Drug interaction microcomputer software evaluation: Drug Master 89

Drug Master 89 was evaluated using general and specific criteria. The installation process, ease of learning, and ease of use were rated excellent. The technical support, scope of coverage, and overall clinical performance were rated good. The quality of the clinical documentation and frequency of updates were fair, while the quality of the user documentation was poor. The program is valuable to the clinical dietician because of the comprehensiveness of its dietary and food interactions data base. For the practicing pharmacist, it performs reasonably well but other available programs are better values.
