eHDSI in ART-DECOR

About eHDSI

The eHealth Digital Service Infrastructure (eHDSI or eHealth DSI) is the initial deployment and operation of services for cross-border health data exchange under the Connecting Europe Facility (CEF). eHDSI sets up and starts deploying the core and generic services, as defined in the CEF, for Patient Summary and ePrescription. The generic services are the necessary implementation of data exchange at country level, the core services at EU level. These together enable the provision of Cross Border eHealth Information Services (CBeHIS).

History

This project was initially started as the epSOS Large Scale Pilot, where a first version of the CDA implementation guides were created. The transcription to ART-DECOR of the normative master specification for epSOS was originally done by the Dutch National IT Institute for Health Care (Nictiz) end of 2013 / beginning of 2014 as part of an official agreementbetween the epSOS project and Nictiz.The specification as of now is the result of a review of the original epSOS specification. This was done within the EXPAND project WP5, before moving the specification to CEG. The activity was supported by HL7 International /HL7 International Foundation / HL7 Europe. The eHDSI project uses the CDA Implementation Guides of EXPAND asa base for further development.

The CDA IGs of the epSOS project are still available: https://art-decor.org/art-decor/decor-project--epsos-. No active development is done on this project, that served as a base for the eHDSI CDA IGs.

Use cases

Within the eHDSI project, three main use cases are defined:

• Patient Summary: access to important medical data for patient treatment.
• ePrescription/eDispensation: cross-border use of electronic prescriptions.
• OrCD: cross-border exchange of following types of embedded original clinical documents:

1. Laboratory Results
2. Hospital Discharge Reports
3. Medical Images
4. Medical Imaging Reports

Release notes of the CDA Implementation guides can be found at the following location: https://webgate.ec.europa.eu/fpfis/wikis/x/9AVoNg

The value sets that are used inside the project are combined in a master value set catalogue (MVC): https://webgate.ec.europa.eu/fpfis/wikis/x/8gNoNg

The Central Terminology Server (CTS) is a set of components used for the representation, access, and maintenance of the terminology content of the electronic documents exchanged within eHealth Digital Service Infrastructure (eHDSI). The CTS aims at supporting the Member States in coordinating their terminology efforts. More information on the CTS can be found in Confluence: https://webgate.ec.europa.eu/fpfis/wikis/x/PgJoNg

Notes for reading this specification:

• This specification uses flavors for HL7 V3 datatypes where applicable:
  • AD.EPSOS - checks if there is at least one element if not null
  • CD.EPSOS - allows nested translations, and requires @displayName if @code is used
  • CE.EPSOS / CO.EPSOS / CV.EPSOS - see CD.EPSOS
  • II.EPSOS - OID SHALL be <= 64 characters
  • IVL_TS.EPSOS.TZ / TS.EPSOS.TZ - SHALL be precise to the day, SHALL include a time zone if more precise than to the day, and SHOULD be precise to the second.
  • IVL_TS.EPSOS.TZ.OPT / TS.EPSOS.TZ.OPT - SHALL be precise at least to the year, SHOULD be precise to the day, and MAY omit time zone.
  • TEL.EPSOS - Phone/fax SHALL have pattern '^\+?[0-9()\.-]+$' and SHALL have at least 1 dialing digit
