The accelerated aging of global populations poses unprecedented challenges for healthcare systems. The reality of a
100-year lifespan brings with it a shifting burden of multimorbidity and increased healthcare and long-term care expenses. The rapid accumulation of patient health data, including diagnoses, medications, and clinical parameters stored in electronic health records (EHRs), clinical registries, and other observational healthcare databases, provides an opportunity to use data science and network science to improve patient outcomes. Network science is increasingly used in medical research to analyze complex relationships in health data, providing valuable insights into comorbidities, disease trajectories, and patient stratification.

The medical group of the Complexity Science Hub in Vienna has established itself at the forefront of network medicine
with a specific focus on disease trajectories and multimorbidity [1-4]. As many diseases share common risk factors,
multimorbidity is expected to become an even more pressing health issue in the context of aging populations.
This workshop aims to bring together leading scholars, clinicians, and researchers working on network-based approaches in healthcare, particularly in the context of disease trajectories and promoting healthy ageing.

By fostering collaboration, sharing recent advances, and discussing challenges in the field, we seek to drive innovation in network-based health research. Given the rising burden of multimorbidity and the increasing availability of rich health data, now is a critical time to refine and expand network approaches to improve patient care and healthcare system resilience.

Key Questions of the Workshop:
1) How can we build meaningful international collaborations using highly sensitive medical datasets from multiple
countries?
2) What are the technical, ethical, and legal challenges?
3) What are the most promising big questions we can address by integrating claims data from multiple countries?
4) What insights can we generate to support early interventions and improve healthy aging?

Participation in this workshop is by invitation only.
