CT Policy Regarding Contrast-Associated Acute Kidney Injury
If the departmental outpatient questionnaire identifies risk for kidney disease, then a Point-of-Care (POC) Creatinine/eGFR test will be performed at the time of the contrast enhanced CT study if no eGFR value within 6 weeks is available. If no risk factors are identified on out-patient screening form, no renal function testing is needed.
For ED and In-Patients
All patients should have eGFR value available within 48 hours of test before receiving IV contrast. If none is available than labs (POC testing is adequate) should be obtained before the contrast enhanced CT is performed.
If eGFR value is greater than 30 the patient can receive IV iodinated contrast. If eGFR is less than or equal to 30 the case will need approval by the radiologist before IV contrast is used to minimize risk of contrast related AKI.
