CARE-IT Overall Architecture
Digital clinical infrastructure is not an isolated IT construct.
It is part of clinical care — with direct impact on diagnostics, therapy, documentation, risk, and responsibility structures.
The CARE-IT overall architecture therefore does not describe a technical layering model, but a structural governance architecture for digital care systems.
At its center stands clinical care as the objective and reference point.
All framework elements are aligned to bring clinical effectiveness, safety, stability, and continuous evolution into structural coherence.
Architectural Logic
The CARE-IT architecture is composed of interlinked layers.
These layers do not function sequentially, but as a coherent governance system.
Clinical care defines the objective.
Principles provide normative orientation.
Domains structure the organizational action spaces, or management areas.
The maturity model supports development across the framework.
Artifacts translate the framework into operational application.
KPIs enable strategic self-observation.
Structural Model
Clinical Care
Clinical care is the point of reference for the entire framework.
CARE-IT does not govern digital infrastructure for its own sake,
but in relation to its clinical contribution.
This includes:
- clinical effectiveness
- patient safety
- continuity of care
- operational reliability
- responsible change
All subsequent layers derive their relevance from this reference point.
Foundational Principles (P1–P8)
The principles define the normative foundation.
They determine according to which standards digital clinical infrastructure is:
- evaluated
- designed
- governed
- operated
- evolved
The principles provide orientation in situations
where rules or standards alone do not yield a clear decision.
They define the reference framework for all subsequent layers.

Domains (D1–D6)
The domains structure the essential organizational action spaces.
They translate the principles into governable responsibility areas
and provide the structural model for leadership, operation, and evolution.
Domains are not silos.
They are coordinated governance perspectives on the same clinical system landscape.

Maturity Model
The maturity model enables structured development.
It describes maturity not as a single level,
but as a profile across principles and domains.
It:
- allows heterogeneous starting points
- makes structural tensions visible
- supports prioritization
- enables conscious organizational development
CARE-IT is therefore not an audit or certification framework,
but an instrument of organizational development.

Artifacts
Artifacts represent the operational implementation layer.
They are concrete, clinically understandable working instruments
through which domains are applied in everyday governance and decision-making.
They support:
- investment decisions
- risk deliberations
- governance resolutions
- project-to-operation transitions
- documentation of clinical system constellations
- evaluation of innovation initiatives
Artifacts are not documentation obligations,
but structured thinking and leadership tools.

KPIs
KPIs provide strategic self-observation across the framework.
They do not replace judgment,
but help organizations monitor whether governance structures are effective, balanced, and sustainable over time.
They make visible:
- whether clinical objectives are being supported
- whether domains are being actively managed
- whether maturity is developing coherently
- whether artifacts are translating into measurable organizational effect
KPIs therefore help connect framework structure with organizational learning.
Interaction of the Layers
The layers interlock:
- Clinical care provides the objective.
- Principles provide direction.
- Domains structure responsibility.
- The maturity model provides developmental orientation.
- Artifacts enable practical application.
- KPIs support strategic self-observation.
Only through their interaction does a coherent governance system emerge.
CARE-IT pursues an overarching objective:
Digital clinical infrastructure should be governed
in a way that consistently integrates clinical reality, responsibility, information integrity, and technology.
Architectural Unit: The Clinical System Constellation
The central unit of analysis is not the individual system,
but the clinical system constellation.
Digital clinical infrastructure does not act through isolated components.
Its clinical impact emerges through structured interaction.
A clinical system constellation integrates:
- clinical workflow
- applications
- data
- integration mechanisms
- medical devices
These elements form a coherent operational unit
that directly supports clinical care.
Structural View
Architecture therefore does not merely describe components —
it defines governable relationships between them.
This perspective is essential because:
- risks arise at the interfaces
- responsibilities span across systems
- data integrity depends on integration
- clinical workflows cut across multiple technical components
CARE-IT shifts the focus:
from system-centric thinking
to constellation-centric governance
