Not every physician or healthcare provider is held to the same standard of care. For instance, in a Syracuse medical malpractice case, a doctor specializing in internal medicine is not necessarily expected to have the same knowledge or skill as one who works primarily in the field of physical therapy.
Thus, if a patient who is treated by both professionals is injured by an act of negligence, it is quite possible that a medical malpractice case will only reach trial as to one of the healthcare workers. It often comes down to a question of which specialist was responsible for the area of the body or the type of care that led to the harm about which the plaintiff complains.
Of course, there are some circumstances in which several different medical professionals could be potentially liable to a patient. Each case is unique and must be determined on its own particular facts.
