Improper, unskilled, or negligent treatment of a patient by a physician, dentist, nurse, pharmacist, or other health care professional. Negligence is the predominant theory of liability concerning allegations of medical malpractice, making this type of litigation part of Tort Law. Since the 1970s, medical malpractice has been a controversial social issue. Physicians have complained about a large number of malpractice suits and have urged legal reforms to curb large damage awards, whereas tort attorneys have argued that negligence suits are an effective way of compensating victims of negligence and of policing the medical profession Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review. Review journals are the evaluation of work by one or more people with similar competences as the producers of the work (peers). It functions as a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are used to maintain quality standards, improve performance, and provide credibility.
