Clinical Terminology

Clinical terminology (CT) is a structured vocabulary used in clinical practice to accurately describe the care and treatment of patients. It covers complex concepts such as diseases, operations, treatments and medicines. Healthcare providers around the world use specialised vocabulary to describe diseases, clinical procedures, findings, treatments and medicines. Clinical Terminology products aim to create a comprehensive, non-ambiguous national vocabulary for implementation software applications used within the Australian healthcare community.

For interoperable electronic health information, it must be able to record, read and interpret clinical information which is exchanged between systems (e.g. drug names, diagnoses, or pathology test results). A key task for the National Clinical Terminology and Information Service (NCTIS) is therefore to identify methods of supporting the implementation of clinical terminology and clinical information standards across the Australian healthcare community.
