Effects of a protocol-based management of type A aortic dissections

BackgroundAscending aortic dissections (AADs) require prompt diagnosis and surgical treatment. We present the results of implementing a multidisciplinary aortic dissection protocol on the outcomes of AAD treatment at a nonteaching hospital.MethodsFrom January 2002–December 2013, 54 patients with the diagnosis of AAD were treated at our institution. Thirty-seven (68.5%) were male with a mean age of 62.3 y. Cardiogenic shock was present in 25.9% of patients. An AAD protocol, focused on educating physicians on presenting signs and symptoms, adequate triaging, and the need for immediate surgical intervention, was implemented, alongside the standardization of surgical treatment. We divided the cohort into two eras, based on AAD program's implementation in 2006, to better assess the impact of this protocol.ResultsPatients from the early era had significantly longer time from Emergency Department to the operating room, more postoperative occurrence of prolonged ventilation, and a longer postoperative hospital stay at 8.7 ± 8 versus 3.1 ± 2.6 h (P = 0.002), 63% versus 18% (P = 0.002), and 63% versus 18% (P = 0.002), respectively. The overall mortality for the cohort was 9.3%, decreasing from 12.5% before 2006 to 7.9% after 2006.ConclusionsThe implementation of a multidisciplinary aortic dissection protocol has resulted in faster diagnosis and transport of AAD cases from the emergency room to the operating room, improving outcomes. Our data support the concept that nonteaching institutions can deliver excellent care to patients with acute aortic emergencies.
