One likely reason many doctors initially have difficulty participating on a patient-centered health-care team is
1) doctors tend to dislike other people in the medical field
2) doctors do not have time to listen to other people's advice
3) many doctors see themselves as solely responsible for the patient's well-being
4) doctors' malpractice insurance prevents them from collaborating with others

The answer is obviously 3) Many doctors see themselves as solely responsible for the patient's well-being because usually there are doctors for each patient and its usually one doctor. Cant be 1) because u cant be a doctor if u cant get along with others, friends/family, or your own co-workers. Cant be 2) because doctors share advice with each other to help one another and also do deep research. Cant be 4) because insurance doesn't stop doctors from working them from working or collaborating with one another.
