Objective To investigate the effect of six Sigma management in clinical biochemical specimens.Methods The unqualified specimens in the biochemical laboratory of Guihang Guiyang Hospita from January 2019 to December 2020 were selected as before management,and the unqualified specimens from January 2021 to December 2022 after the implementation of six Sigma management mode were selected as after management.The unqualified specimens were analyzed before and after management.Results The unqualified rate of biochemical laboratory specimens from January 2019 to December 2022 was 0.61‰,and the unqualified rate from January 2019 to December 2020 specimens was 0.98‰,and the unqualified rate from January 2021 to December 2022 was 0.26‰,the difference was statistically significant(P<0.01).The unqualified specimens were most common in pediatrics(14.98%),cardiovascular medicine(9.39%),respiratory and critical care medicine(8.48%)and endocrinology(8.12%).Hemolysis(24.01%),agglutination(20.76%)and unqualified labeling(20.22%)were the most important reasons of unqualified biochemical laboratory specimens.Conclusion The application of six Sigma management method can effectively reduce the incidence of unqualified specimens in clinical biochemical testing,and help to improve the quality level of clinical laboratory biochemical testingy.
