To report the experience of health QR code application in Chengdu's anti-epidemic measures including circle-layer management, hospital triage system and healthcare plan for quarantined pregnant women and children during the summer outbreak of SARS-CoV-2 Delta strain in 2021 and to evaluate these measures.
We comprehensively summarized Chengdu's health code application in the circle-layer management (a set of stringent confinement measures of places confirmed cases and close contacts have recently been to and less strict quarantine measures of surrounding areas), hospital triage system, and healthcare plan for quarantined pregnant women and children. We also assessed the effectiveness or efficiency of these measures by analyzing the number of different cases with confirmed COVID-19 infections or epidemiological history, the attitude of quarantined pregnant women toward the summer outbreak and healthcare services, as well as the time needed for obtaining epidemiological history and accuracy of health-code-based hospital triage system.
The circle-layer management lasted 15 days and ended with no community or nosocomial transmission happened. Approximately 70 pregnant women and 600 children below 6-year-old were quarantined. Four home visits and two patient transfers were performed. Online survey indicated that about 80% of quarantined women felt satisfactory about the healthcare service. The novel triage system identified 137/221 (61.99%) patients with epidemiological history from patients with yellow health code, and 71/4504 (1.57%) patients from patients with green health code in our hospital (p < 0.001). The health QR code markedly outperformed the traditional methods in the efficiency experiment of obtaining epidemiological history (3.52 ± 0.98 vs 78.91 ± 23.18 seconds, P < 0.001).
The circle-layer management has successfully and precisely prevented the spread of the summer outbreak of COVID-19 in Chengdu. The health-code-based triage system showed great effectiveness and efficiency in triaging patients with epidemiological history. The healthcare services for quarantined pregnant women has basically met their needs.
报告2021年夏季新冠病毒德尔塔毒株疫情期间，成都健康码在圈层管理、医院分诊系统以及隔离孕妇和儿童医疗保健方案等抗疫措施中的应用经验，并对这些措施进行评估。
我们全面总结了成都健康码在圈层管理（对确诊病例和密切接触者近期去过的场所采取一套严格的封闭措施，对周边区域采取较宽松的隔离措施）、医院分诊系统以及隔离孕妇和儿童医疗保健方案中的应用情况。我们还通过分析新冠病毒感染确诊病例或有流行病学史的不同病例数量、隔离孕妇对夏季疫情及医疗服务的态度，以及获取流行病学史所需时间和基于健康码的医院分诊系统的准确性，来评估这些措施的有效性或效率。
圈层管理持续了15天，结束时未发生社区传播或院内传播。约70名孕妇和600名6岁以下儿童被隔离。进行了4次家访和2次患者转运。在线调查显示，约80%的隔离孕妇对医疗服务感到满意。我院新型分诊系统从黄码患者中识别出137/221（61.99%）有流行病学史的患者，从绿码患者中识别出71/4504（1.57%）有流行病学史的患者（p<0.001）。在获取流行病学史的效率实验中，健康码明显优于传统方法（3.52±0.98秒对78.91±23.18秒，P<0.001）。
圈层管理成功且精准地防止了成都夏季新冠疫情的传播。基于健康码的分诊系统在分诊有流行病学史的患者方面显示出了巨大的有效性和效率。隔离孕妇的医疗服务基本满足了她们的需求。
