Public Awareness of Interventional Radiology: Population-Based Analysis of the Current State of and Pathways for...

To evaluate the awareness of interventional radiology (IR) among the public and identify methods for improvement.

Participants (N = 1,000) were anonymously surveyed using Amazon's Mechanical Turk crowdsourcing platform about medical and IR-specific knowledge, preferred methods of acquisition of medical information, and suggestions for improving awareness of IR. The survey consisted of 69 questions, including both Likert Scale and free text questions.

Of the participants, 92% preferred undergoing a minimally invasive procedure over surgery. However, 39.8% recognized IR as a medical specialty, and less than 50% of these participants correctly identified IR as procedurally oriented. Of those who discussed or underwent an IR procedure (n = 113), most were also offered to undergo the procedure performed by a surgeon (n = 66). Furthermore, 71% (n = 20) of those who underwent the procedure performed by a surgeon reported that lack of awareness of IR played a role in their decision. Almost half of the respondents (n = 458) were interested in learning more about IR, particularly the diseases treated and procedures performed (42% and 37%, respectively). Short (<10-minute) educational videos and increased patient education by primary care providers (PCPs) were among the most suggested ways to improve awareness. Regarding the ambiguity of the name "interventional radiology," most respondents (n = 555) reported this to be true, and "minimally invasive radiologist" was the most preferred alternative (21.18%).

Lack of awareness of IR may underlie underutilization. When presented with the knowledge that IR improves patient outcomes, minimally invasive procedures by an interventional radiologist are more often desired by the public than surgical options. Educational videos and patient education by PCPs may increase awareness of IR.
