Objectives: The aim of this research is to examine the need for mental health care in chronic patients on haemodialysis with special emphasis on the importance and role of nurses in providing psychological support to their patients. Study design: The survey was conducted as a cross-sectional study during the month of February 2022. Participants and Methods: 61 patients from the chronic dialysis treatment program at Karlovac General Hospital were included in this research. For the purposes of the research, three questionnaires were used; the socio-demographic characteristics questionnaire, the BAI questionnaire (Beck Anxiety Inventory) and the BDI questionnaire (Beck Depression Inventory). The ANOVA test examined whether there were statistically significant differences in anxiety levels over the years of haemodialysis treatment, as the distribution of the BAI variable did not deviate from normal. Data were examined at the significance level p <0.001. The chi-square test was used to test the hypothesis. Results: The results show that kidney patients treated with chronic dialysis are equally genderdistributed and most of them are retirees. They have been treated with dialysis mostly within the first five years. Most of them are married and elderly. No statistically significant difference in anxiety levels was found with respect to years of haemodialysis treatment. Patients treated with haemodialysis for more than five years were found to have the highest average level of anxiety, i.e. an average level of 28.9 with an average deviation from the arithmetic mean of 10.9. In terms of statistical significance, there were more patients with severe depression (n = 29; 47.5%). The study did not show a difference in the level of depression in patients with respect to years of haemodialysis treatment (F = 0.33; P = 0.723). Conclusion: Given the results of the study, it can be concluded that patients with chronic renal failure on dialysis treatment need the psychological support of health professionals, in which nurses also play an important role.
