Summary
Informed consent for intravenous contrast material is common, with about two-thirds of physicians obtaining it. However, practice varies by specialty and practice size.
Area of Science:
- Radiology
- Medical Ethics
Background:
- Informed consent for intravenous contrast material administration is a debated topic.
- It involves disclosing risks and obtaining patient permission.
Purpose of the Study:
- To survey the practice of obtaining informed consent before intravenous contrast material administration.
- To identify factors influencing the use of informed consent.
Main Methods:
- A survey was distributed to physician groups billing Pennsylvania Blue Shield for contrast-enhanced procedures in 1989.
- Physician groups were categorized by specialty, hospital size, group size, and practice type.
Main Results:
- Approximately two-thirds of physician groups reported obtaining informed consent for contrast material, regardless of type (ionic/nonionic).
- Nonradiologists were more likely than radiologists to obtain consent for ionic contrast material.
- Practices in larger hospitals or larger physician groups, and university-affiliated practices, were less likely to obtain informed consent.
Conclusions:
- Informed consent for intravenous contrast material is a prevalent practice.
- Factors such as physician specialty and practice setting influence the utilization of informed consent.
