The Myths of Quality

We like to assume that everything works perfectly in today's healthcare laboratory; that analytical quality is a given; that even if we don't know what quality we need to achieve, we're achieving it; that today's methods have better imprecision and inaccuracy than needed; that no further improvements are necessary in the QC of the 21st century. Dr. Westgard discusses these myths, sorting fact from fiction, and providing commentaries. Read this essay Back to Top

Putting Quality into Quality Control

Many laboratories and manufacturers say that they "do" quality control - but can't explain what level of quality they're acheiving. The term "Quality Control" is much-abused. In many cases, Dr. Westgard explains that what laboratories are actually performing is arbitrary control, not quality control. How do we put the quality back into quality control? Reading this essay is a good start. Read this essay Back to Top

Assuring Quality through Total Quality Management (TQM)

The teachings of industrial quality gurus, such as Deming and Juran, established new principles and processes for managing quality. Deming provided the principles for what needs to be done and Juran described the methodologies or processes for getting it done. See how a combination of these two - Total Quality Management (TQM) - can be applied to the healthcare laboratory field. Read this essay Back to Top

Trends in Quality management: Utilization and Outcomes

Re-engineering, out-sourcing, down-sizing, outcomes focus -- all the management fads have come to the healthcare laboratory with a vengeance. Dr. Westgard (with a little help from Dilbert) sorts out which approaches are valid and which are dangerous. Read this essay Back to Top

Quality Goals, Requirements, and Specifications

Everyone agrees that there should be quality control. But what does that mean? When we implement new methods in our laboratories, or develop new methods, or try to establish regulatory guidelines for performance of methods, or even inspect laboratories to assure that good quality management practices have been implemented, how do we specify bias, CV, the number of controls, the levels, etc.? Dr. Westgard introduces a way to sort it all out. Read this essay Back to Top

Future directions in Quality Control

Total Laboratory Automation and POC devices are two trends in current diagnostic equipment. Dr. Westgard reviews the history of quality control, from manual methodsin the 1950s, to the current state of the art of laboratory fourth generation instrumentation, to the quality control systems in future instruments. Learn how automation and computerization will impact the future quality control practices - what will be done for us, and what we still have to do for ourselves. Read this essay Back to Top

The Myth of Medical Decision Limits

Medical Decision Limits are described as a "second set of limits set for control values ...meant to be a wider set of limits indicating the range of medically acceptable results." The idea is that these medical decision limits embody the medical usefulness requirement for a test and by drawing these limits on our control charts, we will detect medically significant errors. Using CLIA QC requirements and practical examples, Dr. Westgard evaluates these MDLs and reveals their true nature. Read this essay Back to Top

Quality by Design

An updated version of this essay appears on the Nothing but the Truth about Quality book. If we're honest with ourselves, we know that the situation in the laboratory needs to be improved. But with all the time pressures, staff shortages, and other stresses, how can we find a quick way to put the quality back into quality control? How do we select methods that can guarantee error detection? Create purchase specifications to select instruments that can guarantee we meet our CLIA requirements? Design instruments with quality in mind? Dr. Westgard suggests practical steps that both users and manufacturers can take to bring quality into their design. Read this essay Back to Top

Tools and Technology for QC Planning

Just as instruments have evolved from manual pipettes to vast automated instruments, so too has the technology for quality control. When we're using a fourth generation instrument, should be be doing first generation quality control (like the old standby, 1:2s), a practice that was introduced in the 1950's? Dr. Westgard charts the history and progress of QC technology and introduces new tools (QC Selection grids, OPSpecs charts, automated QC selection) that we can use for the 21st century. Read this essay Back to Top

Education and Training in Analytical Quality Management, Part I: Developing a Lesson-Base

The Digital Age has revolutionized countless facets of our society. Dr. Westgard discusses how the Internet it has and will impact our industry: how we can now access education and training over the web at anytime, from anywhere in the world. (If you can read this, you're part of the revolution!). Read this essay to see how workshops, courses, seminars and more will be affected by electronic communication. Read this essay Back to Top

Mapping the Road to Analytical Quality with Charts of Operating Specifications

Quality is often described as a journey. Too often our efforts describe where we've been and how we arrived at the present, rather than advancing to where we need to be in the future. Laboratory efforts need to advance quality with well-defined destinations, maps to guide us to those destinations, and careful planning to provide a smooth journey. The way is revealed. Read this essay Back to Top

Method Validation: The Inner, Hidden, Deeper, Secret Meaning

We run controls, we collect data, we create graphs and charts and plots and crunch numbers. Then we stuff it all in a folder and hand it to an inspector. It's called method validation. But what is it? How do we do it? Why do we do it? Dr. Westgard reveals the secret meaning behind it all. Read this essay Back to Top

Principles of QC Planning for Immunoassays

Dr. Westgard takes the theory and tools of quality planning and applies it to immunoassays. This was part of his presentation to the joint meeting of UK National External Quality Assessment Schemes (UK NEQAS) for Endocrinology and the European Ligand Assay Society (ELAS) in Edinburgh, Scotland, a paper that he delivered "virtually" to the conference. Read this essay Back to Top

Education and Training for Analytical Quality Management, Part III: Basic QC Practices training

Over the years, the practice of quality control has been corrupted (all those repeat runs, widening control limits, and even worse). It's time to get back to the basics. To that end, using all the technology of the late 20th and early 21st century, Dr. Westgard introduces a Basic QC Practices training course available online, on CD, and in one of those "old-fashioned" books. (If you ask nicely, he'll probably do it in person at your next conference, too.) Read this essay Back to Top

Electronic QC and the Total Testing Process

An updated version of this essay appears on the Nothing but the Truth about Quality book. POC devices are all the rage. But they don't do normal QC, they do "electronic QC".

When will we realize that higher management has a problem with quality? Read this essay Back to Top

Errors in Reasoning about Laboratory Errors

An updated version of this essay appears on the Nothing but the Truth about Quality book. What's scarier? The fact that there are errors in laboratories, or the fact that we don't understand what those errors mean? A lot of logically dubious arguments have been put forward about reducing QC, ignoring QC, or eliminating the practice of QC altogether. Dr. Westgard examines and refutes the thinking behind these arguments. Read this essay Back to Top

Six Sigma Quality Management

Have you heard about Six-Sigma yet? It's the latest trend in quality management. It has revolutionized business processes in companies like GE and Motorola.

We have enough rules to go on right now - and here's how to use them to improve QC... Read this essay Back to Top

Repeated, repeated, got lucky!

An updated version of this essay appears on the Nothing but the Truth about Quality book. Believe it or not, but this is an actual comment from an QC action log (from a facility that shall remain nameless). At least the author was being honest about how he/she was performing their QC - by luck, not by science. If you still use 2s limits for your controls, you need to read this article. If you still repeat controls and runs until they're "in," you need to read this article. And for anyone who thinks that QC is just fine, you really, really need to read this article.

More on CLIA and "Quality-Less Compliance"

An updated version of this essay appears on the Nothing but the Truth about Quality book. We've posted a large number of articles about the specifics of the Final CLIA Rule and the accompanying Interpretive Guidelines. But in addition to covering the specifics, we need to look at the big picture. Why did we get the CLIA Final Rule and Interpretive Guidelines the way that we did? Why did it take over ten years to complete? Why did manufacturer's QC clearance go by the wayside? How did we end up with "electronic QC" and "equivalent QC"? Read this essay Back to Top

Testing Equivalent Quality: A Better Way

An updated version of this essay appears on the Nothing but the Truth about Quality book. CMS has created "equivalent QC", but the regulations really only allow "equivalent quality testing." This difference is important - and if "Eqc" is here to stay, finding the equivalent quality in testing is the only way to find a real solution. Finding that quality can be done, and done simply, using Sigma Metrics. Read this essay Back to Top
