The Cost Conundrum: What A Texas Town Can Teach Us About Health Care, Part 1.

The Cost Conundrum:
What a Texas town can teach us about health care.
by Atul Gawande

It is spring in McAllen, Texas. The morning sun is warm. The streets are lined with palm trees and pickup trucks. McAllen is in Hidalgo County, which has the lowest household income in the country, but it’s a border town, and a thriving foreign-trade zone has kept the unemployment rate below ten per cent. McAllen calls itself the Square Dance Capital of the World. “Lonesome Dove” was set around here.

McAllen has another distinction, too: it is one of the most expensive health-care markets in the country. Only Miami—which has much higher labor and living costs—spends more per person on health care. In 2006, Medicare spent fifteen thousand dollars per enrollee here, almost twice the national average. The income per capita is twelve thousand dollars. In other words, Medicare spends three thousand dollars more per person here than the average person earns.

The explosive trend in American medical costs seems to have occurred here in an especially intense form. Our country’s health care is by far the most expensive in the world. In Washington, the aim of health-care reform is not just to extend medical coverage to everybody but also to bring costs under control. Spending on doctors, hospitals, drugs, and the like now consumes more than one of every six dollars we earn. The financial burden has damaged the global competitiveness of American businesses and bankrupted millions of families, even those with insurance. It’s also devouring our government. “The greatest threat to America’s fiscal health is not Social Security,” President Barack Obama said in a March speech at the White House. “It’s not the investments that we’ve made to rescue our economy during this crisis. By a wide margin, the biggest threat to our nation’s balance sheet is the skyrocketing cost of health care. It’s not even close.”

The question we’re now frantically grappling with is how this came to be, and what can be done about it. McAllen, Texas, the most expensive town in the most expensive country for health care in the world, seemed a good place to look for some answers.

From the moment I arrived, I asked almost everyone I encountered about McAllen’s health costs—a businessman I met at the five-gate McAllen-Miller International Airport, the desk clerks at the Embassy Suites Hotel, a police-academy cadet at McDonald’s. Most weren’t surprised to hear that McAllen was an outlier. “Just look around,” the cadet said. “People are not healthy here.” McAllen, with its high poverty rate, has an incidence of heavy drinking sixty per cent higher than the national average. And the Tex-Mex diet has contributed to a thirty-eight-per-cent obesity rate.

One day, I went on rounds with Lester Dyke, a weather-beaten, ranch-owning fifty-three-year-old cardiac surgeon who grew up in Austin, did his surgical training with the Army all over the country, and settled into practice in Hidalgo County. He has not lacked for business: in the past twenty years, he has done some eight thousand heart operations, which exhausts me just thinking about it. I walked around with him as he checked in on ten or so of his patients who were recuperating at the three hospitals where he operates. It was easy to see what had landed them under his knife. They were nearly all obese or diabetic or both. Many had a family history of heart disease. Few were taking preventive measures, such as cholesterol-lowering drugs, which, studies indicate, would have obviated surgery for up to half of them.

Yet public-health statistics show that cardiovascular-disease rates in the county are actually lower than average, probably because its smoking rates are quite low. Rates of asthma, H.I.V., infant mortality, cancer, and injury are lower, too. El Paso County, eight hundred miles up the border, has essentially the same demographics. Both counties have a population of roughly seven hundred thousand, similar public-health statistics, and similar percentages of non-English speakers, illegal immigrants, and the unemployed. Yet in 2006 Medicare expenditures (our best approximation of over-all spending patterns) in El Paso were $7,504 per enrollee—half as much as in McAllen. An unhealthy population couldn’t possibly be the reason that McAllen’s health-care costs are so high. (Or the reason that America’s are. We may be more obese than any other industrialized nation, but we have among the lowest rates of smoking and alcoholism, and we are in the middle of the range for cardiovascular disease and diabetes.)

Was the explanation, then, that McAllen was providing unusually good health care? I took a walk through Doctors Hospital at Renaissance, in Edinburg, one of the towns in the McAllen metropolitan area, with Robert Alleyn, a Houston-trained general surgeon who had grown up here and returned home to practice. The hospital campus sprawled across two city blocks, with a series of three- and four-story stucco buildings separated by golfing-green lawns and black asphalt parking lots. He pointed out the sights—the cancer center is over here, the heart center is over there, now we’re coming to the imaging center. We went inside the surgery building. It was sleek and modern, with recessed lighting, classical music piped into the waiting areas, and nurses moving from patient to patient behind rolling black computer pods. We changed into scrubs and Alleyn took me through the sixteen operating rooms to show me the laparoscopy suite, with its flat-screen video monitors, the hybrid operating room with built-in imaging equipment, the surgical robot for minimally invasive robotic surgery.

I was impressed. The place had virtually all the technology that you’d find at Harvard and Stanford and the Mayo Clinic, and, as I walked through that hospital on a dusty road in South Texas, this struck me as a remarkable thing. Rich towns get the new school buildings, fire trucks, and roads, not to mention the better teachers and police officers and civil engineers. Poor towns don’t. But that rule doesn’t hold for health care.

At McAllen Medical Center, I saw an orthopedic surgeon work under an operating microscope to remove a tumor that had wrapped around the spinal cord of a fourteen-year-old. At a home-health agency, I spoke to a nurse who could provide intravenous-drug therapy for patients with congestive heart failure. At McAllen Heart Hospital, I watched Dyke and a team of six do a coronary-artery bypass using technologies that didn’t exist a few years ago. At Renaissance, I talked with a neonatologist who trained at my hospital, in Boston, and brought McAllen new skills and technologies for premature babies. “I’ve had nurses come up to me and say, ‘I never knew these babies could survive,’ ” he said.

And yet there’s no evidence that the treatments and technologies available at McAllen are better than those found elsewhere in the country. The annual reports that hospitals file with Medicare show that those in McAllen and El Paso offer comparable technologies—neonatal intensive-care units, advanced cardiac services, PET scans, and so on. Public statistics show no difference in the supply of doctors. Hidalgo County actually has fewer specialists than the national average.

Nor does the care given in McAllen stand out for its quality. Medicare ranks hospitals on twenty-five metrics of care. On all but two of these, McAllen’s five largest hospitals performed worse, on average, than El Paso’s. McAllen costs Medicare seven thousand dollars more per person each year than does the average city in America. But not, so far as one can tell, because it’s delivering better health care.

One night, I went to dinner with six McAllen doctors. All were what you would call bread-and-butter physicians: busy, full-time, private-practice doctors who work from seven in the morning to seven at night and sometimes later, their waiting rooms teeming and their desks stacked with medical charts to review.

Some were dubious when I told them that McAllen was the country’s most expensive place for health care. I gave them the spending data from Medicare. In 1992, in the McAllen market, the average cost per Medicare enrollee was $4,891, almost exactly the national average. But since then, year after year, McAllen’s health costs have grown faster than any other market in the country, ultimately soaring by more than ten thousand dollars per person.

“Maybe the service is better here,” the cardiologist suggested. People can be seen faster and get their tests more readily, he said.

Others were skeptical. “I don’t think that explains the costs he’s talking about,” the general surgeon said.

“It’s malpractice,” a family physician who had practiced here for thirty-three years said.

“McAllen is legal hell,” the cardiologist agreed. Doctors order unnecessary tests just to protect themselves, he said. Everyone thought the lawyers here were worse than elsewhere.

That explanation puzzled me. Several years ago, Texas passed a tough malpractice law that capped pain-and-suffering awards at two hundred and fifty thousand dollars. Didn’t lawsuits go down?

“Practically to zero,” the cardiologist admitted.

“Come on,” the general surgeon finally said. “We all know these arguments are bullshit. There is overutilization here, pure and simple.” Doctors, he said, were racking up charges with extra tests, services, and procedures.

The surgeon came to McAllen in the mid-nineties, and since then, he said, “the way to practice medicine has changed completely. Before, it was about how to do a good job. Now it is about ‘How much will you benefit?’ ”

Everyone agreed that something fundamental had changed since the days when health-care costs in McAllen were the same as those in El Paso and elsewhere. Yes, they had more technology. “But young doctors don’t think anymore,” the family physician said.

The surgeon gave me an example. General surgeons are often asked to see patients with pain from gallstones. If there aren’t any complications—and there usually aren’t—the pain goes away on its own or with pain medication. With instruction on eating a lower-fat diet, most patients experience no further difficulties. But some have recurrent episodes, and need surgery to remove their gallbladder.

Seeing a patient who has had uncomplicated, first-time gallstone pain requires some judgment. A surgeon has to provide reassurance (people are often scared and want to go straight to surgery), some education about gallstone disease and diet, perhaps a prescription for pain; in a few weeks, the surgeon might follow up. But increasingly, I was told, McAllen surgeons simply operate. The patient wasn’t going to moderate her diet, they tell themselves. The pain was just going to come back. And by operating they happen to make an extra seven hundred dollars.

I gave the doctors around the table a scenario. A forty-year-old woman comes in with chest pain after a fight with her husband. An EKG is normal. The chest pain goes away. She has no family history of heart disease. What did McAllen doctors do fifteen years ago?

Send her home, they said. Maybe get a stress test to confirm that there’s no issue, but even that might be overkill.

And today? Today, the cardiologist said, she would get a stress test, an echocardiogram, a mobile Holter monitor, and maybe even a cardiac catheterization.

“Oh, she’s definitely getting a cath,” the internist said, laughing grimly.

To determine whether overuse of medical care was really the problem in McAllen, I turned to Jonathan Skinner, an economist at Dartmouth’s Institute for Health Policy and Clinical Practice, which has three decades of expertise in examining regional patterns in Medicare payment data. I also turned to two private firms—D2Hawkeye, an independent company, and Ingenix, UnitedHealthcare’s data-analysis company—to analyze commercial insurance data for McAllen. The answer was yes. Compared with patients in El Paso and nationwide, patients in McAllen got more of pretty much everything—more diagnostic testing, more hospital treatment, more surgery, more home care.

The Medicare payment data provided the most detail. Between 2001 and 2005, critically ill Medicare patients received almost fifty per cent more specialist visits in McAllen than in El Paso, and were two-thirds more likely to see ten or more specialists in a six-month period. In 2005 and 2006, patients in McAllen received twenty per cent more abdominal ultrasounds, thirty per cent more bone-density studies, sixty per cent more stress tests with echocardiography, two hundred per cent more nerve-conduction studies to diagnose carpal-tunnel syndrome, and five hundred and fifty per cent more urine-flow studies to diagnose prostate troubles. They received one-fifth to two-thirds more gallbladder operations, knee replacements, breast biopsies, and bladder scopes. They also received two to three times as many pacemakers, implantable defibrillators, cardiac-bypass operations, carotid endarterectomies, and coronary-artery stents. And Medicare paid for five times as many home-nurse visits. The primary cause of McAllen’s extreme costs was, very simply, the across-the-board overuse of medicine.

This is a disturbing and perhaps surprising diagnosis. Americans like to believe that, with most things, more is better. But research suggests that where medicine is concerned it may actually be worse. For example, Rochester, Minnesota, where the Mayo Clinic dominates the scene, has fantastically high levels of technological capability and quality, but its Medicare spending is in the lowest fifteen per cent of the country—$6,688 per enrollee in 2006, which is eight thousand dollars less than the figure for McAllen. Two economists working at Dartmouth, Katherine Baicker and Amitabh Chandra, found that the more money Medicare spent per person in a given state the lower that state’s quality ranking tended to be. In fact, the four states with the highest levels of spending—Louisiana, Texas, California, and Florida—were near the bottom of the national rankings on the quality of patient care.

In a 2003 study, another Dartmouth team, led by the internist Elliott Fisher, examined the treatment received by a million elderly Americans diagnosed with colon or rectal cancer, a hip fracture, or a heart attack. They found that patients in higher-spending regions received sixty per cent more care than elsewhere. They got more frequent tests and procedures, more visits with specialists, and more frequent admission to hospitals. Yet they did no better than other patients, whether this was measured in terms of survival, their ability to function, or satisfaction with the care they received. If anything, they seemed to do worse.

That’s because nothing in medicine is without risks. Complications can arise from hospital stays, medications, procedures, and tests, and when these things are of marginal value the harm can be greater than the benefits. In recent years, we doctors have markedly increased the number of operations we do, for instance. In 2006, doctors performed at least sixty million surgical procedures, one for every five Americans. No other country does anything like as many operations on its citizens. Are we better off for it? No one knows for sure, but it seems highly unlikely. After all, some hundred thousand people die each year from complications of surgery—far more than die in car crashes.

To make matters worse, Fisher found that patients in high-cost areas were actually less likely to receive low-cost preventive services, such as flu and pneumonia vaccines, faced longer waits at doctor and emergency-room visits, and were less likely to have a primary-care physician. They got more of the stuff that cost more, but not more of what they needed.

In an odd way, this news is reassuring. Universal coverage won’t be feasible unless we can control costs. Policymakers have worried that doing so would require rationing, which the public would never go along with. So the idea that there’s plenty of fat in the system is proving deeply attractive. “Nearly thirty per cent of Medicare’s costs could be saved without negatively affecting health outcomes if spending in high- and medium-cost areas could be reduced to the level in low-cost areas,” Peter Orszag, the President’s budget director, has stated.

Most Americans would be delighted to have the quality of care found in places like Rochester, Minnesota, or Seattle, Washington, or Durham, North Carolina—all of which have world-class hospitals and costs that fall below the national average. If we brought the cost curve in the expensive places down to their level, Medicare’s problems (indeed, almost all the federal government’s budget problems for the next fifty years) would be solved. The difficulty is how to go about it. Physicians in places like McAllen behave differently from others. The $2.4-trillion question is why. Unless we figure it out, health reform will fail.

I had what I considered to be a reasonable plan for finding out what was going on in McAllen. I would call on the heads of its hospitals, in their swanky, decorator-designed, churrigueresco offices, and I’d ask them.

The first hospital I visited, McAllen Heart Hospital, is owned by Universal Health Services, a for-profit hospital chain with headquarters in King of Prussia, Pennsylvania, and revenues of five billion dollars last year. I went to see the hospital’s chief operating officer, Gilda Romero. Truth be told, her office seemed less churrigueresco than Office Depot. She had straight brown hair, sympathetic eyes, and looked more like a young school teacher than like a corporate officer with nineteen years of experience. And when I inquired, “What is going on in this place?” she looked surprised.

Is McAllen really that expensive? she asked.

I described the data, including the numbers indicating that heart operations and catheter procedures and pacemakers were being performed in McAllen at double the usual rate.

“That is interesting,” she said, by which she did not mean, “Uh-oh, you’ve caught us” but, rather, “That is actually interesting.” The problem of McAllen’s outlandish costs was new to her. She puzzled over the numbers. She was certain that her doctors performed surgery only when it was necessary. It had to be one of the other hospitals. And she had one in mind—Doctors Hospital at Renaissance, the hospital in Edinburg that I had toured.

She wasn’t the only person to mention Renaissance. It is the newest hospital in the area. It is physician-owned. And it has a reputation (which it disclaims) for aggressively recruiting high-volume physicians to become investors and send patients there. Physicians who do so receive not only their fee for whatever service they provide but also a percentage of the hospital’s profits from the tests, surgery, or other care patients are given. (In 2007, its profits totalled thirty-four million dollars.) Romero and others argued that this gives physicians an unholy temptation to overorder.

Such an arrangement can make physician investors rich. But it can’t be the whole explanation. The hospital gets barely a sixth of the patients in the region; its margins are no bigger than the other hospitals’—whether for profit or not for profit—and it didn’t have much of a presence until 2004 at the earliest, a full decade after the cost explosion in McAllen began.

“Those are good points,” Romero said. She couldn’t explain what was going on.

The following afternoon, I visited the top managers of Doctors Hospital at Renaissance. We sat in their boardroom around one end of a yacht-length table. The chairman of the board offered me a soda. The chief of staff smiled at me. The chief financial officer shook my hand as if I were an old friend. The C.E.O., however, was having a hard time pretending that he was happy to see me. Lawrence Gelman was a fifty-seven-year-old anesthesiologist with a Bill Clinton shock of white hair and a weekly local radio show tag-lined “Opinions from an Unrelenting Conservative Spirit.” He had helped found the hospital. He barely greeted me, and while the others were trying for a how-can-I-help-you-today attitude, his body language was more let’s-get-this-over-with.

So I asked him why McAllen’s health-care costs were so high. What he gave me was a disquisition on the theory and history of American health-care financing going back to Lyndon Johnson and the creation of Medicare, the upshot of which was: (1) Government is the problem in health care. “The people in charge of the purse strings don’t know what they’re doing.” (2) If anything, government insurance programs like Medicare don’t pay enough. “I, as an anesthesiologist, know that they pay me ten per cent of what a private insurer pays.” (3) Government programs are full of waste. “Every person in this room could easily go through the expenditures of Medicare and Medicaid and see all kinds of waste.” (4) But not in McAllen. The clinicians here, at least at Doctors Hospital at Renaissance, “are providing necessary, essential health care,” Gelman said. “We don’t invent patients.”

Then why do hospitals in McAllen order so much more surgery and scans and tests than hospitals in El Paso and elsewhere?

In the end, the only explanation he and his colleagues could offer was this: The other doctors and hospitals in McAllen may be overspending, but, to the extent that his hospital provides costlier treatment than other places in the country, it is making people better in ways that data on quality and outcomes do not measure.

“Do we provide better health care than El Paso?” Gelman asked. “I would bet you two to one that we do.”

It was a depressing conversation—not because I thought the executives were being evasive but because they weren’t being evasive. The data on McAllen’s costs were clearly new to them. They were defending McAllen reflexively. But they really didn’t know the big picture of what was happening.

And, I realized, few people in their position do. Local executives for hospitals and clinics and home-health agencies understand their growth rate and their market share; they know whether they are losing money or making money. They know that if their doctors bring in enough business—surgery, imaging, home-nursing referrals—they make money; and if they get the doctors to bring in more, they make more. But they have only the vaguest notion of whether the doctors are making their communities as healthy as they can, or whether they are more or less efficient than their counterparts elsewhere. A doctor sees a patient in clinic, and has her check into a McAllen hospital for a CT scan, an ultrasound, three rounds of blood tests, another ultrasound, and then surgery to have her gallbladder removed. How is Lawrence Gelman or Gilda Romero to know whether all that is essential, let alone the best possible treatment for the patient? It isn’t what they are responsible or accountable for.

Health-care costs ultimately arise from the accumulation of individual decisions doctors make about which services and treatments to write an order for. The most expensive piece of medical equipment, as the saying goes, is a doctor’s pen. And, as a rule, hospital executives don’t own the pen caps. Doctors do.

If doctors wield the pen, why do they do it so differently from one place to another? Brenda Sirovich, another Dartmouth researcher, published a study last year that provided an important clue. She and her team surveyed some eight hundred primary-care physicians from high-cost cities (such as Las Vegas and New York), low-cost cities (such as Sacramento and Boise), and others in between. The researchers asked the physicians specifically how they would handle a variety of patient cases. It turned out that differences in decision-making emerged in only some kinds of cases. In situations in which the right thing to do was well established—for example, whether to recommend a mammogram for a fifty-year-old woman (the answer is yes)—physicians in high- and low-cost cities made the same decisions. But, in cases in which the science was unclear, some physicians pursued the maximum possible amount of testing and procedures; some pursued the minimum. And which kind of doctor they were depended on where they came from.
