SIX SIGMA APPLICATION IN EVALUATING THE EFFICACY OF SOME BIOCHEMICAL TESTS AT QUANG NINH TRADITIONAL MEDICINE HOSPITAL IN 2021

Abstract

In the quality control of the testing process, the Six Sigma method is being implemented to minimize errors to the lowest level. Objectives to evaluate the efficacy of 7 biochemical tests (Glucose, Cholesterol, Triglyceride, Urea, Creatinine, AST, ALT) performed on a Beckman Coulter AU480 using Six Sigma in the Testing Department - Quang Ninh Traditional Medicine Hospital in 2021. A cross-sectional descriptive study was conducted on subjects including 496 internal quality control results at 2 levels of concentration (normal and high) and 12 external quality control results over 12 months in 2021. Calculate the Sigma value with an allowable total error value TEa. Results is at normal concentrations, 5 tests (Glucose, Creatinine, AST, Cholesterol, Urea) had Sigma scores lower than 3, 1 test (ALT) had Sigma scores between 3-4, and 1 test (Triglyceride) had a Sigma score greater than 6. At high concentrations, 6 tests (Glucose, Creatinine, AST, ALT, Cholesterol, Urea) had Sigma scores lower than 3, and 1 test (Triglyceride) had a Sigma score greater than 6. The analysis results show that at both concentration levels, the percentage of parameters within the unaccepted Sigma range was high, therefore quality control measures need to be taken to improve the efficiency of the tests.
