Relationship between dialysis adequacy and sleep quality in haemodialysis patients.

AIM AND OBJECTIVES: The aim of this study is to examine the relationship between dialysis adequacy and sleep quality in haemodialysis patients. BACKGROUND: Sleep problems are common in haemodialysis patients. Dialysis adequacy is one of the factors associated with sleep quality. Studies evaluating the association between dialysis adequacy and sleep quality in haemodialysis patients present different results. DESIGN: Descriptive and cross-sectional study. METHODS: This study was performed with a total of 119 patients who had applied to dialysis centres for haemodialysis treatment between January and March 2014. The data collection form consists of socio-demographic and medical characteristics as well as laboratory parameters. A modified Post-Sleep Inventory was used to examine sleep quality in the research. RESULTS: There were no statistically significant relationship between sleep quality and dialysis adequacy (p > 0·05). When the Post-Sleep Inventory scores were evaluated according to sleep quality, 63·0% of patients had poor sleep quality, and 37·0% had good sleep quality. Sleep quality was worse in unemployed patients (X(2) = 4·852; p = 0·025) and patients who smoked heavily (Z = 2·289; p = 0·022). CONCLUSIONS: In this study, there is no statistically significant relationship between dialysis adequacy and sleep quality. However, it was found that the majority of haemodialysis patients had poor sleep quality. RELEVANCE TO CLINICAL PRACTICE: Even if the dialysis adequacy of patients is at the recommended level, their sleep qualities may be poor. Therefore, evaluations of the sleep quality of haemodialysis patients during the clinical practice must be taken into consideration.

Determination of the relationship between adequacy of dialysis and quality of life and self-care agency.

AIM AND OBJECTIVES: To investigate the relationship between the dialysis adequacy and the quality of life and self-care agency. BACKGROUND: Haemodialysis (HD), which is the leading treatment option for chronic renal failure (CRF), leads to significant changes in the life of the patient. These changes affecting almost all the dimensions of life also negatively affect the quality of life and self-care agency. DESIGN: Descriptive study. METHODS: The research was conducted with a total of 112 patients who had been admitted to two private dialysis centres between May 2009 and September 2010, who met the research criteria. The Data Collection Form for the Socio-demographic and Medical Characteristics, the Biochemical and Medical Parameters Form to determine the adequacy of dialysis, the SF-36 Quality of Life Scale and the Self-Care Agency Scale were used in the research. RESULTS: A significant relationship was found between Kt/V, one of the parameters used for the assessment of dialysis adequacy, and the emotional role scores of the SF-36 Quality of Life Scale and between the URR level and physical functioning (r = +0.192, p = 0.045) and emotional role scores (r = +0.284, p = 0.003). No significant relationship could be found between the self-care agency and the evaluated parameters. CONCLUSIONS: Kt/V and URR, which have an effect on dialysis adequacy, may affect the quality of life. Our results are similar to those of previous studies, which showed that Kt/V and URR affect the quality of life. RELEVANCE TO CLINICAL PRACTICE: It was recommended to regularly control the parameters used for the assessment of dialysis adequacy and to evaluate their effects on the quality of life, to determine the most affected quality of life subparameters and to address these problems and solve them.
