Executive summary. A single “filled” status hides the intake, verification, adjudication, preparation, pickup, reversal, return, and correction events operations depend on.
Definition
An event model records discrete, time-stamped changes in a dispensing workflow and derives current status from those events.
Name meaningful operational events
Capture the events that change responsibility, patient access, inventory, claim state, or safety review. Inventing micro-events that staff cannot reliably distinguish adds noise rather than resolution.
Each event carries an actor or source, a timestamp, an identifier, and a correlation to the prescription or dispense record.
Derive state without losing history
Current state drives work queues. It must not overwrite an earlier verification, reversal, or return-to-stock event, because those are what an investigation reads.
Represent corrections as new events with a reason, so reporting can tell a corrected record from an original fact.
Frequently asked questions
Why not store only the latest dispensing status?
The latest status cannot say what changed, when it changed, or why an inventory or claim balance now differs.
