Risk management is a paradigm shift from statistical quality control. Statistical quality control, Levey-Jennings charts and Westgard Rules are designed to detect CHANGES in analytical accuracy or precision. It’s up to lab staff, with little education or practice, to decide if that change is for the better, for the worse, acceptable or unacceptable. Most of us were taught that “Where you are now is Good” and “All change is Bad.” People think they can judge bias on a QC chart, even though they know that bias compares the current mean relative to the True value, and the QC chart does not show the True value. Here’s the uncomfortable truth: Statistical QC is designed to detect change—not to tell you if that change matters. A new reagent lot shifts your mean. The rules alert you. But you’re left guessing whether you’re still flying safely or heading straight into a storm.
This is where Risk Management becomes a paradigm shift.
The Risk Evaluation Chart in RiskGATOR™ doesn’t just show you that something changed. It plots your QC data against the True value and your TEa limits. It shows you if your method is still acceptable—or if you’ve drifted into dangerous territory.
Think of it like a flight simulator. Fly too high, you hit the storm. Fly too low, you hit the trees. Lab staff never get to see if their QC processes actually keep patients safe. They’re flying blind, reacting to alarms without knowing if they’re still in the safe zone. Now you can see it. Each airplane in the image represents a different reagent lot. The existing lots were acceptable, but if you were to shift to the red plane, risk becomes unacceptable. If this is a new reagent lot, do not use it. With RiskGATOR, you don’t just detect change—you evaluate risk. You define acceptable performance as the acceptable number of medically incorrect results during stable operation, and if a method fails unexpectedly. Acceptable risk is not some abstract sigma metric from 40 years ago. If you’re ready to stop flying blind and start managing risk with clarity, plan to attend a MasterClass on Risk Management with global speakers on March 24th and 25th. You’ll work with a live simulator to explore real-world scenarios and discover what it feels like to truly understand your lab’s risk profile. You finally get to see if you’re keeping patients safe.
