I think that no matter where you go, there are probems (especially hemolysis) from ED-drawn samples. From the few facilites that I have worked at over the years, I have noticed this to be true.
A few months before I departed one facility, we started tracking all sorts of variables from ED samples - mislabeled, unlableled, hemolysis, short draws, contamination (drawn above IV, from medicated port, from heparinized port), more than one patient in a bag, etc. I know that our one lab supv was a stickler for proper specimen integrity and would go to bat for us whenever a situation arose.
They started to work on getting proper phlebotomy education out to them as well as the rest of the nursing floors, as they were all soon going to become responsible for a lot of their blood draws. Were we going to be able to eradicate IV cathetar draws? No. Could we bring it to light for them that it could only increase turn around time by taking this common short cut, hopefully so.
I, unfortunately, don't know the end result of this study, however, I do know that that tabulation sheet was often full by the end of the day.
