I agree with that. I agree that GPA may reflect work ethic, discipline, and many other personal characteristics that may stay with the person even later in life and affect patient care. But, I am sure that out of almost 30,000 MD/DO students there are enough of those too. I don't think there is a way to eliminate this for 100%.
About 200,000-250,000 people die every year due to medical errors. That is no.3 cause of death in the US.
There are about 2,000 surgeries performed on the wrong parts on the body every year as well.
Around 400 physicians commit suicide and thousands suffer from similar mental health issues and they still provide patient care.
It is not just podiatrists.
Though, I would prefer to set a cut-off at 3.0 GPA for ALL healthcare professions.
