Abstract
This study was conducted to examine the medication non-adherence and related factors based on medication adherence model of older adults that use polypharmacy. A survey was used to collect data from 190 study participants. Among the 190 subjects, 43.2% did not adhere to their polypharmacy intentionally. The reason for medication non-adherence was listed in order of 'when they felt well on symptoms', 'when it was annoying and uncomfortable', and 'when they felt worse due to medication'. Moreover, the older adults often do not seek for medication information actively. Between adherence and non-adherence groups, while there were differences in gender, type of medication, and experience in drug-related side effects, there were no statistically significant differences in medication information contents and route. This study demonstrates that gender, type of medication, and experience in drug-related side effects should be considered to promote medication adherence. In addition, since the elderly with polypharmacy are rarely actively searching for the contents and route of drug information, the contents of drug information need to be provided by the route preferred by the elderly in order to assist in their decision-making process for polypharmacy.
