Timeframe: Within 7 days of enrollment

Population: Analysis restricted to participants with an AKI Score ≥2 and those who were followed for the designated duration. There were 56 participants with an AKI Score ≥2 in the V/Q arm and 63 in the CT arm.

Among patients enrolled who had an AKI risk score evaluated and followed for the outcome of acute kidney injury. AKI risk Score: age ≥50 years (1 point), HIV (1 point), coronary artery disease (1 point), diastolic hypertension ≥100 mmHg (1 point), and glycosuria ≥250 mg/dL (2 points). Preliminary data indicated that a higher risk score was associated with a higher rate of kidney injury, but this was an unvalidated score. The lowest score possible is 0 and the highest score possible is 6.
