To prove a medical malpractice case, we have to establish 3 key links in the case. First, we must prove that the doctor/nurse/healthcare provider was negligent, or below the standard of care. In other words, that he or she did something that was not reasonable or prudent. Second, we must prove that what the doctor/nurse/healthcare provider did wrong was a cause of the injuries. If the person was injured, but the defendant did not cause it, there is no case. Finally, we must prove what the person’s damages (injuries) are. All three of these elements must be met in order to proceed to court.
