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。
Objective To understand the results of quality assessment of HIV / AIDS screening laboratories in Liaoning Province (hereinafter referred to as laboratories), strengthen its standardized management and improve its testing technology. Methods In 2008-2011, 224 laboratories in Liaoning Province were continuously tested for AIDS screening laboratory quality 4 times, and the results were analyzed. Results The excellent rate of examination and appraisal in Liaoning province increased year by year from 2008 to 2010, accounting for 62.9% (141/224), 74.1% (166/244) and 88.8% (199/224) respectively, with significant difference (χ2 = 40.472, P <0.01). In 2011, the excellent rate of evaluation fell by 14.2% (32/224) compared with that of 2010, the difference was statistically significant (χ2 = 15.286, P <0.01) There were 40,29,7 errors respectively, 35,16,4 cases were found in the report errors, 72,39,16 cases of the critical values were calculated, all of them decreased year by year, with significant differences (χ2 = 25.132, 29.031, 46.156, P <0.01). Conclusion Evaluation can reduce the probability of error in lab testing procedures, reports, critical value calculation, etc., and improve the quality of testing and management.
