Background and study aims
Though acute kidney injury (AKI) [kidneys suddenly (acute) become unable to do the work expected of them] is extremely common, the knowledge about this disease in the perioperative phase (at or around the time of operation) is very poor. This study aims to understand the interfering factors and predictors of renal function in the perioperative setting (within 48 h postoperatively) after moderate to high-risk surgery in both patients with normal or already preoperatively compromised renal function. Independent predictor for acute kidney injury (AKI) and incidence of AKI in the perioperative setting will be determined. Finally, different types of surgery will be assessed and the relationship between occurrence of AKI and the type of surgery will be assessed. The findings of this study will be used in the improvement and quality program in University Hospital Brussels.

Who can participate?
All patients who underwent a moderate to high-risk surgery in one year will be included in this study.

What does the study involve?
Preoperative and postoperative renal function data, mortality after 30 days after surgery and length of stay in the hospital will be assessed. The association between preoperative patient characteristics and AKI will be assessed. Independent risk factors to develop AKI and on mortality will be determined. Finally, those patients with chronic kidney disease will be analysed separately to determine independent predictors to develop worsening kidney function.

What are the possible benefits and risks of participating?
As this is an observational study, there is no risk.

Where is the study run from?
The study is run from the University Hospital, department of Anesthesiology and Perioperative Medicine in Brussels.

When is the study starting and how long is it expected to run for?
The study started in June 2013 and is expected to last till September 2013.

Who is funding the study?
University Hospital Brussels (Belgium) - Department of Anaesthesiology and Perioperative Medicine

Participant information sheet No patient information sheet, as this study is retrospective and observational. The ethics committee waived the use of a patient information sheet.
Scientific titleIncidence and outcome of perioperative renal failure after moderate and severe surgery
Study objectivesRetrospectively, incidence of perioperative renal failure in moderate or high risk surgical procedures will be assessed, in addition in those patients with diminished renal function, postoperative renal failure will noted and registered.
Ethics approval(s)Ethics Committee University Hospital Brussels, Approval date: 22/12/2011, ref: 2011/282
Health condition(s) or problem(s) studiedRenal failure, postoperative outcome
InterventionThe observational study concerns the occurrence rate of renal failure preoperatively and postoperatively. The purpose is to come to a risk score in our hospital. Therefore we need a large population (we deliberately took one year of patients) and variables such as preoperative status (cardiac, respiratory, renal) as well as the same variables on postoperative day (POD) 1 and 30 day mortality and length of stay in the hospital.
Intervention typeOther
Primary outcome measure30 day mortality
Secondary outcome measures1. Renal function at discharge. The renal function will be assessed according to the RIFLE criteria:
Risk: increase of the serum creatinine x1.5GFR or drop down >25%
Injury: increase of the serum creatinine x2GFR or drop down >50%
Failure: increase of the serum creatininex3 GFR or drop down >75%
Loss: total loss of kidney function for more than 4 weeks
ESDR: complete loss of kidney function, need for dialysis
2. Need for postoperative supportive measures
