The Voltaire of health economics

MAYNARD MATTERS
Critical Thinking on Health Policy

For any health economist, Alan Maynard is a reference. We've been reading his contributions for decades and now we can read a book (free to download) that has two parts. The first shows different views of his role on health economics and policy,  while the second is a selected collection of articles and book chapters.
I would like today to highlight what Rudolf Klein says about what he calls "The Voltaire of Health Economics":
I am sceptical about some of the claims to special policy wisdom of economists operating in
the health field. Too many, I find, seem to have a naive faith in QALYs, reflecting methodological innocence and an unreflective utilitarianism. Too many, in my view, appear to think that evidence should guide policy action in situations where only policy action can produce the evidence. Too
often I find myself bemused by statistical wizardry, wondering whether the inevitable simplifications required by modelling don’t exclude crucial dimensions of a complex world
The reasons for my admiration stem from Alan’s specialcombination of energy, moral drive and irreverence.  
Alan is a moralist. For him a failure to act on – or, if need be, generate – the evidence for a policy intervention is an ethical failure. So identifying what interventions give the “biggest bang for the buck” is the moral obligation of all policy makers. He sees a reform of the NHS, or indeed of any health care system, “as an experiment on fellow citizens”, which has to be justified and undertaken responsibly, and not on some ideological whim.
I agree absolutely on Rudolf Klein views.
In chapter 13 you'll find a book chapter "Health Economics: Has it fulfilled its
potential?" that is abstracted by the editor's with this words:
Whilst Maynard argued strongly for the importance of generating and using cost-effectiveness data in decision making, he was concerned that this had encouraged an industry of health economists rolling out economic evaluations. The victory of the health economics perspective in how to ration health care resources led to health economics becoming the slave of the cost-effectiveness industry, feeding regulators such as NICE and also the pharmaceutical and device manufacturers seeking to get their products approved and funded. This distorted the role of health economics and only used a small part of the full repertoire of perspectives and techniques that economics could apply to health and healthcare problems. He argued here that health economists need to keep a strong link with economics as a discipline and apply themselves to a wider range of problems such as supply and demand, the workforce, incentives and behaviour change, pricing and equity.
 As the front page says:
Brilliant, irreverent and almost always right – essays by a sceptical health economist who changed the way we think about policy
A must read.

The two friends story

THE TWO FRIENDS WHO CHANGED HOW WE THINK ABOUT HOW WE THINK

Sunstein and Thaler provide an excellent review of a unique book by MichaelLewis in New Yorker. This is my suggestion for reading today.

Healthy lifespans are improving, do we know why?

Understanding the Improvement in Disability Free Life Expectancy In the U.S. Elderly Population

If you want to know the reason behind the improvement of healthy life expectancy in US, then you have to read this chapter.  Three fundamental conclusions:
First, we show that healthy life increased measurably in the US between 1992 and 2008. Years of healthy life expectancy at age 65 increased by 1.8 years over that time period, while disabled life expectancy fell by 0.5 years. Second, we identify the medical conditions that contribute the most to changes in healthy life expectancy. The largest improvements in healthy life expectancy come from reduced incidence and improved functioning for those with cardiovascular disease and vision problems. Together, these conditions account for 63 percent of the improvement in disability-free life expectancy. Third and more speculatively, we explore the role of medical treatments in the improvements for these two conditions. We estimate that improved medical care is likely responsible for a significant part of the cardiovascular and vision-related extension of healthy life.
And this is what I said two years ago in this post with Catalonia data:
Fortunately, new data about recent trends has been published and we can confirm that has increased over a period of 7 years, between 2005 and 2012 from 63 to 65.7 years for men and from 60.6 years  to 66.1 for women . In women the proportion of years lived in good health has gone up by 5 percentage points, from 72 to 77 % in men and has increased only one point from 81 to 82 %. In any case, in marginal and in absolute terms there is a substantial improvement . Nobody would have been able to foresee changes of this magnitude.
Unfortunately we don't know why.

Simplistic arguments on healthcare cost growth

Technology Growth and Expenditure Growth in Health Care

After all these years of great recession, there is an argument that should be reviewed. There was a consensus that technology and ageing were forces that would increase costs. Today, we know that costs have stagnated and we are spending less resources over GDP than 7 years ago. Therefore, something has happened that requires an assessment. Maybe a delay on the introduction of innovation, maybe an increase in productivity, maybe a reduction in its costs/prices, we don't know it. Therefore health costs are not predestined to grow forever.
This is exactly what this article said about it:
Attributing cost growth and improvements in outcomes to “technology growth” is too simplistic and tells us little about where the cost growth is occurring, whether such growth should be tamed, and if so, how it should be done
 The key point is that U.S. growth in health care costs is neither inevitable nor necessarily beneficial for overall productivity gains. Instead, cost growth is the  aggregated outcome of a large number of fragmented decisions regarding the use and  spread of both old and new health technologies.
There is wide heterogeneity in the productivity of medical treatments, ranging from very high (aspirin for heart attacks and surfactants for premature births) to low (stents for stable angina), or simply zero (arthroscopy for osteoarthritis of the knee).

Why organizations are such a mess?

Many years ago I attended to a PhD course on Organizational Economics by Robbert Gibbons, from MIT. I still remember the title of one of his papers "Why organizations are such a mess". I found it really suggestive, because in a world of transaction costs the choice between organizations and markets is a difficult one, and Gibbons was trying to disentangle it. Later he coordinated the Handbook of Organizational Economics and contributed decisively to the development of the discipline. Last September he came back again at Universitat Pompeu Fabra and gave the annual lecture. It is an introduction to the key issues of organizational economics, highly recommended (starts at minute 12):

The farce of confidential drug prices

We are approaching the end of cost-effectiveness as we have known. If you can't use the price of the drug because it is confidential, then there is no possibility of cost-effectiveness analysis. As far as Pfizer has sued a public agency because its officials have leaked the prices, then everybody that uses such information is at risk of being sued. I had already said that some time ago, when in our country we moved to confidential prices. This trend is ridiculous, getting better discounts comes at the price of opacity. And opacity is an extraordinary arm to prevent competition and constrain prioritisation. Qui prodes? It's up to you to get the answer, for me it's clear. If money comes from taxes, the citizens have to know the final price paid. The time to finish such farce has come.

PS. On why external reference pricing is meaningless (p.36):
The practice of lowering list prices through discounts, rebates and similar financial arrangements15 between public payers and the MAH is wide-spread. 22 countries reported that discounts, rebates or similar financial arrangements (e.g. managed-entry agreements such as risk sharing schemes) – either statutory (i.e. based on a law) or confidential (based on agreements) – are in place. As will be discussed later in more detail (cf. Chapter 4.1.2), the widespread use of the discounts and similar provides financial benefits to the country using it, but the other countries referencing to that country do not benefit from the lower prices since they refer to undiscounted higher prices.

In Memoriam of Thomas Schelling

Thomas Schelling: Game Theory, Cold War, Coordination, Leadership, Tipping, Focal point...

Eleven years ago, Thomas Schelling was awarded with the Nobel Prize, 4 days ago he died. It is not often that one man has such a profound impact on the world and the field of public policy. In this blog I have devoted some posts to him: Statistical life vs. identifiable life, Els pirates dels medicaments s'escapoleixen, Validesa i utilitat de les proves genòmiques.  Basically, all of them were related to his main contribution: The Strategy of conflict, a must read book for all people interested in negotiation. Today, the best thing you can do is to read Josep M. Colomer and his post on Schelling, it fits perfectly with his contribution and message, excellent post.
