帕累托图分析法在不合格标本质量控制持续改进上的应用

Application of Pareto chart analytical method in continuous improvement of unqualified specimens quality control

目的探讨检验科分析前过程中不合格标本产生的原因,找出不合格的关键少数原因、次要多数原因及其关系,为改进不合格标本的现状提供依据,提高检验科分析前质量控制水平。方法应用帕累托图分析法对该院2015年第3、4季度的不合格标本进行分类统计。结果分析这2个季度不合格标本产生的主要原因,进行人为干预。通过对临床标本采集的培训和宣教、标本流程的改进,不合格标本的主要原因、次要原因、一般原因发生了相互转换,不合格标本的数量减少,为后续分析前标本管理的进一步改进提供了依据。结论通过帕累托图分析法可找出标本不合格的主要原因,可集中力量对主要原因进行纠正和验证,针对不同科室的不同原因精准发力,有效促进分析前质量控制的持续改进。

Objective To analyze the reasons causing the unqualified specimens during the pre-analysis process of clinical laboratory department and to find the key minority reasons and secondary majority reasons and their relationship in order to provide the basis for improving the status quo of unqualified specimens and increasing the pre-analysis quality control level of clinical laboratory.Methods The unqualified specimens in our hospital from the third quarter to the fourth quarter 2015 were performed the classified statistics by the Pareto chart analytical method method.Results The main seasons of unqualified specimens during the two quarters were analyzed,then the artificial intervention was performed.By the training,propaganda and education of the clinical specimen collection,improvement of specimen process,the primary causes,secondary causes and general cause produced the interconversion,the number of unqualified specimens were reduced,which provided a basis for the further improvement of following pre-analysis specimens management.Conclusion Using the Pareto chart analytical method can find out the main causes of specimen disqualification,concentrates the force to correct and verify the main causes and accurately taking force to effectively promote the continuous improvement of pre-analysis quality control by aiming at different causes in different departments.
