The study used the Delphi method to conduct two rounds of expert consultations involving 23 experts nationwide, aiming to establish the comprehensive index system for field epidemiological investigations of viral respiratory infectious diseases and determine the weights assigned to each index through the hierarchical analysis. Both rounds of consultation witnessed a 100% participation rate among all experts, with a coefficient of authority (Cr) reaching 0.89. The Kendall's W coefficients for assessing the importance and feasibility in both rounds were 0.108, 0.234, 0.439 and 0.427, respectively. Finally, an index system consisting of seven first-level indicators, 18 second-level indicators, and 36 third-level indicators was constructed for the technical guidelines governing field epidemiological investigations into viral respiratory infectious diseases, and the weight of each indicator was established. The index system constructed in this study has a high degree of scientificity, reliability and operability, but it still needs to be further adjusted and improved in combination with the epidemiological characteristics of viral respiratory infectious diseases.
本研究采用德尔菲法对全国23名专家开展两轮专家咨询，建立病毒性呼吸道传染病现场流行病学调查指标体系，并通过层次分析法确定指标权重。结果显示，两轮咨询专家积极程度为100%，权威系数（Cr）为0.89。两轮咨询重要性、可行性Kendall′s W系数分别为0.108、0.234、0.439、0.427（均P<0.05）。最终构建了7个一级指标、18个二级指标、36个三级指标的病毒性呼吸道传染病现场流行病学调查指标体系，并确立了各指标权重。本研究构建的指标体系具有较高的科学性、可靠性与操作性，但仍需进一步结合病毒性呼吸道传染病流行特点，不断进行调整与完善。.
