“…Bill Smith,known as the father of Six Sigma, decided tomeasure the defects per million (DPM) instead of defectsper thousand. The number of errors, or DPM, is a measureof laboratory performance 10 .The measurement of quality on asigma scale in the preanalytical phase requires monitoringof outcome process, counting the defects, calculatingthe DPM and using statistical tables to convert the DPMinto sigma metrics 11. The sigma value indicates the frequency of errorsin a process.…”

(QI-8), 0.9% (19/2012) were (QI-9), 12.9 %( 261/2012) were (QI-10) and 84% (1701/2012) were When these results were compared with specifications of IFCC (WG-LEPS), and QI 10 were found to be within optimal level whereas QI-12 was within desirable range. Sigma value for , , and QIs were 5.0,5.2, 4.5 and 3.8respectively. Conclusion:The preanalytical performance of our laboratoryis favorable and complies with international qualityspecifications.

“…A process rating at a level of “six sigma” (also indicated as “world class quality”) is expected to miss suitability with a probability of 0.00034% (about 1 every 300,000 tries), even considering a 1.5 sigma drift from its target output (Table 1) ( 9 ). …”

Almost thirty years of systematic analysis have proven the turnaround time to be a fundamental dimension for the clinical laboratory. Several indicators are to date available to assess and report quality with respect to timeliness, but they sometimes lack the communicative immediacy and accuracy. The six sigma is a paradigm developed within the industrial domain for assessing quality and addressing goal and issues. The sigma level computed through the Z-score method is a simple and straightforward tool which delivers quality by a universal dimensionless scale and allows to handle non-normal data. Herein we report our preliminary experience in using the sigma level to assess the change in urgent (STAT) test turnaround time due to the implementation of total automation. We found that the Z-score method is a valuable and easy to use method for assessing and communicating the quality level of laboratory timeliness, providing a good correspondence with the actual change in efficiency which was retrospectively observed.

“…Another method to assess Preanalytical performance quality is the Six Sigma methodology developed by Motorola, Inc. 7 Using six sigma metrics, number of errors can be expressed by counting defects per million (DPM). Then, using statistical tables, DPM can be converted to sigma metrics.…”
