摘　　要：目的通过对实验室自动化系统运行数据进行分析,调整系统运行参数,改进工作流程,缩短标本周转时间。方法对3631份标本运行数据进行统计分析,计算标本周转时间,并进行超时原因分析。针对超时最严重的肿瘤标志物检测标本,改变检测流程,对流程改变前后标本周转时间进行比较。对人工干预标本按照原因进行分类,并针对问题进行改进,对改进前后人工干预标本数量及占比进行分析。结果标本周转时间超过4 h的标本共313份,占总标本数的8.62%。其中因标本交接超时的标本在超时标本总数中占比最大,为66.77%。肿瘤标志物标本检测流程改进后标本周转时间明显缩短,这类标本改进前占超时标本总数的52.47%,改进后为24.76%。条码异常、血量不足、离心问题3种原因造成的人工干预标本占总数的90.00%以上,针对3种主要原因,实验室采取对应措施后,人工干预标本占比下降至4.21%。结论实验室通过自动化系统运行数据分析,可针对性地解决瓶颈问题,提高工作效率。Objective To adjust operating parameters,optimize workflow and shorten turnaround time by analyzing operating data of laboratory automation system.Methods By analyzing operating data of 3631 samples,turnaround time of all samples was calculated and the causes that led to overtime samples were analyzed.The samples for tumor markers detection accounted for the largest proportion of overtime samples,and turnaround time of those samples was compared before and after optimizing workflow.The samples were classified by the reasons of artificial intervention.The quantity and proportion of the artificial intervention samples were analyzed before and after improvement.Results Turnaround time of 313 samples was over 4 hours,accounting for 8.62%in total samples.Untimely handover of samples was the primary cause,accnounting for 66.77%of all overtime samples.After the improvement of detection workflow,turnaround time of the sample for tumor markers detection was shortened obviously,and the proportion of those samples decreased from 52.47%to 24.76%.More than 90.00%of artificial intervention samples were caused by barcode problem,insufficient serum and centrifugation problem.In view of these three reasons,the laboratory took various measures to reduce the proportion of artificial intervention samples to 4.21%.Conclusion Through the analysis of laboratory automation system operating data,the laboratory can solve the bottleneck problem and improve the work efficiency.
