| Summary: | 碩士 === 義守大學 === 管理學院管理碩士在職專班 === 100 === The purpose of this study was to survey the relationships among the cardiac function, self-care knowledge, self-care behavior, and quality of life of hemodialysis patients, and to establish the model of the quality of life. Methods of this study are including purposive sampling and cross-sectional questionnaire. The research tools included: self-care knowledge scale, self-care behavior scale, the SF-12 quality of life scale, and a non-invasive cardiac output device. Data analysis included: descriptive statistics and structural equation model.
There were 136 hemodialysis patients who had received more than three months enrolled in the study. The mean of age was 61.82 years old. The correct rate of questionnaire of self-care knowledge was 72%. The mean of self-care behavior and fluid control behavior were 71.5 and 61.21%, respectively. The mean of overall physical function and mental function were 38.91 ± 10.83 and 40.97 ± 9.73, respectively.
The study used SEM to examine the integrated quality of life model. The findings showed that the older persons had worse self-care knowledge. The better the cardiac contractility, the better the quality of life. The findings also showed that patients have better self-care behavior but have worse quality of life. Hemodialysis patients maintained long-term restrictions on diet and water will result in their daily life under limited social activities and psychological distress.Diet and fluid control behavior were correlated with mental function of quality of life significantly. Therefore, if the patients are more rigorous in diet and fluid control behavior, they have worse quality of life. There was a significantly positive correlation between cardiac contractility, self-care knowledge, and quality of life. There was a significantly negative correlation between age, self-care behavior, and quality of life. The correlation bewteen self-care knowledge and quality of life was not significant.
It was recommended that nurses should afford the elferly clear and comprehensive relevant health education. For patients or families who were more rigorous in diet and fluid control behavior, the nurses should enhance psychological support and care, establish an effective communication bridge, provide well assistance to strength patients’ mental support, increase their self-care knowledge, thereby enhance quality of life of hemodialysis patients.
