Abstract

Purpose This study was a descriptive study to identify the influence of illness perception, beliefs about medicine, and self-efficacy on medication adherence in patients with liver cirrhosis and provide the basic data for developing the nursing intervention program to improve their health.

Method The participants of this study were 150 patients with liver cirrhosis visiting P University Hospital, Busan. The data were collected from January 29, 2019 to April 17, 2019. The collected data were analyzed with SPSS 23.0 for windows, for descriptive statistics, t-test, ANOVA, Pearson’s correlation coefficient, and stepwise multiple regression after controlling drinking and complications.

Result 1. The mean score of illness perception was 6.78±.1.56, beliefs about medicines was 3.14±4.95, Self-efficacy was 7.99±1.56, and medication adherence was 14.25±2.82.

2. Medication adherence was different according to monthly income (t=2.005, p=.047), drinking (t=-2.246, p=.034), and complications (t=-2.907, p=.005). There were significant correlations between self-efficacy (r=-.337, p<.001) and beliefs about medicines (r=-.291, p<.001) and medication adherence.

3. In stepwise multiple regression, beliefs about medicines (β=-.234, p=.001) and self-efficacy (β=-.230, p=.002) were statistically significant predictors of medication adherence in patient with liver cirrhosis, explaining 26.9% of total variance (F=14.695, p<.001).

Conclusion Based on the results, the factors that had an impact on medication adherence in patients with liver cirrhosis were drinking, beliefs about medicines, self-efficacy, and complications. Based on this, if we emphasize the necessity of abstain from alcohol, teach people to improve their beliefs about medicines, improve self-efficacy, and provide nursing interventions for education about the management of complications, it is expected to be helpful for medication adherence and self-care in patients with liver cirrhosis.
