Automated Prediction and Prevention of Contrast Induced Nephropathy After Cardiac Catheterization

Contrast agent is typically used during routine cardiac intervention in order to enhance the imaging necessary to perform the procedure. Using this contrast agent could lead to kidney injury, called contrast induced nephropathy (CIN). Currently, the methods used to reduce the risk of CIN include reducing the amount of contrast agent used and using a hydration strategy during procedure. A computer-based risk tool has been developed which reports a risk score for the likelihood a person undergoing cardiac intervention gets CIN and a proposed corresponding hydration strategy to reduce the risk of CIN. The purpose of this study is to determine whether the rate of CIN decreases when the treating physician has access to this risk tool during the procedure.
