Abstract:
Objective To establish quality improvement project through theσ value and quality goal index ,then determine the effect of quality improvement by comparing the changes of uncertainty ,provide the laboratory basis for the effective improving of the quality of clinical laboratory .Methods The quality control data of blood cell analysis items were analyzed ,and the σ values , quality goal index (GQI) and measurement uncertainty [u(Rw)] were calculated and the performance was estimated .The quality improvement project was designed and had run for one year .The effect of quality improvement project was determined according to u(Rw) changes .Results The excellent rate (σvalue >4σ) of process performance evaluation in 2012 was up to 62 .5% ,the items withσvalue>6σamounted to 37 .5% ,about 62 .5% of the items needed to be improved .Comparing the u(Rw) in 2013 with 2012 , the improvement rate was 50% .The laboratory quality had been improved .Conclusion The performance analysis of σvalue ,GQI combined uncertainty evaluation is a good management method to improve the efficiency and reduce the cost .
