Résumé

Objective To evaluate and improve overall quality detection of 8 instruments in emergency laboratory using 6σ quality standard.Methods In 2017,collected both internal quality control (IQC) and external quality assessment (EQA) data of 46 assay items from 8 instruments in their laboratory,and then calculated their σ values and total allowed errors ac cording to CLIA'88 standards.By comparison of their quality goal index (QGI) between first and second half year of 2017,successfully elevated assayquality using strategy (man,machine,material,method,measurment and enviroment).Results For all 46 assay items (except NT-proBNP without second EQA data),made better improvement of detection of 34 (75.6 % of 6σ qualified),38(84.4% of 5σ qualified),40(88.9% of 4σ qualified),44 (97.8% of 3σ qualified) and 1 (2.2% of 2~3σ qualified) items,respectively whereas there were 27 (58.7% of 6σ qualified),30 (65.2% of 5σ qualified),35 (76.1% of 4σ qualified),41 (89.1% of 3σ qualified) and 5 (10.9% of 2~3σ qualified) items before improvement.Conclusion Using 6σ quality standard,could make more progress in the laboratory for many respects:fast and accurate clinical reports,reducing reinspection rate,and increasing patient's satisfactory,etc.
