Economic Impact of Acute Kidney Failure
Determining the cost of an acute disease is complex. Intensive care unit (ICU) stay is a major driver of costs, and averages US $3,500 per day. Studies evaluating the costs of acute kidney injury (AKI) used widely different methods. Different AKI definitions and patient populations were some of the most notable differences in methods between studies. AKI patients generate costs that can be twofold to threefold higher than matched ICU patients not developing AKI. Renal replacement therapy and ICU length of stay are important drivers of costs of AKI patients. Patients with even small increases in serum creatinine have higher hospital and ICU costs compared with patients with no increases in serum creatinine. Therapies that prevent and/or effectively treat AKI can have substantial effects on hospital costs.
