CHAPTER 10
THE STICKS
Let Information Flow

Standing in the brightly lit supermarket aisle, I examined the box of raisin bran cereal I was thinking of buying. In an instant, I knew its price, nutritional qualities, calories, and expiration date. All this information was printed right on the package. The information is there because the government requires its publication. Yet if I needed a mastectomy for breast cancer, I would know nothing about the results achieved by a surgeon when he or she operates on people like me for this disease or by the hospitals in which he or she performs the surgery. I would not even know their prices.

What does not get measured does not get managed.

Because we do not measure the quality and prices of our health care providers, Jack Morgan died: it is highly unlikely that he would have chosen the HMO had he known the outcomes of its treatment of kidney transplant patients. One little statistic can make the difference between life and death: how long the HMO's patients—those who are as sick as Jack was—wait for their kidney transplants.

Sunshine is the best disinfectant.

In this chapter I discuss how to let the sun shine in on our health care system through the creation of a new government agency that forces transparency.

The Impact of Information on Markets

Information makes ignorant people smart.

I confess: I have only the dimmest notion of how a car functions.

After all, a car is a high-tech device, studded with microchips. My notions of the mechanical compression and ignition of gasoline that lead to an explosion whose energy ultimately rotates the wheels of a car are as dated as my first car, the 1957 Dodge that I purchased in 1966. It got seven miles to the gallon, rivaled a stretch limo in length, and belched pollutants.

I do not think that I am alone in my ignorance. When I see someone in an automobile showroom peering under the hood of a car, I think to myself, "What the heck are you looking at?" Nevertheless, I can readily find the kind of car I want at a price I am willing to pay. My quality choices have increased substantially since 1966, while the cost of a car has decreased as a proportion of income:1 as a result, 48 percent of the poor own cars, and 14 percent own more than one.2

How is it that an ignoramus like me can easily find cars that are better and cheaper?

And, as only one person in a vast sea, why am I not pillaged in the automobile market?

The answers to these questions rest on an understanding of how markets work—how weak, solo participants, like me, are offered better and cheaper products. Two ingredients are crucial.

One is information. It enables me to be an intelligent car shopper, despite my ignorance.

I peruse the rating literature for a car that embodies the attributes I value: safety, reliability, environmental friendliness, and price. Objective, trustworthy information about these attributes is easily available to me. When I studied Consumer Reports for cars with these attributes, two brands satisfied my requirements: Volvo and Buick. I skipped the earnest reviews of how the engines work, fuel efficiency, comfort, handling, styling, and so on. Safety, environmental quality, reliability, and price—these are what interest me.

I opted for the Buick. Although it was not quite as reliable as the Volvo, it was cheaper.

But many who shared my views of the qualities desired in a car opted for the Volvo. It grew from an obscure Swedish brand to sales of 456, 000 cars in 2004.3 When Volvo's rivals saw that a meaningful number of customers were interested in safety and reliability, they introduced these qualities into their cars. In the quest for safety, Ford, for example, acquired Volvo, and other automobile manufacturers improved their reliability.4 By 2005, U.S. cars exceeded European ones in reliability, and the Japanese cars had only a small edge.5 Quite a change from 1980, when U.S. cars were three times as unreliable as Japanese ones and twice as unreliable as European vehicles.6

So information made me smart and caused car manufacturers to respond with the qualities that I wanted; but what stops the car manufacturers from refusing to cut their prices? After all, I am only one person.

The critical second ingredient for an effective market is a small group of marginal, tough-minded buyers. At a high price, there are only a few buyers who are more or less price insensitive. The good news for businesses is that these customers are willing to pay a very high price. The bad news is that there are only a few of them. To attract more customers, suppliers reduce their prices. The increased volume of customers more than compensates for the reduction in price. Suppliers continue to cut prices until they hit a brick wall: the last picky, tough-minded customers who clear the market. The price these tough-nosed buyers are willing to pay is roughly equal to the marginal cost of making the product. The rest of us benefit from the assertiveness of the last-to-buy crowd. And it is a relatively small group. A McKinsey study showed, for example, that only 100 investors "significantly affect the share prices of most large companies."7

These hard-nosed buyers are highly adept in finding, interpreting, and using information. They are the show-me crowd, the marginal consumers bloodlessly depicted on the bottom of the Economics 101 downward-sloping demand curve. This relatively small group of demanding consumers rewards suppliers who reduce price and improve quality.

The car market illustrates their impact. Currently, automobile prices are the lowest in two decades. In 1991, for example, the average family required 30 weeks of income for the purchase of a new vehicle; but by 2005, a new vehicle required only 26.2 weeks of their income—a 14 percent decline.8 Simultaneously, automobile quality is at an all-time high.9 The range of choices is better too, as the quality differences between the best and worst manufacturers have declined.10

Health Care Consumers of Information

As in the automobile market, smart, informed consumers—consumers who have access to good information and the freedom to choose health care plans and providers, optimized in classic Economics 101 fashion will make our health care system better and cheaper—For example, the satisfaction and cost data collected by the Buyers Health Care Action Group (BHCAG), the Twin Cities' employer coalition described in Chapter 7, encouraged patients to leave high-cost/low-satisfaction plans for lower-priced/higher-satisfaction plans, thereby prompting physicians to offer more bang for the buck. The program led to a nearly 20 percent drop in high-cost/low-satisfaction plans and a 50 percent increase in lowcost/high-satisfaction plans.11

Even in the absence of consumer control, the gathering and dissemination of information exerts powerful effects on suppliers.12 In accounting, this phenomenon is known as the audit effect: 13 firms improve their management in anticipation of an accounting audit. In health care, many of the reviews of the impact of published performance data on physicians, hospitals, and insurers have concluded that they resulted in improved outcomes and/or processes.14 One study of obstetrics performance found that hospitals whose results were disclosed publicly had significantly greater improvement than those with private reports.15

Yet health care policy analysts argue that a consumer-driven health care system cannot work because average consumers will be stymied by the process of selecting among differentiated health insurance products.16 These analysts may fail to appreciate the impact of those tough-minded buyers on a market. Nevertheless, their argument does raise a question: does a marginal group of tough-nosed, market-clearing consumers exist in health care?

To explore this, let's take a minute to focus on characteristics of American consumers. Current generations are much better educated: In 2004, 27.7 percent of the population had attained a college education or more, and 85.2 percent were high school graduates.17 In 1960, in contrast, fewer than half the people were high school graduates, and only 7 percent had a college education.18

Higher levels of educational attainment increase not only income and ability but also self-confidence (referred to as "self-efficacy" in the health policy literature19 ). For example, churchgoers increasingly stand rather than kneel, likely expressing their notion that a service provides an opportunity for a personal encounter with God rather than for reverential worship. About 80 percent of the pews ordered from the country's largest manufacturer now come without kneelers.20

Affluent Web surfers embody this self-efficacy—they spend more time than others searching for information on the Net before making a purchase and are much more likely to buy, once they have found a good value for the money.21 Those who focus only on their affluence miss the point: affluent or not, they eat the same bread, buy the same appliances, and wear the same jeans. The same Toyota is sold in poor inner-city areas and affluent suburbs. The activism of the affluent Web surfers improves these products for everybody.

Consumers surf the Web for health care information. A 2005 report found that 95 million people used the Internet for health information,22 6 million of them daily.23 Some even study medical information, such as the millions of people who spent an average of 20 minutes at the government's National Institutes of Health Web site, studded with arcane medical journal articles.24 few even express their activism directly by mastering medical skills, such as CPR and the use of external defibrillators.25

The assertiveness and self-confidence that typify marginal consumers are evident in these health care Internet users. They agree more than average U.S. adults with the following statements: "I like to investigate all options, rather than just ask for a doctor's advice" and "People should take primary responsibility and not rely so much on doctors."26 Their pragmatism is apparent too. They do not search idly. More than 70 percent want online evaluations of physicians,27 and when they obtain the information, they use it.28 Consumers are willing to change hospitals in response to information about their quality.29 Nor is consumer assertiveness limited to the United States. For example, 70 percent of Canadian doctors note that their patients are briefed by Internet information.30

Thus, although average buyers of health care are not experts, individual consumers can reshape the health care system. As with the automobile markets, the markets that make up the health care system will be guided not by average consumers, but by the marginal customers who drive the toughest bargain. What they need is information.

The Role of Government in Creating Transparency

The role of government in providing transparency is surprisingly controversial. In the view of Nobel economics laureate George Stigler, the truth will out in markets as competitors expose each others' weaknesses or market analysts unearth it.31 Stigler's analyses have asserted that government regulation of information disclosure is not essential to the efficiency of markets.32 Although his claims and similar research have been widely tested,33 the empirical research examining the necessity of government action to ensure an efficient market has not yet settled the question.

Rather, the debate must fundamentally be resolved on a theoretical basis: information disclosure is a public good—that is, one in which the government must be involved—in the sense that it enables free riders—those who do not pay for the benefits they receive. Because disclosers cannot charge all users of the information for the benefits they derive, they lack incentives for full disclosure.,34 As a result, the quantity of publicly available information may be under-supplied or issued selectively, favoring some recipients and excluding others.35 For this reason, the quantity and quality of the information currently available in health care through voluntary measures is deficient.

The Failure of Voluntary Transparency

Voluntary transparency does not work. Consider the case of the voluntary Greater Cleveland Health Quality Choice Coalition, a group of local area businesses who joined forces to collect hospital performance data. The effort was widely lauded. Forexample, one hospital claimed that the significant decrease in its rate of caesarean sections was "purely driven by the Cleveland Coalition."36 An evaluation concluded that reductions in risk-adjusted mortality rates and lengths of stay were linked to the performance reports.37

Nevertheless, the effort collapsed when the famous Cleveland Clinic left the group, allegedly because it did not like the performance ratings process. Notes a local doctor, "What the Clinic really didn't like is that they weren't shown to be the best at everything."38 And the employer group that sponsored the effort did not actively use its results. The only hospital to achieve great results expected that the data would yield many new patients as employers referred their enrollees there, but the predicted surge never materialized. Noted one employer, lamely, "We weren't that aggressive."39 As we saw earlier in this book, the bureaucratic and paternalistic human resources staff relies on limited choice and managed care as agents of change. They donot believe in the power of information to transform health care.

Voluntary, hospital-and insurance-led mechanisms don't work well either. A Modern Healthcare editorial about the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), the national hospital-accreditation group, whose governance the providers dominate, noted: "JCAHO [has] … repeatedly failed at initiatives designed to judge hospitals and other healthcare providers based on their performance—how well they take care of sick people. The projects always are announced withmuch fanfare and heady names such as 'Agenda for Change.' And they're invariably scrapped, watered down or delayed."40 An academic evaluation found no correlation between JCAHO scores and outcome measures, such as mortality and complications, for the hospitals it studied.41 Similarly, health insurance buyers may question the value of the health insurance industry–led accreditations because virtually everyhealth plan has it.42 Doctors also opt out of voluntary reporting efforts. A study of a voluntary error reporting system found that only 2 percent of the nearly 100,000 responses were filed by physicians.43

The Impact of the U.S. Securities and Exchange Commission (SEC) onFinancial Transparency

But when the federal government required disclosure, we got it! The story of how the U.S. SEC's requirement for transparency transformed the money markets is told below.

Virtually every interest group that has been required to measure its outcomes claims its work is so diffuse that its impact cannot be measured. Such claims delayed the measurement of the performance of businesses until the mid-1930s. The stunning absence of information at that time is analogous to the situation in today's health care system: in 1923, only 25 percent of the firms traded on the New York Stock Exchange provided shareholder reports.44 Investors were flying blind then, just like today's health care consumers.

The absence was all the more surprising because accounting, the measurement tool for business performance, has existed since the middle of the fifteenth century, when double-entry bookkeeping was first codified.45 But business executives' claims that accounting could not accurately measure company performance and that the cost of measurement exceeded its benefits prevented widespread disclosure of information about the economic performance of the firms they led.46

In the 1930s, U.S. President Franklin Delano Roosevelt (FDR) promulgated the laws that created the SEC. Bucking powerful business opposition, state government involvement, and his own advisors' counsel that he promote laws to grade the firms in the security markets, FDR instead created the SEC to compel audited disclosure of the performance of publicly traded firms, using generally accepted accounting principles (GAAP).47

The SEC is a genuine private-public partnership. The governmental SEC requires disclosure, but the auditors and the organizations chargedwith creating and implementing the audit rules (including the promulgators of GAAP) are housed in private organizations such as the Financial Accounting Standards Board (FASB).

Governmental regulation of securities is nothing new. As early as 1285, King Edward I required licensing of London brokers.48 But FDR's SEC differed from traditional regulation that relied on authorities to evaluate the worthiness of a security. He opted for sunlight. As he noted: "The Federal Government cannot and should not take any action that might be construed as approving or guaranteeing that…securities are sound.… " Rather, his SEC was a "truth"agency, established to ensure full disclosure of all material facts. In Roosevelt's words, "It puts the burden of telling the truth on the seller."49 To put teeth in its mission, the SEC was given the power to enforce "truth in securities" and to regulate the trading of securities in markets through brokers and exchanges.

Like all human endeavors, the SEC is not without faults. The corporate accounting and governance problems of public U.S. businesses in the 1990s were exacerbated by lax SEC enforcement.50. Nevertheless, the transparency created by the SEC enabled the broad participation of average Americans in the securities markets and the markets' efficiency.51 (Efficiency in this context is the degree to which information is so broadly disseminated throughout a market that no participants can benefit from having access to special information available only to them.) Financial reporting reduces the investor's risk, narrows the differences between sophisticated and less sophisticated investors, and reduces the firm's cost of capital. Currently, the U.S. SEC serves as a worldwide model: for example, foreign firms that switch to U.S. transparency practices and standards benefit financially.52 For this reason, Japan isconsidering adoption of the SEC model to curb the substantial transparency failures of its capital markets.53

All measuring tools improve with use. Accounting was not nearly as accurate a measure of economic performance in 1934 as it is today. No doubt, accounting will improve in the future. In 1687, Newton first measured gravity. By 2000, physicists could measure the minute energy of a tau neutrino buried deep within an atom.54 In 1953, Crick and Watson first measured the structure of DNA. By 2007, biologists could manipulate the structure of individual genes.55 Today's health information measures will also be refined with practice and time.

Private-Sector Sources of Financial Information

Much of the information that lies at the heart of the efficiency of the financial markets comes not from the SEC but from three private-sector groups: the businesses themselves, the FASB, and the accounting profession. The interaction among these groups promotes fuller consideration of diverse points of view. Unlike a government agency, these organizations do not sing out of one hymnal. And their private sector nature requires the political and financial backing of their supporters for continued existence, unlike government organizations, which can continue to exist with little regard for theirimpact on their constituency. Indeed, the predecessors to the FASB collapsed when their GAAP pronouncements could not find broad-based support.

To be "certified, " the independent accountants who audit the financial statements must pass examinations and fulfill stringent educational and practice requirements. Many work in one of the four large U.S. accounting firms that audit the companies that account for nearly 99 percent of our stock market's capitalization.56 Accounting firms may be held legally liable for negligence, fraud, and breach of contract. One firm, for example, paid the SEC $50 million in penalties to compensate investors in the Adelphia scandal.57 Arthur Andersen, once among the largest public accounting firms, collapsed in the wake of the Enron debacle.58 Accountants have even been found criminally liable.59 In 2005, for example, the former chief financial officers and controllers of the large public firms WorldCom, Enron, Adelphia, and HealthSouth were serving prison terms for fraud.60

In abdicating much of its authority to set accounting standards to the private sector, the SEC recognized the following advantages: (1) Practicing accountants were closer to the firms and thus could more accurately identify emerging issues; (2) private-sector involvement encouraged greater compliance than government mandates; and (3) the SEC could more readily audit the work of the private-sector information disclosers than its own, thus resolving a conflict of interest.61

But the accounting abuses that emerged in the early twenty-first century caused a shift in this stance. Many blamed the structure of the accounting firms for these debacles, citing the conflict of interest created by their simultaneously offering lucrative consulting and low-profit auditing services to clients. Past SEC attempts to bar accountants from offering consulting contracts had been stymied by the Congress.62 This time around, the SEC relied on its internal rule-making authority to reclaim some of its powers. It introduced rules to prompt faster, more complete disclosure and to create a new entity to oversee the accounting professionals.63 Similarly, the rule-making Financial Accounting Standards Board has been chastened by the loopholes that its complex rules enabled and has promised to simplify and streamline them in the future.64

A Health Care SEC

U.S. securities markets feature the characteristics that health care consumers want: (1) prices are fair in the sense that they reflect all publicly available information, and (2) buyers use this information to reward effective organizations andpenalize ineffective ones. Thus, in the financial markets, positive disclosure of resultslowers the firms' cost of capital.65

If these characteristics were present in health care, they would divertresources from health providers that offer a bad value for the money to those that offer a good one. Poor-value-for-the-money providers would shrink or improve. Good-value-for-the-money providers would flourish.

Current health care consumers have little information about the qualityof their providers. Indeed, they have better information on raisin bran cereals—they need only read the label—than they have on the surgeon who will operate on their breast or prostate cancer tumors. Publication and widespread dissemination of data about the quality of individual providers, as measured by generally accepted health care outcome principles and audited by certified, independent appraisers of suchinformation, will help ameliorate this problem. Eventually, independent analysts will usethis information to compile readily accessible ratings of providers, similar to Morn-ingstar's excellent system for classifying and rating mutual funds.

The key to achieving these desirable characteristics in health care is legislation for a health care SEC that replicates these essential elements of the SEC model:

1. Private-sector analysis The evaluation process is primarily conducted by private-sector analysts, who disseminate their frequently divergent ratings. To encourage similar private-sector health care analysts, the new agency should require public dissemination of all outcomes for providers, including clinical measures of quality, and related transaction costs.

2. Focus on outcomes, not processes The SEC and FASB focus on measuring the financial performance of organizations. FDR firmly rejecteddictating business processes or rating businesses as appropriate roles for the SEC.

3. An independent agency with a singular focus The SEC is an independent agency charged solely with overseeing the integrity of securities and the exchanges on which they are traded. Because of these clear goals and organizational characteristics, the SEC's mission is not muddied, and it can be held clearly accountable for its performance.

4. Penalties The SEC requires firms that tradetheir securities in interstate markets and all such market makers to register with the agency. A corresponding health care agency would oversee the integrity and require public disclosure of information for entities that provide health insurance and services. Like the SEC, it would be armed with powerful penalties for undercapitalized and unethical market participants, including imprisonment, civil money penalties, and the disgorgement of illegal profits.66

5. Private-sector disclosure and auditing The SEC relies heavily on private-sector organizations that contain no governmental representation. The new health care agency should similarly delegate the power to derive the principles used to measure health care performance to an independent, private, nonprofit organization that, like the FASB, represents a broad nongovernmental constituency. The agency would require auditing of the information by independent professionals, who would render an opinion on the information and bear legal liability for failure to disclose fairly andfully.

The SEC is essentially a profit center, generating a substantial surplus from its filing and penalty fees that offsets its billion-dollar budget.67 A health care version of the SEC could be similarly self-financed, offsetting its expenses with filing fees and fines collected from its constituency.

How Not to Make Health Care Transparency Happen

Unfortunately, many well-intended proposals undermine one or more ofthese essential SEC characteristics.

Private-Sector Analysis

All too often, these proposals require that the health care regulators evaluate and micromanage health insurers and the markets in which they operate.68 But these suggestions place inappropriate responsibilityon the regulator. One organization should not simultaneously assure the release of accurate data and analyze the data. After a while, the organization might be sorely tempted to skew the data so that the analysis is proven correct. As an example of the kind of pressure that a government agency can exert on analysis, 15 percent of the Federal Drug Administration's scientists have said they were inappropriately asked to exclude or alter information in their conclusions.69

In the financial markets, neither the SEC nor the FASB assesses the quality of the output produced by corporations. Instead, they ensure the provision of reliable, useful information. Private-sector intermediaries, including firms such as Morningstar, Merrill Lynch, and Standard & Poor's, can then analyze the information and present it to consumers.

Other proposals include the government as a participant in private, nonprofit FASB-like entities such as the National Quality Forum.70 This kind of organizational structure places government on both sides of the table, allowing it to act as both regulator and standard setter. It thus compromises the checks and balances that exist between the private-sector FASB and the governmental SEC.

Measuring Outcomes, Not Process

The SEC focuses on measures of financial outcomes —suchas profitability, liquidity, and solvency. It does not dictate process —how businesses should achieve these results.

The pay-for-performance (P4P) movement is a worrisome example of the confusion between the two kinds of measures.71 A focuson measuring process may deter innovative improvements in quality. For example, one expert concluded that "in diabetes the emphasis on measuring preventative processes of care, rather than assessing outcome measures such as blood pressure and the markers of sugar in the blood of diabetics, may have the unintended consequence of diverting resources and attention from [the] clinically more productive tasks."72

An Independent Agency with Singular Focus

Some proposals would compromise the focus and independence that characterize the SEC's organizational structure. They recommend, for example, that an SEC-like agency be housed under the Department of Health and Human Services (HHS),73 which oversees the government payments for Medicare and Medicaid, among other activities. This organizational setting could compromise the mission. Because HHS accounts for a large fraction of U.S. health care payments, a health care SEC housed under its wings could be focused on serving the interests of payers, rather than consumers.

Further, the clear accountability of a free-standing agency would be lost in this setting. President George W. Bush's first SEC commissioner was forced tostep down because of the SEC's failures in ensuring transparency in the financial markets. Because the SEC was a separate agency, he was clearly responsible for its failing; but who in HHS was held responsible for similar failings with implementation of its drug plan?74 Although 5 percent of all Medicare recipients who called its drug plan help line were disconnected and nearly a third found the advice difficult to use, inappropriate, or erroneous, no one was held responsible for these failings.75

Opposition to Transparency about Health Care Prices and Quality

We live in an information age, surrounded by ubiquitous newspapers, televisions, telephones, computers, radios, magazines, and books, available worldwide, round-the-clock. They address three of our senses—sound, vision, and, for the vision-and hearing-impaired, touch. In 2004, the 8 million people who said they had created a blog were visited by 14 million viewers.76 The ubiquity of information responds to people's desires: when there is no demand, there is nosupply.

The best sources combine information and accessibility: Morn-ingstar's and Zagat 's restaurant guides' pithy reviews, J.D. Power's powerful brand name, and Consumer Reports ' accurate, comprehensive ratings typify these qualities. But those who do not like these sources can find many others: If investors judge Morningstar excessively terse, the SEC's EDGAR system contains much more information about publicly traded corporations.77 If they prefer professional restaurant reviewers to Zagat 's amateurs, they can turn to the Boston Globe 's "Food"section or its equivalent in their own hometown paper. If they question J.D. Power's objectivity or feel that Consumer Reports is biased against American cars, they can turn to the federal government's data about cars and airlines, such as those provided by the National Highway Traffic Safety Administration and the Federal Aviation Administration,78 or Car and Driver magazin and Consumers Digest. The point is that there is a wealth of information available, and interested consumers can drill down into it as little or as much as they need.

The providers of information help themselves too. In 2006, Google's founders became billionaires because they helped people achieve greater productivity by answering their questions easily and efficiently. Michael Bloomberg also gained billionaire status because he provided information that helped people to invest in financial instruments with confidence.79

Many complain about the absence of similar consumer-driven health care quality information.80 The wired generation is especially demanding—80 percent of respondents have noted that the absence of quality information was the most negative aspect of e-health plans.81 When information is available, health care consumers have stated that they would use it.82 Prescient entrepreneurs and wannabe billionaires are already providing them with some of the information they want. The market value of the WebMD consumer health care portal, for example, doubled in four months after itsSeptember 2005 IPO.83

But many powerful opponents, including the academics and providers discussed above, constrain its development.

Health Care Providers' Opposition to Information

Providers who like the theory of consumer-based choice and information may dislike the reality—the requirement that they be accountable for their performance. More than two-thirds of surveyed physicians have said that the general public should not have access "to information on clinical outcomes."84

To urge their cause, some may claim that performance is intrinsically unmeasurable. But if the performance of medicine cannot be measured, there is no basis forteaching, research, or clinical practice in the field. Others may claim that only they can correctly interpret the data. In this claim, they misunderstand the role of marginal consumers in making markets work.

Yet other providers note the cost and difficulty of obtaining reliable data about the performance of providers who see few patients with a particular medical condition. For example, one Journal of the American Medical Association article explained that the cost of collecting the data no doubt exceeds its benefits.85 The cost? As much as $0.59 to $2.17 per member per month. And thebenefits? The article does not address the question, perhaps because the benefits easily exceed the data collection costs. For example, if quality data improve the costs of treating a diabetic by as little as 1 percent, the data collection costs will be repaid fiftyfold in less than one year.86

The same report also notes that many data cannot be reliably measured for most doctors because they treat so few of the sick. For example, "a physician would need to have more than 100 patients with diabetes…for a profile to have a reliability of 0.8 or better, while more than 90 percent of all primary care physicians at theHMO [he studied] had fewer than 60 patients with diabetes."87 A hospital-based study similarly concluded that "the operations forwhich surgical mortality has been advocated as a quality indicator are not performed frequently enough to judge hospital quality."88

But the purpose of performance measurement is to protect the patient, not the physician or the hospital. Physicians who see many diabetics are more likely to develop the expertise needed to care for this complex, challenging disease. If quality datawere published, the low-volume physicians and hospitals that cannot generate statistically reliable data would likely lose their patients to those who are achieving excellent outcomes, in part because they see so many diabetics.

The Quality of Health Care Information

A serious but correctable objection is voiced by those who point outthat physicians and hospitals should not be held responsible for things they do not control.89 It is a correctable objection because there are industries that have a long history with management control systems, which are used to evaluate managers. These systems are designed to focus on those outcomes that managers control.90 Their experiences could be adapted to healthcare.

Others worry about the quality of the information. First, much of the language for measuring health care quality has yet to be defined. Second, the risk adjusters that would make it possible to compare the performance of high-risk specialists to those who treat less-severely-ill patients are not yet fully developed.91 Third, the raw data are flawed. For example, the federal government's data bank of the adverse actions taken against physicians and dentists has repeatedly been cited for severe flaws, including errors and substantial under-reporting of problems.92

These are substantial concerns. In the absence of solutions, the information will be seriously distorted. For example, a study that compared the rates of caesarean sections in hospitals, with and without adjustment for the fact that some hospitals might just have more patients prone to caesareans, found that adjustment caused the performance of a fourth of the hospitals in the study to change dramatically; among other changes, 10 percent of those originally classified as especially high or low users of these surgeries were reclassified as normal and some that were classified as normal were reclassified as having greater or lesser rates of surgery than the average.93 Physicians may also be dissuaded from caring for very sick patients if outcome measures do not correctly reflect the severity of illness. With imperfect adjustments, physicians will look much better if they care for only those patients who are more likely to recover from their illnesses.

Measurement issues like these are typically resolved with time and experience. The continual evolution in measures of performance of investment management—such as generally accepted accounting principles and beta, the measure of risk of different investments—provides an example. Beta has been continually refined since it was first suggested in 1952. Similarly, the system used by Morningstar to rate the investment performance of mutual funds evolved over time. For example, it was changed to allow for the difficulty of generating earnings in different types of investments. It now permits mutual funds operating in poorly performing sectors, say, technology, to earn high ratings if they performed substantially better than their peers, a form of risk adjustment.94

As the refinement of the measures of financial performance continued, investors had ever-better data with which to evaluate their mutual funds and stocks. Patients who put their health on the line deserve no less. The best way to improve the qualityof these data is not to suppress them, but rather, to open them to the public.

How Health Care Information Would Have Kept Jack Morgan Alive

Only a few words can make the difference between life and death in health care—a couple of words that compared how long Jack's HMO kept its patients waiting for a kidney transplant versus other insurers for patients with similar levels of illness in the same region. This information would have quickly identified his HMO's problems in managing its kidney transplant service. It is highly unlikely that Jack would have remained with the HMO if these data were regularly published and widely disseminated. These few words would have kept Jack Morgan alive.

Would Jack have read the information? Like the millions of Americans who access selected Internet sites, watch narrow niche TV like the Food Network, and read special-topic magazines and newspapers, Jack was an eager user of information that he found helpful. We know, for example, that to improve as a chef, he even taught himself French. To excel in his occupation, Jack continued to seek information on new cooking techniques, ingredients, and models of restaurant management. But he lacked the information about the quality of his health care provider that would have kept him alive.

To avoid Jack's fate, U.S. health care consumers must have the information that will enable them to shop intelligently for providers and treatment. They need and want it, and they have shown they will use it when it's available.95 By requiring the disclosure of audited financial information and its dissemination, the U.S. government's SEC has succeeded in providing such information to investors: our financial markets are lauded for their transparency and efficiency. The SEC's essential organizational characteristics—independence, focus on outcomes, reliance on private-sector analysts and auditors—should be replicated in a new government agency that will give newly empowered health care consumers the information they need.
