Medication adherence, Health literacy, Social support, older persons with heart failure


Older persons with heart failure are a group of people with complex problems who are often affected by multiple medications, so medication adherence is needed to reduce potential problems and complications. This research is a descriptive study of the relationship of factors associated with medication adherence among older adults with heart failure. The sample was elderly people who attended cardiovascular clinics in tertiary hospitals, with a specific sample of 84 people. Four questionnaires were used for data collection: a personal information form, the Functional Communication and Critical Health Literacy Scale, social support questionnaires, and the Medication Adherence Scale in Thai. Descriptive statistics were used to determine the demographic data. The correlation between variables was tested with Spearman’s rank correlation coefficient.

The results showed that most older adults with heart failure recruited from tertiary hospitals had high health literacy, with an average of 41.31 (SD = 9.49), and received a high level of social support at 73.80% with an average of 52.65 (SD = 6.98). The majority of those had adequate medication adherence, at 96.40 % with an average of 37.86 (SD = 3.50). Moreover, emotional social support had a significantly positive relationship with medication adherence in older adults with heart failure (rs = .296 p < .01).

The results of this study can serve as a basis for nurses to plan the promotion of medication adherence in older adults with heart failure.
