The construction of risk assessment system for centralized isolation medical observation sites for Covid-19 in Sichuan Province
Objective To understand the risk evaluation index system of centralized isolation medical observation sites and the weight of various indicators by building a risk evaluation system for novel coronavirus infection centralized isolation medical observation sites in Sichuan province.To identify the entry point to manage the risk of centralized isolation medical observation sites.Methods The Delphi expert method determined the risk evaluation index system of centralized isolation medical observation site for novel coronavirus infection,and the Analytic Hierar Process(AHP)hierarchical method of the expert group decision-making method calculated the weight of each index from March 20,2022 and June 15,2022.SPSS 22.0 statistical software was used to calculate the coordination coefficient of the expert survey,and the validity of the questionnaire was evaluated,the test level α=0.05.Results A total of 50 experts participated,the coordination coefficients of the two rounds of expert surveys were 0.38 and 0.43,respectively.Consistency of risk assessment matrix of the novel coronavirus infection isolation medical observation sites in Sichuan Province was 0.075 6.There were six first-level indicators in the system,the weight of the first-level indicators in turn were daily supervision(0.420 5),site hardware construction(0.195 5),nucleic acid testing(0.132 7),system and process(0.1001),personnel management(0.094 9),site environmental disinfection(0.0564),the secondary indicators included 34 in the system,the top six of the weight of second-level indicators in turn were one off room(0.156 0),drop-off point for quarantined personnel(0.093 7),residual chlorine monitoring(0.064 9),site selection(0.053 3),video surveillance(0.045 6),quarantined personnel nucleic acid(0.044 5).Conclusions It is an index system that comprehensively evaluates the risk of novel coronavirus infection centralized isolation medical observation sites in Sichuan Province.It is a more reasonable application of AHP hierarchical method in the evaluation of index system,which can improve efficiency and use AHP hierarchical method to make expert group decision-making in the prevention and control management of emerging infectious diseases.
