## IPS to EPS Alert Comparison

ISO 27269 ↔ EU Patient Summary – Alerts Mapping

### 📘 ISO 27269 → EU Patient Summary — Alerts

ISO 27269 (IPS) | Conformance | Relationship | EU Patient Summary
--- | --- | --- | ---
Element | Conf. | Relation | Element | Notes
Alert | M | Equivalent | Alert | Core entry element; represents a patient alert or flag.
Alert type | RK | Not represented | code | the type is represented by a category element that seems to be missing.
Alert identifier | RK | Equivalent | header.identifier | Same function — business or system identifier of the alert record.
Alert description | R | Equivalent | text | Free-text description of the alert; EHDS adds examples and narrative guidance.
Alert level | RK | Equivalent | priority | Same semantics — indicates severity or importance; EHDS uses coded values instead of numeric levels.
Disease-related diagnosis | O | source-broader-than-target | code | Represented as part of the coded alert; can point to a diagnosis concept (e.g. SNOMED CT).
Disease name | O | Equivalent | code.text | May appear within the narrative; not a structured field in EHDS.
Onset date | RK | Equivalent | period.start | Equivalent meaning — start of the alert’s active period.
Assertion degree | RK | Not represented | — | Not represented in EHDSAlert, doesn't seem to be realized by the FHIR IPS
Confirmation method | RK | Not represented | — | Not represented in EHDSAlert, doesn't seem to be realized by the FHIR IPS
Specialist contact | O | Not represented | — |
Reference to specialist advice / guideline | O | Not represented | — |

### 📗 EU Patient Summary (EHDS Model) → ISO 27269 Alerts

EU Patient Summary | Relationship | ISO 27269 (IPS)
--- | --- | ---
Element | Relation | Element | Notes
EHDSAlert | Equivalent | Alert | Core concept aligned — both define a clinical alert or flag associated with a patient.
header | Partial | — | Administrative header (subject, authoring, status, etc.) not part of ISO 27269 clinical section content.
header.subject | Not represented | — | Patient identification handled elsewhere in ISO 27269 Document Header.
header.identifier | Equivalent | Alert identifier | Same meaning — unique identifier for the alert entry.
header.authorship / author[x] / datetime | Not represented | — | Authorship metadata only related to the document; ISO 27269 section does not define this.
header.lastUpdate | Not represented | — | Technical metadata; ISO does not define this.
header.status / statusReason | Not represented |  |
header.language | Not represented | — | Resource-level metadata; not part of ISO section.
text | Equivalent | Alert description | Free-text narrative; may include disease or alert explanation.
priority | Equivalent | Alert level | Both indicate the alert’s severity or urgency; EHDS uses coded priority values.
status | Not represented |  | Corresponds to the state of the alert (active, inactive, etc.).
code | source-broader-than-target | Disease-related diagnosis | Represents the coded alert type, diagnosis, or category (e.g., SNOMED CT). The alert code is not necessarly limited to diagnosis.
period.start | Equivalent | Onset date | Same clinical meaning — when the alert became relevant.
period.end | Not represented | — | ISO does not define an end date; alerts are typically active/inactive only.
