You know, I asked that question innocently enough and then this popped up on Google.

Do doctors still carry medical bags? In the interests of good clinical practice, it is expected that most GPs will carry a doctor's bag stocked with equipment and drugs for medical situations outside the surgery (on home visits, for example). Perhaps surprisingly, though, there are no specific regulations as to the items the bag should contain.

So, aside from a stethoscope, and bottle of aspirin, what should be in a doctor's medical bag?
