Any facilities out there using the Mixing method (Push pull method) for lab draws? What are you opinions? Does anyone know where the "Sacred Cow" of a 10mL waste from a central line came from?

It may have come from a study but I know that study would have to be more than 10 years old by now. There are other studies now. See INS SOP 2016 Phlebotomy for info up to 2015. Push-pull or the mixing method is supported by good research and an acceptable method for drawing samples from a catheter, also addressed in INS SOP.

I am working on a QI project with a coworker to implement this practice starting in our ICU. Having run it by our Nursing Research Council they want to bring it up to the IRB. It may turn in to a research project for us.
I am familiar with the research and recent literature primarily in the pediatric oncology and critical care popualtions. We want to implement it the adult critical care population.
Lynn, do you know where the "sacred cow" blood waste method was first research and published? Trying to find that to better understand the background.

There have been several studies on the discard method, assessing accuracy of lab values after discarding various amounts of blood. Discard method was the original way but I cannot point you to the first studies. You should be able to find those with a lit search. Also, there is literature associating hospital acquired anemia with excessive blood draws and wasting of blood, a major reason to use the mixing or push-pull method.
