The DIPSOC Study

Developing diagnostic criteria for psoriasis in children

Psoriasis (pronounced sor-aye-asis) can cause skin changes anywhere on the body. For many people it can be a long-term condition and have a significant impact on their quality of life.

Psoriasis can be associated with other diseases such as arthritis, which causes swelling and damage to the joints. It is therefore important that psoriasis is diagnosed early and accurately. This will help people receive specialist psoriasis treatment quickly.

Psoriasis in children and young people (17 years or younger) can be harder for non-specialist doctors and nurses to recognise. The development of diagnostic criteria will help health professionals recognise psoriasis. Diagnostic criteria will also support future research to improve the health of children and young people with psoriasis. 

Study Results

This video shows a presentation delivered at the British Association of Dermatologists Annual Meeting by Esther Burden-Teh. It was awarded Best Registrar's Paper.

This is an animation of the DIPSOC study results. It is 2-3 minutes long and suitable for children and adults.




DIPSOC results paper

In the DIPSOC study, the eDelphi diagnostic criteria were tested and refined to create a shorter list that best predict psoriasis in children and young people. The DIPSOC study ran from 2017-2019 and recruited 330 children from 12 paediatric dermatology departments in England, Wales and Scotland.

eDelphi paper

In this eDelphi consensus study, experts in psoriasis from 19 countries came together online to vote and agree on a list of a diagnostic of criteria for psoriasis in children and young people.

Diagnostic criteria systematic review

The systemic review searched the medical literature to check whether there were any existing diagnostic criteria for psoriasis in children or adults.
