Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
Personal health decision support (PHDS) enables personalized decision support for self-care decisions
by processing health data provided by or on behalf of an individual. It is designed to assist individuals in
making informed decisions about their health by delivering context-specific recommendations, alerts, or
guidance derived from personal health data. PHDS is implemented as a standalone service or as part of a
health platform (for example, an electronic health record system or a health application) and can support a
wide range of use cases.
Self-care is an activity in which individuals manage their own health, including health promotion, disease
[1]
prevention and control, self-medication, and rehabilitation. The World Health Organization (WHO)
defines self-care as “the ability of individuals, families, and communities to promote health, prevent disease,
[2]
maintain health, and cope with illness and disability with or without the support of a health worker”.
WHO also says: “on average, individuals spend less than one hour a year with a health worker versus over
[2]
8 700 hours a year in self-care”. Self-care interventions are tools or strategies that can promote health,
prevent disease, manage chronic conditions, and cope with illness or disability with or without the support
[1][2][3]
of healthcare professionals. Persons choose self-care interventions for various reasons, such as
[2][4]
convenience, confidentiality, and cost. The self-care interventions are evidence-based and provided to
[5]
individuals in ways that better support self-care.
This document defines interoperability for seamless interaction among stakeholders, including PHDS
services, data providers, and PHDS clients, to support the safe and effective use of PHDS. It highlights
the importance of standardized data exchange, validation, and communication while also addressing the
essential privacy and security considerations that ensure user trust.
