In the United Kingdom, the majority of eczema and psoriasis cases are successfully managed by General Practitioners (GPs) within primary care. However, because these conditions can vary from mild irritation to life-threatening emergencies, there are specific clinical thresholds where a specialist referral becomes essential. Dermatologists provide advanced diagnostic tools and access to systemic or biological treatments that are not available in a GP surgery. Understanding when your condition requires this higher level of expertise ensures that you receive the right care at the right time, preventing long-term skin damage and improving your overall quality of life.

1. Emergency Referrals (Immediate/Same-Day)
Some complications of eczema and psoriasis are medical emergencies that require immediate assessment by a hospital-based dermatology team.
- Suspected Eczema Herpeticum: This is a severe viral infection (usually the cold sore virus) in skin already broken by eczema. It presents as rapidly spreading, painful clusters of “punched-out” blisters. If not treated quickly with antivirals, it can become life-threatening.
- Erythroderma: This occurs when more than 90% of the body surface is red, inflamed, and shedding. It can lead to severe dehydration, infection, and the inability to regulate body temperature.
- Generalised Pustular Psoriasis: A rare but severe flare of psoriasis where small pus-filled blisters (pustules) develop over large areas of the body, often accompanied by a high fever and feeling very unwell.
2. Urgent Referrals (Within 2 Weeks)
An urgent referral is requested by a GP when the condition is severe and not responding to standard treatments, but the patient is not currently in a life-threatening crisis.
- Severe Flare-ups: When a patient has a sudden, extensive flare of atopic eczema or psoriasis that has not improved after one week of “optimum” high-potency topical therapy.
- Non-Responding Infections: If eczema or psoriasis is infected with bacteria (weeping or crusting) and a course of oral antibiotics plus topical steroids has failed to clear the infection.
- Significant Impact on Life: When the condition is causing extreme distress, such as severe sleep loss or the inability to attend work or school.
3. Routine Referrals (Standard Pathway)
Most referrals to a dermatologist fall into the routine category. These are essential for long-term management and diagnostic clarity.
- Diagnostic Uncertainty: If a GP is unsure whether the rash is eczema, psoriasis, or a “lookalike” condition such as a fungal infection or a rare type of skin cancer.
- Failure of First-Line Treatment: In the UK, if your skin condition is not well-controlled after trying appropriate strengths of emollients and topical steroids for a set period, a specialist should review your treatment plan.
- Suspected Contact Allergy: If a GP suspects that your eczema is being triggered by an allergy to a specific chemical or substance (such as a component in your laundry detergent or makeup), they will refer you for patch testing.
- Request for Advanced Therapy: If you are a candidate for phototherapy (UV light treatment) or need to start systemic medications like methotrexate, a consultant dermatologist must initiate and monitor these treatments.
4. Referrals for Special Populations
The threshold for referral is often lower for specific groups of patients where the condition is more complex to manage.
- Children under 12: NICE guidance states that children with uncontrolled eczema, recurrent infections, or growth failure related to their condition should be referred to a paediatric dermatologist.
- Sensitive Areas: Psoriasis or eczema affecting the face, genitals, or eyelids often requires specialist input because potent steroids cannot be used safely in these thin-skinned areas.
- Hand Eczema: If the condition is significantly affecting a patient’s occupation (e.g., a healthcare worker or chef who must wash their hands frequently), a specialist can offer tailored advice and treatments.
5. Identifying Systemic Complications
Sometimes the need for a referral is not about the skin itself, but about the complications associated with the disease.
- Psoriatic Arthritis: Up to one in three people with psoriasis will develop joint inflammation. If you experience persistent morning stiffness or joint pain, your dermatologist may work alongside a rheumatologist to manage your care.
- Mental Health Impact: If the visible nature of the skin condition is leading to severe social anxiety or depression, a dermatologist can provide access to psychodermatology services or advocate for more aggressive treatment to clear the skin.
Conclusion
A referral to a dermatologist is an essential bridge between standard primary care and the advanced therapies needed for complex or severe skin disease. Whether it is a life-threatening emergency like erythroderma or the simple need for diagnostic clarity, your GP uses clear clinical criteria to determine when specialist input is required. By understanding these thresholds, you can act as an advocate for your own health, ensuring that your eczema or psoriasis is managed with the most effective and safe treatments available in the UK.
What counts as a dermatology emergency?
Eczema herpeticum, erythroderma, and generalised pustular psoriasis are emergencies. Seek same-day medical care if you have these.
When is a referral considered urgent?
If severe flares or infections do not improve after one week of high-potency topical treatment, or if the condition causes extreme sleep loss.
Why might I need a routine referral?
For diagnostic clarity, failure of first-line treatments, access to phototherapy or systemic medicines, and professional allergy patch testing.
Do children have a lower referral threshold?
Yes. Specialist review is prioritised for children with uncontrolled eczema, frequent infections, or when high-potency treatments are required long-term.
Can mental health impact my referral?
Yes. Significant psychological distress, such as severe anxiety or depression linked to your skin condition, is a valid reason for specialist support.
Should I report joint pain?
Yes. If you have psoriasis and develop joint pain or morning stiffness, your GP should investigate for psoriatic arthritis.
