Background And ObjectivesA geriatric assessment (GA) is a structural method for identifying frail patients. The relation of GA findings and risk of death in end-stage kidney disease (ESKD) is not known. The objective of the GA in OLder patients starting Dialysis Study was to assess the association of GA at dialysis initiation with early mortality and hospitalization.Design, Setting, Participants, And MeasurementsPatients ≥65 years old were included just prior to dialysis initiation. All participants underwent a GA, including assessment of (instrumental) activities of daily living (ADL), mobility, cognition, mood, nutrition, and comorbidity. In addition, a frailty screening (Fried Frailty Index, [FFI]) was applied. Outcome measures were 6- and 12-month mortality, and 6-month hospitalization. Associations with mortality were assessed with cox-regression adjusting for age, sex, comorbidity burden, smoking, residual kidney function and dialysis modality. Associations with hospitalization were assessed with logistic regression, adjusting for relevant confounders.ResultsIn all, 192 patients were included, mean age 75 ± 7 years, of whom 48% had ≥3 geriatric impairments and were considered frail. The FFI screening resulted in 46% frail patients. Mortality rate was 8 and 15% at 6- and 12-months after enrolment, and transplantation rate was 2 and 4% respectively. Twelve-month mortality risk was higher in patients with ≥3 impairments (hazard ratio [HR] 2.97 [95% CI 1.19-7.45]) compared to less impaired patients. FFI frail patients had a higher risk of 12-month mortality (HR 7.22 [95% CI 2.47-21.13]) and hospitalization (OR 1.93 [95% CI 1.00-3.72]) compared to fit patients. Malnutrition was associated with 12-month mortality, while impaired ADL and depressive symptoms were associated with 12-month mortality and hospitalization.ConclusionsFrailty as assessed by a GA is related to mortality in elderly patients with ESKD. Individual components of the GA are related to both mortality and hospitalization. As the GA allows for distinguishing between frail and fit patients initiating dialysis, it is potentially of added value in the decision-making process concerning dialysis initiation.© 2019 The Author(s) Published by S.
