ObjectiveTo understand the psychological resilience, weakness and quality of life of elderly patients with maintenance hemodialysis(MHD), analyze the correlations among three, and study the mediating role of psychological resilience between frailty and quality of life in elderly patients with MHD.

MethodsA cross-sectional study was conducted in 50 patients with MHD aged ≥60 years in the department of nephrology.The general data questionnaire, fateful scale, quality of life scale and mental resilience scale were used for measurement and investigation, and the statistical analysis and mediation effect test were conducted.

ResultsThe frailty score, psychological resilience score and quality of life score in elderly patients with MHD were (6.28±2.53)(22.05±6.86) and (53.55±17.24) points, respectively.The results of correlation analysis showed that the frailty was negatively correlated with the life quality and psychological resilience(P < 0.01), and the psychological resiliencewas positively correlated with life quality(P < 0.01).The results of mediation effect test showed that the psychological resilience partially mediated the relationship between frailty and quality of life, and the mediation effect accounted for 27.0% of the total effect.

ConclusionsAmong the elderly patients with MHD, the frailty is significantly negative correlation with the life quality and psychological resilience, the psychological resilience is significantly postive correlation with life quality, and the psychological resilience partially mediates the relationship between frailty and quality of life.
