Hemodialysis Initiation in Oldest-Old Patients: A Case Series

With an increase in the number of older adults worldwide, the oldest-old population, defined as individuals over the age of 90, is also growing. Japan is now facing the problem of a "super-aged society" in which over 21% of the population is aged over 65. The oldest-old constituted 1.8% (2.31 million) of the Japanese population in 2019. Such individuals have special health-care needs. In cases of acute or chronic (or both) renal failure in the oldest-old, it becomes difficult to decide whether dialysis should be initiated. The issue is controversial, and there is some debate on whether dialysis should be avoided in elderly people because of their frailty or if it should be initiated to enable them to spend their remaining years with their families by improving their quality of life. Herein, we describe our experience in 4 cases of hemodialysis initiated in patients over the age of 90. In our experience, dialysis enabled them to spend the rest of their lives with their families, which could not have been possible without it. Although further studies are needed, we concluded that oldest-old individuals in good general health could be eligible for and benefit from hemodialysis. (C) 2021 The Author(s). Published by S.
