Why medicine is not a science and health care is not health

MicroscopeHere’s something I read recently in a blog post (The Limits of (Neuro)science at Neuroskeptic) that started me thinking:

Will science ever understand the brain? …

The notion that humans are complex and hard, while nature is easy, is an illusion created (ironically) by the successes of reductionist science. Some of the biggest questions facing mankind for eons have [been] answered so well, that we don’t even see them as questions. Why do people get sick? Bacteria and viruses. Why does the sun shine? Nuclear fusion. Easy.

I started to write a simple reply, but it grew into the following.

Medicine is an applied science, not a pure science

It may be true that understanding the human brain is only an order of magnitude more difficult than understanding any other aspect of human biology. I’m uneasy, however, about putting ‘why people get sick’ in the same category as ‘nuclear fusion.’ Particle physics is a science. Questions can be asked and (usually) answered under the controlled conditions required by the objectivity that characterizes science.

Medicine is the application of certain sciences (molecular biology, biochemistry, medical physics, histology, cytology, genetics, pharmacology, neuroscience) to – ultimately — individuals. Each individual is the product of a unique, lifelong sequence of social, cultural, economic, and psychological (as well as physical, chemical, biological, and genetic) influences. To this day, we don’t really know why some people get sick and others do not. To my mind, that makes medicine an application of science – like engineering – not a science in itself.

Recommended (online) reading

Woman reading computerI’m still on “sabbatical.” Mostly reading. Thinking about what I most want to write about. I know what my interests are — the problem is, I have too many. Meanwhile, here are some blogs I enjoy reading.

Thought Broadcast by Dr. Steve Balt

Psychiatry is a controversial topic these days. We (speaking for myself, anyway) love to criticize the overprescription of psychopharmaceuticals, the medicalization of the slightest deviation from “normal,” and those psychiatrists who are eager to take “gifts” from the drug companies whose products they subsequently prescribe and promote.

I suspect people relate to psychiatry more readily than to the science of medicine. We’ve all known moments of slippage along the spectrum of mental health. We’d all like to understand ourselves better, something psychiatry used to promise before it tried to reduce us to the chemical interactions inside our brains.

Dr. Balt writes about all of this. What I especially like about his blog is his compassion for patients and his honest assessment of the psychiatric profession. His writing has a quality like Gawande’s: He maintains a strong personal presence without straying too far into the overtly personal.

To get a sense of Thought Broadcast, read Dr. Balt’s My Philosophy page. A recent post I’d recommend: How to Retire at Age 27. It’s on psychiatric qualification for disability. His point is that labeling (and medicating) someone as disabled does nothing to solve underlying social problems. It concludes:

Psychiatry should not be a tool for social justice. … Using psychiatric labels to help patients obtain taxpayers’ money, unless absolutely necessary and legitimate, is wasteful and dishonest. More importantly, it harms the very souls we have pledged an oath to protect.

When the poor were contagious

Unsanitary living conditions 19th centuryThe Western world first industrialized in Great Britain, prompting vast numbers of inhabitants to move from the agricultural countryside to urban centers. Living and working conditions were deplorable. Andrew Mearn wrote in 1883 of the “pestilential human rookeries … where tens of thousands are crowded.” He continues:

To get to them you have to penetrate courts reeking with poisonous and malodorous gases arising from accumulations of sewage and refuse scattered in all directions and often flowing beneath your feet; courts, many of them which the sun never penetrates, which are never visited by a breath of fresh air, and which rarely know the virtues of a drop of cleansing water…. You have to grope your way along dark and filthy passages swarming with vermin. Then, if you are not driven back by the intolerable stench, you may gain admittance to the dens in which these thousands of beings who belong, as much as you, to the race for whom Christ died, herd together.

Pretty graphic. Roy Porter’s comment on this passage: “Historians still dispute whether industrialization raised or depressed wages and living standards – something, perhaps, impossible to measure.”

On sabbatical

Self-reflectionI’m taking a break from frequent blogging – want to take time to read, do some research, reflect, and think about what I most want to write about next. At the moment, my inclination is to write about the history of medicine, starting with the Enlightenment and the transformation of medicine into a science in the 19th century. I want to think about what light that sheds on the 20th century.

The Dreams of the Founders of Family Medicine

Marcus Welby MD on the phoneWhile they were mindful of and grateful for the powerful advances in medicine, they believed that social and economic conditions which influenced the life of a person and a community had a greater impact on a person’s life and health than did the power and might of all of medicine.

They believed that medicine was a profession that involved more than a technical set of skills and a high income. They accepted the responsibility of caring for the whole person; mind, body and soul.

Is a liberal arts education good preparation for being a doctor?

Dr. Joel AngLiterature, fine art, poetry, music serve to remind overworked clinicians that they are part of a timeless tradition of healing whole human beings, who present in all their magnificence and complexity. Also, that physicians themselves participate in the tradition of physicians as humanists. Perhaps that’s why a liberal arts education – in my opinion – makes an important contribution to the practice of medicine today.

The misuse of health statistics by politicians

Rudolph Giuliani prostate cancerComparing five-year survival rates for the US and England is fundamentally misleading. Prostate cancer is overdiagnosed in the US. Many men who receive a diagnosis do not have cancer or will never develop symptoms, let alone die from the disease. The estimate for the US is that 48% of men diagnosed with prostate cancer do not have a progressive form of the disease. In England, on the other hand, testing is performed after symptoms appear, so a diagnosis is much more significant and meaningful.

Why is it so hard to reduce US health care costs?

Why is it so hard to reduce US health care costsA modern version of the Hippocratic Oath, the Physician Charter, commits physicians to work toward “the wise and cost-effective management of limited clinical resources.” But there’s little physicians – or anyone else – can do to change the behavior of politicians, insurance companies, pharmaceutical companies, or other entrenched stakeholders. It would indeed be heartening to see a visionary, public-minded physician emerge as a leader of the medical profession in the fight to solve this important and extremely difficult dilemma.

Why are we so willing to undergo cosmetic surgery?

Miss Plastic Surgery finals ChinaMembers of traditional societies accepted being told when and how to reshape their bodies. Their decision was binary: either participate or leave the group. In contemporary society, each individual is responsible for choosing and effecting her own reshaping, thus demonstrating her fitness for membership within a given field. Hierarchical position depends on displaying attunement to the field …. including what kind of body counts as right. The right body demonstrates having made the right assessment of capital, and thus becomes a potent display of rights to participation and position.

They are fighting against the segregation that made them lepers, bearers of bad news. They are fighting to remain members of the human community.

Pascal Bruckner on doctors and patients

Doctor patient relationshipMedical science’s individual servants are crushed under the weight of its promises, becoming commonplace and losing their authority; they are simple service providers who can be sued – often justifiably, moreover – if they commit an error. While the medical researcher, the scientist, and some surgeons whose skill amounts to genuine artistic genius retain immense prestige, in many cases the doctor is now seen only as a repairman who gets the machine running again until the next breakdown.

Can pharmaceutical drugs benefit society?

Goethe quotation: Whatever you can do ...There’s more to the value of health care than clinical effectiveness for patients and cost-effectiveness for individuals and governments. As we imagine the future of heatlh care, a welcome addition would be to plan for wider benefits to society. At this point in time in the US, it’s hard to imagine overcoming the political difficulties involved in reaching an agreement on what would benefit society. But it’s worth anticipating the possibility of a better future – the future we would want for ourselves and our children.

What gets lost in the bureaucratization of medicine

Medical practice as an artThe bureaucratization of medicine with increasingly complex rules, codes, algorithms, prompts, bylaws, schedules, and administrative structure is leaving its mark, but medicine at its fundamental is still about suffering, healing, and comforting; it is about individuals; it is about relationships and trust; it is about stories.

Patient safety and corporate profits

Patient safety firstA corporate board, on the other hand — whether it governs a hospital, a pharmaceutical company or an insurance giant — is legally required to give priority to stock holders over patients. When it comes to matters of health – which is to say life, death, and disability – it seems obvious to me that corporate boards are the least desirable level at which decisions about patient safety should be made. Decisions like increasing product sales at the expense of patient safety.
