Good checklists, on the other hand are precise. They are efficient, to the point, and easy to use even in the most difficult situations. They do not try to spell out everything--a checklist cannot fly a plane. Instead, they provide reminders of only the most critical and important steps--the ones that even the highly skilled professional using them could miss. Good checklists are, above all, practical.

The striking thing is that WHO doesn't really have the authority to do any of this. It can't tell governments what to do. It hires no vaccinators, distributes no vaccine. It is a small Geneva bureaucracy run by several hundred international delegates whose annual votes tell the organization what to do but not how to do it.…The only substantial resource that WHO has cultivated is information and expertise.

After readinf some essay on the nature of human fallibility, I was very aware that we are the recipients of a huge amount of discovery over the last century. Medicine exemplifies this. And that has transitioned us from a world in which people's lives were mostly governed by ignorance to one that's constrained by ineptitude. A century ago, we didn't know, for instance, what diseases afflicted us, what their nature really was, or what to do about them. And that has changed.

I think the extreme complexity of medicine has become more than an individual clinician can handle. But not more than teams of clinicians can handle.

My own son has a congenital heart condition, where his life was saved by a cardiac surgeon stepping in at 11 days of life to save his life. But he is now 21 years old because of constant monitoring and working with him with a primary care physician. that's the only reason now that he's getting to live a long and healthy life. That's what we're not rewarding. They don't have the kind of resources and commitment that we are giving to people like me. I have millions of dollars of equipment available to me when I go to work every day in an operating room.

I chose surgery because I thought that perhaps this would make me more like the kind of person I wanted to be.

We recruit for attitude and train for skill.
