The AI Prompt That Sent Me Down a $1.6 Trillion Rabbit Hole — And What I Found at the Bottom

Yesterday while driving home I asked my favorite AI tool (probably not the one you’re thinking of btw) to help me disrupt a $1.6 trillion industry.

It had thoughts.

Here’s the honest truth: hospital billing is infuriating. You already know that. I didn’t need to write an article to tell you.

But last week a coworker stopped me in the hallway. Her son needs back surgery. The quote? $427,000+. Not experimental. Not rare. Back surgery.

I couldn’t shake it.

So I did what modern-day 2026 futurist-minded healthcare entrepreneurs do. I opened an AI prompt and asked one simple question:

“If I wanted to build a business to disrupt expensive hospitals — what would I do?”

One day later, this article exists.

What came back wasn’t a theory. It wasn’t a startup pitch. It was a business plan but something already running, already proven, already inside some of the most respected health systems in America.

Most physicians have never heard of it.

Neither had I.

— Michael Tetreault, Editor-in-Chief, Concierge Medicine Today

Okay, so let’s start with the question physicians most often ask when they first hear about this: Is this theoretical, or is it actually happening somewhere?

It is happening. Right now. At scale. Across the country.

What Is Hospital-at-Home — And Is It Actually Real?

Hospital-at-Home (HaH) is a care delivery model in which patients who would traditionally be admitted to a hospital inpatient unit receive that same level of acute care — IV medications, daily nurse visits, remote vital sign monitoring, lab draws, physician oversight — in their own home.

The model is not new in concept. The HaH model was first introduced at Johns Hopkins in the United States in 1995, showing promising early results in length of stay, readmission rates, patient satisfaction, and hospital-acquired infections. [1] More specifically, Dr. John Burton of the Johns Hopkins School of Medicine and Dr. Donna Regenstreif of The John A. Hartford Foundation conceived the program to provide safe and effective hospital-level care in the home, with a geriatric study team led by Dr. Bruce Leff developing the foundational clinical model and eligibility criteria. [2]

For the first two decades, HaH remained largely a research-stage model. What changed everything was the pandemic. In November 2020, the Centers for Medicare & Medicaid Services launched the Acute Hospital Care at Home (AHCAH) waiver program, giving approved hospitals the ability to bill Medicare for home-based acute care. The floodgates opened.

As of February 2026, 366 hospitals across 139 health systems in 37 states had received approval to provide hospital services in patients’ residences. [3]

And critically — the regulatory foundation just became far more stable. In February 2026, the Consolidated Appropriations Act of 2026 was signed into law, extending the Acute Hospital Care at Home waiver for five full years through 2030. [4] The era of 90-day extensions and policy uncertainty is, at least for now, over.

Who Is Actually Running These Programs Today?

The list reads like a who’s who of American medicine:

Advocate Health launched its HaH program as a 10-day sprint at the start of the COVID-19 pandemic and has since expanded to 12 facilities across two metropolitan areas, serving more than 16,500 patients and avoiding more than 60,000 inpatient bed days. [5]

Cleveland Clinic implemented Hospital Care at Home at its Florida locations in 2023 and has since helped more than 4,000 patients heal and recover at home. The program is built around a proprietary Clinically Integrated Virtual Command Center (CIViC), which monitors patients around the clock and connects them to their care team at the push of a button. In 2026, Cleveland Clinic expanded the program to Northeast Ohio. [6a]

Virtua Health in southern New Jersey launched its HaH program in January 2022 and has enrolled more than 900 patients across 60-plus distinct medical conditions, operating across all five of its South Jersey hospitals from a centralized command center in Pennsauken. [6b]

In 2025 alone, four additional health systems launched new HaH programs: NewYork-Presbyterian, Nemours Children’s Health (described as the nation’s first at-home acute care model run by a freestanding children’s hospital), Valley Health System in New Jersey, and St. Luke’s Health System in Boise, Idaho. [7]

Tampa General Hospital launched its HaH program in Citrus County, Florida in March 2026, combining remote patient monitoring and telehealth visits with in-person care. [8]

This is not a pilot. This is not a concept paper. This is operational medicine, functioning across dozens of major health systems, serving tens of thousands of patients, right now.

The Outcomes Data — What Does the Evidence Actually Show?

For any physician reading this, the clinical question comes first: does it work? Is it safe? What happens when a patient deteriorates at home?

The evidence has now reached a level of consistency that makes those questions answerable.

On Readmissions

Mass General Brigham’s randomized controlled trial found a 7% 30-day readmission rate for HaH patients versus 23% for traditional inpatient care, with zero inappropriate medication errors and fewer safety events. [5] At the program level, patients enrolled in MGB’s HaH program had 30-day readmission rates of 9.2% in fiscal year 2025, compared to 16% for patients in traditional inpatient settings. [3]

On Mortality

Medicare beneficiaries who received care under the AHCAH initiative generally had a lower 30-day mortality rate compared to individuals who received inpatient care in traditional hospital settings, according to a 2024 CMS report. [3] A 2024 study published in BMC Health Services Research reported an in-episode mortality rate of 0.32% and a 30-day mortality rate of 4.35%, both comparable to conventional care. [9]

On Clinical Complications

Hospital-at-Home has been associated with a 74% reduction in delirium risk and lower rates of certain clinical complications. [10] This finding deserves significant attention — delirium in hospitalized elderly patients is a major driver of functional decline, extended stays, and nursing home placement.

On Cost

Researchers testing the model at Medicare managed care sites reported cost savings of approximately 30% compared with traditional inpatient care, along with better clinical outcomes, lower average length of stay, and fewer lab and diagnostic tests. [11] Johns Hopkins reports savings of 19% to 30% compared with in-hospital care across its program data. [11]

On Patient Experience

As of fiscal year 2025, HaH programs have resulted in 95% of patients rating the service a 9 or 10 out of 10 when asked whether they would recommend it to others. [3] Mass General Brigham’s Net Promoter Score for its HaH program has surpassed Apple’s. [5]

What Conditions Are Being Treated?

Current HaH programs have demonstrated safety and efficacy for pneumonia, heart failure exacerbations, COPD, cellulitis, post-surgical recovery, and increasingly, complex oncology patients. Tampa General’s CEO John Couris reported that the program is treating transplant patients and getting them home a week earlier than traditional admission, and caring for complex oncology patients in the comfort of their own homes. [12]

The clinical picture is clear: for appropriately selected patients, HaH is not a compromise. It is, by most measures, a superior care setting.

The $1.6 Trillion Context — Why This Matters at a Systems Level

To understand why HaH is attracting serious attention from health systems, payers, policymakers, and entrepreneurs, you need to understand the financial scale of what it’s challenging.

Hospital spending represented close to a third — 31% — of overall U.S. health spending in 2024. [13] In concrete terms, hospital care hit $1.6 trillion in 2024, with spending rising 8.9% over the prior year. [14]

Between 2022 and 2024, hospital care alone accounted for $277 billion of the $692 billion total growth in national health expenditures — 40% of the entire increase in national health spending. [15] CMS projects that hospital spending will rise to 6.4% of GDP by 2033. [15]

For patients, these numbers translate directly into affordability crises — higher premiums, larger deductibles, and medical debt. For health systems, they represent crushing operational pressure. For payers and employers, they represent an unsustainable cost curve. And for entrepreneurs and healthcare innovators, they represent a massive, structurally vulnerable cost center that is increasingly open to disruption.

McKinsey & Company has estimated that as much as $265 billion worth of care services — up to 25% of the total cost of care for Medicare beneficiaries — could shift from traditional facilities to the home without a reduction in quality or access. [11]

Where Concierge Medicine, Executive Health, and DPC Fit — Honestly

This section deserves its own honest framing upfront: Hospital-at-Home is not concierge medicine. It is not a membership medicine model. It does not replace what concierge, executive health, or direct primary care physicians do, and it should not be positioned that way.

But the overlap is real, specific, and clinically meaningful — and physicians in this space would be making a strategic mistake to ignore it.

The Concierge Physician as the Ideal HaH Clinical Partner

HaH programs live or die on patient selection. The clinical team running a home-based acute care episode needs to know, in advance, whether a patient’s home environment is safe, whether family or caregiver support exists, what the patient’s baseline functional status looks like, what medications they’re actually taking versus what’s on the chart, and whether the patient has the health literacy and temperament to participate actively in their own monitoring.

A concierge physician already knows all of that.

The typical concierge physician has a panel of 300 to 600 patients, sees them regularly, often knows their families, and maintains the kind of longitudinal relationship that a 5,000-patient primary care practice structurally cannot support. That relationship intelligence is precisely what HaH programs lack when sourcing patients from emergency departments or inpatient referrals from physicians who barely know the patient.

There is a legitimate and underexplored opportunity for concierge practices to formalize referral relationships or care coordination agreements with HaH operators or health systems running HaH programs in their markets. The concierge physician becomes the trusted clinical anchor — the person who knows the patient well enough to say with confidence: this patient is appropriate for home-based acute care, and here is why.

Direct primary care physicians share this same relationship-driven foundation and the same intimate patient knowledge — and while the formal care coordination infrastructure of a HaH partnership may be a heavier operational lift for smaller DPC practices, the underlying patient selection and advocacy role remains equally relevant.

That is not a small role. It is a clinically essential one.

Executive Health Programs

The connection here is even more direct. Executive health programs serve a patient population that has, almost by definition, the home environment, the caregiver support structure, and the strong preference for avoiding institutional settings that make HaH viable. High-net-worth patients who invest in executive health programs are precisely the patients who will ask — when they or a family member face an acute illness — whether hospitalization is truly necessary or whether equivalent care can be delivered at home.

Executive health physicians who are not yet familiar with HaH are going to start fielding this question from their patients. Being prepared to answer it — knowing which local health systems operate approved programs, understanding the eligibility criteria, and being able to facilitate that conversation — is a practical, near-term clinical competency for this segment of the market.

Where the Connection Does Not Hold — And Why That Matters

Long-term care management and hospice both share the philosophical premise that home is often the right setting for care. But the clinical intent of HaH is fundamentally different from both.

HaH is acute, curative, time-limited care — typically three to five days — for a patient who is medically stable enough to be managed outside a hospital building but sick enough to require hospital-level intervention. It is not chronic disease management. It is not end-of-life care. Conflating these models, even loosely, would introduce clinical confusion that serves no one.

The honest editorial position is this: concierge and executive health physicians have a specific, credible, and clinically grounded role in the HaH ecosystem — not as operators of HaH programs, but as the relationship-based primary care partners who make those programs safer, more effective, and better matched to the right patients. That is a role worth claiming.

The Disruption Argument — Why HaH Is a Genuine Threat to Expensive Hospitals

This section is an educational, analytical framework. It does not constitute business, legal, financial, or investment advice. Readers considering any healthcare venture should consult appropriate licensed advisors.

For the first time in the history of American healthcare, a credible, federally authorized, outcomes-proven model exists to deliver a meaningful portion of inpatient care outside hospital walls — at 20 to 40 percent lower cost, with better results.

Hospital spending hit $1.6 trillion in 2024. It is the single largest cost center in American healthcare — nearly a third of every dollar spent. And for the first time, a model exists that can credibly challenge it at scale.

That is not incremental improvement. That is structural disruption.

The global Hospital-at-Home market is projected to grow from $37.17 billion in 2025 to $72.84 billion by 2034 — nearly doubling in under a decade. [17] Atrium Health projects that its HaH program will free up 10% of its inpatient hospital beds. [11] When a major health system removes 10% of its inpatient bed demand through home-based care, that is not an operational tweak. That is a fundamental reallocation of where acute care happens — and who captures the revenue from it.

Traditional hospital care, with its associated overheads — infrastructure, 24/7 staffing, inpatient services — is structurally expensive in ways that home-based care is not. HaH programs eliminate expenses tied to hospital facilities while delivering comparable or superior clinical outcomes. [18] The fixed-cost burden that makes hospitals expensive is precisely what HaH sidesteps.

The five-year federal waiver extension has now removed the single biggest barrier to investment. Health systems had been waiting on the sidelines, hesitant to commit without policy certainty. That certainty now exists. [12] Up to 40% of hospital system leaders are either already executing or actively planning a hospital-at-home strategy. [16]

What a Disruption Business Actually Looks Like

The most strategically coherent vehicle for disrupting expensive inpatient care is a third-party HaH operator — a company that builds the clinical protocols, technology infrastructure, care coordination systems, and logistics networks, then partners with hospitals, Medicare Advantage plans, self-insured employers, and commercial insurers to deploy at scale.

This is not a theoretical model. Companies including Medically Home, DispatchHealth, and Contessa have all built working versions of it. That said, following its merger with Medically Home, DispatchHealth restructured its operations in September 2025 — exiting one market and scaling back services in nine others including Atlanta, Dallas/Fort Worth, Los Angeles, and Seattle. [6c] The lesson is not that the model fails. The lesson is that execution risk is real, and capital efficiency and patient volume ramp-time are underestimated by most entrants.

The defensible competitive asset in this business is the technology platform: AI-assisted patient eligibility screening, real-time vital sign monitoring, predictive deterioration analytics, and seamless EHR integration. Without that infrastructure, a third-party operator is simply a staffing agency. With it, the operator becomes structurally difficult to displace.

The Three Honest Risks

Reimbursement risk, while significantly reduced by the five-year extension, has not been eliminated. Policy can always change. Payer diversification — through Medicare Advantage and self-insured employer contracts — is not optional. It is structural protection.

Patient selection is a clinical and operational risk. HaH is not appropriate for all acute presentations. Programs that have failed operationally have typically underinvested in eligibility infrastructure and escalation protocols.

Scale economics are demanding. The model works at volume. It struggles in low-census markets. Geographic expansion strategy and payer contract sequencing are the two most consequential early decisions an operator will make.

Workforce satisfaction, notably, has been a consistent positive surprise. Staff working in HaH programs consistently report high satisfaction — often describing it as allowing them to practice the medicine they trained to deliver. [12]

What This Means for Independent Physicians — The Strategic Lens

HaH is not a story about technology. It is a story about care setting, physician judgment, and the relationship between patient experience and outcomes. That argument will sound immediately familiar to any physician practicing concierge or direct primary care medicine.

Mass General Brigham’s president of Healthcare at Home has framed it simply: home is the best site of care whenever possible — not just for comfort, but for quality and equitable health outcomes. The results are consistent across programs: lower readmission rates, increased mobility, lower mortality, increased patient satisfaction, and increased workforce satisfaction. [16]

The parallel to what CMT has long argued about concierge and membership medicine is not subtle. When you reduce panel size, you increase relationship depth. When you increase relationship depth, you improve continuity of care. When you improve continuity of care, you catch problems earlier, reduce unnecessary utilization, and produce better outcomes at lower cost. HaH is making an almost identical argument at the acute care level — and the data is now robust enough that major health systems and federal policymakers are acting on it.

At least 10% of patients being treated in brick-and-mortar hospitals around the nation could be treated in home hospital programs, according to clinical leaders actively running these programs. [16] That is not a marginal number. It is a structural shift.

Independent physicians who understand this trend — and who can position their practices to complement or partner with evolving acute care delivery models — will be better prepared for what comes next. The concierge physician who already knows a patient’s home situation, family support system, and baseline functional status is, in many ways, the ideal clinical partner for a HaH program.

That conversation is only beginning.
