Abstract

Background and objectives Acute kidney injury (AKI) is a frequent complication in critically ill patients and sepsis is the most common contributing factor. We aimed to determine the risk factors associated with AKI development in patients with septic shock. Design, setting, participants, & measurements Observational cohort study consisted of consecutive adults with septic shock admitted to a medical intensive care unit (ICU) of a tertiary care academic hospital from July 2005 to September 2007. AKI was defined according to RIFLE criteria (urine output and creatinine criteria). Demographic, clinical, and treatment variables were reviewed. Main outcomes measured were AKI occurrence, all-cause hospital mortality, and hospital and ICU length of stay. Results Three hundred ninety patients met inclusion criteria, of which 237 (61%) developed AKI. AKI development was independently associated with delay to initiation of adequate antibiotics, intra-abdominal sepsis, blood product transfusion, use of angiotensin-converting enzyme inhibitor/angiotensin-receptor blocker, and body mass index (kg/m2). Higher baseline GFR and successful early goal directed resuscitation were associated with a decreased risk of AKI. Hospital mortality was significantly greater in patients who developed AKI (49 versus 34%). Conclusions In a contemporary cohort of patients with septic shock, both patient and health care delivery risk factors seemed to be important for AKI development.
