Total formulary review--the easy way.

In an effort to minimize drug costs, many hospital pharmacy services have limited their drug inventories through the development of a formulary. Evaluation of drug products for addition to the formulary is the responsibility of the Pharmacy and Therapeutics (P & T) Committee. The deletion of rarely used or outdated products is often overlooked. As a means to "clean up" the formulary, Hamot Medical Center (HMC) underwent a total formulary review. Drugs were separated into classes as defined by the American Hospital Formulary Service (AHFS). Approximately three drug classes were evaluated each month by the P & C Committee. Evaluation criteria was based on the following factors: current formulary status, usage statistics, negative comments appearing in six current publications, hospital acquisition cost, and number of formularies containing each product. A final compilation of all deletions and additions were distributed to all medical staff department and division chiefs. Following receipt of all their comments, a final draft of the formulary was made and prepared for publication. This system is a simple, uncomplicated means of either revising or beginning a formulary. It evaluates a drug based on efficacy, individual hospital usage, and cost of the drug while allowing for input of the medical staff. The end result is a formulary tailored to best fit each institution.
