Medical Intervention as a Novus Actus Interveniens: Giving Meaning to the Concept of Gross Clinical Negligence.

The focus of this article is the notion that only grossly negligent conduct by a health care provider will constitute a novus actus interveniens and break the chain of causation between a tortious act and the ultimate harm suffered by a plaintiff. More precisely, it explores the question of what it means for a health care provider to be grossly negligent. Its purpose is not to devise an exhaustive list of acts or omissions likely to constitute grossly negligent medical treatment; it is not necessary or even prudent to do so. However, it is argued that more clearly defined parameters are needed to distinguish ordinary, actionable negligence from gross negligence in a clinical context.
