上海市2010年部分基层医院血液检验质量分析

目的通过统一组织的调查,了解和评价上海地区二级乙等以下医疗机构血常规检验质量。方法用2个批号的经固定新鲜血对257家医疗机构血液分析仪进行白细胞(WBC)、红细胞(RBC)、血红蛋白(Hb)、红细胞压积(HCT)和血小板(PLT)项目考核;用2份来自临床病例的血涂片对上述医疗机构实验室进行WBC分类和异常细胞形态检查的考核。结果血液分析仪不合格率为4.7%,尚未配套血液分析仪的医院占1.9%;血涂片细胞形态学检查的合格率为25%。结论上海市二级乙等以下医疗机构血常规检验质量仍存在较大问题,尤其是血涂片细胞形态学检查质量需进一步提高。基层医院血常规检查质量应引起各方面的重视。
