Use of the Children's Orientation and Amnesia Test at hospital discharge for children with neurological and non-neurological traumatic injuries

Abstract

The measurement of post-traumatic amnesia in children is a common clinical index of the extent of brain injury. The only published paediatric test, the Children's Orientation and Amnesia Test (COAT), has been standardized on a sample of children in a school setting who had not been injured or hospitalized. Two questions arise in the use of this test: are the published norms valid for hospitalized children with non-neurological trauma? and does the COAT offer better discriminative power or clinical utility over the adult test, the Galveston Orientation and Amnesia Test (GOAT)? This paper describes scores on the COAT for 28 children hospitalized with non-neurological injuries and compares them with the published scores. The hospitalized children scored within normal limits when compared with the school sample. In addition, 23 children with neurological traumatic injuries were given both the COAT and the GOAT. Failure rate was higher for the COAT. Some implications for the use of the COAT in paediatric trauma are discussed.
