What happens to acutely ill patients with acute kidney injury requiring in-hospital dialysis after their acute admission? How many recover and how many require chronic dialysis? A Canadian study of 3769 such patients followed up for an average of 3 years demonstrated that the incidence rate for chronic dialysis was only 2.63 per 100 person years, and that all cause mortality compared with matched controls was unchanged.
