TORONTO, June 25, 2012 – The number of patients receiving acute dialysis after cardiac and vascular surgery has increased three-fold since 1995. In a new study, researchers at the Lawson Health Research Institute in London, Ontario and the Institute for Clinical Evaluative Sciences (ICES) show a significant increase in the complications of severe acute kidney injury (AKI) requiring dialysis after major elective surgery.
"Outcomes of patients treated with acute dialysis after surgery remain poor. Our results should prompt renewed efforts to develop and test interventions to prevent severe acute kidney injury and to lessen the high burden of death and end-stage renal disease after acute kidney injury has occurred," says Dr. Amit Garg, one of the lead authors on the study. Dr. Garg is a Scientist at the Lawson Health Research Institute and ICES, a kidney specialist at the London Health Sciences Centre, and a Professor of Medicine and Epidemiology at Western University.
The population-based study of Ontario patients between 1995 and 2009 found:
"The use of acute dialysis after cardiac and vascular surgery has increased substantially since 1995. Interventional studies to better prevent and treat peri-operative acute kidney injury are needed," says Dr. Nausheen Siddiqui.
