Assessing the Risk of Contrast-Induced Nephropathy Using a Finger Stick Analysis in Recalls from Breast Screening:...

Area of Science:

• Radiology
• Nephrology
• Medical Devices

Background:

• Contrast-induced nephropathy (CIN) is a risk associated with iodine-based contrast media.
• Accurate risk assessment is crucial for patient safety before contrast-enhanced procedures.

Purpose of the Study:

• To evaluate a handheld point-of-care (POC) device for predicting CIN risk.
• To assess the device's ability to discriminate patients at risk before contrast delivery.

Main Methods:

• 351 patients undergoing contrast-enhanced spectral mammography (CESM) were assessed.
• A POC device (StatSensor CREAT) and risk questionnaire were used.
• POC results were compared to laboratory creatinine testing.

Main Results:

• The POC device failed to correctly categorize 86% of patients identified as high-risk by laboratory testing.
• Two patients developed self-limiting CIN.
• The device did not reliably assess renal function impairment.

Conclusions:

• The tested POC device is not reliable for assessing renal function in patients undergoing CESM.
• Standard clinical laboratory testing is preferred for CIN risk assessment.
