Operative death does not account for all deaths attributable to transfer. We sought to determine the impact of transfer on mortality for all patients transferred with acute aortic dissections.<\/p>\n<p><strong>Methods<\/strong> \u2014 A retrospective study of de-identified health data between April 2003 and March 2020 for Ontario, Canada (14.7 million population) was performed to identify all patients hospitalized with acute aortic dissections. Non-transfers and interhospital transfers were reviewed and characteristics associated with transfer assessed. Associations between transfer and death were estimated using modified Poisson regression.<\/p>\n<p><strong>Results<\/strong> \u2014 There were 6,218 acute aortic dissections (type A, n=2,641; type B, n=3,577). For 148 hospitals, 11 had onsite cardiac surgery. There was a 2.02-fold (95% CI 1.66 &#8211; 2.45) increased risk of mortality for type A dissection patients transferred to a cardiac surgery hospital for surgical consideration (32.6%), relative to those at a cardiac surgery hospital who had surgery (16.3%). For patients that transferred alive and had surgery, there was no mortality difference (18.1% vs. 16.3%, p=0.37). A nontransfer palliation strategy was more likely for females (p&lt;.001), age &gt;75 (p&lt;.001), rural residence (p&lt;.008), and increased Charlson index (p&lt;.001). Type B dissections showed no difference in mortality across non-cardiac and tertiary hospitals (9.8% vs. 10.2%, p=0.70).<\/p>\n<p><strong>Conclusions<\/strong> \u2014 Transfers for acute type A dissections were associated with increased mortality. Palliation instead of transfer for surgical consideration was more common for women.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Background \u2014 There is a time-sensitive increase to mortality for acute type A dissections, yet interhospital transfer has not shown to increase operative death.
