Doctors, nurses, physician assistants and other medical professionals have an extremely high duty of care to their patients. That means they are legally obligated to competently provide an appropriate level of care for your illness or injury. That simple concept is a broad umbrella that covers everything from providing a correct diagnosis to prescribing appropriate medications to properly running tests or performing surgeries.
The bar for “appropriate level of care” essentially means the level of care a normal, competent doctor would provide. If a medical professional fails to provide the appropriate level of care, they could potentially be liable for the adverse medical outcomes that result.
However, patients can still die even when a doctor provides an appropriate level of care, which sometimes complicates medical malpractice claims or results in case dismissal.
