Pilot program explores RFID's role in blood transfusion safety

San Fernando, Calif. — Precision Dynamics Corporation (PDC) and Georgetown University Hospital's (GUH's) Blood Bank will conduct a pilot study to explore how Radio Frequency Identification (RFID) wristband solutions increase the efficiency and reliability of blood transfusion safety. PDC's Smart Band RFID Wristband System will be used in the study.

For more than two years, GUH's Outpatient Infusion Service has used PDC bar code solutions as standard practice for double checking and verifying blood transfusions. Today, GUH is interested in learning whether RFID solutions can increase the efficiency and reliability of transfusion safety in instances where bar code ID isn't as effective.

"Bar code identification solutions are very valuable to institutions like GUH," said Dr. S. Gerald Sandler, director of Transfusion Medicine at Georgetown University Hospital. "However, RFID technology offers the promise of improving the efficiency and reliability of conventional double checks for matching blood transfusions with the correct patient."

To ensure positive patient identification, PDC's Smart Band acts as a portable, dynamic database that carries patient information to be used and updated during a patient's stay. Smart Band's accurate, automated system ensures the integrity of information between patient, host device, and/or hospital information system. Unlike bar code, RFID's non-line-of-site data transmission can be read through and around the human body, clothing, bed coverings and non-metallic materials.

"We expect this study to show that RFID solutions complement bar code technologies and increase the efficiency and reliability of identifying patients, their blood samples and their intended blood for transfusion," adds Dr. Sandler.

PDC's Smart Band contains an embedded Texas Instruments' Tag-It RFID chip. PDC RFID labels will be printed and RFID chips encoded using an R402 RFID printer encoder from Zebra Technologies. AMTSystems PatientSafe Transfuse RFID and Transfuse ID transfusion software system will also be used in the study.

The initial phase of the study, which consists of laboratory reviews and validation of the equipment began on March 1. The research phase and clinical implementation will begin two to three weeks after completion of the initial phase. The study will evaluate and compare the effectiveness and efficiency of bar code ID and RFID solutions during blood transfusions of 100 patients. A key research instrument will consist of evaluations by nurses using both technologies.

The study has been reviewed and approved by GUH's Institutional Research Board. For further information on the study or on PDC RFID solutions, visit www.pdc-rfid.com.
