Comparing Sleep Quality in Patients Before and After Kidney Transplantation

Introduction. The purpose of the present study was to identify the prevalence of sleep disturbances in ESRD, and to compare the sleep quality before and after kidney transplantation. Methods. A semi-experimental study was performed on 40 participants with ESRD from September 2017 to September 2018 in Mashhad, Iran. Participants were in the waiting list of kidney transplantation, aged 18-years-old or more, had no history of any major psychological problems. They were excluded from the study if new medical condition or psychiatric disorder was initiated throughout the study. Patients' medical information including the duration of dialysis and laboratory data was extracted from medical records. Their sleep quality was assessed with the Pittsburgh sleep quality index (PSQI) within'-month prior the kidney transplantation and at the 3rd and 6th months after it. Collected data was analyzed using SPSS-16. P < .05 considered as significant. Results. The frequency of poor sleepers was 37.5%, 37.5%, and 20.0%; before the kidney transplantation, 3 months and 6 months after the surgery; respectively. The average sleep quality score decreased significantly 6-month post-operation compared to pre-transplant phase (P < 0.05). We found a significant relationship between the gender and quality of sleep before transplant surgery, whereas no correlation was found between sleep quality and the age, type or duration of dialysis, serum phosphorus or hemoglobin level, and the cause of kidney failure (P < .05, > .05, > .05, > .05, > .05, > .05, and > .05; respectively). Conclusion. Kidney transplantation has a positive effect on patients' sleep quality after 6 months.
