RFID and Transfusion international:

2003 - donation till hospital depot (passive)

first trials with Temp Sense (semiactive)

(DRK-BDS Sachsen, Dresden)

2005 - patient identification by drug- and blood-

application (Siemens � New York and Saarbrücken)

- patient identification by drug- and blood-

application (Boston)

- temperature control by hospital transports

(Innsbruck, Vienna with Temp Sense)

2006 - transponder hospital depot till patient (Washington)

- ROI and influence on blood (Milwaukee)

2007 - temperature control until transport with Vario Sens

(DRK-BDS East, Dresden)

� founded at July 1th 2005 in Athena

� invitation, aim and topics in 2005, 48 participants

ISBT - WPIT Task Force “RFID”

� creation of two websites

a) for internal use (BSCW-server)

b) for official use (www.rfid-transfusion.org)

� 5 meetings till 2006

� planned for 2008 June: final draft of a guideline for

the use of RFID Devices in Transfusion Medicine

3

� technical overview and comparison with other Auto-ID’s

� risk assessment

“RFID”-guideline: main topics

� current usages in industry and health care

� possible improvements in health care and

transfusion medicine

� implementation in transfusion medicine:

- standardization

- technical architecture

- implementation methodology

- validation tips

- frequency by direct contact: 13.56 MHz

- documentation and logistic processes faster and easier

- can improve transfusion safety

agreements

- the points of first implementation (pain points) are

different in several blood banks

- usage of ISO 15693 tag, switch to new HF item tag

when it’s available

- buy readers with guaranteed future upgrade capability

production of ~80%

in 16 DRK-institutes

(70.000 – 750.000)

Red Cross Blood Donation Services in Germany

advantages in transfusion medicine

- easier documentation (non direct/ bulk reading)

- easier localisation (allow identification of “best” product by PC)

- saving of relevant data on blood bag (read/ write tags)

- temperature control (semiactive tags)

5

Questions

- tag survive harsh environment (e.g. 5.000xg centrifugation)?

- blood “fluid” � readable?

- influence of frequencies on blood cells and proteins?

- what tag capacity, functionality and safety?

- implementation in supply chain reasonable

- cost versus benefits?

our dream:

quick bulk reading with

robust, multifunctional

and cheap RFID-tags!

centrifugation

- correct packaging,

- sticking after separation

(passive label on plasma bag can be used for

RFID-identification of whole blood system)

buckling of labels

Only with reorganisation of the entire process it would be

possible to increase patient safety and to find an ROI!

The reorganisation of the health care system started already

and its on ourselves to create the processes not only under

monetary aspects…

Blood is a good single example for all drugs!

RFID as barcode replacement is very expensive!

Conclusions

“Safer blood for Pakistan”

(Febr. 2007)

because it would be possible to do anything cheaper!
