Objective:
To retrospectively assess the accuracy and inter-rater reliability of the aortic dissection detection risk score (ADD-RS).
Methods:
Single-centre, observational, diagnostic accuracy study undertaken in a university-affiliated, tertiary hospital ED.
Results:
Two 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).
Conclusion:
The ADD-RS was highly sensitive in our cohort. Further work to evaluate the score prospectively and in combination with a D-Dimer is required.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
