Mission and Vision

The Center for Clinical Epidemiology and Outcomes Research (CLEO) is a non-profit organization committed to advancing public health, clinical research, and preventive healthcare in Greece and internationally. CLEO’s mission is not only to improve the quality and safety of medical care by combining scientific research, education, and evidence-based interventions but also to foster innovation in the field of public health research.

Through its work in public health research, epidemiology, infection prevention, antimicrobial stewardship, and outcomes research, CLEO supports hospitals, healthcare professionals, and policymakers in adopting best practices that reduce infections, optimize antibiotic use, and enhance patient outcomes.

CLEO’s vision is a future where public health and prevention are integral parts of every healthcare decision — where hospitals operate with transparency, patients receive safe and effective care, and communities are empowered through knowledge and awareness. By linking research with real-world practice, CLEO strives to build a culture of continuous improvement, accountability, and health equity for all.
