We instituted a second sample at the time of RBC request in patients whose first (and only) type in our system is not O. The second sample is collected with a fingerstick collection device with EDTA, in order for us to be sure we are getting an actual second sample. The ER will double draw every time, and if a mistake is made, it's just duplicated. We send a "packet" including the device, an alcohol prep pad, sterile gauze packet, bandage, and complete INSTRUCTIONS on how to collect & label. A quick ABO/Rh confirmation is done on this, if all is OK, the crossmatched blood is released. Predictably, the only area from which we have had any pushback with this was the area that caused the protocol to be put in place in the first place, the ER. :mad: (We had 2 ABO mistransfusions due to WBIT samples from the ER in the space of 24 hours, a couple of year). Fine, you don't want to give us a fingerstick sample, we'll supply type O blood and ask the OR to do it for you! I have had to encourage the creativity of the anesthesiologists on where to obtain "fingerstick" samples when fingers may not be available. Earlobe, shoulder, upper arm, etc, are all fine. In the 2 1/2 years we have had the protocol in place, we have "caught" at least 6 wrong types where patients initially typed non-O were actually O. So it still happens. I would love to be sure that everyone drawing blood was trained to do it the right way, every time. But the lab in our facility no longer has jurisdiction over phlebotomy, and there are too darned many people, who turn over too often, doing blood draws for this to be practical. We have not seen a great deal of "excess" type O use waiting for fingerstick samples. The blood bank leadership enforces the policy with applicable department heads, as needed. We will never withhold blood from any patient for the lack of a fingerstick, type O is always available. Once the applicable staff get this thru their heads, we see no trouble with compliance. I try to regularly reinforce good inventory management with appropriate areas.
