Brief Summary:
The primary objective is to safely determine if the investigators can identify the severity of Acute Kidney Injury (AKI) early in the course of the disease. Once enrolled the investigators will draw blood and urine for novel and standard biomarkers. The investigators are attempting to determine if these biomarkers can forecast the course of AKI (need for dialysis, death and renal recovery). The investigators seek to determine how well physicians caring for those with AKI can predict the clinical course compared to these novel biomarkers of AKI and if there is an association between clinical course and 3 year patient outcomes.

Condition or disease Intervention/treatment Phase
Acute Kidney Failure Drug: Furosemide Not Applicable

Detailed Description:
AKI is a very common disease in the setting of critical illness and carries an extremely high morbidity and mortality rate (over 50%). Currently there are no FDA approved therapuetic agents for the treatment of AKI. There is limited prospective evidence to guide nephrologists in terms of which patients will progress to more severe AKI in the setting of early AKI. Similarly, there is no evidence to guide nephrologists in terms of which patients will completely recover their renal function after AKI. Thus we need to know very early in the course of AKI which patients will progress and go on to require RRT. Additonally we will investigating the long term patient outcomes, 2-3 years after the index AKI admission.
