Patients are often not sent to the doctors who might be the best for that patient. There are many reasons for that. 1. Administrators don't know or don't care how to match patients with physicians precisely. 2. Administrators or insurance company will send you to any doctor within a broadly relevant specialty who "accepts new patients". This is done to even the workload of physicians. 3. A perfect expert may be too busy. He or she will never learn that there is a new patient who has a medical issue tailor-made for that expert. 4. You may insist and get [especially if you are a "VIP"] to see a "Head of the Department" or the most famous doctor in a hospital. But they might not have the best expertise for your subtype of disease. It's possible their skills might be "rusty" due to advancing age or high administrative burden of work. They could be "research submarines" who "surface" for clinical duties only for one or two months every year (and you will never know that).
