Introduction
ISO/TC 215 has identified that there is an urgent need to provide International Standards for health
information architectures that includes requirements tailored also to low- and middle-income countries
with relatively immature resources available. A Public Health Task Force of international experts,
established by TC 215, has developed a report outlining the challenges these countries face and some of
the relevant standardization strategies.
This part of ISO/TR 14639 provides a guide to best practice business requirements and principles for
planning the use of information and communications technology (ICT) to support the development,
coordination, and delivery of healthcare services by countries and subordinate health authorities within
a country.
One of the activities motivating this work originates from a meeting in March 2010, in Bellagio, Italy to
[10]
explore how the “digital divide” between high-income and low-income countries could be addressed.
The following observations were noted.
a) There is a surge of interest in the development of eHealth infostructure to support effective Health
Information Systems (HIS) in low-income countries, including responding to disease outbreaks,
monitoring the health status of the population, and improving both public and individual health.
b) Health informatics International Standards help countries to make the proper decisions regarding
their eHealth architecture such that they can strengthen their health systems. HIS architectures
that are non-proprietary and based on International Standards are likely to be more robust and
future-proof.
c) The use of health informatics International Standards in low-income countries is hampered due
to lack of knowledge and awareness about appropriate standards, affordable access to standards
and implementation guides, and little participation in Standards Development Organization (SDO)
activities due to little or no funding to support such engagement.
d) Existing international health informatics International Standards insufficiently address the
needs of low-income countries (LICs) for developing their monitoring, public health, and patient
care systems. An example of this is mobile computing and the use of SMS for transmitting patient
information, reminders, and alerts. Thus, the participation of LICs in the International Standards
development process is essential.
e) Participation in ISO activities requires a national standards organization or government department
as an official member of ISO.
f) Development of International Standards has a cost. A significant amount of money and time needs
to be invested in preparation of documents, commenting on proposals, and participation in SDO
meetings and for adopting, adapting, and localization of standards. These costs represent a genuine
barrier to the participation of low-income countries.
g) Access to International Standards also comes with a cost that is often prohibitive for people and
organizations in low-income countries.
h) There is recognition that the business model of some SDOs is based on the sale of International
Standards to support the standards development process and operating expenses.
i) HIS strengthening can be promoted by using commonly shared International Standards to carry out
Monitoring and Evaluation (M & E) activities for government bodies, international organizations,
donors, and other interested parties.
j) There are duplications and overlaps in health informatics International Standards across multiple
SDOs. Low-income countries require a single set of usable International Standards based on the
work of ISO/TC 215, HL7, and CEN/TC 251 Joint Initiative Council (JIC) to harmonize International
Standards and facilitate the global, international adoption, and adaption of organizational and
regional standards based on the ISO standards process.
k) Promotion of International Standards worldwide is consistent with the ISO mission yet barriers
exist to the achievement of this objective.
While not all of these observations are addressed within the scope of this Technical Report, the report
is an attempt to respond to some of these observations, providing a robust framework for low-income
countries for their eHealth architecture planning and health system development. The other items are
intended to be addressed in due course.
This part of ISO/TR 14639 examines various activities and associated criteria for the effective use of
information and communication technology (ICT) in support of health service delivery, planning, and
coordination. It aims to provide relevant guidance on uses of information, based on model criteria by
which development of eHealth capability can be planned and progress toward its mature use can be
assessed.
In preparing this part of ISO/TR 14639, the original aim was to provide guidance for developing
and emerging countries and for the many international groups that conduct health programs in the
developing and emerging world. As the work proceeded, it became clear that the work is more widely
applicable to all health services and that there are potential lessons for all as they examine the way in
which information is produced, managed, and used in various aspects of their work. The identification
of relevant health informatics standards and the role of international standardization in support of
eHealth were also important drivers.
This part of ISO/TR 14639 builds on lessons from many countries, including those whose activities are
summarized in ISO/TR 14639-1 and was, in large part, inspired by experience with the Health Metrics
Network (WHO/HMN Framework) activities sponsored by the World Health Organization (WHO).
The particular focus of this part of ISO/TR 14639 is the potential for ICT to assist in the collection,
communication, storage, processing, and use of information to support the delivery, planning, and
coordination of health services; however, it also recognizes the importance of initial measures that
involve paper-based collection and the need for a migration path from manual to semi-automated to
fully automated information management systems.
The enterprise-wide business reference architecture described in this part of ISO/TR 14639 represents a
starting point for the enterprise viewpoint or business layer of a comprehensive enterprise architecture,
which would include other layers or viewpoints, such as the information/data, computational/function,
engineering, and technology perspectives. This model would serve, for example, to assist in identifying
initiatives and exploring the attributes of the components that would form a national eHealth strategy.
A comprehensive enterprise architecture is typically set up and maintained using a structured process
that involves the following:
a) an organized approach to ensuring that investments in ICT technology and information systems
meet overall priorities for effective operation and delivery of healthcare services and the information
needed for their planning, development, and continuous improvement;
b) identifying and describing the main attributes of the eHealth information services, components,
activities, and policies needed to support the operational requirements for health services within a
jurisdiction (or organization);
c) development of structured requirements for more detailed planning and investment in health
information systems and for the development and dissemination of health information policies.
Where relevant, this part of ISO/TR 14639 takes advantage of and makes reference to the principles,
policies, and specifications set out in relevant International Standards and existing architectural
frameworks commonly used in the health sector including: ISO 12967, Health Informatics Service
[1][2][3]
Architecture (HISA), the vision and principles of the World Economic Forum (WEF) Global Health
[4] [5]
Data Charter as seen in Annex A, and the Health Enterprise Architecture Framework (HEAF).
A layered approach to structuring of information architectures and models is proposed in this part
of ISO/TR 14639, based on similar approaches such as the General Component Model introduced in
vi © ISO 2014 – All rights reserved

[6] [7] [8] [9]
Annex B, the WHO Health Metrics Network Framework, TOGAF, and the Zachman framework.
In particular, HISA and the HEAF have been developed specifically to assist in the process of defining
eHealth architectures for use in health services. See Annex C for more information on HISA. A short list
of selected health informatics International Standards upon which the architectural components are
based is found in Annex D. See 6.1.4 regarding governance and national ownership of eHealth standards
adoption and implementation.
[93]
In May 2012, WHO and ITU published a National eHealth Strategy Toolkit that embodies most of the
concepts relevant to an Enterprise Architecture, tailored to the creation of a National eHealth Strategy.
This resulted in a process that is exhaustive yet streamlined and easier to understand and apply. The
Toolkit presents a thorough step-by-step set of methods, checklists, and examples to be used by country
or region-level managers when developing an eHealth Strategic Vision, an eHealth Action Plan, and a
Monitoring and Evaluation Plan. The WHO-ITU National eHealth Strategy Toolkit and ISO/TR 14639-1
and this part of ISO/TR 14639 form a complementary set of tools for the design and deployment of an
eHealth architecture.
The architectural components and their characteristics as described in this part of ISO/TR 14639
are designed to be reviewed and, where appropriate, adopted by countries and subordinate health
authorities at a level relevant to their specific needs. In particular:
a) The components and characteristics may be used as model requirements in developing enterprise
architectures or as a means of assessing and improving eHealth maturity.
b) Each component is configurable to meet local needs by describing characteristics indicative of a
range of capability from the most basic through to the highly advanced.
c) The characteristics of various capacity levels for each component form the basis of the underlying
maturity model.
d) Typical starting points for the development of capability are provided for each of the components at
the lowest maturity level, together with the basic principles the architecture should adhere to.
e) There is an emphasis on developing appropriately layered, well-structured eHealth architectures
with well-defined and preferably standardized interfaces between the various components and
layers.
f) There is a particular focus on potential eHealth requirements relevant to low- and middle-income
(LMIC) countries.

roadmap —
Part 2:
Architectural components and maturity model
1 Scope
This part of ISO/TR 14639 provides a guide to best practice business requirements and principles for
countries and their subordinate health authorities planning and implementing the use of information
and communications technology (ICT) to support the delivery and development of healthcare. A business
reference architecture is described in terms of components and capabilities that health authorities may
use as a framework for building their own eHealth architectures and also for measuring the maturity of
their health systems’ use of ICT to support the delivery and development of healthcare.
It is worth noting that while this part of ISO/TR 14639 was developed with a particular view to support
low- and middle-income countries, it can also be a useful guide for any country. Even if maturity is high
in some aspects, highly developed countries may still need advice on architectural components for some
aspects of a total eHealth system.
The development of eHealth architectures based on the guidelines set out in this part of ISO/TR 14639
will facilitate and optimize investments in Health Information Systems to achieve the following goals:
a) information being used cost-effectively for improvement of health services;
b) health information being harmonized, consistent, accessible, and able to be used effectively;
c) patients, health professionals, and policy-makers having the right data available to make decisions
about health services, treatment, and delivery of care;
d) appropriate information being available to support evidence-based practice and health services
planning, health services quality, and safety and to improve public health;
e) improving accessibility to healthcare services;
f) supporting harmonization of Health Information Systems and health information standards.
It is envisaged that this part of ISO/TR 14639 will be a valuable source of information for
g) personnel responsible for health services policy, planning, and provision,
h) those developing health information resources and eHealth policy at national and subordinate
levels in a country,
i) non-governmental organizations (NGOs) and others seeking to support or implement systems for
information gathering, statistics, and care delivery in developing and emerging economies,
j) developers and implementers of Health Information Systems and services,
k) academic and research institutions and students in health informatics, and
l) other stakeholders in the health sector.
This part of ISO/TR 14639 also proposes a maturity model and methodology that organizations may
consider in developing and evolving their eHealth capacities in specified areas of operational capability
from low to medium to high levels. The proposed business reference architecture identifies components
and capabilities needed to support various health service activities along with the governance,
infostructure, and ICT infrastructure that is necessary for the effective and efficient use of information
in the delivery and development of health services.
