RESUMO
The Hospital Authority developed the Information Architecture (IA) model in 2002 to support a fast, robust, flexible and accurate electronic patient record (ePR) to meet the high-tempo health care environment in Hong Kong. With several successful applications in sharing data that were created for the same patients in various systems, the IA model was further developed to extend the longitudinal ePR to include one's fetal data as entered in the mother's record. This paper describes how various IA elements: Section, View, Form, Group, Entity, Content, Document supports the building of a true womb-to-tomb ePR for the HA patients. The future focus of Information Architecture in the HA will include building a Information Architecture Management System and linking the ePR with other patient records in the community.
