At the AACC/ASCLS conference in San Diego, many of the Sigma VP laboratories contributed to a poster on evaluating the applicability of various analytical performance specifications for AST:
Multisite study of AST analytical performance reveals disparities in global performance specifications
The full poster can be downloaded from our westgard.com download section here. (free membership required)
But what was most rewarding was meeting with many of the co-authors who came to the meeting.

We got the following question emailed to the website recently:
Greetings, I was [wondering] if the following case represents [violation] of 4 1s rule?
Control (A) point 1= EXCEEDS 2 SD /-2 SD lines >> warning
Control (A) point 2= WITHIN 2 SD/-2 SD lines >> accepted
Control (A) point 3= EXCEEDS 2 SD /-2 SD lines >> warning
Control (A) point 4= WITHIN 2 SD/-2 SD lines >> rejection
all the point[s] on the same side of the mean.
What do you think? The answer, after the jump

A recent op-ed in the New York Times by Dr. Robert Wachter as well as an interview with Don Berwick in HealthLeaders Media broached a taboo topic: is healthcare measuring too much?
'[T]he measurement fad has spun out of control. There are so many different hospital ratings that more than 1,600 medical centers can now lay claim to being included on a “top 100,” “honor roll,” grade “A” or “best” hospitals list. Burnout rates for doctors top 50 percent, far higher than other professions. A 2013 study found that the electronic health record was a dominant culprit. Another 2013 study found that emergency room doctors clicked a mouse 4,000 times during a 10-hour shift. The computer systems have become the dark force behind quality measures.'
How Measurement Fails Doctors and Teachers, New York Times, January 16, 2016
As the global debate over establishing the best error models and performance specifications rages, laboratories are probably asking themselves the same questions that the doctors are asking: how many metrics are too much?
A possible answer, or at least some more questions, after the jump...
