Scope of LPOCTScope of LPOCT
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
Clinical validation a posteriori

Contraints and benefits Contraints and benefits of point of care testingof 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)

Examples of LPOCTExamples of LPOCT
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.

The IHE actors of LPOCTThe IHE actors of LPOCT
Point Of Care Result Generator (POCRG)
Produces the results from a specimen• By measurement of an analyte on a specimen• By calculation• By manual enter
Point Of Care Data Manager (POCDM)
Handles and administers a set of POCRG• Controls the process, • checks the patient identity and location• Collects the patient results • Collects and manages the QC results• Forwards the results to the Order Filler

Order Filler
Recipient of POCT results• Stores the results within matched or generated orders• Performs the clinical validation• Optionnaly, centralizes the QC results

The POCDM has the choice between dowwnload The POCDM has the choice between dowwnload and query to obtain patient informationand query to obtain patient information
ADT• Downloads tp POCDM patient demographics and visit data
Patient Demographics Consumer (PDC)• Grouped with POCDM, queries for patient and visit data
Patient Demographics Supplier (PDS)• Responds to queries from PDC grouped with POCDM

Workflow using the query methodWorkflow using the query method
PDS
POCRG
3) PDC queries PDS with the patient ID
7) POCRG sends the results
8) POCDM accepts the results, stores them, and forwards them to the Order Filler
POCDM2) POCRG sends this data
PDC
1) : The nurse identifies herself, scans the patient ID and selects the tests to perform
4) PDS sends the patient identity and location
5) POCDM sends back the patient identity
6) : The nurse checks the patient identity, perforrms the tests and uses the results
9) Order Filler matches an existing order or creates a new one, and stores the results within
10) Clinical expert validates the results
