Renal outcomes following intravenous contrast administration in patients with acute kidney injury: a multi-site retrospective propensity-adjusted analysis.
The purpose of this retrospective study was to investigate the relationship between intravenous contrast media (CM) administration and persistent acute kidney injury (AKI) in patients with pre-existing AKI. The researchers used propensity-weighted and entropy-balanced observational cohort analysis of consecutive hospitalized patients aged 18 years or older who met the Kidney Disease Improving Global Outcomes (KDIGO) creatinine-based criteria for AKI upon arrival at one of three emergency departments between 7/ 2017 and 6/2021. Patients either received or did not receive intravenous CM. The analysis included 14,449 patient encounters, with 12.8% admitted to the intensive care unit (ICU). The study found that CM was administered in 18.4% of all encounters. AKI resolved before hospital discharge in 69.1% of cases. No association between intravenous CM administration and persistent AKI was found after unadjusted multivariable logistic regression modeling, propensity weighting, and entropy balancing. Similar results were obtained from sub-group analysis of patients admitted to the ICU. Initiation of dialysis within 180 days occurred in 5.4% of the cohort, with no observed association between CM administration and increased risk of dialysis within this timeframe.
