ISO 27269:2025 — International Patient Summary (IPS) for Health Informatics
Standardized Core Dataset for Cross-Border Care Coordination and Continuity of Care
1. Overview and Clinical Context
ISO 27269:2025 defines the core dataset for the International Patient Summary (IPS), a standardized, minimal dataset that enables continuity of care across healthcare settings and national boundaries. The IPS contains essential health information including allergies, medications, problems/diagnoses, immunizations, and procedures — structured for machine readability and clinical usefulness.
For health IT architects: The IPS is designed as a “minimum non-negligible” dataset — the smallest amount of clinically relevant information that is still useful for unscheduled care. This is a fundamentally different design philosophy from comprehensive EHR data exchange.
2. Core Dataset Structure
The standard defines the IPS as an abstract model with mandatory and optional sections. The mandatory sections include: patient demographics, allergies and intolerances, current medications, active problems, immunizations, and medical history. Optional sections cover social history, pregnancy status, medical devices, and functional status.
| Section | Mandatory/Optional | Key Data Elements | Clinical Rationale |
|---|---|---|---|
| Patient demographics | Mandatory | Name, date of birth, sex, identifier | Patient identification and matching |
| Allergies and intolerances | Mandatory | Substance, reaction, severity | Prevent adverse drug events |
| Current medications | Mandatory | Medication name, dose, route | Medication reconciliation |
| Active problems | Mandatory | Diagnosis, onset, status | Care continuity |
| Immunizations | Optional | Vaccine, date, dose number | Preventive care |
| Medical devices | Optional | Device type, identifier | Implant management |
3. Technical Implementation and Interoperability
The IPS uses a modular architecture compatible with HL7 FHIR (Fast Healthcare Interoperability Resources) and CEN EN 17269. The standard requires coded data using international terminologies including ICD (diagnoses), ATC (medications), and SNOMED CT (clinical concepts). Machine-readable formats enable direct integration into EHR systems, while human-readable representations support paper-based workflows.
Engineering insight: The IPS represents a paradigm shift from “send everything” health information exchange to “send the essentials” — dramatically reducing implementation complexity while maintaining clinical safety for unscheduled care scenarios like emergency departments and travel medicine.
4. Governance and Data Quality
The standard does not prescribe workflow processes for data entry, summarization, or clinical decision-making. Instead, it defines the output format. National extensions and implementation guides build upon this core standard to address specific jurisdictional requirements. The 2025 edition incorporates lessons learned from COVID-19 pandemic deployments across Europe and Asia.
Important limitation: ISO 27269 is an abstract definition standard. It does not provide implementation guides for the technical layers beneath the application layer — these are covered by companion implementation guides and national profiles.
Privacy consideration: While the IPS improves care coordination, it also concentrates sensitive health data. Implementers must ensure compliance with applicable privacy regulations (e.g., GDPR in Europe, HIPAA in the US).
5. Frequently Asked Questions
Q: How does the IPS differ from a traditional medical summary?
A: The IPS is standardized, machine-readable, and designed specifically for cross-border and cross-setting care coordination rather than within-organization continuity.

Q: Is FHIR the only supported exchange format?
A: No, the IPS is format-agnostic at the abstract level. FHIR, CDA, and proprietary formats can all represent IPS content when properly mapped to the defined data model.

Q: What is the relationship between ISO 27269 and CEN EN 17269?
A: EN 17269 is the European regional implementation of the IPS specifications, harmonized with ISO 27269 for global applicability.

Q: Who maintains the IPS dataset definitions?
A: The IPS dataset is maintained jointly by ISO/TC 215 (Health informatics) and CEN/TC 251, with input from clinical specialty organizations and national health authorities.
