Six Sigma : a breakthrough strategy for evaluating analytical quality in clinical biochemistry laboratory of a tertiary care hospital

Dr. Sayari Banerjee, Dr. Jayati Roy Choudhury

Abstract :

There is no dearth of evidence to show that ensuring quality assurance is presently considered as a basic need in all sectors including laboratory service. In the clinical biochemistry laboratory application of six Sigma rule is a quality management strategy that improves assay quality by identifying biased and imprecise assays.We aimed to evaluate our laboratory performance by using sigma metrics. Internal quality control (QC) data obtained from clinical biochemistry laboratory of College of Medicine and Sagore Dutta Hospital was analyzed retrospectively over a period of 6 months from July 2016 to December 2016 . Sigma factor were calculated for most of the laboratory parameters. Parameters with Sigma values (>6) such as alkaline phosphatase, triglyceride, HDL considered as satisfactory. Parameters such as SGPT and cholesterol with Sigma <3 considered as poor. The findings of our study will emphasize on the need of evaluating ongoing quality assurance programme and adoption of corrective measures in order to implement six sigma standard in Quality Control for all the analytical processes.
