[Objectives] The study aimed to identify differences in the impact of dialysis methods (PD and HD) on ADL, the vital prognosis, and cognitive ability of the elderly aged 75 or over. [Method] Patients aged 75 or over, who went through sufficient SDM and were newly introduced to PD or HD, were included in either the PD or HD group and measured with KPS and the Barthel Index every three months and Revised Hasegawa Dementia Scale (HDS-R) every six months for a period of two years. [Results] During the two years starting on May 1, 2018, 18 patients were included in the PD group, and 40 patients were included in the HD group. The average age of the PD group (83.2±4.2) was significantly higher (p＝0.007) than that of the HD group (80.0±3.6). The amount of change of the Barthel Index and KPS from the baseline revealed significant improvement in the HD group, demonstrated by significantly higher scores compared with those in the PD group. Neither group showed any significant change in HDS-R scores during the observation. No significant differences between the two groups were observed in terms of the duration until death, ADL degradation up to KPS 30 or lower, and the loss of cognitive ability to the extent that continuation in the study was difficult. [Conclusion] ADL of the HD group showed significant improvement after the start of dialysis. The average age of the PD group was significantly higher than that of the HD group, but there were no significant differences in cognitive decline or the observation period.
