Figure 1. The elements of an assessment of anaphylaxis according to Brighton as implemented in AERO.

Performing a diagnosis involves assessing a number of criteria each (e.g. lower middle box) implemented as a class expression that classifies a set of findings. The diagnosis of Level 1 of certainty of anaphylaxis is made by the clinician if the written criteria apply, and by our OWL implementation if the class expression subsumes the set of findings shown in illustration as a Clinical Report.
