Heads up. There's a new abbreviation in town: IQCP
Can you guess what IQCP means?

Intelligent Quality Control Plan
Incoherent Quality Control Plan
Ill-conceived Quality Control Plan
The answer, after the jump...

Recently, a user submitted a question about the mandatory use of the 10x rule on chemistry analytes as mandated by ISO 15189 through NABL:
"Specific criteria of accreditation of NABL India (for ISO 15189) say that 10x should be considered as a violation for clinical chemistry and Immunoassay parameters. However we understand that Westgard rules consider it as a warning only. Please advise."
So, the central question is, does ISO 15189 mandate the use of the 10x control rule?

So we all know that Risk Analysis is coming to laboratories in the US. (click here if this is news to you). But Risk Analysis, particularly the FMEA technique (Failure Mode and Effects Analysis), is not new to healthcare. Outside the laboratory, plenty of healthcare practitioners have been performing FMEA.
So what do they think about this technique? Try and guess which one of these responses is from a someone in healthcare:
"The jury's still out on the FMEA process because... has anybody evaluated FMEA as a tool for analysing risk? And it turns out there isn't... well why are we doing this process?... When all it is doing is bringing a few things to the surface, which is no bad thing, but it's not a validated process."
"...Forget FMEA. It doesn't really work effectively, I don't think, and the scores are a hindrance rather than anything else, year... We wasted a lot of time on FMEA before we realized, this isn't actually working. Yeah, because I think you can get caught up on just the score, that's the thing."
"The scoring in the FMEA teams need to be the same people, if you change half way through because of the highly subjective interpretation things change dramatically."

In the December 2011 issue of Point of Care journal, an interesting study was published:
Preanalytical Errors in Point-of-Care Testing: Auditing Error of Patient Identification in the Use of Blood Gas Analyzers, Natalie A Smith, David G Housley, Danielle B. Freedman, Point of Care, Volume 10: Number 4, December 2011.
The study looked at patient identification errors on a blood gas analyzer in various departments in a hospital. Bearing in mind that this is just one type of pre-analytical error, what do you think the rate was? Given around 100,000 tests, what would you guess as the number of defects?
