Computer-based medical records: The need for storing a single datum in multiple orientations
The Medical Record (TMR) is a comprehensive medical information system designed with a computer-based medical record as its centerpiece. Experience in meeting the functional requirements of the health-care worker whose main concern is providing an immediate service, while maintaining a longitudinal patient record of manipulable size, has identified situations in which it is necessary to store a single datum redundantly in multiple databases. Examples include laboratory data, medication administration data, physiological monitoring data, and interpreted data necessary for research queries. Four examples of situations in which redundant storage of a single datum in multiple databases is helpful are described.
