ASHP Statement on Unit Dose Drug Distribution
The unit dose system of medication distribution is a pharmacy-coordinated method of dispensing and controlling medications in organized health-care settings.
The unit dose system may differ in form, depending on the specific needs of the organization. However, the following distinctive elements are basic to all unit dose systems: medications are contained in single unit packages; they are dispensed in as ready-to-administer form as possible; and for most medications, not more than a 24-hour supplya of doses is delivered to or available at the patient-care area at any time.1,2
Numerous studies concerning unit dose drug distribution systems have been published over the past several decades. These studies indicate categorically that unit dose systems, with respect to other drug distribution methods, are (1) safer for the patient, (2) more efficient and economical for the organization, and (3) a more effective method of utilizing professional resources.
