Abstract:

Objective To construct an evaluation index system for the monitoring and early warning capabilities of regional infectious diseases,providing a reference pathway for assessing the regional monitoring and early warning capabilities of infectious diseases. Methods From January to May in 2024,a preliminary indicator framework was initially established through literature retrieval from five databases including China National Knowledge Infrastructure(CNKI),Wanfang,VIP,PubMed,and Web of Science, sorting out laws,regulations,and technical documents related to monitoring and early warning,as well as group discussions. From July to September 2024,a two-round Delphi expert consultation was conducted. By combining the expert consultation weight method with the entropy weight method,the third-level evaluation indicators and their weights for regional infectious disease monitoring and early warning capabilities were determined. The scientific nature and rationality of the indicator system were assessed through the expert activity coefficient,expert authority,expert opinion coordination,and expert opinion concentration. Results A total of 15 experts participated in this study. The final indicator system covered four first-level indicators,sixteen second-level indicators,and forty-two third-level indicators. Among the four first-level indicators,the third-level indicators with the highest normalized weight values were respectively monitoring and early warning system construction(0.013 4),first-visit reporting rate of infectious diseases(0.016 2),implementation of various risk assessment methods(0.009 2),positive predictive value(0.012 4). The expert activity coefficients in the two rounds of inquiries were 100.00% and 93.33%,respectively,and the expert authority degree coefficients were all ≥0.75. The coordination coefficients in the second round were equal to or higher than those in the first round,and the differences were all statistically significant(all P<0.05). Conclusion This study uses the Delphi method to construct an evaluation index system for regional infectious disease surveillance and early warning capabilities,which can be scientifically and reasonably applied to the systematic assessment of such capabilities,providing a practical and feasible reference pathway for effectively enhancing the surveillance and early warning capabilities for infectious diseases.
