Summary AbstractIntroduction: Sleep disorders are frequently reported in hemodialysis and peritoneal dialysis patients, but there are no studies investigating the dreams of these patients. This study was an examination of differences in the level of dream anxiety between hemodialysis patients and peritoneal dialysis patients. A comparison of depression and anxiety symptoms, sleep quality, and sleepiness between these 2 groups was also performed. Methods: In this observational, cross-sectional study, 49 hemodialysis patients and 29 peritoneal dialysis patients treated at an outpatient nephrology clinic were enrolled. A sociodemographic data collection form, the Van Dream Anxiety Scale, the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, and the Beck Depression and Anxiety Inventories were administered, and hemoglobin level and fractional clearance of body water by dialysis (Kt/V urea) were measured. Results: There were no significant differences between the groups in terms of dream anxiety (p=0.517), depression (p=0.889), sleep quality (p=0.221), insomnia severity (p=0.152) or hemoglobin level (p=0.505). Discussion and Conclusion: We did not find any significant difference in the level of depression, anxiety, sleep quality, or insomnia severity between hemodialysis and peritoneal dialysis patients in our study. Similarly, the level of dream anxiety was consistent with these findings.
