AbstractAortic dissection is a lethal cardiovascular emergency that continues to pose a diagnostic dilemma to the emergency physician. The condition is rare, can present atypically and is associated with a cumulative mortality for every hour that passes. While it is a recognised differential of acute chest pain, its prevalence in comparison to other causes often leads to the diagnosis being overlooked. The ED is a busy environment with high patient turnover and varying degrees of complexity and acuity. This increases susceptibility to cognitive bias and error-producing conditions that can lead to delayed or missed diagnosis. In reported cases where aortic dissection has been missed, clinician awareness of the disease was not the primary issue but failure to respond to clinical cues suggestive of aortic dissection was. To improve patient outcomes for this condition, it is important for clinicians to be aware of pertinent cognitive bias and error-producing conditions.© 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.
