摘   要：針对突发疫情带来的患者线下交叉感染风险与医护人工排查患者工作量激增的社会公共安全问题，通过文献法、流行病学理论、专家咨询与主观赋权法（医院感控、呼吸内科、危急重症科、疾病控制中心等部门的专家）、人机交互设计、用户测试与可用性评估等方法，进行了突发疫情疑似症状风险自查内容、可供选项、风险权重与阈值以及人机交互设计研究，制定了疑似病案筛查与患者分类居家观察、隔离和立即就诊的早期防控策略，设计了疑似症状风险评估人机交互应用与筛查模式并上线推广使用. 结果表明在突发疫情爆发早期，疑似症状风险自查应用为民众提供了简单易行的临床判断科学依据，一定程度上缓解了民众盲目焦虑、线下交叉感染风险以及医护人工排查工作量，为未来新型传染病疫情防控，提供了线上疑似症状风险筛查分类与线下患者分流就医的防控策略与人机交互设计参考.

Abstract：A surge in the workload of the hospital for testing potential patients and an increased risk of cross-infection among patients due to emergent epidemic， poses a critical social public safety problem. Through the methods including literature review， epidemiological theory， expert consultation，subjective weighting （involving experts from the Departments of Infection Control， Respiratory Medicine， Critical Care， and the Center for Disease Control）， human-computer interactive design，user test，usability evaluation and etc，the content of online affected risk self-check application， available options， risk weighting and threshold， and human-computer interactions of high usability are investigate. An early prevention and control strategy is proposed for suspected cases screening and reliable suggestions to self-monitor at home， self-isolate， or seek immediate medical attention. The human-computer interaction application and screening model for suspected symptom risk assessment are designed and promoted online. The results indicate that in the early phase of emergent epidemic， the online emergent epidemic affected risk self-check application can provide a simple and feasible scientific basis for clinical judgement， alleviate the social panic， resolve the shortage of manual screening， and reduce the risk of cross-infection among patients by providing a straightforward， easy-to-understand scientific protocol. It provides references for future new epidemics prevention and control through online classification and offline triage of patients of suspected symptoms.
