I'm not sure I know of an EMR that doesn't have a section dedicated to allergies.
Certainly doctors would be used to having an allergy section.
At least being able to easily add Allergy as the first word in the Reason column would be a good idea.
Another problem would be the co-mingling of allergies and discontinued drugs makes reporting allergies to other physicians difficult. Does a doctor receiving my referral note really want to know the 4 NSAIDs, 5 SSRIs, 3 Sleeping pills and 2 statins the patient eventually stopped ?
I think most doctor expect a section dedicated to allergies. Drugs stopped b/c of intolerances and the million other reasons could go in another category.
