Non-compliance to diet and increased fluid intake can lead to unpleasant side effects and premature mortality in hemodialysis patients. Intervention strategies in educational and cognitive-behavioral domains can be used to improve diet compliance and restrict fluid intake in hemodialysis patients. The present study aimed to implement a participatory care model on diet compliance in patients undergoing hemodialysis referred to the Urmia Hemodialysis Center of Urmia in 1397. The present study is an experimental-randomized study that was performed on 60 patients undergoing diet without hemodialysis referring to Urmia Hemodialysis Center of Urmia. From 175 patients undergoing hemodialysis based on laboratory parameters of non-compliance patients and 60 patients were selected based on simple randomization and were randomly divided into intervention and control groups. After intervention steps of participatory care, diet compliance of the two groups was compared using the results of the comparable laboratory parameters. Analysis of the results of the present study showed that the collaborative care model significantly improved the results of laboratory parameters related to diet compliance in the intervention group compared to the results of the laboratory parameters before the intervention and the control group (p <0.05). Based on the results of the present study, it seems that participatory care intervention can be useful in improving diet compliance and fluid restriction in hemodialysis patients. The aim is to improve the quality of life of hemodialysis patients.
