Hospital-at-Home: Ready for Prime Time? A Critical Appraisal for Hospitalists

Hospital-at-Home: Ready for Prime Time? A Critical Appraisal for Hospitalists

Hospital medicine has traditionally been defined partly by geography.

The patient is sick enough to require hospital-level care.

Therefore, the patient goes to the hospital.

But what if hospital-level care could be delivered somewhere else?

That is the premise behind Hospital-at-Home (HaH).

Instead of occupying a traditional inpatient bed, carefully selected patients receive acute hospital-level care in their homes through a combination of:

• Physician oversight
• Nursing care
• Remote monitoring
• Diagnostic testing
• Medication delivery
• In-home clinical services
• Telemedicine
• Rapid escalation pathways

For hospitalists facing ED boarding, hospital crowding, limited bed capacity, and growing demand for patient-centered care, Hospital-at-Home raises an important question:

Which patients actually need a hospital bed—and which patients need hospital-level care that can safely be delivered somewhere else?

A large pragmatic randomized trial provides important new evidence.

But the answer is more complicated than simply declaring Hospital-at-Home ready to replace conventional hospitalization.

What Is Hospital-at-Home?

Hospital-at-Home is not the same as:

• Home health
• Routine telemedicine
• Early discharge
• Outpatient care
• Skilled nursing
• Remote patient monitoring alone

A true Hospital-at-Home program provides hospital-level acute care in the patient’s home as a substitute for at least part of a conventional hospitalization.

Depending on the program, this may include:

• Physician evaluation
• Nursing visits
• IV medications
• Laboratory testing
• Imaging
• Oxygen
• Remote physiologic monitoring
• Medication management
• Physical therapy
• Pharmacy services
• Care coordination
• Emergency escalation

That distinction matters.

Hospital-at-Home should not mean:

less care at home.

It means:

hospital-level care delivered through a different infrastructure.

Why Hospital-at-Home Matters to Hospitalists

Hospitalists increasingly practice in hospitals facing:

• ED boarding
• High occupancy
• Nursing constraints
• Delayed discharges
• Capacity shortages
• Growing patient volumes

These problems are interconnected.

An admitted patient boarding in the ED may be waiting because every inpatient bed is occupied.

For more on that problem, read When the Hospital Is Full: A Smarter Approach to Caring for Medicine Patients Boarding in the ED.

Hospital-at-Home introduces another potential capacity strategy:

What if some patients receiving hospital-level care did not need to occupy a traditional hospital bed at all?

The 2025 Randomized Hospital-at-Home Trial

One of the strongest contemporary studies evaluating this question was:

Maniaci MJ, Sangaralingham LR, Behnken EM, et al. Safety in a hybrid hospital-at-home program versus traditional inpatient care: A pragmatic randomized controlled trial.

The study evaluated a hybrid Hospital-at-Home model across three Mayo Clinic hospitals.

A total of 1,150 acutely ill adults requiring hospital-level care were randomized to:

Hybrid Hospital-at-Home

or

Traditional inpatient hospitalization.

What Did Hospital-at-Home Look Like?

The intervention was not simply a video visit.

Physicians provided care virtually while patients received support from an in-home clinical team and technology infrastructure.

This is important when interpreting the results.

The trial evaluated an established system of hospital-level home care.

It did not evaluate sending patients home with a blood-pressure cuff and telling them to call if they felt worse.

What Was the Primary Outcome?

The primary outcome was a composite of:

30-day all-cause mortality or unplanned readmission.

The trial was designed as a noninferiority study.

That means the primary question was not:

“Is Hospital-at-Home better than conventional hospitalization?”

Instead, investigators asked whether Hospital-at-Home produced outcomes that were not unacceptably worse than traditional hospitalization according to a prespecified margin.

That distinction is essential.

What Were the Results?

The primary composite outcome occurred in:

17.3% — Hospital-at-Home

versus

19.8% — Traditional hospitalization.

Hospital-at-Home met the trial’s prespecified criterion for noninferiority.

This provides reassuring evidence that, among appropriately selected patients receiving care through this particular HaH model, short-term outcomes were comparable to conventional hospitalization according to the study’s primary endpoint.

What About Readmissions?

Thirty-day unplanned readmission occurred in:

14.7% — Hospital-at-Home

versus

17.5% — Traditional hospitalization.

The difference was not statistically significant.

Therefore, the study should not be interpreted as proving that Hospital-at-Home reduces readmissions.

What About Mortality?

Thirty-day mortality was:

4.4% — Hospital-at-Home

versus

3.3% — Traditional hospitalization.

The difference was not statistically significant.

Importantly, no Hospital-at-Home patient died while actively receiving hospital care at home.

Still, hospitalists should resist overstating the findings.

The trial does not demonstrate that Hospital-at-Home reduces mortality.

It also does not establish that HaH increases mortality.

The appropriate conclusion is that the trial met its prespecified noninferiority criterion for the composite primary outcome.

Patient Comfort Was Substantially Better

One of the clearest differences involved patient experience.

Patients reporting that they felt very or extremely comfortable included:

84.4% — Hospital-at-Home

versus

60.9% — Traditional hospitalization.

That is a substantial difference.

Comfort should not automatically be dismissed as a secondary or unimportant endpoint.

Traditional hospitalization can expose patients to:

• Sleep disruption
• Noise
• Immobility
• Unfamiliar surroundings
• Loss of independence
• Repeated interruptions

For appropriately selected patients, receiving care in a familiar environment may have meaningful value.

Hospital-at-Home Is Not for Every Patient

This may be the most important limitation.

Hospital-at-Home depends heavily on patient selection.

A patient must be appropriate from both a:

clinical perspective

and

social/environmental perspective.

Clinical Selection

Programs need to determine whether the patient’s illness can safely be managed outside a traditional hospital.

Patients with conditions involving:

• Rapid deterioration
• Hemodynamic instability
• Intensive monitoring requirements
• Immediate procedural needs
• High oxygen requirements
• Frequent bedside interventions
• Complex critical-care needs

may not be appropriate.

Hospitalists managing patients at risk of deterioration should maintain a low threshold for escalation when clinically indicated.

For additional bedside critical-care review, see ICU Pearls for Hospitalists.

Social and Environmental Selection

Clinical stability is not enough.

The home environment also matters.

Programs may need to consider:

• Housing stability
• Electricity
• Internet or cellular connectivity
• Physical accessibility
• Distance from emergency services
• Caregiver availability when required
• Medication access
• Ability to communicate
• Safety of the home environment

A patient can be medically appropriate for Hospital-at-Home but environmentally inappropriate.

Hospital-at-Home Requires Infrastructure

This is another critical lesson for health systems.

Hospital-at-Home is not simply a physician staffing model.

It requires an operational ecosystem.

Potential components include:

Physician Coverage

Physicians must be available to evaluate patients, respond to changes, and coordinate care.

Nursing

Patients may require scheduled or urgent nursing assessment.

Monitoring

Programs may use technology to track physiologic variables.

Laboratory Testing

Blood tests must be obtained, transported, processed, and reviewed.

Medications

Hospitals need mechanisms for rapidly delivering:

• Oral medications
• IV medications
• Fluids
• Other therapies

Imaging

Some programs may need pathways for mobile or facility-based imaging.

Logistics

Equipment and supplies must reach the patient’s home reliably.

Escalation

Hospitals need a clear process for rapidly transferring patients back to conventional hospital care when necessary.

Without these systems, the model being delivered is not equivalent to the model evaluated in successful Hospital-at-Home studies.

Hospitalists May Become Virtual Ward Physicians

Hospital-at-Home also changes the concept of the hospitalist’s workplace.

A future hospitalist census might include:

10 patients physically in the hospital

plus

5 patients receiving hospital-level care at home.

The physician may manage both through a combination of:

• Electronic health records
• Video visits
• Remote monitoring
• Nursing communication
• In-home teams
• Digital diagnostics

This creates new workload questions.

How should a HaH patient count toward hospitalist census?

How much physician time does remote management require?

How many home patients can one physician safely manage?

How should workload account for escalation risk?

These questions deserve the same attention given to conventional hospitalist census.

For a broader discussion of workload, read How Many Patients Can a Hospitalist Safely Manage? Evidence on Census, Workload & Patient Outcomes.

Hospital leaders can also review What Is the Ideal Hospitalist Census?.

Hospital-at-Home and Hospital Capacity

One of the most attractive potential benefits is capacity.

Imagine a hospital with:

• A full inpatient census
• Multiple admitted patients boarding in the ED
• Delayed transfers
• Limited physical beds

If carefully selected patients can receive hospital-level care at home, traditional beds may remain available for patients who truly require the physical infrastructure of the hospital.

Conceptually, HaH can function as a form of distributed hospital capacity.

But health systems should be cautious.

A home bed is not automatically equivalent to a hospital bed.

The necessary staffing and infrastructure still have to exist.

Hospital-at-Home and ED Boarding

Hospital-at-Home could potentially intersect with ED boarding in several ways.

Selected patients could potentially transition:

ED → Hospital-at-Home

rather than:

ED → wait for bed → inpatient floor.

This could potentially reduce demand for conventional beds in appropriately selected patients.

But screening and implementation must be reliable.

For a broader discussion of managing admitted patients before an inpatient bed becomes available, read When the Hospital Is Full.

Hospital-at-Home and Length of Stay

Hospital-at-Home should also be considered within the larger patient-flow strategy.

Hospitals frequently focus on reducing conventional inpatient length of stay through:

• Earlier discharge planning
• Multidisciplinary rounds
• Improved consultation
• Diagnostic efficiency
• Better post-acute coordination

For additional evidence-based strategies, read Reducing Hospital Length of Stay.

HaH introduces a different possibility:

Some hospital-level days may occur outside the physical hospital.

That changes how health systems think about capacity.

Hospital-at-Home and Delayed Discharges

Not every capacity problem can be solved through HaH.

Many patients remain hospitalized because of:

• Skilled nursing placement
• Rehabilitation
• Insurance authorization
• Transportation
• Home equipment
• Housing
• Caregiver limitations
• Other social barriers

Some of these same factors may also prevent a patient from participating in Hospital-at-Home.

For more on these barriers, read Delayed Hospital Discharges: Hidden Causes, Rising Costs, and What Healthcare Leaders Can Do.

Hospital-at-Home vs Observation Care

Hospital-at-Home and observation medicine solve different problems.

Observation care is generally designed for patients who require additional evaluation or short-term treatment but may not need prolonged inpatient hospitalization.

Hospital-at-Home delivers hospital-level acute care outside the traditional hospital.

Both models can potentially help health systems use conventional inpatient beds more efficiently.

For additional discussion, see The Evidence: Observation Units Improve Hospital Efficiency.

Which Conditions May Be Appropriate?

Eligibility depends on the individual program.

Hospital-at-Home studies have included selected patients with conditions such as:

• Infection
• Heart failure
• COPD
• Asthma
• Other acute medical illnesses

Diagnosis alone should not determine eligibility.

Two patients with the same diagnosis can have very different:

• Acuity
• Oxygen requirements
• Hemodynamics
• Comorbidities
• Functional status
• Social circumstances

Selection must therefore be individualized.

Heart Failure at Home

Heart failure is particularly interesting because management may involve:

• Volume assessment
• Diuretics
• Laboratory monitoring
• Medication adjustment
• Weight monitoring

Some carefully selected patients may be candidates for home-based hospital care.

Others may require conventional hospitalization because of:

• Hemodynamic instability
• Severe respiratory distress
• Significant arrhythmia
• Need for intensive monitoring
• Other complications

For a broader clinical review, read Heart Failure in Hospital Medicine.

Hospital-at-Home and Acute Kidney Injury

Kidney function creates another important challenge.

Hospital-at-Home programs caring for patients at risk for AKI need reliable mechanisms for:

• Laboratory testing
• Medication review
• Fluid assessment
• Urine-output assessment when indicated
• Rapid response to deterioration

Technology may increasingly help identify high-risk patients, although prediction alone does not guarantee improved outcomes.

For more on that distinction, read Can AI Help Prevent Acute Kidney Injury? What Hospitalists Should Know About ESTOP-AKI.

Hospital-at-Home and Artificial Intelligence

Hospital-at-Home may eventually become an important environment for clinical AI.

Predictive systems could potentially help identify:

• Deterioration
• AKI risk
• Readmission risk
• Escalation needs
• Abnormal vital-sign trends

But the same principle that applies to inpatient AI applies here:

Prediction is not treatment.

Algorithms must be connected to effective clinical responses.

Remote monitoring that generates alerts without reliable clinical action may create noise rather than safety.

What Happens When the Patient Deteriorates?

Every Hospital-at-Home program needs a clear answer to this question.

Hospitals should establish:

• Escalation criteria
• Emergency communication
• Ambulance pathways
• Transfer protocols
• Physician availability
• Receiving-bed processes

A deteriorating patient cannot remain at home simply because the program wants to avoid transfer.

Clinical safety must take priority over maintaining the HaH census.

The Hidden Logistics Challenge

Traditional hospitals centralize resources.

Hospital-at-Home decentralizes them.

That changes operations dramatically.

Instead of moving the patient to the:

laboratory

pharmacy

imaging department

nursing unit

the system may need to move services toward the patient.

That creates logistical challenges involving:

• Transportation
• Staffing
• Scheduling
• Equipment
• Medication delivery
• Specimen handling
• Technology
• Geography

This may be one reason results from mature HaH programs should not automatically be assumed to generalize to every health system.

Geography Matters

Hospital-at-Home may be easier to operate in some geographic environments than others.

A health system serving a dense metropolitan area may be able to reach many patients efficiently.

A rural system may face:

• Longer travel distances
• Fewer available clinicians
• Connectivity limitations
• Longer emergency transport times

On the other hand, rural patients may also derive substantial value from receiving hospital-level care closer to home.

The operational tradeoffs may therefore differ substantially across health systems.

What About Cost?

Hospital-at-Home is sometimes promoted as a lower-cost model.

Some previous randomized research has demonstrated lower direct costs with home hospitalization.

But cost results are not uniform across every study or program.

Costs depend on:

• Program scale
• Staffing
• Geography
• Transportation
• Technology
• Utilization
• Patient selection
• Fixed infrastructure
• Reimbursement

Health systems should therefore evaluate their own total cost structure rather than assuming HaH will automatically save money.

Hospital-at-Home and Patient Experience

Patient experience may be one of the strongest arguments for the model.

At home, patients may have:

• Familiar surroundings
• Their own bed
• Their normal food
• Family nearby
• Greater mobility
• Less nighttime disruption

But preferences vary.

Some patients may feel safer in a traditional hospital.

Others may worry about burdening family members.

Shared decision-making should therefore be part of appropriate patient selection.

Caregiver Burden Must Not Be Ignored

A program can appear efficient partly because work shifts from the health system to family members.

Hospitals should therefore ask:

• Does the patient require a caregiver?
• What tasks will that caregiver perform?
• Is the caregiver willing?
• Is the caregiver able?
• What happens overnight?
• Who responds when the patient needs help?

Hospital-at-Home should not depend on unpaid family members quietly replacing hospital staff.

Equity Matters

Hospital-at-Home also raises equity questions.

Eligibility may be affected by:

• Housing
• Geography
• Technology
• Connectivity
• Social support
• Home safety

Programs should monitor whether eligibility criteria unintentionally create disparities in access.

A model designed around patient-centered care should not become available primarily to patients with the most resources.

The Federal Hospital-at-Home Framework

In the United States, Hospital-at-Home expanded substantially through the CMS Acute Hospital Care at Home initiative.

The federal framework allows qualifying hospitals to deliver inpatient-level services in patients’ homes under specified waivers and program requirements.

For hospital leaders, the policy environment is important because the sustainability of Hospital-at-Home depends not only on clinical evidence but also on:

• Regulation
• Reimbursement
• Quality reporting
• Operational requirements

Hospitals considering HaH should review current CMS requirements rather than relying on older pandemic-era assumptions.

How Should Hospitalists Evaluate a Hospital-at-Home Program?

Hospitalists considering participation should ask:

Patient Selection

Who qualifies?

Who does not?

Clinical Responsibility

Who is the attending physician?

Physician Workload

How many patients does each physician manage?

Nursing

How frequently are patients seen in person?

Monitoring

What physiologic data are available?

Diagnostics

How quickly can labs and imaging be obtained?

Medications

How are urgent medications delivered?

Overnight Coverage

Who responds at 2 AM?

Escalation

How quickly can a deteriorating patient return to the hospital?

Geography

How large is the service area?

Technology

What happens when technology fails?

Caregivers

What responsibilities are expected of family members?

Quality

What outcomes are tracked?

These are not peripheral details.

They determine whether Hospital-at-Home is actually hospital-level care.

What Outcomes Should Hospitals Measure?

A mature program should monitor more than enrollment volume.

Important outcomes include:

• Mortality
• Readmission
• Emergency transfer
• Escalation to conventional hospitalization
• Adverse events
• Falls
• Medication errors
• Length of stay
• Cost
• Patient experience
• Caregiver experience
• Functional outcomes
• Physician experience
• Nursing experience

Hospitals should also examine outcomes among patients who were considered for HaH but were not eligible.

That can help reveal selection patterns.

Is Hospital-at-Home Ready for Prime Time?

The answer depends on what we mean.

If the question is:

“Is there credible randomized evidence that appropriately selected patients can receive hospital-level care at home with outcomes comparable to conventional hospitalization?”

The answer is increasingly yes.

If the question is:

“Should Hospital-at-Home replace traditional hospitalization?”

No.

Traditional hospitals remain essential for patients requiring:

• Intensive monitoring
• Critical care
• Procedures
• Immediate diagnostics
• Rapid escalation
• Complex multidisciplinary resources

Hospital-at-Home is better understood as an additional site of hospital-level care.

Hospital-at-Home Should Complement the Hospital

The future may involve several pathways:

Traditional inpatient hospitalization

for patients requiring conventional hospital infrastructure.

Observation care

for selected patients needing short-term evaluation and treatment.

Hospital-at-Home

for selected patients requiring hospital-level care who can safely receive it at home.

Outpatient care

for patients who do not require hospital-level services.

The challenge for hospital medicine is matching the right patient to the right setting.

Frequently Asked Questions

What is Hospital-at-Home?

Hospital-at-Home is a model in which selected acutely ill patients receive hospital-level services in their homes instead of receiving all of that care in a traditional hospital.

Is Hospital-at-Home the same as home health?

No. Home health generally provides a lower intensity of care. Hospital-at-Home is intended to substitute for hospital-level acute care.

Is Hospital-at-Home safe?

Randomized studies provide evidence that well-developed HaH programs can produce outcomes comparable to conventional hospitalization among appropriately selected patients.

This should not be generalized to every patient or every home-care model.

Does Hospital-at-Home reduce mortality?

The Mayo pragmatic randomized trial did not demonstrate a statistically significant mortality reduction.

Does Hospital-at-Home reduce readmissions?

Some studies have reported favorable readmission findings, but results vary. The Mayo trial did not demonstrate a statistically significant reduction in 30-day unplanned readmission.

Do patients prefer Hospital-at-Home?

Many patients report favorable experiences with home-based hospital care. In the Mayo trial, patient-reported comfort was substantially higher in the HaH group.

Can every hospital implement Hospital-at-Home?

Not necessarily.

Programs require significant clinical, logistical, technological, and administrative infrastructure.

Can hospitalists manage Hospital-at-Home patients virtually?

Yes. Some models use remote physician care combined with in-person nursing or other clinical services.

Is Hospital-at-Home just a way to solve bed shortages?

No.

Capacity is one potential benefit, but patient selection and clinical safety should determine eligibility.

Is Hospital-at-Home replacing hospitals?

No.

It is better viewed as an additional method of delivering hospital-level care to selected patients.

Bottom Line

Hospital-at-Home has moved beyond being merely an interesting experiment.

Large randomized evidence now suggests that, among appropriately selected patients cared for within a mature clinical infrastructure, a hybrid Hospital-at-Home model can achieve short-term outcomes comparable to traditional hospitalization while providing substantially greater patient-reported comfort.

But several cautions remain essential:

Noninferior does not mean superior.

Patient selection matters.

Infrastructure matters.

Escalation pathways matter.

Caregiver burden matters.

Equity matters.

And:

Hospital-at-Home is still hospital-level care.

The future of hospital medicine may therefore not be defined exclusively by the walls of the hospital.

The more useful question may be:

Which patients need the physical hospital—and which patients simply need the care that hospitals provide?
