For our outpatients who require transfusion, we use a Typenex band, so the patient's name, DOB and band number. When they are transfused, they must have that band on but then the nurses use the FIN to scan along with the barcodes on the unit. We have Meditech and use TAR.
For inpatients, we use the hospital wristband, no separate BB band. The FIN (financial number) is what the nurses scan when they are transfusing a unit. We use the MRN when we check history.
