Currently, waste prompts only occur when an item is being charged, either by the pharmacist (manual charge entry) or the nurse (when charted as administered on the MAR -charge on admin). THis is not helpful when waste is complicated, as in IV infusions admixed from different sized vials, etc - very frequent with shortages! Only the pharmacy knows what was used and what is actually wasted in IV admixtures, but for the administering nurse (who subsequently charges upon admin), they do not know what the correct waste amount may be. Please modify order entry so that if there is a waste prompt, it will come up during order entry, and the nurse can just approve what is already entered.
