Identification of AKI sub-phenotypes based on trajectory of serum creatinine

ICU patients included in the ASSESS-AKI study will be evaluated and identified for AKI sub-phenotypes based on the trajectory of serum creatinine. In addition, the association of AKI sub-phenotypes with long-term outcomes such as incidence and progression of chronic kidney disease and need for renal replacement therapy will be identified. The goal is to develop a more accurate and real-time risk stratifying tool to identify patients at increased risk for poor long-term outcomes after development of AKI in the ICU.
