| Abstract: | Insomnia is quite common in dialysis patients. The prevalence of insomnia was approximately 45-80% (Iliescu, 2004), but rare papers discussed the extents of insomnia caused by different dialysis modes. This study aimed to investigate not only the prevalence of insomnia, but also the impacts of demographic characteristics, the dialysis process factors, health behaviors, on the severity of insomnia in peritoneal dialysis (Peritoneal Dialysis, PD) and hemodialysis (Hemodialysis, HD) among patients with end-stage renal disease.
This was a retrospectively case study with convenient sampling design and constructed questionnaire data collection. The sources of data were 20 years old patients with at least three months experience of HD or PD. There were 94 patients in HD group and 30 patients in PD group enrolled from nephrology clinic in Taichung Tzu Chi Hospital from January till March of Year 2014. The study instrument included (1) basic information of the individual: socio-demographic characteristics, the dialysis process factors, perceived health behavior and healthy status, (2) measurement of Perceived Stress Scale, and (3) measurement of Pittsburgh Sleep Quality Index (PSQI). SPSS software package of version 12.0 was employed as a statistical tool to proceed the descriptive and inferential analyses.
In 94 cases of HD group, there was 56 males (59.6%) and 38 female (40.4%). The distribution range of their PSQI score were 1-19 scores, with averagely 10.18 scores (standard deviation was 4.7). In addition, there was 85.1% reached a standard level of insomnia (i.e., score > 5 points). The linear regression analysis shown there was a significant relationship between perceived stress and insomnia (ß=0.410, P< 0.001). On the opposite, in 30 cases of PD group, there was 7 males (23.3%) and 23 female (76.7%). The distribution range of their PSQI score were 1-16 scores, with average of 10.4 scores (standard deviation was 4.7). In addition, there was 86.7% reached a standard level of insomnia (i.e., score > 5 points). The result of linear regression analysis didn’t show any significant relationship among all independent variables and insomnia in PD group.
Our study failed to demonstrate the statistical difference on the prevalence rate of insomnia caused by HD (85.1%) and PD (86.7%) patients with end-stage renal disease. However, our study showed the cause of insomnia of those end-stage renal disease patients using hemodialysis mode was statistically correlated with their perceived stress. |
