The pediatric neurologist as expert witness with particular reference to perinatal asphyxia

The frequency of litigation related to alleged medical malpractice is increasing in Canada. For the neurologist, involvement in such litigation most often takes place in the context of acting as an expert witness and, for the pediatric neurologist, the most common clinical situation for which expertise is requested is that of possible perinatal asphyxia. The medical expert's primary role is to provide necessary guidance and assistance to the court, which may permit the rendering of decisions that are scientifically valid. This article will review the attributes of the medical expert witness. Aspects of perinatal asphyxia cases under litigation that commonly require the assistance of pediatric neurology expertise such as etiology, timing, extent of disability and life expectancy will also be reviewed in detail. The aim is to provide for the neurologist a clearer understanding of the responsibilities inherent in this increasing professional role.
