The validation for usability of Emergency Coma Scale

Abstract

Purpose: We evaluated the utility of The Emergency Coma Scale (ECS) which was developed by ECS society in 2003. Method: We planned a multi-center study and tested the agreement and the accuracy of the ECS scoring, from two different aspects, among multiple raters. In regard to a former study, Medical staffs in each ER evaluated the consciousness level of patients by ECS, The Glasgow Coma Scale (GCS) and The Japan Coma Scale (JCS). Then, we compared the weighted agreements among multiple raters by calculating the Kappa coefficient and relationship between scoring and outcome of the patients.Result: We could observe significantly highest agreements at the ECS scoring among cerebrovascular disease including intracerebral hemorrhage and traumatic brain injury. While, the ECS scoring on admission showed stronger relation with outcome of the patients compared with the JCS and GCS. Discussion: We thought the briefness and accuracy of the ECS may bring the benefit for the evaluation of neurological emergency settings.
