How it works
From a status change to a released unit
Unit reserved
A blood product is reserved for a patient in the LIS.
Patient status changes
The EHR records discharge, transfer or death.
Dashboard flags it
SQL on harmonised FHIR data detects the mismatch in real time.
Unit released
The blood bank returns the unit to stock.
The problem
Blood products stay reserved for patients who have been discharged, transferred or have died, because reservation and patient status live in separate systems. Scarce units are blocked longer than needed.
What was implemented
EHR and LIS data harmonised in FHIR on the Firemetrics data foundation. Direct SQL queries run in real time and feed a Grafana dashboard for the blood bank.
The result
Reserved units for patients who no longer need them are detected automatically and become available again faster. The work was peer-reviewed and published in Transfusion Medicine (2025).
