Error Auditing Procedures

Inspired by a blog from the Westgard website, http://james.westgard.com/the_westgard_rules/2012/01/more-error-rates-at-poc.html, I pulled the original study and as I'm reading through it, I have a question or two and I'm wondering if anyone else does. As I'm reading the original study, (which I would be glad to send a copy to anyone interested in studying with me) the first question I have is regarding operator bias. It states the technicians were aware they were being audited. Does this naturally effect the psyche of the operator who is being audited? Does it force the operator to take more time and care when running a sample when it is known their work is being audited at that time? Were department managers inclined to designate more experienced personnel to handle these samples for testing? I'm still reading through the study, and as I'm reading I was curious to see if anyone else is interested in putting their two cents in on this conversation regarding pre-analytical errors. Let me know! Lab Rat Rebellion is all about bench tech and MLT student feedback.
