Medical malpractice is professional negligence by act or omission by a health care provider in which the treatment provided falls below the accepted standard of practice in the medical community and causes injury or death to the patient, with most cases involving medical error. Claims of medical malpractice, when pursued in US courts, processed as civil torts. Sometimes an act of medical malpractice will also constitute a criminal act, as in the case of the death of Michael Jackson.
Medical professionals may obtain professional liability insurances to offset the costs of lawsuits based on medical malpractice. Further establishment of conditions of intention or malice may be applied where applicable.
