Students’ perspectives regarding the administration of contrast agent for enhanced CT examination of septic patients with additional medical conditions. In 75% (n = 79/105), students rated a “known severe allergic reaction to contrast media” as an absolute contraindication to its administration. While 15% (n = 16/105) of participants reported no contraindication, 42% (n = 44/105) considered a terminal renal insufficiency in a septic patient an absolute contraindication to iodine-based contrast agent administration. For manifest hyperthyroidism, students ticked “no CI,” “relative CI,” and “applicable with preparation” in about 1/3 each, while only 1% (n = 1/105) of participants considered it as no contraindication for contrast-enhanced CT. In contrast, 12% (n = 13/105) of students saw no contraindication to contrast administration in septic patients with latent hyperthyroidism. Moreover, students did not once tick absolute CI for latent hyperthyroidism. Total n = 105; missing responses in 8 participants. CT, computed tomography; eGFR, estimated glomerular filtration rate; CI, contraindication. *Preparation = prophylaxis (including hydration and/or medication) or lower dose of contrast agent
