What is the standard of care for a physician?

It depends upon particular state law and the type of physician at issue. For example, a neurosurgeon is held to the standard of care of a reasonable neurosurgeon, not a general surgeon. This means that specialists are often held to more rigorous standards of care than generalists. The other difference between different state laws is that some states hold physicians to a national standard of care, while other state law holds physicians to a local standard of care.
