Redcliffe Labs,a diagnostic provider has achieved a significant enhancement in lab quality processes by incorporating Six Sigma metrics, according to a study led by Dr Sohini Sengupta, the Medical Laboratory Director at Redcliffe Labs, the company said in a press statement on Tuesday. The strategic implementation of Six Sigma resulted in fewer errors, reduced sample reruns, and improved turnaround times, ultimately reinforcing clinician trust and patient satisfaction, the statement from the company informed.
Conducting a two-phase quality improvement project, Redcliffe Labs, under the leadership of Dr Sohini Sengupta, assessed and optimised testing processes across 25 routine high-volume assay parameters. This comprehensive evaluation included 20 clinical chemistry and 5 immunoassay methods, with a focus on identifying and addressing parameters with lower sigma scores in the pre-period.
Implemented over a rigorous 6-month timeframe, the strategic measures showcased tangible results in the post-period analysis. The average sigma metric surged impressively from 6.4σ to 9.2σ, indicating a substantial improvement in the laboratory's performance. Out of the 25 analytes studied, 17 exhibited noteworthy enhancements, surpassing the pre-defined threshold of a 1.0 increase in their sigma metric.
The most remarkable improvement was observed in Glucose, a commonly tested parameter, which surged from 3.9σ to an exceptional 26.3σ. This surge directly translated into a significant reduction in the error rate, improving reliability from 9,224 Defects Per Million Opportunities (DPMO) to less than 1 DPMO.
Dr Sohini Sengupta emphasised, "The impact of our quality improvement study extends far beyond metrics—it's a testament to our commitment to excellence. Achieving world-class performance across high-volume assays by adopting Sigma metrics elevates our confidence in our test results. It reiterates our continued focus on achieving the highest standards of quality at Redcliffe. These enhancements also mean fewer errors, efficient workflows, and faster turnaround times."
