I came across a very valuable paper in Clinica Chimica Acta on the stability of hematology controls for MCV. (Some of you are already guessing what this is going to be about...)
If you take a hematology control, how many SDs should you expect to see it shift at week 5 of use versus the first week of use? In other words, what is the SDI you should expect?
- 1 SDI
- 2 SDI
- 3 SDI
- 4 SDI
- 5 SDI
- higher than 5 SDI

Diagnostic errors are one of the "new" hot topics in the healthcare field. A new study from British Medical Journal of Quality and Safety has a chilling estimate of just how common diagnostic errors are occurring in outpatient settings.
So what's your guess? How often in the US are diagnostic errors being made in outpatient settings?
- about 1 in 5 visits
- about 1 in 10 visits
- about 1 in 20 visits
- about 1 in 50 visits
- about 1 in 100 visits
The study's conclusion, after the jump...

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...

While we recently got a study that estimated the (frightenly high) number of Adverse Events caused by US hospitals, it looks like other countries are not content to let us stand alone. Now Sweden is doing us one better. Guess what the Adverse Event rate is in one hospital in Sweden?
- 28.2%
- 20.5%
- 6.3%
- 3.32%
Which number would you choose?

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

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%

It's almost mandatory that any presentation or report discussing patient safety references the landmark IOM report of 2000: To Err is Human - Building a Safer Health System. The takeaway quote from this report is that US hospitals were causing 44,000 to 98,000 deaths that were otherwise preventable. That is, hospitals were causing tens of thousands of avoidable deaths.
A recent paper has attempted to revise that estimate, focusing on Preventable Adverse Events (PAEs) that contributed to the death of patients. Can you guess how lethal US hospitals are now?
- 4,000 to 10,000 PAEs per year
- 44,000 to 98,0000 PAEs per year
- 100,000 to 200,000 PAEs per year
- 210,000 to 440,000 PAEs per year
