  6. Laboratory Point Of Care Testing • Tests of clinical biology, performed on point of care or patient bedside • In vitro tests: performed on a specimen, not on the patient itself • Usually quick tests, specimen collected, tested at once and eliminated • No pre or post-processing (like in LDA) • Results used immediately by the care provider in its clinical decisions • Supervision by a clinical laboratory of the healthcase enterprise • Training provided to the ward staff  good practices on specimen and analyzer • Provision of reagent • Supervision of quality control • A posteriori clinical validation IHE Interoperability Workshop

  7. Contraints and benefits of point of care testing • Results obtained at once  increases the efficiency of clinical decisions • Minimizes the blood quantity drawn from the patient, because of the immediate use of the specimen. E.g. Two drops are enough to test blood gaz, electrolyte and hematocrit of a new-born baby. • Preserving a high level of quality of the POCT process requires its supervision by a clinical laboratory. (This is at least agreed upon in US and Europe) IHE Interoperability Workshop

  8. Examples of LPOCT devices • Portable blood gaz and chemistry analyzer used by the nurse on patient bedside • Blood gaz analyzer permanently installed in a surgery theater • Coagulation analyzer in acute care ward • Glucometer used by the patient in home care • Work station on which the nurse manually enters the results of pregnancy stick tests.

  12. Laboratory Information Reconciliation • Match clinical lab observations produced on specimens collected from misidentified or unidentified patient with the patient’s record. • Match clinical lab observations produced on specimens with orders created afterwards, either in the Order Placer or in the Order Filler application. IHE Interoperability Workshop

  13. Other extensions • Upload Quality Control Results from analyzers to Order Filler (via Automation Manager) • extension of LSWF profile • Publish lab reports in clinical electronic documents • LIS in the role of Document Source in XDS profile IHE Interoperability Workshop

  14. Schedule • Face to face meeting in May (date to adjust) • Public comment version end of May • Trial Implementation version 2.0 end of June • Thank you for your attention… IHE Interoperability Workshop
