This ABC piece by John Paulos points out how the public is misled about the magnitude and significance of medical results.
That being said, imagine that a headline announces that screening for cancer X reduces deaths from it by 25 percent. Imagine as well that another headline announces that screening cuts deaths from cancer X by about 1 in 1,000, reducing the rate from 4 in 1,000 to 3 in 1,000.
25% is much more impressive than a drop of 4 in 1,000 to 3 in 1,000
See this in a British newspaper touting the results of the Jupiter study. This article reads like a PR release from AstraZeneca the makers of Crestor.
The Jupiter study showed heart attacks were cut by 54 per cent, strokes by 48 per cent and the need for angioplasty or bypass was cut by 46 per cent compared with a placebo. Levels of ‘bad’ cholesterol were halved.
Experts say the results would not necessarily be found with other statins because some work differently.
But in another interpretations of the Jupiter study published in the New England Journal:
The relative risk reductions achieved with the use of statin therapy in JUPITER were clearly significant. However, absolute differences in risk are more clinically important than relative reductions in risk in deciding whether to recommend drug therapy, since the absolute benefits of treatment must be large enough to justify the associated risks and costs. The proportion of participants with hard cardiac events in JUPITER was reduced from 1.8% (157 of 8901 subjects) in the placebo group to 0.9% (83 of the 8901 subjects) in the rosuvastatin group; thus, 120 participants were treated for 1.9 years to prevent one event. (Medicynical emphasis)
Not nearly as impressive as the 54% reported in the news article.
This type “interpretation” of results is common. PhARMA companies maximize the “benefit” by using relative rather than absolute values. In addition to overemphasizing the medical benefit their interpretation also doesn’t factor in toxicity and cost. Somewhere, somehow in our “reformed” health care system we need to look at this.

Nice review of five of inexplicably popular alternative modalities with references here.
As you’d expect reiki, reflexology, zone therapy, homeopathy, magnetic therapy, and kava don’t work. Also inexplicably some insurers cover such nonsense.

In 1989, a study from Stanford posited that support groups helped patients with cancer live longer. The study was flawed by small numbers (86 patients), the fact that the many patients who died early on were weighted less in the results than the few that had long survivals.
Immediately counseling groups developed cancer support programs, costing a fortune. Everyone wanted to feel “better” about their disease and reap the benefit of a longer life. It was amazing that this bad study’s impact was so great.
For the patient caught up in the maelstrom of bad science, in a subtle way, it became their fault that the disease progressed–because they didn’t have a positive enough outlook.
This all was proven to be nonsense as one would expect. In 2007 the same author, David Spiegel, in a
small study (125) patients tried to “replicate” the previous flawed study. He found this time, as others have documented, no effect on survival from participation in these support groups.
In the interim Spiegel became a guru for support groups to improve survival of cancer patients and literally made a career speaking and appearing on TV flogging his bogus hypothesis. He’s still talking as noted in this
NY Times article which takes an appropriately skeptical view of benefits of happiness.
Medicynical note: Having experienced cancer in a loved one I’m aware of the difference between being delusional and realistic; Between trying everything and trying everything that makes sense. One of the drivers of cost of health care in our culture is the notion that there must be “something” that will work and that we are all entitled to try everything. I’m not sure how we approach this.

The republican strategy to oppose and campaign against health reform is the best news the country could have as it will be disastrous for republican election hopes.
Consider the millions who benefit from the bill; the cost savings accruing from health reform; the disappearance of medical expense caused bankruptcy; the fact that we are the last industrialized nation to have some form of national health scheme.
If the bill had passed during the Clinton administration is likely the GM and Chrysler bankruptcies would have been avoided.
This in support of health reform from the December 2, NEJM article by Jonathan Gruber, Ph.D.
One common refrain of opponents of reform is that it represents a government takeover of health care. But reformers made the key decision at the start of this process to eschew a government-driven redesign of our health care system in favor of building on the private insurance system that works for most Americans. The primary role of the government in this reform is as a financier of the tax credits that individuals will use to purchase health insurance from private companies through state-organized exchanges. In Massachusetts, which passed a similar reform in 2006, private health insurance has expanded dramatically. The public insurance alternative that is included in the Senate bill simply adds another competitor — on a level playing field — to the insurance market, and the Congressional Budget Office (CBO) projects that it will enroll only a tiny minority of Americans.
And
A second criticism is that the bills are budget busters. This is simply incorrect. Both bills are completely paid for — indeed, both would reduce the deficit by more than $100 billion over the coming decade. And the CBO estimates that both would reduce the deficit even more in the long run, particularly the Senate bill with its strong cost-containment measures.
Regarding Medicare
In any case, there is substantial evidence that reducing these overpayments will not harm the health of Medicare patients — just the pocketbooks of those who profit from them. This reform would simply use market bidding to set the reimbursement rate for Medicare Advantage plans, rather than setting administrative prices, which have traditionally been much too high; and it would reduce payments to hospitals by a small percentage, while tying them to outcome measures.
and so on.
Medicynical Note: Perfect, NO. A good start, yes!

It’s too bad that health care reform has been gutted by special interests. In addition to the Nelson and Landrieu obscenities drug companies have taken advantage.
This is not new behavior for these guys. The patented drug pharmaceutical industry has always been in the forefront of dubious practices aimed at making money, not improving care.
I can recall as a senior medical student being taking for a weekend to New York, all paid for by a drug company. On graduation these so called “ethical” pharmaceutical companies gifted students with doctor bags, books, and instruments all for the purpose of maintaining brand consciousness.
It’s therefore a little disconcerting to watch these same interests work to undermine parts of health “reform” to maintain their grip on products and pricing. Included in the bill are:
extensive protections against generic versions of pricey biotech medicines, an incentive for Medicare recipients to use more brand-name drugs,
more, not less, patent protection for drugs costing more than most U.S. citizens make in a year.
Like the House bill, the Senate bill gives the Food and Drug Administration power to allow biogenerics onto the U.S. market. Such protein-based medicines treat cancer and other conditions but can cost tens of thousands of dollars a year per patient.
Generic makers welcomed the pathway to approval, but the bills provide for a 12-year period of exclusivity for brand-name drugs before a biogeneric can be approved. The Obama administration had sought just five to seven years of protection. (Medicynical emphasis)
Drug companies claim they need the protection to recoup research costs. But if they have to charge $10,000/month and more for new biotech drugs then they are either exceptionally inefficient (FYI they spend tens of billions on marketing which they have to also recoup), or the drug is simply too expensive for our system to afford. Sadly to this point most of these new agents offer only slight, if any (that is no proven survival benefit) over other therapies. Paying a premium for such agents is a little nuts.
The Senate seems to have outdone itself in protecting drug companies, how about something for U.S. taxpayers who will be paying the bills for these new but, so far, marginally effective drugs.

Alain Enthoven has a review of the problems of cost containment.
Ultimately the reason we need health reform is because our costs exceed our ability to pay. The current bill doesn’t approach this issue. It is more a bill designed to protect the income and profits of the current players than to reform it.
Enthoven’s solution:
What should be done? I explained it in my “Consumer Choice Health Plan” articles in the 1978New England Journal of Medicine. The idea is also in a recent report by the Committee for Economic Development (CED). The general idea is for government to pay everyone’s way into the purchase of an efficient or low-cost health plan, meeting standards in their state or region but no more; if people want something that costs more, they must pay the difference with their own net after-tax dollars. Additionally, the creation of exchanges that broker multiple choices of health plans would drive the delivery system to produce better value through consumer choice and competition.

Our opposition party health care plan, if you can find it, seems to favor free market approaches and free emergency room access.
Such a vague “plan” leaves moot the issue of the influence of Madison Avenue on patient decisions. Drug companies, for example, spend tens of billions of dollars on advertisements to influence patients. They must have a significant effect, how else to explain their continuing and increasing prevalence.
It’s therefore concerning, particularly if you think markets are the answer, that physicians and institutions use ads to overstate their capabilities and results.
Medicynical Note: We live in a manipulated world. There is really no free and open market. In health care. Most people cannot hope to be fully informed and understand their medical problems, treatments and options. The internet has sources of widely varying quality. To understand this, simply Google (or Bing) a diagnosis, and try to sort through and find the evidence based information.
Ineffective and modestly effective approaches are being actively marketed for use at horrific cost to the individual and the system. Hopefully this will be reformed.

The alternative medicine community operates in a cloud (claims without hard evidence) based in part on the notion that whatever they do has to “improve the immune system.” There is little basis for this claim in improved outcomes, other than placebo effect.
A recent study in the Journal of AMA (JAMA. 2009;302:2119-2126) reports on a two placebo controlled studies from Norway in which patients received folic acid and vitamin B12.
The results indicate an excess of 3.5 new cases/1000/year and one excess case of lung cancer per 1,000 per year
Patients were followed for over three years. More patients receiving the vitamins were diagnosed with cancer (10% vs 8.4% P=.02) and more receiving the vitamins died (4% vs 2.9% P=.01). Another way of stating this, if we wanted to maximize the claim, would be that there was an almost 16% increase in cancer diagnoses and a 28% increase in death. Medicynical note: whenever you hear a percentage increase or decrease in something you can assume it overemphasizes the result.
About all that one can say about this study is that, regarding cancer prevention, B12 and folate offer no benefit and may even increase the risk.
Medicynical Note: One explanation of the finding is that in addition to whatever “positive” effects there are, B12 and folate also enhance the growth of cancer cells in some patients. One needs to be careful about therapeutic weapons that “enhance” something because they have double edges and enhance the wrong thing.

It’s fascinating to watch our flawed legislative system “work.” Buy offs, illegitimate martinets demanding their 15 minutes, deals with money hungry corporate entities, bribery at every level, compromises until it’s hard to recognize what’s really been accomplished and complexity that violates the KISS principle. It’s certainly not pretty, efficient or effective.
Despite all that the resulting bill improves the current dysfunctional non-system and should be passed. This conclusion is more a comment on the current pathetic state of health care in America than an unqualified endorsement.
In a “two party” democracy one would have thought the opposition would have something to offer. But in this case the best they could do was maintain that free emergency room care was the answer to our health care problems. Incredible.
The bill allows insurers to rate on age but appears to stop the practice of varying rates according to illness.
‘‘(a) IN GENERAL.—With respect to the premium rate charged by a health insurance issuer for health insurance coverage offered in the individual or group market—
‘‘(1) such rate shall vary only by— ‘‘(A) family structure; ‘‘(B) community rating area; ‘‘(C) the actuarial value of the benefit; ‘‘(D) age, except that such rate shall not
vary by more than 2 to 1; and
‘‘(2) such rate shall not vary by health status- related factors, gender, class of business, claims ex- perience, or any other factor not described in paragraph (1).
The publicity on the bill claims no one can be denied coverage and that rates will not be increased (presumably after issuance) for a pre existing illness. It does sanction a 3:1 increase based on increasing age, hardly a people friendly policy. Considering that the average cost of insurance for a family is in the range of $10,000, such variation in charges are prohibitive. If this is so it’s hardly a benevolent system or one in which the health and well-being of those covered is the primary objective.
See this in LA Times
Companies in the exchanges would have to offer policies to all customers, regardless of their health status. Insurers could not charge older people more than three times what they charge their youngest customers, an unprecedented national restriction on what is known as age-rating.
It’s also unclear what the bill will do to decrease costs to a more reasonable level; to rein in corporate profits; or whether it will provide objective evaluations of the effectiveness of outrageously expensive therapies and improve efficiency.
Until we are more concerned with patients than corporate profits our health care will be costly and, for the amount spent, mediocre.
Medicynical Note: I’m in awe of a health care system that can charge $20 for a flu vaccine and then add $38 to the bill as a fee for the injection–as I was recently billed. We need to put the health care reform ball in play and make changes in its trajectory as we go.
