3. Notes and Issues • See meeting minutes from Elaine • Hypersensitivity: associated to Allergy • Sensitivity can be positive or negative. Keep ‘Adverse’ • Agent: use Substance • Symptoms: use ‘Manifestations’ • Criticality: • The result of the clinical assessment and judgment, tied to condition • Should it be tied to AR? • Can have an AR without a predisposition/ condition • Is Adverse Reaction an Event? • Is Adverse Effects the same as Adverse Reaction? • Is Adverse Event the same as Adverse Effects, or is the Event the cause of the Effects
