Segmentation – Patient Needs Group (PNG)

Posted on:

You may notice a test result appear in your NHS APP referring to “segmentation” or “Johns Hopkins Adjusted Clinical Groups (ACG) system score”.
Segmentation/Johns Hopkins Adjusted Clinical Groups (ACG) system score is a simple way of categorising patients based on their specific health needs. It 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.

What is segmentation?
 
We use segmentation to group people based on shared characteristics, needs, or behaviours. This allows us to tailor care delivery and policies to better meet the specific needs of each group.
When we do this for all groups we get healthier people and a healthier population.
What are the Johns Hopkins Adjusted Clinical Groups?
In Buckinghamshire, Oxfordshire and Berkshire West Integrated Care Board (BOB ICB) we use a well tested set of 11 segments/groups based on research by Johns Hopkins University. These are in the image above. Factors used for grouping include the number of conditions a person has and how severe those conditions are. This helps us decide what level of support that patients might need.
The categories break down into:
  • Low need (PNG 1-4) (Green): Patients without significant health issues who need less intervention. Preventative care may stop them becoming unwell.
  • Moderate need (PNG 5-9) (Orange): Patients who have a condition that is, generally, well managed. These patients may need occasional support to remain stable.
  • High need (PNG 10-11) (Red): Patients who have several conditions. They may need regular monitoring or a more coordinated healthcare approach.
You may have seen this score in your NHS APP as “Johns Hopkins Adjusted Clinical Groups (ACG) system score” – see example (note the final implementation may be slightly different from that shown).

Klinik 

A reminder that all appointment requests are added via the online form for GP triage (Klinik) this enables us to assess urgency and direct you to the best clinician - Right Person Right Time.  This request can be made by yourself or a member of staff at the surgery if you cant do this for any reason.  You can log in using your NHS App log in but you dont need this you can proceed without a log in. 

If you are requesting repeat medication this is far better done via the NHS App (or if you still use Patient Access) as the list is there and you dont have to retype all the names.  The medication request then goes directly into the electronic system for signing. If you are asking for a one off medication or an item that isnt on repeat then please use the online form on the website (Klinik)

Thank you to all those who have embraced this system, we are no longer asking anyone to call back another day and all requests are clinically assessed as they come in which is far safer for our patients.
