学校结核感染率筛查策略改良效果研究OA

Objective To evaluate the effectiveness of an improved screening strategy for tuberculosis(TB)infection rates in schools.Methods A total of 29 765 students from junior high and senior high grades in urban areas of the city were included from 2018 to 2019.Conventional methods were used for TB infection screening in the control group,while an improved method was implemented in the observation group.From 2020 to 2022,47 082 students were screened using the improved method.Positive rates of TB infection screen-ing were statistically analyzed.Results The TB infection positive rate was higher in the observation group compared to the control group,with a significant difference(P<0.05).From 2018 to 2022,there was a gradual decrease in TB infection positivity rates.Scores for TB prevention and treatment knowledge among students and healthcare workers increased significantly after training sessions(P<0.05).Scores showed an increasing trend over the years for both groups.Conclusion The improved screening method effectively increased the TB infection screening positivity rate,enhanced TB prevention and treatment knowledge among students and healthcare workers,and contributed to a decrease in TB infection rates,thereby effectively controlling tubercu-losis infections.
