When asking your physician is not enough

23andMe and the FDA

Some weeks ago I explained the FDA "closure" of DTC genetic testing business. NEJM analyses with detail the rationale behind such policy:
The goal of the FDA and 23andMe (as well as all clinical geneticists, testing laboratories, and the entire genetics industry) should be to ensure that genomic information is both accurate and clinically useful. Clinicians will be central to helping consumer–patients use genomic information to make health decisions. Any regulatory regime must recognize this reality by doing more than simply adding the tagline on most consumer ads for prescription drugs: “Ask your physician.” That is insufficient guidance unless your physician has ready access to a clinical geneticist or genetic counselor.
European regulation is 15 years old and the new directive is still being discussed. It will not be applied for at least 3 years. Meanwhile, do you know who is protecting us from inaccurate and clinically useless information?

Let's get fit, not fat

Aportaciones de la economía del comportamiento en política sanitaria: Algunas notas en torno al ejemplo de la obesidad
 The influence of obesity and overweight on medical costs: a panel data perspective

In the EJHE you'll find  a clear message:
The results indicate that obesity is associated with substantial healthcare cost increases and there are large differences in costs by degree of obesity. Specifically, severe obesity raises total direct medical costs by an average of 160 € per patient and year. With total medical costs averaging 600 € for normal-weight individuals, this means that severe obesity is associated with an increase in costs of 26 %. The effect of moderate obesity is more modest: it raises medical costs by 97 € or 16 %. Overweight has an even smaller impact, raising costs by 51 € or 8.5 %.
Therefore, if obesity has an economic and health impact, what next?
The EEA article by A. Garcia-Altés reflects current knowledge on behavioral economics and obesity. However there is a long way to go. As I said in a former post we do need a battery of measures to fight obesity: regulatory, social and individual measures.

Our irrational behaviour

The Behavioral Economics of Health and Health Care
Irrationality in Health Care: What Behavioral Economics Reveals About What We Do and Why

Thomas Rice provides an overview of behavioral economics in health in a recent article in Annual review of public health. More or less the same things we already know with some concrete messages. A good starting point for those that want to take first steps in this discipline. The summary:
People often make decisions in health care that are not in their best interest, ranging from failing to enroll in health insurance to which they are entitled, to engaging in extremely harmful behaviors. Traditional economic theory provides a limited tool kit for improving behavior because it assumes that people make decisions in a rational way, have the mental capacity to deal with huge amounts of information and choice, and have tastes endemic to them and not open to manipulation. Melding economics with psychology, behavioral economics acknowledges that people often do not act rationally in the economic sense. It therefore offers a potentially richer set of tools than provided by traditional economic theory to understand and influence behaviors
Right now behavioral economics is still a promise, let's wait until we can really apply it widely.
Thomas Rice says in this respect:
 With the exception of Kahneman & Tversky’s prospect theory, which was developed more than 30 years ago, there has been little in the way of bringing the various tools and policies of behavioral economics under one umbrella. As a result, most of the applications seem to be ad hoc. More development of an overarching theory could aid those interested in designing new interventions when it is clear that traditional economics remedies are insufficient
Regarding the book on Irrationality in Health Care, I haven't had the opportunity to have a look at it. I leave here the reference and 23 anomalies . Maybe in the book there is the answer to solve them.

Hostis populi

A plot written by Ibsen in 1882 could reflect current conflicts nowadays. Whats first: Your money or your health?. I went to the theatre last week. Great "mise en escène".
The summary:
Doctor Thomas Stockmann is a popular citizen of a small coastal town in Norway. The town has invested a large amount of public and private money towards the development of baths, a project led by Stockmann and his brother, Peter, the Mayor. The town is expecting a surge in tourism and prosperity from the new baths, which are said to be of great medicinal value, and as such, a source of great local pride. Just as the baths are proving successful, Stockmann discovers that waste products from the town's tannery are contaminating the waters, causing serious illness amongst the tourists. He expects this important discovery to be his greatest achievement, and promptly sends a detailed report to the Mayor, which includes a proposed solution which would come at a considerable cost to the town.
To his surprise, Stockmann finds it difficult to get through to the authorities. They seem unable to appreciate the seriousness of the issue and unwilling to publicly acknowledge and address the problem because it could mean financial ruin for the town. As the conflict develops, the Mayor warns his brother that he should "acquiesce in subordinating himself to the community." Stockmann refuses to accept this, and holds a town meeting at Captain Horster's house in order to persuade people that the baths must be closed.
The townspeople — eagerly anticipating the prosperity that the baths will bring — refuse to accept Stockmann's claims, and his friends and allies, who had explicitly given support for his campaign, turn against him en masse. He is taunted and denounced as a lunatic, an "Enemy of the People." In a scathing rebuttal of both the Victorian notion of community and the principles of democracy, Stockmann proclaims that, in matters of right and wrong, the individual is superior to the multitude, which is easily led by self-advancing demagogues. Stockmann sums up Ibsen's denunciation of the masses with the memorable quote "...the strongest man in the world is the man who stands most alone." He also says: "A minority may be right; a majority is always wrong.
 I deeply disagree with this final generalization. The details are important.

Our health and its determinants

The quality cure into action

The next David Cutler book: "The Quality Cure. How Focusing on Health Care Quality Can Save Your Life and Lower Spending Too" will appear in April. Meanwhile we can read some pages from Google Books. He sets "quality" at the top of the agenda and he explains that Obamacare is trying to solve access. Focusing on quality means effort on greater value, avoiding waste, and therefore cost containment. At the begining it may seem an already heard message, however I agree with him that the quality chasm must be addressed, as well in our country. The book is a must read beyond US borders for any person involved in health care as it is his former book "Your money or your life" . The first statements from the preface:
For decades, health care was like the weather-everybody talked about it, but nobody did anything about it. Talk was easy, politicians and analysts of all stripe agreed that we wanted a health care system focused on preventing disease and treating it appropriately when necessary. In the past half decade, talk has turned into action.
Let's apply his final words,  it's time to turn talk into action.

The hole for genetic testing market entry

Technology Assessment on Genetic Testing or Molecular Pathology Testing of Cancers with Unknown Primary Site to Determine Origin
Update on Emerging Genetic Tests Currently Available for Clinical Use in Common Cancers

AHRQ has just published two reports of interest. The first is devoted  to assess the evidence on the analytical validity, clinical validity, and clinical utility of commercially available genetic tests for identifying the tissue of origin (TOO) of the cancer in patients with cancer of unknown primary (CUP) site. The second describes genetic tests that have applications in the common solid tumors (breast, lung, colorectal, pancreas, etc.) as well as tests that are used in hematologic cancers (leukemia, lymphoma) and are already available in clinical practice.While the first is an assessment, the second is informative.
There is still a third report to be released and meanwhile NRD explains its conclusions. Having selected 11 prognostic tests, only around half had evidence supporting their prognostic accuracy or clinical validity. Therefore the question is always the same: why these tests without evidence are on the market? Why have they been approved by the FDA?. There is a big regulatory hole to fill in.
