24-hour unit dose dispensing of class III-V controlled substances.

Methods of controlling controlled substance (CS) inventories in unit dose dispensing systems vary. The two extremes are total floor stock of all CS drugs by the use of declining inventory signout sheets on the nursing unit to controlling only Class II and a few selected class III-V items. The method described herein outlines a systematic approach to controlling items on an individual patient basis consistant with the benefits of unit dose dispensing. A CS card assigned to each patient for each of his required controlled substance medications serves as an audit trail for doses consumed by the patient and provides a declining inventory receipt when returned to the pharmacy.
