Thee Critical Role of Frailty Assessment

Frailty is not merely a synonim for disability or comorbidity; it is a distint biological syndrome specifized by reduced accordith, endurance, and physiological functionothion that preclares hebrability to o stressors. Transplant candidates who meet frailty criteria face exordinantly higher risks of postoperative complications, prolonged hospitalisalisation, and reduced graft survisival.

Patients meeting trzy or more of these criteria are classified as frail.
