Inpatient and outpatient eating disorder treatment differ primarily in where someone receives care, how continuously their physical and psychiatric health is monitored, how much support is available around meals and daily routines, and how quickly a clinical team can respond if safety changes. Outpatient care involves scheduled appointments while the person lives at home. Inpatient care provides 24-hour hospital-level supervision when a person cannot safely be stabilized or treated with less intensive support. Between these settings are intensive outpatient programs, partial hospitalization/day programs, and residential treatment, each with a different role.

The right setting depends on current medical stability, nutritional compromise, behavior patterns, psychiatric risk, age and development, support at home, access to skilled clinicians, and response to previous treatment. A person may need hospital care at a higher body weight, while another person with an eating disorder may be treated safely as an outpatient following comprehensive assessment. The NICE guideline explicitly advises against using a single weight or BMI threshold for admission decisions.

This guide compares what actually changes in treatment, explains when hospital admission becomes appropriate, examines clinical evidence and its limitations, and offers a practical framework for preparing for evaluations and transitions. For the full continuum and referral decision process, also see Eating Disorder Levels of Care: When Higher Support Is Needed.

What is the difference between inpatient and outpatient eating disorder treatment?

Outpatient eating disorder treatment is coordinated clinical care delivered through scheduled visits with professionals such as a primary care clinician, eating-disorder specialist, therapist, registered dietitian, and psychiatrist when indicated. The individual usually sleeps at home and participates in school, work, and family life while carrying out an agreed treatment plan between appointments. Frequency and composition vary with the diagnosis, the person's health, and the program.

Inpatient treatment means admission to a hospital or specialized unit with staff present around the clock. A medical inpatient unit can monitor heart rhythm, vital signs, blood tests, hydration, medication effects, and nutritional rehabilitation when complications require this intensity. A psychiatric or specialist eating-disorder inpatient unit may also provide a structured therapeutic environment and close psychiatric supervision; capabilities differ among facilities. A general medical ward, a specialist eating-disorder hospital unit, and a psychiatric inpatient unit have overlapping but distinct functions.

This distinction concerns treatment setting, not diagnostic status. Anorexia nervosa, atypical anorexia nervosa, bulimia nervosa, binge eating disorder, avoidant/restrictive food intake disorder (ARFID), other specified feeding or eating disorder (OSFED), and unspecified feeding or eating disorder (UFED) can require different pathways even when two people share similar symptoms. See the eating-disorders clinical overview for diagnostic definitions.

Inpatient vs outpatient: a side-by-side comparison

Where you live and the daily schedule

In outpatient care, the person returns home after appointments and practices eating, coping, and other recovery skills in the environments where difficulties occur. Appointments might be in person or, when clinically appropriate, virtual. Family members and other supporters often take a substantial role, particularly for younger patients. Treatment must account for school or work demands, travel, meals, transportation, privacy, and the realities of home.

In hospital-based inpatient care, the person stays overnight and receives a defined daily clinical schedule. Staff may provide supervised nutrition, medical evaluation, supportive nursing care, psychological interventions, psychiatric consultation, and support with distress. The routine and privileges vary by unit and risk. Staff availability is continuous even when individual psychotherapy sessions are intermittent.

Medical monitoring and immediate response

Outpatient monitoring can include repeat examinations, orthostatic vital signs, laboratory tests, and electrocardiograms when clinically indicated. The team adjusts visit frequency according to risk. A clinic can order or review tests, but it cannot provide the same continuous monitoring and rapid emergency response as a hospital.

Inpatient care is used when serial clinical observations, correction of electrolyte problems, cardiac assessment, controlled management of serious dehydration, or medically supervised nutritional rehabilitation cannot safely occur outside the hospital. This distinction is central to NICE recommendations on inpatient care and Royal College of Psychiatrists emergency guidance. Hospitalization may also be required for acute psychiatric danger; the setting must have the medical and mental health capabilities that the person actually needs.

Meals, nutritional rehabilitation, and psychological treatment

Both settings should offer evidence-based psychological care and nutrition support appropriate to the diagnosis. An outpatient team works collaboratively to restore reliable nourishment and reduce eating-disorder behaviors in ordinary life. Some patients benefit from structured support from family or carers; others need a more independent plan. Clinical assessment determines what is appropriate.

An inpatient team can supervise nutrition and monitor early medical responses more continuously. Refeeding-related electrolyte shifts are potentially serious, especially in people with substantial malnutrition, regardless of visible body size. Specific hospital protocols are clinical procedures, and the appropriate monitoring and nutrition plan are determined by trained staff. The hospital phase is often focused on medical stabilization; psychological recovery generally continues well after discharge.

Privacy, freedom, family participation, and cost

Outpatient treatment generally permits more independence and less disruption to education, employment, caregiving, and personal relationships. Its practical strength is that skills are practiced in real life. Its demands include attending appointments, access to meals and supportive people, and timely escalation if clinical status worsens. Services may be limited by local availability or insurance.

Hospital care provides greater supervision but interrupts ordinary routines. Some patients experience relief from reduced day-to-day demands, while others experience loss of privacy or autonomy, separation from family, or difficulty transitioning home. Families should be involved as appropriate, and age-specific educational and family supports matter. Total costs vary by coverage, hospital type, benefits, length of stay, and region; no single setting is uniformly affordable or accessible.

Where do IOP, PHP, day programs, and residential care fit?

The phrase inpatient versus outpatient can hide several important steps between weekly specialist visits and a hospital admission. Care is a continuum. Names and admission standards vary across countries, insurers, and providers, so the actual clinical capabilities of a program matter more than its marketing label.

Intensive outpatient programs (IOP)

An intensive outpatient program generally offers multiple sessions or blocks of structured care per week while the person continues living at home. Programs may include individual and group psychotherapy, supported eating occasions, nutrition work, skills practice, family sessions, and psychiatric review. Medical monitoring may be performed by the program or coordinated externally. IOP is usually appropriate only when overnight supervision and hospital-level care are unnecessary.

Partial hospitalization (PHP) or day treatment

PHP or day hospital treatment provides substantial support during part of the day, often across several days per week, while the patient sleeps outside the facility. It may include supervised meals, psychological treatment, nutritional care, and clinical monitoring. Some programs have strong medical capabilities, but PHP cannot be assumed equivalent to hospital inpatient care. Safe overnight circumstances and capacity to manage deterioration outside program hours are part of the placement decision.

Residential treatment

Residential eating-disorder care provides an overnight therapeutic setting with a structured recovery routine. It is often designed for someone requiring sustained behavioral and nutritional support while medically stable enough to be outside an acute medical hospital. Residential programs differ greatly in staffing, laboratory access, physician availability, admission criteria, ability to manage crises, and arrangements for medical transfers. Residential care should never be described as a substitute for acute medical stabilization when hospital care is indicated.

The levels-of-care guide maps all five commonly discussed settings and the reasons for moving among them. This article concentrates on the practical differences between outpatient life and overnight admission.

When is inpatient eating disorder treatment medically necessary?

Hospitalization becomes important when a person's physiological condition or immediate psychiatric risk makes outpatient care unsafe. Decisions require an examination and an integrated medical and mental health assessment. The Society for Adolescent Health and Medicine (SAHM) position paper, the American Academy of Pediatrics (AAP) clinical report, and NICE provide professionally defined hospitalization considerations.

Warning patterns clinicians assess

Clinicians evaluate vital signs and their changes with position, heart rhythm or electrocardiogram abnormalities, electrolyte disturbances, dehydration, hypoglycemia, evidence of organ dysfunction, fainting, seizures, failure to grow as expected, marked changes in weight trajectory, inability to obtain sufficient nourishment, and behaviors that cannot be made safe in the community. Acute suicidal intent or another serious mental health emergency also changes the setting decision. These findings must be interpreted together rather than treated as a home checklist.

SAHM identifies medical instability, electrolyte abnormalities, dehydration, acute food refusal, uncontrolled bingeing or purging, failure of outpatient treatment, acute medical complications, developmental concerns, and psychiatric or medical comorbidity that prevents safe outpatient care as factors supporting hospitalization in adolescents and young adults. Thresholds in professional documents are clinical decision supports with age-specific interpretation, not instructions for deciding whether one is 'sick enough.' Read the full SAHM position.

Severe malnutrition and rapid nutritional decline can be dangerous at any weight. People with atypical anorexia nervosa may meet the characteristic psychological and behavioral features of anorexia while remaining above the low-weight criterion, yet develop serious cardiovascular and metabolic compromise. ARFID can also lead to marked nutritional deficiencies or medical risk without weight- or shape-based concerns. Clinical risk depends on current physiology, trajectory, behavior, and comorbidity, not simply the number on a scale.

Medical inpatient care versus psychiatric inpatient care

Medical inpatient admission is intended to stabilize urgent physical problems, such as dangerous cardiac findings, electrolyte derangements, severe dehydration, or major metabolic complications. A psychiatric inpatient unit may be necessary for acute psychiatric safety needs. A specialized eating-disorder inpatient program may integrate medical and psychological expertise, but admission should match the actual ability to manage the medical risks present. Sometimes people transfer between medical and specialist settings as their needs change.

A person with chest pain, loss of consciousness, seizures, confusion, severe weakness, signs of significant dehydration, or imminent risk of self-harm needs immediate emergency assessment. Emergency evaluation is appropriate even if a regular eating-disorder appointment is already scheduled. The medical-emergency warning-sign guide discusses urgent recognition in more detail.

When is outpatient care a safe and effective option?

Outpatient care is often a preferred starting point when the person is medically and psychiatrically stable, can access an eating-disorder-informed multidisciplinary team, has a viable nutrition and monitoring plan, and can receive adequate support between visits. Stability must be reassessed as recovery proceeds. Treatment may be intensive despite being outpatient: psychotherapy, medical review, nutrition rehabilitation, and family work can all be coordinated without overnight admission.

Being offered outpatient care is a clinical judgment about the present safety and support needs, not a statement that the disorder is minor. Some severe psychological symptoms require sustained specialist outpatient therapy after an initial hospital episode. Others improve through evidence-based outpatient treatment without hospitalization. Clinical teams should make escalation plans explicit at the outset, including who monitors physical health and what findings require urgent reassessment.

The American Psychiatric Association treatment guideline and NIMH eating-disorders overview describe integrated care including psychotherapy, medical monitoring, nutritional treatment, and medication when clinically indicated for a particular diagnosis or associated condition. The expected form of care changes across diagnosis, age, and response.

How clinicians decide which setting fits a person

1. Diagnosis, symptom pattern, and developmental context

An assessment starts by clarifying the likely feeding or eating disorder, its duration and course, restriction, binge-eating or compensatory behaviors, and effects on daily life. A diagnosis can guide psychotherapy selection but does not automatically determine the level of care. The clinician evaluates the person's age, growth pattern, developmental needs, and relevant medical history. The clinical-assessment guide explains how formal diagnosis differs from screening and symptom description.

2. Present physical and psychiatric risk

The team reviews physical examination findings, relevant tests, medications, fainting episodes, rapid changes, nutritional deficiencies, cardiac symptoms, suicidal risk, and co-occurring conditions. Screening scales may contribute background information, but their scores neither establish an eating-disorder diagnosis nor determine admission. A normal single blood test does not rule out a severe eating disorder, and physiological risk can evolve.

3. The feasibility of safe treatment outside hospital

Clinicians ask whether the patient can reliably attend care, receive adequate support with nourishment, tolerate a workable home plan, access prompt medical monitoring, and reach emergency services if needed. For an adolescent, caregivers' capacity and school arrangements may be central. For an adult, housing security, work conditions, disability accommodations, finances, or lack of safe support can affect what level of care is feasible. These are care-planning factors rather than judgments about motivation or character.

4. Response, preferences, access, and shared decisions

Current response matters. Continued medical deterioration, persistent inability to nourish safely, worsening psychiatric risk, or repeated disruption of outpatient treatment can justify stepping up. When multiple settings are medically safe, patient preferences, autonomy, family circumstances, cultural and accessibility needs, and evidence-based treatment availability should shape shared decisions. Insurance criteria can influence access but cannot replace clinical judgment.

If a placement decision seems unclear, request a written explanation of the medical and psychiatric reasons, the proposed treatment goals, the expected monitoring, and the conditions for moving to a different level. A second specialist opinion may be appropriate when the clinical situation permits.

Does inpatient treatment work better than outpatient treatment?

Research does not support the simple claim that a more restrictive treatment setting always produces better long-term outcomes. Hospital admission is necessary for some acute medical and psychiatric emergencies; that safety function should be distinguished from comparative effectiveness in stable patients who could appropriately be treated in more than one setting.

The Cochrane systematic review included five controlled trials across anorexia nervosa and bulimia nervosa, involving 566 participants overall. It found insufficient high-quality evidence to establish one setting as universally superior. Some findings suggested greater completion of treatment partly or wholly outside hospital, but the evidence was low or very low certainty. Those trials were small and heterogenous, and they did not randomize people who required emergency hospital care to unsafe alternatives.

A 2015 systematic review by Madden and Hay examining randomized anorexia nervosa treatment-setting comparisons found preliminary support for less restrictive settings where clinically suitable, alongside the need for more rigorous evidence. That finding does not authorize outpatient care for medically unstable patients.

What randomized trials found

In the 2014 ANDI randomized noninferiority trial, adolescents with anorexia nervosa received an initial brief inpatient phase and were then assigned to day-patient treatment or continued hospitalization. Day-patient treatment met the trial's noninferiority criterion for its primary weight-related outcome at 12 months and could be less costly. This supports a carefully planned step-down option for a selected adolescent population; it does not mean all adolescents or diagnoses are suitable for day treatment.

The more recent DAISIES trial report investigated a stepped day-treatment approach versus usual inpatient treatment in adults with anorexia nervosa. Only 15 participants were randomized, compared with a much larger recruitment target. The small sample and difficulty recruiting due partly to strong treatment preferences prevented a definitive comparison. Similar observed improvements and greater reported acceptability of day treatment in that trial are exploratory findings, not evidence that day care universally replaces inpatient treatment.

What broader observational evidence can and cannot establish

A 2023 systematic review and meta-analysis of 62 studies reported improvements across several outcomes among adults receiving intensive eating-disorder treatment, including eating-disorder symptoms, depression, and quality of life, with physical improvement among underweight samples. Marked differences among studies limit comparative conclusions. People admitted to higher-intensity care often enter treatment with greater medical and psychological severity, so simply comparing their outcomes with less severe outpatient groups can produce misleading conclusions about setting effectiveness.

Many studies also emphasize anorexia nervosa and underrepresent other disorders, men, gender-diverse patients, older adults, and a full range of body sizes and socioeconomic circumstances. Treatment content differs between programs; the same term, such as residential or day hospital, can describe very different interventions. Strong conclusions about the best setting for each person remain limited.

How treatment setting differs by eating disorder diagnosis

Anorexia nervosa and atypical anorexia nervosa

Restriction, malnutrition, cardiac complications, anxiety about eating, and difficulty restoring nourishment often shape placement. In adolescents, growth and developmental trajectory deserve particular attention; an individual can experience severe physiological instability without appearing underweight. Inpatient medical care may be needed for stabilization, followed by specialist outpatient psychotherapy and nutritional rehabilitation. When outpatient care is safe, it can offer a meaningful setting for continuing recovery skills and family-supported care.

Bulimia nervosa and other purging presentations

Many patients with bulimia nervosa can receive evidence-based outpatient psychotherapy and coordinated medical evaluation. More intensive care may be needed if purging-related electrolyte abnormalities, cardiovascular effects, uncontrolled behaviors, psychiatric emergencies, or inability to engage safely in outpatient care develop. Apparent weight stability cannot be used to dismiss medical risk. Diagnostic distinctions between bulimia nervosa and purging presentations under OSFED require specialist evaluation.

Binge eating disorder

For many people with binge eating disorder, outpatient evidence-based psychological treatment is appropriate. Hospitalization is not generally a standard treatment solely because binge episodes occur. Another medical emergency, severe psychiatric comorbidity, or a more complex eating disorder can change the recommendation. Care planning should address distress, functional impact, and other health conditions without assuming that BMI measures treatment urgency or eating-disorder severity.

ARFID, OSFED, UFED, and less familiar feeding disorders

ARFID involves restrictive or avoidant eating that may reflect sensory sensitivity, limited interest in eating, or fear of aversive consequences; it does not require fear of weight gain. Medical complications, nutritional deficiencies, age, and available supports determine treatment intensity. The ARFID treatment guide examines tailored nutritional and psychological care. OSFED and UFED are clinical categories, and their medical risk should be evaluated on the actual presentation rather than dismissed because criteria for another named disorder are not met.

Pica and rumination disorder require assessment for associated medical complications and underlying contributors. Orthorexia is a research and popular-language construct rather than a standalone DSM-5-TR eating-disorder diagnosis. Placement should follow the person's clinical risks and applicable diagnosed conditions, not a label obtained online.

Special considerations for children, adolescents, and young adults

Growth disruption, delayed puberty, developmental changes, nutritional needs, school participation, and caregiver support make pediatric placement more complex. Pediatricians may monitor growth charts and physical signs over time rather than rely on adult BMI categories. AAP guidance emphasizes early identification, specialist referral when available, and escalation when adequate improvement does not occur with outpatient treatment.

Family-based treatment can be central for many adolescents with anorexia nervosa and may help families support regular nourishment and recovery while the young person lives at home. This is a structured clinical approach, not an invitation for families to carry the entire burden without professional care. Age-appropriate inpatient units should facilitate family participation and educational continuity when feasible. Explore Family-Based Treatment (FBT) for Adolescent Eating Disorders for its appropriate uses and limitations.

Young adults moving between pediatric and adult services may face discontinuities in insurance, housing, school, and clinical follow-up. The transition itself should be explicitly coordinated, including responsibility for medical monitoring, prescriptions, nutrition plans, and emergency escalation.

Psychotherapy, nutritional treatment, and medication across settings

An overnight stay is not a psychological treatment method. The core therapeutic plan should be matched to the diagnosis: structured eating-disorder-focused cognitive behavioral treatment may be relevant for bulimia nervosa and binge eating disorder; family-based treatment is important in selected adolescent presentations; adults with anorexia nervosa may receive specialist psychotherapies adapted to their needs; and ARFID care may draw on condition-specific exposure-based and family approaches. The evidence-based eating-disorder treatment hub compares therapies and their diagnostic targets.

Medical and nutritional rehabilitation can be necessary at any level, with appropriate supervision. In a hospital, monitoring is more continuous and teams can respond to acute instability; outside the hospital, clinicians coordinate an individualized plan and adjust follow-up to risk. Neither setting should promise recovery solely through weight change. Cognitive, emotional, relational, functional, and nutritional progress all matter.

Medication can support selected eating-disorder diagnoses or co-occurring disorders, but it does not substitute for indicated medical monitoring or evidence-based psychological treatment. Medication choice and monitoring must account for comorbidities, side effects, age, and the current nutritional state. The NIMH treatment overview summarizes why care commonly combines psychotherapy, medical treatment, and nutrition support.

How long does inpatient treatment last?

There is no universally appropriate number of hospital days or a fixed outpatient course. A short medical admission may focus on immediate physiological stabilization and establishing a safe transition. A specialist inpatient therapeutic stay may be longer when intensive clinical needs persist. Duration depends on the specific medical and psychological goals, the person's progress, and the availability of a viable next setting.

Discharge should follow a clinical plan rather than a single target number. NICE guidance advises against ending admission merely because someone has attained a particular weight and recommends collaborative review of inpatient goals and alternatives. A person can leave a hospital medically stabilized while still needing months or longer of specialist treatment and follow-up.

What happens when stepping up from outpatient care?

Stepping up means moving to greater support because current care is insufficient for safety or recovery needs. Ideally the outpatient and receiving teams share a clinical summary, recent medical information, psychiatric risks, current medications, a nutrition and behavioral care plan, and the agreed goals for admission. When deterioration is immediate, emergency evaluation takes priority over routine intake paperwork.

A clear explanation from the team should identify which risks require the higher setting, what the treatment environment can provide, how family and other supporters participate, and how progress will be reviewed. Patients may have concerns about privacy, involuntary elements, costs, school, work, or disability support; discussing these early improves preparation when time and safety allow.

How does someone step down from inpatient to outpatient care?

Stepping down is a planned transfer to a lower level of supervision while continuing treatment. It may be from hospital to PHP, residential care, IOP, or specialist outpatient visits depending on medical stability and available services. A hospital discharge does not mean the eating disorder has resolved. Handoffs should name who is responsible for examinations, laboratory monitoring, psychotherapy, nutrition support, prescriptions, family contact, and responding to renewed risk.

NICE's quality standard on coordinated care calls for services to plan admission, treatment goals, discharge, and community follow-up together. Before leaving a higher level of care, patients and caregivers should receive a practical timetable, warning signs that warrant re-evaluation, a contact route for urgent concerns, and arrangements for missing or delayed appointments.

The first weeks after a transition can introduce new demands: managing meals outside staff supervision, returning to ordinary activities, navigating familiar triggers, and renegotiating family roles. The outpatient team may intensify follow-up during this period. Ongoing attention to mental health, eating behavior, physical health, and functioning helps prevent abrupt gaps in care. For the longer course, see Eating Disorder Recovery: Stages, Challenges, and Support.

What about insurance coverage and finding treatment in the United States?

In the United States, some insurers apply prior authorization, network restrictions, benefit criteria, and medical-necessity reviews to residential, PHP, IOP, and inpatient services. Program names and coverage definitions vary. Families can ask a prospective provider and insurer how medical monitoring, laboratory tests, dietitian services, psychotherapy, medications, emergency transfers, telehealth follow-up, and out-of-network care are handled. A benefits decision is an administrative determination; clinical risk must still be evaluated by qualified professionals.

Useful records for coordination include a specialist assessment, the clinician's reasons for the proposed setting, recent vital signs and relevant tests, treatment history, documentation of barriers to a lower level of care, and a step-down plan. When coverage is denied, request the precise reason and the relevant appeal process from the insurer and treating team. Immediate medical or psychiatric danger calls for emergency services regardless of an insurance authorization dispute.

Questions to ask a program before admission

Ask whether the program is a hospital medical unit, a psychiatric inpatient unit, a residential facility, PHP, or IOP; how often a physician evaluates patients; whether staff can perform or arrange required laboratory and cardiac monitoring; and what triggers emergency transfer. Confirm whether the program accepts the specific diagnosis and age group, what evidence-based therapies it offers, and whether family involvement and necessary accommodations are available.

Ask who coordinates discharge and community follow-up, whether the same clinical team can follow the patient between levels, what the expected treatment goals are, and how progress is reviewed. Discuss privacy, educational and employment support, gender-affirming and culturally responsive care, disability and sensory accommodations, medication management, and costs. A program's stated intensity is meaningful only when its staff and procedures can meet the person's actual clinical needs.

Frequently asked questions

Is inpatient eating disorder treatment always better than outpatient treatment?

No single setting is best for every patient. Inpatient care is essential when immediate medical or psychiatric risk requires 24-hour supervision; otherwise, evidence-based outpatient or day treatment may be appropriate and can preserve daily life. Comparative research is limited and should never override individual safety assessment.

Can I need hospitalization even if my BMI is in the typical range?

Yes. Rapid nutritional decline, dehydration, cardiac abnormalities, electrolyte changes, serious psychiatric risk, and other complications can occur across body sizes. Clinicians interpret weight in the context of age, growth, trajectory, physiology, behavior, and the broader medical picture.

Is residential treatment the same as inpatient hospitalization?

No. Residential care ordinarily provides an overnight therapeutic environment for patients stable enough to be outside an acute medical hospital. Hospital inpatient services can deliver a higher level of immediate medical intervention and monitoring. Exact capabilities differ across facilities, so ask each program directly.

What is the difference between PHP and IOP?

Both allow a person to live outside the program, but PHP/day care usually provides more treatment hours and greater daytime structure than IOP. Neither necessarily has hospital-level emergency or overnight monitoring. The precise schedule and clinical services vary by provider.

Will outpatient treatment include medical testing?

It often does when clinically indicated. The treating clinician decides whether to monitor vital signs, weight trajectory, relevant laboratory measures, cardiac findings, nutritional status, and other concerns. The frequency depends on risk and response, and a significant change may require urgent hospital evaluation.

Does hospitalization cure an eating disorder?

Hospital care can stabilize serious medical or psychiatric problems and support early treatment. Recovery also involves sustained work on eating-disorder thoughts and behaviors, nutritional rehabilitation, emotional functioning, and daily life. Many patients need structured care after discharge.

How do clinicians decide when someone can leave hospital?

They review acute medical and psychiatric stability, progress toward admission goals, the safety and availability of the next setting, and a coordinated follow-up plan. A particular weight or number of hospital days is not a sufficient discharge criterion by itself.

What if outpatient treatment is not working?

Contact the treatment team promptly for reassessment. The next step may be a different psychotherapy, more coordinated medical or nutritional care, IOP, PHP, residential treatment, or inpatient care if safety requires it. Emergency symptoms require immediate care rather than waiting for a routine treatment review.

Can telehealth replace inpatient care?

Telehealth may deliver selected outpatient psychotherapy and care coordination when appropriate. It cannot replace inpatient management of medical instability, dangerous electrolyte abnormalities, acute psychiatric emergencies, or the need for continuous observation and interventions.

What should relatives do when someone refuses treatment?

Relatives can communicate concrete observations without blame, offer to help arrange a specialist medical assessment, and ask the person's clinician about the appropriate response to immediate risk. Decisions about capacity, consent, guardianship, and legally mandated care are jurisdiction- and circumstance-specific clinical and legal matters. Emergency risk needs urgent professional assessment.
