Modern medicine generates increasing volumes of valuable data, most of which is never used, and much of which is never saved. CNS is focused on capturing and aggregating this information to power improvements in patient care, organizational efficiency, medical diagnostics, and medical device design.

Our core principles

Innovative high-end design, led by medical professionals

Single entry, multiple use

Our systems are built around a guiding principle that data should only have to be entered once. Clinical data, audit data, research data and administrative data should all derive from the same entries through intelligent design, and data parsing which occurs out of sight of the user. By following this principle, we ensure data accuracy, granularity and timeliness.



Data stored on a single machine delivers limited benefits. We are expert in building systems which enable clinicians to access data wherever they need it. Typically our software is integrated with other hospital electronic medical records in such a way that it can be shared within hospitals, and also between hospitals if required.
