RESUMO
The term frailty describes a complex syndrome of reduced resistance to stress factors as a consequence of age-related degeneration in various organ systems.In the general population frailty is associated with poor clinical outcomes, including an increased risk of falls, hospitalization, functional impairment and mortality. Frailty occurs earlier and its prevalence is higher in patients with chronic kidney disease (CKD) compared to the general population. Frail patients with CKD, on dialysis or not, have reduced quality of life and increased hospitalization and mortality rates, regardless of age, sex or comorbidities.The identification of frailty in patients with CKD can lead to the detection of important and potentially modifiable risk factors. Early nephrological evaluation coupled with an interdisciplinary approach including primary care physicians, geriatricians, physiotherapists, occupational therapists and nutritionists, is fundamental in the prevention of frailty as well as in the management of frail patients with CKD.Several instruments have been developed to screen for and assess the degree of frailty; however, there is currently no recommendation as to which should be used in nephrology and how to manage frail patients with CKD. In this article we suggest an approach based on a multidimensional, interdisciplinary evaluation aimed at the early identification and management of frail CKD patients independent of the clinical setting of admission; however, more important than the method used is the need to identify and follow-up on frail CKD patients.
