定期反馈法在入学新生查漏补种中的作用分析

Effect Analysis of Regular Feedback Method in Freshmen's Leak Finding and Revaccination

目的探讨定期反馈法在入学新生疫苗查漏补种中提高补种率的作用。方法将2017至2018学年什刹海辖区中学入学新生1387名,按学校随机分成2组,查验疫苗接种状况。将A组入学新生686名作为观察组,用定期反馈法对逾期未种疫苗新生进行补种;将B组入学新生701名作为对照组,采用常规入学查验证方法对逾期未种疫苗新生进行补种,对比分析补种率。结果逾期未种(即漏种)麻腮风联合减毒活疫苗(MMR)、A群C群脑膜炎球菌多糖疫苗(MPSV-AC)、脊髓灰质炎减毒活疫苗(bOPV)、重组乙型肝炎疫苗(HepB)、乙型脑炎减毒活疫苗(JE-L)、甲型肝炎灭活疫苗(HepA-I)进行补种,HepB两组均无漏种,观察组的MMR、MPSV-AC、bOPV、JE-L、HepA-I的一次补种率分别为100%,95.40%,100%,100%,96.15%,均明显高于对照组(71.05%,68.29%,70.59%,60.00%,57.14%),差异有统计学意义。结论定期反馈法对提高新生一次补种率有显著作用。

Objective to investigate effect of regular feedback method in improving revaccination rate of Freshmen's leak finding and revaccination. Methods divide 1387 freshmen of middle schools subjected to Shichahai from academic year 2017 to 2018 into two groups randomly according to school, and check vaccination situation. 686 freshmen in group A were treated as observation group, carry on revaccination for those overdue not vaccinated with regular feedback method; and 701 freshmen in group B as control group, carry on revaccination for those overdue not vaccinated with routine admission check method. Compare and analyze revaccination rate. Results carry on revaccination for overdue not vaccinated in two groups of MMR combined attenuated live vaccine, group A and C Meningococcal Polysaccharide Vaccine(MPSV-AC), oral poliovirus vaccine, recombinant hepatitis B vaccine, Japanese encephalitis vaccine, live and inactivated hepatitis A vaccine. No leakage for HepB of two groups. First time revaccination rate of MMR, MPSV-AC, bOPV, JE-L and HepA-I in observation group was 100%, 95.40%, 100%, 100%, 96.15%, significantly higher than control group(71.05%, 68.29%, 70.59%, 60%, 57.14%), difference showed statistical significance. Conclusion regular feedback method has significant effect to improve first time revaccination rate of freshmen, which is worthy of promotion.
