There has to be a way to control how drugs are dispensed
In developed world - you need prescription - from doctor - emailed - then filed - and it easy to track. Even in Kenya big private hospital - it's done that way.
Public hospitals - manual papers - no tracking.
The same need to happen - those doctors prescriptions - need to be filed before pharmacist dispense drugs.
Otherwise pharmacist will steal the drugs.
Solution - design a system where doctor email the pharmacist - the pharmacist dispense the medicine.
It easy then to send auditors - and confirm if drugs sold matches prescriptions.
