No, Helen. Medical doctors are called Doctor, but surgeons are called Mister. Dates back to the days when surgery was a side-job for barbers but now has become a piece of oneupmanship. A surgeon would be quite miffed if somebody downgraded him by calling him Doctor.

I'm not sure of the exact details, but I think the nursing positions in a hospital used to be nurse, sister (in charge of the nurses in a ward) and matron (chief nurse for the whole hospital).
