Impact of a pharmacist education program on nonformulary drug use.

: The effect of an educational program for pharmacists that included instructions for handling nonformulary drug requests and determining suitable formulary alternatives for frequently prescribed nonformulary drug requests was measured. Results indicate a significant increase in the number of appropriate nonformulary drug dispensings when the postintervention phase was compared with the preintervention phase. Other values, including the financial impact per nonformulary drug request, did not differ significantly between the two phases. Since all nonformulary drug requests require pharmacist time, a more cost-effective nonformulary drug policy might focus the pharmacist's efforts on nonformulary drug products that are more costly than their formulary alternatives.
