I presume you meant vials and not files. I process physicians orders from my home for up to 27 different facilities. It's true that very few use the vials; but, those who do are generally large facilities who use enough of it to warrant the added labor expense to draw them up and reap the savings of reduced wastage. Enox was, and probably still is, the #1 line item in terms of drug budget so the reduced wastage savings can be substantial.
