Are people with psoriasis automatically checked for arthritis? 

For individuals living with skin psoriasis, the risk of developing psoriatic arthritis (PsA) is a significant clinical consideration. While psoriasis is primarily a skin condition, it is a systemic inflammatory disease that can eventually involve the joints in up to one-third of cases. In the UK, healthcare guidelines emphasize the importance of regular monitoring to catch the transition from skin disease to joint disease as early as possible. However, the “automatic” nature of these checks depends largely on the setting of your care and the awareness of your clinical team. 

What We’ll Discuss in This Article 

• UK clinical guidelines for screening psoriasis patients for arthritis 

• The role of the PEST (Psoriasis Epidemiology Screening Tool) questionnaire 

• How often your GP or dermatologist should check your joints 

• Key symptoms that trigger a formal rheumatology referral 

• Why “silent” joint inflammation requires proactive monitoring 

• Your rights as a patient to request an annual arthritis review 

In the UK, people with psoriasis should be checked for psoriatic arthritis at least once a year as part of their routine clinical review. While this process is mandated by national clinical standards, it is not always a literal “automatic” blood test; instead, it usually involves a series of screening questions and a physical review of your joints and nails. The NHS notes that if you have psoriasis, you should be screened for psoriatic arthritis annually to ensure that any joint inflammation is caught before it causes permanent damage. 

National Screening Standards (NICE Guidance) 

The National Institute for Health and Care Excellence (NICE) provides clear instructions to GPs and dermatologists regarding the care of people with psoriasis. These guidelines state that healthcare professionals must offer an annual assessment for psoriatic arthritis to all patients with any type of psoriasis. 

The reason for this proactive approach is the “window of opportunity.” Because joint damage can begin long before a patient experiences severe pain, regular screening is the only way to ensure that treatment starts in time to prevent irreversible bone erosion. If you have not had a joint review in the last 12 months, you are encouraged to book a “psoriasis annual review” with your GP surgery. 

The PEST Screening Tool 

The most common way clinicians “automatically” check for arthritis is through a validated questionnaire called the PEST (Psoriasis Epidemiology Screening Tool). This is a simple set of five questions designed to identify the early warning signs of psoriatic arthritis. 

The questions typically ask if you have ever had: 

• A joint that has become swollen without an injury. 

• A doctor tell you that you have arthritis. 

• Fingernails or toenails with holes or pits. 

• Pain in your heels (enthesitis). 

• A finger or toe that was completely swollen like a sausage (dactylitis). 

If you score 3 or more on this tool, the NICE guidelines recommend an “automatic” and urgent referral to a rheumatologist for a more in-depth assessment. You can find more information on the diagnostic criteria and screening tools through the NICE clinical knowledge summaries. 

What Happens During a Joint Check? 

A proper screening involves more than just a questionnaire. During your annual review, your clinician should perform a brief physical examination, looking specifically for “hidden” signs of psoriatic disease that are linked to joint involvement. 

Screening Action	What the Clinician is Looking For
Joint Inspection	Swelling, warmth, or tenderness in small and large joints
Nail Review	Pitting, crumbling, or lifting of the nail plate
Tendon Check	Tenderness at the Achilles tendon or the soles of the feet
Dactylitis Check	Uniform swelling of an entire digit (sausage finger)
Spine Review	New or persistent stiffness in the lower back or neck

If these physical signs are present, a GP will often order baseline blood tests to check your inflammatory markers (CRP and ESR). However, it is important to remember that many people with psoriatic arthritis have normal blood tests, so a “clear” blood result does not automatically rule out the condition if physical symptoms are present. 

Conclusion 

While the UK healthcare system has established a framework for annual psoriatic arthritis screening, patients must often remain proactive in ensuring these checks occur. By understanding the role of the PEST tool and the importance of the annual review, you can play an active part in protecting your joint health. Early detection is the most powerful tool for preventing long-term disability. If you experience sudden, severe joint swelling, a high fever, or your skin begins to blister or peel extensively, call 999 immediately.
