Significance Statement

Dialysis-requiring AKI (AKI-D) now accounts for more than 15% of outpatient hemodialysis initiations; over 30% of these patients with AKI-D may have potential to recover. However, little is known about strategies currently used to treat outpatient AKI-D and screen for recovery. In this study of 1754 patients with AKI-D, we found that (1) the initial dialysis orders were similar to those of patients with contemporary incident ESKD, despite different treatment goals; (2) timed urine collections were completed in only a minority of patients; and (3) most patients with AKI-D who recovered discontinued dialysis without ever having been weaned from their initial dialysis prescription, suggesting there may be substantial opportunity to wean dialysis sooner.
