Review Meta Analysis
Acute kidney injury and prognosis after cardiopulmonary bypass: a meta-analysis of cohort studies.
Robust estimates and sources of variation in risks of clinical outcomes for cardiopulmonary bypass (CPB)-associated acute kidney injury (AKI) are needed to inform clinical practice and policy. We aimed to assess whether the methods for defining acute kidney disease modify the estimated association of AKI with CPB. ⋯ CPB-associated AKI is associated with a more than 2-fold increase in early mortality regardless of AKI definition.
