A random, unique, four-letter code (printed on a self-sticking label) is affixed to a patient's hospital wrist band at the time of admission or specimen collection for pretransfusion testing. For pre-admission testing, the coded label will be included in the admission packet and will be affixed to the patient's wrist band at the time that band is placed on the patient.
The four-letter code is transcribed to the pretransfusion specimen tube label when the specimen is collected. The phlebotomist will underline the code to identify it from other information on the specimen label.
When blood components are to be issued for the patient, the units will be placed into a clear plastic bag, a blood lock device set for the patient's unique, four-letter code will be used to "lock" the bag, and the lock will be scrambled. The lock will only open with the code attached to the intended recipient's wrist band.
The Transfusionist will dial in the code found on the patient's wrist band to open the lock. On removing the blood component(s), the Transfusionist will insure positive identification between patient, blood component and Record of Transfusion Form as is current policy. Refer to the Transfusion Committee Policy, Blood Component Administration, for complete procedural information. Should the lock fail to open when the patient code is dialed in.....
S T O P! Contact the Blood Bank, (5-7207), to investigate the cause for the lock not opening. Transfusion of the component(s) should not be initiated until resolution of this disparity is resolved and positive identification of the patient and the correct blood component(s) is made.
