International Patient Summary Implementation Guide
2.0.0 -

International Patient Summary Implementation Guide, published by HL7 International / Patient Care. This guide is not an authorized publication; it is the continuous build for version 2.0.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-ips/ and changes regularly. See the Directory of published versions

## Known Issues and Future Development

Page standards status: Informative

### Known Issues

1. Lack in representation of the summarization activities, including who did it, what was done (medication reconciliation, allergy reconciliation, medication allergy reconciliation, immunization/vaccination reconciliation, problem list/diagnosis reconciliation), what was the result, when and where was it done. This covers also the "Nature of the IPS" element included in ISO 27269.
2. Profile specificity to be improved. Not all the expected rules can be automatically validated, due to a lack of representation in the specified profiles.
3. All of the slicing rules defined for the section entries have been specified in this version as open. This choice has been made to give more flexibility to the IPS, at the expense of the capability of fully and automatically validating the instances. In this sense the profile may technically allow the inclusion of inappropriate resources. Specifiers are encouraged to add further constraints or additional slices to mitigate this risk. Future versions may reconsider the current choice.
4. More constrained vocabularies. The choices made in this version reflect the need of balancing the expectations of reducing optionality, to improve interoperability; and of avoiding over-constraints, to facilitate the local adoption. Moreover, it has been recognized the current lack, in some cases, of globally recognized and freely usable vocabularies (e.g. for the identification of medications); and the need, for specific concept domains, to extend the value sets based on new SNOMED CT and SNOMED IPS Terminology content. For these reasons, the binding is required only in a few cases; preferred or extensible bindings have been used instead.

### Future Development

1. Explore the adoption of the Provenance resource with the IPS (bundle level, composition level or entry level) to document the IPS curation as documented in the first known issue above (see also the "International Patient Summary: Use Cases" confluence page)
2. Include additional guidance or references on approaches for selecting appropriate summary content, documenting algorithmic vs. human curation of data, and generating narrative representations. A draft page on the various Methods for IPS generation has been drafted on HL7 Confluence and may be a consideration for future version of this IPS FHIR Implementation Guide.
3. Gather feedback on the IPS $summary operation introduced in STU1.1 of the this guide.

8. Check value Set OID alignment between FHIR and CDA IPS IGs FHIR-46169
9. Add NutritionIntake Observation profile in Social History FHIR-46923
10. Add Patient Travel History FHIR-47930
11. Add NUVA as additional vaccine binding FHIR-49146
12. Add 'disability' to ValueSet: Problem Type - IPS FHIR-49218
13. Add CarePlan (IPS) Profile, based on ISO 27269 FHIR-49905
14. Guidance on laterality in IPS FHIR-50042
15. Add a CareTeam section, and describe how to use it for patient advocate / legal power of attorney FHIR-50098
