Michael Marmot, the British Medical Association, and the Social Determinants of Health

.

The social determinants of health are real and profound. They are the aspects of life outside the medical office and hospital, outside of drugs and surgery, that affect our health. Income differences, education differences, and differences in social cohesion, to name a few, have been extensively described in the literature and have even made some headway in the medical curriculum at many schools. Addressing health disparities is a major focus of our Healthy People 2020 effort. Recognizing and addressing the social determinants of health has been, and will continue to be, the primary focus of this blog. A few recent posts addressing this topic include Healthful Behaviors: Why do people adopt them? Or not? October 8, 2011 and "Health in All" policies to eliminate health disparities are a real answer, August 18, 2011, and a little longer ago, Social Determinants, Personal Responsibility, and Health System Outcomes, September 12, 2010.

Some of the most important work in the area of social determinants of health has been done by the British physician and epidemiologist Sir Michael Marmot, whose “Whitehall” studies, begun decades ago, showed that health status was associated with socioeconomic class. He has continued this with his recent work “Fair Society, Health Lives”[1]. Thus, it should not come as a surprise that it was under Dr. Marmot’s recently-completed tenure as President that the British Medical Association (BMA) issued its report “Social Determinants of Health: What Doctors Can Do”, in October 2011. It is more interesting that Dr. Marmot, in his introduction to the report, notes that “ … as I mentioned in my presidency acceptance speech, I was surprised at being approached to be president at all,” because “My work has been focused on inequalities in health where I have emphasised the circumstances in which people are born, grow, live, work, and age rather than anything specifically to do with health care provision. I have emphasised not just the causes of health inequalities—behaviours, biological risk factors—but the causes of the causes. The causes of the causes reside in the social and economic arrangements of society: the social  determinants of health. More than that though more recently my work has looked at what can be done to address these issues across the life-course.”

Many of us in medicine, even on this side of the Atlantic, were thrilled that the BMA had chosen Dr. Marmot as its president precisely for these reasons. The current report shows that this was well-placed enthusiasm, for it marks a the commitment of the BMA to improving the health of the British population even, and perhaps especially, when that requires physicians to work outside of their “usual” venues. That is, when the work requires collaboration with other professionals, particularly educators but also social service agencies, to be effective. And to exercise their roles as community leaders, not simply purveyors of drugs, operations, and individual advice: “We recognise that not every doctor has the opportunity to change the social determinants of health throughout the life course of individual patients and have thus included other ways in which they can make a difference, as doctors working as community leaders.”

“Social Determinants of Health: What Doctors Can Do” presents conceptual models and large-scale goals, as well as principled statements of how physicians must act to create conditions of social justice and reduce the gradient of health disparity that results from different life circumstance. For example, it takes from “Fair Society, Healthy Lives” the following set of policy objectives that physicians and their organizations should work towards:

A - Give every child the best start in life

B - Enable all children, young people and adults to maximise their capabilities and have

control over their lives

C - Create fair employment and good work for all

D - Ensure healthy standard of living for all

E - Create and develop healthy and sustainable places and communities

F - Strengthen the role and impact of ill health prevention

          (These are expanded upon in “Annex A”, beginning on p. 26)

However, the paper goes beyond these generalities and provides specific examples of programs that have been and are in place in different communities across Britain that have made an impact on these areas. The BMA commits that they “will keep examples of effective actions on our website, and encourage the World Medical Association to garner international examples, to aid doctors seeking ways to make a difference.” One example of this two-phased approach of identifying the problems and seeking examples of solution is in “The Health Impacts of Cold Homes and Fuel Poverty report”, whose main findings of direct impacts included:

          - Countries which have more energy efficient housing have lower excess winter deaths (EWDs).

          - EWDs are almost three times higher in the coldest quarter of housing that in the warmest quarter.

          - Around 40% of EWDs are attributable to cardiovascular diseases.

          - Around 33% of EWDs are attributable to respiratory diseases.

          - Mental health is negatively affected by fuel poverty and cold housing for any age group.

          - Cold housing increases the level of minor illnesses such as colds and flu and exacerbates existing conditions such as arthritis and rheumatism.

          - Cold housing negatively affects dexterity and increases the risk of accidents and injuries in the home.

Main findings of indirect impacts:

- Cold housing negatively affects children’s educational attainment, emotional well-being and resilience.

- Fuel poverty negatively affects dietary opportunities and choices.

- Investing in the energy efficiency of housing can help stimulate the labour market and economy, as well as creating opportunities for skilling up the construction workforce.”

They then describe a program in Manchester that is working to addresses this problem.

Another intervention is occurring in an impoverished part of England, where the “Bromley-by-Bow Centre aims to serve the local community by providing a wide range ofservices and activities, which are integrated and co-operative in nature. They host the local GP surgery, a variety of social enterprises, a children’s centre, artists’ studios, a healthy living centre, and provide adult education courses, care and health services for vulnerable adults, outreach programmes and a range of advice services. This approach enables GPs to refer patients to services that help to tackle the social determinants of ill health, including welfare, employment, housing and debt advice services.”

A society can never achieve a significant improvement in health, or decrease health disparities, unless it consciously and forthrightly addresses the social determinants of health. Physicians can be leaders in this effort, or they can sit comfortably in their offices and hospitals tending to the individual health problems of people that could have been prevented before. Dr. Marmot says  

“During my tenure I have been struck, but not surprised, by members’ utter commitment to

improving the health, not just of individual patients, but of society as a whole….As the year progressed I could see more and more how my tenure at the BMA and my work on the social determinants of health were a perfect fit. Time after time I was faced with examples where doctors were working tirelessly to increase fairness and social justice by acting on the social determinants of health to reduce health inequalities.”

That makes me proud of my colleagues in Britain and in the BMA, but these are also characteristics of many doctors in the US. And of many medical students, who are driven by their desire to make a difference. The US is not the UK (we don’t, for one really big example, have a national health service or even a national health insurance program!), but we have real needs and real caring people, including physicians. We just need to keep focused on health and how to improve it and not be dissuaded by tangential issues. We need to maintain the energy and idealism of medical students and ensure that it grows, rather than withers, thoughout their careers.

Poverty, Primary Care and the Cost of Medical Care

.

On January 27, 2010 (Health is more than Medical Care) I discussed how the concept in the title of that piece is true. A society that does not provide for the basic needs of its citizens, such as the US, is going to have more sick poor people who end up requiring more health care services at much greater cost. The greater the income disparity in a country, the greater the negative impact of poor population health. Countries that have a national health system can mitigate some of these effects by, at least, providing access to care for those who, through the various negative effects of poverty, suffer the worst health, but they do not prevent it.

This point is illustrated in the latest (of many, over the years and decades) reports on health status in the United Kingdom, commissioned by the government and done by a panel headed by Sir Michael Marmot of the University College – London. The report, “Fair Society, Healthy Lives”, documents the cost to the National Health Service of the ill health of the poor. This is not, of course, news; Marmot’s famous Whitehall studies demonstrate that there is a more or less linear correlation between health (including longevity) and increasing social class; it shows that the problems have not been resolved. In countries with less disparity of wealth and income (class) than the UK, including most of Scandinavia, these disparities in health are less; in the US, where the disparities in wealth and income are greater, so are the disparities in health and their associated cost.

Since, in the US, poor people are more likely to be uninsured (or have Medicare, if they are over 65), their health care costs are largely borne by the public sector. In this sense, the costs of Medicare can, and have, been used as markers for the overall cost of medical care. This assumption has a great deal of validity, because Medicare recipients, the “aged, blind, and disabled”, are highly overrepresented in both the middle and high use segments of the population (see Red, Blue, and Purple: The Math of Health Care Spending, October 20, 2009). (It is, however, important to remember that the majority of the 5% of “highest cost” users are not seniors – they include NICU babies, multiple trauma victims, and cancer patients.) The publications of the Dartmouth Atlas of Health Care have demonstrated much geographic variation in cost, and these have been used by a large number of health economist and scholars, as well as the Obama administration, to suggest that a great deal of health spending could be avoided if the “high cost” regions utilized health resources at the same rate as the lower cost areas.

Not everyone agrees with the Dartmouth analysis. Probably their most prominent critic is Dr. Richard Cooper of the University of Pennsylvania’s Wharton School, whose positions I have previously discussed on several occasions (most recently January 7, 2010, Primary Care and Residency Expansion). On his blog, Physicians and Health Care Reform, and in venues such as the on-line public health discussion group “Spirit of 1848”, Dr. Cooper argues that it is poverty rather than “inappropriate” use of health services that drive the differences in Medicare spending in different regions. He illustrates this by maps showing the far greater density of poverty in “high cost” Los Angeles, Miami, and Birmingham, AL compared to “low cost” Rochester, MN, Grand Junction, CO, and Portland, OR.

Many others disagree with Dr. Cooper, not in the sense that they feel that poverty is not a (or the) major determinant of health status, but with his assertion that the cost variations the Dartmouth Atlas identifies are solely an artifact based on prevalence of poverty. Among the most prominent of these critics is Dr. Barbara Starfield, of the Johns Hopkins University, a major health services researcher whom I have also often cited. I believe that Cooper’s argument that the Upper Midwest is richer, and thus healthier, than the Southeast is relying on areas that are too large. His contrasts of the cities above in terms of their concentrations of poverty are accurate, but the argument misses the tremendous difference (cited by Dr. Atul Gawande in his piece “The Cost Conundrum” and its followup “The Cost Conundrum Redux” in the New Yorker) between cities such as McAllen and El Paso, TX. Or, for that matter, between Los Angeles and San Francisco, or Chicago, all of which have varying levels of health costs (i.e., Medicare spending).

The real issue is “what is the implication of either position, or any other, for what to do to address the health needs, and cost of medical care, for the US population?” From much of his previous writing, Dr. Cooper has disparaged the contribution of primary care prevalence to the quality of health care, seeing it as a confounder to the true cause of higher spending, because it is more prevalent in the Upper Midwest than in the high cost areas. The data, from many, many studies in many, many countries, not only those by Starfield and the Dartmouth folks, is that it is not a confounder. Where health systems are built on primary care costs are lower and, more important, quality is higher. This should not be a surprise to anyone who is concerned about the impact of poverty on health status – when poor people can access preventive services and treatment at an earlier stage, where intervention is both less costly and more effective, they will have better health status. Primary care reduces cost.

Hospitals and many subspecialist physicians are not happy about the potential for cuts in Medicare because they already think that Medicare spends too little. That is, it does not pay “enough” for the extraordinarily costly high-tech interventions that they make their profit on. I suggest that Medicare spends too much on this kind of care, rather than paying a lot more for the preventive and primary care services that would make this kind of tertiary intervention necessary less often. Medicare should not simply make revisions to its payment schedule, it should completely turn it on its head so that a day of managing multiple complex medical and social problems and doing preventive care by a primary care doctor generates more money than a day of doing procedures such as endoscopies, catheterizations, and the like. (Note that I am not suggesting we invert the incomes, just the amount that these doctors earn relative to each other; the net cost should be dramatically reduced.)

This would, of course, encourage more medical students to enter primary care, which would be a good thing for the health of us all. Simply increasing the number of funded-by-Medicare residency positions will not do that, but rather would just generate more hoping-for-high-income sub- and sub-subspecialists, whose overall effect on health status is, from a population perspective, small. (For example, I benefit, for sure, if my brain tumor is excised or my cerebral bleed drained, and I definitely want access to its benefit, for me and you and the poor; however, if there were no neurosurgery at all, the impact on the health status of populations would be minimal.)

More important, it would free up a lot more money for addressing the overall social problems of poverty, while now the cost of medical care, exceeding 17.3% of the GDP (CMS report by Truffer CJ, et al, in Health Affairs, February 4, 2010) threatens to choke off any other social spending. As articulately stated by Bob Phillips of the Graham Center (personal communication), giving the “…poor the same access to excess that all of the rest of us have in order to lift them from disparity would only hurt them more. Economically, health care is starving the services that do help reduce disparities--education, social services, day care, Head Start, food stamps, etc. They are all suffering right now in state budgets because healthcare is devouring state budgets (health care consumed 1/3rd of all fed/state tax dollar s in 2008,[1] (and probably more now that tax revenue is down)”. This is demonstrated by the 2005 study by Boston University’s Sager and Socolar[2] and shown in the attached graphic, from the Graham Center’s presentation on the topic. Obviously, there would still need to be a decision by our society to spend the savings on social services (rather than, say, tax rebates to the wealthiest Americans, or war), but, other than war, there is hardly a less useful way to improve the health status of the poor than by spending it on more high cost tertiary and quarternary care medical centers staffed by more and more sub-sub-specialists.
