  Definition of Frailty Top


Frailty is a condition of increased vulnerability to physical stressors as a result of accumulation of multiple deficits across various systems. It is characterized by diminished strength, endurance, and reducedphysiologic function.[1]


  Causes of Frailty Top


There are numerous contributing factorsto the development of frailty including chronic disease, physiological perturbations, and psychosocial impairment. Sarcopenia, aprogressive decline in muscle mass as a result of the aging process, and dynapenia, loss of strength with aging, are believed to be precursors to frailty.[2] In the chronic kidney disease (CKD) population, frailty is associated with sarcopenia, dynapenia, protein energy wasting (loss of somatic and circulating protein and energy reserves) and other CKD complications.[3] Prevalence of this syndrome is much higher in CKD than in the general population and increases with decliningrenal function.[4]


  Clinical Implications of Frailty in CKD Top


Frailty is associated with impaired physical performance, disability, reduced quality of life, and increased hospitalization and mortality rates. Diminished intakes of dietary protein and energy contribute to sarcopenia and protein energy wasting, further leading to frailty.


  Identification of Frailty Top


Although no consensus on the operational definition and methods for identification havebeen established, several tools to assess frailty are available. The Fried Phenotype Model defines those with frailty as meeting three out of five criteria: (1) low grip strength, (2) self-reported exhaustion, (3) slowed walking speed,(4) low physical activity, (5) and unintentional weight loss.[5] A Frailty Index score, calculated by totaling the number of deficits from a broad range of medical and psychological conditions, is another predictive model; however, it is time-consuming to conduct. Clinical Frailty Scales (CFS), which rely solely on judgement, are more widely used in the clinical setting as screening tools.[6],[7] Although not an exhaustive list, these screening tools can be used by cliniciansto identify high risk patients.


  Prevention of Frailty Top


Currently there are no established interventions for the prevention and treatment of frailty. An interdisciplinary approach which includes nutritional, cognitive, and physical intervention may attenuate the morbidity associated with frailty. Nutritional interventions include identificationof possible causes for reduced appetite, initiation of oral supplementation, correction of metabolic acidosis, optimal fluid management, incorporation of resistance exercise, and promotion of adequate vitamin D status.
