Principles: How have we designed CAREFUL?

CAREFUL is built on four principles

  1. Confidentiality
  2. Security
  3. Ease-of-use
  4. Interoperability


No patient data should be visible to any user who is not authorised or who does not reasonably need to see that data.

To that end, CAREFUL ensures that patient data is restricted to members of teams that are looking after (responsible) for that patient.

We also ensure that data is hidden when the user is no longer using their machine and visibility of data is only restored when the user once again uses their password.


All our data is encrypted at rest and in transit. It is secured by Microsoft Azure and is protected through multiple levels of security access.


Our platform is “user-first”. It uses the very best standards of usability, ensuring the very best user experience.


Patient data does not exist alone. Interoperability of CAREFUL against any other legacy system is an important aspect of our design.
