How to Practice Medicine in a World We Can Never Truly Understand

Central to the problem of how best to live in a world that we cannot understand is how to regard:

“The Extended Disorder Family (or Cluster): (i) uncertainty, (ii) variability, (iii) imperfect, incomplete knowledge, (iv) chance, (v) chaos, (vi) volatility, (vii) disorder, (viii) entropy, (ix) time, (x) the unknown, (xi) randomness, (xii) turmoil, (xiii) stressor, (xiv) error, (xv) dispersion of outcomes, (xvi) unknowledge.” (Nassim Nicholas Taleb, Antifragile, London: Allen Lane, 2012)

To this impressive list, I would add seventeenth and eighteenth items:  failure and death. All of these characteristics scare and frighten most of us, and so we do our best to avoid them.

Despite the popularity of self-help books emphasizing the pursuit of happiness, a vocal minority has advocated embracing all of the above negative items in order to live fully and successfully.

Eric G. Wilson perhaps provides the best overview of this minority report when he observes that

“To desire only happiness in a world undoubtedly tragic is to become inauthentic, to settle for unrealistic abstractions that ignore concrete situations.”

And

“Our passion for felicity hints at an ominous hatred for all that grows and thrives and then dies.” (Eric G. Wilson, Against Happiness, New York:  Sarah Crichton Books, 2008)

To be alive and to realize that you are going to die means being insecure and vulnerable.  According to Martha Nussbaum one should embrace this uncertainty.

Through a Scanner Darkly: Three Health Care Trends for 2013

As we anticipate a new year characterized by unprecedented interest in healthcare innovation, pay particular attention to the following three emerging tensions in the space.

Tension 1: Preventive Health vs Excessive Medicalization

A core tenet of medicine is that it’s better to prevent a disease (or at least catch it early) than to treat it after it has firmly taken hold.   This is the rationale for both our interest in screening exams (such as mammography) as well as the focus on risk factor reduction (e.g. treating high blood pressure and high cholesterol to prevent heart attacks).

The problem, however, is that intervention itself carries a risk, which is sometimes well-characterized (e.g. in the case of a low-dose aspirin for some patients with a history of heart disease) but more often incompletely understood.

As both Eric Topol and Nassim Taleb have argued, there’s a powerful tendency to underestimate the risk associated with interventions.  Topol, for example, has highlighted the potential risk of using statins to treat patients who have never had heart disease (i.e. primary prevention), a danger he worries may exceed the “relatively small benefit that can be derived.”  (Other cardiologists disagree – see this piece by colleague Matt Herper).

In his new book Antifragile, Taleb focuses extensively on iatrogenics, arguing “we should not take risks with near-healthy people” though he adds “we should take a lot, a lot more, with those deemed in danger.”

Both Topol and Taleb are right that we tend to underestimate iatrogenicity in general, and often fail to factor in the small but real possibility of potential harm.

At the same time, I also worry about external experts deciding categorically what sort of risk is or isn’t “worth it” for an individual patient – a particular problem in oncology, where it now seems  fashionable to declare the possibility of a few more months of life a marginal or insignificant benefit.

Even less dramatically, a treatment benefit that some might view as trivial (for hemorrhoids, say) might be life-altering for others.  For these sufferers, a theoretical risk that some (like Taleb) find prohibitive might be worth the likelihood of symptom relief.  Ideally, this decision would ultimately belong to patients, not experts asserting to act on patients’ behalf.
