Positive Patient and Sample Identification for Blood Radiolabeling Procedures with a Bar Code System

Abstract

Objective: Three patients have been reported to have received blood or a blood product from another patient infected with the human immunodeficiency virus (HIV) while undergoing nuclear medicine procedures. We have developed a personal computer-based bar code verification system for accurately identifying blood samples used during the leukocyte radiolabeling process.

Methods: The system involves production of a bar code label for each syringe and tube used in the cell labeling process. At the time of blood withdrawal, the patient is issued a wristband containing a bar code label. During the radiolabeling procedure, the labels on the tubes are scanned to match the label on the blood-withdrawal syringe. Upon the patient’s return for reinjection, the bar codes are again scanned to verify the patient on the syringe and wristband match. Patient identification is also confirmed verbally and by comparing signatures obtained from the patient.

Results: It was anticipated that this verification procedure would be very time consuming and laborious. The patients have voiced their appreciation for the efforts we have taken to ensure their safety. The positive response from our patients has resulted in greater acceptance by the technologists working with the new system. The true value of this system is measured by the accuracy of patient identification and by the confidence that patients have in our work.

Conclusion: The implementation of a bar code verification system has enabled us to minimize the risk of patients receiving the wrong labeled cells without involving more personnel to perform identification procedures.
