Overview of the propensity class and a description of the associated data elements |
Data element | Description | Notes |
---|---|---|
Substance | Represents the specific allergen or other agent/substance to which the patient has an adverse reaction propensity. A substance is a physical material which can mean a drug or biologic, food, chemical agent, plants, animals, plastics etc. |
|
Substance type | Represents the type of substance related to the propensity e.g. drug, food, environment, vaccine etc. |
|
Propensity type | Indicates whether the propensity is an allergy, non-allergic hypersensitivity or intolerance. |
|
Propensity certainty | Indicates whether there is evidence that the propensity has been confirmed. For example, an allergy could be further categorized as: Confirmed - via laboratory testing or witnessed observation or other strong evidence, or Suspected (Unconfirmed) - Patient reported but not further verified by clinical history, diagnostic testing or is uncertain. |
|
Propensity criticality | Indicates the potential seriousness of the propensity for a future reaction. This represents a clinical judgment about the worst-case scenario for a future reaction. It would be based on the severity of past reactions, the dose and route of exposure that produced past reactions, and the life threatening or organ system threatening potential of the reaction type. Criticality is an attribute of the propensity, not the reaction(s). | Not the same as severity of the reaction, because a severe reaction can be non-critical and vice versa. |
Propensity status | Indicates the current status of the propensity. For example, an allergy may become ‘Resolved’ after de-sensitization (see 6.2 for the discussion about allergy desensitization). |

---|---|---|
Substance | Represents the specific allergen or other agent/substance to which the patient has an adverse reaction propensity. A substance is a physical material which can mean a drug or biologic, food, chemical agent, plants, animals, plastics etc. |
|
Reaction manifestation | Indicates the specific adverse reaction that occurred. Example: Rash, Hives | A negative entry (e.g., “no adverse reaction observed”) can be used to document an exception to a propensity to a class of substance (e.g., patient has penicillin allergy but can tolerate amoxicillin) |
Reaction severity | How severe the reaction was |
|
Exposure type (route) | How the exposure occurred. Example: oral, airborn, topical, etc. |
|
Source of information | How the observation was made e.g., patient reported, observed by family member, observed by healthcare professional |
