ISBT and RFID task force

Transcription

1 ISBT and RFID task force Impressive at the first look, but horrible in the forest OA Dr. Ralf Knels German Red Cross BDS East Function Access control Bulk reading Counterfeit protection Data storage and transport Identification Localisation Observation Process management Sensory functions Theft protection Time registration Description better acceptance, contactless identification in sterile environments or for work automatic doors incoming, in process and distribution control of hospital wears, pharmaceuticals, blood, surgical instruments, etc. pharmaceuticals, plasma products, instruments, devices mobile data collection/ transport possible in environments without wireless solutions/ server connectivity or for quicker recording in future: data store and carrier for implanted biochips? save patient, sample or application box identification Finding of mobile devices, special blood, staff Mental confused patients, maintenance, sterilisation Emergency supply (processes in time), patient guidance, container guidance for food, wear, pharmaceuticals etc. Temperature, in future: blood pressure, O 2, etc. Babies, devices, instruments, pharmaceuticals Staff flexibility, patient waiting time 1

2 RFID and Transfusion international: donation till hospital depot (passive) first trials with Temp Sense (semiactive) (DRK-BDS Sachsen, Dresden) patient identification by drug- and bloodapplication (Siemens New York and Saarbrücken) - patient identification by drug- and bloodapplication (Boston) - temperature control by hospital transports (Innsbruck, Vienna with Temp Sense) transponder hospital depot till patient (Washington) - ROI and influence on blood (Milwaukee) temperature control until transport with Vario Sens (DRK-BDS East, Dresden) ISBT - WPIT Task Force RFID founded at July 1 th 2005 in Athena invitation, aim and topics in 2005, 48 participants creation of two websites a) for internal use (BSCW-server) b) for official use ( 5 meetings till 2006 planned for 2008 June: final draft of a guideline for the use of RFID Devices in Transfusion Medicine 2

3 RFID -guideline: main topics technical overview and comparison with other Auto-ID s current usages in industry and health care implementation in transfusion medicine: - standardization - technical architecture - implementation methodology - validation tips risk assessment possible improvements in health care and transfusion medicine agreements - documentation and logistic processes faster and easier - can improve transfusion safety - frequency by direct contact:.56 MHz - the points of first implementation (pain points) are different in several blood banks - usage of ISO tag, switch to new HF item tag when it s available - buy readers with guaranteed future upgrade capability 3

4 Red Cross Blood Donation Services in Germany 4.5 Mill. donation/ year in Germany production of ~80% in 16 DRK-institutes ( ) 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) 4

5 Questions - tag survive harsh environment (e.g xg 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 buckling of labels - correct packaging, - sticking after separation (passive label on plasma bag can be used for RFID-identification of whole blood system) 5

6 Trials 2006/ semi-active Vario Sens Label (KSW Microtec AG, Dresden) first adapted readers metal cooling plates with problems regarded by the new transport system! 6

7 trials with tunnel reader: difficult Magellan technology with not tuned RFID-label with good results trial no. RBC readable In % speed Adjustment slow lengthwise slow lengthwise slow lengthwise slow lengthwise ,2 slow lengthwise ,3 slow lengthwise ,3 slow lengthwise - produced only with tag-uid, up to 700 data storable - correct measuring ±1 K compared to PT100-sensors - validation process with improvements (UV-light protection) -5, Temp.

10 Routine use - price for every red cell product to expensive (80 v. 6 ) - new generation with display to show dangerous temperature deviations possible to use for platelets ( v. 6 ) - now transport control in boxes (battery capacity for ~1 year) C 19,5 19,0 18,5 18,0 17,5 17,0 16,5 16,0 00:10 00:20 00:30 00:40 mean air temperature in the box during transportation 00:50 01:00 01:10 01:20 01:30 01:40 01:50 02:00 02:10 02:20 02:30 02:40 02:50 03:00 03:10 03:20 03:30 03:40 03:50 04:00 Future visions Donor identification prototype DRK-Donor Card 10

13 Conclusions Blood is a good single example for all drugs! RFID as barcode replacement is very expensive! 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 because it would be possible to do anything cheaper! Safer blood for Pakistan (Febr. 2007)
