2009年河南省急性弛缓性麻痹病例家长回忆免疫史真实性调查

Study on the authenticity of the parents' memory on acute flaccid paralysis cases' immunization status in Henan province in 2009.

目的评价2009年河南省急性弛缓性麻痹(AFP)病例"家长回忆"获得的脊髓灰质炎疫苗免疫史的真实性,分析AFP病例免疫史调查采用家长回忆方式的影响因素。方法通过调查273例依靠"家长回忆"方式获得免疫史病例的接种记录,得到病例真实的免疫史,进而评价依靠"家长回忆"方式获得免疫史的真实性,同时访谈原调查员,分析原免疫史调查采用家长回忆方式的影响因素。结果依靠"家长回忆"获得免疫史的正确率为46.1%。免疫史调查采用家长回忆方式而未利用接种证主要原因是"没有随身携带,病例不愿回家取或随后提供",未利用接种卡主要原因是"当时无法查阅接种卡"。结论家长回忆获得的免疫史不能准确代表真实的免疫状况,查验接种记录应作为AFP病例免疫史调查的首要途径。
