To me it seems essential that one should have a basic knowledge of all aspects of medicine and have a qualifying examination at the end of six years to assess their expertise to be called a doctor of medicine and Surgery, so if called in any situation could offer qualified expertise.
At that stage you probably haven't made up your mind as to what branch of medicine that you want to follow...surgery, medicine, obstetrics, general practice etc and in doing so then a particular pot graduate path needs to be traversed.
An eye surgeon needs to know the ophthalmic manifestations of no eye conditions e.g rheumatoid arthritis, metabolic disorders, diabetes etc and so on and so an for ALL specialties, medical and surgical. The principles and practice of surgery, medicine, dermatology.
If you had a heart attack on a flight, there might not be a Cardiologist aboard, but you might like to know a Dermatologist or an Obstetrician might help.....OR better still an ABer with or without Internet connection ;-).
No.....I cannot see need for change.
