MO705SLEEP DISTRUBANCES IN PATIENTS ON PERITONEAL DIALYSIS

Abstract

Background and Aims Sleep disturbances are more common in patients with chronic renal failure and on dialysis than in the general population. They affect their mental health and quality of life. The objective of this study was to evaluate the sleep disorders of patients on peritoneal dialysis (PD). Method We report the results of a descriptive cross-sectional study in 27 patients on PD in order to assess the quality of sleep in these patients and its relation with mental health and quality of life. Sleep quality was performed using the Pittsburgh Sleep Quality Index (PSQI) to assess origin and extent of sleep disorders. Anxiety-depressive disorders were assessed using the HAD (Hospital anxiety and depression) scale. The quality of life (QOL) measurement was performed by the SF36 and KDQoL. Results We included 15 men and 12 women with an average age of 45.74 years (21–77). Eleven patients were on automated peritoneal dialysis (APD) and 16 patients on continuous ambulatory peritoneal dialysis (CAPD). The mean duration of dialysis was 45.77 ± 25 months. Poor quality of sleep was reported in 14 patients. The mean PSQI was 7.22 ± 4.87. The most affected components were sleep duration and usual sleep efficiency. Depression was objectified in 22.22% of patients and 26% of patients had anxiety. Impaired quality of sleep was associated with decreased quality of life. The components of the physical dimension of quality of life: limitation due to physical condition, physical pain were significantly lower in dialysis patients with good quality of sleep (p=0.014, p= 0.033 respectively) The mental dimension component of QOL of SF36: relationship to others, limitation due to mental condition was also lower in patients with sleep disturbances (p=0.039, p= 0.036 respectively). Symptoms and problems, as well as the effects and the burden of kidney disease were not associated with poor quality of sleep. Impaired sleep quality was also not significantly associated with depression or anxiety in our series. Conclusion Sleep disturbances are common in PD patients and are associated with decreased quality of life. Therefore, they must be taken into account in the therapeutic measures recommended in order to improve the quality of life of these patients and reduce morbidity and mortality.
