This has been a pretty controversial article, because the evidence supporting the author's claims is not terribly good. One of his key studies relied on people who volunteered, while in med school, to participate in a study that would continue as they aged and died. It's not hard to imagine this group was more comfortable thinking about mortality than most doctors. Certainly more doctors than members of the general public have things like living wills that simplify end of life care than the average person, however more people who make as much money and have as much education as doctors also have living wills more often than the general public. I haven't been able to find numbers for doctors compared to, say, lawyers or professors. There does seem to be a subculture among doctors who are looking into how to die well, and may be better at it and act on their beliefs with greater confidence and urgency than those who don't encounter death as often, but it seems like many, if not most, doctors cling to life and try to delay the inevitable like the rest of us.
