Background: Elderly patients affected by chronic kidney disease (CKD) and end-stage renal disease (ESRD) are rapidly increasing. Elderly renal patients are frail and more susceptible to impair the nutritional status. Nutrition in elderly patients with chronic kidney diseases is important in decreasing complications and improving their quality of life (QOL). Study aim: To detect the effect of educational nutritional sessions on quality of life, functional and nutritional status among elderly patients with CKD. Design: Quasi-experimental research design. Settings: This was an interventional study that was conducted in the hemodialysis unit at Assiut university hospital. The program was conducted on elderly participants with CKD. Tools: Five tools were used to conduct the study. Tool I: Structured interview questionnaire: It include socio-demographic characteristics and medical data. Tool II: Kidney Disease Quality of Life Short Form Arabic version (KDQOL-SF). Tool III: Karnofsky Performance Scale Index. Tool IV: Mini Nutritional Assessment Scale. Results: the present result revealed that the elderly patients' QOL had improved as high quality of life score increase to more than two fifth in posttest & follow up for study group. Also there was statistically significant difference between pretest and posttest regarding functional and nutritional status P= 0.000*. Conclusion: The results indicate that the nutritional educational sessions had significant positive effect on elderly patients' QOL, nutritional, and functional status before and after intervention. Recommendations: Conduct Periodical educational and training program to elderly and their caregivers about therapeutic nutrition to improve their quality of life, functional and nutritional status.
