Doing what works

Rediscovering the Core of Public Health

An update on the focus of public health is welcome. The article in the annual review is a good starting point:

Public health needs to transition from a twentieth-century model grounded in a biomedical model and categorical funding of disease-specific interventions to emphasize changes in the greatest determinants of health: our social and physical environments. Although improvements to date from public health need to be sustained, new perspectives and capabilities are essential to address contemporary and projected disease and injury burdens effectively.

The suggestion to analyse life trajectories sounds interesting. 

Are you satisfied?

If we take into account the results of the health barometer, the answer is YES, and now more than ever!. It sounds weird since the current debate about budget cuts would predict a decline in satisfaction with health services. Ctizens valued health care with 6.89 in 2012. We have right now slightly higher values than 2009, before the downturn. These figures require an explanation. It seems that there is a divorce between how people assess health services and how such situation is broadcast by the press? What's up?.

PS. Somebody has to fix this news.

 Remember, Katie Melua at Jardins de Cap Roig, this is the summer concert!

Genome sequencing mess

Since the world is more complex than it used to be, it is our duty to prevent any further complication. However sometimes some individuals forget it. The anouncement of sequencing genome for 100.000 citizens in UK last December raised controversy and BMJ right now publishes a head to head on this issue.
This blog has remarked many times that if effectiveness of any benefit is undemonstrated, then value is uncertain and potential harm of its application exists.
The summary of the position against sequencing is the following one:

If we sequence individuals’ DNA and tell them that they are genetically predisposed to be slightly more at risk of common diseases, we may be doing them a great disservice, demotivating them from behaving sensibly. And the private sector will see a marketing opportunity for all sorts of clinically unnecessary and potentially damaging screening, with further negative and unintended consequences. Possessing the technical ability to do something new is not an immediate justification for going ahead with it, especially in such an ethically complex area. Good medical practice requires tests to answer a specific question with a reasonable expectation of results being interpretable and useful. Currently, whole genome sequencing in healthy individuals has nothing to offer clinically because most of the data generated are meaningless; the maxim first do no harm still holds.

However, a subtile strategy has emerged recently. The Wellcome Trust will  finance with 3.2 m € a pilot study in London to analyse 97 cancer predisposition genes starting in 2014. It's not by chance, it coincides with Angelina Jolie double mastectomy recent news, and the patent expiration in 2014 of BRCA genetic tests. Is this a philantropic affair? or market access strategy?. The answer is yours.

PS. Beware of nonprofit foundations working for profit. This is a succesful strategy for market access when regulatory constraints have been set up and transparency rules apply. In such cases free lunches exist suspiciously,  but in the long-run they always disappear, and the social cost is enormous.

Who pays and who benefits?

Lifetime Distributional Effects of Publicly Financed Health Care in Canada

A lifetime perspective on equity is needed. Short term analysis introduce confounding factors. Fortunately, today we have good news. The Canadian Institute of Health Information has released an interesting research using this approach, and these are the key results:

• Health care costs are higher for low-income groups, but differences are not as pronounced when estimated over the life course instead of in a single year (2011 in this analysis).
- Average lifetime health care costs are $237,500 per person in the lowest income group and $206,000 in the highest income group—a difference of 15%. The difference is much larger (60%) when considering the effect on a single year (2011).
• Tax payments to finance health care are higher among higher-income groups but, like health costs, the differences between income groups are less pronounced when taking a life course perspective.
- Over a lifetime, average annual tax payments to finance health care costs are approximately 8.5 times as high in the highest income group as in the lowest income group. A more pronounced difference of 10 times between groups is estimated when looking at 2011 only.
• Patterns of health care costs and tax payments for different income groups have an effect on the distribution of income.
- Average annual health care costs represent 24% of the income of the lowest income group ($4,220 of $17,500) but 3% of the highest income group’s average income ($3,350 of $114,900).
Although the corresponding tax payment amounts are much higher in high-income groups, in an average year over a lifetime, the lowest income group pays 6% of its income toward publicly funded health care services; the highest income group pays just less than 8%.
Lifetime average after-tax income in the highest income group is 5.1 times the income of the lowest group; after adding the dollar value of health care costs, the gap was reduced to 4.3 times.

Hopefully one day we'll have something similar for our country.

PS. Fyi - from BBC News.
The European Commission is launching legal action against Spain over the refusal of some hospitals to recognise the European Health Insurance Card.
The EHIC entitles EU citizens to free healthcare in public hospitals.
But some Spanish hospitals rejected the card and told tourists to reclaim the cost of treatment via their travel insurance, the Commission says.
A BBC correspondent says the Commission is not accusing cash-strapped Spanish hospitals of trying to make money. The Commission, which checks compliance with EU law, has requested information on the issue from the Spanish government - the first stage of an infringement procedure which could eventually result in a fine.

Navigating through data

The Health Data Navigator

Undertanding health system performance starts with the availability of data. Many sources are available, but beyond data you need a framework for the analysis. Since this week a new and healthful source is the Health Data Navigator, the outcome of the Euroreach research. The toolkit summarizes in one document the approach. It is a helpful resource. The institutional basis for performance is often a key neglected element in the analysis. They follow the WHO Building Blocks perspective, although there are other options.
Beyond OECD data, we have right now a new database to check. Unfortunately our country has not joined this initiative by now.

PS. The six building blocks:
• Good health services are those which deliver effective, safe, quality personal and non-personal health interventions to those that need them, when and where needed, with minimum waste of resources.
• A well-performing health workforce is one that works in ways that are responsive, fair and efficient to achieve the best health outcomes possible, given available resources and circumstances (i.e. there are sufficient staff, fairly distributed; they are competent, responsive and productive).
• A well-functioning health information system is one that ensures the production, analysis, dissemination and use of reliable and timely information on health determinants, health system performance and health status.
• A well-functioning health system ensures equitable access to essential medical products, vaccines and technologies of assured quality, safety, efficacy and cost-effectiveness, and their scientifically sound and cost-effective use.
• A good health financing system raises adequate funds for health, in ways that ensure people can use needed services, and are protected from financial catastrophe or
impoverishment associated with having to pay for them. It provides incentives for providers and users to be efficient.
• Leadership and governance involves ensuring strategic policy frameworks exist and are combined with effective oversight,coalition-building,regulation,attention to
system-design and accountability

Assesment and review

Disability weights in the Global Burden of Disease 2010: Unclear meaning and overstatement of international agreement

The Global Burden of Disease study is a huge effort to understand  worldwide population health. A former post explains some details and links. However, some calculations and estimates require and assessment and review. This is what Erik Nord explains in his article:

After a long history of changing concepts and methods in measuring ‘burden of disease’ the GBD 2010 has landed on ‘health’ as a unidimensional construct to be used forweighting multi-dimensional non-fatal health problems against each other and against death. At first glance this may look plausible. But the unidimensional health construct does not have a clear meaning. It likely also leads to biases in assessments of conditions that in everyday language are associated with ‘being ill’ as opposed to con-ditions which are not associated with ‘being ill’, namelystates of disability and the state dead. Furthermore, the transformation of ordinal data from paired comparisons into disability weights with purported ratio scale properties is not validated nor explained in a way that allows judgements of face validity.

And I would like to highlight this final consideration:

A value oriented burden of disease construct can either have a personal welfare content or a content that incorporates societal values in priority setting and resource allocation. Which of these would make the GBD enterprise most useful to decision makers is an important issue for further debate

I fully agree with this article. Aggregation without accurate metrics gives quick results, but uncertain for the implications we can derive, sometimes.

Death, taxes and fiscal deficit

Benjamin Franklin said: "The only things certain in life are death and taxes.". If he had lived here, he would have added "fiscal deficit" in its quote. And this is a constant since 1986, 8,1% of our GDP disappears and doesn't returns in services or infrastructures. And somebody is still interested in this money to use it for their preferences, and not for the tax-payers.
Yesterday we knew again that fiscal deficit was 16,543 million euros, a 8,5% of GDP of 2011. After 25 years, the accumulated amount of fiscal deficit is 306.267 million euros!!!. Can you imagine what represents this figure for a country of 7,5 million inhabitants?
Every year the fiscal deficit is equal to the sum of health, education and welfare expenditures. As far as a country can't survive with such bleeding, I'm convinced that we'll not discuss it again. Let's put it simply, time to say goodbye has arrived because it is socially unacceptable such discrimination and unfair relationship. Only one fourth of the fiscal deficit in one year would stop recent public budget cuts. The answer is only one: Goodbye.

Healthcare value chain, again

Redefining global health-care delivery

A remake of what you may already know has been published as article in The Lancet. It could be good as a reminder but something else is needed. The authors recognise:

Many individual elements we have described will be familiar to global health scholars and practitioners. Many lessons have been learned in discrete areas. What we lack is a true field. We need a clearing-house for information about programme design, best practices, lessons learned, synergies, policy constraints, environmental determinants, and other elements of global health-care delivery. In an age of information, the collection of data can run seamlessly from bedside to seminar room and back to the field.

 I'm uncertain about the outcome of such proposal. The details are so important and difficult to capture that the challenge is huge. On the other hand, I suggest to have a look at this Mckinsey Quarterly article that focus on the opposite: against benchmarking. After reading it, you'll notice that competition pressure in IT may not fit exactly with health care industry, and the message may not apply as straightforwarding.
Anyway, we need an evaluation effort to understand those strategies that are able to deliver more value. Now it's time.

PS. I wrote an earlier post about Porter et al.

Aprés tout (4)

An updated release of public health expenditure data has just been published. In 2011, the expenditure on health was 1,330 € per capita, you can check p.9 of the report. Total decentralised public expenditure: 10,120 m €, percentage of GDP: 5.1%. Why are these figures so different from my previous post with official data?
Now it seems that the deficit in 2011 was 932 m€ - a 10.1% budget deviation-, while formerly a lower figure was announced:586 m€. If it is a mistake, somebody has to fix it, otherwise it will remain in the statistics for the future. If it is true, then we have to ask why it was published incorrectly. Was it misinterpretation, negligence or making -up?

PS. Beware, this data comes from outside. Anyway, somebody has to confirm or dismiss it.

PS. Is it sustainable a public health expenditure variation from 4.4% of GDP to 9.9% of GDP between geographic areas with the same tax regime?

Economics of genomics

The Economics of Genomic Medicine - Workshop Summary

Just imagine for a while that you are concerned about economic implications of genomics and you invite a distinguished professor of genetic medicine - James Evans- to the introduction of a workshop at IOM. Instead of more is better, he sends a cautious message to the audience. And beyond the potential and valuable applications for those that are already ill,  he openly critizises the current trend towards the use of genetic tests for the healthy:

Assessing the risk of common diseases through whole genome analysis of a healthy person has received the most attention, but this attention “is somewhat misplaced,” Evans said. Currently, assessment of genetic risk alleles has “rather feeble predictive power” because the increased risks tend to be small. “From a clinical standpoint I don’t know what to do with patients who are at a 1.3 relative risk for colon cancer,” said Evans. “Am I going to hurt them by doing more intensive screening, or am I going to help them?”

"I know what almost everybody in this room is going to die of,” said Evans. “We are going to die of heart disease or cancer. . . . We are all at high risk for these maladies regardless of our [genomically determined] risk. And many at decreased risk for heart disease will still die of heart disease. So we are all going to benefit from interventions that lower heart disease. We don’t really need to target people. It doesn’t do anyone much good to tweak our estimation of an individual’s relative risk for common diseases which we are all at high absolute risk of developing anyway."

 “The old adage that an elephant for a nickel is only a bargain if you have a nickel and you need an elephant applies here. I am not sure most of us need that elephant. Even if free, perceived low cost is an illusion, because the misapplication of medical tests—and make no mistake, whole genome sequencing is a medical test—is very expensive,”

A clear message for geneto-enthusiasts and marketeers. Cost-effectiveness of genetic testing starts with assessing if they are effective. If not, any economic analysis is useless . This is obvious, but we do need to repeat it, just in case.

PS. Must read, Reinhardt's blog.

PS. A report to understand the financial markets' mess and why recovery is far by now.

The right rate

International Variations in a Selected Number of Surgical Procedures

If you want to be astonished by the huge variation on the rate of surgical procedures in OECD countries, have a look at this report. It is difficult to find arguments for such a huge differences in health care. The key statement:

The data presented here provide contemporary assessments of the size of the clinical margins of uncertainty for the procedures studied. These may also in part be a consequence of varying legal constraints, methods of payment, availability of cover and patient preferences. They therefore provide basic evidence for research priorities in an increasingly evidence-based medicine paradigm. The only way to make proper judgements on the optimal level for a particular procedure is to have national longitudinal data linking individuals’ treatment (and deliberate withholding of treatment) to outcomes. Such data do not exist in most countries. This is a critical deficiency in health service delivery, which means current policy on which procedures to fund, for whom, is formulated in circumstances based more upon local custom and scientific tradition than empirical effectiveness data.

Meanwhile you can add this report to the folders with the Atlas VPM that you may already know.

Tackling obesity

Integrating Educational, Environmental, and Behavioral Economic Strategies May Improve the  Effectiveness of Obesity Interventions

On top of the priorities for the improvement of public health, obesity deserves a place. However, the tools and decisions to slice its impact on health are still dubious. A recent article may help to put together different approaches:

Obesity is a multifactorial problem impacted by access to foods (supply) and food choices (demand). Neighborhood environments constrain the food choices available to individuals, while complex dietary decisions are driven by taste, cost, nutrition, convenience, and weight concerns. The complex nature of dietary choices therefore requires informed educational approaches that are strategically combined with guided nudges, and environmental interventions that improve access to promote healthier eating. Moreover, multi-institutional  collaborations will likely be necessary to address the obesity epidemic.

Since a multi-institutional approach is needed, somebody has to lead this effort. Is the government able to do it?. If so, don't delay it.

PS. Let me suggest also this Lancet article, my key reference up to now with the OECD one and its update.

The stratified approach

How Health Systems Could Avert 'Triple Fail' Events That Are Harmful, Are Costly,And Result In Poor Patient Satisfaction 

While reading the latest HA, I've picked this article that intends to focus on implementation issues: how to improve health. A short statement:

 The stratified approach to the Triple Aim described in this article includes three phases. A planning phase would involve conducting an opportunity analysis, developing predictive models and impactibility (also known as intervenability) models.

More details in the article. Formerly in this blog, I've explained more or less the same. For instance, have a look at a post of last year on risk prediction in a population . We do need to focus on the basics using the most appropriate tools. This is what the article does, and what we have to do.
