Abstract： OBJECTIVE To explore the construction of an evaluation system for the response capacity of imported infectious dis-eases based on blind design,and to provide new methods and ideas for the health administrative department to test the emergency re-sponse capacity.METHODS Based on the background of an imported infectious disease epidemic in a district of Shanghai,a sin-gle-blind actual combat exercise was used to fully simulate the real epidemic situation,and the evaluation items and indicators were designed according to the relevant prevention and control schemes.RESULTS C hospital scored the highest,followed by A hospital,D hospital and B hospital.The highest score was 88 points,the lowest score was 62 points,and the average score was 75.75 points.The difference in scores among hospitals was statistically significant(χ2=21.697,P＜0.05).The top five communities in the total score of 15 community health service centers were F community,M community,K community,D community and H community.The highest score was 96 points,the lowest score was 45 points,and the average score was 70.67 points.There were significant differenc-es in the scores of each community(χ2=35.747,P＜0.05).CONCLUSION Through the exercise,the ability of medical institutions to respond to imported infectious diseases was effectively tested,and the feasibility of the exercise mode was verified,which provided a relatively reasonable,objective and scientific reference for the health administrative department to carry out health emergency exer-cise in the next stage.
