SNOMED International has designed this maturity model that allows users to assess the current status of implementation and facilitates planning for achieving greater levels of benefits from SNOMED CT.
Maturity Levels | |||||||||
| Level 0: PLANS TO USE SNOMED CT SNOMED CT is not yet used, but there are plans to do so. Currently, 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, through 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 applying simple ECL filters. | ||||||||
| Level 5: ADVANCED USE SNOMED CT is directly recorded in the clinical records. It's used as an ontology using post-coordination or creating new concepts in an extension. |
