RELIS Vest provides drug information by answering questions from mainly physicians and pharmacists. In the present paper we evaluated this service. All questions to RELIS Vest during the 1995-98 period were systematically categorized and analysed. The quality of the service was assessed by evaluation forms. Of a total of 875 queries, 393 came from physicians and 370 from pharmacists. 42% were about psychoactive drugs; the most frequent types of queries concerned documentation and adverse effects. Analysis of 180 evaluation forms showed that 79% of the physicians and 56% of the pharmacists found the answers fast enough, relevant, adequately comprehensive and with valuable references while 16% of the physicians and 29% of the pharmacists found that the answers satisfied three of these four criteria.
