ACO = Arrogant Clinical or Aggressive Care Oligopoly?

In the 1970s, it was managed care organizations.  In the 1990s, it was vertically integrated health care systems.  In the 2010s, the fashionable concept for improving health care, apparently beloved by left-wing policy wonks and right-wing health care executives is the "accountable care organization." (ACO).  Development of the ACO is funded by the recently passed US health care reform legislation.  The official definition of ACO from the US Center for Medicare and Medicaid Services is: 

An Accountable Care Organization, also called an 'ACO' for short, is an organization of health care providers that agrees to be accountable for the quality, cost, and overall care of Medicare beneficiaries who are enrolled in the traditional fee-for-service program who are assigned to it.

Oddly enough, that seems like it could also describe a 1970s managed care organization, or a 1990s vertically integrated health care system. The only real difference is the idea that the ACO would be paid fees for service. All these similar concepts embody the notion that health care needs to be highly organized into big, bureaucratic organizations to improve quality and access while controlling costs.

Back in August, we warned:

There seems to be a strange and increasing alliance between politically- correct academic theorists and proponents of raw economic power. The theorists' notion of "accountable care organizations" seems to have become a great foil for would-be monopolists, yet the theorists have done nothing to show how their creation would really bring "power to the people." Meanwhile, maybe 'ACO' should stand for 'aggressive care oligopoly.' Meanwhile, be extremely skeptical of the latest health care fad, especially when it is supported both by academics and CEOs.

I am not sure you really heard it here first, but you did hear it here early. Now, three months later, our doubts have become main-stream.

Revisiting Sutter Health

n California, National Public Radio continued to document the increasing market dominance of the Sutter Health system (which we discussed in August here) as it marches toward becoming an ACO:

Through new construction and expanding its doctors' groups, Sutter Health is enhancing its position as one of the most dominant hospital systems in California. In addition, Sutter is further ahead of many competitors in fashioning itself into a so-called accountable care organization, responsible for coordinating care between hospitals, specialists and primary doctors.

A companion article gave examples of how this emerging ACO is becoming increasingly oligoplistic:

Hospital prices in the Sacramento region are among the highest in California, driven in large part by the negotiating clout of the hospital chain Sutter Health.

Over the last decade and a half, Sutter has gradually accumulated hospitals and amassed a roster of doctors who contract exclusively with the company. Sutter is now one of the largest hospital chains in California with 24 acute care hospitals.

'In this Roseville market, which is a big suburban area, the hospital is Sutter,' says John Murray, a veteran insurance broker. 'It's a lock right now. Because Sutter dominates the market, major insurance companies, like Blue Cross and Aetna, can't sell policies that exclude Sutter hospitals and doctors. That dependence means the hospital chain can dictate high prices.'

Concerns about Sutter's market dominance are also increasing:

'As Sutter gets bigger,' says Anthony Wright, executive director of Health Access California, a nonprofit advocacy group based in Sacramento, 'it can dictate higher prices and is less accountable for ensuring good quality because it has a lock on certain markets.'

Doubts in the New York Times

In the New York Times, Robert Pear reported:

When Congress passed the health care law, it envisioned doctors and hospitals joining forces, coordinating care and holding down costs, with the prospect of earning government bonuses for controlling costs.

Now, eight months into the new law there is a growing frenzy of mergers involving hospitals, clinics and doctor groups eager to share costs and savings, and cash in on the incentives. They, in turn, have deployed a small army of lawyers and lobbyists trying to persuade the Obama administration to relax or waive a body of older laws intended to thwart health care monopolies, and to protect against shoddy care and fraudulent billing of patients or Medicare.

Consumer advocates fear that the health care law could worsen some of the very problems it was meant to solve — by reducing competition, driving up costs and creating incentives for doctors and hospitals to stint on care, in order to retain their cost-saving bonuses.

'The new law is already encouraging a wave of mergers, joint ventures and alliances in the health care industry,' said Prof. Thomas L. Greaney, an expert on health and antitrust law at St. Louis University. 'The risk that dominant providers and dominant insurers may exercise their market power, individually or jointly, has never been greater.'

Skeptical Liberals and Libertarians
Amazingly, while ACOs seem to be supported by many left-wing policy wonks and right-wing health care executives, they have also rapidly engendered skepticism from both liberals on the left and libertarians on the right, and from within government and the private sector. For example, at the end of the NY Times article we find:

Dr. Donald M. Berwick, the administrator of the Centers for Medicare and Medicaid Services, hails the benefits of 'integrated care.' But, Dr. Berwick said, “we need to assure both patients and society at large that destructive, exploitative and costly forms of collusion and monopolistic behaviors do not emerge and thrive, disguised as cooperation.”

Dr Berwick is a well-known advocate of innovative approaches to improve the quality of care, but was tarred as a raving left-winger when he was nominated to his current position.

On the other hand, in the New York Post was an op-ed by Dr Scott Gottlieb:

I warned that the creation of 'accountable care organizations,' which put hospitals in control of all the doctors in their outlying areas, would lead to concentrated power over the provision of medical care -- turning physicians into salaried employees and reducing consumer choices.

Furthermore, he wrote:

Since the ACOs will have local monopolies, they'll also have little incentive to compete for more patients in an open marketplace. Yet this is the only incentive that would spur an ACO to truly innovate and improve its delivery of medical care and offer better services.

Private health plans vie to contract with the best doctors and hospitals, creating market prices for services and competition to improve outcomes. If the ACOs squeeze out this competition, the result will be a de facto 'single payer': Every market will be controlled by a single ACO,....

Dr Gottlieb writes frequently about health care and policy issues, and is a "resident fellow at the American Enterprise Institute."

Missing the Main Point: Doctors vs Business Executives as Leaders
At least it did not take long this time for the fundamental flaws in the latest fashionable health care reform effort to get attention. It is really striking that this time around, skepticism is coming from both liberals and libertarians.  Maybe we all have learned something from the failures of managed care and of vertically integrated hospital systems.

A Washington Post op-ed by Steven Pearlstein hinted at one fundamental problem with the ACO concept.

Most reformers believe ...that the best way to deliver affordable quality care is through organizations such as the Mayo Clinic, which coordinate physician and hospital services under one roof and are paid not on the basis of how many procedures they do but on the quality of the care they provide. These organizations tend to rely on salaried doctors, make extensive use of electronic medical records and evidence-based 'best practices,' and, in effect, take on much of the risk traditionally borne by insurers. Several provisions of the new health-care reform law encourage the formation of such 'accountable care organizations.'

Somehow, however, the supposed health care reformers seemed to have overlooked a crucial fact about the Mayo Clinic they are using as a model. The Mayo Clinic traditionally was basically a large physician group practice. It was run by physicians. Even now, the Mayo Clinic's CEO is a physician (Dr John H. Noseworthy) who had a substantial clinical and academic career. The CAO is a nurse, and the three top Vice Presidents are physicians.  I submit the fact that the organization was run by physicians, physicians who once swore to put their patients' clinical care ahead of all other considerations, was crucial to the Clinic's success in taking care of patients as well as maintaining its finances.

However, nearly all of the would-be ACOs we hear about now are centered on big hospital systems, run by business executives who have never taken care of patients, and never swore to put patient care ahead of anything. For example, the most advanced degree possessed by the CEO of Sutter Health is a Master's in Health Administration (see here). Sutter Health does not make biographical information about its top executives particularly easy to find, but according to the most recent (2008) 990 form posted on Guidestar, of its 19 top executives, only 2 had MD degrees. As we have seen time and again on Health Care Renewal, such executives have become extremely good at becoming rich in their jobs. (For example, according to the 2008 990 form, of those 19 executives, all had total compensation greater than $200,000, 16 had compensation greater than $500,000, and 9 had compensation greater than $1 million.) When things go wrong, these royally paid executives may take their golden parachutes and open the exit door, and jump on the slide.

The advent of ACOs reminds me of the advent of managed care. The original managed care organizations, exemplified by Kaiser - Permanante, were also not-for-profit large group practices run by physicians. However, the "managed care organizations" that evolved out of the 1970s law, favored by our glorious former President Nixon, were for-profit corporations run by business executives. Somehow, when legislators seek to promote better health care, the legislation they right often get the crucial details wrong.

The one good thing about ACOs seems to be that they have galvanized liberals and libertarians alike to worry about big, collective, bureaucratic health care organizations run by executives with no clear commitment to putting care of individual patients first.

More on Hospital Market Dominance, Enabled by Secret Pricing

This week two more articles appeared describing how large hospital systems use market dominance to charge more.  Naturally, both were in news publications, not scholarly health services research journals.

San Francisco

Kaiser Health News (via the Contra Costa [CA] Times) discussed hospital market dominance in the San Francisco area.  The article documented how particular systems can command higher prices. Consider the example of John Muir Health vs San Ramon Medical Center:

Often, a hospital's dominance in an area helps determine how much it can charge, experts say. Consider John Muir Health, a two-hospital nonprofit system in the East Bay. With campuses in Concord and Walnut Creek, John Muir has the biggest footprint in the local hospital market, accounting for 54 percent of all the acute care inpatient stays in 2009, more than any other hospital group, according to state data.

The hospital with the weakest market penetration is San Ramon Medical Center, a Tenet-owned, for-profit hospital, with 10 percent of the acute care inpatients.

The least the insurer Aetna paid John Muir for an outpatient colonoscopy was $3,185, according to Aetna's website, which tracks two years of payments. Aetna paid $1,483 to San Ramon Regional Medical Center for the same service. The least Aetna paid John Muir for an uncomplicated birth was $7,722, while its lowest price for a birth at San Ramon was $5,278.

Yet on broad quality measures, John Muir's hospitals generally score no better than San Ramon's, according to the California Hospitals and Reporting Taskforce, a nonprofit that produces hospital report cards published at Calhospitalcompare.org.

San Ramon ranks equal to John Muir's Walnut Creek campus in most major measures, including mortality rates in the intensive care units, overall patient satisfaction and maternity care. John Muir's Concord campus ranks below San Ramon on several measures, including mortality rate and patient experience, though John Muir was rated better in avoiding complications for patients on ventilators.

Then there is Sutter Health:

[Stanford University associate vice president for Benefits Les] Schlaegel says so many employees like to see doctors at the Palo Alto Medical Foundation, a doctors' organization affiliated with Sutter with a clinic near the Stanford campus, that the university feels obliged to keep offering insurance networks that include Sutter.

'Sutter basically has a stranglehold on Northern California,' says Schlaegel. 'They are strategically situated, both for hospitals and medical groups. They know purchasers need them. When you are strategically located, you can say 'this is our price and you can pay it.''

Secret Pricing
The ability of dominant hospitals to charge higher prices is facilitated by secrecy in which hospital pricing is cloaked

The hospitals haven't made it easy for consumers to comparison shop. State law requires hospitals to reveal their charges for specific services. But those charges don't reflect the lower negotiated rates insurers actually pay - rates hospitals usually insist be kept secret. The California Hospital Association has opposed legislation to ban such 'gag clauses'; the most recent of these bills died in the state Assembly in August.

Hospitals have also resisted a four-year campaign by the Pacific Business Group on Health, an employer coalition, and CalPERS to create a 'hospital value initiative' that would allow hospital comparison based on cost and quality of care.

Summary

In many cases, hospitals are able to keep raising prices beyond inflation because their sizes or reputations give them clout in negotiating rates with insurers, researchers say. Yet high prices don't always equate with superior care.

Quality measures for some of the Bay Area's most prestigious hospitals, including Stanford and John Muir, show that in some instances, less expensive competitors perform as well or better in their basic responsibilities, such as avoiding infections and high death rates for patients in intensive care.

'Some hospitals are able to charge higher prices than the market normally would bear, even without providing higher quality,' says Dr. R. Adams Dudley, a professor of medicine and health policy at the University of California, San Francisco. 'That means they're getting those higher prices without really offering more to patients or the rest of society.'

New York City


Meanwhile, a long feature story in New York magazine about the demise of St Vincent's hospital (see our post here) also discussed the market power of its competitors as one factor in its decline:

The city’s largest and most powerful hospitals, which are crucial to an insurer’s customers, exert their leverage to secure deals that are believed to pay well above the average margin; smaller hospitals, which are often located in low-income neighborhoods, have little choice but to accept the dismal rates dictated by insurers if they want to remain in the insurers’ plans. 'When the big players take their cut, there are only scraps left for everyone else,' says the CEO of an outer-borough hospital. “'United HealthCare couldn’t care less about having my hospital in their network. They tell me to take it or leave it.

Secret Prices

Like in California, market dominance is enabled by secret pricing:

the rates negotiated between hospitals and insurance providers are withheld from public scrutiny—even state health and insurance regulators are denied the information

Free Markets?

Secret prices determined by market power hardly sound like characteristics of a free market. Yet in New York, at least, they seem partially to be the result of the free market ideology of previous political leaders:

Then George Pataki took office in 1995, determined to allow hospitals to test their mettle in the free market by negotiating their own terms with insurers. It turned out to be an exercise in shock-therapy capitalism. Inexperienced at the bargaining table, hospitals engaged in intramural rivalry with each other, cutting unfavorable deals with insurers in order to hold on to patients in the short term. With their already thin margins pared down further by deregulation, many hospitals soon built up paralyzing debt loads. Even the largest and seemingly least vulnerable facilities decided that their best hope for survival was to get bigger. A flurry of mergers and buyouts ensued, and by the end of the nineties, the hospital system began to assume its current bewildering patchwork of partnerships and affiliations. Columbia Presbyterian and New York Hospital, both attached to elite medical schools, joined forces. NYU and Mount Sinai forged a deal (it later came undone). On the eastern edge of the city, North Shore hospitals merged with nearby Long Island Jewish, staking out an enormous swath of the hospital market on Long Island, Queens, and Staten Island. Beth Israel and St. Luke’s–Roosevelt, debt-ridden and left on the sidelines by the major academic hospitals, decided to try making a go of it together. It was unclear if bigger was actually better—for patients or the bottom line—but size seemed to offer hospitals a buffer against collapse.

By 2005, less than a decade into its dalliance with free enterprise, the city’s hospital system had taken on something of a post-Soviet tinge, with winners ruling the roost like oligarchs and losers reduced to a state of grim dependency. A pecking order emerged, with elite academic centers at the top, well-regarded independent hospitals like Lenox Hill in the middle, and community hospitals on the bottom.

Summary

We have previously written (for example, here and here) about how increasing market dominance by large, sometimes strategically located, and sometimes politically well-connected (e.g., see here) hospital systems run by conflicted leaders. This seems like another unintended consequence of the "free markets solve all problems" ideology, possibly fueled by conflicts of interest that has done so badly in our financial arena (see here). What some of these free market enthusiasts seem to forget, their forgetfulness perhaps fueled by payments received from the large corporations that have profited from this movement, are that true free markets are hard to maintain. This is particularly so in health care, in which knowledge is asymetric, outcomes are uncertain, and sick and anxious patients have trouble making cool, rational choices (as per Arrow, see this post.)

But if the free market enthusiasts really believe in free markets, why have they not been out campaigning to prevent the "unfree" characteristics, like secret pricing, of current health care markets?  Of course, ending secret pricing might compromise the ability of their financial sponsors to keep earning their millions

How Oligopolists Rationalize Their Market Domination: the Examples of Sutter Health and the Carilion Clinic

Advocates of laissez faire commercialized health care often trumpet the advantages of competitive markets as a rationale for deregulation.  While there are theoretic, and possibly empiric reasons to think that competitive markets are the optimal way to distribute goods and services, we recently discussed aspects of health care that make it extremely hard for health care markets to be ideally competitive. 

Meanwhile, two news articles gave some case-based evidence about how current health care markets are hardly competitive.  

Sutter Health

A Bloomberg article focused on Sutter Health in northern and central California. Sutter Health commands a substantial part of a very large market:

Sutter Health Co., the nonprofit that owns Sutter Davis, has market power that commands prices 40 to 70 percent higher than its rivals per typical procedure -- and pacts with insurers that keep those prices secret.

Sutter can charge these prices because it has acquired more than a third of the market in the San Francisco-to-Sacramento region through more than 20 hospital takeovers in the last 30 years, according to executives of Aetna Inc., Health Net Inc. and Blue Shield of California, who asked not to be named because their agreements with Sutter ban disclosure of prices.

Also,

Operating as a nonprofit, it has $8.8 billion in revenues, 24 hospitals, 17 outpatient surgery clinics and a 3,500-doctor network, making it the largest health-care provider in an 11- county region -- from San Francisco Bay to the Sierra Nevada mountains -- where 10 million people live.

Sutter has 35 percent of the revenue and 36 percent of beds that compete for patients in the region, according to a state hospital database, including 100 percent of beds the state tracks in Placer and Amador counties east of Sacramento.

Sutter care seems to cost a lot more than care from other doctors and hospitals:

After Mark Logsdon tore a ligament in his knee skiing at Lake Tahoe in March, he returned home to suburban Sacramento and had an MRI scan at Sutter Davis Hospital.

Sutter’s price for the knee scan was $1,271, payable by Logsdon and his insurer. Exactly the same MRI at one of the local imaging centers owned by Radiological Associates of Sacramento would have cost $696 -- 45 percent less.

A few other examples of Sutter's prices compared to others;

'Instead of leveraging its system to be more cost- effective, we’ve seen Sutter leveraging its system for monopoly pricing,' said Peter V. Lee, who in June became director of health-care delivery system reform for the U.S. Department of Health and Human Services. Lee was interviewed while he worked at the Pacific Business Group on Health, a coalition that includes Chevron Corp., Walt Disney Co., General Electric Co., and Wells Fargo & Co.

In San Francisco, Aetna pays Sutter’s California Pacific Medical Center in a range with a midpoint of $4,700 for an abdominal CT scan, compared to $3,200 at St. Francis Memorial Hospital, owned by Catholic Health Care West. For colonoscopies, Aetna’s midpoint price is $3,200 at Sutter’s flagship CPMC and $2,800 at St. Francis Memorial.

In Palo Alto, Aetna pays Sutter $349 per visit for new patients to see Manju Deshpande, a family doctor in Sutter’s Palo Alto Medical Foundation clinic. Three miles away, Paul Ford’s Stanford Medical Group receives $222. If the patient needs an immunization, Aetna pays Palo Alto Medical $85, and Stanford Medical, $16. Deshpande removes wax from the ear for $175. Ford scoops it out for $104.

Down the road in Silicon Valley, when obstetrician Sarah Azad, a solo practitioner, delivers a baby for a patient covered by Aetna, the insurer pays her $2,052. When Nicole Wilcox of Sutter’s Palo Alto Medical Foundation does the same job, Aetna pays Sutter $5,890.

The doctors practice blocks apart in Mountain View, California. Performance isn’t an issue -- Azad has Aetna’s top rating for quality of care and trained Wilcox during residency.

The Sutter CEO, of course, denies there is a problem:

Sutter operates in a competitive market, Chief Executive Officer Patrick Fry, 53, said in an interview. 'I don’t see Sutter Health as having market power, given the choices that employers can make,' Fry said. 'The market has a lot of room to make a lot of decisions.'

The people who most praise competitive markets often seem to be those who have done the most to reduce the competitiveness of these markets.  The CEO also trotted out another old saw, that his organization has grown not to charge more, but to be more efficient.

While Sutter may have higher 'unit' prices than its competitors, Fry said, it is not the most costly for patients over the long run because its integration of hospitals and doctor groups allows it to provide more efficient care, cutting down on the number of procedures.

'Our mission isn’t to maximize profits,' Fry added. 'Our mission, to the extent we can, is to optimize services.' Insurers and patients have many alternatives to Sutter, according to Fry.

That is a tune would-be monopolists have been singing at least since the days of the "robber barons" and their monopolies such as Standard Oil.

Of course, he is likely to defend a system that makes so much money and pays him and his buddies in top management so much, (and, contrary to his statement above, seems to have maximized profits):

Sutter, with 48,000 employees, was among the most profitable hospital groups in the U.S. in 2009, with income of $697 million, up more than three-fold from 2008 due to large investment gains, on revenue that grew 6 percent to $8.8 billion.

Its 5.2 percent operating margin -- or operating income as a percentage of revenue -- was 73 percent higher than the median for all nonprofit hospital systems in 2009, according to Standard & Poor’s.

As of Dec. 31, Sutter had a $2.63 billion investment portfolio. Sutter paid Fry $2.8 million in 2008, according to its latest Internal Revenue Service filing. His top 14 lieutenants made between $830,000 and $1.8 million each.

The article on Sutter emphasized how the strategic use of secrecy has helped Sutter maintain its remunerative ways:

Sutter doesn’t allow its prices to be disclosed on insurers’ websites because it believes the information is often misleading and doesn’t reflect the variables of each patient’s case, [Sutter spokesman William] Gleeson said.

Of course, keeping prices secret just makes the market even less like an ideally competitive one:

As Sutter’s confidentiality terms show, the actual prices that hospitals receive are often kept secret by insurers. Patients in need of hospital care, especially in emergencies, often can’t travel very far, restricting competition. And if they have health insurance, they have little incentive to price shop.

Finally, the article reminds us that the latest fad from health policy and health management circles (which seem increasingly to overlap), "accountable care organizations," may just be a pretext for even more market consolidation:

The federal Patient Protection and Affordable Care Act is looking for $500 billion in savings over the next decade to help pay for extending coverage to 32 million uninsured Americans. Yet it doesn’t address the problem of market concentration -- and may make it worse, said Robert Berenson, a physician and policy analyst at the Urban Institute in Washington D.C.

The 'unchecked' clout of hospital and physician groups in California is a 'cautionary tale for national health reform,' Berenson said in a February article in the journal Health Affairs. He warned that incentives in the new legislation to improve treatment by promoting doctor-hospital alliances -- called 'accountable care organizations' -- could backfire by strengthening providers’ bargaining leverage.

Carilion Clinic
A Washington Post article discussed the example of Carilion Clinic in Virginia, whose increasing market power we had blogged about in 2008:

Railroads put this city on the map, but the king of the domain is now health care -- or rather, the Carilion Clinic.

Carilion owns the two hospitals in town and six others in the region, employs 550 doctors and has set off a bitter local debate: Is its dominance a new model for health care or a blatant attempt to corner the market?

The Carilion story emphasized again how the "accountable care organization" meme is being used to justify market consolidation, allowing health care oligopolies to appear politically correct:

Carilion says it represents an ideal envisioned by the nation's new health-care law: a network that increases efficiency by bringing more doctors and hospitals onto one team, integrating care from the doctor's office to the operating room. The name for such networks, which the new law strongly promotes with pilot programs, is accountable care organizations, or ACOs -- providers joining together to be 'accountable' for the total care of patients, with incentives from insurers to keep people healthy and costs down.

Note that this political correctness is also used to justify further consolidation of power by limiting outside referrals:

Independent doctors say Carilion is urging its employees to refer patients only to providers within the Carilion network, cloaking its expansion in the lingo of health-care reform.

Of course, the Carilion CEO also denies anything but the most altruistic intent, but he too is making a lot of money from the current system:

[Edward] Murphy, Carilion's chief executive who earned $2.3 million in 2008, acknowledges that providers holding excessive leverage over insurers is cause for concern but argues that ACOs can be a corrective.

Summary

We noted earlier this week that multiple kinds of uncertainty (e.g., about diagnosis, prognosis, and the effects of treatment), and information asymmetry make it theoretically difficult for the health care market to be truly competitive. Meanwhile, there is increasing evidence that the market is actually uncompetitive. Although there are many hospitals and health insurers across the US, in many areas there are very few insurers and very few hospitals or hospital systems from which to choose. We have previously blogged about how market dominant hospital systems seem to be able to charge more than any others.

In the 1960s, it became recognized that physicians' professionalism, hospitals' devotion to their missions, and sometimes even (gasp) government regulation might partially compensate for distortions in the health care market. However, as supposed free market advocates became more powerful, they pushed for the commercialization of medicine and hospitals, reducing professionalism and mission support, and the hollowing out government regulation. (However, why did the people who attacked medical societies' codes of ethics as monopolistic have no interest in attacking market domination by insurers or hospital systems?  Inquiring minds want to know.)

As we said last time, true health care reform would help physicians and other health care professionals uphold their traditional values, including, as the AMA once stated, "the practice of medicine should not be commercialized, nor treated as a commodity in trade." True health care reform would put health care "delivery" back in the hands of mission-focused, not-for-profit organizations, which put patients' health, safety and welfare first.

Meanwhile, these latest stories about market dominating hospital systems suggest some additional lessons.

Secrecy is the would-be monopolist's best friend. However, it is hard to think of very many kinds of information that hospitals really ought to be able to keep as proprietary secrets. As usual, sunshine is the best disinfectant.

There seems to be a strange and increasing alliance between politically- correct academic theorists and proponents of raw economic power. The theorists' notion of "accountable care organizations" seems to have become a great foil for would-be monopolists, yet the theorists have done nothing to show how their creation would really bring "power to the people." Meanwhile, maybe "ACO" should stand for "aggressive care oligopoly." Meanwhile, be extremely skeptical of the latest health care fad, especially when it is supported both by academics and CEOs.
