The growth of AKI: half empty or half full, it's the size of the glass that matters.

Previous data suggest rapid growth in the population incidence of acute kidney injury (AKI). In this study, Kashani et al. report data from the Mayo Clinic Hospital indicating slowing to stabilization of AKI rates in Olmsted County, Minnesota, from 2006 through 2014. More studies are needed to confirm this trend, and if this trend exists, reasons behind it. Further, strategies to optimally care for vulnerable populations in which AKI rates remain high, including the elderly, are warranted.
