The Decision Tree book cover

The Decision Tree by Thomas Goetz is an excellent call-to-arms for personalized medicine and taking control of the options that you, as a patient, now have in our new era of healthcare. Goetz has an extraordinary ability (honed at Wired Magazine) to parse complicated scientific topics into clear and efficient prose.

He touches on many personal stories, some that have been heard before in medical non-fiction (like an Ashkenazi Jew being tested for BRCA1, the genetic mutation that often leads to breast cancer. An almost identical story is related, somewhat ironically, in one of Dr. Jerome Groopman’s early books, but more on him in a minute). Other stories are newer, and focus on some other possibilities of not only genetic testing but also of self-tracking and patient communities, and this is where the book really shines.

Goetz illuminates many of the technologies that are allowing modern patients track and control their health, such as Nike+, 23 and Me, PatientsLikeMe and many others. He also sheds new light on Weight Watchers and explains, by way of what we know now from other self-tracking programs (and other failed diet regimes), why the Weight Watchers model of “points” and group meetings has been so successful for so many.

The one thing that doesn’t quite stack up is the title of the book itself. It is my hunch that using the “decision tree” metaphor to explain the unique choices that we will all have to face as patients is an attempt to legitimize patient activism by translating it into a scientific and statistical model often used in evidence-based medicine (for an example of using decision trees in evidence-based clinical care, see here).

Integrating patient activism into the paradigms of modern medicine is difficult and requires the eloquence and dedication that Goetz provides in this book. Too often patients still meet the locked doors of the ivory tower. But Goetz does a good enough job explaining the different choices each of his examples faces, that the “decision trees” themselves do not add much to the book; if anything, they consistently struck me as over-simplified pictures of a situation just described in detail. It is vital to know and to learn the ins and the outs of your medical situation in order to assist your doctor in your treatment plan. But whether you jot notes in a book or mock-up your choices in SketchUp seems inconsequential.

It is also important that patients not forget the lynchpins of their care in the face of all these wonderful (but often distracting and sometimes frightening) technological tools: their doctors. I recently came across an excellent encapsulation of this book by @Doctor_V as compared to Dr. Jerome Groopman’s “How Doctors Think.” In it, he sets up the two books as opposite one another; the latter arguing for a golden-age of wisdom handed down by Harvard-trained “Masters of the Universe,” while the former seems to push self-tracking and patient activism so hard that there is hardly for a doctor in your care whatsoever. As a librarian, I’ll now be hard pressed to recommend either one without the other.

  1. Isn’t a decision tree simply another way of saying that patients have a whole range of choices open to them now in an era of personalized medicine?

    I also prefer to say ‘patient advocacy’ not activism. Not sure why exactly – perhaps the latter seems too militant.

    Thanks for the review Daniel
