Physicians, of course, can be expected to know what they would do in particular situations and share their opinion with the patient or surrogate, especially if asked. It should be obvious, however, that what the physician would want in the patient’s situation has little relevance for the patient, who can be expected to hold different values and confront different nonmedical facts. If a physician is asked, “Doctor, what would you do in my situation?” the responsible answer is to first make sure that the patient or surrogate realizes how the physician’s answer will be dependent on the physician’s factual circumstances and religious and philosophical world view, and how irrelevant that answer may be to the patient. A physician might well respond by saying, “Well, I am a member of the ___ Church, am an old man with no further family responsibilities, and no particular desire to continue living, so I would… If you have similar values, affiliations, and life circumstances, you might consider doing likewise.” What seems foolish is for physicians to recommend goals they themselves would pursue in the patient’s medical condition. Even if physicians tried to replace their own life circumstances with the patient’s before recommending a goal of treatment, the result would be, at best, a vicarious conjecture on the physician’s part.
