Medical malpractice is a legal cause of action that occurs when a medical or health care professional, through a negligent act or omission, deviates from standards in their profession, thereby causing injury or death to a patient. The negligence might arise from errors in diagnosis, treatment, aftercare or health management.
An act of medical malpractice usually has three characteristics. Firstly, it must be proven that the treatment has not been consistent with the standard of care, which is the standard medical treatment accepted and recognized by the profession. Secondly, it must be proven that the patient has suffered some kind of injury due to the negligence. In other words, an injury without negligence or an act of negligence without causing any injury cannot be considered malpractice. Thirdly, it must be proven that the injury resulted in significant damages such as disability, unusual pain, suffering, hardship, loss of income or a significant burden of medical bills.
In common law jurisdictions, medical malpractice liability is normally based on the tort of negligence.
Although the law of medical malpractice differs significantly between nations, as a broad general rule liability follows when a health care practitioner does not show a fair, reasonable and competent degree of skill when providing medical care to a patient. If a practitioner holds himself out as a specialist a higher degree of skill is required. Jurisdictions have also been increasingly receptive to claims based on informed consent, raised by patients who allege that they were not adequately informed of the risks of medical procedures before agreeing to treatment.
As law varies by jurisdiction, the specific professionals who may be targeted by a medical malpractice action will vary depending upon where the action is filed. Among professionals that may be potentially liable under medical malpractice laws are:
Physicians, surgeons, psychiatrists and dentists.
Nurses, midwives, nurse practitioners, and physician assistants.
