Segmentation

You may notice a test result appear in your NHS app referring to Johns Hopkins adjusted clinical groups.

In order to help us tailor care according to individual patient need, we now have access to a tool that segments or categorises our patient population into Patient Need Groups (PNGs). This system of segmentation, called the ACG® System, was developed by Johns Hopkins University, which is renowned for its contributions to advancing medical practices and healthcare systems globally.

Segmentation helps us as a practice understand the individual needs of our patients based on their health and wellbeing to support personalised care and ensures you get the right support in a timely way.
