Abstract

Many previous studies on medication adherence reported a variety of obstructing factors. However, problems such as leftover drugs and low medication adherence have not been fully solved at medical practice sites. Therefore, this study took note of the two dimensions of medication non-adherence: intentional and unintentional non-adherence, which are receiving increased research attention. An Internet survey on patient awareness and behaviors that are associated with health was carried out in February 2018, targeting approximately 30,000 ordinary citizens in their 45 and older, the age when medical needs increase. We measured component concepts based on previous studies, such as intentional medication non-adherence, unintentional medication non-adherence, patient empowerment (information searches, knowledge development, and decision participation), and so on, and then divided the subjects into chronic disease patients (the “chronic group”) and those who visit medical institutions only during the acute phase of an illness (the “acute group”). We conducted population-specific analyses using structural equation modeling. Among acute patients, the effect from unintentional on intentional non-adherence was significant, but among chronic patients, the effect was recursive. Although there were differences between affecting factors, there is a need to investigate varying support measures for chronic and acute phase patients. Our findings showed the possibility that excessive desire for knowledge development was linked to intentional non-adherence via inappropriate acquisition of knowledge and other acts. The results also suggested that acute-phase subjects had a greater likelihood of forgetting to take medications, followed by intentional non-adherence of taking medication. We believe it necessary, therefore, for medical professionals to use these outcomes as a basis for providing assistance to ensure medication adherence.
