Patients' gender and age may also influence the care they get. I don't really agree. I think in traditional fee for service practice, there were also many doctors that overbooked. In the old days, the doctors wanted to increase their own income. Now it goes to the insurance company, but in either case it's wrong.
Patients deserve adequate time to have their concerns addressed.
However, good communication from the patient as well as the doctor saves time. That is the patients' responsibility. If the patient does not understand med-speak, the patient should ask what the doctor means. Many patients don't ask because they feel stupid. They should ask because there may be errors or misdiagonis.
