Educational draft · awaiting clinical reviewThe full textbook explains uncertainty but does not replace live national or local guidance, specialist advice, or current prescribing information.
Decide separately about assisted nutrition and hydration using clinical goals, swallowing and refeeding assessment, capacity, lawful authority and monitored benefit-versus-burden trials.
Clinically assisted nutrition includes enteral feeding through a nasogastric, gastrostomy or jejunal tube and parenteral nutrition through venous access. Clinically assisted hydration supplies fluid by enteral, intravenous or subcutaneous routes. Both are medical interventions. Supporting a person to eat and drink orally, providing mouth care and offering preferred tastes remain fundamental care and should continue whenever safe, wanted and beneficial.
The decision begins with the clinical problem. Acute stroke, delirium, painful mouth disease or a temporary swallowing deterioration may improve, making short-term nasogastric feeding or hydration a bridge to recovery. Advanced frailty or severe dementia may instead involve progressive loss of appetite and swallowing with little realistic prospect that a tube will restore function or comfort. Route choice must match the goal and probable duration rather than a reflex response to weight loss.
Capacity is decision-specific. A person with capacity decides whether to accept an offered clinically appropriate intervention after benefits, burdens and alternatives are explained. If capacity is absent, identify any valid applicable advance refusal and authorised proxy, involve the person as far as possible, consult those close to them and follow the legal framework in the relevant UK nation. The clinical team is responsible for offering treatments capable of overall benefit; neither relatives nor clinicians should frame the issue as feeding versus abandonment.
Cough, choking, wet voice, prolonged meals, pocketing, recurrent pneumonia or distress with intake should prompt skilled swallowing assessment and immediate safe-position measures.
Unintentional weight loss, low BMI, loose clothing, muscle loss, poor intake and impaired wound healing require nutritional assessment in clinical and functional context.
Thirst, dry mucosa, reduced urine, postural symptoms, delirium and rising sodium or urea may support dehydration, but signs are less specific in frailty.
Falling appetite, consciousness and swallowing within a wider irreversible last-days trajectory differs from an isolated reversible intake problem and changes the likely benefit.
Very little intake, major recent weight loss, low BMI, alcohol dependence or low phosphate, potassium or magnesium identify a need for cautious staged feeding.
Repeated tube removal, distress, restraint, line infection, diarrhoea, overload or unwanted transfers may outweigh biochemical or weight-based gains.
A person may benefit from a short hydration trial without enteral calories, or from nutrition with tightly limited fluid; assess and prescribe each separately.
Tube feeding bypasses oral transfer but does not prevent aspiration of saliva or refluxed feed, so respiratory risk never falls to zero.
Dry mouth often reflects mouth breathing, medicines and reduced saliva; cleaning, lubrication and frequent safe sips may outperform systemic fluid.
NICE advises against routine enteral feeding in severe dementia unless a potentially reversible comorbidity creates a specific, time-limited indication.
Stopping a treatment that no longer provides overall benefit is ethically approached through the same clinical and lawful reasoning used when deciding not to start.
Food expresses care, identity and relationship, so acknowledge cultural and emotional significance while explaining what medical tubes can and cannot achieve.
Eating and drinking with acknowledged risks may honour a capacitated person's priorities or a lawful person-centred plan when restrictions cause greater burden.
Calling all reduced intake starvation without distinguishing reversible dysphagia, progressive frailty and the physiology of dying.
Assuming a feeding tube prevents aspiration pneumonia or restores function in advanced irreversible dementia.
Starting full calories after prolonged poor intake without refeeding-risk assessment and electrolyte monitoring.
Giving standard hydration volumes despite heart failure, anuria, oedema or increasing respiratory secretions.
Treating family preference as legal consent while failing to establish capacity, advance decisions or proxy authority.
Using repeated restraint to maintain a tube without reviewing whether treatment burden now exceeds benefit.
Stopping mouth care, safe tastes and compassionate hand feeding after deciding against clinically assisted nutrition.
Beginning an open-ended trial with no measurable goal, review date or stopping criteria.

A care-home resident with severe dementia has progressive dysphagia and weight loss without an identified reversible illness. Which approach best reflects NICE guidance?

Potential benefits include recovery support, medicine delivery, correction of symptomatic dehydration and maintaining nutrition when the gastrointestinal tract or swallowing route is temporarily unavailable. Harms include aspiration, fluid overload, infection, tube displacement, nasal or abdominal injury, diarrhoea, metabolic disturbance, restraint, reduced social pleasure and repeated transfer. Renal, hepatic and cardiac impairment change fluid volume, electrolyte, sodium, glucose and protein planning, requiring dietetic and specialist input.
A time-limited trial is useful when benefit is uncertain. Define the goal, such as improved alertness from hydration or recovery of swallow after acute illness; record the route and review time; monitor objective and person-centred outcomes; and stop or reduce if harm outweighs benefit. In the last days, NICE advises at least 12-hourly monitoring after assisted hydration begins. Good mouth and lip care often addresses dry-mouth distress more directly than systemic fluid.
