Patient advocates are good idea even with domestic medicine. With reports of 100,000 deaths per year due to medical mistakes in the US alone, there is little doubt that an experienced patient advocate would be helpful. However, traveling for a medical procedure, whether it is to another location in the patient's home country or foreign country does add some additional challenges. Having someone who knows the places and people involved can be very useful. It is really a plus when the advocate has experience with the patient's medical procedure. Experience matters.
