AGE-FRIENDLY CARE QUALITY · LONG-TERM CARE QUALITY

Last reviewed: October 2026

An older person can live alone and feel content, independent and closely connected to family, neighbors and friends. Another can live in a busy multigenerational household and still feel that nobody really listens to them. Someone recovering from a stroke may previously have had an active social life but gradually stop seeing friends because leaving the house has become difficult. A resident in long-term care may be surrounded by staff and other residents throughout the day yet still miss the one or two relationships that gave life meaning.

These situations illustrate an important distinction: being alone, being socially isolated and feeling lonely are not the same thing. Treating them as though they were interchangeable can lead to the wrong response. A person who values solitude does not necessarily need more activities. Someone who participates in several groups may still feel profoundly lonely. And a person with strong emotional relationships may nevertheless become practically isolated because mobility problems, hearing loss, inaccessible transport or other barriers prevent participation in everyday life.

WHO's Commission on Social Connection has brought much greater international attention to this issue. Its 2025 flagship report places social connection alongside other important determinants of health rather than treating it as a lifestyle extra. WHO's latest estimates suggest that around 11.8% of older people globally experience loneliness. WHO also summarizes evidence suggesting that approximately one in four older people are socially isolated, although population data on social isolation are less complete and come from a more limited range of countries. These are global estimates and should not be presented as prevalence figures for older people in Viet Nam.

For Viet Nam, the practical question is therefore not simply:

“Does this older person live alone?”

A more meaningful question is:

“Does this person have the relationships, support, opportunities for participation and sense of belonging they need—and is the care system helping them maintain those connections as their health and circumstances change?”

Social isolation, loneliness and social connection are different things

WHO describes social connection through three dimensions. Structure refers to the number and type of relationships and social roles a person has and how often they interact with others. Function concerns what those relationships provide, including practical and emotional support. Quality refers to how those relationships are experienced: supportive and satisfying, or strained, conflictual or harmful.

Social isolation is primarily objective: having too few relationships, roles or interactions. Loneliness is subjective: the distressing feeling that arises when the social connection a person has does not match the connection they want or need.

This distinction immediately changes how care should be designed. Someone with a small social network may be completely satisfied with it. Another person may speak to many people every day but feel that none of those interactions offers intimacy, understanding or belonging.

Living alone can therefore be a useful marker of possible vulnerability, but it is not a diagnosis of loneliness. Likewise, living with family can provide substantial practical and emotional support, but it does not guarantee meaningful connection. Some family relationships are warm and protective; others may involve conflict, neglect, control or abuse.

A quality care system needs to understand the person's actual social world, not infer it from household composition.

Social connection is part of healthy aging

Social connection fits naturally within WHO's healthy-aging framework. Functional ability is not defined only by being able to walk, eat or manage medicines. It includes the abilities to build and maintain relationships and to contribute to society, alongside meeting basic needs, remaining mobile, and learning, growing and making decisions.

This matters because social participation and health are deeply interconnected. Hearing loss can make conversation exhausting. A fall may create fear of leaving home. Urinary incontinence may lead someone to avoid social events. Chronic pain can make a short journey to a community activity feel impossible. Visual impairment can interfere with travel, reading or recognition of familiar faces. Depression can reduce motivation to participate, while social disconnection may in turn worsen psychological well-being.

WHO's updated 2026 guidance on mental health in older adults identifies loneliness and social isolation as important risk factors for mental-health problems and emphasizes meaningful social activity as part of promoting well-being in later life.

The direction of these relationships is not always simple. Much of the evidence is observational. Poor health can contribute to social disconnection, while social disconnection may itself be associated with poorer health. It is therefore more accurate to speak of interacting risks and associations rather than assume that loneliness directly causes every adverse outcome in an individual.

The implication for quality care is nevertheless clear: social connection should not disappear from the care plan simply because a medical diagnosis seems more urgent.

What does the Vietnamese evidence actually tell us?

Contemporary nationally representative evidence specifically focused on loneliness and social isolation among older people in Viet Nam remains limited, particularly when common internationally standardized measures are required. Existing studies therefore need to be interpreted according to the populations and outcomes they actually examined.

A particularly relevant study published in 2026 used data from the Vietnam Health and Aging Study to examine living arrangements, family resources and cognitive functioning. Older adults living alone appeared particularly vulnerable. Compared with people living with both a spouse and children, they had poorer cognitive functioning, while household resources, social engagement, loneliness and psychological distress formed part of the statistical pathways linking living arrangements with cognition.

The study is important because it places loneliness and social engagement within a specifically Vietnamese family and household context. It does not, however, prove that living alone causes cognitive decline, and it should not be interpreted as a nationally representative prevalence survey of loneliness.

The same research illustrates why household composition alone is an incomplete measure of social connection. Older adults living only with a spouse showed lower social engagement than those living with a spouse and children, but they did not necessarily report greater loneliness. Different living arrangements may therefore affect different forms of social resource in different ways.

Another large Vietnamese analysis published in BMJ Open in 2025 used weighted data from the 2022 Viet Nam Ageing Survey, covering 3,183 people aged 60 years and older across 12 provinces. Lack of social participation was independently associated with both basic and instrumental functional limitations after adjustment for other factors. Because the survey was cross-sectional, it cannot determine whether reduced participation contributed to functional disability, functional disability restricted participation, or both.

The evidence therefore supports a cautious but important conclusion: social participation, living arrangements, psychological well-being and function are already demonstrably interconnected in Vietnamese older populations, but high-quality national evidence specifically measuring loneliness and social isolation remains incomplete.

Viet Nam now has a stronger policy foundation for recognizing social needs

An important development in 2026 is that social connection is no longer only an abstract healthy-aging concept within Vietnamese older-person policy.

Decision No. 1976/QĐ-BYT of 1 July 2026, which issued professional guidance on caring for older people at home and in the community, explicitly states that older people should be supported to adapt to psychological and physiological changes, improve physical and mental health and maintain social connection.

The guidance goes further. Its assessment of social-support needs specifically asks whether the older person feels lonely, alongside questions about housing and financial difficulties. It recognizes that retirement, illness, reduced participation, bereavement and changing family arrangements can alter a person's social roles and relationships.

Decision 1976 also describes practical community mechanisms. Older-person care clubs can provide health education, cultural and recreational activities, exercise and other locally appropriate forms of participation. Community day-care points can support older people with reduced self-care capacity while also providing cultural, recreational and physical activities.

The guidance also addresses older people who are alone, need care at home and have no available caregiver. In such circumstances, care may be provided by people assigned to undertake home care by the commune-level health station. This situation should not be confused with loneliness: having no available caregiver is an objective care-support problem, while loneliness is a subjective experience. One person may experience both, either one, or neither.

Circular No. 34/2026/TT-BYT provides an implementation pathway for this community-care architecture. It directs provincial health authorities, commune-level health stations and relevant community personnel to use Decision 1976 in training and older-person care activities. It also incorporates development of community clubs with older-person health-care content into programme monitoring. The national target is for 90% of communes, wards and special zones to have at least one club with older-person health-care activities by 2030.

That figure is an implementation target, not current national coverage.

Nor does this policy architecture mean that Viet Nam already has a universal loneliness-screening and intervention service. What it does provide is a much stronger foundation for health and community services to recognize social needs and incorporate participation into older-person care.

Participation should be supported, but should remain a choice

The current consolidated Law on Older Persons provides another important foundation. It recognizes the right of older people to decide whether to live with their children and grandchildren or to live separately according to their wishes. It also requires conditions to be created for older people to participate in cultural, educational, physical, recreational, tourism and other activities.

This leads to an important principle:

Social connection should be supported without turning social participation into an obligation.

Living alone may be a deliberate and satisfying choice. Wanting time alone is not a pathology. An older person who declines a community club should not automatically be regarded as socially unhealthy.

The objective is not maximum social contact. It is to enable the type and level of connection the person values, while recognizing when unwanted isolation, loneliness or lack of practical support begins to affect health, function or quality of life.

Recognition therefore needs to go beyond asking whether someone lives alone. A useful conversation can explore three dimensions.

Structure: Who matters in this person's social network? How often do meaningful interactions occur? Have important relationships recently been lost?

Function: Is there someone the person can call when help is needed? Is emotional support available as well as practical support? Is there someone who can accompany them to an appointment or help in an emergency?

Quality: Does the person feel understood, valued and respected? Are important relationships satisfying, or dominated by conflict, obligation, fear or control?

Assessment should also explore participation. Which activities and roles matter to the person? Have they stopped doing them? If so, why?

The answer may be loneliness, but it may also be hearing loss, pain, urinary urgency, fear of falling, lack of transport, inaccessible buildings, financial difficulty, caregiving responsibilities or simply the absence of an activity that feels meaningful.

The most useful question is often not:

“How often do you see people?”

It is:

“Are you able to spend time with the people and do the things that matter to you?”

Social disconnection should not be confused with depression, dementia or lack of motivation

Loneliness and depression frequently coexist, but they are not the same condition.

A lonely person may not have depression. Someone with depression may have a large and apparently supportive social network. Depression may cause withdrawal, while prolonged loneliness may increase vulnerability to depressive symptoms.

The same distinction applies to dementia. Cognitive impairment can make communication and participation harder, but loneliness should not automatically be attributed to dementia. Withdrawal in a person with dementia may instead reflect hearing loss, pain, fear, depression, an overstimulating environment or difficulty following conversation.

When someone stops participating, one of the most useful questions is therefore:

“What changed?”

Sometimes the answer is social. Sometimes it is clinical. Often it is both.

Function and environment can quietly determine whether someone remains connected. An older person may want to attend a neighborhood activity but be unable to climb the steps at the entrance. Another may continue attending family meals but understand little of the conversation because hearing loss is untreated. Someone may stop visiting friends because they no longer feel safe crossing a busy road. A person discharged after a hip fracture may lose much of their former social life simply because transport and transfer arrangements were never reconsidered.

A 2026 mixed-methods systematic review of 99 studies involving community-dwelling older adults found that better physical health and function, psychological resources, supportive interpersonal networks and community opportunities generally facilitated social participation. Functional limitations, depression, anxiety and loneliness were generally associated with lower participation, while poor accessibility and limited opportunities created additional barriers.

This is highly relevant to older-person care. Someone may not need encouragement to “be more social.” They may need rehabilitation, hearing support, continence care, pain treatment, safer transport or an accessible community venue.

Social participation is therefore partly a health-care issue and partly an environmental and accessibility issue.

Hospitalization and care transitions can disrupt a person's social world

An older person can enter hospital with a strong social routine and leave with much less of one.

Acute illness may interrupt visits to friends, religious activities, exercise groups, clubs or informal neighborhood routines. Bed rest and functional decline can make previously easy activities difficult. Hearing aids or glasses may be unavailable during admission. Delirium can disrupt communication. Family members may assume that prolonged rest is needed after discharge and unintentionally narrow the person's world even further.

Hospitals do not intend to create social isolation, but discharge planning often concentrates on medicines and medical appointments while paying less attention to whether the person can resume the relationships and roles that previously supported daily life.

A functional discharge assessment should therefore consider more than walking and self-care. Will the person return to a home where meaningful contact is available? Can they physically reach activities that previously mattered? Is transport available? Are hearing, vision or communication problems limiting connection? Does the discharge plan assume that a family member is available when that support does not actually exist?

A person may be medically ready for discharge yet socially vulnerable.

The same issue arises when someone moves from hospital to rehabilitation or from home into long-term care. A transition may separate the person from a spouse, familiar neighbors, friends or established community roles even when the new setting provides excellent clinical care.

Good transition planning should therefore ask: Who are the important people in this person's life? Which routines and activities matter? How will those relationships continue? What support is needed to make that possible?

Facility-based activities should not simply replace the person's existing social world.

Continuity of care includes continuity of relationships.

Community support should begin with what matters to the person

One older person may value a local exercise group. Another may care deeply about religious life. Someone else wants to look after grandchildren, teach younger family members, garden, play music, continue part-time work or simply share coffee with familiar neighbors.

Meaningful participation is not defined by the activity itself. It is defined by what that activity means to the person.

Decision 1976/QĐ-BYT creates useful community platforms through older-person care clubs and day-care points, while Circular 34/2026/TT-BYT provides an implementation route for expanding such community activity.

But establishing a club does not automatically reduce loneliness. A venue may be inaccessible to someone with severe mobility limitations. A person with hearing loss may feel excluded in a noisy group. Someone living with dementia may benefit more from a smaller supported activity than from a large event. An older person grieving a spouse may need a very different response from someone whose primary barrier is lack of transport.

The quality question is therefore not:

“Does the community have an older-person club?”

It is:

“Can the people who need connection actually access something meaningful to them?”

Nor is more social activity always the answer. Some people remain lonely despite frequent activities because those interactions are not the relationships they value. Others prefer a small number of close relationships. Some value solitude and experience pressure to participate as intrusive rather than supportive.

A 2025 systematic review identified 35 randomized trials involving 5,291 older adults testing interventions that targeted mechanisms including social behavioral activation, cognitive engagement or restructuring, distress tolerance and acceptance of aging. Across the studies included in pooled analyses, loneliness improved overall, but variation between studies was extremely high. The size and consistency of effects therefore differed substantially across interventions, populations and delivery approaches.

The practical lesson is that the response should follow the cause and lived experience of disconnection, not a generic loneliness protocol.

A recently widowed person may need emotional companionship and time to rebuild valued relationships. Someone isolated because of mobility impairment may need rehabilitation and transport. Someone experiencing depression may need mental-health care before social activity becomes meaningful.

There is no single “loneliness intervention.”

Digital connection can help, but technology is not the relationship

Digital technology can be useful when family members live far away or physical mobility limits face-to-face contact.

A 2026 systematic review and meta-analysis of 16 randomized trials involving 1,179 older adults found that information-technology-based social-interaction interventions were associated overall with lower loneliness. Interventions involving interpersonal interaction showed stronger effects in some subgroup analyses than predominantly human–computer interaction, and family involvement also appeared potentially important. The authors nevertheless cautioned that study heterogeneity and methodological limitations require careful interpretation.

Digital access is also not simply about giving someone a smartphone.

Vision, hearing, manual dexterity, cognition, affordability, digital literacy, internet reliability and concerns about fraud or scams can all determine whether technology creates connection or frustration. Some people need initial training and continuing support.

Digital contact should not automatically be treated as equivalent to the relationship a person wants. A weekly video call may be deeply meaningful for one older adult and feel inadequate to another.

The goal is to use technology to extend meaningful human connection, not replace it.

Long-term care needs connection, choice and safety, not simply an activity calendar

A residential facility can offer activities every day and still have lonely residents.

One resident may attend group exercise but deeply miss their spouse. Another may sit in a communal room for hours without being able to follow conversation because of hearing loss. Someone living with dementia may be physically surrounded by people while experiencing very little meaningful interaction. Another resident may dislike group activities entirely but value a long conversation with one staff member or another resident.

Quality long-term care therefore needs to move beyond counting attendance.

Staff should understand who matters to each resident, which relationships and roles they value, whether communication support is needed, whether important family and friendship ties are being maintained and whether the person actually feels connected.

The physical environment matters as well. Private rooms can support dignity and privacy but may reduce spontaneous interaction if communal spaces are difficult to reach or unwelcoming. Shared environments may facilitate contact but become overwhelming for people with sensory or cognitive impairment.

The answer is not one universal design. It is an environment that offers choice between privacy and connection.

Connection must also be safe. Social relationships can be supportive, but they can also be controlling, exploitative or abusive. An older person may depend heavily on a relative who is simultaneously financially exploiting them. Another may intentionally avoid contact with a family member because the relationship feels unsafe.

Safeguarding and social connection therefore need to work together.

The goal is meaningful and safe connection, not contact at any cost.

Caregiver capability also matters. Family caregivers often arrange transport, maintain visits, operate hearing or communication technology and preserve community routines. But the primary caregiver can gradually become the older person's only social contact.

When that happens, both people may become vulnerable. The older person's social world depends heavily on one relationship, while the caregiver may lose much of their own social life and experience increasing burden.

Integrated care should therefore ask whether the older person's network extends beyond one caregiver and whether the caregiver has enough support to sustain their role.

Creating a social environment around an older person is different from asking one relative to provide everything.

Measurement should distinguish activity from connection

A quality system needs to measure the right thing.

Counting how many people live alone may help identify possible vulnerability, but it does not measure loneliness. Counting club attendance measures participation, not belonging. Counting family visits says little about the quality of those relationships.

Measurement should therefore distinguish at least four related but different issues: objective social isolation, subjective loneliness, meaningful participation and available social support.

WHO's structure–function–quality model provides a useful foundation. Services can examine whether relationships and interactions exist, whether practical and emotional support is available and whether important relationships are experienced as positive and satisfying.

At an organizational level, useful quality measures could include whether social-support needs are assessed, whether identified loneliness or isolation leads to an individualized response, whether hearing, mobility or environmental barriers to participation are addressed, whether important relationships and routines are documented during care transitions, and whether the person's own experience of connection improves.

For long-term care, one of the most meaningful questions may simply be:

“Does this resident have opportunities to spend time with the people and take part in the activities that matter to them?”

That is a very different measure from the number of activities on a monthly calendar.

A practical social-connection framework for Viet Nam

Viet Nam does not need to wait for a stand-alone national loneliness strategy before strengthening social connection within older-person care. WHO's social-connection framework, the Healthy Ageing model, ICOPE 2nd Edition, the Law on Older Persons, Decision 1976/QĐ-BYT and Circular 34/2026/TT-BYT already provide useful building blocks.

Recognition should distinguish living alone, social isolation and loneliness rather than treating them as equivalent. Assessment should examine the structure, function and quality of relationships together with available social support, participation and the roles and activities the person values.

Clinical and functional assessment should identify potentially modifiable barriers such as hearing or vision impairment, pain, falls risk, mobility limitations, continence problems, depression, cognitive impairment and fatigue. Environmental assessment should consider transport, accessibility, neighborhood safety, digital access and financial barriers.

Individualized response should match the reason for disconnection. Some people need practical support to leave home; others need emotional support, psychological treatment, communication assistance or opportunities for meaningful participation. Community groups, befriending, volunteering, intergenerational activities and digital communication may all have roles, but none should be offered mechanically.

Transition planning should protect important relationships and valued routines when someone moves between hospital, rehabilitation, home and long-term care. Caregiver support should strengthen the social environment without making one family member solely responsible for it. Long-term care governance should treat meaningful connection and participation as quality outcomes rather than optional recreation.

Finally, measurement and learning should examine whether the person actually feels more connected and can participate in what matters to them—not simply whether an activity was offered.

These elements need to work together. A community club cannot compensate for an inaccessible building. A video call cannot compensate for untreated hearing loss. Frequent family contact cannot compensate for an abusive relationship. An excellent rehabilitation program can still leave someone socially isolated if they return home unable to reach the people and activities that previously mattered.

And simply telling a lonely older person to “go out more” is not an integrated care plan.

From social contact to belonging and participation

For an older person, meaningful social connection may mean having someone who listens without rushing, being able to see an old friend, continuing to contribute to the family, returning to a familiar neighborhood activity after illness, having a valued role in the community or simply knowing that there is someone to call when help is needed.

For families, good support means helping connection without assuming that family presence alone solves loneliness. For hospitals, it means recognizing that major illness can disrupt a person's social world as well as physical function. For home and community services, it means removing barriers and enabling participation that is genuinely meaningful. For long-term care, it means creating opportunities for relationships and belonging while respecting privacy, preference and autonomy.

WHO's healthy-aging framework provides a useful reminder: the ability to build and maintain relationships and contribute to society is part of functional ability itself.

As Viet Nam develops more age-friendly, integrated and long-term care, the question should therefore not simply be:

“Is this older person living alone?”
