Sleep quality in caregivers of patients with end-stage renal disease.

The aim of this study was to evaluate the self-reported quality of sleep among caregivers of patients who are receiving hemodialysis (HD) and peritoneal dialysis (PD). In 64 caregivers of patients of the University General Hospital of Evros in Northeastern Greece, who were receiving HD and PD, the following instruments were administered: Pitsburgh Sleep Quality Index (PSQI), Zung Depression Rating Scale (ZDRS), Self-Anxiety Scale (SAS), Well - Being Index (WHO- 5). The mean PSQI value of caregivers was 5.27 ±3.40 and 39% of them had poor sleep quality. "Poor sleepers" had significantly lower levels of quality of life (p=0.02), elevated levels of anxiety (p=0.006) and higher scores in the depression scale (p=0.009) compared to "good sleepers". In the regression analysis depression was found to have the greatest contribution to the variability of 'sleep quality' (standardized beta = 0.62, p<0.001) and quality of sleep seemed to improve as years of dialysis that the patient underwent increased (standardized beta = -0.28, p=0.007). Physicians should screen caregivers' sleep quality, especially during the first stages of the illness.
