Sigma Metric Analysis
Now that we know how to translate the manufacturer's performance claims into Six Sigma metrics, let's take a hard look at some real-world data. With a performance study supplied by a "near-patient" chemistry anlayzer, we find out just how good (and how bad) performance of tests are when they're at the POC.
Continuing in our series on translating method validation studies into Six Sigma metrics, we examine a Roche Integra 400+ chemistry analyzer, with data provided by St. Joseph Hospital in Houston, Texas.
Working with CAP Today's recent survey of High Volume Hematology Analyzers, we convert the manufacturer precision claims into Six Sigma estimates. Want to see how the instruments shape up?
Are things better or worse in hematology than in chemistry? Data from a recent AACC conference poster reveals more good news...
A poster from the 2005 AACC convention provides us with a great set of data on CV and bias for a new chemistry instrument. From that data, we can evaluate the Sigma performance and the QC required by the instrument. We can even compare the new instrument with Sigma metrics from other competing instruments.
