Contrast-enhanced Computed Tomography and Acute Kidney Injury

Plain-language summary
Rationale and objectives: Since 1930 it has been accepted that intravenous injection of io-dinated contrast agent as part of contrast-enhanced computed tomography (CE-CT) imaging can induce a contrast-associated acute kidney injury (CA-AKI). For the last 10 years, studies have investigated this iatrogenia. However, those works didn't concern French population and particularly patient hospitalised after emergency department (ED) visit.
This study as-sessed the CA-AKI incidence and factor risks in patients hospitalised after a CE-CT in ED.
This was a retrospective cohort observational study in the ED of the Beaujon University Hospital between October 31st 2019 to January 24th 2022.
Patients over 16 years old who presented to the emergency department and underwent an intravenous contrast-enhanced CT were eligible. To be included, patients were required to have at least two creatinine measurements: one taken within 24 hours before CT and a second measurement taken between 48 hours to the seventh day following the initial test. The CT examination had to be performed at Beaujon Hospital with the injection of iodinated contrast agents such as IOMERON® (iomeprol) or XENETIX® (iobitridol).

Inclusion Criteria:
* Patients over 16 years old who presented to the emergency department and underwent an intravenous contrast-enhanced CT were eligible. To be included, patients were required to have at least two creatinine measurements: one taken within 24 hours before CT and a sec-ond measurement taken between 48 hours to the seventh day following the initial test. The CT examination had to be performed at Beaujon Hospital with the injection of iodinated contrast agents such as IOMERON® (iomeprol) or XENETIX® (iobitridol).
Exclusion Criteria:
* Patients were excluded from the study if they did not have two creatinine measurements meeting the specified criteria. If multiple contrast-enhanced CT examinations were per-formed within a seven-day period for the same patient, only the first examination was in-cluded in the study, while subsequent scans were excluded.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
The primary outcome was the occurrence of CA-AKI defined as KDIGO (Kidney Disease Improval Global Outcomes) tage 1 or higher within seven days after contrast-enhanced CT.
