Medication adherence of elderly in Porto Alegre, RS

Polipharmacy and medication non-adherence are problems faced frequently in the treatment of elderly patients. An exploratory cross-sectional study and quantitative approach were conducted to assess the frequency of treatment-adherence in elderly and how polipharmacy can affect adherence. Four hundred and sixty six elderly answered a questionnaire in Porto Alegre, RS in individual interviews. The adherence frequency found was 173 (37.1%) and was higher among those, who use less medication. These results indicate the need for implementing educational programs for the elderly in order to help them to follow their drug therapy.
