Section 1b: EHR - Electronic Health Records
HL7 EHR-System Functional Model, R2
DESCRIPTION
The Electronic Health Record System Function Model Release 2 builds on Release 1.1 of the model, offering a more comprehensive set of functions and criteria. The work is informed by industry advances/directions, regulatory changes, learning from work from functional profiles, and participation by the international community. The work is also balloted through six standards organizations including: ISO, CEN, IHTSDO, CDISC, GS1 and HL7.
ALTERNATIVE NAMES
HL7 EHR-System Functional Model, R2 may also go by the following names or acronyms:
TARGETS
- Immunization Registries
- Quality Reporting Agencies
- Regulatory Agencies
- Standards Development Organizations (SDOs)
- Payors
- Pharmaceutical Vendors
- EHR, PHR Vendors
- Health Care IT Vendors
- Lab Vendors
- HIS Vendors
- Clinical and Public Health Laboratories
- Emergency Servcies Providers
- Local and State Departments of Health
- Healthcare Institutions (hospitals, long term care, home care, mental health)
BENEFITS
- Provides an international standard for global use.
- Enables a consistent framework for the development of profiles which are conformant to the base model
- Supports the goal of interoperability
- Provides a standard that is easily readable and understandable to an ‘everyday person’ which enables a user to articulate their business requirements
DEVELOPMENT BACKGROUND
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 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.
Finally, the EHR-S Functional Model supports research needs by ensuring that the data available to researchers follow the required protocols for privacy, confidentiality, and security. The diversity of research needs precludes the specific listing of functions that are potentially useful for research.
This Functional Model is not:
- a messaging specification
- an implementation specification
- a conformance specification
- an EHR specification
- a conformance or conformance testing metric
- an exercise in creating a definition for an EHR or EHR-S
The EHR-S Functional Model is not sufficient to provide a longitudinal health record; however, it will contribute to its development. The information exchange enabled by the EHR-S supports the population of clinical documents, event summaries, minimum data sets, claims attachments, and in the future will enable a longitudinal health record.
Additionally, it is important to note that the EHR-S Function Model does not include a discussion of clinical processes or the interaction of the healthcare actors. However, ISO13940 System of Concepts to Support Continuity of Care is an international standard that does outline key principles and processes in the provision of healthcare. We would highly recommend that users of the EHR-S FM refer to this standard for clinical processes that EHR systems support.
