The problem
what arrives at the pharmacy
Prescription instructions can arrive in shorthand. A pharmacist needs to confirm what each line means before it goes onto a label or into a record.

Constraints
what needs a pharmacist’s review
A pharmacist checks every line. Keystra leaves uncertain text for review and refuses uploaded files with patient identifiers before storing them.

What I built
what the pharmacist can do
Refuse files with patient details
An upload that may identify a patient is refused before the app stores it.
See Plate II.
Keep approved work consistent
The finished set uses the lines a pharmacist approved, so later changes do not silently replace them.
