One of the most important criteria for the evaluation of hemodialysis treatment process is the measure of dialysis adequacy. Dialysis adequacy is considered to the best therapeutic indicator for patient's clinical results and the best index for the assessment of the dialysis adequacy is the urea clearance. Although adherence accurate diet by patients is complement for hemodialysis and it is recommended for effectively control of symptoms of uremic syndrome and preventing longterm complications, many of these patients do not keep diet and fluid restriction and result in non-adequate dialysis, therefore, in order to improve dialysis adequacy, education, justify and emend patient’s attitude about diet necessity of following dialysis period times precisely and on time refers are very important. Due to the complexity of the treatment and care of hemodialysis patients, as well as the needs for adequate dialysis implement for to achieve effective treatment for these patients, by designing and run an educational program based on Health Education Models, dialysis adequacy can be improved.
