摘　　要：目的　探讨在结核病控制规程中痰涂片室间质控的新模式。方法　以新登记肺结核病人痰涂片为质控重点 ,在区县级实验室之间 ,开展双盲初级室间质控 ,省级参比室进行终级质控考核。结果　在不增加经费投入情况下 ,地区质控覆盖率可达 10 0 % ,每年约 5 0 %新登记肺结核病人痰涂片置于质量监控之下。镜下阳性符合率从本课题实施前 99.0 %～ 10 0 %下降至 97.1%～ 98.3% ,阴性符合率由 99.4 %～ 99.9%下降至 98.5 %～ 99.1%。结论　采用双盲法开展同级间室间质控 ,是经济可行的一种间接督导方式 ,可有效地扩大质控范围和质控频率 ;两级双重室间质控使质量控制程序更趋严格 。Objective To discuss a new model of Quality control (QC) system for sputum smear microscopic examination laboratory in tuberculosis.Methods The sputum smears of newly registered tuberculosis patients were key points of QC system.To carry out elementary QC with double blind in district (county) class sputum smear microscopic examination laboratory .The province class reference laboratory was set for final QC exam.Results In keeping current cost,local QC rate could reach to 100%,about 50% sputum smears of newly registered tuberculosis patients were supervised under QC system every year.The positive detection rate was decreased from 99.0%～100% to 97.1%～98.3%,and the negative detection rate was decreased from 99.4%～99.9% to 98.5～99.1%.Conclusion Using double blind to carry out QC in equal class examination laboratory is an economical supervise method.It can spread QC scope and QC frequency efficiently.Two different class examiniation laboratory mate the QC process more strictly,which can play an important role in tuberclosis programe.
