Use of informed consent for ionic and nonionic contrast media.
The use of informed consent before intravenous administration of contrast material remains a controversial issue. It involves explaining the risks of intravenous contrast material and obtaining the patient's permission for its use. All physician groups who had billed Pennsylvania Blue Shield for at least three intravenous contrast material-enhanced procedures performed in 1989 were surveyed. Informed consent was obtained from at least some patients by about two-thirds of physician groups before using intravenous contrast material, regardless of whether it was ionic or nonionic. Nonradiologists were more likely to obtain informed consent before the use of ionic contrast material than radiologists. Regardless of specialty, practices associated with larger hospitals (greater than 250 beds), larger physician groups (greater than 10), or a university used informed consent less often than smaller physician groups or those associated with a smaller hospital or a private practice. Though results may be affected by regional variation or increased usage since previous surveys, the use of informed consent before the intravenous injection of contrast material is a common practice; it is obtained in the majority of patients.
