Where the Hospital Ends: Hospital at Home and the Changing Line Between Inpatient and Ambulatory Care

Two Sectors, Traditionally Separate

The U.S. delivery system has long been organized around a division between inpatient and ambulatory care. Inpatient care is delivered to patients formally admitted to a hospital, usually for at least one overnight stay, when their condition requires round-the-clock nursing, frequent physician assessment or services that only a hospital can provide. Ambulatory care covers everything delivered to patients who go home the same day: physician offices, clinics, ambulatory surgery centers, urgent care, hospital outpatient departments and home health (Shi & Singh, 2022). The division matters because it shapes how organizations are licensed and accredited, how they are paid and which clinicians work where. Hospitals are paid a fixed amount per admission under Medicare's prospective payment system, while most ambulatory services are paid per visit or procedure.

The two sectors depend on each other. Ambulatory care sends patients to the hospital when they become too sick to manage at home, and the hospital sends them back with a discharge plan that ambulatory providers must carry out. Most failures of coordination in the system happen at exactly these crossings.

Why Care Keeps Moving Out of the Hospital

For four decades, care has been migrating from inpatient to outpatient settings. Several forces drove the change. Anesthesia and minimally invasive surgery made many procedures safe without an overnight stay. Prospective payment gave hospitals a fixed amount per admission, which rewarded shorter stays. Payers and employers steered patients toward outpatient settings because they usually cost less. Patients generally preferred to recover at home. The result is that hospitals now earn a growing share of their revenue from outpatient services, and many have built or bought ambulatory networks to keep patients within their systems. The line between the sectors is no longer set by the patient's condition alone; it is set by what can be done safely, and paid for, outside a hospital bed.

Hospital at Home: The Shift Taken to Its Limit

Hospital at home takes the shift further than any other model. Instead of moving procedures or recovery out of the hospital, it moves the acute admission itself. Patients who would otherwise be admitted for conditions such as pneumonia, heart failure, chronic obstructive pulmonary disease exacerbations or cellulitis are treated at home by a team that provides daily clinician visits, nursing care, intravenous medications, oxygen, point-of-care testing and remote monitoring, with the option of transfer to the hospital if the patient worsens.

The evidence is encouraging. In an early multisite study of 455 older adults, 69 percent of patients offered hospital at home at two of the three sites chose it, length of stay was shorter (3.2 days versus 4.9 days) and mean cost was lower (5,081 dollars versus 7,480 dollars) than in the hospital, while quality standards were met at similar rates (Leff et al., 2005). A later randomized controlled trial of 91 adults admitted through the emergency department found that the adjusted cost of the acute episode was 38 percent lower at home, and that home patients had fewer laboratory orders and imaging studies, spent less of the day lying down and returned to the hospital less often over the following month, 7 percent against 23 percent (Levine et al., 2020). Both studies were small and involved selected patients, and in the randomized trial 63 percent of eligible patients declined, so the model does not suit everyone.

What the Model Changes for Each Sector

For hospitals, hospital at home offers a way to expand capacity without building beds, which matters when emergency departments are full of patients waiting for admission. It also asks them to run operations they are not built for: scheduling nurse visits across a region, delivering equipment and medications to homes, and monitoring patients remotely. For ambulatory providers, it creates a new handoff. The patient's primary care physician, home health agency and pharmacy must know that the patient is technically an inpatient, even though the patient is in a familiar living room.

Payment is the constraint that decides whether the model spreads. Medicare's hospital payment rules historically assumed a patient in a hospital bed. In November 2020, during the COVID-19 pandemic, the Centers for Medicare & Medicaid Services created the Acute Hospital Care at Home program, which lets approved hospitals receive inpatient payment for patients treated at home if they meet specific requirements (Centers for Medicare & Medicaid Services [CMS], 2024). The program has depended on temporary waivers and congressional extensions, and hospitals have been cautious about investing in a service whose payment might end.

What It Means for Patients and Families

The model also shifts work and risk onto households, which is easy to overlook when the evidence focuses on cost. A patient treated at home needs a safe place to stay, a working telephone or internet connection for monitoring, and often a family member who can be present, notice changes and call the team. Patients who live alone, lack stable housing or have limited English proficiency may be excluded by eligibility rules or may decline because the arrangement feels unsafe. That creates an equity question for the delivery system: if hospital at home becomes a large part of acute care, patients with fewer resources could be concentrated in crowded hospitals while others recover in their own homes. Programs can reduce this risk by supplying equipment and connectivity, offering interpreter services on every visit and including caregivers in planning. For many older patients, however, the benefits are substantial. They avoid the disorientation, immobility and sleep disruption that often accompany a hospital stay, and they recover among their own routines and belongings, which the randomized trial reflected in its finding that home patients spent less of the day lying down.

Conclusion

Hospitals and ambulatory care have always been interdependent, but hospital at home shows that the boundary between them is increasingly a matter of payment and organization rather than place. Where a patient can be monitored, treated and visited safely, the hospital can extend into the home. That makes coordination across the old boundary more important, not less, and it means that payment policy, not technology, will largely decide how far the shift goes.
