摘　　要：目的评价运用六西格玛(6σ)管理方法缩短门诊凝血项目实验室内样本周转时间(TAT)的效果。方法通过界定、测量、分析、改进、控制五大步骤,对门诊凝血项目实验室内TAT较长的主要原因进行分析,有针对性地制定改进措施,并落实。比较改进前后TAT的差异。结果改进后,门诊凝血项目实验室内TAT中位时间由改进前的127.5 min缩短到66.0 min,达标率由47.0%提高到93.9%,百万机会缺陷数(DPMO)由53.0035%降低到6.1002%,改进前后的TAT和TAT达标率的差异均有统计学意义(P<0.05)。结论6σ管理方法可显著缩短门诊凝血项目实验室内TAT,有助于优化检验流程,值得临床实验室推广。Objective To investigate the effect of six sigma(6σ)management on shortening outpatient coagulation test’s turn-around time(TAT)in clinical laboratory.Methods Through the 5 steps(define,measure,analyze,improve and control),the main causes of outpatient coagulation test’s TAT in clinical laboratory delaying were investigated and analyzed,with following pointed improvement measures formulated and implemented.The difference between before and after improvement was compared.Results After improvement,the outpatient coagulation test’s TAT in clinical laboratory was shortened from 127.5 min to 66.0 min in median,the qualified rate was increased from 47.0%to 93.9%,and defects per million opportunity(DPMO)was reduced from 53.0035%to 6.1002%.Both differences in TAT and TAT compliance rates between before and after improvement had statistical significance(P<0.05).Conclusions The application of 6σmanagement shortens the outpatient coagulation test’s TAT in clinical laboratory and could help with optimizing the inspection process with the value of promotion in clinical laboratory management.
