A study was set to define a suitable procedure of quality assurance, a
iming to define quality measurements and develop assessment questionna
ires. The exercise started with a survey of products and services offe
red by individual centres. The need for a mission statement emerged as
a prerequisite to any quality definition. Objectives for a hypothetic
al drug information centre were drawn. Essential common quality indica
tors adequate to the full range of products were identified. Specific
quality indicators for each product have also been produced. Recommend
ations on assessment techniques were defined and follow up measures we
re indicated. Overall assessment of the service was not tackled as res
ourcing was considered critical for the production; individual paramet
ers were not weighted, as the weakest ring in a quality chain defines
the overall quality of the product. The understanding of needs and que
ries of customers emerged as crucial to the achievement of quality; in
dications were given as how to proceed in case of a direct contact wit
h end customers being impossible. Drug information professional's resp
onsibilities were also stressed, particularly in the case of a 'negati
ve' answer.
