Contrast-associated acute kidney injury (CA-AKI) according to the type and dose of contrast in contrast-enhanced radiographic examinations. preliminay results of the nefrocon study

Materials and Methods Prospective multicenter-study in 34 Spanish ICUs covering a 4-month period (from December 15th, 2012 to March 15th, 2013). Research endorsed by the Spanish Society of Intensive, Critical and Emergency Care Medicine (SEMICYUC). From 1035 initial cases, exclusion criteria of uncompleted demography data and renal depuration yielded a final total of 1012 patients. CA-AKI is defined as an absolute increase of 0.5mg/dl or 50% relative increase of serum creatinine 48-72 hours after contrast administration. Statistical analysis through multiple logistic regression with CA-AKI as dependent variable performed with software R3.1.2 for OsX. Included variables comprise those with p < 0.1 in univariant tests and those related to CA-AKI in literature. Results are expressed as average (standard error).
