Assessing risk factors in adults having iodine-based contrast media
NICE ()
1.1.5Before offering iodine-based contrast media to adults for non‑emergency imaging, investigate for chronic kidney disease by measuring eGFR or by checking an eGFR result obtained within the past 3 months. [2013]
1.1.6Before offering iodine-based contrast media to adults, assess their risk of acute kidney injury but do not delay emergency imaging. Be aware that increased risk is associated with:
chronic kidney disease (adults with an eGFR less than 40 ml/min/1.73 m2 are at particular risk)
diabetes but only with chronic kidney disease (adults with an eGFR less than 40 ml/min/1.73 m2 are at particular risk)
heart failure
renal transplant
age 75 years or over
hypovolaemia
increasing volume of contrast agent
intra-arterial administration of contrast medium with first-pass renal exposure. [2013]
1.1.7Include the risks of developing acute kidney injury in the routine discussion of risks and benefits of the imaging procedure. Follow the recommendations on shared decision making in the NICE guideline on patient experience in adult NHS services. [2013]
