Actionable Real World Evidence Network

A platform that helps hospitals generate, share and use treatment insights to achieve better patient care.

We help hospitals by giving insights into the daily practice using data analysis​, enabling them to benchmark their clinical practice against others, ​allowing clinicians to learn from others by getting a view outside their hospital walls​ and empowering hospitals to identify improvement potential in the treatments they offer.

A standardised,
fit-for-purpose platform

We offer a platform to connect supply and demand of drug-related research questions on our network.


We simplify data extraction and validation, so hospitals can focus on caring for patients.

Unlocking the value of real-world data

We enable the use of real-world data that reflects the actual population treated to pinpoint improvement potential and best practices.

Enabling meaningful collaboration

We enable regulatory parties, insurance companies, life science companies, hospitals, and clinicians to collaborate on real-world evidence projects to improve care.
