Background And ObjectivesWith aging of the general population, patients who enter dialysis therapy will more frequently have geriatric impairments and a considerable comorbidity burden. The most vulnerable among these patients might benefit from conservative therapy. Whether assessment of geriatric impairments would contribute to the decision-making process of dialysis initiation is unknown.Design, Setting, Participants, & MeasurementsA systematic Medline and Embase search was performed on December 1, 2015 to identify studies assessing the association between risk of mortality or hospitalization and one or more geriatric impairments at the start of dialysis therapy, including impairment of cognitive function, mood, performance status or (instrumental) activities of daily living, mobility (including falls), social environment, or nutritional status.ResultsTwenty-seven studies were identified that assessed one or more geriatric impairments with respect to prognosis. The quality of most studies was moderate. Only seven studies carried out an analysis of elderly patients (≥70 years old). Malnutrition and frailty were systematically assessed, and their relation with mortality was clear. In addition, cognitive impairment and functional outcomes at the initiation of dialysis were related to an increased mortality in most studies. However, not all studies applied systematic assessment tools, thereby potentially missing relevant impairment. None of the studies applied a geriatric assessment across multiple domains.ConclusionsGeriatric impairment across multiple domains at dialysis initiation is related to poor outcome. However, information in the elderly is sparse, and a systematic approach of multiple domains with respect to poor outcome has not been performed. Because a geriatric assessment has proved useful in predicting outcome in other medical fields, its potential role in the ESRD population should be the subject of future research.Copyright © 2016 by the American Society of Nephrology.
