International Patient Summary Implementation Guide

This is the latest build of the Trillium II Implementation Guide, based on FHIR Version 3.0.1. See the Directory of published versions. This specification is the version currently used by the Trillium II community of practice. It is subject to change, which may be significant, as part of the Trillium II maintenance process. A stable version will be epublished at the end of the project.

Feedback is welcome and may be submitted through the Trillium II GitHub issue tracker.


Specify a Trillium II project International Patient Summary (IPS) HL7 FHIR Implementation Guide, inspired by the CEN/HL7 IPS standards, formalizing the results of the Work Package 2 and 3 of the Trillium II project.


The International Patient Summary

An International Patient Summary (IPS) document is an electronic health record extract containing essential healthcare information about a subject of care. It is specifically aimed at supporting the use case scenario for ‘unplanned, cross border care’, but it is not limited to it. It is intended to be international, i.e., to provide generic solutions for global application beyond a particular region or country.

The IPS dataset is minimal and non-exhaustive; specialty-agnostic and condition-independent; but still clinically relevant.

The IPS is composed by a set of robust, well-defined and reusable core set of data items, i.e., HL7 FHIR IPS profiles, in the case of this guide. Its tight focus on unplanned care is not a limitation, but, on the contrary, enables the IPS profiles to be used as common minimal ‘core’ set beyond its initial scope.

The Trillium II project

Trillium Bridge II - Reinforcing the Bridges and Scaling up EU/US Cooperation on Patient Summary is a project funded from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 727745, aiming to:

  • Improve international interoperability of Health systems in Europe, the United States, and globally
  • Accelerate adoption of interoperability standards in eHealth with validated open source interoperability assets and tools sharing experiences and lessons learned among standards organizations and patient initiatives
  • Identify key use cases for secure, seamless sharing of patient summaries at personal and population levels.

In this context Trillium II has investigated the adoption of the International Patient Summary (IPS) beyond the cross border unscheduled care scenario, extending its concept from a pure docuemntal approach to a reusable system of data blocks.
