Introduction

The national extensions documented in this implementation guide shall be used in conjunction with the definitions of integration profiles, actors and transactions provided in Volumes 1 through 3 of the IHE IT Infrastructure Technical Framework.

This implementation guide with national extensions of IHE integration profiles was authored in order to fulfil the Swiss regulations of the Ordinance on the Electronic Patient Record (EPRO, SR 816.11). The EPRO and the EPRO-DFI are published in Official Compilation of Federal Legislation (AS) (available in German, French and Italian).

Significant changes, open and closed issues.

Conformance Expectations

The key words MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL in this document are to be interpreted as described in [RFC2119].

This implementation guide uses Must Support in StructureDefinitions with the definition found in Appendix Z. This is equivalent to the IHE use of R2 as defined in Appendix Z.

Scope of precisions

The extensions, restrictions and translations specified apply to the following IHE IT Infrastructure (ITI) Integration profiles:

National integration profiles

The following national integration profiles are included in this implementation guide:

Overview

Introduction

This national extension is motivated by the intention to provide FHIR based profiles for the Swiss EPR by extending the IHE FHIR based mobile profiles. The IHE FHIR based mobile profiles use technologies (REST, OAuth, etc.) which are widely spread in the developer community and may be used for Web Applications, for example in web based primary systems or portals.

This national extension strictly separates the authentication and authorization of the applications use to access the EPR on behalf of the user and the authentication and authorization of the user itself. By using this separation this national extension closely follows the underlying IUA Trial Implementation and OAuth 2.1:

  • Client authentication - an application identifies and authenticates to an authorization server.
  • Client authorization - an application is authorized by the user or system policy to access data and documents on behalf of the user.
  • User authentication - a natural person identifies and authenticates using an Identity Provider with the authenticators registered for the natural person.
  • User authorization - provision of an access token which includes the information required to perform authorization decisions and policy enforcement.

The scope of this extension covers the following use cases:

  1. Client authentication and authorization;
  2. User authentication and authorization;
  3. Read data and documents from the EPR;
  4. Write data and documents to the EPR;
  5. Write logs to the EPR ATNA Audit Record Repository.
  6. Read audit trails for a patient according the EPR requirements.

This extension covers two options:

  1. Generic EPR API option – This option addresses primary systems or portals using the basic EPR flows replacing the XDS.b related and PIX/PDQ V3 profiles with the FHIR based profiles;
  2. SMART on FHIR – This option addresses modular portals or primary systems that want to connect to the Swiss EPR using SMART on FHIR.

Cross Version Analysis

This is an R4 IG. None of the features it uses are changed in R4B, so it can be used as is with R4B systems. Packages for both R4 (ch.fhir.ig.ch-epr-fhir.r4) and R4B (ch.fhir.ig.ch-epr-fhir.r4b) are available.

This includes basic audit log profiles for FHIR RESTful operations to be used when there is not a more specific audit event defined. A focus is enabling Privacy centric AuditEvent logs that hold well formed indication of the Patient when they are the subject of the activity being recorded in the log. Where a more specific audit event can be defined it should be derived off of these basic patterns. (built Wed, Feb 14, 2024 15:23-0600-06:00)
