Terminology and coding systems of drugs--CDrugs

The average patient contact that results in a drug prescription depends on the organizational environment. Nevertheless, in any country, more than half of patient contacts results in a prescription. On average in Belgium--a country with a free liberal medicine--more than 80% of the GP-patient contacts results in some kind of medicinal product prescription. Linkage with a drug knowledge base is thus a very important, sometimes even essential, requirement in developing a health information system.
