Data is fed into DCM from other applications (eg: Audiology, Oncology, Pathology, Radiology)  via HL7 and detail can be viewed here.

HL7 (Health Level Seven) is a set of international standards used to transfer and share data between various healthcare providers. Specifically, HL7 bridges the gap between health IT applications, making the sharing of healthcare data more efficient compared to older methods. These standards define how information is packaged and communicated from one party to another, setting the language, structure, and data types required for seamless integration between systems. HL7 standards support clinical practice, the management, delivery, and evaluation of health services, and are recognized as the most commonly used in the world. The primary HL7 standards include:

1. Clinical Document Architecture (CDA®): Used for clinical documentation and exchange of patient summaries and reports.
2. Electronic Health Records (EHR): Provides functional models and profiles for managing electronic health records.
3. FHIR® (Fast Healthcare Interoperability Resources): A modern standard for exchanging healthcare data using RESTful APIs.
4. Version 2 (V2): A widely used messaging standard for healthcare systems.
5. Version 3 (V3): Based on HL7’s Reference Information Model (RIM), it includes a suite of specifications.
6. Arden Syntax: Represents procedural clinical knowledge for sharing computerized health knowledge bases.
7. CCOW (Clinical Context Management Specification): Facilitates application integration at the point of use.
8. Cross-paradigm/Domain Analysis Models: Logical level standards for various domains².

These standards play a crucial role in enabling interoperability and seamless communication within the healthcare ecosystem.
