title: Principles-based medical informatics for success--how Hong Kong built one of the world's largest integrated longitudinal electronic patient records.
abstract: Since 1994, the Hospital Authority has been developing and deploying clinical applications at its constituent 41 hospitals and 121 clinics. The Clinical Management System (CMS) is now used by over 4000 doctors and 20000 other clinicians on a daily basis to order, document and review care. The territory-wide Electronic Patient Record (ePR) has given clinicians an integrated, longitudinal, lifelong view of a patient's record. Today the CMS and ePR form an essential clinical and management tool to the Hospital Authority. The CMS handles two million clinical transactions per day, and the ePR has over 6TB of data covering 57 million episodes for 7.9 million patients. This paper describes how the HA has taken a principles-based approach to Medical Informatics to achieve its success in the enterprise-wide deployment and deep utilization of a comprehensive clinical information system.
