Biomarker-guided Implementation of the AKI Bundle

Not Applicable
Completed
Conditions
Acute Kidney Injury (Nontraumatic)
Interventions
Other: Intervention
Registration Number
NCT03244514
Lead Sponsor
University Hospital Muenster
Brief Summary

There is no specific therapy for acute kidney injury. It is presumed that supportive measures improve the care and outcome of patients with acute kidney injury.

The investigators hypothesize that the implementation of a bundle of supportive measures adapted to patients undergoing cardiovascular surgery reduces the occurence of AKI.

A Randomized prospective multicenter trial is needed to investigate whether the implementation of the bundle of measures is effective to prevent AKI in high risk patients undergoing cardiac surgery. In this feasibility trial the investigators will analyze the compliance rate to the trial protocol in a multicenter, multinational cohort in preparation for a large randomized controlled trial.

Primary Outcome Measures
NameTimeMethod
Compliance rate48 hours after start of intervention

proportion of patients who are treated according to the trial protocol: CV surgery AKI bundle fulfilled at all time

Secondary Outcome Measures
NameTimeMethod
ICU and hospital stayup to 1 year after start of intervention (until discharge)
Number of patients with renal replacement therapy90 days after start of intervention
Free-days through of vasoactive medications and mechanical ventilation28 days after start of intervention
Renal recovery90 days after start of intervention

renal recovery is defined as serum creatinine levels \< 0.5 mg/dl higher than baseline serum creatinine (creatinine level before surgery)

Occurence of AKI72 hours after start of intervention
Moderate and severe AKI72 hours after start of intervention
Mortality90 days after start of intervention
