Intake of drugs among elderly people in a Danish municipality, Rødovre.

Drug intake has been studied among a random group of persons, aged 75 or over, in Rødovre Municipality. Two hundred and eight-three elderly persons living in their own homes have been visited and interviewed about their daily intake of prescribed and nonprescribed drugs (including so-called natural drugs). Similar information was gathered from 146 elderly persons living in nursing homes. Thirty-one per cent of the elderly living in their own homes and 3% of those living in nursing homes did not use prescribed drugs daily. The median daily amount of different types of drugs used was 1.8 (range 0-10) for elderly persons living in their own homes and 4.5 (range 0-11) (p less than 0.001) for those living in nursing homes. Women living at home had a higher intake of drugs than men, especially diuretics. The most frequently used drugs were diuretics, sedatives/hypnotics, analgesics, digitalis and electrolytes. For all types of drugs a higher consumption, especially of phenothiazines, was found among elderly persons living in nursing homes. Drug consumption was independent of age and social stratification in both groups. The use of non-prescribed drugs ranges from 0 to 9 different types in the group living in their own homes, and from 0 to 5 in the group living in nursing homes--laxatives being the type most frequently used.
