The Association of British Clinical Diabetologists on The NHS Network

The Association of British Clinical Diabetologists (ABCD) is delighted to have achieved a presence within the NHS network. This page is not itself on NHS network, as we wish the information to be universally available, but these pages form ABCD’s portal into the NHS network.

What is the NHS Network and why a presence on it for ABCD?
The National Health Service (NHS) Network, is a secured network connecting all NHS locations, in particular linking acute hospitals, GP surgeries, NHS facilities and Care Sites. For ABCD the NHS network allows anonymised, encrypted patient data to be moved between approved locations, meeting Information Governance Standards currently in force, and allows secured servers within a hospital to host the data of NHS patients. It is therefore the most appropriate and secure way to communicate data from centres taking part in our nationwide audits to our servers for secure storage and analysis. Using the NHS network, centres joining the national audit effort will be able to access their own anonymised patient data on their local NHS computers as they do with their other local clinical systems, accessing, reviewing and auditing their own local data in order to learn from the local experience.

Why ABCD nationwide audits
At the same time the data, in anonymised form, will be joined to the nationwide audit where, by being combined with similar data from all over the UK, the rate at which we can learn about new medications in real clinical practice is increased – through the force of numbers. For example it can be seen from the slide, lower left, than we learned from the nationwide exenatide and liraglutide audits, that in real clinic practice patients treated with these medications in the UK had far worse glycaemic control and were much heavier than patients treated in clinical trials – thus reducing the extent to which information from the clinical trials can be extrapolated to real clinical life. ABCD hopes, through its audits, to gain insights into both safety and efficacy of new medications. ABCD hopes that the data collected will inform future practice and guidelines.
