ISO 27269:2025

Overview

ISO 27269:2025 - Health informatics - International patient summary (IPS) - defines the core data set for a concise, portable International Patient Summary (IPS). The standard provides an abstract definition of an IPS from which derived, implementable models can be produced. Its scope is to support continuity of care and care coordination by specifying what core information an IPS should contain, while explicitly excluding workflow processes, the human summarization act, and low‑level technical implementation details (such as representation by particular coding schemes or transport layers).

Key topics and technical requirements

• Core IPS Data Blocks: The standard organizes the IPS into data blocks (sections/features) that describe essential clinical and administrative information needed for cross‑setting care continuity.
• Descriptors for the IPS data set: Detailed descriptors define purpose, definitions, business rules, inclusion criteria, currency and format expectations for each data block.
• Patterns and data types: Common data patterns (e.g., coded elements, identifiers, date/time, person name, address, text, lists, ranges) are specified to ensure consistency in how elements are described at an abstract level.
• Model extensibility: Guidance on how the IPS model can be extended while keeping the core data set interoperable and consistent.
• IPS Document structure: A defined document-level description (purpose, definition, rules for missing data, examples) to support consistent IPS exchanges.
• Patient and provider features: Explicit, structured descriptors for critical features such as Patient Attributes and Healthcare Provider information (purpose, inclusion rules, formats, currency).

Note: ISO 27269:2025 is an abstract model - it does not prescribe encoding, terminologies, or technical transport/implementation profiles.

Practical applications

• Supports cross‑border and cross‑setting healthcare information sharing by defining the minimum data needed for safe, informed care decisions.
• Enables health systems and organizations to derive implementable IPS models tailored to local legislation and technical stacks.
• Facilitates design of data mappings, interoperability profiles, and specifications used by EHR vendors, health information exchanges, and national health authorities.
• Useful in emergency care, referrals, care transitions, and any scenario requiring a concise patient summary to support continuity of care.

Who should use this standard

• Health informatics architects and EHR system designers
• National and regional health authorities defining IPS implementations
• Standards bodies and implementers developing interoperability profiles
• Clinical informaticians and policy makers planning cross‑setting care continuity

Related standards

ISO 27269 complements other international and national health informatics standards and implementation frameworks used to realize interoperability (clinical terminologies, messaging/RESTful APIs, and national IPS implementation guides). Implementers should pair ISO 27269’s abstract model with suitable technical standards and terminology bindings for real‑world deployments.
