天津市新型冠状病毒Omicron变异株预警指标的建立

Establishment of early warning indicators of SARS-CoV-2 Omicron variant in Tianjin

本研究采用德尔菲专家咨询法对全国12名专家开展问卷调查,确定天津市新型冠状病毒Omicron变异株预警指标体系及权重。三轮专家的积极系数均为100%,权威系数(Cr)为0.79,协调系数(W)分别为0.375、0.356、0.385(均P<0.05)。最终确立包括5个一级指标、10个二级指标、52个三级指标在内的Omicron变异株预警指标体系,并确立了各指标权重。

In this study,Delphi method was used to conduct a questionnaire survey on 12 experts to determine the indicators system and the corresponding weight for early warning features of SARS-CoV-2 Omicron in Tianjin.The positive indexes of experts in three rounds of consultations were both 100%.The experts′authority coefficient was 0.79.The Kendall′s W coordination coefficients were 0.375,0.356 and 0.385 respectively(all P<0.05).The indicators system for early warning features of 2019-nCoV Omicron variant had 5 first-level indicators,10 second-level indicators and 52 third-level indicators.The weight of each indicator was also determined.
