and reliable real-time monitoring for the key indicators used for disease judgment and can make an accurate warning of the patients with disease aggravation in time. Thus, it is worthy of promotion and wide application.
由于2019冠状病毒病（COVID-19）的爆发，大量隔离病房被建造用于筛查疑似患者。隔离病房的特殊性会导致更多医疗资源消耗以及更繁重的医院管控任务。因此，我们在隔离病房采用了生命体征遥测系统来改善这种情况。
在隔离区东区安装了20套生命体征遥测系统，这些病房用作遥测系统病房（TSWs）。西区的病房用作常规病房（RW）。通过每日电话问卷调查收集医护人员查房的频率和时间，持续一周。
在为期一周的调查中，RW病房的平均查房频率为每天3.00±1.00次，平均时间为93.57±66.25分钟。RW病房的每日人均查房频率为0.428±0.394次，时间为7.88±2.36分钟。人均查房时间存在统计学显著差异，表明TSW病房的每日人均查房时间短于RW病房。在整个研究过程中未发现与遥测设备相关的安全事件。
生命体征遥测系统作为传统病房监测的替代方案被认为是可行的。遥测系统的使用可以显著减少医疗资源消耗、医护人员的工作量以及隔离病房的管理和人力成本。遥测系统为疾病判断的关键指标提供灵敏可靠的实时监测，并能及时对病情加重的患者做出准确预警。因此，值得推广和广泛应用。
