Quality of Sleep & its Relationship to Quality of Life in Hemodialysis Patients in Medical Training Centers of Tabriz and Maragheh, 2012.

Abstract

Abstract: Introduction: Despite many advances in the treatment of chronic renal failure, the quality of sleep in the patients who suffer from chronic renal disease, is at the risk. Too much prevalence of sleep disorders in hemodialysis patients, which is concomitant with physical, behavioral and psychological problems, has always affected these patents' quality of life. This study aimed to determine the relationship between quality of sleep and quality of life hemodialysis patents. Methods: By using a descriptive and correlational design, this study was conducted on 245 hemodialysis patients in 2012. Patients were selected by convenience sampling from the hemodialysis ward of four training hospitals of Tabriz and Maragheh. Quality of sleep was measured by the Pittsburgh Sleep Quality Index (PSQI), and the quality of life for patients was measured by the Kidney Disease Quality Of Life questionnaire (KDQOL-SF). Results: 83.3% of hemodialysis patients had poor quality of sleep. Poor quality of life was significantly associated with poor quality of sleep. There was a significant negative correlation between global PSQI and important aspects of quality of life including physical health, symptoms and problems, the impact of kidney disease on daily life, burden of kidney disease, mental health, social support, and sexual function, cognitive function and quality of social interactions. The quality of life and sleep was lower in older patients. Females had lower sleep quality. Lower quality of life had significant correlation with housekeeping, unemployment, and low income. Conclusion: The low quality of sleep in hemodialysis patients has an effect on the deterioration of their quality of life. Therefore, training, counseling, and advocacy programs should be developed to improve the patients’ quality of sleep and quality of life, especially those with lower education level and income, and older people.
