Assessment
Primary outcomes
The proportion of non-medical adults who are aware of the term "anesthesiologist" and their core professional roles

Results
Of 1,000 respondents, 418 (41.8%) had high recognition of anesthesiologists. Recognition was higher in women and increased with age. Recognition of intraoperative anesthesia was high (84.7%), whereas recognition of procedural sedation and analgesia, intensive care, and chronic pain management was low. Health interest and health literacy were not associated with recognition, but personal contacts and fictional works were.
