We have pre-determined Doe names -- we go down the phonetic alphabet with a different number as the "middle" name each time through the list, i.e., Doe, Alpha 35; Doe, Bravo 35; etc. As a level II trauma center, we have 2 levels of traumas -- full and partial. We usually have a name with the partial traumas, but the full traumas are assigned the Doe names and are given a new Medical Record #. The admissions dept. quickly registers the patient when word arrives that the patient is coming in. We use the Mobilab system, so the armband label is placed on the patient and labels made by scanning the armband are placed on the specimens -- so we have the two identifiers that are needed. When the real patient ID is made, admissions puts in the name but leaves the Doe name in parantheses on the armband and other patient ID. The new MR# given stays with the patient at least as long as that initial blood bank specimen is valid (72+ hours to midnight). At that time, if there was a pre-existing MR# for the patient, the accounts are merged.
When uncrossmatched units are issued, we place them in a cooler and write the unit information on a cooler log sheet. Since this is an extension of our blood storage refrigerator, the nurses sign the unit out of the cooler using the log sheet. We have patient ID information on the log sheet, but we do not go over all of the unit information at the time the cooler is issued.
We use Meditech in our facility, and Barcode-enabled Transfusion Administration (BCTA) is used -- so one nurse can check the unit with the patient when using the computer for the other nurse. We also use Electronic Crossmatch that makes our lives much easier.
This system works very well for us.
