Prescription drug use among ambulatory elderly in a Swedish municipality.

OBJECTIVE

To analyze prescription drug use among the elderly in a Swedish municipality.

METHODS

The municipality of Tierp, located in mideastern Sweden, is a well-defined geographic area that includes both rural areas and a few small, industrial towns. All people aged 65 years and older (n = 4769) as of 1986 in a total population of 21,000 inhabitants were included in the study. Their drug use was studied by registering all prescriptions filled by the pharmacies in the area.

RESULTS

Most of the elderly (> 70 percent) obtained at least one prescription during the year studied. Drug use was more common among women than men. However, the difference between men and women was much smaller among those aged 85 years or more. The drugs most commonly prescribed were cardiovascular, psychotropic, and analgesic agents. Furthermore, the study showed that simultaneous use of several drugs was quite common. One-fourth of all people aged 65 years and older used drugs from at least four different pharmacologic groups.

CONCLUSIONS

Our results revealed widespread use of prescription drugs among the elderly. An important finding was extensive drug use among men aged 85 years or more. This age group is increasing and there is need for further studies of its medication use.
