Follow-up Care in Acute Kidney Injury: Lost in Transition

Acute kidney injury (AKI) is an increasingly common condition that is associated with long-term health outcomes. Recent studies have demonstrated that AKI, particularly when severe or persistent, is associated with all-cause mortality, CKD, ESRD, cardiovascular events, and reduced quality of life. However, data from multiple health care systems indicate that most patients do not see a nephrologist, although 1 study has suggested patients with AKI requiring dialysis may benefit from doing so. These observations raise the greater questions of what are the elements of care that may improve outcomes in survivors of AKI and which survivors need to be seen. Potential opportunities to improve care include appropriate risk stratification, closer monitoring of kidney function, management of CKD complications, blood pressure control, medication reconciliation, and education. Nephrologists are in an ideal position to lead and advocate for outpatient care pathways for survivors of AKI. In this article, we review the evidence supporting patient follow-up after AKI, describe the current state of follow-up care, and examine strategies to improve long-term outcomes for this high-risk population.
