Performance evaluation and study on open assembly line system in medical laboratory

目的 通过开放式流水线系统运行后核心数据和性能的分析评估,探讨实验室开放式自动化系统的优势及其可持续优化.方法 收集上海中医药大学附属曙光医院2017年4至10月生化、免疫的运行数据.（1）各种流水线方案的成本分析;（2）应用流水线前后工作流程分析;（3）应用流水线前后样本采集量分析;（4）应用流水线前后检测周转时间数据分析;（5）应用流水线前后人员配置分析;（6）应用流水线前后样本复检分析.结果 （1）各类方案中开放式流水线的硬件成本约800万,无需增加场地,综合成本最低,后续成本可接受;（2）应用流水线后检验流程有较大简化;（3）应用流水线后实际样本采集数减少31.85％;（4）应用流水线后各项目的检测周期均有所下降,平均检测周期降低了32 min;（5）应用流水线后样本前处理人员可减少50％,仪器操作人员未变化;（6）应用流水线后除了灰区和危急值结果外各类原因的样本复检数量均有所上升,保证了结果可靠性.结论 通过开放流水线系统运行后核心数据分析,实验室在检测周期、样本采集、检测效率上明显提高.

Objective To investigate the advantages and continuous optimization of laboratory automation system through analysis and assessment of the core data and performance after the application of open assembly line.Methods Collect the data of biochemical and immunoassay in Shuguang Hospital attached to Shanghai University of Traditional Chinese Medicine from April to October 2017.（ 1 ） Cost analysis of the assembly line schemes;（2） Analysis of workflow before and after the application of assembly line;（3） Analysis of the volume of samples collecting before and after the application of assembly line ;（4） Analysis of TAT data before and after the application of assembly line; （ 5 ） Analysis of staffs allocation before and after the application of assembly line; （6） Analysis of samples rechecking before and after the application of assembly line .Results （1） Open assembly line costs least on hardware （8 million） and site among various projects;（2） Inspection process is greatly simplified after the application of assembly line;（3） The samples′volume of biochemical and immunoassay inspection were reduced by 31.85％;（4） The items′test cycle decreases after the application of assembly line , the average TAT is reduced by 32 minutes;（5） Staffs for samples pretreatment can be reduced by 50％after the application of assembly line , and the quantity of operators does not change;（6） The number of re-check samples increase except the gray zone and critical values , which ensures the reliability of the results .Conclusion To analyze the core data and to evaluate the performance , the laboratory improve on detection cycle ,staffs,and test efficiency.
