International Standard Accident Number: A Master Case Index Linking Accident & Emergency with Medical Data.

Unconnected data silos make it difficult to view a patient's accident and emergency case in a comprehensive way, i.e. across all sectors. This includes the emergency medical services (EMS), medical data in a hospital's electronic health record (EHR) as well as event data recorders (EDRs) collecting information about the circumstances of the accident and emergency event. In this paper, we propose a conceptual architecture which introduces a novel case-based record linkage approach and the international standard accident number (ISAN) as a master case index for linking data from EDR, EMS, and EHR.
