Usefulness of assessment of the Clinical Frailty Scale and the Dementia Assessment Sheet for Community-based Integrated Care System 21-items at the time of initiation of maintenance hemodialysis in older patients with chronic kidney disease.

INTRODUCTION

We examined whether the Clinical Frailty Scale (CFS), a widely adopted tool for stratifying the degree of frailty, and the Dementia Assessment Sheet for Community-based Integrated Care System 21-items (DASC-21), a simple tool for simultaneous assessment of impaired cognition and impaired ADL, at the time of initiation of hemodialysis is useful tool of older patients for the outcome and prognosis.

METHODS

Data for 101 patients aged 75 years or older (mean age, 84.3 years) with ESRD who were initiated on hemodialysis and could be followed up for a period of 6 months were reviewed.

RESULTS

The 6-month survival curves showed a significantly higher number of deaths in the frailty (CFS≥5) group than in the normal to vulnerable (CFS<5) group (p<0.01). The CFS level was also significantly higher (6.5±1.5) in patients who died within 6 months of dialysis initiation as compared with that (4.6±1.7) in patients who survived (p<0.01). On the other hand, the total score of DASC-21 was related to need for inpatient maintenance dialysis (p<0.01). The total score on the DASC-21 were found as showing significant correlations with the CFS level. The IADL outside the home was identified in the DASC-21 sub-analyses as being correlated with CFS.

CONCLUSIONS

The CFS and the DASC-21 appeared to be a useful predictive tool of outcome and prognosis for older patients being initiated on hemodialysis. Assessment by the CFS or the DASC-21 might be useful for selecting the renal replacement therapy by shared decision-making and for advance care planning.
