This document specifies a means for communicating part or all of the electronic health record (EHR) 
of one or more identified subjects of care between EHR systems, or between EHR systems and a 
centralised EHR data repository.
It can also be used for EHR communication between an EHR system or repository and clinical 
applications or middleware components (such as decision support components), or personal health 
applications and devices, that need to access or provide EHR data, or as the representation of EHR data 
within a distributed (federated) record system.
This document will predominantly be used to support the direct care given to identifiable individuals 
or self-care by individuals themselves, or to support population monitoring systems such as disease 
registries and public health surveillance. Uses of health records for other purposes such as teaching, 
clinical audit, administration and reporting, service management, research and epidemiology, which 
often require anonymization or aggregation of individual records, are not the focus of this document 
but such secondary uses might also find the document useful.
This Part 1 of the multipart series is an Information Viewpoint specification as defined by the Open 
Distributed Processing – Reference model: Overview (ISO/IEC 10746-1). This document is not intended 
to specify the internal architecture or database design of EHR systems.nd edition 2019-06 Health informatics — Electronic health record communication — Part 1: Reference model Informatique de santé — Communication du dossier de santé informatisé — Partie 1: Modèle de référence Reference number ISO 13606-1:2019(E) ？ ISO 2019 ISO 13606-1:2019(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2019 All rights reserved.
