Health Informatics - HL7 Electronic Health Records-System Functional Model, Release 2 (EHR FM) (ISO 10781:2015)
The HL7 EHR System Functional Model provides a reference list of functions that may be present in
an Electronic Health Record System (EHR-S). The function list is described from a user perspective
with the intent to enable consistent expression of system functionality. This EHR-S Functional Model,
through the creation of Functional Profiles for care settings and realms, enables a standardized
description and common understanding of functions sought or available in a given setting (e.g. intensive
care, cardiology, office practice in one country or primary care in another country).
The HL7 EHR-S Functional Model defines a standardized model of the functions that may be present in
EHR Systems. From the outset, a clear distinction between the EHR as a singular entity and systems
that operate on the EHR, i.e. EHR Systems, is critical. Section 1.1.3 describes the basis and foundation
for the HL7 definition of an EHR System. Notably, the EHR-S Functional Model does not address whether
the EHR-S is a system-of-systems or a single system providing the functions required by the users.
This International Standard makes no distinction regarding implementation; the EHR-S described in
a Functional Profile may be a single system or a system of systems. Within the normative sections of
the Functional Model, the term “system” is used generically to cover the continuum of implementation
options. This includes “core” healthcare functionality, typically provided by healthcare-specific
applications that manage electronic healthcare information. It also includes associated generic
application-level capabilities that are typically provided by middleware or other infrastructure
components. The latter includes interoperability and integration capabilities such as location discovery
and such areas as cross application workflow. Interoperability is considered both from semantic (clear,
consistent and persistent communication of meaning) and technical (format, syntax and physical
connectivity) viewpoints. Further, the functions make no statement about which technology is used,
or about the content of the electronic health record. The specifics of ‘how’ EHR systems are developed
or implemented is not considered to be within the scope of this model now or in the future. This EHR-S
Functional Model does not address or endorse implementations or technology, nor does it include the
data content of the electronic health record.
