Application of questionnaire survey and 6 sigma quality management methods in improving the quality of routine blood tests

Objective To continuously improve the quality of routine blood tests through questionnaire surveys and 6 sigma(σ)quality management methods,to effectively improve the level of unit laboratory testing,and to ensure the quality of testing.Methods A questionnaire survey method was used to investigate the current status of laboratory quality management such as system documents and quality indicators of 11 units participating in the project research.According to the problems existing in the first investigation,targeted training was carried out,and the rectification effect was verified in time.After a lapse of 2 years,the above-mentioned units were surveyed again,and the results of the two questionnaires were compared and analyzed,including total allowable error,coefficient of variation(CV),deviation(Bias),σ,and quality target index(QGI).Results Through the promotion of this project,the participating units gradually improved the quality system documents;standardized the blood routine performance verification of the participating units.The excellent rate of analytical performanceσvalue(σ≥4)of 11 hospitals from 77.04%in 2016 to 88.00%in 2018,the growth rate was 14.23%.The proportion of participating in the quality assessment of the national health commission′s interim inspection center increased from 90.90%in 2016 to 100.00%in 2018.The participation in the quality assessment of the provincial(city)interim inspection center increased from 81.82%in 2016 to 90.91%in 2018.The number of relevant in-hospital quality training increased from 162 in 2016 to 322 in 2018,an increase of 98.77%.Conclusion Through questionnaire survey combined with 6 sigma quality management methods to carry out blood routine test quality improvement activities,the level of participating units′laboratories can be raised,and blood routine quality indicators can meet clinical needs.
