The feasibility of barcode-based dispensing quality assurance programs.
A study was conducted to evaluate the feasibility of using barcodes in an outpatient pharmacy quality assurance program. In the first step of this study, adhesive labels containing a barcode representation of the National Drug Code (NDC) identification for the hospital's formulary medications were printed for each stock bottle or drug package used in dispensing. When an outpatient prescription was presented to the pharmacist, a label containing a barcode representation of the NDC identification for the prescribed medication was generated on-line and attached to the back of the prescription form. After the prescription item was filled by the pharmacist, an automated check was performed with a scanning wand by comparing the barcode on the prescription with the previously generated barcode on the stock bottle or drug packaging. A match indicated that the correct medication had been dispensed. Elaborations on this basic automated system for a barcode-based dispensing quality assurance program are suggested.
