Much Health Spending “Does Nothing to Improve Our Health”

(p. C5) Fortunately — if that’s the right word — there is an obvious candidate for cost-cutting: all that care that brings no health benefit. It’s not hard to find examples. Scientific studies have shown that many treatments, including spinal fusion, routine episiotomies and neonatal intensive care, are overdone. These procedures often help specific subsets of patients. But for a lot of people, and “Overtreated” is full of stories, the treatments are a modern-day version of bloodletting.
“We spend between one fifth and one third of our health care dollars,” writes Ms. Brownlee, a senior fellow at the New America Foundation and former writer for U.S. News & World Report, “on care that does nothing to improve our health.”
Worst of all, overtreatment often causes harm, because even the safest procedures bring some risk. One study found that a group of Medicare patients admitted to high-spending hospitals were 2 to 6 percent more likely to die than a group admitted to more conservative hospitals.

Non-Market Health Care Pricing Results in Health Care Shortages


(p. A22) When my Labrador retriever became acutely lame, we were able to locate a veterinary orthopedic expert in Atlanta within 48 hours who was able to repair a ruptured tendon within one week. But my prospects of identifying an endocrinologist who can care for my daughter’s diabetes when she turns 18 are much less promising.
The limited number of endocrine specialists is a not a consequence of limited demand — everyone is aware of the epidemic of diabetes we are facing. There are also shortages of generalists and other specialists, and the reason is the absence of market signals — i.e., market-based prices — for influencing the supply of physicians in various specialties.
The roots of this problem lay in the use of administrative pricing structures in medicine. The way prices are set in health care already distorts the appropriate allocation of efforts and resources in health care today. Unfortunately, many of the suggested reforms of our health care system — including the various plans for universal care, or universal insurance, or a single-payer system, that various policy makers and Democratic presidential candidates espouse — rest on the same unsound foundations, and will produce more of the same.
. . .
One important lesson of the 20th century is that, while markets are far from perfect, more choices are available when people are able to use free markets to interact with each other. Markets may not get the prices exactly correct all the time, but they are capable of self- correction, a capacity that has yet to be demonstrated by administrative pricing.
It tells you something when the supply of and demand for specialist veterinary care is so easily matched when the prices of these services are established on the market — while shortages and oversupplies are common for human medical care when the prices of these services are set by administrators in the public sector. Will health-care reformers — and American citizens — get the message?

Entrepreneurial Medicine Hunter Seeks Cures in Ethnobotany

(p. C1) Part David Attenborough, part Indiana Jones, Mr. Kilham, an ethnobotanist from Massachusetts who calls himself the Medicine Hunter, has scoured remote jungles and highlands for three decades for plants, oils and extracts that can heal. He has eaten bees and scorpions in China, fired blow guns with Amazonian natives, and learned traditional war dances from Pacific Islanders.
But behind the colorful tales lies the prospect of money, lots of money — for Western pharmaceutical companies, impoverished indigenous tribes and Mr. Kilham.
. . .
(p. C5) In Peru, Mr. Kilham is betting on maca, a small root vegetable that grows here in the central highlands — “a turnip that packs a punch,” he says, adding “it imparts energy, sex drive and stamina like nothing else.”
That view is supported by studies carried out at the International Potato Center, a Lima-based research center that is internationally financed and staffed. Studies there show maca improves stamina, reduces the risk of prostate cancer and increases the motility, volume and quality of sperm.
Some peer reviewed studies published in the journal Reproductive Biology and Endocrinology backed up those findings.
. . .
One product, Maca Stimulant, is sold in Wal-Mart under Mr. Kilham’s Medicine Hunter brand. Mr. Kilham earns a retainer from both Naturex and Enzymatic Therapy, in addition to royalties from another Medicine Hunter-branded product at Wal-Mart.
Mr. Kilham says he earns around $200,000 each year in retainers, and sales are so buoyant he expects to make “in the mid-six figures” in royalties next year.
Mr. Kilham insists he is not in the business simply for financial gain. His motivation comes from promoting herbal medicines and helping traditional communities, he said.
“I have financial security and don’t need to make money from this,” he said. “I believe trade is the best way to get good medicines to the public, to help the environment and to help indigenous people.”
He and Mr. Cam pay growers here in Ninacaca a premium of 6 soles (about $2) for a kilo of maca, almost twice the going rate of 3 to 3.40 soles a kilo. They have set up a computer room at the Chakarunas warehouse and a free dental clinic, the town’s first.
Mr. Kilham is clearly adored by the locals in these desolate, wind-swept villages. On a recent visit here, shamans, maca growers and their families flocked to him. Since only maca and potatoes grow at this altitude, they are thankful Mr. Kilham is helping them sell their produce.

The Danger of “Misconceived Pessimism”


In the full version of the commentary quoted below, the authors mention four lines of research that they believe hold promise for the future: vaccines, epigenetics, targeted therapies, and cancer “stem cells.”

(p. A17) This week, the National Cancer Institute, in conjunction with other organizations that track cancers, reported that the death rate from cancer declined from 2002-2004 by an average of 2.1% per year. This is an improvement over the 1.1% annual declines from 1993-2002 and is very good news indeed. Each 1% decline represents 5,000 people living rather than dying, and, of course, this figure is compounded each year.
While some part of the declining death rate from cancer is the consequence of screening, much is the result of greatly improved treatments. And we believe that the successes achieved to date are only the modest beginning of a revolution in the research into and treatment of cancer.
During the last half of the 20th century, almost all treatments of cancers involved forms of chemotherapy in which cancerous and normal tissues were bombarded with nonselective cytoxic drugs. These drugs killed all cells, healthy as well as malignant. Worse, they did not kill all cancer cells, so the cancer progressed — leading to the pessimism dominant in people’s minds today, a reflection of years of articles and opinion pieces in the popular press expressing the view that “the war on cancer” has been waged incorrectly, if not lost.
Now, however, new therapeutic modes are in play, based on better understandings of cancers and great advances in technologies.
. . .
The danger is that misconceived pessimism might result in a loss of popular moral support for the revolutionary new approaches to cancer research and treatment.

Less Inflammation, Longer Life


The passage below is from a WSJ summary of an article that appeared in the December 2007 issue of Discover:

(p. B12) Scientists are increasingly hopeful that controlling inflammation will allow them to turn back the clock on aging, writes Kathleen McGowan in Discover magazine.
Inflammation is already a well-established predictor of many chronic illnesses, such as diabetes, atherosclerosis and Alzheimer’s disease.  . . .
. . .
Many prominent gerontologists reason that if these chronic diseases are the product of an overactive immune system, then they can be countered with the right anti-inflammatory drug.    . . .
“The research is really to prevent the chronic debilitating diseases of aging,” says Nir Barzilai, a molecular geneticist and director of the Institute for Aging Research at the Albert Einstein College of Medicine in New York. “But if I develop a drug, it will have a side effect, which is that you will live longer.”

Columbus Absolved of Bringing Lice-Borne Disease to Indians

“Braided hair is intact on a Peruvian mummy like those used in a study. Scientists say lice in the Americas predated Columbus.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A10) When two pre-Columbian individuals died 1,000 years ago, arid conditions in the region of what is now Peru naturally mummified their bodies, as well as the lice in their long, braided hair.

That was all scientists needed, they reported Wednesday, to extract well-preserved louse DNA and establish that lice had accompanied their human hosts in the original peopling of the Americas, probably as early as 15,000 years ago. The DNA matched that of the most common type of louse known to exist worldwide now and also before Europeans colonized the New World.

The findings absolve Columbus of responsibility for at least one wrong unintentionally wrought on the people he found in the Americas and called Indians. The Europeans who followed Columbus to America may have introduced diseases, namely smallpox and measles, but not the most common of lice, as had been suspected.

“The No. 1 Need that Poor People Have is a Way to Make More Cash”

 

  Moving water is easier with the 20-gallon rolling drum.  Source of photo:  online version of the NYT article quoted and cited below.

 

(p. D3)  . . . , the Cooper-Hewitt National Design Museum, . . . , is honoring inventors dedicated to “the other 90 percent,” particularly the billions of people living on less than $2 a day.

Their creations, on display in the museum garden until Sept. 23, have a sort of forehead-thumping “Why didn’t someone think of that before?” quality.

. . .

Interestingly, most of the designers who spoke at the opening of the exhibition spurned the idea of charity.

“The No. 1 need that poor people have is a way to make more cash,” said Martin Fisher, an engineer who founded KickStart, an organization that says it has helped 230,000 people escape poverty.  It sells human-powered pumps costing $35 to $95.

Pumping water can help a farmer grow grain in the dry season, when it fetches triple the normal price.  Dr. Fisher described customers who had skipped meals for weeks to buy a pump and then earned $1,000 the next year selling vegetables.

“Sometimes It Pays to Read the Old Literature”

(p. A1) Researchers in New York believe they have solved one of the great mysteries of the flu: Why does the infection spread primarily in the winter months?

The answer, they say, has to do with the virus itself. It is more stable and stays in the air longer when air is cold and dry, the exact conditions for much of the flu season.

. . .

(p. A22) To his surprise, Dr. Palese stumbled upon a solution that appeared to be a good second best.

Reading a paper published in 1919 in the Journal of the American Medical Association on the flu epidemic at Camp Cody in New Mexico, he came upon a key passage: “It is interesting to note that very soon after the epidemic of influenza reached this camp, our laboratory guinea pigs began to die.” At first, the study’s authors wrote, they thought the animals had died from food poisoning. But, they continued, “a necropsy on a dead pig revealed unmistakable signs of pneumonia.”

Dr. Palese bought some guinea pigs and exposed them to the flu virus. Just as the paper suggested, they got the flu and spread it among themselves. So Dr. Palese and his colleagues began their experiments.

. . .

As for Dr. Palese, he was glad he spotted the journal article that mentioned guinea pigs.

“Sometimes it pays to read the old literature,” he said.

Government Pushing Fluorescent Bulbs with Hazardous Mercury

 

BulbSkull.jpg    Source of image:  online version of the WSJ article quoted and cited below.

 

(p. D1)  As part of the government’s focus on energy and the environment, Americans are urged to buy compact fluorescent light bulbs, which use only about 25% of the energy and last up to 10 times as long as traditional incandescent bulbs. Nearly 300 million such bulbs were sold in U.S. in 2007, compared with 100 million two years earlier, according to the Department of Energy.

. . .

Yet unlike traditional incandescent bulbs, these bulbs contain mercury, a metal hazardous to human health and the environment. Consumers are urged not to toss them in the trash. In some states, such as California, it’s illegal to throw them away; they must be recycled. Still, many cities and towns don’t have recycling programs for the bulbs, and consumers aren’t sure what to do with them.

Google and Microsoft Seek to Shift Health Care Power to Consumers

 

InternetHealthGraph.jpg    Source of graph:  online version of the NYT article cited below. 

 

(p. C1)  In politics, every serious candidate for the White House has a health care plan. So too in business, where the two leading candidates for Web supremacy, Google and Microsoft, are working up their plans to improve the nation’s health care.

. . .

(p. C8)  If the efforts of the two big companies gain momentum over time, that promises to accelerate a shift in power to consumers in health care, just as Internet technology has done in other industries.

Today, about 20 percent of the nation’s patient population have computerized records — rather than paper ones — and the Bush administration has pushed the health care industry to speed up the switch to electronic formats. But these records still tend to be controlled by doctors, hospitals or insurers. A patient moves to another state, for example, but the record usually stays.

The Google and Microsoft initiatives would give much more control to individuals, a trend many health experts see as inevitable. “Patients will ultimately be the stewards of their own information,” said John D. Halamka, a doctor and the chief information officer of the Harvard Medical School.

Already the Web is allowing people to take a more activist approach to health. According to the Harris survey, 58 percent of people who look online for health information discussed what they found with their doctors in the last year.

It is common these days, Dr. Halamka said, for a patient to come in carrying a pile of Web page printouts. “The doctor is becoming a knowledge navigator,” he said. “In the future, health care will be a much more collaborative process between patients and doctors.”

Microsoft and Google are hoping this will lead people to seek more control over their own health records, using tools the companies will provide.

Health Care Costs Are High and Rising

 

   Source of graph:  online version of the Omaha World-Herald article quoted and cited below.

 

The article quoted below summarizes a seminar by Dr. John Abramson.  He was right to highlight the high costs of health care in the U.S., though he didn’t show any special insight in suggesting solutions.

 

(p. 1D)  Costs are out of control, he said, and yet the United States, out of 22 developed nations, pays the most per person for health care and ranks last in having citizens lead long, healthy lives.
