摘要: 目的了解辽宁省艾滋病筛查实验室(以下简称实验室)质量考评结果,加强其规范化管理,提高其检测技术水平。方法于2008—2011年对辽宁省224家实验室连续进行4次艾滋病筛查实验室质量考评,并对结果进行分析。结果 2008—2010年辽宁省考评的优秀率逐年增加,分别为62.9%(141/224)、74.1%(166/244)、88.8%(199/224),差异有统计学意义(χ2=40.472,P<0.01);2011年考评优秀率比2010年下降了14.2%(32/224),差异有统计学意义(χ2=15.286,P<0.01);2008—2010年辽宁省考评中,发生检测程序错误分别有40、29、7家,发生报告填写错误分别有35、16、4家,发生临界值计算错误的分别有72、39、16家,均逐年减少,差异均有统计学意义(χ2=25.132、29.031、46.156,P<0.01)。结论考评可降低实验室检测程序、报告、临界值计算等错误发生概率,提高检测及管理质量。Abstract: ObjectiveTo evaluate the status of quality control in human immunodeficiency virus(HIV)-screening laborateries in Liaoning province for the improvement of standardized management of the laboratery.MethodsThe results of quality evaluation on 224 HIV-screening laboratories in Liaoning province from 2008-2011 were analyzed.ResultsThe excellence rate of HIV screening examination quality of the laboratories increased from 2008-2010 with significant annual differences(χ2=40.472,P<0.01).The quality excellence rate fell by 14.2% (32/224)in 2011 compared to 2010 with a significant difference(χ2=15.286,P<0.01).The error rates for testing procedures,reports,and cutoff value calculation reduced yearly with significant differences(χ2=25.132,P<0.01;χ2=29.031,P<0.01;χ2=46.156,P<0.01).ConclusionQuality evaluation for HIV-screening laboratory could reduce error in test procedures,reports,cutoff value calculation and improve the quality control of HIV-detection.
