Centralized drug list production in a multihospital system.

A project established to maintain individualized station drug lists for a nationwide network of hospitals and clinics is described. The structure of the drug lists and procedures used in their production are described in detail. A central location controls keypunching, data processing and printing. The pharmacist at each station is responsible for drug list maintenance. Each staton's formulary is stored on digital magnetic tape. Sharing development costs by all stations and using a single printing facility resulted in a cost-effective system.
