This actually happens often, especially at Kaiser here in California. They always tell people it's their diet or their mind at intake. I know numerous people who have loved ones who have died as a result of that leading to a late or no diagnosis. The doctors are then insulated from malpractice because their pedagogy followed their "best practices" guidelines — they have experts testify that by flowing the guidelines, the doctor acted within the "professional standard of care." Then the doctors all rub their hands and go home.
