Impact of the Characteristics of Acute Renal Failure in Intensive Care on the Long-term Renal Prognosis: Prospective Multicenter Cohort Study

The purpose of this study is to assess the impact of Acute Kidney Injury (AKI) characteristics on long-term renal prognosis in Intensive Care Unit (ICU) patients.

This study will be a multicentre prospective observational study. The MAKE evaluation after different kind of Acute Kidney Injury (MAKI) study will be conducted in 4 Intensive Care Units (ICU) in Clermont-Ferrand, France.

An information form about the study will be given to each ICU patients hospitalized more than 24 hours. This form will be given to their support person if it is not possible. Data during ICU stay related to renal function of patients included in the study will be collected. If available data related to their baseline kidney function (before ICU hospitalisation) will be collected.

The patients will be classified into 3 groups based on the occurrence of AKI and its duration: 1) patients without AKI during their stay, 2) patients who had a transient AKI episode (defined as recovery within 48 hours of onset), and 3) patients who had a persistent AKI episode during their stay.

Inclusion Criteria:

• Patients who are hospitalized for more than 24 hours in ICU will be eligible to participate in the study.

Exclusion Criteria:

• patients who are younger than 18 years,
• those who are pregnant,
• those who have chronic extrarenal epuration before their admission to the ICU,
• those who are admitted for kidney transplantation,
• those under the safeguard of justice, and those who refuse to participate in the study.
