学校结核感染率筛查策略改良效果研究

Improvement of screening strategy for tuberculosis infection rate in schools

目的探讨学校结核感染率筛查策略的改良效果。方法选取2018-2019年该市城区各中学初一年级及高一年级的29765例学生,采用常规方法结核感染率筛查为对照组,采用改良方法结核感染筛查为观察组;选取2020-2022年该市城区各中学初一年级及高一年级的47082例学生,采用改良方法结核感染筛查,统计分析结核感染率筛查的阳性率情况。结果观察组结核感染阳性率高于对照组,差异有统计学意义(P<0.05),2018-2022年结核感染阳性率呈逐渐下降趋势。学生结核病防治知识考试分数培训后均高于培训前,医务人员结核病防治技能考核分数培训后均高于培训前,差异均有统计学意义(P<0.05),2018-2022年医务人员及学生培训前后考核分数随着年份的增加呈升高趋势。结论改良方法有效提高了结核感染筛查阳性率、学生结核病防治知识、医务人员结核病防治技能,结核感染阳性率降低,结核病感染得到有效控制。

Objective To evaluate the effectiveness of an improved screening strategy for tuberculosis(TB)infection rates in schools.Methods A total of 29765 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 2022,47082 students were screened using the improved method.Positive rates of TB infection screening 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 tuberculosis infections.
