| Summary: | 碩士 === 義守大學 === 醫務管理學系 === 103 === Chronic renal disease is one of the 10 leading causes of death in our country. Organ transplantation is difficult, and donors are not easily available; therefore, most Chronic renal disease patients depend on hemodialysis treatment for survival. The current health care guide is based on paper materials; however, studies have reported the advantages of using multimedia-based visual effects for learning. Therefore,this study aimed to design interactive visual disks (DVDs) on diet control and feeding guidance for hemodialysis patients.We examined the influence of health education tools on the knowledge and behavior of patients. Furthermore,we examined the efficiency of the health education tools in improving diet control and serving as a clinical care reference for patients.
This study adopted a quasi-experimental design. Patients who met the inclusion criteria and agreed to participate in the study were divided into two groups： control and experimental groups (60 persons in each group). Blood samples for analysis were obtained from two hemodialysis centers in Southern Taiwan. We analyzed the data in the two groups before and after watching the DVDs. The experimental group received diet care intervention on DVD for 4 weeks, three times a week, in 10-minute sessions. The control group received routine health diet education. In this study, a purposive sampling approach was adopted, and we collected data using a structural formula questionnaire. The questionnaire comprised basic patient information; knowledge scales; and behavior scales for hyperkalemia, hyperphosphatemia, and water control. We performed comparative analysis of the serum phosphorus and potassium levels and the weight gain of the patients in the two groups. The effects of the dietary and care intervention DVDs on patients were measured after 4 weeks. Descriptive statistics, frequency allocation, the chi-square test, nonparametric Mann-Whitney U test, and various assays were used for data analysis.
The DVD diet care intervention improved the performance of the experimental group. The results of biochemical analysis (serum potassium and phosphorus levels and interdialysis weight gain) were more improved in the experimental group than in the control group (p < 0.05). Furthermore, the questionnaire scores on cognition and behavior for high- potassium and -phosphorus diets and water control were higher in the experimental group than in the control group (p < 0.001). The satisfaction levels with the DVD intervention were higher in the experimental group than in the control group (p < 0.001). Therefore,using DVDs can improve the diet knowledge and behavior of hemodialysis patients and facilitate their care. Patient satisfaction regarding the hemodialysis unit of health education is increasing. The health education approach used in this study can be applied to patient care and nursing at hemodialysis centers.
