Abstract
Medication non-adherence could be of two types: intentional and unintentional non-adherence. This study was aimed at determining the ratio of intentional to unintentional non-adherence among patients with chronic diseases and related factors. To this end, household members were targeted according to the 2017 annual data of the Korean Medical Panel Study (version 1.6), and the ratio of intentional to unintentional non-adherence in patients with hypertension and arthropathy was determined. The independent variables studied were demographic characteristics, drug satisfaction, side effects, psychosocial factors, diagnosis time, and financial parameters. The percentage of individuals with unintentional non-adherence was quite high among those with hypertension. On the other hand, the percentage of individuals with intentional non-adherence was quite high among those with arthropathy. Among individuals with hypertension, there was a difference between adherence and non-adherence rates according to age, diagnosis time, drug satisfaction, average monthly drug cost, drug cost burden and the number of chronic diseases. There was a difference between intentional and unintentional non-adherence rates according to average monthly drug cost and diagnosis time. In patients with arthropathy, there were differences in adherence rates according to age, household income, side effects, satisfaction, stress, and anxiety. There was a difference between intentional and unintentional non-adherence rates according to the number of chronic diseases. We expect that this study will be helpful in the development of intervention methods for managing non-adherence.
