SNOMED CT is Australia’s national clinical terminology standard and one of the foundations of modern digital healthcare. It gives healthcare professionals and software systems a consistent way to record, share and interpret clinical information. As a result, it helps improve patient safety, interoperability and the quality of healthcare data across the Australian health system.
What Is SNOMED CT?
SNOMED CT (Systematized Nomenclature of Medicine Clinical Terms) is a comprehensive clinical terminology that describes medical concepts in a consistent and structured way.
Instead of relying solely on free-text notes, healthcare providers can use SNOMED CT to record diagnoses, symptoms, procedures, allergies, body structures, findings and many other aspects of patient care using standardised clinical concepts.
Each concept has a unique identifier. Computers recognise that identifier even when clinicians use different words to describe the same condition. As a result, healthcare systems can exchange and interpret clinical information more accurately.
Did you know? Australia uses SNOMED CT-AU, an Australian extension of the international SNOMED CT terminology. The Australian Digital Health Agency maintains and updates it to reflect Australian clinical practice.
Why Is SNOMED CT Important?
Every day, healthcare providers share information between general practices, specialists, hospitals, pathology providers, imaging services and government health systems.
However, if every organisation recorded clinical information differently, software systems would struggle to exchange and interpret patient data accurately.
As a result, SNOMED CT provides a common clinical language that improves consistency and supports:
- More accurate clinical documentation
- Improved communication between healthcare providers
- Safer clinical decision making
- Greater interoperability between healthcare systems
- Higher quality reporting, analytics and research
- Australia’s national digital health initiatives
A Simple Example
For example, imagine three doctors record the same diagnosis in different ways:
- Heart attack
- Myocardial infarction
- MI
Although these terms describe the same condition, computers may not automatically recognise them as identical if clinicians enter them as free text.
With SNOMED CT, each term links to the same underlying clinical concept. Therefore, healthcare systems understand that all three terms represent the same diagnosis.
How Is SNOMED CT Used?
Healthcare organisations use SNOMED CT in many different ways depending on their software and clinical workflows. Common uses include:
- Recording diagnoses and clinical findings
- Capturing symptoms
- Recording procedures and treatments
- Managing allergy information
- Clinical documentation
- Electronic referrals
- Clinical decision support
- Healthcare reporting and analytics
Many healthcare software systems use SNOMED CT behind the scenes to support clinical terminology. However, each system implements SNOMED CT differently depending on its features and integrations.
SNOMED CT in Australian Healthcare
Australia has adopted SNOMED CT as its national clinical terminology standard. Today, it plays an important role in many digital health initiatives.
The Australian Digital Health Agency maintains the Australian edition, known as SNOMED CT-AU. It also updates the terminology to reflect Australian clinical practice and national digital health standards.
Consequently, healthcare providers can exchange information more consistently while supporting safer and more connected patient care.
National standard: SNOMED CT-AU helps healthcare software speak the same clinical language across Australia’s digital health ecosystem.
How Zedmed Uses SNOMED CT
Zedmed supports SNOMED CT in specific clinical workflows where Australian healthcare standards require structured clinical terminology.
- Non-medicinal allergies: Zedmed uses SNOMED CT terminology to record non-medicinal allergens, such as egg white, bee stings and shellfish.
- Allergy reactions: Zedmed also uses SNOMED CT to record the type of reaction or symptoms associated with non-medicinal allergies, helping practices maintain consistent allergy records.
- My Health Record integration: When allergy information is shared with Australia’s My Health Record system, Zedmed sends the relevant allergy information using SNOMED CT terminology where required.
Other areas of Zedmed use different clinical coding systems where appropriate. For example, medicinal allergies use MIMS coding, while clinical problems are recorded using other terminology standards.
Supporting Australian standards: By supporting SNOMED CT for allergy-related information, Zedmed helps practices exchange important allergy data with My Health Record using nationally recognised clinical terminology.
SNOMED CT and Interoperability
Furthermore, one of the biggest advantages of SNOMED CT is interoperability. It allows different healthcare systems to exchange and understand patient information more effectively.
When healthcare providers record information using recognised terminology standards, they can share it more easily. They can also exchange accurate information between practices, hospitals, specialists and national digital health services.
Ultimately, this reduces ambiguity, supports continuity of care and helps clinicians access reliable patient information when they need it.
Understanding SNOMED CT
SNOMED CT is much more than a collection of clinical codes. Instead, it provides the common language that helps healthcare systems consistently record, interpret and exchange clinical information.
Understanding SNOMED CT helps healthcare providers appreciate how standardised clinical terminology supports safer information sharing and interoperability across Australia’s digital health ecosystem. Different software systems may implement SNOMED CT in different ways depending on their functionality.
