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.

본 연구는 약물 이행 모델을 기반으로 다제약제 복용 노인의 약물 불이행과 관련 요인을 파악하기 위해 수행되었다. 연구 대상은 서울과 경기도에 거주하는 다제약제 복용 노인 190명이었다. 연구 결과, 대상자의 43.2%가 임의로 처방된 약의 복용을 중단하는 의도적인 약물 불이행을 보였다. 의도적인 약물 불이행의 이유는 '증상이 조절된다고 느낄 때', '약을 복용하는 것이 귀찮고 불편해서', 그리고 '약을 복용하였을 때 더 나빠지는 것 같아' 순으로 나타났다. 또한, 다제약제 복용 노인은 능동적으로 약 정보의 내용 및 경로를 탐색하는 정도가 매우 낮았다. 의도적인 약물 불이행군과 의도적인 약물 불이행이 아닌 군 사이에 성별, 복용 약의 종류, 그리고 약물 부작용 경험에 따라 유의한 차이가 있었지만, 약 정보의 탐색 내용 및 경로에는 통계적으로 유의한 차이가 없었다. 본 연구를 통해, 다제약제 복용 노인의 의도적인 약물 불이행을 줄이기 위해서는 성별을 고려하고 복용 약의 종류를 확인하며, 약물 부작용 경험 여부를 사정하는 것이 중요하다. 그리고 능동적으로 약 정보의 내용 및 경로를 탐색하여 찾는 정도가 낮으므로 노인이 선호하는 경로를 통해 약 정보의 내용을 제공하여 다제약제 복용 노인의 약물 이행 의사결정 과정을 돕는 것이 필요하다.
