Background. The poor health outcomes of Renal Replacement Therapy (RRT) in the elderly has promoted Conservative Management (CM) as a therapeutic option in advanced chronic kidney disease. However, there is still a lack of evidence about prognosis of these patients; thus, the aim was to analyze the survival rate of elderly patients under CM and RRT and evaluate the variables related to the initiation of such treatments in clinical practice.
Methods. Prospective cohort study of RRT and CM patients >75años. Renal function parameters and geriatric assessments were carried out. This evaluation included: analysis of comorbidity, functional, cognitive, frailty, nutritional and socio-family status.
Results. Cohort of 37 RRT and 82 CM patients. CM patients were significantly older, with more frequency of history of vascular event, more comorbility (Charlson), worse functional situation (Barthel), higher risks of cognitive impairment (Pfeiffer) and malnutrition (MNA-SF), and higher frailty and socio-familiar impairment. Mortality rate was lower in RRT patients (8.72 vs. 3/1,000 patients/month; HR= 0.37, p=0.018), but survival advantage reduced drastically after adjustment for the different geriatric syndromes analyzed.
Conclusions. Charlson’s comorbidity was found to be an independent mortality predictor in elderly patients with advanced chronic kidney disease. Dialysis did not improve survival with respect to conservative treatment in patients with Charlson higher than 8 points.
