First, Do Net Harm?

• 14

By Eric Topol, MD

Recently, the US Preventative Services Task Force reiterated its recommendation that women not undergo routine screening for ovarian cancer. This was remarkable, not simply because it was a recommendation against screening, but because the task force was making the recommendation again, and this time even stronger.

The motivation for the recommendation was simple: a review of years’ worth of data indicates that most women are more likely to suffer harm because of false alarms than they are to benefit from early detection. These screenings are a hallmark of population medicine—an archetypal form of medicine that does not attempt to distinguish one individual from another. Moving beyond the ritualistic screening procedures could help reduce the toll of at least $765 billion of wasted health care costs per year.

We already know the common changes in the DNA sequence that identify people who have higher risk of developing ovarian, breast or prostate cancer and most other types of cancer. Consumers can now readily obtain this information via personal genomic companies like 23andMe or Pathway Genomics. But we need to do much more DNA sequencing to find the less common yet even more important variations—those which carry the highest risk of a particular cancer. Such research would be easy to accomplish if it were given top priority and it would likely lead to precision screening. Only a small fraction of individuals would need to have any medical screening. What’s more, it will protect hundreds of thousands of Americans from being unnecessarily harmed each year.

Is Prostate Cancer Screening Truly Harmful?

• 7

By Peter Ubel

Dr. Timothy Wilt, a member of the United States Preventive Services Task Force, stood in front of the American Urological Association audience and explained why the task force could not recommend that men undergo routine PSA screening. At most, he explained, the test had been shown to benefit one out of 1000 men. Meanwhile, the test would cause hundreds of men to experience anxiety, and scores of them to experience impotence and incontinence from unnecessary treatments.

Twenty minutes later, I stood behind the same podium and asked the audience members to raise their hands if they disagreed with the task force’s conclusion. Ninety percent expressed their skepticism. What happened in the time between Wilt’s presentation and mine reveals a great deal about why experts cannot agree whether screening tests, like the PSA in middle-age men or mammograms in 40-year-old women, bring more benefit than harm, and about what psychological forces impede our ability, as a society, to figure out what basic bundle of healthcare services all insurance companies ought to pay for.

Wilt’s presentation was a model of scientific clarity. He explained that only two randomized clinical trials were conducted with enough scientific rigor to provide useful estimates of whether the PSA test saves lives. One trial showed no benefit and the other revealed the one in 1000 number which the task force took as the best case scenario. Wilt was followed on stage by Ruth Etzioni, a biostatistician at the Fred Hutchinson Cancer Research Center in Seattle.  Etzioni presented a statistical model suggesting that the PSA test benefited many more than one in 1000 men.

How Much Weight Should Anecdotes Really Have In Health Policy?

• 0

By D. Brad Wright


There’s something compelling about the personal narrative that vast mountains of quantitative data cannot rival. Anecdotes are, quite simply, powerful. They tap into our shared humanity, making something seem somehow more real by putting a face on it. This is why, if you follow politics for very long, you will find numerous cases of policymakers championing issues that have touched their own lives in some way. For example, Senator X doesn’t care about issue Y, until they discover that their son or daughter is affected by it. Then, almost overnight, they seem to care more about issue Y than almost anything else. Such a shift is completely understandable, but often out of proportion to the true scale of the issue in society.

In health policy, the personal narrative can also be very powerful. In fact, the journal Health Affairs routinely runs a “Narrative Matters” section that puts a face on the health care issues of the day. It is absolutely critical that health policymakers, health services researchers, and others, not lose sight of the fact that their work and the subsequent decisions it informs, are based on real people. However, it is equally critical for objectivity to be maintained, and narrative can threaten our work in this regard.

USPSTF – It’s About Time

By Merrill Goozner

The numbers are stark. According to the United States Preventive Services Task Force, for every man whose death from prostate cancer is prevented through PSA screening, 40 become impotent or suffer incontinence problems, two have heart attacks and one a blood clot. Then there’s the psychological harm of a “false positive” test result, which is 80 percent of all “positive” tests. They lead to unnecessary worry, follow-up biopsies, physical discomfort and even harm. Final grade: D.

Three men close to me have been diagnosed with prostate cancer late in life. Each was around 70. My dad, already in throes of advancing Alzheimer’s disease, did what the doctor ordered (actually, I suspect my mom told my dad to do what the doctor ordered). He had surgery. And for the last six years of his life, which until his final three months was at home, she cleaned up after him because of his incontinence. My neighbor made the same choice. He quietly admitted to me one day that he suffers from similar symptoms, but he is grateful because he believes his life was saved by the operation. And my friend Arnie? I’ve written about him in this space before. He was diagnosed at 70, and being a psychiatrist with a strong sense of his own sexual being, understood the potential tradeoffs. He decided to forgo treatment. He died a few years ago at 90. I never learned the cause.

So what does it mean that PSA testing gets a D rating?

Top 10 Reasons Why Warren Buffett’s Decision to Treat Prostate Cancer Bugs Me

• 7

By Laura Newman

On April 17th, 81-year-old Warren Buffett told investors that he had very early prostate cancer. The Washington Post headline read: “Warren Buffett Has Prostate Cancer that is Not Remotely Life Threatening.’” Within hours, news accounts said that the story unfolded after discovering a high PSA in a routine appointment. Next, he had a prostate biopsy. A few hours later, news accounts said that Buffett decided to get radiation therapy for prostate cancer. What’s wrong with this picture?

10. He’s an icon who other men will follow, and there is limited (or no) evidence of benefit of aggressive treatment in men as old as Buffett. At 81, his life expectancy is 7.41 years, shy of the 10-year life expectancy mark doctors look for when they recommend aggressive treatment for prostate cancer.

9. Although Buffett can afford whatever care he so desires, it would cost a fortune if tons of men in his age group went for active treatment and there would be little yield and plenty of side effects.

Accountable Care Organizations and Antitrust

• 7

By TIM GREANEY

There’s a new PSA test in health care.  Hopefully it will prove more reliable than that other one.

In conjunction with the unveiling of the long-awaited ACO regulation by HHS, the FTC and Department of Justice issued a Joint Policy Statement setting forth their standards for conducting an expedited (90-day) antitrust review of applicants for ACO certification.  The agencies explained that they will evaluate applicants’ market power based on the ACO’s share of services in each participant’s Primary Service Area (PSA) defined as the “lowest number of contiguous postal zip codes” from which the hospital or physician draws at least 75 percent of its patients for its services.   The Statement summarized the antitrust implications of ACOs formed by hospitals or physician groups with large market shares in their markets:

ACOs with high PSA shares may pose a higher risk of being anticompetitive and also may reduce quality, innovation, and choice for both Medicare and commercial patients. High PSA shares may reduce the ability of competing ACOs to form, and could allow an ACO to raise prices charged to commercial health plans above competitive levels.

The antitrust enforcers were properly concerned with the risk that ACOs could become a vehicle for increasing or entrenching provider market power.  Studies by academics, health policy experts and state governments have documented the impact of provider concentration on insurance premiums. Moreover, a post-reform merger wave may have increased the number of hospital and specialty physician markets and many areas are already served by dominant local providers.  Inasmuch as the success of the ACO concept depends on its ability to spur delivery system change, the predictable intransigence of monopolistic providers presents an important issue. In this regard, it is heartening that the extended (and apparently controversial) regulation drafting process produced a result that promises to constrain the growth and exercise of market power.Continue reading…
