Treatment repeated, or missed
Without the last prescription, the next one is a guess.

What happens today
Tests are re-ordered because no one can see yesterday's result. Medicines are re-prescribed because no one can see what was dispensed. Interactions and allergies stay invisible until they present as harm.
Scarce drugs and reagents are spent twice, and avoidable reactions get through.
What replaces it, step by step
On the platformPrescribing runs interaction, allergy and duplicate checks against the patient's active medicines, and dispensing writes back to the same record.
Prescribe from the active medicine list
The prescriber sees what the patient is already taking, when it was dispensed and by whom.
Run the safety checks
Interaction, allergy and duplicate-therapy checks run against that list before the prescription can be issued.
Dispense against the prescription
The pharmacy fills the electronic prescription (no transcription, no guessing at handwriting) and records the batch actually given out.
Write it back to the record
The dispense event closes the loop on the same patient record, so the next clinician sees what was received, not what was intended.
