In a 2003 article, Joseph J. Gallo and others looked at what physicians want when it comes to end-of-life decisions. In a survey of 765 doctors, they found that 64% had created an advanced directive—specifying what steps should and should not be taken to save their lives should they become incapacitated. That compares to only about 20% for the general public. (As one might expect, older doctors are more likely than younger doctors to have made “arrangements,” as shown in a study by Paula Lester and others.)
Why such a large gap between the decisions of doctors and patients? The case of CPR is instructive. A study by Susan Diem and others of how CPR is portrayed on TV found that it was successful in 75% of the cases and that 67% of the TV patients went home. In reality, a 2010 study of more than 95,000 cases of CPR found that only 8% of patients survived for more than one month. Of these, only about 3% could lead a mostly normal life.
