Mission

A research layer between routine data and decisions at the bedside.

Routine Data Enhanced Analytics for Clinical Trajectories via FHIR-native interoperable Decision Support Systems in the ICU

REACT brings measurements and clinical notes together to help intensive-care teams understand how a patient's condition changes over time. The goal is explainable support within existing workflows, ultimately in real time. Clinical judgement and responsibility remain with the treating clinicians.

FHIR-native by design

Profiles, terminology mappings and reusable resources make ICU analytics transferable between systems.

Governed from source to output

Lineage, access control and quality checks keep every transformation inspectable and accountable.

Built around clinical work

The research outputs are shaped with intensive-care teams, not detached from the decisions they support.

ICU / CONTINUOUS CONTEXT

continuous

A living clinical trajectory.

Critical illness unfolds over time. REACT keeps the changing relationship between observations, interventions and clinical decisions visible.

Research foundation

A common language for intensive-care trajectories.

Measurements and unstructured clinical notes are distributed across many ICU systems. REACT connects them using FHIR (Fast Healthcare Interoperability Resources), an international standard for exchanging health data, while preserving their source, timing and clinical meaning.

Research programme

A staged route from data foundation to clinical translation.

REACT connects a shared data infrastructure with dashboards for antibiotic therapy and circulatory instability. Around 200,000 ICU stays provide the basis for development and retrospective evaluation before planned clinical testing.

Workstreams / SP1–SP4

Four coordinated research contributions.

Data engineering, trustworthy infrastructure and clinically anchored decision support are developed as one connected research programme.

SP1

Routine-data integration & clinical dashboards

Event-driven ingestion of structured and unstructured ICU data, extraction into provenance-rich FHIR resources, and the development of interoperable web dashboards with clinician-facing CDSS components for reviewing trajectories and supporting decisions.

SP2

Trustworthy infrastructure

FHIR-native data management, conformance checks, policy-as-code, lineage and secure system engineering.

Principal investigatorDr.-Ing. Elias Grünewald

SP3

Antimicrobial stewardship

Developing an explainable dashboard to assess antibiotic guideline adherence and support de-escalation and therapy adjustment, using computable ICU concepts and patient context.

Principal investigatorDr. med. Mirja Mittermaier

InstitutionCharité / Infectious Diseases, Respiratory Medicine and Critical Care

SP4

Hemodynamic trajectories

Developing temporal models and an explainable dashboard to highlight early warning signs of circulatory instability and show the signals behind each risk assessment.

Research leadership / PIs

Principal investigators connect infrastructure research to clinical validation.

Four investigators from medical informatics and clinical medicine lead the work at Charité and University Medicine Essen. Together, they connect data infrastructure, clinical questions and evaluation with treating teams.
