Ageing societies - Care quality for older persons at home and in care facilities
This document would specify requirements and recommendations for the provision of health and social care services for older persons provided by healthcare and social care personnel, irrespective of whether the service is provided in the persons own home or in a care home. The services concerned also include those offered to older people who do not reside permanently at a care home, such as temporary accommodations. Care services are provided in a variety of settings. While this document would focus on those delivered in care facilities including preventive, responsive, and palliative care, many of the requirements can be applied to the provision of care services in any setting. Service provision is based on the individual needs and preferences of the older person to assist self-determination, participation, and a safe and secure old age. The document would encompass the compressive needs of care home residents and the workforce, taking into consideration principles of equity, diversity, and inclusion. This document would apply to all providers of care and support to older persons irrespective of size, structure, legal set up, or funding model (i. e. public or private). Care homes, also referred to as residential, long-term care homes, continuing care, personal care, or nursing homes, are residential settings where the majority of residents often live with complex health care needs. They provide a range of professional health services, lodging, food, and personal care (e.g., assistance with everyday activities) for their residents 24 hours/day, 7 days a week. The document is structured to provide clear requirements and accountabilities to enable care home teams, governing bodies, and other stakeholders to work together toward a common vision for resident-centred, high-quality care. This document would be intended to be used in quality assurance, follow-up, evaluation, and development of such services and can be used as a basis for procurement, training, supervision, and certification.

General Information
Overview
ISO/FDIS 25557 - "Ageing societies - Care quality for older persons at home and in care facilities" defines requirements and recommendations for delivering health and social care to older persons, whether in their own homes, temporary accommodation, or 24/7 residential care homes (including long‑term, nursing or assisted living settings). The standard promotes a person‑centred, integrated care approach that supports self‑determination, dignity, equity, diversity and inclusion. It is intended for use in quality assurance, evaluation, procurement, training, supervision and certification of care services. The document does not standardize clinical guidelines or medical devices.
Key topics and technical requirements
The standard is structured to provide clear requirements and accountabilities across the care lifecycle. Major technical topics include:
- Context and governance: understanding stakeholder needs, integrated care coordination, and governing documents for providers.
- Leadership and ethos: leadership commitment, governance, and organisational culture that support resident‑centred care.
- Risk management: prevention, handling of risks to individuals and organisations, emergency and disaster preparedness.
- Workforce and resources: recruitment, training, supervision, staff wellbeing, and workforce governance.
- Facilities and infrastructure: accessibility, maintenance, food safety, environmental stewardship and household services.
- Clinical and support processes: initial assessment, care planning, documentation, medication handling, infection prevention and palliative care.
- Technology and innovation: use of assistive technology and guidance on artificial intelligence in care settings.
- Quality system and improvement: performance assessment, audits, user feedback, complaints handling and continuous improvement.
- Equity and inclusion: requirements addressing diverse needs and protecting human rights of older persons.
Applications and who uses it
ISO/FDIS 25557 is practical for a broad range of stakeholders:
- Care home operators, residential and long‑term care providers
- Home care agencies and community care coordinators
- Healthcare administrators and nursing leadership
- Regulators, inspectors and accreditation bodies
- Procurement officers using standards for contracting services
- Training organisations and workforce developers
- Quality managers and auditors seeking a framework for assessment and improvement
Practical uses include developing policies, designing care pathways, establishing governance and risk frameworks, staff training curricula, procurement specifications, and preparing for certification or external audits.
Related standards
ISO/FDIS 25557 is produced by ISO/TC 314 (Ageing societies) and complements other ISO standards on health management systems, occupational health and safety, and digital health. Organisations should align implementation with applicable national regulations and clinical guidance where relevant.

Introduction
This document supports the United Nations Principles for older persons:
— Older persons should be able to live in environments that are safe and adaptable to personal preferences
and changing capacities.
— Older persons should be able to reside at home for as long as possible.
— Older persons should benefit from family and community care and protection in accordance with each
society’s system of cultural values.
— Older persons should be able to utilize appropriate levels of institutional care providing protection,
rehabilitation, and social and mental stimulation in a humane and secure environment.
— Older persons should be able to enjoy human rights and fundamental freedoms when residing in any
shelter, care, or treatment facility, including full respect for their dignity, beliefs, needs and privacy and
for the right to make decisions about their care and the quality of their lives.
— Older persons should be able to live in dignity and security and be free of exploitation and physical or
mental abuse. Older persons should be treated fairly regardless of age, sex, ethnic background, disability,
or other status, and be valued independently of their economic contribution.
NOTE 1 The first article of the Universal Declaration of Human Rights states that “All human beings are born free
and equal in dignity and rights”. The notion of dignity is defined as the inherent and inalienable worth of all human
beings irrespective of social status such as ethnicity, sex, physical or mental state. Dignity is deeply embedded in
international human rights instruments.
This document is based on the concept integrated care that can be described as methods and strategies for
linking and coordinating the various aspects of care delivered by different care systems, such as the work of
general practitioners, primary and specialty care, preventive and curative services, as well as physical and
mental health services and social care, to meet the multiple needs of an individual older person or category
of persons with similar needs.
An integrated response to care covers health care, social care, care for cognitive diseases, palliative and
end-of-life care, respite care, rehabilitation, services provided at home, in the community, in hospitals or in
care homes, public or private-funded, informal care or care by volunteers.
Care is care, regardless of the environment and should be a seamless provision of health and social services
which are not divided up into silos.
This document adopts a person-centred approach, outlining that care is to be provided with the older
persons’ identity and preferences taking priority. Person-centred care planning is made in close consultation
with the older person, with a goal to improve, restore, and maintain health and wellbeing so the older person
can age with dignity, be respected, and determine how they will live their life while receiving care. For those
persons assessed as “lacking mental capacity” the care planning is made in consultation with appointed
chosen decision maker or representative.
Care providers are responsible for ensuring that the health and wellbeing of the workforce are protected as
this impacts the conditions under which care will be delivered to older persons.
Informal carers provide a high amount of care and support and are able to do so in culturally appropriate
ways that align with the older person’s values. The quality of life of the informal carer is closely linked to the
quality of life of the older person in need of care and support.
Care coordination is needed at a systems level. The integration between social care and health care, both
administratively and at the points of use, is crucial to providing high-quality care. The separation of
social care and health care services can result in fragmented coverage, gaps in the provision of care and
inappropriate use of acute services. This interferes with the rights of older persons to access the support
they need to live to their fullest potential.
viii
A well-supported infrastructure of an aged society includes a comprehensive, holistic framework of health
and care services. See Annex A.
There is also a need for a different approach in the way care and support is organized and a change in the
way older persons and ageing in general are perceived.
Care homes, also referred to as residential care facilities, assisted living facilities, retirement homes or
communities, are settings where the majority of older persons often live with complex care needs. They
provide a range of professional health services, lodging, food, and personal care (e.g. assistance with
everyday activities) for older persons 24 hours a day, every day.
NOTE 2 In some countries medical care is separated from care and is provided by organizations from the health
care sector. When this is the case, the care provider needs to have systems in place to provide medical services or
access to such when needed.
The concepts of healthy ageing and age-friendly environments stresses the importance of enabling the older
person in need of care and support to be involved and empowered to decide how their needs, expectations
and preferences can be met to live as autonomously as possible.

Introduction
This document supports the United Nations Principles for older persons:
— — Older persons should be able to live in environments that are safe and adaptable to personal
preferences and changing capacities.
— — Older persons should be able to reside at home for as long as possible.
— — Older persons should benefit from family and community care and protection in accordance with each
society'ssociety’s system of cultural values.
— — Older persons should be able to utilize appropriate levels of institutional care providing protection,
rehabilitation, and social and mental stimulation in a humane and secure environment.
— — Older persons should be able to enjoy human rights and fundamental freedoms when residing in any
shelter, care, or treatment facility, including full respect for their dignity, beliefs, needs and privacy and
for the right to make decisions about their care and the quality of their lives.
— — Older persons should be able to live in dignity and security and be free of exploitation and physical or
mental abuse. Older persons should be treated fairly regardless of age, gender, racial orsex, ethnic
background, disability, or other status, and be valued independently of their economic contribution.
NOTE 1 The first article of the Universal Declaration of Human Rights states that “All human beings are born free and
equal in dignity and rights”. The notion of dignity is defined as the inherent and inalienable worth of all human beings
irrespective of social status such as race, genderethnicity, sex, physical or mental state. Dignity is deeply embedded in
international human rights instruments.
This document is based on the concept integrated care that can be described as methods and strategies for
linking and coordinating the various aspects of care delivered by different care systems, such as the work of
general practitioners, primary and specialty care, preventive and curative services, as well as physical and
mental health services and social care, to meet the multiple needs of an individual older person or category of
persons with similar needs.
An integrated response to care covers health care, social care, care for cognitive diseases, palliative and end-
of-life care, respite care, rehabilitation, services provided at home, in the community, in hospitals or in care
homes, public or private-funded, informal care or care by volunteers.
Care is care, regardless of the environment and should be a seamless provision of health and social services
which are not divided up into silos.
This document adopts a person-centred approach, outlining that care is to be provided with the older persons’
identity and preferences taking priority. Person-centred care planning is made in close consultation with the
older person, with a goal to improve, restore, and maintain health and wellbeing so the older person can age
with dignity, be respected, and determine how they will live their life while receiving care. For those persons
assessed as 'lacking“lacking mental capacity'capacity” the care planning is made in consultation with
appointed chosen decision maker or representative.
Care providers are responsible for ensuring that the health and wellbeing of the workforce are protected as
this impacts the conditions under which care will be delivered to older persons.
Informal carers provide a high amount of care and support and are able to do so in culturally appropriate ways
that align with the older person’s values. The quality of life of the informal carer is closely linked to the quality
of life of the older person in need of care and support.
vi
ISO/DISFDIS 25557:20252026(en)
Care coordination is needed at a systems level. The integration between social care and health care, both
administratively and at the points of use, is crucial to providing high-quality care. The separation of social care
and health care services can result in fragmented coverage, gaps in the provision of care and inappropriate
use of acute services. This interferes with the rights of older persons to access the support they need to live to
their fullest potential.
A well-supported infrastructure of an aged society includes a comprehensive, holistic framework of health and
care services. See Annex AAnnex A.
There is also a need for a different approach in the way care and support is organized and a change in the way
older persons and ageing in general are perceived.
Care homes, also referred to as residential care facilities, assisted living facilities, retirement homes/ or
communities, are settings where the majority of older persons often live with complex care needs. They
provide a range of professional health services, lodging, food, and personal care (e.g.,. assistance with everyday
activities) for older persons 24 hours/ a day, 7 days a weekevery day.
NOTE 2 In some countries medical care is separated from care and is provided by organizations from the health care
sector. When this is the case, the care provider needs to have systems in place to provide medical services or access to
such when needed.
The concepts of healthy ageing and age-friendly environments stresses the importance of enabling the older
person in need of care and support to be involved and empowered to decide how their needs, expectations
and preferences can be met to live as autonomously as possible.
This document is based on the principle that care and support for older persons needs to evolve in light of the
current social situation. It is important to move away from care that focuses on meeting the basic needs of
older persons to challenge broader objectives such as ensuring wellbeing, meaning in life, and that older
persons feel respected.
As the birth-rate declines and the population ages, caregiving needs to fundamentally evolve to sustainably
meet the growing needs of older persons. The service providers can significantly contribute to promote the
older person’s autonomy.
The providers of care services are expected to develop new ways of thinking through digital technology,
including result-based quality improvement, productivity improvements that support sustainable systems,
and encourage self-determination for users.
To ensure that medical care is provided where people live, including in care homes, networking of medical
and care services in cooperation with health care and social care professionals, medical and care services can
be provided in an integrated manner in the community.
Care and support ought to play a sustained role in maintaining the functional abilities of older persons and
ensuring their dignity, wellbeing, and opportunities for activity and social participation.
The target groups intended to benefit from the results of the proposed document includesinclude:
— Older persons in need of care and support as well persons with caregiving responsibilities, e.g. family and
close friends and volunteers. The main benefits includesinclude safety and security to the older person
receiving care and to their family and friends who support them. The document gives a picture of what the
older person as a consumer can expect of the care service. Key benefits to the older person are
independence, participation, self-fulfillmentfulfilment, dignity, respect, and inclusiveness.
— The provider of care services who provide or deliver care and support will benefit by using the document
as a competence-checklist so that all important aspects of the competence needed in the workforce can be
vii
described and, when relevant, provide an image of the skills development needed within the organization.
The skills required of the workforce include various important qualities such as emotional resilience,
patience, intuition, empathy, and communication skills. These are attributes that, even with the
advancement of digital technology, cannot be provided by robots.
The providers of care services are expected to refer to relevant national guidance about how to deliver safe
and effective care and to implement this in their services. It’sIt is understood that there isn’t always strong
evidence for all aspects of clinical and personal care is not always available. However, where there is evidence,
services should use this to provide best practice care. This provides the best possible basis for decisions about
the type of care provided to meet older persons’ identified needs, as well as the way the provides that care is
provided.
The document is structured to provide clear requirements and accountabilities to enable the workforce,
governing bodies, and other stakeholders to work together toward a common vision for person-centred, high-
quality care services for older persons.
This document is intended to be used in quality assurance and improvement, follow-up, evaluation, and
development of such services and can be used as a basis for procurement, training, supervision, and
confirmation of level of achievement.
Governmental organizations and policy makers will benefit through:
— — Thethe same acceptable equitable level of care being applied regardless of where the older person
lives.;
— — Thethe same set of requirements and recommendations being applied to all within the field regardless
of organization (private or public and non-profit).);
— — Moremore efficient use of tax money.
Different local authorities and municipalities do not have to develop their own templates or tender requests
but can use the document as a common reference in the whole jurisdiction. It facilitates comparisons if all
tenders are arranged in the same way.
An authority which exercises supervision and inspections can use the document as a complement to legislation
that sometimes are more general and needs to be interpreted in relation to the actual elements of the care
service.
This document is intended to be useful to all types and sizes of providers in the private, public, and non- profit
sectors. While not all parts of this document will be of equal use to all types of providers, the principles are
relevant to every provider.
This document can be selectively applied by the provider of care services, recognizing that resources and
supports available will differ from organization to organization depending on the size and sector of the
organization and the jurisdiction.
The text in the clauseseach subclause of this document is divided into three parts, titled “General, ”,
“Requirements” and “Recommendations.”. The text in “General” is written as a vision, a desirable state, that
some care organizations are close to achieve while other organizations have a longer way to go.are still far
from. The “General” part of the clausessubclauses is intended to help the provider of care services to reach the
goal “Care quality for older persons at home and in care facilities” by applying the requirements and the
recommendations in this document in their organization.
When starting to use this document, each provider of care services:

Ageing societies — Care quality for older persons at home and in care
facilities
1 Scope
This document specifies requirements and recommendations for the provision of health and social care
services for older persons provided by healthcare and social care workforce, irrespective of whether the
service is provided in the persons own home or in a care home. The services concerned also include short-
term care e.g. respite care, enablement, and rehabilitation.
Care services are provided in a variety of settings. While this document focuses on services provided in care
facilities and care at home, including preventive, responsive, palliative and end of life care, many of the
requirements and recommendations can be applied to the provision of care services in any setting.
Service provision is based on the individual needs and preferences of the older person to assist self-
determination, participation, safety, and security. The document encompasses the holistic needs of older
persons receiving care at home and at care homes and the workforce, taking into consideration principles of
equity, diversity, and inclusion.
This document applies to all providers of care and support to older persons irrespective of size, structure,
legal set up, or funding model (i.e. public, private or non-profit).
This document does not cover standardization of clinical guidelines, medical devices and building codes
(engineering and structural).

4 Context of the provider of care services
4.1 Understanding the needs and expectations of interested stakeholders
4.1.1 General
Every organization has a purpose, in this case providing care services to older persons. The organization
determines the external and internal needs that are relevant to its purpose and that affect its ability to achieve
the intended results. To make sure the organization understands the issues that can affect, either positively or
negatively, itself and its ability to achieve the intended results of its purpose, information is gained and used
to guide the planning, implementation, operation, evaluation, and improvement of the provision of care
services.
The determined issues represent the main inputs for several other aspects of the operations of the
organization. To understand the needs and expectations of interested stakeholders, the organization
determines:
— — the interested stakeholders that are relevant to the organization;
— — the relevant demands of these interested stakeholders;
— — which of these demands will be addressed through the organizations delivery of its services.
The primary interested stakeholders are the older persons that the organization will provide care for.
This means that the organization needs to have information on demographic data concerning the population
of older persons focusing on the size, composition and change over time. The future challenge of care is to
focus not on all individuals over the age of 65, but mostly on those in the oldest age groups. The oldest-old
people are those with major health and social care needs. The oldest-old population is expected to continue to
increase.
NOTE The concept 'oldest-old people' varies depending on factors such as national regulations, but it is generally
agreed on as those aged 75 or 80 and older.
At the same time, the age composition of the aged population is not the only structural factor affecting the
demand for care. Other factors are socio-economic ones, tax capacity and public health. Changes in the
population structure means that the need for foresight and prioritization in planning and decision-making
processes increases.
The care of older persons in the future refers to what the needs will be and how they can be met in the form
of home care, care homes, etc. Furthermore, it refers to how the workforce supply is met and how the society
works with new technologies. These are issues that together create the conditions for what care for older
persons will look like in the future.
The governing body stays informed about changes in laws, regulations, and contractual obligations that can
affect the delivery of care services and the qualifications of the workforce. When changes are required in the
delivery of care services, the governing body ensures the organization’s strategic plans are aligned to those
changes.
The provider of care services conducts activities to expand the added expected value by each of the
stakeholders in care, while paying attention to their mutual relationships.
For example, these stakeholders and their expected added value can include:
— — governments and local governments (stabilization of civilian populations, economic growth
through welfare, maintenance of market discipline, etc.);
— — communities (seamless and efficient service provision according to life stages);
— — financial contributors (improvement of cost effectiveness of financial resources);
— — older persons and their relatives (provision of high-quality services);
— — care workers (creation of high-quality employment environment).
4.1.2 Recommendations
The provider of care services should ensure that there is a strategic plan that includes, but is not limited to,
the following areas:
a) a) plansPlans concerning demographic information on older persons in the community. Where
are they located geographically? How many are they? What is their age distribution? What is their health
status? What expectations do they have concerning care services?;?
b) b) housingHousing plans that aim to ensure a safe housing situation for the older persons in the
municipality. The housing plans describes, based on the population forecast, the number care homes that
will be needed;.
c) c) workforceWorkforce and proper skills mix supply plans. The plan provides a description of the
current staffing level and based on current staffing and demographic developments, also includes
predictions of what the supply of and skills will look like in both the short and long term;.
d) d) plansPlans for digitalisation and new technology. The plan is a description of the digital
technologies that are already in use and a plan for how digitalisation and new technology can be used in
the future. This requires digital competence among the workforce and efforts to increase the digital
knowledge of the users;.
e) e) plansPlans for health promotion and preventive work programs on the health and wellbeing
of the old
