Implementation and analysis of a non-floor stock controlled substance unit dose system in a pediatric hospital

Abstract

The purpose of this study was to evaluate the implementation of a modified unit dose dispensing system for schedule II controlled substances. Each dose is signed out of stock for the intended patient. Changes in the system required revision of dispensing records and procedures in pharmacy and nursing. After implementation the error rate for controlled substances was reduced to a level equivalent to non-controlled substances. A workload study was conducted in the pharmacy and on two general medical-surgical units. Small increases in workload occurred. Although this system is a modified unit dose system it does provide some of the safety features found in unit dose systems. Patient care benefits may decrease hospital liability in high-risk patients to offset cost factors.
