Medical negligence is a term that describes a physician or other medical professional's omission or neglect which causes harm or injury to a patient. Negligence is slightly different from a purposeful act, because it typically describes a physician who forgets something, fails to take precautionary methods, fails to diagnose a disease based on symptoms and signs - and more. IN order to determine medical negligence, a judge and jury must determine whether a physician has treated the patient according to an established standard of care. In other words, they will try to determine whether this physician treated this patient with as much care as another physician would treat another patient. If it has been found that they have not, it may be considered medical negligence.
