Impact of Weight Loss Drugs Underlines the Importance of Serendipity and Medical Entrepreneurship

The story of the creation of the weight loss drugs involves a fair amount of serendipity and medical entrepreneurship. A case has been made that we would have had these drugs 25 years sooner if Pfizer had not abandoned the development of their version due to the dauntingly huge costs of drug development. Recall that the largest component of those huge costs are the mandated Phase 3 randomized double-blind clinical trials.

Almost everyone now views these drugs as a major medical advance. The question is: how big? According to the reviewer quoted below, Dr. Eric Topol speculates: very big indeed. He raises the possibility that to improve lifespan and healthspan eventually most of us will be on one of these drugs.

If so then the weight loss drugs will be even more compelling examples of the importance of regulating so as to allow entrepreneurs to take quick advantage of serendipity. How many lives were lost that could have been saved, how much suffering was experienced that could have been avoided, if over-regulation by the F.D.A. had not delayed the availability of these drugs by 25 years?

(p. A13) More than half of American adults suffer from at least one chronic illness—most commonly diabetes, heart disease, cancer or neurodegeneration. By age 65, 80% are afflicted with two or more conditions. Among those fortunate enough to reach 80, it’s rare to find anyone who has arrived unscathed. In 2008 a group of scientists at the Scripps Research Institute in San Diego set out to recruit 1,400 of these healthy souls—known as the Wellderly—to figure out how they managed it.

Led by the cardiologist Eric Topol, the researchers hoped to identify the genetic factors associated with healthy aging. To their surprise, they found little in the DNA that stood out. They did, however, notice several striking traits. Compared with their peers, the disease-free subjects were generally thinner, exercised more frequently and seemed “remarkably upbeat,” often with rich social lives. These observations encouraged the research team to think about longevity (years of life) and healthspan (years of health) more broadly. In “Super Agers” Dr. Topol shares the results of this intellectual exploration.

. . .

Expensive new weight-loss drugs like Ozempic and Zepbound, Dr. Topol writes, have “extraordinary potential to promote health span.” In addition to stanching appetite, these drugs also seem to rapidly reduce harmful inflammation—an effect that “precedes and is independent of weight loss.” In the future, the author believes it’s “conceivable that most people will be taking” such medications, . . .

Correll Managed Georgia-Pacific Well and Then Used Those Skills to Save a Failing Hospital

In my Openness book, I make the case for the many benefits of an economic system of innovative dynamism. One of the lesser, but still important, benefits was first identified by Joseph Schumpeter. He argued for a spillover effect of innovative dynamism. The skills, knowledge, and technologies created by innovative entrepreneurs in the for-profit sector of the economy, are also applied and imitated in the nonprofit and government sectors. So where there is innovative dynamism, not only is the market more creative and efficient, but both the nonprofit and the government sectors are more creative and efficient.

A good example may be Pete Correll who acted entrepreneurially as CEO of Georgia-Pacific to bring more stability to the business by acquiring the James River Corporation, maker of Quilted Northern, and guided the Georgia-Pacific firm through years of lawsuits over asbestos. He eventually sold Georgia-Pacific to Koch Industries, Inc. My impression is that Charles Koch then applied his market-based management system to make the Georgia-Pacific part of his business much more efficient and innovative. [Query: does Koch’s achievement undermine my claim that Pete Correll had acted entrepreneurially in his earlier management of Georgia-Pacific? Or can both Correll and Koch have been good manager/entrepreneurs, but in different ways at different times?]

But according to his obituary in the WSJ, his greatest achievement may have been in taking over a near-bankrupt Atlanta public (aka government) hospital, reorganizing it from government to nonprofit, and modernizing its management and technology.

It May Take a “Thorny Character” to Be “Willing to Challenge Entire Establishment Belief Systems”

The obituary quoted below misidentifies Richard Bernstein’s main contribution. Yes, it is noteworthy that he was probably the first diabetes sufferer to effectively and continually monitor his own blood glucose level. But his main contribution was that by careful self-monitoring and trial-and-error experimentation he discovered that his health improved when he cutback on both carbs and insulin.

The obituary writer quotes Gary Taubes, but either didn’t read his book or disagrees with it, because Taubes is clear about Bernstein’s main contribution.

I am halfway through Taubes’s book. It is long and sometimes deep in the weeds, but comes highly recommended by Marty Makary and Siddhartha Mukherjee, both of whom I highly respect. The book sadly highlights how mainstream medicine can be very slow to reform clinical practice to new knowledge.

(p. C6) Richard Bernstein was flipping through a medical trade journal in 1969 when he saw an advertisement for a device that could check blood-sugar levels in one minute with one drop of blood. It was marketed to hospitals, not consumers, but Bernstein wanted one for himself. He had been sick his entire life and was worried he was running out of time.

. . .

Since he wasn’t a doctor, the manufacturer wouldn’t even sell him a device. So, he bought one under the name of his wife, Dr. Anne Bernstein, a psychiatrist.

He experimented with different doses of insulin and the frequency of shots. He eased off carbohydrates. He checked his blood sugar constantly to see how it was reacting.

After experimenting for several years, he figured out that if he maintained a low-carb diet, he didn’t need as much insulin and could avoid many of the wild swings in his blood-sugar levels. By checking his blood sugar throughout the day, he learned how to maintain normal levels. It changed his life.

. . .

With his diabetes under control, he tried to spread the word and change the way the disease is treated. In the early years, he was dismissed by much of the medical establishment. His ideas went against accepted wisdom and he was, after all, not a doctor. In 1979, at the age of 45, he enrolled at the Albert Einstein College of Medicine, where he received his M.D.

“I never wanted to be a doctor,” he told the New York Times in 1988. “But I had to become one to gain credibility.”

Bernstein went into private practice in Mamaroneck, N.Y., where he treated diabetics and continued to advocate for his ideas—to his patients, in articles, YouTube videos, letters to the editor, and writing books, including “Dr. Bernstein’s Diabetes Solution.”

. . .

Gary Taubes, the author of “Rethinking Diabetes,” said that it was Bernstein’s work that eventually led to the Diabetes Control and Complications Trial, a landmark study that demonstrated that diabetics could blunt the destructive effects of the disease by keeping their blood-sugar levels nearer normal. Released in 1993, the results led to the kind of self-monitoring and frequent shots of insulin that remains part of the standard treatment plan for Type 1 diabetes today—part of what Bernstein had been pushing for years.

This was only partial vindication for Bernstein. The medical establishment never fully embraced Bernstein or the strict low-carb diet that he prescribed, which some considered unrealistic.

Taubes said that Bernstein was a bit of a “thorny character” who was easy for the establishment to dislike. He also noted that’s something that comes with the territory when you spend your career telling people they’re wrong and you’re right.

“But often it’s the people who are not easy to like,” Taubes said, “who are the ones who are willing to challenge entire establishment belief systems.”

The Classical Liberal Economist’s Current Job: Minimize the Harm from Tariffs, Maximize the Benefits from Deregulation and Downsizing Government

I used to run into Richard Burkhauser at economics meetings occasionally and always enjoyed talking with him and hearing about his research. I believe Richard’s activity in the first Trump administration makes sense: if tariffs are going to be imposed, do them in a way that minimizes the damage to the economy. Although not mentioned in the article quoted below, I am sure Richard also did what he could to further the part of Trump’s agenda that was positive for he economy: reducing regulations so entrepreneurs can innovate and create jobs, and downsizing the government so taxpayers can keep more of their earnings.

(p. 1) Partway through a panel discussion at a recent economics conference in San Francisco, Jason Furman, a former adviser to President Barack Obama, turned to Kimberly Clausing, a former member of the Biden administration and the author of a book extolling the virtues of free trade.

“Everyone in this room agrees with your book,” Mr. Furman said. “No one outside of this room agrees with your book.”

The academics and policy wonks gathered in the hotel conference room laughed, but the comment captured something real: After decades of helping to shape policy on weighty matters like taxes and health insurance, economists find that their influence is at a low ebb.

. . .

(p. 6) Mr. Trump, in his first term, had few economists in top roles, and perhaps the most prominent exception — Peter Navarro, a Harvard-trained economist who was an adviser on trade policy — held skeptical views on trade, particularly with China, that put him far outside the economic mainstream. (In a 2016 survey of academic economists, not a single respondent said putting tariffs on China to encourage domestic production would be a good idea.)

Economists who held more mainstream views had limited influence. Richard Burkhauser, a Cornell University professor who served on Mr. Trump’s Council of Economic Advisers, said he and his colleagues quickly understood that there was little point in trying to talk Mr. Trump out of imposing tariffs.

“The most forlorn economists at the C.E.A. specialized in trade,” he said. If they had tried to fight tariffs, he said, “that would have been the last meeting we were at.”

Instead, Mr. Burkhauser said, economists focused on a different question: If the administration was going to impose tariffs, how could it do them in the least painful way possible?

Plenty in Science Still “Just Doesn’t Make Any Sense”

In my Openness book, I argue against those who see a future of inevitable stagnation. One argument for inevitable stagnation says that entrepreneurs build their innovations on science and we have run out of new knowledge to learn in science.

But whenever we keep our eyes open and observe more closely, or in new areas, we see what we cannot yet explain. The passages quoted below give another example. So we still have a lot to learn in science.

(Of course I also point out in the book that much entrepreneurial innovation is not tied to current advances in science–and is done by entrepreneurs who do not know, or who do not hold in high esteem, the current conclusions of mainstream scientists.)

(p. A14) On Dec. 24 [2024], NASA’s Parker Solar Probe swooped closer than it ever had before to the sun, just a few million miles above its blazing hot surface.

The team behind the mission waited nervously, trusting that the probe would survive the encounter. Then, a few minutes shy of midnight on Thursday [Dec. 2?, 2024], Parker phoned home.

. . .

. . ., there was some fear that the probe might not survive this time. Parker’s heat shield is designed so that the front of the vehicle can withstand facing the blistering heat of the sun’s outer atmosphere, which reaches millions of degrees, while the back, which contains the probe’s sensitive instruments, sits at a comfortable 85 degrees Fahrenheit.

“Literally one side is at a temperature that is unfathomable,” Joseph Westlake, the director of heliophysics at NASA, said. “And the back of it is a hot, sunny day.”

. . .

Parker’s data will . . . help scientists understand how the sun’s outer atmosphere, known as the corona, can be hundreds of times hotter than the solar surface below it.

“It’s like if you were standing next to a bonfire and you took a couple of steps back, and all of a sudden it got hotter,” Dr. Westlake said. “It just doesn’t make any sense.”

Medical Entrepreneur Fired for Nimbly Pivoting to Get Job Done

Back in early 2021, the Moderna vaccine was not yet widely available. Protocols mandated who could get the scarce shots, prioritizing health care workers, senior citizens, and those with severe diseases. Each vial contained enough for 10 doses, but the doses had to be given with six hours, before the vaccine spoiled. On Dec. 29 Dr. Hasan Gokal, a Pakistani immigrant, worked at the county’s first vaccination event, set up for health care workers. Near the end of the scheduled event a health care worker showed up and a nurse punctured a new vial to give the worker the shot.

Now, what to do with the remaining nine doses? He got on the phone and drove around seeking and finding several senior citizens who wanted the vaccine. Exhausted with a half-hour until the vaccine expired, he gave the final dose to his wife, who had pulmonary sarcoidosis, which was indicated in the protocols as a qualification for the vaccine.

Dr. Gokal’s supervisor and the director of human resources then fired Dr. Gokal:

The officials maintained that he had violated protocol and should have returned the remaining doses to the office or thrown them away, the doctor recalled. He also said that one of the officials startled him by questioning the lack of “equity” among those he had vaccinated.

“Are you suggesting that there were too many Indian names in that group?” Dr. Gokal said he asked.

Exactly, he said he was told. (Barry 2021, p. A5)

A couple of weeks later, the county district attorney charged Dr. Gokal with theft of doses of the vaccine.

Dr. Gokal acted as a medical entrepreneur. His job was to save lives by administering the vaccine. He nimbly pivoted in a difficult situation. For that he was punished–fired and charged with a crime.

The growing promulgation and enforcement of protocols limit physicians from acting as mission-oriented entrepreneurs. They are limited in their use of judgement based on their own experiences, they are limited in innovating, and sometimes they are even limited in using all of a scarce vaccine. These limits may be part of the reason that so many physicians today experience frustration and burn-out.

[As of the time of the writing of the NYT article cited below, Dr. Gokal remained fired from his job, and still was in legal jeopardy.]

My source for the facts of Dr. Gokal’s case, is the NYT article:

Gig Work Enables Free Agent Entrepreneurship

In my Openness book, I distinguish between free agent entrepreneurs and innovative entrepreneurs. Free agent entrepreneurs are there own boss, doing what has been done before. Innovative entrepreneurs are their own boss, doing what is new. Of course the distinction is not sharp–a continuum.

Recent research, summarized in the WSJ, suggests that gig work can ease entry into free agent entrepreneurship. Gig work is flexible–the gig worker has time when they need it, to work on their entrepreneurial venture. Gig work also can generate capital and give experience in self-management.

A higher percent of gig workers become entrepreneurs than similar employed workers, and they do so, on average, at a slightly younger age.

Those who want to regulate gig work, and thereby make it less common, should remember how gig work benefits aspiring entrepreneus.

If Switzerland Is “Capitalist to Its Core,” Where Are Its Breakthrough Innovations?

If Switzerland is the premier capitalist country in the world, as Ruchir Sharma argues in the puzzling passages quoted below, what breakthrough innovations has it nurtured in the last half century? I can think of none. (Swatch may have been successful, but was it a breakthrough?) If I am right, what is Switzerland missing?

(p. 5) Capitalist to its core, Switzerland imposes lighter taxes on individuals, consumers and corporations than the Scandinavian countries do. In 2018 its top income tax rate was the lowest in Western Europe at 36 percent, well below the Scandinavian average of 52 percent. Government spending amounts to a third of gross domestic product, compared with half in Scandinavia. And Switzerland is more open to trade, with a share of global exports around double that of any Scandinavian economy.

Streamlined government and open borders have helped make this landlocked, mountainous country an unlikely incubator of globally competitive companies. To build wealth, a country needs to make rich things, and an M.I.T. ranking of nations by the complexity of the products they export places Switzerland second behind Japan, well ahead of the Scandinavian countries, whose average rank is 15.

. . .

Die-hard admirers of Scandinavian socialism overlook the change of heart in countries such as Sweden, where heavy government spending led to the financial crises of the 1990s. Sweden responded by cutting the top income tax rate from nearly 90 percent to as low as 50 percent. Public spending fell from near 70 percent of G.D.P. to 50 percent. Growth revived, as the largest Scandinavian economy started to look more like Switzerland, streamlining government and leaving business more room to grow.

Innovative Project Entrepreneur Mike Wood Helped Children Leapfrog the Reading Skills Taught at School

In my Openness book I argue that the kind of entrepreneurs who matter most in changing the world are what I call “project entrepreneurs,” those who are on a mission to bring their project into the world. Mike Wood, discussed in the obituary quoted below was a project entrepreneur.

I sometimes wonder how much formal education would be desirable in a world, unlike our world, that lacked creeping credentialism. Samuel Smile’s biography of George Stephenson says that he had zero formal education, but early-on paid someone from his meagre wages in the mines, to teach him to read. After that, the inventor and innovative entrepreneur read prodigiously to became an exemplary autodidact.

Today, Stephenson could learn to read through phonics technology like the LeapFrog pads developed by Mike Wood.

[By the way, Mike Wood, like Danny Kahneman recently, committed suicide at Dignitis in Switzerland in anticipation of declining health, in Wood’s case Alzheimer’s. As a libertarian, I believe they had a right to do this, but were they right to exercise this right? Harvard psychology professor Daniel Gilbert cites (2006, pp. 166-168) research showing that people generally underestimate their resilience in the face of major health setbacks. They can often recalibrate to their new more limited capabilities, continuing to find challenges they find fulfilling to overcome. If so, then maybe Wood and Kahneman were wrong to exercise their right to end their lives. (More than most of my claims, I very readily admit this one could be wrong.)]

(p. A21) Mike Wood was a young father when his toddler’s struggles to read led him to develop one of a generation’s most fondly remembered toys.

Mr. Wood’s 3-year-old son, Mat, knew the alphabet but couldn’t pronounce the letter sounds. A lawyer in San Francisco, Mr. Wood had a new parent’s anxiety that if his child lagged as a reader, he would forever struggle in life.

So on his own time, Mr. Wood developed the prototype of an electronic toy that played sounds when children squeezed plastic letters. He based the idea on greeting cards that played a tune when opened.

Mr. Wood went on to found LeapFrog Enterprises, which in 1999 introduced the LeapPad, a child’s computer tablet that was a kind of talking book.

The LeapPad was a runaway hit, the best-selling toy of the 2000 holiday season, and LeapFrog became one of the fastest-growing toy companies in history.

. . .

Former colleagues recalled Mr. Wood as a demanding entrepreneur who was driven by a true belief that technology could help what he called “the LeapFrog generation” gain an educational leg up.

He had “famously fluffy hair,” Chris D’Angelo, LeapFrog’s former executive director of entertainment, wrote of Mr. Wood on The Bloom Report, a toy industry news site. “When stressed, he’d unconsciously rub his head — and the higher the hair, the higher the stakes. We (quietly) called them ‘high-hair days.’ It was funny, but also telling. He felt everything deeply — our work, our mission, our audience.”

. . .

A shift in reading pedagogy in the 1990s toward phonics — helping early readers make a connection between letters and sounds — drove interest in LeapFrog’s products among parents and teachers.

. . .

In 2023, his daughter-in-law, Emily Wood, posted a TikTok video of Mr. Wood teaching her daughter to use a forerunner of the LeapPad. The video received 391,000 likes and thousands of comments.

“I owe him my entire childhood,” one viewer wrote. “I spent hours on my LeapFrog with my ‘Scooby-Doo’ and ‘Shrek’ books.”

“I sell books now because of him,” another viewer wrote.

“I’m learning disabled and have a stutter,” wrote a third. “This man helped me learn to speak.”

“I’m 25 and I loved my LeapFrog,” a fourth commented. “Coming from an immigrant family, reading made me have so much imagination. I never stopped reading.”

Fraudulently Doctored Images and “Suspect Data” in Many Leading Cancer Research Papers

Charles Piller in his Doctored paints a damning picture of doctored images and suspect data rampant in the leading scientific literature on Alzheimer’s disease. Not only were leading scientists guilty of fraud, but the key institutions of scientific research (journals, universities, and government grant-making agencies) failing their oversight duty, and when outsiders stepped in to provide oversight, delayed and minimized their responses. Practicing and turning a blind eye to fraud matters, since Alzheimer’s patients are depending on this research. And researchers who do not commit fraud suffer because they appear to have worse research records than those compiled by the fraudsters. So the honest get worse academic appointments and fewer grants.

After reading Doctored I was depressed, but I at least hoped that this pathology was limited to this one (albeit an important one) area of medical research. But in the article quoted below, evidence is presented that there is substantial similar doctored images and suspect data in the field of cancer research.

A side issue in the quoted article is worth highlighting. In the absence of credible oversight from the institutions tasked with oversight, oversight is being done by competent volunteers, with the aid of A.I. These volunteers do not receive compensation for their work, and in fact are probably pay a price for it, since they alienate powerful scientists and scientific institutions. But if science is a search for truth, and truth matters for cures, they are doing a service to us all, and especially to those who suffer from major diseases such as Alsheimer’s and cancer.

On the connection with the Doctored book, it is worth noting that the article quotes Dr. Matthew Schrag, who is the most important source in Doctored. The article also quoted Elisabeth Bik, who does not have an MD like Schrag but has a PhD in microbiology, and who is another important source in Doctored.

(p. A1) The stomach cancer study was shot through with suspicious data. Identical constellations of cells were said to depict separate experiments on wholly different biological lineages. Photos of tumor-stricken mice, used to show that a drug reduced cancer growth, had been featured in two previous papers describing other treatments.

Problems with the study were severe enough that its publisher, after finding that the paper violated ethics guidelines, formally withdrew it within a few months of its publication in 2021. The study was then wiped from the internet, leaving behind a barren web page that said nothing about the reasons for its removal.

As it turned out, the flawed study was part of a pattern. Since 2008, two of its authors — Dr. Sam S. Yoon, chief of a cancer surgery division at Columbia University’s medical center, and a more junior cancer biologist — have collaborated with a rotating cast of researchers on a combined 26 articles that a British scientific sleuth has publicly flagged for containing suspect data. A medical journal retracted one of them this month after inquiries from The New York Times.

Memorial Sloan Kettering Cancer Center, where Dr. Yoon worked when much of the research was done, is now investigating the studies. Columbia’s medical center declined to comment on specific allegations, saying only that it reviews “any concerns about scientific integrity brought to our attention.”

Dr. Yoon, who has said his research could lead to better cancer treatments, did not answer repeated questions. Attempts to speak to the other researcher, Changhwan Yoon, an associate research scientist at Columbia, were also unsuccessful.

The allegations were aired in recent months in online comments on a science forum and in a blog post by Sholto David, an independent molecular biologist. He has ferreted out problems in a raft of high-profile cancer research, including dozens of papers at a Harvard cancer center that were subsequently referred for retractions or corrections.

From his flat in Wales, Dr. David pores over published images of cells, tumors and mice in his spare (p. A17) time and then reports slip-ups, trying to close the gap between people’s regard for academic research and the sometimes shoddier realities of the profession.

. . .

Armed with A.I.-powered detection tools, scientists and bloggers have recently exposed a growing body of such questionable research, like the faulty papers at Harvard’s Dana-Farber Cancer Institute and studies by Stanford’s president that led to his resignation last year.

But those high-profile cases were merely the tip of the iceberg, experts said. A deeper pool of unreliable research has gone unaddressed for years, shielded in part by powerful scientific publishers driven to put out huge volumes of studies while avoiding the reputational damage of retracting them publicly.

The quiet removal of the 2021 stomach cancer study from Dr. Yoon’s lab, a copy of which was reviewed by The Times, illustrates how that system of scientific publishing has helped enable faulty research, experts said. In some cases, critical medical fields have remained seeded with erroneous studies.

“The journals do the bare minimum,” said Elisabeth Bik, a microbiologist and image expert who described Dr. Yoon’s papers as showing a worrisome pattern of copied or doctored data. “There’s no oversight.”

. . .

Dr. Yoon, a stomach cancer specialist and a proponent of robotic surgery, kept climbing the academic ranks, bringing his junior researcher along with him. In September 2021, around the time the study was published, he joined Columbia, which celebrated his prolific research output in a news release. His work was financed in part by half a million dollars in federal research money that year, adding to a career haul of nearly $5 million in federal funds.

. . .

The researchers’ suspicious publications stretch back 16 years. Over time, relatively minor image copies in papers by Dr. Yoon gave way to more serious discrepancies in studies he collaborated on with Changhwan Yoon, Dr. David said. The pair, who are not related, began publishing articles together around 2013.

But neither their employers nor their publishers seemed to start investigating their work until this past fall, when Dr. David published his initial findings on For Better Science, a blog, and notified Memorial Sloan Kettering, Columbia and the journals. Memorial Sloan Kettering said it began its investigation then.

. . .

A proliferation of medical journals, they said, has helped fuel demand for ever more research articles. But those same journals, many of them operated by multibillion-dollar publishing companies, often respond slowly or do nothing at all once one of those articles is shown to contain copied data. Journals retract papers at a fraction of the rate at which they publish ones with problems.

. . .

“There are examples in this set that raise pretty serious red flags for the possibility of misconduct,” said Dr. Matthew Schrag, a Vanderbilt University neurologist who commented as part of his outside work on research integrity.

. . .

Experts said the handling of the article was symptomatic of a tendency on the part of scientific publishers to obscure reports of lapses.

“This is typical, sweeping-things-under-the-rug kind of nonsense,” said Dr. Ivan Oransky, co-founder of Retraction Watch, which keeps a database of 47,000-plus retracted papers. “This is not good for the scientific record, to put it mildly.”

Rampant Fraud in ‘Skin’ Bandages Paid by Medicare

A “quirk” in the Medicare law allows ‘skin’ bandage firms to charge, and have Medicare pay them, exorbitant prices. Are such quirks accidents or intentional? Medicare rules are so voluminous and obscure that few have an incentive to look carefully at the details. But the firms selling ‘skin’ bandages had an incentive. Entrepreneurs within these firms saw an opportunity and seized it. But they are what William Baumol called “destructive entrepreneurs.” Their energy and talent works against the general good.

Since patients are not paying, they have little incentive to reveal the fraud. So the taxpayers are robbed. In a system where the patients are the payers they would have an incentive to reveal fraud, and to seek alternatives to over-priced medical therapies.

But what of the poor, you ask? Susan Feigenbaum proposed an insurance system where patients would receive lump sum payments for different ailments. Then poor patients could be payers, and have the incentives of payer.

(p. 1) Seniors across the country are wearing very expensive bandages.

Made of dried bits of placenta, the paper-thin patches cover stubborn wounds and can cost thousands of dollars per square inch.

Some research has found that such “skin substitutes” help certain wounds heal. But in the past few years, dozens of unstudied and costly products have flooded the market.

Bandage companies set ever-rising prices for new brands of the products, taking advantage of a loophole in Medicare rules, The New York Times found. Some doctors then buy the coverings at large discounts but charge Medicare the full sticker price, pocketing the difference.

Partly because of these financial incentives, many patients receive the bandages who do not need them. The result, experts said, is one of the largest examples of Medicare waste in history.

Private insurers rarely pay for skin substitutes, arguing that they are unproven and unnecessary. But Medicare, the government insurance program for seniors, routinely covers them. Spending on skin substitutes exceeded $10 billion in 2024, more than double the figure in 2023, according to an analysis of Medicare data done for The Times by Early Read, a firm that evaluates costs for large health companies.

Medicare now spends more on the bandages than on ambulance rides, anesthesia or CT scans, the analysis found.

(p. 19) . . . experts in health care costs said the spike had been driven . . . by sellers and doctors taking advantage of Medicare’s pricing rules. The government will reimburse any price that a company sets for brand-new skin substitutes, even if it is far above the market average. The higher the price, the larger the doctors’ cut.

And the bigger the bandage, the more they can charge. For one patient in Nevada, Medicare spent $14 million on skin substitutes over the course of a year, according to billing records reviewed by The Times. The wound of a patient in Washington State persisted after Medicare paid $6 million for the coverings. A man in Texas got $1.3 million of bandages despite having no wound at all. Health executives trying to ferret out suspicious spending identified these patients and shared their stories with The Times.

As the Trump administration — and particularly the new Department of Government Efficiency run by Elon Musk — aims to shrink the federal purse, profligate Medicare spending is a ripe target, experts said.

Companies have billed Medicare for hundreds of thousands of urinary catheters that doctors never ordered. Other schemes have peddled urine tests and knee braces. In 2023, a federal watchdog agency flagged skin substitute spending as wasteful for both taxpayers and Medicare enrollees, who ultimately pay the costs with higher premiums.

“It’s the patients, it’s the taxpayers — unfortunately everyone is footing a part of the bill for this outsized spend,” said Dana Rye, an executive with Duly Health and Care, a Chicago-based medical group where payments for skin substitutes have risen 1,400 percent since 2022.

. . .

Five years ago, the most expensive skin substitute cost $1,042 per square inch, while some were as cheap as $45. Today, the three most expensive products on the market each cost more than $21,000. (Samaritan Biologics, a company in Memphis that sells the three products, did not answer questions about why they cost so much.)

Companies can set such high prices because of a quirk in Medicare pricing rules, industry experts said. For the first six months of a new bandage product’s life, Medicare will set the reimbursement rate at whatever price a company chooses. After that, the agency adjusts the reimbursement to reflect the actual price paid by doctors after any discounts.

To circumvent the reimbursement drop, some companies simply roll out new products.

In April 2023, Medicare began reimbursing $6,497 for every square inch of a bandage called Zenith, sold by Legacy Medical Consultants, a company in Fort Worth, Texas. Six months later, Zenith’s reimbursement fell to $2,746.

That month, October 2023, Medicare began reimbursing $6,490 for a new Legacy product, a “dual layer” bandage called Impax.

Marketing materials for the two products use identical photographs and similar language. The company describes both products as providing “optimal wound covering and protection during the treatment of wounds.”

Since 2022, spending on Zenith and Impax has exceeded $2.6 billion, according to Early Read’s analysis.

. . .

A cottage industry of doctors and nurses make house calls to treat wounds. Some skin substitute companies pitch themselves to wound care doctors by offering a cut of the rising bandage prices.

Dr. Caroline Fife, a wound care doctor from Texas who often writes about industry excesses, shared on her blog last year an email she received from an undisclosed skin substitute company. The company boasted that other doctors had developed “a healthy revenue stream” from its bandages and that a patch smaller than a credit card “would generate a little over $20,000 for your practice.”

Some companies offer doctors a “bulk discount” of up to 45 percent, according to doctor interviews and contracts reviewed by The Times. But doctors then collect a Medicare reimbursement for the full price of the product.
