I think that Nationalized Health is an excellent idea that is devilishly hard to implement.
As one might imagine, people out there make a living studying this subject. A quasi-neutral view is available from the UN’s World Health Report 2000 Chapter 2(200 kb pdf).
Part of the difficulty in this discussion is that we are talking about assessing a health system as good/bad, 70% vs. 90%, and the like. The UN report above contains some ideas that will help in that regard. The first is:
[QUOTE=World Health Report 2000 Ch. 2]
To assess a health system, one must measure five things: the overall level of health; the distribution of health in the population; the overall level of responsiveness; the distribution of responsiveness; and the distribution of financial contribution.
[/QUOTE]
One single measurement is meaningless. We can’t say that one system is “good” or “bad”. Each one scores differently on each of the UN’s five scales.
Further on in the text, “responsiveness” is defined:
[QUOTE=ibid]
Responsiveness is not a measure of how the system responds to health needs, which shows up in health outcomes, but of how the system performs relative to non-health aspects, meeting or not meeting a population’s expectations of how it should be treated by providers of prevention, care or non-personal services.
[/QUOTE]
So far, so good. Where it gets interesting is in the statistical annex(400k pdf).
Here’s Table 9:
[QUOTE=WHR2000 Annex]
Overall health system attainment is presented in Annex Table 9. This composite measure of achievement in the level of health, the distribution of health, the level of responsiveness, the distribution of responsiveness and fairness of financial contribution has been constructed based on weights derived from the survey of over one thousand public health practitioners from over 100 countries.22 The composite is constructed on a scale from 0 to 100, the maximum value. As explained in Box 2.4, the weights on the five components are 25% level of health, 25% distribution of health, 12.5% level of responsiveness, 12.5% distribution of responsiveness and 25% fairness of financial contribution.
[/QUOTE]
Now, I have some problems with their changing the names, and calling a “distribution of financial contribution score” a “fairness score”, and I can think of improvements in the way that they rate responsiveness, but hey, it’s the best we’ve got.
This is a composite measure of how well countries meet the health needs of their populations. It gives a score from zero to one hundred, with one hundred representing the top score on all five scales. Here’s the results:
Japan 93.4
Switzerland 92.2
Norway 92.2
Sweden 92.0
Luxembourg 92.0
France 91.9
Canada 91.7
Netherlands 91.6
United Kingdom 91.6
Austria 91.5
Italy 91.4
Australia 91.3
Belgium 91.3
Germany 91.3
United States of America 91.1
Japan is the clear outlier, perhaps because of its extremely heterogeneous population. What I found interesting was that the top fifteen countries were only separated by a couple percent, and excluding Japan, by 1%…
This means that those countries do about as good a job as can be done. Switching to a national health care system will not improve the overall level of care. This is not good news, because from there, the only way is down. We can’t go up much.
Now, all of the different countries scored differently on the various individual measures that go into the final composite score. The NHS systems, as you might imagine, scored higher on the “fairness of contribution” scale. Here’s what the UN says about that scale:
[QUOTE=ibid Ch. 2]
Fair financing in health systems means that the risks each household faces due to the costs of the health system are distributed according to ability to pay rather than to the risk of illness: a fairly financed system ensures financial protection for everyone.
[/QUOTE]
You recall I said I had problems with this. Mostly, it’s the assumption that one system is “fair” and the other is “unfair”. A fair name for what is being measured was in the quote from Chapter 2. There it is called the “distribution of financial contribution”. In reality, it is just a scale. At the high scoring end, everyone pays based on income and sick people use the service more. At the low scoring end, people pay based on their state of health and sick people use the service more. I can make a reasoned and cogent argument for both sides being fair. One argument goes “Why should I have to pay thousands of dollars to treat a life-long smoker for emphysema? That’s their problem.” The other argument goes “You pay for a policeman whether you need him or not. How is this different?” I’m not advocating for one or the other, not even sure which one I’d pick.
I note also that of the five measures, only the first four have to do with the actual health care delivered. The “fairness” score is the only non-medical score of the five.
Now here’s a statistical oddity for you. As you might expect, on the “fairness” scale, the US scores way down in the middle of the pack, way behind the NHS countries. Since it is within a percent of all the top performers (all of which but the US are NHS countries) on the composite score, this means it is in the middle of pack regarding the health-related part of the composite score.
This is a strange thing. It means that in some sense, health care at the top of the heap is close to a zero sum game. You can up the responsiveness, say, but some other aspect will likely suffer. Curious. This suggests that if the US changes to an NHS (which will dramatically increase our “fairness” score), it is probable that some combination of the level of health, the distribution of health, the responsiveness, and the distribution of responsiveness of the health system will decline. Hmmm … kinda makes sense in a world of limited resources, where all of those aspects of the actual health services costs money. More to one … less to another.
Finally, we know that the per capita expenditure of the US is high compared to the NHS countries. We also know that our actual health care score (the four actual measurements of the health care system) are right up there with the highest in the world. So in theory, and I emphasize in theory, there are some potential monetary savings to be had.
So my conclusions from all of this are:
-
The possible improvements are thin. There is not a whole lot of head room from where we are. A change to an NHS system is extremely unlikely to improve our actual delivery of health care by more than a percent or so. However, it could easily decline from the changeover. That’s called downside risk, usually thought of as a bad thing.
-
Theoretically there is money to be saved. However, it may result in poorer care.
-
There’s not a whole lot of money to be saved. We spend about 13% of our GDP on health care, versus about 10% in most of the OECD NHS countries. It’s money, but it’s not game-changing money.
Finally, you have to factor in the people’s opinion of the Government. In the US, cheating the government is a national pastime. For historical reasons of the geography and development of the country, there is a general sense of the government as something far away, and when you see them you’re in trouble of some kind. Getting one over on the Government is seen as a good thing. Dodging the tax man, hiding your moonshine still from the Revenuers, smuggling whiskey during Prohibition, doing cash transactions to avoid sales tax, that’s the national religion.
Partly as a result of this, our Medicare/Medicaid system is shot through with overbilling and fraud. People figure they’re not really cheating anyone, it’s just the Government.
Which of course means that we may never see a penny of the theoretical savings possible from the changeover. And it is certainly possible that it could cost more than the current system. The precedent of the US experiment with Medicare/Medicaid is not encouraging in that regard.
So at the end, I figure it all boils down to the question of how we distribute the costs. If you think you shouldn’t pay for medical treatment for smokers and junkies, you go one way. If you think everyone is entitled to health care as a basic right in a modern society, you go the other way.
Because the total cost of the system, and the medical treatment of the system, near as I can tell, probably won’t change a whole lot. Other than changeover costs (which could be high, not something I’d want to take on today), we’d likely pay somewhere near the same amount, for somewhere near the same standard of care. The only difference is how the costs are to be assessed.
At the end, I think it is worth the experiment. I say this because despite what the numbers say, the medical system in the US is falling apart. American health care is good, but it can’t last. My wife is a Nurse Practitioner, so I’ve watched the change over the last thirty years. Doctors are going broke, hospitals are going broke, malpractice insurance is through the roof. A number of areas don’t have obstetricians, because they have been driven out by lawsuits. So overall, well, NHS can’t be too much worse, and might be better.
The World Health Report 2000 is a fascinating document. I encourage people to read it.
