aiExpert In Practice – #4 – Healthcare Data Model
Shows a summary of the feedback on some parts of a large, public domain healthcare model from Canada
Source model
This data was taken from the CIHI model, available here.
We used exactly the same settings as example #1, and show just a few highlights from a few of the many diagrams in this model.
As with the other example, we make no comment about whether the feedback form aiExpert is good or bad, relevant or stupid. But it’s mostly interesting. Nothing here should be taken as a criticism of this model, which is clearly comprehensive and well thought-out.
Allergy and Intolerance
This is a reat example of where the AI can provide domain-specific feedback. We don’t know if that feedback is exactly correct in this instance, but it might be.
Issue: The model requires each Patient Allergy or Intolerance to be ‘documented in one Encounter Patient’. In practice, allergies/intolerances are often recorded at the patient-level outside of a specific encounter (e.g., allergy list maintained in a longitudinal record). Forcing a required relation to an Encounter may prevent representing patient-level allergy records.
Suggested fix: Patient Allergy or Intolerance documented in zero or one Encounter Patient (optional). Allow allergies to exist as patient-level records independent of an encounter.
Patients and Party Role
This is a model idea which many data modelers will have grappled with: the idea of a person/organization, and the roles they they can take in the world. We have no idea if is this feedback is valid for this domain, but it sure looks interesting.
Issue: Patient is modeled as a subclass of Party Role but the ‘Patient’ class description reads as a person (entity). This mixes the concept of a party (the person/organization) with the role (the fact they are a patient). The model lacks an explicit Party/Person/NonPersonEntity class, which can lead to confusion about which relationships are to the person vs. to the role.
Suggested fix: Introduce a clear Party (or Person) entity class. Make ‘Patient’ a Party Role that references a Party/Person. Update relationships to distinguish between the person (Party) and the role (Patient).
