Survey of formulary system policies and procedures

A telephone survey was conducted to determine the policies and procedures of hospital formulary systems. Directors of pharmacy at a random sample of 150 community hospitals were interviewed, and letters were sent to each respondent requesting copies of the formulary and drug evaluation form. One hundred thirty hospitals completed the interview (gross response rate of 87%), and 35 evaluation forms and 49 printed formularies were received. Almost all hospitals had a formulary system and a printed formulary; the most frequently stated purposes were to decrease costs and to ensure appropriate therapy. Most formularies received were simple drug lists with no supporting information. The typical pharmacy and therapeutics committee consisted of 11 members, met every month, and reported to the executive committee. About 80% of the responding institutions had formal procedures for considering formulary additions. Less than half had standardized drug evaluation forms. Most hospitals have a formulary system and a printed version of the formulary; however, the formulary often serves primarily as a drug list, with no supporting information.
