Dr Bard-Parker's latest entry talks very succinctly about this new (& evolving) relationship. Check out this article from the Boston Globe penned by Dr Marcia Angell , lecturer from Harvard Medical School.
I am not sure if the doctor-patient relationship in Singapore has reached this level in general. I believe that it has to a certain point, especially among the better-educated & usually younger patients.
In any case, I agree with Dr Bard-Parker that this is great advice from Dr Angell :
"As patients, your best bet is to ask your doctors what they would do in your place, and persist until you get a straight answer. If nothing else, that forces doctors to imagine being in your shoes, at least for a moment, and it may cause them to think more deeply about what you should do."
