Introduction
Background
The SNOMED CT Implementation Maturity Framework (IMF) is a structured model developed by SNOMED International to support the effective adoption, integration, and optimization of SNOMED CT within healthcare systems.
SNOMED CT is a comprehensive clinical terminology used globally to enable consistent representation of clinical information and support semantic interoperability across systems and organizations.
Implementing SNOMED CT is a complex, multi-dimensional process that extends beyond terminology access. It requires coordinated progress across governance, technical infrastructure, workforce capability, and real-world usage.
The IMF has been developed through ongoing collaboration and input from the SNOMED International Member Forum, ensuring that it reflects real-world implementation experience across a diverse range of countries and healthcare systems. This collaborative approach allows the framework to incorporate practical lessons learned, common challenges, and proven strategies from national and organizational implementations.
The framework also builds on established maturity model approaches, adopting a progressive, staged model of capability development. It draws on concepts from widely used frameworks such as:
Capability Maturity Model Integration (CMMI)
ISO/IEC 15504 (SPICE)
Healthcare maturity models such as those developed by HIMSS
These models share a common principle: organizations evolve through defined stages of maturity, with each level representing increased capability, consistency, and value realization.
By applying this approach to SNOMED CT implementation, the IMF provides a standardized and repeatable method for assessing maturity, identifying gaps, and guiding continuous improvement.
Objective
The objective of this guide is to:
Describe the structure and purpose of the SNOMED CT Implementation Maturity Framework
Define the maturity domains and levels used to assess SNOMED CT implementation
Provide detailed assessment criteria for different stakeholder groups (Members, User Organizations, and Vendors)
Support organizations in evaluating their current maturity and identifying improvement opportunities
Enable consistent and comparable implementation of SNOMED CT across healthcare ecosystems
Scope
This guide provides a structured framework for assessing and improving the maturity of SNOMED CT implementation across the healthcare ecosystem.
It applies to SNOMED CT implementation at multiple levels, including national, regional, organizational, and product contexts, and supports all key stakeholder groups:
Members (National Release Centers)
User Organizations (healthcare providers and service organizations)
Vendors / Software Products
The framework covers the full range of capabilities required for effective SNOMED CT implementation, including governance, adoption, interoperability, capability development, and data use.
It is intended to support:
Assessment of current maturity
Identification of gaps and improvement priorities
Development of implementation roadmaps
Monitoring of progress over time
The guide defines what capabilities should be in place at different levels of maturity, but does not prescribe how these should be implemented. This allows flexibility to accommodate different healthcare systems, organizational structures, and technical environments.
This guide does not provide detailed technical implementation guidance, terminology modeling rules, or system-specific design recommendations. Instead, it focuses on enabling a consistent, comparable, and practical approach to understanding and advancing SNOMED CT implementation maturity.
Audience
This guide is intended for:
National Release Centers and health authorities
Healthcare organizations and providers implementing SNOMED CT
Health IT vendors and system developers
Digital health strategists and policymakers
Terminology, interoperability, and data standards specialists
Review
This guide is subject to ongoing review. Feedback from the international community is encouraged to support continuous improvement of the SNOMED CT Implementation Maturity Framework and its practical application.
