Philip Alcabes discusses myths of health, disease and risk.

A Must-Read Book

I urge you to stop what you’re doing and read Rebecca Skloot‘s The Immortal Life of Henrietta Lacks (Crown, 2010).   It’s a rare combination: clear reporting on how medical science works, insightful consideration of deep moral issues about the uses of human tissue for the advancement of knowledge, and a moving, often troubling, family narrative.

Henrietta Lacks died of cervical cancer in the “colored” ward at Johns Hopkins Hospital, in 1951.  From samples of her cervical tissue, the immortal cell line called HeLa was developed (by Dr. George Gey, at Hopkins).  Skloot’s story covers the family’s travails before and since, but also digs deep into the problem of race in the business of American medicine.  Her account challenges, or should move us to challenge, the smug certainties about our supposedly post-racial society, and the convenient formulae about “informed consent” and “access to care.” I guess I should say, The Immortal Life should make us ask just what “care” means in today’s system.

Henrietta Lacks and her family members were almost never taken seriously as humans with real problems.  First, they were poor and uneducated black people from tobacco country relocated to Baltimore; then, they were the bearers of the same genes as a woman (Henrietta) who had died of a remarkably aggressive, and therefore medically interesting, cancer; later, they were background and local color to the story of the origin of the thriving, and therefore scientifically interesting, HeLa cell line.

To Skloot’s credit, she’s taken to heart, and acted on, the problem:  she founded the Henrietta Lacks Foundation to help raise funds for education and medical expenses for Henrietta Lacks’s family.  Skloot’s blog, Culture Dish, carries updates about some of the achievements of the foundation and sometimes takes up issues germane to the book, especially regarding personal rights to genetic information (here, for instance).

It’s also impressive that Skloot interweaves in her narrative (and takes up more fully and explicitly in an Afterword) the vexing question of ownership of tissue samples.  She highlights how the expanding capacity to extract information from genetic sequencing ups the ante on the questions of privacy of tissue samples — since it’s now possible to ascertain potentially identifying information from genetic sequences even in a sample from which the usual verbal identifiers (name, address, and so forth) have been removed.  And she asks how the profits potentially available from exploitation of new discoveries should be shared.

The intersection of these problems with the matter of race makes The Immortal Life of Henrietta Lacks, like James Jones’s Bad Blood and Harriet Washington’s Medical Apartheid, a book that should be required reading for everyone involved in the health sector today.

Autism and the MMR Vaccine

There’s quite a furor this week over the British General Medical Council’s censure of Dr. Andrew Wakefield for his research at the Royal Free Hospital, purportedly showing a link between MMR (measles-mumps-rubella) immunization and autism (Lancet 1998; 351(9103): 637–41).

As New Scientist points out, the GMC’s finding removes any impediment to charging Wakefield and two of his colleagues with misconduct.  GMC may rule on that score in a few months, according to the BBC.

By and large, the talk about the verdict hasn’t been about the substance of the contentious vaccine-autism link.  At Autism Science Foundation, Alison Singer (the group’s president) writes that

Anti vaccine autism advocates continue to see Wakefield as a hero who remains willing to take on the establishment and fight for their children.  In the meantime, Wakefield’s actions have had a lasting negative effect on children’s health in that some people are still afraid of immunizations. In some cases, the younger siblings of children with autism are being denied life saving vaccines. This population of baby siblings, already at higher risk for developing autism, is now also being placed at risk for life threatening, vaccine preventable disease, despite mountains of scientific evidence indicating no link between vaccines and autism. This is the Wakefield legacy.

On the other side, Generation Rescue writes in support of Wakefield at Age of Autism.  GR isn’t as cogent as Singer, but brings up the point that tends to complicate this and most discussions of autism:    “Do you think pharmaceutical companies have too much influence in the laws, policies, and regulations of our government?  We do.”

Liz Ditz provides a great service, compiling blog posts pro-Wakefield and, separately, those criticizing Wakefield and/or supporting the GMC’s decision.  (As of today, the Wakefield critics seem to have been more prolific.)

Thursday’s BBC report concludes with a graphic showing a decline in MMR coverage in the UK between 1996-97, when it stood at around 90%, and 2004, when it bottomed at around 80%.  Superimposed is the number of measles cases, which increased from a few dozen in 2005 to over 1200 in 2008.  The implication is that Wakefield’s report was somehow responsible for the drop in coverage in the late ’90s and that that decline led to a sharp uptick in measles incidence.  The graphic also implies that after Lancet retracted the original paper in 2004, public acceptance of MMR vaccine improved after Wakefield had been repudiated — but too late to prevent the measles upsurge.

Without supporting Wakefield’s methods, it’s still worth asking whether his 1998 paper should be held accountable for the decline in vaccine acceptability.  As early as February 1998, England’s Communicable Disease Surveillance Centre was reporting on the drop in MMR coverage from 1996 and ’97 data and BMJ reported in 2003 that the British trend was consonant with declines in MMR uptake in Europe generally:

[T]he experts say that coverage is substandard across Europe owing to a surprising lack of political will to implement an effective disease prevention programme, given the region’s stated goal to eliminate measles by 2007.

A decline in nationwide vaccine coverage to 80%  is probably less important as an explanation for increasing measles incidence in the U.K. than two other factors:  locally deficient MMR coverage and immigration from countries with lower vaccination rates.  In fact, measles increases in the UK seem to have been attributable to outbreaks in the northern part of the country and to high incidences among very young children in London, according the UK’s Health Protection Agency.

What’s to be learned from the Wakefield mess?

1. The role of pharmaceutical companies (including vaccine makers) in setting scientific agendas and moving policy remains an issue for many people.  Defenders of Big Public Health, like Mark Honigsbaum who writes an interesting piece in The Guardian today, tend to be dismissive of allegations that public health has become a game for technocrats in which corporations have too much sway.  But the defenders misunderstand those critiques.  The critics are not saying that government predictions are wrong where they should be right, nor that officials are on the take; the critique is this:  the relationship between profit makers and public agencies is sometimes awfully cozy and the attentiveness to real suffering is remarkably slight.

2. The pre-eminence of ethics boards, like Britain’s GMC, doesn’t always sit well.  With the Wakefield case, the MMR-autism controversy steps onto the slippery terrain of moral decision making in regard to research.  Many people don’t feel perfectly reassured about the ethics of medical practice when the overseers are themselves physicians, and the moral reasoning often seems restricted to “did the physician follow the rules?”

3. The stance of official agencies on autism doesn’t inspire confidence.  Vaccination is hard to exonerate as a cause of autism as long as the official approach is that autism is a disease, and by implication preventable — rather than a disability, which might or might not have a cause but whose sufferers, in either case, can be afforded decent lives.  To make matters worse, official agencies’ stance doesn’t defuse the controversy.  In the U.S. and U.K., they respond to anti-immunization claims with assertions about the safety of MMR in particular.  But they don’t seem to want to support the research that would test whether some children might be susceptible to damage incurred cumulatively by undergoing the numerous vaccinations that are scheduled for children today.  It’s unlikely that the scrutiny of immunization, or the controversy, is going to go away unless officials soften that stance.

We’ll probably hear more on this if the GMC rules to disbar Wakefield from practicing medicine.

Revolving door? Official agencies and the private sector

In late December, Effect Measure reacted to former CDC director Dr. Julie Gerberding’s hiring as President of Merck Vaccines. With customary cogency and insight, Revere addresses the problem of the so-called Revolving Door.

At The Great Beyond, Daniel Cressey notes that Dr. Gerberding, while at CDC, was accused of promoting the Bush Administration’s agendas at the cost of scientific accuracy.  Naturally, now that she is heading for Merck, many are concerned about what looks like a cozy relationship between official agencies and pharmaceutical companies.

Merck says that its vaccine arm is worth $5 billion.  It “markets vaccines for 12 of the 17 diseases for which the U.S. Advisory Committee for Immunization Practices currently recommends vaccines,” according to the company’s press release.

Dr. Gerberding was close to the vaccine world as head of CDC. In fact, during her tenure there CDC’s   Advisory Committee on Immunization Practices (ACIP) called for the implementation of immunization against human papillomavirus and varicella zoster (chicken pox) virus and the agency pushed for expanded immunization against seasonal flu; within 10 months of her (January ’09) departure from CDC, the ACIP had issued recommendations for the use of anthrax vaccine and Cervarix and Gardasil vaccines against HPV.  Gardasil  is a Merck product.

But the problem is more than the “revolving door” metaphor implies.  To have a door there must be a wall — a clear demarcation between inside and out.   As if corporations (pharmaceutical companies among them) were outside of the official system, eager to get the ear of those inside.

Whereas it seems that there isn’t really much of a wall between official health agencies and big business at all.  To be an official today means taking a veritable oath of loyalty to corporate solutions.  The official has to deal in risk.  She has to be ready to sell risk as a kind of debt:  people should want to avoid risk, just as they avoid debt; but if their behaviors put them “at risk,” they can relieve it through “lifestyle” correction.  You can refinance if you know how.

The correction that allegedly relieves risk usually involves the use of better products. Cut out trans fats,  lower your cholesterol, elevate your mood, hop on a treadmill, lose weight, drink responsibly, get seasonal flu vaccine, get swine flu vaccine, wait patiently while the full-body scanners are used at the airport, eat more vegetables, wear sunblock, use hand sanitizer.  Health officials’ job is to get the means for personal risk reduction to the sorry at-risk population.  Have hand-sanitizer dispensers installed in public buildings.  Distribute condoms.  Publish recipes for healthy meals.

Notably, health officials are not supposed to argue for any of the things that would actually make a difference to the public’s overall health:  redress wealth disparities, provide excellent primary care for everyone (including immigrants), or build more decent and affordable housing.  When was the last time you heard a health official call for a campaign against poverty?

The official has to pitch personal risk reduction, in other words.  She has to be ready to support high-cost, individualized approaches to improving the public’s health — or well-being, which, Dr. Michael Fitzpatrick astutely notes at Spiked!, has replaced health as the main objective of modern Good Works .

Health officials keep faith with the dogma of risk avoidance.  Corporations preach risk reduction and peddle the wares by which people can restructure their lives — and avoid risk.  The wall separating government policy makers from corporate solutions gets more and more flimsy.

The “Deadly Choices” Report

Sheri Fink’s thoughtful and masterfully composed “Deadly Choices” report discusses the death of patients at New Orleans’ Memorial Medical Center (MMC) in the days after Hurricane Katrina in 2005 (additional material is at ProPublica).

“Deadly Choices” is heartbreaking.  It recounts a situation that was miserable, terrifying, and in some cases, fatal.  Fink reports that, among 45 Memorial Medical Center patients who died in the days during and immediately following the storm, 17 were deliberately administered lethal doses of morphine, sometimes along with a sedative, by physicians who apparently intended to hasten the patients’ deaths.  (Many of these 17 were patients at a hospital-within-the-hospital, a long-term care hospital under separate ownership that shared some staff with MMC.  At Slate today, Josh Levin discusses some of the troubling truths about the financing of long-term care hospitals, and Fink fills in some more of the blanks with a response at ProPublica.)

As Fink explained to Amy Goodman in an interview with Democracy Now earlier this week, at least one of the patients who were killed was not in extremis; he had not given up.  He was

“Ready to rock and roll, wanted to get out. And apparently, according to several people who later spoke with investigators, a discussion was had in which they talked about how they might get him out, and they decided that because he was so heavy and it was so hot and people had—I mean, just imagine….They had been going on no sleep for days, the medical workers. They were tired. They were terribly disturbed by all the suffering that they felt that they saw around them. And so, in this sort of moment, they apparently decided that [the patient] could not be brought down, could not be evacuated, that there was no way to get him out.”

The story of what happened at MMC is also profoundly disturbing.  It moves us to ask what sort of moral world physicians are expected, and allowed, to operate in.  And to wonder why moral boundaries should be so elusive to exactly the people who, with access to the means to both prolong life and hasten death, walk on morally fraught territory more often than anyone.

The horrifying events at MMC are especially  germane today — because they highlight a vexing question about health care reform that is very hard to answer:   Is our doctors’ job to alleviate suffering, or is it to improve health?

A favored guru on health care ethics, Ezekiel Emanuel, is explicitly in favor of the latter.  In “Justice and Managed Care” (subscription) in Hastings Center Report in 2000, he writes

“The allocation of health care resources should aim at and be justified by the improvement in people’s health…. The special aim or purpose of health care is curing disease, relieving pain and suffering, promoting public health, pursuing research to improve health, and so on.”

The “and so on” means that improving health — the obligation of a health care system, Emanuel asserts — amounts not just to the relief of pain and suffering but also to research and public health, and other tasks as well.  The relief of suffering might not be a priority, that is.  Or it might be a contingent priority, of importance for a limited time, or in certain circumstances — but not the only thing to worry about.

The point is not to vilify Emanuel.  He has opposed euthanasia and physician-assisted suicide, so we should assume that he was as appalled by the actions of the chief physicians at MMC as others were.

But the Emanuelian sensibility is that the system in which physicians work is not meant to be dedicated to the relief of suffering alone.  Rather, it bears other duties as well:  a broad obligation to the public to promote health, and another obligation to contribute (through research) to the future of health care.

In this narrative, the physician is marshal of a campaign — not merely joined in a series of caring relationships with each of a number of patients, but commander of troops who have a long-term goal and territory to win.   By implication, the rights of patients might take second seat to the needs of the public, or to the desire to learn more about how to improve health in the future.  Patients shouldn’t be killed, this thinking goes, but they will have to understand that the prolongation of life is a luxury commodity to which physicians have the keys — and not everyone can have access.

The sense of the physician as a responsible manager, not merely a giver of care, connects with the utilitarian credo, “the greatest good for the greatest number” — a phrase that occurs three times in Fink’s piece as she strives to characterize the sensibility of MMC providers.

But the killings at MMC should, at the very least, make us ask whether it’s a good idea to have doctors making decisions about the greater good — or whether we want them to recognize individual persons above all.

Bodies Using Bodies

Larissa MacFarquhar’s article on kidney donation in the July 27th New Yorker reminds us that our society remains uncomfortable about the satisfying of bodily needs by making use of other people’s bodies.

This is a good discomfort, no?  Nobody should blithely take advantage of another person, coercing him into donating his organs or making use of her for sexual pleasure without consent.  Watching Stephen Frears’s 2002 film Dirty Pretty Things leaves you appalled and angry at the kidneys-for-passports trade, as it must.  Slavery is an outrage and an offense, a rejection of the values that make ours a civilized society.   Every thinking person decries the trafficking of women for sex.   In modern society, it feels wrong when one person’s body is used to  advantage another’s body.

The exchange of money in the process seems to change the moral valences without exactly alleviating the discomfort.  That children’s families are paid for their manual labor in processing cocoa for the chocolate we eat doesn’t make the practice of child forced labor seem less heinous.  Maybe we even boycott chocolate manufacturers who use chocolate from Ivory Coast, where child labor is involved.  Taking advantage of children’s bodies disturbs us (even to the point of limiting our chocolate purchases).

Money registers differently when it comes to adult sexual exchange.  In the usual American view, there is a bright line between sexual enjoyment obtained through the use or threat of force, and the same enjoyment procured by payment but without force.   Both forcible rape and prostitution are illegal, but most people would recognize a distinct difference between the moral repugnance elicited by rape and the tinge of moral corruption carried by sexual advantage obtained by payment.

Payment introduces a legal twist to sex, too:  the law holds the man who procured sexual advantage through force to be culpable in the act of rape.  Yet, when it comes to paid sex, the legal code holds the woman who provided the sexual service accountable.  The bluenose might scorn both the sex worker and her client equally, but the law makes a distinction.

By contrast, payment makes all the difference when it comes to the use of someone else’s body for productive manual labor.  Your neighbors would be repelled if you were to use force to make a passer-by reshingle the roof of your house, and might have you arrested.  But they aren’t bothered when you hire a roofer.  Most aren’t very bothered when the roofer has some immigrant laborers do the scut work for below-minimum wage — which seems someplace in between a true fee-for-service contract (you in need of a new roof, a roofer able to build one) and slavery.  When money changes hands, it softens the moral impact of making use of someone else’s body.

But the moral flavor doesn’t disappear.  If your roofer refused to let his immigrant workers come down off the roof during a lightning storm, his meager payments to his workers would feel less important than his endangering their welfare.   In other words, onlookers would still be moved by the moral flavor involved in making use of someone else’s body.

Now for the tricky part. What about the use of others’ bodies for medical research? An article in today’s Times laments the shortage of willing bodies for testing cancer treatments.  Contemporary medical ethics presupposes a human trait called “autonomy” and requires that researchers respect this characteristic – for instance by refusing to experiment on a person unless she has signed a consent form acknowledging that she agrees to be experimented on and asserting that she understands the risks and rewards involved.

Of course, the reward system is often obscure, no matter how verbose the researchers are in the process of obtaining consent – in part because it’s often hard to predict who will benefit if new treatments are deemed to be effective, in part because it’s often hard to know how effective a treatment is likely to be, and in part because a big chunk of the benefit accrues to the researchers (articles published, grants funded, awards won) and the research industry (grant funding justified, administrative costs rationalized).

Nobody would accept a system in which people are forced to become medical research subjects.  In fact, the discoveries at Nuremberg about forced participation in medical experiments during the Second World War gave the impetus to the modern field of medical ethics.

But how much does it change the moral outlook if you are rewarded for allowing your body to be used by medical researchers with a cash payment?  The researcher has to be able to claim that her  subjects are not forced to participate – and the medical ethicists who are attached to the autonomy concept will still worry that the subject’s decision to lend his body for research will be coerced, not free and autonomous, if the payment is too grand.

For some classes of people, including children and addicts, payment is deemed to be especially coercive.  The thinking being that if the researcher were to offer $100  to an addict, the addict would use it to buy dope, and that would be harmful, and therefore the researcher would be doing a bad thing even though her research was really meant to do good.   Physician researchers always need to feel that they’re doing a favor to society (not to themselves).

Meanwhile, others decry payments that are too small, arguing that time, angst, and (sometimes) physical or mental suffering involved in being a research subject ought to be reimbursed at respectable rates.   Although the idea of a professional workforce of permanent research subjects, who might receive a retainer in return for surrendering their bodies and tissues for research, rubs physician researchers the wrong way.

Our society really likes medical research. We don’t want our doctors to stop looking for ways to help us to live longer and more comfortably.   Bodies must be used, but they shouldn’t be used without consent, they shouldn’t be purchased outright (that would be slavery), they can’t be paid too much, they shouldn’t be paid nothing, they shouldn’t be recruited for research use in perpetuity or receive the sort of ancillary benefits of employment that professionals get, and they should preferably not be “vulnerable” (young, developmentally disabled, imprisoned, or pregnant).

Which brings us back to kidney donation.  Should kidneys only be allocated anonymously and through a universal system that provides kidneys in accord with a complex algorithm that takes account of the likely benefit of the transplant?  Should there be a federally controlled market in kidneys, or at least some system that encourages donors through market-value incentives (like tax breaks), as Sally Satel has advocated?  Should there be a fully open market through which you could purchase the organ you need from a suitable and willing donor?

The conjunction of bodies-in-service-to-other-bodies and dollars makes the kidney question — like sex work, child labor, and medical research — fraught with moral meanings.  Simple solutions won’t serve.
