Risk factors for acute kidney injury in older adults with critical illness: a retrospective cohort study.

ABSTRACT:

Background

Risk for acute kidney injury (AKI) in older adults has not been evaluated systematically. We sought to delineate the determinants of risk for AKI in older compared with younger adults.

Study design

Retrospective analysis of patients hospitalized in July 2000 to September 2008.

Setting & participants

We identified all adult patients admitted to an intensive care unit (n=45,655) in a large tertiary-care university hospital system. We excluded patients receiving dialysis or a kidney transplant prior to hospital admission and patients with baseline creatinine levels ≥ 4mg/dL, liver transplantation, indeterminate AKI status, or unknown age, leaving 39,938 patients.

Predictor

We collected data for multiple susceptibilities and exposures, including age, sex
