The physician's assistant is a position that was created in order to fill the need for lower cost medical care where direct consultation with an actual physician is not required but it does not seem to have really taken off in the US as far as I can tell. One thing that does seem to have an effect in lowering medical costs long term is technology such as the Da Vinci robot which allows "regular" doctors to perform procedures that previously could only be done by highly skilled surgeons.
