Safe use of iodinated and XXXX -based contrast media in current practice in Japan: a questionnaire survey.

@entity1 @entity8 @entity740 @entity2287 @entity479
PURPOSE: To help establish consensus on the safe use of contrast media in Japan. MATERIALS AND METHODS: Questionnaires were sent to accredited teaching hospitals with radiology residency programs. RESULTS: The reply rate was 45.4  % (329/724). For @entity8 ( @entity8 ), chronic and acute @entity8 were considered a risk factor in 96.7 and 93.6  %, respectively, and dehydration in 73.9  %. As preventive actions, intravenous hydration (89.1  %) and reduction of iodinated contrast media dose (86.9  %) were commonly performed. For @entity740 were considered risk factors in 98.5 and 90.6  %, respectively, but use of unstable @entity2287 -based contrast media was considered a risk factor in only 55.6  %. A renal function test was always (63.5  % in iodinated; 65.7  % in @entity2287 ) or almost always (23.1; 19.8  %) performed, and estimated glomerular filtration rate (eGFR) was the parameter most frequently used (80.8; 82.6  %). For the @entity1 with risk factors for acute adverse reaction (AAR), @entity479 premedication or/and change of contrast medium were frequent preventive actions, but intravenous @entity479 administration immediately before contrast media use was still performed. CONCLUSION: Our questionnaire survey revealed that preventive actions against @entity8 were properly performed based on @entity1 ' eGFR. Preventive actions against NSF and AAR still lacked consensus.
