Impact of an emergency department bypass referral pathway for surgically managed Type A aortic dissection diagnosed at non-aortic centers

Objective: (DBP) in April 2019. This 24/7 pathway allows patients diagnosed with acute aortic syndrome at non-aortic centers to bypass the emergency department (ED) and proceed directly to surgical care. This study evaluates the impact of the DBP on surgical outcomes for TAAD patients diagnosed at non-aortic centers. Methods: We retrospectively analyzed medical records of TAAD patients diagnosed at non-aortic centers and transferred to our hospital for surgery between January 2018 and December 2023. Clinical outcomes before and after DBP implementation were compared. Results: = 0.002, hazard ratio = 4.546, 95% CI: 1.721-12.004). Conclusion: A coordinated, point-to-point referral model between the Chest Pain Center and the Aortic Center integrating streamlined pre-hospital triage and a dedicated aortic surgical team significantly improves outcomes for TAAD patients diagnosed at non-aortic centers.
