AbstractThe incidence rate of AKI is increasing across the spectrum of hospitalized children and adults. Given the increased morbidity and mortality associated with AKI, significant research effort has been appropriately focused on standardizing AKI definitions, identifying risk factors, and discovering and validating novel, earlier structural biomarkers of kidney injury. In addition, a growing body of evidence demonstrates that AKI is a risk factor for the future development or accelerated progression of CKD. Unfortunately, prospective observational studies have not consistently followed survivors of episodes of AKI for longitudinal outcomes after hospital discharge, which could lead to ascertainment bias in terms of over- or underestimation of CKD development. Furthermore, data show that clinical follow-up of AKI survivors is low. This lack of systematic study and clinical follow-up represents a potential missed opportunity to prevent chronic disease after an acute illness and improve outcomes. Therefore, prospective study of transitions of care after episodes of AKI is needed to identify which patients are at risk for CKD development and to optimally target therapeutic interventions.
