OBJECTIVE: @entity810 is common among hospitalized @entity1 and likely leads to inflated reports of the incidence of CT contrast agent-induced @entity8 as a cause of @entity810 . For a more accurate estimation, we compared the incidence of @entity810 immediately after contrast agent administration and a few days afterward in the same population. We also controlled for a @entity1011 level increase starting before and continuing after CT, which may be incorrectly associated with the scan itself. MATERIALS AND METHODS: After excluding @entity1 undergoing dialysis, we included all adults who underwent CT from January 2006 through May 2013 in our health region. The incidence of @entity810 ( @entity810 ) and dialysis after @entity810 were assessed in the immediate period (24-48 hours) and in a delayed period (72-96 hours) after the scan. New @entity810 in either period occurred if the @entity1011 level had increased at a greater rate than that in a preceding 24-hour interval. The incidence of @entity810 and dialysis after @entity810 attributable to CT were calculated by subtracting the delayed incidence from the immediate incidence. RESULTS: Incidences of @entity810 and dialysis after @entity810 attributable to contrast-enhanced CT were statistically insignificant across glomerular filtration rate (GFR) subgroups. @entity810 incidences ( @entity810 Network stage I or worse) were 0.5% (95% CI, -0.4% to 1.4%) for GFR greater than 60 mL/ @entity1009 .73 m(2), 2.4% (95% CI, -0.7% to 5.6%) for GFR 30-59 mL/ @entity1009 .73 m(2), -4.3% (95% CI, -19.8% to 11.3%) for GFR 15-29 mL/ @entity1009 .73 m(2), and 0% (95% CI, -24.5% to 24.5%) for GFR less than 15 mL/ @entity1009 .73 m(2). CONCLUSION: There appears to be a minimal risk of CT contrast agent-induced @entity8 at mild to moderate levels of @entity8 .
