ObjectiveTo retrospectively assess the accuracy and inter-rater reliability of the aortic dissection detection risk score (ADD-RS).MethodsSingle-centre, observational, diagnostic accuracy study undertaken in a university-affiliated, tertiary hospital ED.ResultsTwo hundred patients were enrolled. Five patients were diagnosed with acute aortic dissection and had an elevated ADD-RS >0. The ADD-RS was 100% sensitive with a negative and positive predictive values of 100% (if ADD-RS ≥1). Inter-rater reliability was moderate (Kappa = 0.55).ConclusionThe ADD-RS was highly sensitive in our cohort. Further work to evaluate the score prospectively and in combination with a D-Dimer is required.© 2018 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.
