Acute Kidney Injury Requiring Dialysis: Outcomes

Abstract

Introduction: Acute kidney injury (AKI) requiring dialysis (AKI-D) carries high morbidity and mortality. Methods: Systematic review of 30 cohort studies (n=25,000) examining short- and long-term outcomes of AKI-D survivors. Results: In-hospital mortality was 40–60%. Among survivors, 20–30% remained dialysis-dependent at 90 days. One-year mortality after discharge was 30%. Chronic kidney disease developed in 50% of renal recovery patients. Discussion: AKI-D accelerates cardiovascular events and hospital readmissions. Conclusion: AKI-D survivors require long-term nephrology follow-up for CKD surveillance.
