Who is sleeping more efficient? Patients on peritoneal dialysis or hemodialysis.

Sleep disorder, a common complaint among patients with the end-stage renal disease can affect most aspects of life. Therefore, we aimed to compare sleep quality of patients with peritoneal dialysis (PD) and hemodialysis (HD). This cross-sectional study was conducted on patients on dialysis who were referred to three major centers of Shiraz. The Pittsburgh Sleep Quality Index (PSQI) was used to compare sleep quality between patients on PD and HD. We also assessed some baseline characteristics to find out if they were independent predictors of sleep quality. Spearman correlation coefficients, one and two sample t-test, Chi-square, or Fisher's exact test were used to analyze the data. P <0.05 was considered statistically significant. The Statistical Package for Social Sciences version 18.0 for Windows was used for data analyzing. A total of 144 patients including 63 (43.8%) men and 81 (56.2%) women with the mean age of 54.4 ± 11.8 years completed the questionnaire survey. The total PSQI score showed that 77 (54.6%) of all patients had sleep disturbances without statistical difference between genders (P >0.05). On the other hand, the prevalence of sleep disturbance in HD patients (70.1%) was significantly higher than PD patients (35.9%), (P <0.001). HD patients had a higher rate of poor sleep quality than PD patients. Further studies are necessary to investigate the causes of poor quality of sleep in these patients and also to investigate methods to improve sleep quality in this population.
