In recent years, more and more states have recognized claims for negligent credentialing. Judgments and settlements in these cases can be huge, and the inclusion of a claim for negligent credentialing can put the health care provider at a tactical disadvantage. This presentation provides an overview of the states that recognize negligent credentialing claims, those that do not, and those that are likely to recognize such claims in the future. The common elements of such claims are explored, as are potential defenses. Real world examples from reported court decisions will be presented, and suggested best practices will be provided.
