Case study

Carers at Canterbury Care Home accessing NCRS pilot

The organisation and service

Canterbury Care homes have been delivering person-centred care since 2005, and currently operate three individual care homes in England and Scotland. 

Each resident receives bespoke support to become as independent as possible and enjoy the next chapter of their lives to the full.

As part of wanting to improve the quality of the service they provide, carers at Canterbury Care Home wanted to remove the need to chase GPs and wait weeks for them to respond about a patient's medical history.

Moving to NHS CIS2 Authentication

Most Care Home staff had the Microsoft Authenticator app already installed on their personal phones. For those that didn't, they were able to easily download it from the Apple App store or Google Play store.

Care Home staff using business phones had the Microsoft Authenticator app installed for them by their local IT support.

The experience

With the introduction of accessing NCRS using NHS CIS2 Microsoft Authenticator they can now look up the information themselves, saving theirs and the GP's time and improving the level of care that they provide.

To not have to rely on a GP getting back, and to have 24/7 access to care records is incredibly useful.

Out to NHS CIS2 Authentication

Both end users and applications need to be allowed to send requests out to https://am.nhsidentity.spineservices.nhs.uk/.

This domain is on randomly allocated IP address and is subject to change. 

In from NHS CIS2 Authentication

Whenever the user's NHS CIS2 Authentication session is destroyed (e.g. on expiration), NHS CIS2 Authentication can send Back-Channel Logout requests to the application.

These requests come from a small number of fixed IP ranges.

The application, therefore, may require that its hosting network allows requests from NHS CIS2 Authentication to be routed through firewalls to the application.

If the application is installed within trust networks, it is recommended that these are isolated on web servers and not directly exposed on critical internal servers.


Google Authenticator

Google Authenticator also works with NHS CIS2 Authentication.

Having spoken with a number of trusts and health and care organisations, we understand that Google Authenticator is a well-used authenticator app. Google Authenticator did not work with NHS CIS2 Authentication from the start, but we've since made changes to enable it to work.

However, NHS CIS2 Authentication recommends users and trusts use Microsoft Authenticator instead of Google Authenticator, due to the additional security in place (specifically a biometrics check to open and use the app).
