Aim: To characterise the current landscape of informed consent practices for image-guided procedures, including location of consent, guideline availability, and utility of decision-aid resources.

Materials And Methods: A survey of 159 interventional radiologists was conducted from April through June 2022. The survey evaluated participant demographics (gender, practice type, and level of training) and consent practices. Fifteen questions investigated discussion of benefits, risks, and alternatives, who obtained consent, location of consent conversations, how decision-making capacity is assessed, availability of formal guidance on consent discussions, and if and how decision-aids are used.

Results: Most respondents (93.7%) were "extremely" or "very" comfortable discussing the benefits and risks of image-guided procedures during informed consent. Most respondents were "very" comfortable discussing alternative treatments within radiology (86.8%) while fewer felt confident regarding alternatives outside radiology (46.5%). Most respondents indicated obtaining consent in a pre-procedure area (89.9%), while 12.7% of respondents obtained consent in the procedure room. Of the respondents, 66.7% did not have formal education or documented guidance on what providers should disclose during consent. Ninety-two respondents (57.9%) reported using decision aids. The type of decision aid varied, with most reporting using illustrations or drawings (46.6%). Decision aid utility was more prevalent in non-teaching/academic (71.4%) versus academic (61%) institutions (p=0.02).

Conclusion: Regardless of demographics, interventionalists are confident in discussing benefits, risks, and alternative image-guided therapies, but are less confident discussing alternative treatment options outside of radiology. Formal education on informed consent is less common, and the use of decision aids varies between teaching and non-teaching institutions.
