Surgeon education on intraoperative do not resuscitate (DNR) orders is crucial for enhancing patient care and respecting autonomy.

• 56.5% of surgery residents mistakenly thought DNR status must be revoked for elective surgeries; 52.1% believed this for emergencies.
• A simulation-based curriculum significantly boosted residents’ confidence (p < .001) and corrected misconceptions regarding DNR status preservation (p < .01).

Implementing this training can lead to better communication and decision-making around DNR orders, ultimately improving surgical outcomes.
