Abstract
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.
