Objectives: Since the first reports of the spread of the new SARS-CoV-2 virus, experts have pointed to the possible psychological consequences of the pandemic. In this study, we tried to answer the question of whether the level of perceived stress related to the pandemic affects the quality of life related to the disease and the functioning of patients on peritoneal and hemodialysis.
Methods: Out of 106 patients from the dialysis center of the University Clinical Hospital in Wrocław during the first wave of the pandemic, 73 patients were enrolled, including 61 hemodialysis (HD) and 12 peritoneal dialysis (PD). The study used The Perceived Stress Scale (PSS), The General Health Questionnaire (GHQ-28), The Impact of Events Scale-Revised (IES-R), and The Kidney Disease and Quality of Life (KDQOL-SF™).
Results: Nearly half of the respondents (48%) experienced psychological distress and 5.6% of the respondents showed clinically significant psychopathological symptoms (GHQ). Half of the study group declared a significant occurrence of post-traumatic stress symptoms (IES-R). A high score of subjectively perceived stress related to the pandemic was observed in both study groups. Numerous significant negative correlations were found between the results of the KDQOL subscales and psychopathological symptoms (IES-R and GHQ) without significant differences between the two groups (HD vs. PD). Almost all KDQOL subscales were significantly moderately or strongly correlated with the level of perceived stress related to the pandemic.
Conclusions: The level of subjectively assessed stress related to the pandemic and the severity of psychopathological symptoms, including post-traumatic stress, were significant in the entire group of patients undergoing renal replacement therapy, regardless of the dialysis type. Numerous confirmed relationships between the domains of the quality of life related to the disease and the level of perceived stress and psychopathological symptoms indicate an urgent need to provide effective psychological support to this group of patients and to develop preventive programs in the field of mental health of people undergoing renal replacement therapy.
