Sleep disturbances in patients with advanced chronic kidney disease

Abstract

Introduction: Patients with advanced chronic kidney disease suffer from a wide variety of physical and psychological symptoms. In final stages, they suffer significant alterations in physical, mental, emotional and social health, highlighting the impact on the quality of sleep. Objective: To analyse the main sleep disorders in patients with Advanced Chronic Kidney Disease (ACKD). Material and Methods: A cross-sectional descriptive observational study was carried out in the Nephrology Unit of the Reina Sofía University Hospital (Córdoba) in patients with ACKD in stages 4-5. Sleep disturbances were studied using the Pittsburg Sleep Quality Index questionnaire as well as the relationship with other variables such as age, sex, comorbidity, Haemoglobin, Serum Creatinine, and Body Mass Index. Results: 119 patients were studied, with a mean age of 67.61±14.89 years; 52 women (43.7%).The mean value of the Sleep Quality Index was 9.66±4 points. 83.2% of the patients had sleep disturbances (score> 5 points). A significant relationship was found with comorbidity and age. No relationships were found between sleep disturbances with sex, renal clearance or Body Mass Index. Conclusion: A large percentage of patients with ACKD in stages 4-5 have sleep disturbances. These alterations are related to greater comorbidity and advanced age; sex, renal clearance or Body Mass Index have not shown a relationship, at least in the sample studied.
