Making the Connection between Standard Terminologies, Use Cases, and Mapping

Abstract

Clinical data captured at the point of care using a standard terminology can be efficiently and effectively used for a variety of administrative and secondary purposes such as reimbursement, vital and health statistics trending, and health policy decision making. Maps are created with a specific purpose in mind and refined for particular use cases. They should be understandable, reproducible and useful. Driven by a philosophy of ‘code once, use many times’, after clinical care is recorded in an electronic health record (EHR) using a standard terminology, mapping tables can be used to identify the related code(s) in legacy terminologies.
