广西地区新生儿甲状腺功能低下可疑阳性的召回情况分析及对策

Analysis of Guangxi suspected positive congenital hypothyroidism newborn recall and countermeasure

目的分析广西地区新生儿甲状腺功能低下(congenital hypothyroidism,CH)可疑阳性的召回情况及未召回原因,制定对策以提高召回率。方法对2012-2013年广西新生儿疾病筛查中心新生儿CH筛查召回情况进行分析,以各合作单位送检的所有新生儿为对象,测定血样中TSH含量,筛查结果阳性者及时电话召回,以血清标本复查确诊。结果 2012-2013年广西新生儿疾病筛查中心共筛查488 519例,初筛阳性7 777例,召回6 559例,确诊CH 321例,发病率1/1 522。不同初筛结果、不同生活环境可疑患儿召回率之间差异有统计学意义(P<0.05);不同性别、不同产院之间可疑患儿召回率差异无统计学意义(P>0.05);未召回原因主要是经济问题。结论广西地区地理环境因素及家长对新生儿疾病筛查的认识对新生儿疾病筛查率和召回率有极大的局限性。
