The SNOMED CT Maturity Framework is a five level model that can be used to categorize implementations based on a scale of increasing SNOMED CT capabilities.
This framework can be used to assess the current maturity level of a SNOMED CT implementation, or to help plan for higher maturity levels which provide additional benefits.
SNOMED CT Maturity Framework | |
| Level 0: PLANS TO USE SNOMED CT SNOMED CT is not used yet, but there are plans to do so. Clinical information is stored as free text or using other code systems. |
| Level 1: MAPPING TO SNOMED CT SNOMED CT is not directly recorded in the clinical records. It's used indirectly, using a mapping mechanism. |
| Level 2: SIMPLE CODE SYSTEM SNOMED CT is directly recorded in the clinical records. It's used as a flat list of codes. |
| Level 3: HIERARCHY SNOMED CT is directly recorded in the clinical records. It's used as a hierarchy of codes to support various system functions. |
| Level 4: SEMANTIC NETWORK SNOMED CT is directly recorded in the clinical records. It's used as a semantic network of relationships with simple ECL queries. |
| Level 5: ADVANCED USE |
