Do patients undergoing intravenous contrast-enhanced computed tomography experience increased incidence of acute kidney injury?

BEEM Bottom Line

Why is this study important?

Emergency department (ED) patients often require critical, time-sensitive, intravenous (IV) contrast-enhanced computed tomography (CT), but the greatest concern is the risk of acute kidney injury (AKI), especially in those with renal insufficiency. Undue concerns about AKI might delay contrast CT or lead the clinician to choose other, less accurate imaging.

Which, if any, threats to validity are most likely to have an impact on the results and how?
