Supporting Safe Hydration in Home-Based and Residential Long-Term Care in Viet Nam: Individual Fluid Needs, Consistent Drinking Support and Timely Escalation

Supporting Safe Hydration in Home-Based and Residential Long-Term Care in Viet Nam: Individual Fluid Needs, Consistent Drinking Support and Timely Escalation

An older woman living in a residential care facility has a glass of water beside her throughout the morning. Staff refill it when necessary, and drinking water is readily available. Yet by lunchtime, she has consumed very little. She finds the glass difficult to hold and does not want to ask for assistance every time she feels thirsty. She is also worried about needing help to reach the bathroom.

From the facility's perspective, water has been provided. From the resident's perspective, drinking remains difficult.

A similar situation may occur at home. An older man receives a short care visit in the morning, when someone prepares breakfast and leaves a drink nearby. During the afternoon, he becomes tired and remains seated for several hours. The drink is still there when his family returns, but nobody knows how much he has consumed.

These situations illustrate an important distinction: making drinks available is not the same as ensuring that an older person can access and consume suitable fluids safely throughout the day.

Adequate hydration supports normal physiological function and everyday wellbeing. Insufficient fluid intake can contribute to low-intake dehydration, while acute illness, increased fluid losses, and certain medications may create additional risks. Older people can be particularly vulnerable because of reduced thirst sensation, functional limitations, cognitive difficulties, or dependence on others for assistance.

At the same time, encouraging more drinking is not always appropriate. Some people require individualized fluid restrictions or other clinical arrangements because of their health conditions.

For home-based and residential long-term care services in Viet Nam, safe hydration support involves understanding individual needs, making drinking practically possible, recognizing changes that require professional assessment, and ensuring that agreed support is delivered consistently.

The objective is not simply to provide water or achieve a standard daily volume. It is to help each person maintain appropriate hydration while respecting their abilities, preferences, clinical needs, and right to participate in care decisions.

Hydration Is an Everyday Care Responsibility With Clinical Implications

Hydration is often addressed alongside nutrition, but the practical challenges of drinking deserve attention in their own right.

An older person may eat adequately while drinking too little. Another may enjoy beverages but be unable to reach them independently. Someone who drinks comfortably during meals may consume very little between them.

These differences matter because hydration depends on more than the availability of water or a person's willingness to drink.

The European Society for Clinical Nutrition and Metabolism (ESPEN) addresses these concerns in its 2022 Practical Guideline: Clinical Nutrition and Hydration in Geriatrics. The guideline recognizes low-intake dehydration as an important risk in older people and recommends individualized approaches involving accessible drinks, personal preferences, practical assistance, and appropriate assessment.

The guideline also distinguishes everyday drinking support from clinical diagnosis and treatment. Helping someone obtain and consume suitable beverages may form part of routine care, while diagnosing dehydration, determining its cause, and prescribing treatment require appropriate clinical expertise.

The Australian Aged Care Quality and Safety Commission reinforced these responsibilities in a clinical alert published on June 18, 2026.

The alert followed a coronial investigation in South Australia involving the death of an older residential care resident from acute renal failure caused by severe dehydration. The coroner found that the death was preventable and identified the absence of an adequate system for monitoring fluid intake and recognizing the seriousness of dehydration risk.

The Commission emphasized the importance of identifying vulnerable residents, implementing appropriate preventive arrangements, monitoring changes, and escalating concerns promptly.

The lesson extends beyond any single event. A care organization can have drinking water readily available and still fail to recognize that someone is unable to consume enough.

However, not every episode of dehydration is preventable through routine drinking support, and a diagnosis of dehydration does not automatically establish that care was inadequate. Medical conditions, acute illness, and other circumstances can contribute.

The responsibility of the organization is to recognize foreseeable vulnerabilities, deliver appropriate support within its capabilities, and respond when concerns arise.

Understanding Individual Fluid Needs

Older people do not all require the same amount of fluid. Requirements vary according to body size, activity, environmental temperature, dietary intake, medical conditions, medications, and ongoing fluid losses.

Water comes from both beverages and food. This distinction matters when interpreting general recommendations because a figure describing total daily water intake is not necessarily equivalent to a target for drinking.

ESPEN's 2022 practical guideline recommends that older women generally be offered at least 1.6 liters of drinks each day and older men at least 2.0 liters, unless a clinical condition requires a different approach.

These are general recommendations concerning beverages offered, not universal prescriptions for the amount every individual must consume. Offering the recommended volume also does not establish how much a person actually drinks or whether their hydration status is adequate.

Viet Nam's Ministry of Health issued Decision No. 1976/QĐ-BYT on July 1, 2026, promulgating professional guidance on caring for older people at home and in the community.

Section 3.1.5 addresses adequate hydration and recognizes that thirst sensation may decline with age. The guidance refers to a general total daily water requirement of approximately 1.5–2.0 liters, with adjustments according to health conditions and professional advice.

The ESPEN recommendation and the Vietnamese reference should not be treated as interchangeable numerical requirements. They describe water needs differently and serve as general points of reference within their respective guidance.

Neither should be converted into a universal drinking target for every older person.

Some individuals with heart failure, advanced kidney disease, or particular disorders of fluid and electrolyte balance may need individualized limits or monitoring determined by their treating healthcare professionals.

These diagnoses do not automatically mean that everyone affected needs fluid restriction. The appropriate arrangement depends on the person's clinical circumstances.

Other individuals may require reassessment when fever, vomiting, diarrhea, increased urination, hot weather, or other conditions alter their fluid needs.

Care workers should understand relevant instructions in the person's care plan but should not independently introduce, remove, or modify medically prescribed fluid restrictions.

The practical goal is to support appropriate fluid intake for the individual rather than encourage everyone to drink as much as possible.

Why Drinking Can Be Difficult Even When Water Is Available

The reasons for inadequate drinking are often ordinary and easily overlooked.

A resident may be unable to pour water from a heavy container. Another may find a cup difficult to hold because of weakness, tremor, arthritis, or reduced hand function. Someone with poor vision may not notice that a drink has been placed nearby.

A person with limited mobility may see a glass on the table but be unable to reach it comfortably. Others may forget to drink, feel less thirsty than before, or lose interest in beverages during illness.

The environment can either reduce or increase these difficulties.

A lightweight cup with a suitable handle may allow someone to drink independently. A familiar container may be easier to use than unfamiliar equipment. For another person, an adapted drinking aid recommended by an appropriate professional may be necessary.

Preferences also matter. Some people enjoy warm tea, while others prefer cool water or another suitable beverage. Offering reasonable choices can make drinking more acceptable than repeatedly insisting on plain water.

Concerns about continence may create additional barriers.

An older woman may deliberately reduce her fluid intake because she worries about urinary leakage. A resident may avoid drinking in the evening because assistance with toileting is difficult to obtain. Someone receiving home care may drink less while alone because they fear needing to walk to the bathroom without help.

These behaviors should not automatically be described as noncompliance.

They may reflect understandable concerns about independence, privacy, mobility, or the reliability of assistance. A person may appear reluctant to drink when the underlying problem is that asking for help feels embarrassing or burdensome.

Recognizing these barriers changes the question from whether water has been provided to whether the person can drink comfortably, safely, and with reasonable independence.

Turning Drinking Opportunities Into Consistent Support

Reminding someone to drink is helpful only when the person can act on the reminder.

For an older person who drinks independently, appropriate support may involve keeping suitable beverages within reach, offering choices, and providing regular opportunities throughout the day. Someone with greater functional limitations may require help preparing a drink, positioning an appropriate cup, or receiving direct assistance.

These arrangements should reflect the person's assessed needs, preferences, and any relevant clinical instructions.

The UK Health Security Agency and Department of Health and Social Care published updated infection prevention and control guidance for adult social care on October 28, 2026.

Its section on the fundamentals of care emphasizes regular opportunities for drinking, personalized beverage choices, practical assistance, and integrating hydration into normal daily routines.

The guidance covers adult social care settings in England, including residential and home-based services. Its principles are useful for quality improvement elsewhere, although its specific regulatory context does not automatically apply in Viet Nam.

The relevance to everyday care is straightforward.

A resident may receive appropriate assistance during breakfast and lunch but have limited opportunities to drink between meals. Another may be offered a beverage during every staff round without anyone checking whether the person can actually consume it.

In home-based care, the challenge may be more complicated because workers are present only during scheduled visits.

Leaving a drink within reach may be helpful, but it does not guarantee adequate intake during the hours when the person is alone.

Where ongoing assistance is required, the older person, relevant family members, and service providers should agree on realistic arrangements. These may involve support during scheduled visits, assistance from available caregivers, or additional services when the person's needs cannot otherwise be met.

A care plan should not assume that family members will always be available unless those responsibilities have been discussed and accepted.

Consistency also depends on communication. If one worker notices that a resident is drinking substantially less than usual, the concern needs to reach the person responsible for reviewing it rather than disappear at the end of the shift.

Reliable hydration support does not require identical drinking schedules for everyone. It requires suitable opportunities and assistance for people who would otherwise struggle to drink.

Supporting Choice, Dignity, and Continence Needs

Drinking is an ordinary part of daily life, and the way assistance is provided can affect a person's comfort and dignity.

Older people should be involved in decisions about preferred drinks, usual routines, and the help they receive, as far as their circumstances and lawful decision-making arrangements permit.

A resident may prefer tea in the morning, water during meals, and another suitable beverage later in the day. Someone may wish to use a familiar cup rather than specialized equipment. Another may prefer drinking in a quieter setting.

These preferences can make support more acceptable and preserve a sense of control.

However, personal choice must also be considered alongside relevant clinical requirements. Certain drinks or fluid volumes may need adjustment because of medical advice, swallowing difficulties, dietary restrictions, or other health considerations.

Staff should communicate these requirements respectfully and seek professional clarification when the person's preferences and clinical instructions appear difficult to reconcile.

Care should also avoid coercion.

Repeatedly pressuring someone to drink without understanding their concerns may create distress. A refusal may reflect nausea, discomfort, swallowing difficulty, dislike of the beverage, or anxiety about needing assistance with toileting.

Where possible, staff should explore the reason, offer suitable alternatives within the care plan, and seek professional assessment when reduced intake raises a health concern.

Continence support deserves particular attention. Someone who avoids drinking because they cannot obtain timely assistance to use the bathroom may need a review of toileting arrangements rather than additional reminders alone.

Better access to assistance, suitable continence products, and respectful communication may help address the practical concern.

The person's rights and lawful choices remain important. Where serious clinical risk, consent, or decision-making questions arise, appropriately qualified professionals should be involved under the relevant Vietnamese legal framework.

Safe hydration support should preserve independence and dignity while ensuring that potentially important health concerns are not ignored.

Safe Drinking Support Must Account for Swallowing Difficulties

Not everyone who needs assistance with drinking can safely consume ordinary fluids.

Some older people experience dysphagia, or swallowing difficulty, which may increase the risk of choking or aspiration. Others may have conditions affecting alertness, posture, or their ability to manage oral intake safely.

In these circumstances, simply offering more drinks may be inappropriate.

The person's swallowing arrangements should follow relevant clinical assessment and instructions from appropriately qualified healthcare professionals. These may address suitable fluid consistency, positioning, drinking aids, assistance, and other individualized measures.

Care workers should not independently prescribe thickened fluids, change an established fluid consistency, or assume that a particular technique is safe for everyone.

A person who coughs repeatedly while drinking, has difficulty swallowing, or develops new concerns about oral intake may require professional assessment.

Where modified-consistency fluids have been prescribed, staff should also pay attention to whether the person is able and willing to consume them.

Someone may drink less because the available beverages are difficult to manage, unfamiliar, or unappealing. These problems should be communicated to the responsible healthcare professional rather than addressed through unauthorized changes.

The Ministry of Health's 2026 guidance for care at home and in the community includes practical content on supporting older people with difficulties eating and drinking.

This provides a relevant domestic professional reference, but the appropriateness of particular activities depends on the caregiver's role, training, competence, and the individual's needs.

Additional guidance is available in ESPEN's 2024 Guideline on Nutrition and Hydration in Dementia, which emphasizes individualized support, appropriate assistance, oral care, and monitoring for people living with cognitive impairment.

The guideline also distinguishes ordinary oral support from medical nutrition and hydration interventions, whose appropriateness depends on the person's condition, the stage of illness, and goals of care.

For residential and home-care organizations, the central responsibility is to recognize when routine drinking assistance is insufficient and ensure that appropriate professional support is obtained.

This article does not provide a swallowing assessment procedure or instructions for administering modified-consistency fluids, enteral fluids, or artificial hydration.

Recognizing Changes Without Attempting to Diagnose Dehydration

A reduction in drinking may indicate that something has changed in an older person's health or ability to manage daily activities.

Someone who normally enjoys regular drinks may suddenly decline them. Another person may become unusually tired, less interactive, or unable to handle a cup that was previously manageable.

An older person experiencing vomiting or diarrhea may have increased fluid losses while also consuming less.

These observations deserve attention, but they should not automatically be interpreted as proof of dehydration.

Clinical signs can be difficult to interpret in older adults. Dry mouth, dark urine, dizziness, fatigue, or reduced urine output can occur for several reasons. Importantly, the absence of these signs does not reliably exclude dehydration.

ESPEN's 2022 practical guideline advises against relying on common simple signs, including skin turgor, mouth dryness, weight changes, and urine color, as stand-alone methods for assessing low-intake dehydration in older adults.

The guideline supports appropriate clinical assessment, including laboratory evaluation when indicated.

Queensland Health's Dehydration and Subcutaneous Fluids clinical pathway similarly recognizes that no single clinical or laboratory feature reliably identifies dehydration in every older person.

There is also an important distinction between low-intake dehydration and fluid volume depletion associated with conditions such as significant vomiting or diarrhea.

These situations may involve different physiological disturbances and require different clinical assessments and management approaches.

Non-clinical care workers should therefore focus on observing and communicating relevant changes rather than diagnosing the type or severity of dehydration.

A useful report might explain that the person has consumed substantially less than usual, has experienced repeated vomiting, appears newly confused, or has shown another significant change from their usual condition.

This information can help a qualified healthcare professional determine what assessment is required.

Sudden confusion, marked deterioration, fainting, inability to maintain oral intake, or other potentially serious symptoms may require urgent medical attention. They should not be managed simply by encouraging the person to drink more.

Recognizing a concern early allows appropriate clinical decisions to be made before the situation becomes more serious.

Escalation Must Lead to Appropriate Professional Assessment

A hydration concern is not resolved merely because someone has recorded it.

A care worker may document that a resident drank very little during a shift. If nobody reviews the observation or determines whether action is needed, the record provides limited protection.

Residential and home-based care organizations need clear arrangements for communicating concerns to an appropriate professional or responsible person.

The response should consider the older person's condition, existing care plan, medical instructions, available clinical services, and urgency of the situation.

Persistently reduced intake may require contact with a healthcare professional for assessment or advice. Acute illness, significant fluid losses, or serious deterioration may require more urgent attention.

Where a person has a prescribed fluid restriction, workers should follow the current clinical plan rather than independently increasing intake.

Where swallowing is unsafe or the person cannot maintain oral intake, qualified professionals may need to assess options beyond routine drinking assistance.

The Australian Aged Care Quality and Safety Commission's June 2026 clinical alert emphasizes both prevention and prompt medical assessment when dehydration is suspected.

This reinforces the distinction between the responsibilities of everyday care providers and healthcare professionals.

Care staff can observe changes, provide agreed assistance, communicate relevant information, and help arrange access to appropriate healthcare. Diagnosis, decisions about clinical monitoring, and treatment remain within the responsibilities of appropriately qualified and authorized healthcare professionals.

Organizations should also establish what happens when the first person contacted is unavailable or a concern remains unresolved.

Where the situation is urgent, workers must have access to appropriate escalation or emergency arrangements rather than relying on a single contact who may not respond.

Effective escalation is demonstrated when information reaches an appropriate decision-maker and necessary action follows, not simply when a message has been sent.

Recording Fluid Intake Without Creating Unnecessary Paperwork

Fluid intake records can help identify patterns that are difficult to recognize from memory alone. However, recording should be proportionate to the person's assessed needs and the purpose of monitoring.

Some older people may require only ordinary observation and periodic review. Others, particularly those experiencing reduced intake, acute illness, significant dependency, or specific medical conditions, may need more structured monitoring.

Where fluid intake charts are used, staff should distinguish drinks offered from drinks actually consumed.

A full glass placed beside a resident does not show that the person drank it. Recording that assistance was offered is not the same as recording the amount consumed.

Even estimates of consumed volumes may be inaccurate, particularly when several caregivers are involved or drinks are taken gradually over time.

Records should therefore be interpreted with caution and should not replace clinical assessment.

Australia's strengthened Aged Care Quality Standards, particularly Outcome 5.5 on the safety of clinical care services, address identifying, monitoring, and managing clinical risks that include nutrition, hydration, swallowing, and related concerns.

The accompanying guidance addresses monitoring and documenting fluid intake and output for older people assessed as being at risk of or experiencing dehydration.

These provisions apply within the Australian regulatory framework. They should not be presented as a universal requirement for every home-care worker or residential facility in Viet Nam.

In Vietnamese care organizations, the decision to use structured fluid monitoring should reflect individual needs, relevant clinical instructions, and the provider's authorized responsibilities.

Where monitoring is required, staff need to understand how to record observations, communicate changes, and escalate concerns.

Records may also contain sensitive health information. Their collection, storage, access, and sharing should follow applicable Vietnamese confidentiality and personal data protection requirements.

The Law on Personal Data Protection No. 91/2025/QH15 and Decree No. 356/2025/ND-CP, both effective from January 1, 2026, provide relevant legal context.

The purpose of documentation is to support reliable decisions and continuity of care. A chart that is completed but never reviewed may create an appearance of safety without improving actual care.

Hydration Support Must Adapt When Circumstances Change

An older person's fluid needs and ability to drink may change over time.

Someone who previously managed beverages independently may develop temporary weakness after illness. A resident may need additional assistance during hot weather. Another person may experience new difficulties after a medication change or decline in mobility.

Some changes can be addressed by adjusting ordinary support arrangements. Others require clinical reassessment.

Home-based care presents particular challenges because assistance may be limited to scheduled visits.

A person may receive suitable drinking support during a morning visit but struggle to obtain beverages or access the bathroom later in the day.

If the person's functional ability declines, the original service arrangement may no longer provide adequate support. The organization, older person, and relevant supporters may need to reconsider what assistance is realistically available between visits.

Residential care facilities face different challenges. Changes in staffing, room assignments, daily routines, or residents' mobility can affect whether drinking assistance remains reliable.

A resident who previously obtained beverages independently may need more help after a fall or acute illness. Someone moving to a different care area may find that familiar routines and support arrangements have changed.

Care plans should therefore be reviewed when there are meaningful changes in health, functional ability, dependency, or service arrangements.

Relevant information about drinking support, clinical fluid instructions, swallowing requirements, and unresolved concerns should be communicated when care is transferred.

Hydration decisions also require particular sensitivity in palliative and end-of-life care.

The appropriate approach should consider comfort, the person's wishes, goals of care, swallowing ability, clinical circumstances, and the expected benefits and burdens of interventions.

Artificial hydration and other medical treatments involve separate clinical, ethical, and legal considerations. They should not be determined by routine facility drinking targets.

The objective remains individualized care rather than achieving a single numerical intake measure.

Viet Nam's Professional and Legal Framework

Viet Nam's Ministry of Health Decision No. 1976/QĐ-BYT, issued on July 1, 2026 and effective from the date of issuance, promulgates professional guidance on caring for older people at home and in the community.

The guidance covers several aspects of community-based and home-based care, including nutrition, daily activities, and practical assistance.

Section 3.1.5 addresses adequate hydration, recognizing the importance of appropriate water intake and the tendency for thirst sensation to decline with age. It also refers to adjusting water intake according to health conditions and professional advice.

The guidance provides a useful foundation for improving everyday hydration support, but its stated scope must be respected.

It should not be interpreted as imposing identical fluid requirements, monitoring frequencies, or clinical treatment procedures on every residential long-term care establishment.

The Law on Older Persons No. 39/2009/QH12, as amended, provides a broader legal foundation for respecting older people's rights, dignity, and appropriate care.

The consolidated text, Document No. 23/VBHN-VPQH, was issued on February 26, 2026.

Where hydration-related activities involve medical examination, diagnosis, clinical monitoring, or treatment, the Law on Medical Examination and Treatment No. 15/2023/QH15, as amended, and relevant professional and licensing requirements must also be considered.

Care providers should distinguish between ordinary personal assistance with drinking, observation and communication, and regulated clinical activities requiring appropriate qualifications and authorization.

The fact that a person receives care in a private home or residential establishment does not automatically make every health-related activity an ordinary caregiving task.

Similarly, guidance intended to improve home and community care should not be interpreted as creating unrestricted authority for non-clinical workers to perform medical procedures.

The organization's legal classification, authorized service scope, workforce competence, and contractual arrangements all affect its responsibilities.

For HLVN, the appropriate approach is to encourage evidence-informed, proportionate, and person-centered hydration support while avoiding unsupported claims about professional authority or mandatory clinical practices.

What International Guidance Can Contribute

International guidance offers useful reference points for improving hydration support across different care settings.

ESPEN's 2022 practical guideline provides evidence-based recommendations concerning nutrition and hydration in older people, including the prevention and recognition of low-intake dehydration, individualized drinking support, and appropriate clinical assessment.

Its 2024 guideline on nutrition and hydration in dementia adds further considerations for people living with cognitive impairment, emphasizing practical assistance, individualized care, oral care, monitoring, and the person's overall circumstances.

The Australian Aged Care Quality and Safety Commission's June 2026 clinical alert highlights the risks of delayed recognition and the importance of reliable organizational systems for hydration support.

Australia's strengthened Aged Care Quality Standards address nutrition and hydration through clinical risk management, person-centered care, monitoring, professional competence, and timely access to appropriate healthcare.

The October 2026 UK guidance on infection prevention and control in adult social care recognizes hydration as part of fundamental daily care, alongside nutrition, oral care, personal hygiene, and mobility.

Queensland Health's residential aged care clinical pathway provides more detailed clinical guidance on dehydration assessment and management, including circumstances in which medical interventions may be required.

ISO 25557:2026, Ageing Societies — Care Quality for Older Persons at Home and in Care Facilities, provides a broader reference for person-centered care, safety, workforce competence, quality management, and service coordination.

These resources are relevant to care quality improvement, but they serve different purposes.

An international clinical guideline is not automatically a national treatment protocol. A foreign regulatory standard does not establish the same legal obligations in Viet Nam. An organizational quality standard does not independently authorize medical procedures.

Vietnamese providers should use these resources to inform locally appropriate practices while following applicable national laws, professional requirements, and individual clinical instructions.

Measuring Whether Hydration Support Is Reliable

A care organization may report that drinking water is available throughout the day or that employees regularly offer beverages. These arrangements are useful, but they do not establish whether older people receive the support they need.

A more meaningful quality review examines what happens when a person has difficulty drinking.

The organization should understand who needs assistance, whether individual preferences and clinical instructions are known to staff, and whether significant changes in intake are recognized.

It should also examine whether concerns reach the appropriate person and whether necessary actions follow.

For people with identified hydration risks, quality monitoring may consider whether agreed support is delivered consistently, whether relevant observations are recorded accurately, and whether clinically significant concerns receive timely attention.

Where structured fluid charts are clinically indicated, their completeness and practical reliability may also be reviewed.

However, documentation rates should not become an objective disconnected from the older person's actual care.

Resident and family feedback, where appropriate, can provide valuable information.

Someone may report that beverages are always available but assistance takes too long. Another may explain that avoiding drinks feels easier than repeatedly requesting help with toileting.

A person receiving home care may appreciate scheduled visits but still need additional support during the hours spent alone.

These experiences can help explain why a seemingly adequate system does not work for everyone.

Organizations may also review hydration-related incidents and near misses to identify problems with staffing, communication, monitoring, or access to clinical assessment.

Outcomes require careful interpretation.

A diagnosis of dehydration does not automatically demonstrate organizational failure, and a low reported rate of dehydration does not necessarily prove that risks are being recognized effectively.

The purpose of measurement is to determine whether foreseeable problems are identified, individualized support is delivered, and escalation arrangements function as intended.

Making Safe Hydration Part of Dependable Everyday Care

Hydration support often consists of small actions that receive little attention when they work well.

A suitable drink is within reach. Someone notices when it remains untouched. A resident who needs help receives it without repeated requests. A caregiver understands why a person has begun avoiding fluids, and an important change is communicated before the situation becomes more serious.

These actions do not necessarily require sophisticated technology. They depend on awareness, appropriate organization, individual care planning, and communication between the people involved.

For home-based care, reliability requires realistic arrangements during scheduled visits and recognition of needs that may arise when workers are not present.

For residential care, it requires consistent assistance, clear communication between shifts, and access to qualified healthcare professionals when clinical concerns develop.

Personal preferences should remain central, but they must be considered alongside safety, swallowing needs, medically prescribed fluid arrangements, and the person's functional abilities.

A reliable approach does not assume that every resident needs the same volume of drinks or that offering additional water is always the correct response.

Instead, it asks whether the person can access and consume suitable fluids, whether agreed assistance is provided, and whether changes requiring further assessment are recognized promptly.

For Viet Nam, improving these everyday arrangements offers a practical opportunity to strengthen quality across home-based and residential long-term care without creating unnecessarily complex systems.

Safe hydration support is not demonstrated by a full glass of water beside an older person. It is demonstrated by whether the person can drink appropriately, receives the assistance they need, and has access to timely professional care when concerns arise.

Individual fluid needs depend on health conditions, medical instructions, swallowing ability, functional capacity, dietary intake, environmental conditions, and other relevant factors. General fluid-intake recommendations discussed in this article should not be used as universal drinking targets or override individualized clinical advice.

Hydration support must be provided within the organization's lawful services and the worker's authorized responsibilities and competence.

Care workers should not independently diagnose dehydration, prescribe or modify fluid restrictions, change prescribed fluid consistency, administer artificial hydration, or undertake regulated medical procedures outside their lawful authority and competence.

Reduced fluid intake, suspected dehydration, swallowing difficulties, significant fluid losses, and changes in health require an appropriate response based on individual circumstances and advice from qualified healthcare professionals. Serious or potentially life-threatening deterioration requires urgent medical assistance.

The presence or absence of individual symptoms such as dry mouth, dark urine, reduced skin elasticity, or dizziness should not be used alone to diagnose or exclude dehydration in older people.

Decisions involving hydration during palliative or end-of-life care must reflect individualized goals of care, informed choices, clinical circumstances, and applicable professional and legal requirements.

The Ministry of Health's Decision No. 1976/QĐ-BYT provides professional guidance concerning care for older people at home and in the community. It should not be interpreted as imposing identical clinical hydration targets or procedures on every residential long-term care provider.
