An older man recovering from a stroke begins coughing whenever he drinks water. His family notices that meals take much longer than before, but they assume he simply needs more time to recover. At home, an older woman living with dementia sometimes holds food in her mouth without swallowing. Her daughter starts giving her thinner porridge, believing it will be easier to eat, but she is unsure whether the change is safe. In a residential care facility, a resident who previously required assistance with swallowing is transferred to hospital with a respiratory infection. When she returns, the care team receives a discharge medication list but no clear instructions about what she can safely eat or drink.
These situations illustrate how swallowing difficulties can become a patient-safety concern long before a serious complication is recognized. Eating and drinking are ordinary activities, yet they require complex coordination between the mouth, throat, airway and nervous system. When that coordination is impaired, food, fluids, saliva or medication may not move safely through the swallowing process.
Swallowing difficulties, commonly described as dysphagia, can interfere with nutrition, hydration and medication administration. They may increase the risk of choking, aspiration and respiratory complications. They can also affect confidence, enjoyment of meals, social participation and the willingness to eat or drink. For some older people, the fear of coughing or choking becomes almost as disruptive as the swallowing problem itself.
The consequences are not determined by age alone. Some people develop temporary swallowing difficulties after stroke or acute illness and improve with appropriate treatment and rehabilitation. Others live with progressive neurological conditions, advanced dementia or persistent swallowing impairment that requires longer-term support.
For Viet Nam, swallowing safety is particularly relevant because older people receive care across hospitals, rehabilitation services, homes, communities and residential long-term care settings, often involving different professionals and family caregivers. A person may undergo swallowing assessment in hospital but return home to relatives who have never been shown how to prepare the recommended meals. Another may continue following dietary restrictions that are no longer appropriate because swallowing function has improved or deteriorated.
The challenge is therefore not simply to identify dysphagia or prevent coughing during meals. It is to establish a reliable process through which swallowing problems are recognized, assessed, managed, monitored and communicated as the person's condition and care setting change.
A practical Swallowing Safety Pathway should connect seven activities: early recognition, appropriate screening, professional assessment, individualized eating and drinking decisions, caregiver education, monitoring and reassessment, and communication across care settings.
The objective is not to promise that eating and drinking can become entirely risk-free. It is to reduce avoidable harm while supporting appropriate nutrition, hydration, medication administration, comfort and the person's ability to participate in decisions about their care.
Swallowing Difficulties Are Not All the Same
Swallowing depends on several closely coordinated processes. Food and fluids must be prepared and controlled in the mouth, moved through the throat and directed toward the esophagus while the airway is protected. Difficulties can occur at different stages, and their causes are not always the same.
Some older people have difficulty chewing or controlling food in the mouth. Others struggle to initiate swallowing, manage liquids or clear material from the throat. A person may also report that food becomes stuck after swallowing, suggesting a possible esophageal problem that requires a different clinical assessment.
Oropharyngeal dysphagia is particularly important from a swallowing-safety perspective because impaired coordination or airway protection may allow food, liquids or secretions to enter the airway.
Aspiration occurs when material passes below the vocal folds into the lower airway. It is different from laryngeal penetration, in which material enters the laryngeal vestibule but does not pass below the vocal folds. Aspiration should also be distinguished from choking caused by obstruction of the airway. Severe choking can become an immediate life-threatening emergency, while aspiration may occur without complete airway obstruction or an obvious choking episode.
Not every aspiration event leads to pneumonia. Whether aspiration results in respiratory infection depends on several factors, including the nature and quantity of aspirated material, oral bacterial burden, respiratory defenses and underlying health conditions. Likewise, not everyone with dysphagia develops aspiration pneumonia.
One important concern is silent aspiration. Some people aspirate without coughing or showing an obvious protective response, particularly when airway sensation or neurological function is impaired. The absence of coughing during a meal therefore does not guarantee that swallowing is safe.
Swallowing difficulties may be associated with stroke, Parkinson's disease, dementia, neuromuscular disorders, head and neck conditions, previous surgery or radiotherapy, and other illnesses. Reduced alertness, fatigue, sedating medications, oral pain and poorly fitting dentures can also interfere with eating and swallowing.
Although swallowing physiology may change with age, persistent difficulty, recurrent coughing, unexplained weight loss or a significant change in eating and drinking should not automatically be dismissed as normal aging.
Understanding what is happening, and why, is essential because different swallowing problems require different responses.
What Does the Vietnamese Evidence Tell Us?
Vietnamese research provides useful evidence that swallowing difficulties are clinically important among older hospital patients, although nationally representative information remains limited.
A study published in the Asia Pacific Journal of Clinical Nutrition in December 2021 examined 1,007 older inpatients across three large hospitals in northern Viet Nam. Nutritional status was assessed using the Mini Nutritional Assessment–Short Form, while swallowing difficulties were screened using the 10-item Eating Assessment Tool, commonly known as EAT-10.
The researchers found that 24.6% of participants had a positive EAT-10 screening result, using a threshold of three points or higher. Swallowing risk was also significantly associated with malnutrition or risk of malnutrition after adjustment for selected factors.
These findings support the importance of recognizing swallowing difficulties during hospital care. However, the 24.6% figure represents the proportion of participants who screened positive under the study's assessment approach. It is not the national prevalence of clinically confirmed dysphagia or aspiration among older Vietnamese people. The study's cross-sectional design also does not establish whether swallowing problems caused nutritional deterioration or whether both conditions developed through other underlying mechanisms.
An important development in local assessment research was published in the Hong Bang International University Journal of Science in September 2025. Researchers translated and conducted a preliminary validation of a Vietnamese version of EAT-10, involving 139 participants at the Head and Neck Radiotherapy–ENT–Maxillofacial Department of Ho Chi Minh City Oncology Hospital.
The Vietnamese EAT-10 demonstrated promising reliability and screening performance in the population studied. At a cutoff score of three or higher, the researchers reported sensitivity of 88% and specificity of 84% compared with fiberoptic endoscopic evaluation of swallowing. These are encouraging findings, but they should be interpreted within the study's population and methods. They do not establish equivalent screening performance among all older people, particularly those living with advanced dementia, significant communication difficulties or different neurological conditions.
More recent Vietnamese evidence comes from a study published in the Vietnam Journal of Community Medicine in 2026. Researchers at the Rehabilitation Center of Bach Mai Hospital evaluated swallowing function in 30 patients following stroke using the Mann Assessment of Swallowing Ability, or MASA. The study reported improvement in average MASA scores between initial assessment and discharge following swallowing rehabilitation.
This study provides useful observations about clinical swallowing rehabilitation in Viet Nam. Nevertheless, the small sample, convenience recruitment and before-and-after design without a concurrent control group limit conclusions about the independent effectiveness of the interventions used. Improvement during the study period cannot be attributed solely to rehabilitation without considering spontaneous recovery and other clinical factors.
Taken together, these studies suggest that swallowing problems deserve greater attention in hospital and rehabilitation care. They also demonstrate growing Vietnamese experience with swallowing screening and assessment.
However, they do not establish how consistently swallowing problems are identified and managed across the country's healthcare system. Evidence remains limited regarding routine practice in home care, community services, residential long-term care and transitions between settings.
The practical question for Viet Nam is therefore not only how often dysphagia occurs. It is whether older people with swallowing problems can obtain appropriate assessment and receive care that remains safe and consistent after they leave a specialist service.
Early Recognition Should Lead to Appropriate Clinical Action
Swallowing difficulties are often first noticed by the older person, a family member, a nurse or someone helping with meals.
Some warning signs are relatively obvious. The person may cough, choke or repeatedly clear their throat while eating or drinking. Their voice may sound wet or gurgly after swallowing. They may report that food is difficult to move through the throat or that swallowing requires more effort than before.
Other signs are less specific. Meals may take longer, food may remain in the mouth, or the person may need repeated swallows to clear one mouthful. They may avoid certain foods, drink less than usual, become unusually tired during meals or begin losing weight.
In people living with dementia, swallowing problems may be difficult to recognize because the person cannot reliably describe what is happening. A caregiver may instead notice food being held in the mouth, difficulty coordinating eating movements, reduced interest in meals or distress when assistance is offered.
Changes in respiratory health can also prompt assessment. Recurrent respiratory infections, coughing associated with meals or unexplained respiratory deterioration may indicate the need to consider swallowing function, although these findings are not specific to aspiration and require broader clinical evaluation.
It is useful to establish when and how symptoms occur. Does the problem involve thin liquids, solid foods, tablets or several consistencies? Is swallowing more difficult when the person is tired or drowsy? Did the problem appear suddenly after a neurological event, or has it developed gradually over several months?
These observations can help determine the urgency and direction of further assessment.
Sudden choking accompanied by an inability to breathe, speak effectively or maintain the airway requires immediate emergency action. Caregivers and staff should activate emergency assistance and follow current, appropriately taught first-aid procedures for airway obstruction. They should not continue offering food or drink during a potentially life-threatening choking episode.
Other symptoms, including newly developing dysphagia, recurrent choking, painful swallowing, significant weight loss or progressively worsening difficulty with food passage, require timely clinical evaluation. Sudden swallowing difficulties accompanied by other acute neurological symptoms should prompt urgent assessment for stroke or another serious condition.
The purpose of recognition is not to turn family caregivers into swallowing specialists. It is to ensure that clinically important changes lead to appropriate assessment rather than being dismissed or managed through unplanned dietary adjustments.
Screening Is the Beginning of Assessment, Not a Diagnosis
Swallowing screening can help identify people who may require further evaluation. However, screening and diagnosis serve different purposes.
EAT-10 is a patient-reported questionnaire that provides structured information about swallowing symptoms. A positive result suggests that further assessment may be appropriate. A negative result does not exclude every clinically important swallowing problem, particularly when the person cannot describe symptoms reliably or experiences silent aspiration.
This limitation matters for people living with advanced dementia, severe communication impairment, reduced consciousness or certain acute neurological conditions.
In hospitals, trained healthcare professionals may use structured bedside swallowing screens according to the clinical condition and local protocol. Screening can help determine whether oral intake may proceed, whether additional precautions are needed or whether a more detailed assessment should be arranged.
The American Heart Association and American Stroke Association's 2026 guideline for the early management of acute ischemic stroke recommends bedside dysphagia screening before initiating liquid or food intake in patients with acute ischemic stroke. The guideline also recognizes that screening may be performed by speech-language pathologists or other appropriately trained healthcare professionals.
For patients who fail or cannot participate in bedside screening because of neurological impairment, the guideline considers instrumental swallowing assessment reasonable when it can help establish the severity of dysphagia and aspiration risk.
These recommendations are clinically important but apply specifically to acute ischemic stroke. They should not be interpreted as requiring every older person in every care setting to undergo the same screening or instrumental assessment.
A practical swallowing-safety pathway should distinguish between patients requiring condition-specific screening, those with symptoms that warrant targeted assessment and those whose existing swallowing plans require reassessment because their condition has changed.
When swallowing safety is uncertain, decisions about oral intake should follow an appropriate clinical protocol. Temporary restriction of oral intake may be necessary in selected situations, but it should not become an indefinite default without reassessment and arrangements for nutrition, hydration and medication administration.
The 2026 stroke guideline also acknowledges an important limitation: swallowing screening, instrumental assessment and restrictions on oral intake cannot prevent every aspiration event or case of hospital-acquired pneumonia.
Screening should therefore lead to appropriate clinical action, not create a false sense of safety because a test has been completed.
Professional Assessment Should Explain the Swallowing Problem
Once a clinically important swallowing difficulty is suspected, further assessment should reflect the person's symptoms, underlying conditions and care needs.
Clinical swallowing evaluation may consider neurological function, alertness, respiratory status, oral structures, chewing ability, secretion management and the person's experience of swallowing. Depending on the setting and relevant professional competencies, assessment may include observation of swallowing and selected oral intake trials when these can be undertaken safely.
The objective is not merely to determine whether someone passes or fails a bedside test. It is to understand which swallowing processes are affected, what risks may be present and which management options are appropriate.
Some people can be managed initially using clinical assessment findings. Others require instrumental evaluation, particularly when silent aspiration is suspected, symptoms remain unexplained or important treatment decisions depend on a more detailed understanding of swallowing physiology.
Two established methods are videofluoroscopic swallow study, commonly called VFSS, and flexible endoscopic evaluation of swallowing, or FEES.
VFSS uses dynamic radiographic imaging to examine swallowing with selected food and fluid consistencies. It can provide information about oral and pharyngeal movement, airway protection and relevant swallowing mechanisms.
FEES uses a flexible endoscope to visualize pharyngeal and laryngeal structures during swallowing assessment. It can provide information about secretion management, residue and airway invasion, although some phases of swallowing are temporarily obscured during the endoscopic whiteout.
These investigations have different strengths and limitations. Neither is automatically the best choice for every patient. Selection depends on the clinical question, the person's condition, available expertise, feasibility and how the findings are expected to influence management.
For example, bedside FEES may be useful for a patient who cannot easily be transported to a radiology department. VFSS may be preferable when detailed visualization of swallowing movement or particular physiological questions is required.
Assessment must also distinguish oropharyngeal dysphagia from possible esophageal disorders. Progressive difficulty swallowing, painful swallowing or the sensation that food becomes stuck after passage through the throat may require gastroenterological or other specialist evaluation rather than food texture modification alone.
In Viet Nam, access to swallowing assessment expertise and equipment may vary between hospitals and regions. Organizations that cannot provide specialized investigations should still be able to recognize when referral is needed, establish appropriate interim care arrangements and identify a feasible pathway for further evaluation.
The value of assessment lies in producing a clinically meaningful management plan, not simply obtaining another test result.
Safer Eating and Drinking Requires Individualized Decisions
Once swallowing difficulties have been assessed, one of the most important decisions concerns what the older person can eat or drink, under which conditions and with what assistance.
Some individuals can continue their usual diet with appropriate positioning, pacing or supervision. Others may benefit from changes to food texture or drink thickness. Selected patients may require swallowing rehabilitation, temporary clinically assisted nutrition or more complex decisions about how their nutritional needs should be met.
The International Dysphagia Diet Standardisation Initiative, or IDDSI, provides a framework for describing food textures and drink thicknesses using standardized terminology. It consists of eight numbered levels, from 0 to 7. Drink levels range from 0 to 4, while food levels range from 3 to 7, with levels 3 and 4 covering both foods and drinks.
This framework can improve communication between clinicians, hospital kitchens, rehabilitation providers, care workers and families, particularly when patients move between services.
However, IDDSI is a terminology and testing framework, not an independent treatment protocol. It does not determine which level is suitable for a particular person. Recommendations must follow individualized clinical assessment, and foods or drinks should be prepared and checked under relevant serving conditions.
A particularly important concern is the assumption that thicker liquids are always safer.
A systematic review and meta-analysis published in the Journal of Oral Rehabilitation in 2025 examined thickened liquids in adults with neurogenic dysphagia. The findings suggested improvements in several instrumental measures of swallowing safety, including reduced observed aspiration events. However, the evidence was limited by differences between studies, the inclusion of nonrandomized research and uncertainty about longer-term clinical outcomes. Thickened liquids were also associated with increased oral and pharyngeal residue.
Reducing aspiration observed during a swallowing assessment does not automatically establish that a treatment reduces pneumonia, hospitalization or mortality.
A separate systematic review published in the American Journal of Speech-Language Pathology in 2023 identified potential adverse events and effects associated with thickened-liquid use. These included dehydration concerns, reduced intake, lower quality of life and medication-related difficulties, although the strength and consistency of evidence varied.
The Royal College of Speech and Language Therapists' 2024 position paper similarly emphasizes that thickened fluids should not be prescribed without a detailed drinking and swallowing assessment by an appropriately trained practitioner. Decisions should consider the person's preferences, expected benefits, potential treatment burdens and the need for ongoing review.
These findings do not mean that thickened liquids should never be used. They mean that expected benefits must be weighed against possible harms and that treatment requires appropriate monitoring.
Food texture modification deserves similar care. Pureed, minced or softened foods may help selected individuals, but they are not universally appropriate. Overly restrictive, unappealing or inconsistently prepared meals may reduce intake and enjoyment without delivering the intended safety benefit.
This is particularly relevant in Viet Nam, where common meals include rice, vegetables, fish, meat, soups, porridge and noodles. Some dishes combine solids and thin liquids or contain different textures within the same serving.
A bowl of porridge should not automatically be considered safe simply because it is soft. Its consistency, the presence of separate liquid, particle size and the person's swallowing physiology may all be relevant. Similarly, a soup or noodle dish may require individualized preparation rather than being universally classified as suitable or unsuitable.
A workable plan should translate professional recommendations into familiar foods that are available and practical for the older person or caregiver to prepare.
The decision should also consider food preferences, nutritional adequacy, hydration, cultural habits and the consequences of restrictions on quality of life.
A swallowing plan is not successful simply because the prescribed food consistency can be achieved. It must also be acceptable, nutritionally appropriate and feasible to maintain.
Safe Mealtime Support Depends on Everyday Practice
Even a well-designed swallowing plan can fail if it is not understood and followed during ordinary meals.
Someone may receive appropriate recommendations in hospital but continue to struggle at home because caregivers prepare food differently, provide assistance too quickly or do not recognize when the person's condition has changed.
Mealtime support should begin with an assessment of the person's condition at that moment. Someone who is unusually drowsy, acutely unwell or unable to maintain an appropriate eating position may need clinical review before oral intake continues.
Stable seating and suitable positioning can be important. Many people benefit from an upright position, but specific requirements depend on their physical condition and swallowing abilities. Patients with reduced trunk control or neurological impairment may require individualized postural support.
The amount and pace of food or drink should reflect the person's assessment and care plan. Assistance should allow enough time for chewing, swallowing and clearing the mouth without rushing the person through the meal.
Caregivers should not continue feeding when the person repeatedly coughs, becomes distressed, develops breathing difficulties or shows other significant warning signs. The appropriate response may involve stopping the meal, obtaining clinical advice or activating emergency assistance according to the situation.
Specialized techniques, including particular swallowing maneuvers, exercises or postural adjustments, should only be used when recommended by appropriately trained professionals. A technique that benefits one patient may be ineffective or inappropriate for another.
Practical adaptations can also improve participation. Appropriate utensils, comfortable seating, reduced distractions and simple verbal prompts may help some older people remain involved in eating rather than becoming entirely dependent on others.
The social experience of meals matters. Eating is part of family life, culture and enjoyment, not simply a means of delivering calories and fluids. A person who requires assistance should still have opportunities to express preferences, participate in mealtimes and maintain familiar routines wherever possible.
Good mealtime support combines clinical safety with comfort, dignity and the person's remaining abilities.
Oral Hygiene and Swallowing Safety Are Connected, but Not Interchangeable
Aspiration pneumonia involves more than the movement of food or liquid into the airway.
The bacterial burden of oral secretions, respiratory defenses, mobility and underlying health conditions may influence whether aspiration leads to infection. This helps explain why aspiration pneumonia cannot be prevented solely by modifying food texture or restricting oral intake.
Oral secretions may still be aspirated when someone is not eating or drinking. Tube feeding also does not eliminate the risk of aspiration.
The 2026 AHA/ASA acute ischemic stroke guideline recognizes that an oral hygiene protocol may be reasonable to reduce pneumonia risk, based largely on observational evidence. However, uncertainty remains about which specific oral hygiene methods are most effective.
Appropriate mouth care should therefore remain part of everyday support for older people with dysphagia. This may involve cleaning teeth, dentures and oral tissues, recognizing oral discomfort and ensuring that people unable to perform mouth care independently receive suitable assistance.
The approach should reflect the person's condition, level of dependence and swallowing or aspiration risks. Some caregivers may require additional instruction when providing mouth care to people with significant impairment.
Oral hygiene complements swallowing assessment and management. It does not replace them, and it should not be presented as a guarantee against aspiration pneumonia.
Swallowing Rehabilitation Requires Appropriate Selection and Reassessment
Swallowing ability can change substantially over time.
After stroke, some people recover swallowing function during rehabilitation. Others continue to have persistent difficulties. In progressive neurological conditions, swallowing may deteriorate gradually or fluctuate with fatigue, medication effects and overall health.
Rehabilitation should therefore be based on the underlying impairment, realistic treatment goals and the person's ability to participate.
Specialized interventions may include exercises, compensatory strategies, behavioral techniques or other treatments selected according to clinical findings. Their effectiveness varies, and not every intervention is appropriate for every type of dysphagia.
The 2026 AHA/ASA stroke guideline includes recommendations concerning pharyngeal electrical stimulation for selected patients with post-stroke dysphagia. It states that this treatment may be reasonable in non-tracheostomized patients with stroke and dysphagia to improve swallowing function. In selected patients with severe stroke who have required tracheostomy and mechanical ventilation, treatment after ventilator weaning is considered reasonable to facilitate readiness for decannulation.
These recommendations reflect developments in specialized stroke care. They should not be interpreted as routine treatment for every older person with dysphagia, or as establishing that the intervention is available or approved for all relevant indications in Viet Nam.
For most care organizations, an equally important issue is ensuring that treatment plans remain responsive to changing swallowing function.
A person who required modified food immediately after stroke may later tolerate a less restrictive diet following reassessment. Continuing unnecessary restrictions can reduce food choice and may affect intake or quality of life.
Conversely, a person living with a progressive condition may require additional assistance or changes to their eating and drinking plan as swallowing becomes more difficult.
Reassessment may also be appropriate after acute respiratory illness, hospitalization, surgery, changes in alertness or clinically important deterioration.
The timing should reflect the person's condition and level of risk rather than a rigid universal schedule.
A swallowing recommendation should be treated as a current clinical decision that may need review, not a permanent label attached to the person.
Caregiver Education Should Make the Plan Work at Home
For many older people in Viet Nam, the people responsible for preparing meals and providing eating assistance are family members rather than swallowing specialists.
This creates a practical challenge. A clinician may recommend a particular diet or feeding technique, but the plan can become ineffective if the family does not understand what the recommendation means.
Caregiver education should therefore be a routine part of swallowing management rather than an optional activity at discharge.
Instructions need to explain what the person can currently eat and drink, how food should be prepared, what assistance is required and which warning signs should prompt further assessment. When texture-modified foods or thickened drinks are recommended, demonstrations using familiar Vietnamese foods may be more useful than technical terminology alone.
Understanding should be checked through discussion or demonstration. A caregiver who can describe the instructions may still need support in preparing the recommended food consistency or positioning the person appropriately.
Caregivers should also know when not to continue feeding and how to seek medical assistance. Repeated coughing or choking, respiratory symptoms, significant changes in alertness and worsening swallowing difficulty should not simply be managed by making food softer or drinks thicker without professional review.
Medication administration requires particular attention. Some people with dysphagia have difficulty swallowing tablets, but crushing tablets or opening capsules is not automatically safe. Certain formulations must not be altered, while mixing medicines with food or thickened liquids may affect administration or drug performance. The prescriber or pharmacist should be involved when an alternative formulation or method is needed.
Family members should not be expected to diagnose dysphagia, perform specialist assessment or independently change clinically prescribed swallowing management.
Professional responsibilities should also be clear. Frontline workers may be trained to recognize symptoms, assist with meals and monitor defined concerns, while clinical decisions and specialist interventions require appropriate qualifications and competencies.
Because professional training and regulatory scopes differ across countries, international roles such as speech-language pathologist should not automatically be assumed to have identical legal status or responsibilities in Viet Nam.
The practical objective is to ensure that everyone involved understands what they are expected to do, what they must not do independently and when additional professional assessment is necessary.
A Swallowing Plan Must Be Monitored, Not Merely Documented
Swallowing care should not end when a diet recommendation has been written.
The person may initially tolerate a particular food consistency but later experience fatigue, declining intake or worsening respiratory symptoms. Another may improve and no longer require some of the original restrictions.
Monitoring should therefore consider whether the person can follow the plan, receives sufficient food and fluids, tolerates the recommended consistencies and experiences any new difficulties.
Relevant observations may include coughing or choking, oral residue, mealtime duration, food and fluid intake, weight changes, hydration concerns, respiratory symptoms and the person's experience of eating.
These findings must be interpreted carefully. Absence of coughing does not exclude silent aspiration, while pneumonia does not necessarily prove that a specific swallowing intervention failed.
The older person's preferences and experience also matter. Are meals frightening or exhausting? Can they still enjoy familiar foods? Is the recommended diet acceptable? Does the caregiver have the resources and skills to prepare it consistently?
A plan that appears to reduce aspiration during testing but results in inadequate intake or substantial distress may require reassessment.
Monitoring should connect observations with clinical decisions. Changes need to be reported to the appropriate professional, reviewed and followed by a revised plan when indicated.
The aim is not simply to count incidents. It is to understand whether swallowing care continues to meet the person's clinical and everyday needs.
Care Transitions Must Communicate More Than a Diet Label
Swallowing management can become fragmented when an older person moves between hospitals, rehabilitation services, homes and residential care facilities.
A patient may receive a detailed swallowing assessment during hospitalization, but the discharge summary may contain only a brief instruction such as "soft diet" or "thickened liquids." Different caregivers may interpret those terms differently.
One facility may prepare finely minced food, while another serves larger soft pieces. A family member may add water to porridge because it appears easier to swallow, without understanding why a particular consistency was recommended.
These differences can create risks even when everyone involved believes they are following the instructions.
A safer transition should communicate the swallowing problem, relevant assessment findings, current food and fluid recommendations, assistance requirements, medication considerations and warning signs that require further review.
When IDDSI terminology is used, the recommended levels should be clearly documented and accompanied by practical preparation instructions. Examples based on familiar foods may be particularly helpful for family caregivers.
The plan should also identify whether nutrition and hydration require additional monitoring, whether swallowing rehabilitation is ongoing and who is responsible for reassessment.
Communication with those preparing meals is important, but sensitive clinical information should be shared only as necessary and in accordance with applicable privacy and confidentiality requirements.
For the receiving team, knowing the current diet is not enough. They need to understand why it was selected, how it should be implemented and what to do if the person's condition changes.
A successful handover means that the next caregiver can provide appropriate support without having to reconstruct the entire swallowing history or guess the meaning of a brief instruction.
Dementia, Palliative Care and Eating With Acknowledged Risks
Swallowing difficulties become particularly complex when an older person lives with advanced dementia or has a serious illness requiring palliative care.
Eating and drinking carry meanings that extend beyond nutrition. Meals can provide comfort, familiarity, enjoyment and connection with family. Losing the ability to eat normally may therefore be distressing for the person and those providing care.
In dementia, eating difficulties may involve more than swallowing physiology. The person may no longer recognize food, forget how to use utensils, become distracted, hold food in the mouth or require increasing assistance.
These changes should prompt assessment of potentially reversible contributors, including acute illness, oral discomfort, medication effects, poor positioning and unsuitable mealtime conditions. Appropriate support may involve simplifying the environment, allowing more time, offering familiar foods and providing assistance that matches the person's abilities.
The ESPEN guideline on nutrition and hydration in dementia, updated in 2024, emphasizes individualized nutritional assessment, suitable mealtime support, prevention of malnutrition and dehydration, and appropriate staffing and care practices.
The guideline also distinguishes between different stages of dementia when considering clinically assisted nutrition.
Temporary enteral nutrition may be appropriate for selected people with mild or moderate dementia when substantially reduced intake is mainly caused by a potentially reversible condition. However, the guideline recommends against initiating enteral nutrition in severe dementia. It also recommends against initiating enteral or parenteral nutrition and parenteral hydration during the terminal phase of life.
These recommendations reflect an important clinical and ethical distinction. An older person with a potentially reversible neurological problem may benefit from temporary nutritional support while recovery is expected. Someone with advanced progressive dementia and irreversible eating difficulties may face a different balance of benefits and burdens.
A Cochrane review published in 2021 examined enteral tube feeding among people with severe dementia. It found no convincing evidence that gastrostomy feeding improved survival and identified an increased risk of pressure ulcers associated with gastrostomy feeding. The evidence for many other outcomes was uncertain, and none of the included studies directly assessed quality of life.
These limitations matter. They do not justify making categorical claims about every individual outcome or assuming that all forms of tube feeding have identical effects.
The American Geriatrics Society's position statement on feeding tubes in advanced dementia supports careful hand feeding rather than routine tube placement when eating difficulties arise, with attention to the person's comfort and preferences.
Tube feeding also does not eliminate aspiration risk. Oral secretions or refluxed material may still be aspirated, and feeding tubes can introduce their own complications.
Decisions should therefore consider the underlying condition, likelihood of recovery, expected benefits, treatment burdens, the person's wishes and the goals of care. Recommendations developed for severe dementia should not be generalized to every older person with dysphagia.
Eating and Drinking With Acknowledged Risks
Some people may continue oral eating and drinking despite a recognized risk of aspiration, choking, malnutrition or dehydration.
The Royal College of Speech and Language Therapists uses the term eating and drinking with acknowledged risks to describe decisions of this kind. Its multidisciplinary guidance emphasizes clinical assessment, shared decision-making, documentation, communication and review.
This approach does not mean ignoring swallowing risk or allowing unrestricted feeding without assessment. It recognizes that the balance between safety, comfort, enjoyment and treatment burden differs according to the person's condition and goals.
For someone approaching the end of life, being able to enjoy small amounts of familiar food or drink may be more meaningful than pursuing increasingly restrictive interventions of uncertain benefit.
A thoughtful plan should establish what the person hopes to achieve, which risks are understood, which practical measures may reduce avoidable harm and what should happen if symptoms or circumstances change.
Depending on the situation, this may involve assisted oral intake, selected preferred foods, appropriate positioning, careful pacing, mouth care and agreed responses to choking, respiratory deterioration or other clinical changes.
The decision should follow appropriate assessment and discussion with the person and, where relevant, those lawfully involved in healthcare decisions.
When decision-making ability is impaired, applicable Vietnamese requirements concerning consent, representation and professional responsibilities must guide the process. International guidance on mental capacity or surrogate decision-making should not be treated as automatically establishing the same legal arrangements in Viet Nam. Dementia as a diagnosis should not, by itself, be treated as proof that a person is unable to participate in decisions.
The ESPEN practical guideline on ethical aspects of medical nutrition therapy, published in 2026, reinforces the importance of a clear clinical indication, achievable treatment goals, appropriate consent and the consideration of benefits and burdens. This is a consensus-based ethical guideline rather than new evidence from clinical trials, and its principles must be applied within the relevant legal and clinical context.
For Viet Nam, these discussions are particularly important because families often play an active role in feeding and care decisions. Family participation can provide valuable knowledge about the older person's preferences and circumstances, but it should not automatically replace the person's own wishes and rights.
The objective is neither to promise completely risk-free eating nor to withdraw oral intake automatically whenever dysphagia is identified.
It is to reach a clinically informed, proportionate and person-centered decision that respects safety, comfort, nutrition, hydration and quality of life, with clear responsibilities for implementation and review.
Viet Nam's 2026 Guidance Provides a Foundation for Everyday Swallowing Support
Swallowing-related care is addressed in Viet Nam's current professional guidance on caring for older people at home and in the community.
Ministry of Health Decision No. 1976/QĐ-BYT, issued on 1 July 2026, provides professional guidance across several areas of physical health, daily functioning, nutrition and personal assistance.
The guidance recognizes that food preparation should reflect an older person's chewing, swallowing and digestive abilities. It discusses selecting suitable preparation methods and adjusting food consistency when swallowing difficulties are present, as well as monitoring nutritional status and changes in eating ability.
Chapter IV includes practical guidance on supporting older people with eating and drinking. It addresses appropriate preparation, positioning, communication, observation during meals and the recognition of difficulties such as food retention, choking and related symptoms.
These provisions are relevant because swallowing problems may first be noticed during ordinary meals at home rather than in a specialist clinical service. They also support the importance of explaining care activities, obtaining agreement and observing how the older person responds to assistance.
However, Decision 1976 should not be described as a comprehensive national clinical practice guideline for diagnosing or treating oropharyngeal dysphagia. It does not establish a national protocol for FEES or VFSS, standardized clinical prescription of IDDSI levels or specialist swallowing rehabilitation across all healthcare settings.
Its everyday care instructions should therefore be understood within their intended scope. They are not a substitute for individualized clinical assessment, particularly when aspiration risk or a complex swallowing disorder is suspected. Recommendations concerning recognition or first aid should also be applied with appropriate training and reference to current emergency-care protocols.
Circular No. 34/2026/TT-BYT, issued on 8 September 2026, provides additional implementation context for relevant activities under the National Target Programme on Health Care, Population and Development for 2026–2035, Phase I: 2026–2030. It refers to Decision 1976 for professional guidance in applicable community-based older-person care activities.
This creates opportunities to improve caregiver knowledge and practical support. It does not establish a separate mandatory nationwide clinical dysphagia-management program.
The Law on Medical Examination and Treatment No. 15/2023/QH15, effective from 1 January 2024, also provides a relevant framework for patient rights, information, consent and professional responsibilities within its scope. Provisions concerning patients' rights to participate in or refuse treatment and the exercise of rights when a patient has legally recognized difficulties with decision-making require particular attention in complex clinical situations.
These considerations are especially important when clinical decisions involve swallowing assessment, restrictions on oral intake or medically assisted nutrition. Decisions should follow applicable Vietnamese law rather than assume that family members automatically hold the same legal authority described in guidance from other countries.
International recommendations from AHA/ASA, ESPEN, IDDSI and RCSLT provide valuable professional references, but they do not automatically become binding Vietnamese legal requirements or accreditation standards.
The responsibilities of each service depend on its activities, licensing status, available professional competencies and applicable Vietnamese regulations.
The practical opportunity is to connect guidance on everyday care with evidence-informed clinical assessment, individualized management, caregiver education and communication between services.
Building a Practical Swallowing Safety Pathway Across Care Settings
A Swallowing Safety Pathway does not have to be a separate specialist program in every organization. It can be developed as a practical care process that connects existing clinical and caregiving responsibilities, with arrangements for additional assessment and referral when necessary.
For Healthy Longevity Vietnam, the proposed pathway can be organized around seven connected activities: recognition, screening, professional assessment, individualized management, caregiver support, monitoring and reassessment, and communication across settings.
Recognition should ensure that clinically important symptoms are noticed and acted upon. Staff and caregivers need to understand common warning signs and know when emergency assistance or timely clinical evaluation is necessary.
Screening should help identify people who require further evaluation, using tools and protocols suited to the clinical population. A positive result should lead to an appropriate next step rather than remain in the record without follow-up.
Professional assessment should clarify the swallowing problem, identify clinically relevant risks and guide management. The pathway should establish who can undertake clinical swallowing evaluation, when instrumental testing is appropriate and how referrals can be arranged.
Individualized management should establish suitable eating and drinking recommendations, assistance needs, medication considerations and any rehabilitation or alternative nutrition arrangements. The plan should reflect clinical findings, possible benefits and harms, and the person's preferences and goals.
Caregiver support should make the recommendations workable during ordinary meals. Instructions need to be understandable, practical and appropriate to the foods, equipment and assistance available. Training should include opportunities to verify that caregivers can apply the plan correctly.
Monitoring and reassessment should determine whether the plan continues to support safe intake, nutritional and hydration needs, comfort and participation. Changes in health or swallowing function should prompt review rather than indefinite continuation of outdated restrictions.
Communication across care settings should ensure that relevant assessment findings, current recommendations, assistance needs and follow-up responsibilities accompany the person whenever care is transferred.
These activities are interdependent. Screening without appropriate assessment may fail to clarify the problem. Assessment without caregiver education may not change everyday practice. A hospital plan may become ineffective after discharge if relatives cannot reproduce the recommended food consistency or do not know when to seek reassessment.
The pathway must also reflect the resources and competencies of the service. A large hospital may have access to specialist swallowing teams and instrumental testing. A smaller hospital, community provider or residential care facility may rely more heavily on early recognition, clearly defined interim measures and referral arrangements.
Not every organization needs to provide the same procedures, but each should know which responsibilities it can safely fulfill and when additional professional support is required.
This proposed pathway is a practical quality-improvement approach informed by existing guidance. It should not be confused with a separately validated international framework or a mandatory Vietnamese clinical standard. Its value should ultimately be assessed through implementation, feasibility and meaningful patient outcomes.
Measuring Swallowing Safety Means Looking Beyond Aspiration Events
Healthcare organizations may record whether a patient has dysphagia, receives a modified diet or develops pneumonia. These data can be useful, but they do not necessarily show whether swallowing care is working well.
A more meaningful approach should examine whether relevant patients are identified, receive appropriate assessment and have a management plan that can be implemented consistently.
Potential process measures include completion of indicated swallowing screening, timely referral after concerning results, documentation of food and fluid recommendations, caregiver education and reassessment following clinically important changes.
Care transitions deserve particular attention. Organizations may review whether patients leave hospital with clear instructions, whether medication administration has been considered and whether receiving caregivers understand the plan.
Outcomes should also extend beyond choking or respiratory infection. Food and fluid intake, weight changes, hydration concerns, meal-related distress, difficulty tolerating the recommended diet and the person's own experience of eating may all be relevant.
Incidents such as choking, suspected aspiration-related deterioration or inappropriate food delivery should be reviewed when they occur. However, their interpretation requires clinical context. Aspiration pneumonia has multiple contributing factors, and its occurrence cannot always be attributed to one failure in care. Conversely, a low recorded number of choking episodes does not establish safe swallowing when silent aspiration or inadequate intake may be present.
For someone undergoing rehabilitation, improvement in swallowing function and a safe return to less restrictive eating may be important outcomes. For a person receiving palliative care, comfort, enjoyment and consistency with goals of care may appropriately have greater weight.
These are potential measures for local quality improvement, not a nationally mandated Vietnamese swallowing-safety indicator set.
The purpose is to understand whether the pathway helps older people receive appropriate care and whether problems are recognized and addressed as circumstances change.
From Swallowing Assessment to Safer, More Meaningful Meals
For an older person recovering from stroke, good swallowing care may mean gradually returning to familiar foods while reducing avoidable risk. For someone living with Parkinson's disease, it may mean receiving assessment and support that make meals less difficult and exhausting. For a person with advanced dementia, it may mean being helped to enjoy food and drink in a way that is consistent with comfort and goals of care.
For families, good care means understanding swallowing difficulties, knowing which precautions are appropriate and receiving clear guidance without being expected to make complex clinical decisions alone.
For hospitals and rehabilitation services, it means ensuring that screening and assessment lead to appropriate management and that restrictions are reviewed as swallowing function changes. For home and community care, it means making recommendations understandable and feasible. For residential long-term care, it means maintaining consistent support across staff, shifts and changing care needs.
As Viet Nam develops more age-friendly, integrated and long-term care, swallowing safety deserves recognition as part of routine healthcare quality and patient-safety practice.
A safe swallowing pathway should not end with a test result, a dietary label or a discharge instruction. It should connect clinical assessment with the circumstances in which an older person actually eats and drinks.
The most meaningful question is not simply whether someone coughed during a meal or passed a swallowing screen. It is whether their swallowing needs were recognized, appropriately assessed and managed, whether caregivers understood the plan, and whether the person could receive suitable nutrition, hydration and medication while maintaining comfort, dignity and participation in everyday life.
High-quality swallowing care is not about eliminating every possible risk through restriction. It is about making informed, proportionate and person-centered decisions that reduce avoidable harm while preserving the meaning and enjoyment of eating and drinking.
That is why a reliable Swallowing Safety Pathway belongs within safe, age-friendly and coordinated care for older people across every care setting.
