Comparison of the effect of face-to-face and video diet training on the quality of life of hemodialysis patients: A clinical trial

Introduction: Adherence to diet in dialysis patients is one of the important care challenges that affect the quality of life. Education can change behavior by changing the level of awareness, attitude, and practice. Therefore, this study aimed to compare the effect of face-to-face and video-based diet training on the quality of life of patients undergoing hemodialysis. Methods: This study is a double-blind clinical trial conducted with 180 eligible hemodialysis patients in Mashhad in 2016 and 2017. They were randomly assigned to three groups face-to-face training, video-based training, and control. The intervention included two 30- to 45-minute sessions of diet training held once biweekly. Data were collected using a demographics form and the Quality of Life (SF-36) Questionnaire at baseline and 1.5 months after the intervention. Data were analyzed in SPSS software version 16 Descriptive and analytical statistics were performed using one-way ANOVA, Chi-square, and Kruskal-Wallis. The significance level was set at p < 0.05. Results: One-way analysis of the variance test showed that before the intervention of the three groups in the dimensions of physical condition, physical limitation, fatigue, mental limitation, social functioning, pain and general health were not statistically significant and only in the sense of well-being were statistically significant differences. (P=0.009), but after the intervention, there was a statistically significant difference in all dimensions except physical condition (P <0.05) and by Tukey post hoc test, it was found that this difference was in the video group with two groups of faces. It was significant for face and control, but no statistically significant difference was observed between the two groups of face to face and control. Conclusion The results showed that the total score of the quality of life after the intervention was higher in the video training group than in the face-to-face group. Therefore, the use of video-based training by health care providers to improve the quality of life of hemodialysis patients is recommended.
