Abstract
An ageing population is posing a great challenge
to Hong Kong. Maintaining health and functional
independence among older adults is of utmost
importance, and requires the collaborative efforts of
multiple health care disciplines from both the private
and public sectors. The Reference Framework for
Preventive Care for Older Adults, developed by the
Task Force on Conceptual Model and Preventive
Protocols under the auspices of the Working Group
on Primary Care, aims to enhance primary care for
this population group. The reference framework
emphasises a comprehensive, integrated, and
collaborative approach that involves providers of
primary care from multiple disciplines. In addition to
internet-based information, helpful tools in the form
of summary charts and Cue Cards are also produced
to facilitate incorporation of recommendations by
primary care providers into their daily practice. It
is anticipated that wide adoption of the reference
framework will contribute to improving older adults’
health in our community.
Introduction
Advances in medicine and increased life expectancy
mean that Hong Kong is expecting an ageing
population, and a significant increase in the number
and proportion of older adults. According to the
Census and Statistics Department of Hong Kong
SAR, it is estimated that by 2041, the number of
Hong Kong residents aged 65 years and above
will increase from 0.9 million in 2011 (13% of
the population) to around 2.6 million (30% of the
projected population).1
This ageing population poses not only a threat
but also a challenge to the current health care system.
It is anticipated that the prevalence of common
chronic diseases will be further increased with a
consequent escalating demand on various health
services for older adults. Strategies to promote
health, prevent chronic diseases, and preserve
functional ability of older adults are therefore vital.
In order to provide a general reference for
provision of continuous, comprehensive, and
evidence-based care for older adults in the primary
care setting, the Reference Framework for Preventive
Care for Older Adults in Primary Care Settings2 was
developed by the Task Force on Conceptual Model
and Preventive Protocols under the auspices of the
Working Group on Primary Care. It was developed
according to the latest research evidence, with
contributions from the Clinical Advisory Group
that comprises experts from academia, professional
organisations, private and public primary care
sectors, and patient groups.
The reference framework consists of a core
document supplemented by a series of modules that
address various aspects of disease management and
preventive care for older adults.2 To date, the core
document, and the modules on health assessment
and falls have been developed.
This article summarises the main contents and
highlights a practical use of this reference framework
to enhance the delivery of preventive care for older
adults in primary care setting in Hong Kong. Details
of the evidence that supports the recommendations
are available in the core document of the reference
framework.2
Role of primary care in the preventive care of older adults
As the first point of contact, primary care providers
are in a prime position to promote health, prevent
and monitor disease, and reduce functional
disabilities.3 Primary care physicians provide health
education, risk assessment, and follow-up care
for medical conditions. They also advise and refer
patients for appropriate health care services as
necessary, and provide support and advice to family
members and carers. It is firmly established that
patient education and counselling in the primary
care setting contributes to a better understanding of
health and can thus influence an individual to adopt
health protective behaviour.4
Only 0.5% of clinical encounters among older
people at a local primary care level are initiated
for a physical checkup.5 It has been suggested that
apart from designated appointments in primary
care settings, health assessment can be performed
opportunistically over time and during multiple
visits. Indeed, every clinic visit to a primary care
provider should be seen as an opportunity to screen
for any physical, psychological, or social problems.6 7 When one considers that 80% of the Hong Kong
population have consulted a primary care provider in
1 year, with a mean of eight primary care visits per
year,8 there is ample opportunity for primary care
providers to discuss preventive care services.
Evidence-based preventive care for older adults
The core document2 provides up-to-date evidence-based
recommendations for preventive care
of older adults in primary care setting. These
recommendations can be categorised into various
health domains, including vaccination, adoption of
a healthy lifestyle, dental health, chronic diseases,
cancers, functional disability, mental disorders,
polypharmacy and adverse drug reactions, and
assessment of social network and support. A
summary of the recommendations is listed in
Table 1.9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 Although the recommendations aim to
support primary care providers in decision-making,
the care provided for each patient should also be
individualised.
Practice of evidence-based recommendations for older adults with different functional capacity
Older adults vary in their needs and functional
capacity. In a healthy active older adult, the emphasis
will often be on health promotion and disease-prevention
activities. At the other extreme, a frail
older adult with additional special needs will require
a comprehensive assessment and formulation of an
individualised care plan. The needs and condition
of an older adult may also change over time. It is
not uncommon to see a healthy active older adult
suddenly becomes disabled following an untoward
event.
In order to formulate a personalised care
plan and effectively implement the evidence-based
recommendations, three categories of functional
capacity of older adults have been proposed—independent with no known chronic diseases,
independent with chronic diseases, and older adults
with disabilities.
For all older adults and as far as applicable,
promotion of a healthy lifestyle and early
identification and appropriate management of risk
factors—such as unhealthy diet, physical inactivity,
and tobacco use—should form the cornerstone in
prevention or management of chronic diseases. A
healthy lifestyle is known to be positively associated
with better physical and mental health as well as
longevity, reduced risk of chronic diseases, and
more quality-adjusted life years.33 34 Thus promoting
a healthy lifestyle should be one of the main focuses
in healthy ageing.
For older adults of all functional stages, a
healthy lifestyle and modification of behavioural risk
factors should be promoted as much as is practical.
Table 2 provides a summary of the recommendations.
Independent with no known chronic disease
Staying active and healthy is essential to the quality
of life. The functional decline that occurs with ageing
may be due, at least in part, to lifestyle, behaviour,
diet, and the environment, which are all modifiable
factors.35
The primary objective for this category of older
adults is to maintain optimal functional capacity
and prevent or delay the development of chronic
disease, thus helping to extend a healthy active life.
In addition to health education and promotion, a
systemic health assessment and early identification
of chronic diseases are important.
The recommended items for assessment in this
category of older adults are listed in Table 3. Details
of preventive care can be found in the respective
chapter of the core document2 and/or module
quoted in brackets.
Table 3. Recommendations on preventive care for independent older adults with no known chronic diseases
Independent with chronic diseases
Older adults with chronic diseases vary in clinical
heterogeneity, number of chronic conditions,
severity of illness, and functional limitations.
Chronic diseases exert a synergistic effect such that
the combined disabling effect of different diseases
is greater than the combined effect of each.36 As
the number of chronic diseases in an individual
increases, the risk of mortality, poor functional
status, unnecessary hospitalisations, and adverse
drug events also increases.37 38 39 Multiple chronic
diseases can be accompanied by loss of function,
reduced independence, and increased risk of
depressive illness. These subsequently contribute to
frailty and disability.37 40
The objectives of preventive services in these
older adults are to appropriately manage their
chronic diseases with reference to both secondary
and tertiary prevention, as well as to maintain
functional independence. The recommendations on
preventive care for independent older adults with
chronic diseases are summarised in Table 4. Details
about preventive care can be found in the relevant
chapter of the core document and/or module quoted
in brackets.2
Older adults with disabilities
Older adults who suffer multiple debilitating diseases
(such as stroke, dementia, or arthritis) are likely to
face disabling barriers that inhibit or prevent their
integration into the community. Chronic pain is also
common in this group of older adults and invariably
jeopardises physical, psychological, and social
wellbeing.
The approach to this group is early intervention
to prevent further loss of function, so as to maintain
optimal functional capacity and improve quality
of life, and also facilitate integration into society
for those who have relatively mild disability. A
comprehensive assessment should be offered to
this group of older adults with complex needs, and
should encompass physical, psychological, and social
aspects of care (eg ability in self-care, hearing and
visual impairment, incontinence, falls, depression,
cognitive impairment, malnutrition, polypharmacy,
social support, and carer stress).
The recommendations on preventive care for
older adults with disabilities are listed in Table 5.
Details about preventive care can again be found in
the relevant chapter of the core document and/or
module quoted in brackets.2
The two-page summary
A 2-page summary (Fig) has been developed to
provide a quick reference for primary care providers
on preventive care for older adults. It provides a
summary of the evidence-based recommendations
for preventive activities and the practice of
recommendations for older adults with different
functional capacities. The relevant chapter of the
preventive care is stated in the summary for further
information and supporting evidence. It can also be
downloaded from the Primary Care Office website
(http://www.pco.gov.hk/english/resource/files/Summary_page_older_adult.pdf).

Patient education materials
In a busy clinic, patient education material is an
effective means to deliver preventive care information
to patients and their carers. The resources related to
the health care of older adults are available in Annex
3 of the core document.2 These resources provide
information for the local community and help
primary care providers coordinate care with other
professionals and specialists. Families can also be
put in touch with community-based services. With
appropriate care, older adults can achieve optimum
health and improve their quality of life.
Conclusion
Effective preventive care of older adults can be
achieved through health education and promotion,
prevention and monitoring of diseases, and reduction
of functional disabilities. Primary care providers
play an important role in providing patient-centred,
comprehensive, continuing, and coordinated
preventive care to older adults in the community. In
addition, continued efforts of different health care
providers, professional organisations, social service
agencies, and all stakeholders are needed to provide
a supportive environment for active and healthy
ageing. It is hoped that through the development
and promotion of this reference framework, more
emphasis can be placed on preventive care in older
adults. This will improve their health and promote
healthy ageing.
