Frailty in Patients With Chronic Kidney Disease Stage Five

Aim To study the prevalence of frailty in patients with chronic kidney disease stage 5 (CKD5) and to assess coexisting factors associated with frailty in chronic kidney disease. Patients and methods We studied the prevalence of frailty in CKD5 patients from November 2021 to November 2022. CKD5 patients over 18 years of age were included. Patients on maintenance hemodialysis and CKD5 patients on pre-dialysis care were included. Patients with active infection and significant morbidity were excluded. We performed a history and clinical examination and recorded laboratory data. We performed frailty assessments using modified Fried's criteria. Frailty was defined based on previously validated Fried's criteria, which included 1. Slowness, 2. Weakness, 3. Unintentional weight loss, 4. Exhaustion, 5. Low physical activity. A patient is considered frail if three or more components are present. We evaluated the prevalence of frailty in pre-dialysis and dialysis care participants and the association of frailty with coexisting factors. Results Of the 139 patients, 84 were on thrice-weekly hemodialysis, and 55 were on pre-dialysis care. We found the prevalence of frailty to be 41%. The prevalence of frailty was similar in patients on pre-dialysis care and hemodialysis. The prevalence of frailty in hemodialysis patients and those in pre-dialysis care was 43% and 40%, respectively. The prevalence of frailty among the elderly (over 55) was 82%. The prevalence of frailty among diabetes patients was 75%. Factors with a statistically significant association with frailty included old age (p < 0.005), native kidney disease (p < 0.005), edema (p < 0.001), intradialytic hypotension (p = 0.002), and various comorbidities like diabetes (p < 0.001), heart failure (p < 0.001), coronary artery disease (p = 0.001), and cerebrovascular accidents (p = 0.016). We observed no significant association with the duration of chronic kidney disease (CKD) (p = 0.458), duration of dialysis (p = 0.838), or body mass index (BMI) (p = 0.267). The most commonly reported frailty components were exhaustion (61.9%), low physical activity (61.2%), and weak handgrip (55.4%). Conclusion Frailty is a marker of increased vulnerability to adverse outcomes. A significant proportion, 41% of CKD5 patients, are frail. Dialysis does not affect the prevalence of frailty in CKD5 patients. Old age, native kidney disease, edema, intradialytic hypotension, and comorbidities like diabetes, heart failure, coronary artery disease, and cerebrovascular accident are significantly associated with frailty in CKD5 patients. CKD patients with those conditions should receive special care to reduce the development of frailty.
