Pharmacist-manned drug information centers (DICs) were surveyed in early 1976 to obtain current information concerning the status, availability and scope of their services. Eight-six institutions believed to be active in disseminating drug information were surveyed; 74 responses were usable. Descriptive information on the respondents is tabulated. It appears that DICs make constructive contributions to enhancing drug therapy. Respondents at 63 of the centers believed, and 31 DICs said they have demonstrated, that physicians who used their services often changed their drug therapy based on answers supplied by the centers.
