Introduction
“If you build it, they will come.” In the movie “Field of Dreams,” that phrase captured the expansive opportunity to attract people from far and wide simply by building an edifice in an unlikely, remote place. In the movie, the edifice in question was a primitive baseball stadium in an Iowa cornfield that would serve as an attraction for players and fans. But that phrase, and the promise behind it, also applies in other contexts — notably in American health care. In the health care context, the phrase encapsulates the trajectory of the industry over the past 75 years, with “you” being the federal government and “they” being the private health care industry. Over that time, the system has grown through an array of government funding and regulatory programs that created the field on which private entities, both domestic and foreign, have played the game of American health care business.
The government’s playing field and the private businesses it has attracted have nurtured health care as an ever-expanding, ever-more expensive public-private partnership. The result is a health care system that is more complex and costly than any other in the world.Footnote 1 It is also a system that is extremely profitable for those who come to play. Health care was a $4.9 trillion industry in 2023,Footnote 2 with the private sector estimated to account for about 30% of it.Footnote 3 The health care industry which has developed over the past century now includes thousands of businesses serving millions of patients,Footnote 4 with each business seeking the opportunity to share in the industry’s profits.
Many, although certainly not all, of the businesses are excellent players, enhancing the health of untold numbers of patients and giving the government substantial returns on its investments. However, even well-meaning players in the industry must navigate a bewildering maze of laws, regulations, and policies to enter and stay in the playing field. Health law has grown with the system as a critical component to guide private businesses and government policymakers.
Unfortunately, this complex playing field often, and with increasing frequency, gives those who are not good players the chance to undermine the system. This is seen, for example, in billing fraud under government health insurance programs, incentives for providers to favor wealthier and better-insured patients, commercialization of industry segments leading to market consolidation and higher prices, and corporatization of key provider sectors by private equity, which studies indicate can lead to poorer patient care.Footnote 5 With regard to these businesses, the role of lawyers is especially critical in helping health care entities understand what the bounds of the law are and, often, where they can bend. Thus, the development and expansion of the field of health law is a key byproduct of the health care system’s evolution. On this field of dreams, games cannot be played without team owners to write the rules, coaches to teach them, and umpires to enforce them.
This article describes key developments in the evolution of American health care’s public-private partnership, the benefits and harms brought by these developments, and the increasingly central role of health lawyers. The public-private partnership has created an industrial juggernaut.Footnote 6 In 2023, it represented more than one-sixth of the country’s economy.Footnote 7 The range of enterprises it encompasses includes providers (both institutional and individual), insurers that finance provider services, and a host of ancillary health care businesses. As a result of the government support needed to sustain and oversee this growth, health care spending now devours the largest share of federal spending, eclipsing even the defense sector.Footnote 8
I. Origins and “Ancient” History
To understand any business, it is necessary to follow the money and see the forces that shape its incentives. In health care, most of that money comes from insurance, both public and private.Footnote 9 Therefore, we begin our analysis with the origins of that financing mechanism.
A. Private Health Insurance: Emergence and Regulation
Health insurance in the United States emerged in its present form in 1929, when Baylor University Hospital in Texas established the first Blue Cross plan to cover hospital costs.Footnote 10 As similar plans were created in other parts of the country, Blue Cross’s network grew state-by-state throughout the Depression era and during World War II.Footnote 11 The first Blue Shield plan was created in 1939 to cover the costs of physician care.Footnote 12 It developed alongside the expanding array of Blue Cross plans to offer comprehensive coverage for medical expenses. The two plans were formally combined as the Blue Cross/Blue Shield Association in 1982.Footnote 13 Both plans were committed to a nonprofit structure and to “community rating”, meaning that all individuals and companies enrolled in a plan were placed in the same risk pool and charged the same premium regardless of their individual or group loss experience.Footnote 14 This practice distinguished these plans from those of private commercial plans, which actuarially rated individuals and groups they covered and charged them different premiums based on their risk characteristics.Footnote 15
For almost half a century, the regulatory structure that oversaw health insurance was based on the Supreme Court’s 1869 decision in Paul v. Virginia,Footnote 16 which ruled that insurance was not “interstate commerce” and, thus, not subject to federal regulation.Footnote 17 As a consequence of that ruling, insurance regulation evolved at the state level, with each state administering its own regulatory apparatus.Footnote 18 Over time, the state insurance regulators joined together to create the National Association of Insurance Commissioners (“NAIC”).Footnote 19 When, in 1944, the Court overturned Paul in U.S. v. Southeastern Underwriters Association,Footnote 20 the NAIC led a campaign to preserve state control over insurance, resulting in the 1945 passage of the McCarran-Ferguson Act.Footnote 21 Under that law, authority to regulate health care was returned to the states. However, over subsequent decades, the federal government reasserted its authority in other aspects of the industry, eclipsing the states as the primary locus of oversight and policymaking in many respects.Footnote 22 The result was a patchwork arrangement of state regulation, federal regulation, and business expansion.
B. Private Health Insurance: The Foundation of Subsequent Government Financing
As discussed below, government programs to expand access to health care, such as Medicare and Medicaid, built upon the foundation of private financing rather than replacing it. The result is a hybrid structure like that overseeing private health insurance. This structure sees federal and state authorities cooperating to provide financing and oversight, while private entities provide much of the service and administration. Those private entities include Blue Cross/Blue Shield and a large number of commercial insurance companies.
To put this government insurance structure in historical context, it is helpful to understand the two prevailing national health care models that the United States could have followed. Under the Bismarckian approach — named after Otto Von Bismarck, Chancellor of the German Reich from 1871 to 1890 — the government requires private employers to provide health services for their employees and often for their family members as well.Footnote 23 The underlying notion is that, in an effectively functioning society, employers and their employees form a core part of the economy, and therefore the government can use the employment structure to ensure that all — or, at least, most — citizens have a required minimum level of coverage. Under the Beveridge approach — promoted by Lord William Beveridge, who served in Parliament from 1944 to 1945 and helped form the basis of the British National Health Service — the national government both regulates and provides health services through its own employees and facilities.Footnote 24
II. America’s Path Toward More Universal Health Care: The Long and Winding Road With Bumps and Detours
A. Truman Gets the Ball Rolling
The path toward broader, if not universal, coverage is strewn with a collection of programs based on the public-private partnership model. This path began in 1946, when Congress passed the Hill-Burton Act, an initiative of President Harry Truman that implemented the first major federal health care funding program.Footnote 25 Unable to get a national health insurance plan through Congress, Truman accepted Hill-Burton as a “consolation prize” that would help private hospitals across the country build, expand, and modernize their facilities in order to serve more patients.Footnote 26 In so doing, the federal government would correct for serious underinvestment in the health care system during the Depression and World War II.
Hill-Burton also addressed financial barriers to accessing care, although its funding for services has been inconsistent over the years.Footnote 27 Moreover, in return for the chance to dip into the law’s six billion dollar pot of grants and loans, hospitals were required to comply with a set of regulations related to access, including nondiscrimination rules, which represented the first direct federal oversight of the industry.Footnote 28 With that platform of funding and regulation, the modern hospital system was born.
B. Medicare and Medicaid and a Federal “Blank Check” to the Health Care Industry
Truman’s vision came closer to realization two decades later with the creation of Medicare and Medicaid in 1965. Although preceded by some less-ambitious initiatives,Footnote 29 these were the first major federal programs to broadly address financial barriers to care.Footnote 30 While Truman’s goal of universal coverage was not achieved, coverage was guaranteed for some groups, namely the elderly, disabled, and some categories of the poor.Footnote 31 Medicaid, passed into law in 1965 along with Medicare, relies on a federal-state partnership model which uses a “carrot and stick” approach, combining incentives for participating and disincentives for abstaining. Under Medicaid, the federal government offers money to help states finance health care for the poor if they meet and adhere to federal program standards.Footnote 32 Medicare, by contrast, is a unified federal program, originally administered by the Social Security Administration.Footnote 33 Even with this structure, though, Medicare has a strong private sector component, in which the administration of claims is carried out to a large extent through private companies under contract with the federal government.Footnote 34
A revealing footnote to the birth of Medicare is that the legislative proposal was hurriedly penned in July of 1965 by Wilbur Cohen, Secretary of the Department of Health, Education and Welfare, and one of his chief aides, William Kissick.Footnote 35 The Cohen-Kissick draft, which formed the core of the Social Security Amendments of 1965 that established the program, was written in response to a Thursday afternoon call from President Lyndon Johnson, who had arranged for a Congressional sponsor to introduce the bill the following Monday and needed a proposal as soon as possible.Footnote 36 Blue Cross and Blue Shield were used as the template because their networks accounted for more than fifty percent of the health insurance market in the United States.Footnote 37 The premise behind doing so was that the federal government would simply pick up the tab for that predominant form of coverage for the nation’s elderly and disabled — a private template for federal infrastructure.
This approach was born out of political necessity, as the American Medical Association, along with other prominent health care organizations, had long waged a vigorous fight against what they termed “socialized medicine,” meaning government influence over the health care system.Footnote 38 This accounts for the stark language of the opening section of the Medicare law, which forbids federal employees and officers from controlling or interfering with the practice of medicine.Footnote 39 The law also avoided all but minimal consideration of cost control.Footnote 40 That situation changed markedly over subsequent decades.
An important and sometimes overlooked aspect of Medicare and Medicaid is the extent to which they were designed not to operate independently of the private sector. Despite the frequent mischaracterization of Medicare as a national “single payer” program, the government has built a structure in which private companies can and do play a prominent role.Footnote 41 Private hospitals and physicians, not government providers, continue to render care, and financing remains a shared responsibility. Private insurance companies continue to sell policies supplementing Medicare, in addition to administering claims through subsidiaries in each state.
The federal government’s role in overseeing this complex arrangement fell to an expanding bureaucracy. Although Section 1801, forbidding federal control of medical practice,Footnote 42 remains in the statute, it became increasingly clear that some degree of oversight and cost control was needed. As discussed below, Congress passed a package of Medicare amendments in 1972, enabling the Social Security Administration to take the lead in administering new regulations. By 1977, the regulatory demands had grown so complex that a separate agency was needed, and so the Health Care Financing Administration (“HCFA”) was created. With the addition of Medicare Advantage under Part C of the program, along with prescription drug coverage under Part D in 2003 (enacted as part of the Medicare Modernization Act), the agency’s role grew again, and it was given a new name, the Centers for Medicare & Medicaid Services (“CMS”).Footnote 43
Health care providers, insurance companies, and consumers had to keep up with this growing maze of bureaucracy. In response, health law as a distinct field grew in prominence, and, beginning in the 1970s, legal professionals and scholars formed a number of academic and professional organizations focusing on health law and policy. Notable organizations included the American Health Law Association (“AHLA”), the American College of Legal Medicine, and the American Society of Law and Medicine (“ASLM”), now known as the American Society of Law, Medicine and Ethics (“ASLME”).Footnote 44
C. The First Major Medicare Amendments in 1972
As Cohen and Kissick had anticipated, the inauguration of Medicare and Medicaid greatly increased the demand for health care services and the country’s total expenditures on such services.Footnote 45 Leaving it to physicians to determine the need for health services on a case-by-case basis, consistent with the Blue Cross model, made the early Medicare structure the very antithesis of cost containment. With the government standing by as a generous payor, hospitals and the doctors practicing in them had a substantial incentive to keep patients in the hospital longer to generate more revenue for the institution. As UCLA Professor Milton Roemer famously observed with regard to hospitals in 1968, “a bed built is a bed filled” under fee-for-service payment.Footnote 46 Recognition of this cost-increasing effect came to be known as “Roemer’s Law.”Footnote 47
Clearly something had to be done. A first step was to control the overbuilding of hospital beds. Doing this required consensus standards for how long a patient should stay in the hospital for a particular condition. This was addressed through Certificate of Need (“CON”) laws in a number of states and, ultimately, the passage of the federal National Health Planning and Resources Development Act, which divided the country into Health Service Areas (“HSAs”).Footnote 48 Under CON laws, hospitals wishing to expand their facilities had to show statistically that this expansion was actually needed — in other words, new government oversight in return for the continued flow of government dollars.
However, another step was needed for the physician side to control excessive lengths of stay during which an admitting physician could order and bill for the services they rendered in the hospital. This was addressed through the 1972 amendments by creating a nationwide network of Professional Standards Review Organizations (“PSROs”), regional organizations that mobilized the medical community to articulate and enforce standards regarding the medical necessity and reasonableness of services delivered and paid for through Medicare.Footnote 49 Those standards were then used to monitor physician patterns of utilizing services and resources. Even with the intervention of PSROs, however, there remained a substantial variety of ways to treat a patient identified as suffering from a given medical condition, some more expensive than others. PSROs were a far cry from an enforceable uniform national standard.
As Roemer’s law applies mainly to fee-for-service reimbursement, in which each service rendered generates revenue for the provider, policymakers began to realize that this kind of reimbursement was at the heart of run-away costs. This led to an effort to switch payment under Medicare and Medicaid to a “prospective payment” model, under which reimbursement is paid based on a patient’s condition rather than the number of services rendered to treat it. This led to a move to pay hospitals for inpatient stays on the basis of Diagnosis-Related Groups (“DRGs”), sets of diagnoses that required similar sets of services.Footnote 50 Under this approach, statistics are developed on the set of services that hospitals provide, including the number of days of hospitalization customarily used to treat a particular diagnosis.Footnote 51 If attending physicians feel that a patient’s situation justifies deviating from the standard package, it is incumbent on them to marshal the evidence to prove the need for extra payment. The DRG approach was first tried as a state-wide experiment under New Jersey’s hospital rate-setting system in 1980 and then extended to Medicare in 1983.Footnote 52 Nevertheless, while the government changed the rules of reimbursement, hospitals continued to find new ways to play and win at the game of revenue generation.Footnote 53
III. Broader Federal Infrastructure and the Birth of Managed Care
A. The Managed Care Movement
The prospective payment concept revolutionized not just Medicare and Medicaid, but also American health care more generally. Its most basic form is the Health Maintenance Organization (“HMO”), a health care delivery system developed by Dr. Paul Ellwood at Interstudy, a Minneapolis-based health policy think tank he founded and directed.Footnote 54 In HMO plans, patients are assigned a designated primary care physician who directs all their care, subject to oversight by the plan.Footnote 55 In 1973, the federal HMO Act was passed, offering subsidies to fund the startup and initial operation of nonprofit HMOs and mandating that larger employers who provide health insurance to their employees offer an HMO or “dual choice” alternative.Footnote 56 As the HMO movement took off, HMOs evolved in two main forms. Prepaid Group Practices (“PGPs”), follow the model of Kaiser-Permanente in which the plan directly employs physicians and owns its own hospitals.Footnote 57 The other form, Individual Practice Associations (“IPAs”), use networks of private independent practices.Footnote 58 Over time, more variants emerged, including Preferred Provider Organizations (“PPOs”), and a more inclusive term, Managed Care Organizations (“MCOs”), was applied to cover all of them.Footnote 59 In the early 1980s, an increasing number of HMOs switched from nonprofit to for-profit status, and the for-profit structure soon came to dominate the market.Footnote 60
Subsequent decades saw HMOs evolve into yet another private health care sector founded and shaped by federal policies. They grew from a humble beginning where they needed a federal push to get off the ground into the predominant form of private health insurance in the United States. From 1976, three years after the Act was passed, until 1987, the number of plans increased from 175 to 650, and the number of enrolled members increased from six million to 29.3 million.Footnote 61
HMOs also received an unexpected boost from the Employee Retirement Income Security Act of 1974 (“ERISA”), a Byzantine law that eased the path to self-insurance for large employers.Footnote 62 Under that law, many of those companies could choose to cover their employees’ health care costs themselves without going through an insurance company, and many chose to do so by contracting with MCOs.Footnote 63 This meant that companies could save on administrative costs by cutting out insurance companies as middlemen and offer managed care plans to their workers as a cost-saving, at least in theory, approach to coverage. Along with self-insurance under ERISA came a new health care regulatory player, the Department of Labor (“DOL”),Footnote 64 expanding the overall health care regulatory playing field.
Dominating the private insurance market was just the start. In 1997, MCOs received another boost from federal policy when Medicare added Part C (now known as Medicare Advantage) as an option for beneficiaries to replace traditional coverage with a private managed care plan.Footnote 65 In 2006, Medicare Part D, which uses private plans to provide prescription drug coverage, took effect.Footnote 66 State policy also provided a major boost. Starting in the 1980s, several states began to administer Medicaid through private managed care plans, and today all states do so to at least some extent.Footnote 67 In 2016, Medicare and Medicaid accounted for $213.1 million, or 59%, of revenue from premiums and administrative-services-only contracts across the five largest health insurance companies.Footnote 68
B. Expanding Access Through the Affordable Care Act
In 2010, the most complex federal health care infrastructure program of all was created by the Patient Protection and Affordable Care Act, more commonly known as the Affordable Care Act (“ACA”) and often referred to as “Obamacare.”Footnote 69 It expanded coverage in two main ways. First, it created online exchanges through which Americans could purchase individual coverage without regard to preexisting medical conditions and with subsidies for those with lower incomes.Footnote 70 Second, it offered states a financial incentive to expand their Medicaid programs to cover more people.Footnote 71
Both of these measures gave the private sector huge new opportunities. The exchanges create a market for private individual insurance with millions of new customers, while the expansion of Medicaid means a larger role for MCOs that administer plans on behalf of states.Footnote 72 The greater number of insured individuals, in turn, generated more patient demand for the services of hospitals and other providers to the point where many institutions depend on Medicaid and other government subsidies for their very financial survival.Footnote 73 These measures also vastly expanded the role and responsibilities of CMS, not to mention the demand for lawyers to work in it, with it, and against it.Footnote 74 Despite numerous attempts to repeal it, the ACA is now more than fourteen years old, stable, and continuing to move the United States closer to its ideal of universal health coverage.Footnote 75
IV. Private Health Care Grows from Government Sidekick to Big Business
A. For-Profit Proliferation
Beyond insurance companies, a range of private players — including hospitals, physicians, and nursing homes — have built a web of profitable initiatives on the government’s playing field. Investors regularly demonstrate their awareness of this interdependence between private players and government support. Notably, the stock prices of publicly traded health care companies, which reflect expectations of future profits, often rise and fall alongside Medicaid enrollment.Footnote 76 In fact, during the COVID-19 pandemic, one of the best predictors of a hospital’s financial resilience was its home state’s decision to join the ACA Medicaid expansion.Footnote 77 Moreover, for-profit entities throughout the industry have come to rely on a wide range of government subsidies — from temporary support under the CARES Act passed in the early stages of the COVID-19 pandemic to various tax breaks to Medicare and Medicaid reimbursement — without a requirement to provide charity care or other public services commensurate with the public support they receive.Footnote 78
More than simply helping a subset of players in the health care industry, government support has fueled a broader corporatization of health care by freeing capital for mergers and acquisitions that have consolidated providers and reduced competition in many local markets across the country. In 2005, only 53% of hospitals belonged to a larger system.Footnote 79 By 2017, those systems accounted for 66% of all hospitals.Footnote 80 This consolidation often empowers systems to act monopolistically, restricting access to health care and driving up the prices that consumers pay.Footnote 81 There has also been substantial vertical integration among health care systems, allowing hospitals to refer their patients to more expensive physicians within the same system.Footnote 82 When a system’s market share becomes large enough, it can also gain monopsonistic power over labor markets in which physicians seek employment.Footnote 83
In concentrated markets, physicians’ satisfaction with their jobs tends to decline, as health system employers and insurance companies often force them to spend less time with each patient, generating more stress for the physician and worse outcomes for the patient.Footnote 84 The same trend has been found in hospice care, where for-profit institutions cut costs to boost their bottom line and therefore score significantly lower on patient satisfaction measures.Footnote 85 For-profit entities are also more likely to shift their treatment mix to emphasize more profitable procedures. When these hospitals experience financial losses, the incentive to do so is even greater, often to the neglect of other treatments their patients may need.Footnote 86
B. The Growing Role of Private Equity in Health Care
Corporate health care has proven so profitable that it has drawn new investors from outside the industry. Large institutional investors, such as pension funds and university endowments, are always looking for new industries in which to invest, but they do not typically possess the internal expertise or management capacity to play a controlling role in health care firms.Footnote 87 This has created an opportunity for private equity funds — insular, non-public funds which pool investments from wealthy, sophisticated investors in order to acquire entities — to seek to fundamentally restructure these firms with the goals of realizing short-term profits and outsized returns for their investors.Footnote 88 They have channeled large amounts of institutional capital into the health care industry, with fund managers taking on the task of restructuring the target firms.Footnote 89
Contrary to the private equity sector’s claims, these firms are rarely in the business of saving health care entities from financial distress. Research has shown that private equity investors more often target hospitals with better financial performance that are not in need of rescue.Footnote 90 Rather than trying to improve performance, the new owners often break acquired hospitals into pieces, strip assets from them, and sell the pieces to separate owners, under the theory that the market will pay more for them if they are put to a different use.Footnote 91 An especially profitable piece is often the facility’s real estate, which may have value for a range of different businesses. The net effect is often to take much of the hospital industry, and other institutional providers such as nursing homes, out of the business of serving their patients.
This process often hollows out the facilities so significantly that they have no choice but to file for bankruptcy.Footnote 92 This outcome may seem like a failure, but private equity firms often do not count on the success of a provider to generate their returns. Instead, they have often siphoned off the profitable assets, allowing them to walk away without incurring much cost and with a strong short-term return on their investment.Footnote 93 The ironic upshot of this scheme is that the government’s health care infrastructure has been used to diminish, rather than enhance, the country’s health care capacity.
For the providers that survive private equity takeovers, the delivery of health care can change dramatically. This results from three strategies private equity owners use to generate high returns. First, they cut costs, typically by reducing staffing levels and dispensing with costly safety protocols. Patients have been found to experience a twenty-five percent increase in adverse events as a result.Footnote 94 Second, they minimize the treatment of low-income patients, focusing instead on more profitable customers.Footnote 95 Third, they “roll up” physician practices, creating market power by bringing many smaller entities that had been competitors under one umbrella.Footnote 96 This consolidation allows them to charge higher prices, which then leads insurance companies to charge higher premiums.Footnote 97 Research has found that higher insurance costs can create severe financial strain for small companies, and, in some instances, cause them to discontinue contributing to employee health insurance premiums altogether.Footnote 98
Yet, with all of this corporate activity, “private” equity may be a misnomer. The companies may not be publicly traded or publicly owned, but they rely heavily on public subsidies. Many of their largest investors, including public pension funds and university endowments, enjoy large tax breaks because they theoretically serve a public purpose.Footnote 99 Their acquired providers, including hospitals and physician practices, receive reimbursement from private health insurance that is publicly subsidized through its tax treatment or from government programs, such as Medicare and Medicaid. Even the private equity fund managers themselves pay lower taxes than employees of other firms, as investment activities are taxed at a lower rate than wages.Footnote 100 At the same time, many patients still pay higher prices that the acquired entities charge.Footnote 101
V. The Playing Field for Health Care Products
A. Drugs and Devices
While the provider and finance sides of health care were coming in waves to play in the government’s field of dreams, the pharmaceutical industry was playing just as aggressively. After World War II, the National Institutes of Health (“NIH”) became indispensable to financial support for the basic biomedical research that forms the backbone of new drug development.Footnote 102 On top of that, the Human Genome Project (“HGP”), launched in 1990, led to a new era in therapeutics in the form of genomic medicine and precision medicine, through which drugs and treatment modalities are tailored to an individual patient’s genetic makeup.Footnote 103 As American medicine’s pharmacopeia has grown, intellectual property protection for the industry’s products has become an ever more pressing concern — and with it, the role of the federal Patent and Trademark Office, which decides which products deserve protection from competition.Footnote 104 Further, the widening scope of pharmaceutical interventions has imposed larger and more complex responsibilities on the Food and Drug Administration (“FDA”) in overseeing the testing, use, and marketing of new drugs and devices.Footnote 105
B. Health Technology
1. Mobile Health
Alongside the government’s investments in pharmaceuticals over the past seventy-five years, its investments in technology have generated a revolution in our society, a revolution now reaching into every facet of health care. The computer, the cell phone, and all of Silicon Valley’s other products and services would not exist in their current advanced state without large, early inflows of tax dollars.Footnote 106 Most of our digital and mobile technologies began in government-funded basic research laboratories and grew into profitable enterprises thanks to the government’s role as one of the first and largest purchasers of these technologies.Footnote 107 It was only a matter of time before these for-profit enterprises figured out how to use the same digital and mobile technologies to deliver and finance heath care.
Today, health care consumers can open their phone and find thousands of health-related apps to download.Footnote 108 They can order at-home tests for everything from COVID-19 to cholesterol to food sensitivity to fertility to sleep apnea.Footnote 109 They can track their heart rate, respiratory rate, skin temperature, blood pressure, and even their glucose levels with watches, cell phones, and other wearable devices.Footnote 110 They can even scan their own brain activity with at-home electroencephalogram headsets.Footnote 111 Some of these devices are regulated by the FDA. Many are not. Few are used with the supervision of a medical professional.Footnote 112
Even medical professionals are taking advantage of the convenience and time savings afforded by digital health care delivery. “Telehealth” (or “telemedicine”) has been growing for decades, first with phone call appointments and now with video calls. The use of telehealth further accelerated during the COVID-19 pandemic because it allowed patients and physicians to connect at a distance.Footnote 113 The measured impact on patient health has been mostly positive. Access to telehealth is associated with fewer emergency room visits and better adherence to medication regimens.Footnote 114 Patients are only slightly more likely to return for an in-person follow-up visit after a telemedicine appointment, compared to an initial in-person visit.Footnote 115 However, many outcomes remain unmeasured, many populations remain underserved, and the telehealth profit motive often crowds out other services that cannot be delivered digitally. It remains to be seen whether this technology will disrupt more than it improves health care.Footnote 116 In either event, this telehealth revolution represents another innovation generated by collaboration between government infrastructure and private sector initiative.
Health law has struggled to keep up with these fast-and-furious developments. The FDA has shied away from defining most at-home technologies as “medical devices,” and Congress has signaled its support for this hands-off approach.Footnote 117 Therefore, as a growing share of health care is delivered outside of the traditional medical facility setting, patients will find that their health care is increasingly unregulated — and their privacy, safety, health, and civil rights are increasingly unprotected.Footnote 118 This creates a gap yearning for a new kind of health law to fill.
2. Artificial Intelligence
Nowhere is the technological frontier expanding more rapidly than in the use of artificial intelligence (“AI”). In clinical settings, evidence has already shown that AI can often diagnose diseases more accurately and prescribe treatments more effectively than human physicians.Footnote 119 In the laboratory setting, researchers are finding that AI can process large datasets, sequence genomes, find useful connections and correlations, and identify “precision medicine” treatments targeted to specific individuals far more quickly and accurately than previous statistical models.Footnote 120 AI care managers are even being employed in place of nurses and physician assistants to deal with patients by phone or video conferencing, for example, in routine follow-up care.Footnote 121 We are only beginning to understand how these advances will transform almost every aspect of the industry.
At the same time, AI presents a range of new challenges for lawyers, regulators, and policymakers. Because AI models require large datasets to achieve many of their objectives, their widespread development is constrained by the willingness and ability of researchers to share data across institutions. This data-sharing, in turn, raises significant privacy risks. Yet many institutions do not have the necessary protections in place to guard against these risks.Footnote 122 Meanwhile, even when the data are shared, stored, and used properly, investigations have revealed that AI models often deliver inequitable results that favor certain subgroups of the population over others.Footnote 123
The future of AI in health care is a quintessential example of a health care evolution in need of guidance from federal policy. While Congress has yet to pass legislation to protect Americans from possible threats, the federal government has funneled billions of dollars into the AI industry through funding of research and development.Footnote 124 Further, through its role as one of the earliest and largest customers for AI products, the government is fueling the growth of the industry even further as it spreads into every aspect of health care.Footnote 125 Never let it be said that the private sector built our new AI-infused health care system alone. It is now, and will continue to be, a transformation that was built, as all health care transformations of the past seventy-five years have been, on the playing field the government built and continues to oversee.
Conclusion
All of the key developments in the evolution of health care, from health insurance to hospital growth to pharmaceuticals to AI, have seen the private sector use government infrastructure to achieve remarkable advances. At the same time, new variants of health care business have led to many of the same problems that have plagued the industry since its dawn. Fraud, abuse, profiteering, and inequitable access to diagnosis and treatment have reared their heads at every step. These threats to the health care system’s integrity are now joined by intrusions into patient privacy and unaccountable technologies, such as AI. Health lawyers have time and again stepped into the breach to help oversee and control these behaviors in a never-ending battle for safety, efficacy, fairness, justice, and the protection of patients’ rights. The profit motive does not care about such matters. It barrels forward toward whatever consumers — and government programs — will pay for, often indifferent to non-pecuniary consequences.Footnote 126 The government’s field of dreams created modern health care, but it has been the job of health lawyers to work to keep it level and to secure its benefits for everyone — a job that will become increasingly more essential and challenging as the game evolves.
