Brief Summary:

The evaluation of an accurate occurrence rate for AKI is of great importance for health policy, quality initiatives as well as for designing clinical trials.

The primary objective is to prospectively evaluate the incidence of AKI within 72 h after extended surgical procedures that require admission to an observation unit.


Condition or disease
Acute Kidney Injury (AKI)

Detailed Description:

Acute kidney injury (AKI) is a severe clinical complication with increasing incidence and is associated with adverse short- and long-term outcomes resulting in a major health care burden worldwide. The introduction of consensus classification systems has enhanced the awareness for AKI. The evaluation of an accurate occurrence rate for AKI is of great importance for health policy, quality initiatives as well as for designing clinical trials. However, analyzing AKI from existing databases is often limited by missing data elements, especially the inclusion of the urine output criteria. Missing data and the use of different definitions before the consensus classification are the reasons for large variations in reported occurrences of surgical induced AKI.

The primary objective is to prospectively evaluate the incidence of AKI within 72 h after extended surgical procedures that require admission to an observation unit (e.g., ICU, IMC, PACU) using the latest consensus definition for AKI (Kidney Disease: Improving Global Outcomes criteria) and a standardized data collection instrument and to assess the dependence of AKI on preoperative and intraoperative factors.

Method: International prospective, observational, multi-center, cross-sectional cohort study

Eligible patients will be identified during preoperative assessment. All eligible patients will be approached to obtain written consent.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence of Acute Kidney Injury [ Time Frame: 72 hours after extended surgery ]
    Occurrence of acute kidney injury according to the KDIGO (Kidney Disease: Improving Global Outcomes) criteria


Secondary Outcome Measures :
  1. Severity of acute kidney injury (number of patients with KDIGO stage 1, KDIGO stage 2 or KDIGO stage 3) [ Time Frame: 72 hours after extended surgery ]
    Definition and classification of acute injury according to the KDIGO (Kidney Disease: Improving Global Outcomes) clinical practice guidelines on acute kidney injury

  2. Number of patients with renal replacement therapy [ Time Frame: up to 90 days after extended surgery ]
  3. Mortality [ Time Frame: up to 90 days after extended surgery ]
  4. Hospital stay [ Time Frame: up to 90 days after extended surgery (until discharge) ]
  5. Intensive Care Unit stay [ Time Frame: up to 90 days after extended surgery (until discharge) ]
  6. MAKE (major adverse kidney events) [ Time Frame: up to 90 days after extended surgery ]
    combined endpoint consisting of mortality, renal replacement therapy, persistent renal dysfunction defined as serum-creatinine >= 1.5 times as compared to baseline serum-creatinine
