Generic description of each maturity level in the social and environmental determinants of health maturity model (SIMM).

Level	Description
Level 1: Absent	At this level, no data collection policies, methods, technology platforms, analytics capacity, and operational and strategic impact exist.
Level 2: Ad Hoc	Ad hoc, unstructured, chaotic, minimal, or no coordination.
Level 3: Emerging	It is characteristic at this level that some SEDoH processes are repeatable, possibly with consistent results. This level could be considered as an originating/developmental stage.
Level 4: Coordinated	This level is characterized by coordination and communication between the different groups. Leadership is typically supportive, but does not provide designated resources for support. Success is still mostly a function of a few individual groups’ passion for making SEDoH happen.
Level 5: Supported	At this level, institutional support services related to SEDoH are established with support by leadership. There is operational and technical support as well as formal support for the piloting and launch of new services.
Level 6: Integrated	SEDoH data are readily available across the institution and information decision-making.
Level 7: Transformative	At the top maturity level, organizations start to learn from the collected SEDoH data. They are fully leveraging SEDoH, designing and developing their own SEDoH solutions to meet their innovative needs. The organization is continuously reviewing and improving its capabilities.

SEDoH = the social and environmental determinants of health.
