I first encountered the 10 New Therapeutic Commandments when I started working with James McCormack on a lecture for medical students at the University of British Columbia.
Evolving from the chapter ‘The new therapeutics. Ten commandments’ by John S Yudkin in The Good GP Training Guide, they've developed into something completely wonderful.
I expect these capture the practice philosophy of most people who are interested in "Less is More" and "Choosing Wisely," and looking at them now, I think perhaps we should have devoted the entire lecture to this one slide.
See for yourself, the list and explanations, in the British Journal of General Practice.
My top 3 from the 10
1. Thou shalt have no aim except to help patients, according to the goals they wish to achieve
I think this could be the modern version of the most eminent aspect of the Hippocratic oath; not doing harm becomes respecting patient goals above all else)
2. Thou shalt always seek knowledge of the benefits, harms, and costs of treatment, and share this knowledge at all times
It is impossible to have an informed discussion and consent if one isn't informed.
7. Honour thy older patients, for although they often have the highest risk, they may also have the highest risk of harm from treatment
. . .
Look at the list to see the rest!
