A recent article about the experience of QMS tracking in a clinical laboratory in Nigeria raised some interesting questions about sources of errors in "developing world" laboratories.
Where would you expect a Nigerian Human Virology laboratory (HVL) to experience the most problems?
- pre-analytical processes
- analytical processes
- post-analytical processes

Earlier this month (July) I came across a series of revealing posts on a listserv about the quality of glucose meters. For me, it raised the question, just what defect rate is acceptable at the point of care?
- 0.00034%
- 1%
- 5%
- 10%
- 40%
- 75%
- 100%
What level of defect rate do you believe is being seen at the point of care? the answer (after the jump) might astonish you...

Two interesting abstracts and papers concerning HbA1c came out recently. As laboratories switch from fasting blood glucose to HbA1c to diagnosis diabetes, the importance of the method performance of HbA1c methods is becoming critical.
But what's more important? Bias or CV?

As many of you know, EQC is out and IQCP is in. As the expiration date for EQC approaches in 2016, labs need to learn more ab
out Risk QC and IQCPs. CMS has an email address where you can send questions.
We tried out the question and answer line with CMS, see the results after the jump...

During my travels, I came across this at a laboratory which shall remain anonymous, where they are required by ISO 15189 to report measurement uncertainty to their clinicians:
If you can't read that interpretive comment, I'll spell it out after the jump...

Take the "Low QC" Quiz to see if your laboratory is suffering from this new condition...
- Do you have a decrease in your desire to QC?
- Do you have a general lack of energy at work caused by QC?
- Have you noticed a decrease in your enjoyment of life, possibly due to QC?
- Are you sad and/or grumpy about QC?
- Has there been a recent deterioration in your ability to trouble-shoot QC?

We've all heard the infamous quote now over a decade and a half old: that US hospitals kill between roughly 40,000 and 90,000 patients each year. This was an estimate courtesy of the Institute of Medicine report "To Err Is Human" which made the dire performance of hospitals knowledge that even the general public could understand.
But more recently, studies have been tracking the adverse event rates much more closely. A recent NEJM paper followed four conditions from 2005 to 2011.
Of these four conditions, which do you think has the best Sigma performance when it comes to the occurrence of adverse events?
A. Acute Myocardial Infarction (AMI)
B. Congestive Heart Failure
C. Pneumonia
D. (other) Conditions Requiring Surgery

On August 16th of this year, CMS issued a new memo about IQCPs. If you recall, IQCP stands for Individualized Quality Control Plan, and it's part of the new Risk QC being proposed by CMS as a replacement for EQC. The CLSI guideline EP23, which came out about two years ago, laid out the broad outlines of this new policy, but we have been waiting for the government regulations to spell out the specifics of implementation and interpretation.

In a recent issue of CCLM, an interesting opinion paper reported on a pilot study of the quality of UK laboratories.
Given 5,812 QC data points on 5 different platforms in 9 different laboratories measured over 6 months, and a quality goal of 7.0% how many of those laboratories do you think achieved 5-Sigma quality?
- 100%
- 75%
- 50%
- 25%
- less than 25%
