Electronic data interchange for pharmacy inventory control.

The use of electronic data interchange (EDI) for controlling pharmacy inventory at a 303-bed hospital is described. The hospital, which belongs to a group purchasing consortium, uses EDI to exchange information with its primary drug wholesaler. The pharmacy's personal computer and software provided by the wholesaler are used. EDI enables the pharmacy to (1) select and order items by using hand-held bar-code scanning devices, (2) upload this information into the pharmacy's computer, (3) review the order before transmission, and (4) access the wholesaler's inventory. The pharmacy also uses EDI with its primary i.v. supplier. Using EDI for placing the daily pharmaceutical and i.v.-supply orders reduces by one half the daily time expenditure for purchasing. In addition, EDI provides various inventory-related reports. EDI provides an efficient and effective way to control pharmacy inventory.
