Machine logic for health might be a very dangerous thing.. Humans have a thing called nuance .. I don't expect devices to develop this soon.
But humans are also prone for errors, e.g. just overlooking an important result from a blood test. I also think doctors won't be completely redundant for diagnosises, but I am convinced that in future, they will only be needed to confirm a diagnosis.
This issue is very acute in the whole world! And sometimes the words and actions of the doctor depends very much!
