Jurij F. Tasič Ph.D. Tržaška 25, SI-1000 Ljubljana, Slovenia Blood transfusion centre of Slovenia Marko Breskvar M.Sc., prof. Primož Rožman Ph.D. Šlajmerjeva 6, SI-1000 Ljubljana, Slovenia

2. Motivation Elimination of common administrative errors in blood transfusion process Administrative errors can be fatal (wrong blood for wrong patient) Every supermarket has better informatisation support

3. Starting points Introduction of tracking system into hospitals info system System compatibility existing systems future view Multiple areas of usage modular system structure enables simple portability and scalability System is adaptable to the area of usage System is adaptable to the users Personalization Simple usage (self-explanatory GUI functions)

4. Example of an application – blood transfusion Complete traceability of the blood transfusion process Elimination of the administrative errors Informatisation of specific steps of the transfusion Usage of the mobile and stationary terminals supporting the process Doctors make orders at the bedside rather than in their office Comprehensive backup of the hemovigilance Every step is logged and can be reviewed

5. Current situation – sources of administrative errors order Identification & sample transport identification Transfussion laboratory ProductIssue identification transport infusion BloodbankPATIENT BEDSIDE TEST

6. Main idea – Identification, traceability IDs of all the elements, participating in the process are electronically readable and connected in a database. That minimizes errors.

7. Proposed system services 1/2 User authentication and security Data storage and access (to more than one database) About patients About procedures (therapy, dignosing process) Online manuals Process traceability Defines and prescribes process – eliminate errors

8. Proposed system services 2/2 Remote decidion making support Automatic 2 nd opinion Communication between users Notifications to the users Urgent messages More formats  Picture  Speech (sound)  Text  “Whiteboard” User groups  Expert groups  Common interest groups

9. System modules Security, authorisation User interfaces (terminals, GUI) Data bases Client server connections Data acquisition Data processing Traceability

10. Practical system - idea

11. Practical system implementation - architecture

12. Some details Services are available via the mobile or stationary terminals Everything participating is equipped with unique human and machine readable ID.

13. Application topology
