The custody chain
A supply is prepared, then sent to a ward, returned or destroyed. Every step records who did it and when, so the whereabouts of a supply is never a matter of memory.
Prepare supplies and follow them to the ward, back to pharmacy, or to destruction. Keep the list of what this facility stocks and on what terms.
A supply is prepared, then sent to a ward, returned or destroyed. Every step records who did it and when, so the whereabouts of a supply is never a matter of memory.
A quantity is kept exactly as you type it. Nothing converts or recalculates it, because a system that quietly reinterprets a quantity can be wrong while looking certain.
If the formulary marks a medicine as a controlled drug, destroying a supply of it requires a named witness, and the witness cannot be you.
It says what this facility keeps and on what terms. It does not stop anyone prescribing a medicine that is not on it.
Each medicine has exactly one entry, so the answer to whether it is kept here is never two answers. If somebody else changes an entry while you have it open, your change is refused and you are asked to reopen it.
While preparing a supply, a pharmacist or administrator can choose Add medicine to the formulary at the foot of the list. The formulary form opens above the supply and the medicine comes back chosen. If the medicine is already on the formulary you are offered that entry instead of making a second one.
