Chronic kidney disease (CKD) is a serious health problem due to high mortality and morbidity, negative impact on the patients' quality of life (QOL), high diagnostic and therapeutic cost, and the burden on society.
Sleep, which is one of the main needs of the human body, is important regarding the health and QOL in all ages. The objective of the study was to plan the quality of sleep and life quality in adults with CKD.
In this study, the researchers determined that the QOL and sleep decreased significantly in patients with ESRD, who underwent renal replacement treatment, compared to healthy subjects.
The increasing prevalence of CKD became an international health problem and drew attention worldwide. CKD is a serious health problem due to high morbidity and mortality, prominent impact on the patient's QOL, high diagnostic and therapeutic cost, and high burden caused in the society.
In the past published version of the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (K/DOQI), it was recommended that patients with CKD, who had a GFR less than 60 mL/min/1.73 m2, should be regularly followed up regarding renal functions and related complications. In addition, the evaluation of patients' QOL was recommended. QOL does not only provide information about the daily life of the CKD patients but also about their functional condition.
Pittsburgh Sleep Quality Index
Total 240 cases (91 healthy volunteers, 75 predialysis patients, and 74 hemodialyses (HD) patients) were included in our study. The study was designed as a prospective survey with a face-to-face interview method.
The sleep quality was evaluated with the Pittsburgh Sleep Quality Index (PSQI). The WHO Quality of Life-short version (BREF) survey questions were used for QOL, and scoring was performed.
The analysis showed that the results of PSQI scores, QOL scores, and evaluation of the age variable were statistically significant (P = 0.001, P < 0.001, P < 0.001, respectively).
Likewise, the PSQI scores were low in healthy volunteers but were the highest in predialysis patients. The scores of the HD patients were between the scores of predialysis and healthy volunteers.
The score of the QOL increased with educational level. There was a positive correlation between Modification of Diet in Renal Disease (MDRD) level and QOL (P < 0.001; r = 0.260) and a negative correlation between MDRD level and PSQI score (P < 0.001, r = −0.202).
Like in HD patients, close follow-up of predialysis patients with CKD is critical considering the resolution of the encountered problems. The researchers believe that the increase in QOL and sleep in patients with CKD may decrease the morbidity.
