Chronic Kidney Disease in Older Adults. Consensus Statement of  Russian Association of  Gerontologists and Geriatricians, Scientific Society of  Nephrologists of  Russia and Eurasian Association of Therapists

The prevalence of  chronic kidney disease (CKD) increases with age, but CKD is  often underdiagnosed in  older adults and regarded as  age-related changes of  kidney function. Screening for CKD is  mandatory in  older adults and should include estimated glomerular filtration rate (eGFR) using both the CKD EPI creatinine-based formula and the albumin/creatinine ratio in a urine spot sample. In older adults the diagnostic criteria of CKD are the same as in younger subjects.  CKD is  associated with advanced ageing and requires careful assessment of  geriatric syndromes.  Renal function should be assessed at least annually, considering a rate of decline in eGFR greater than 1 ml/min/1.73 m² per year as significant. Older adults with CKD are characterized by high comorbidity; risk factors for CKD and geriatric syndromes overlap. CKD should be  considered among a  number of  comorbid conditions that increase the risk of  deterioration of  geriatric status and underline the need for multidisciplinary management based on a comprehensive geriatric assessment. Patients with eGFR <60 ml/min/1.73 m² should be considered at high risk for renal and extrarenal adverse drug effects. In these patients, inappropriate medications, supplements, and vitamins should be carefully identified and corrected using STOPP/START criteria. eGFR and estimated creatinine clearance should be  carefully monitored during treatment with drugs that can potentially affect renal function and/or the dose of which is adjusted based on renal function, as well as during acute illness or exacerbation of chronic conditions.
