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.

WITH BEST-IN-CLASS
DATA ANALYSIS SUPPORT

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
