Psoriasis is a chronic immunologic condition that affects the skin, leading to inflammation which presents as red, scaly patches. Approximately 1 million Canadians live with psoriasis, making it one of the most common chronic skin conditions in the country. While psoriasis affects individuals across all demographics, its presentation, diagnosis, and treatment vary significantly depending on skin tone. People of colour often face unique challenges in managing this condition due to differences in presentation and historical underrepresentation in clinical trials and medical education. This article explores the nuanced experiences of people of colour with psoriasis, and highlights the steps being taken to address these gaps.
Psoriasis and Its Unique Challenges in Skin of Colour
In people with lighter skin tones, psoriasis typically manifests as bright red plaques covered with silvery-white scales. However, in individuals with darker skin, the presentation can differ significantly. The plaques may appear violet, dark brown, or grey rather than red, which can make the condition less recognizable. This difference in appearance often delays diagnosis, as healthcare providers may overlook or misidentify clinical features. Post-inflammatory pigmentation change is another significant issue for people of colour. Sometimes when inflammation resolves, it leaves darkened or lightened patches on the skin. These challenges underscore the need for more education among healthcare providers and greater representation in clinical research to ensure that patients of colour receive timely and accurate diagnosis and disease-management.
Barriers to Diagnosis and Treatment for people of colour
Several systemic and cultural barriers contribute to the underdiagnosis and misdiagnosis of psoriasis in people of colour:
- Underrepresentation in Clinical Research: Clinical trials in psoriasis have historically included predominantly white participants. For example, only 14.2% of participants in phase III trials for plaque psoriasis were nonwhite. This lack of diversity in research means there is limited data on how psoriasis manifests and progresses in individuals with darker skin tones.
- Gaps in Medical Education: Dermatology resources often lack adequate representation of skin conditions on darker skin. Studies show that only 4-19% of images in dermatology textbooks feature conditions on darker skin tones. This contributes to a lack of familiarity among healthcare providers in diagnosing and treating psoriasis in people of colour.
- Cultural and Societal Factors: In many communities, skin conditions such as psoriasis are stigmatized, leading individuals to delay seeking medical attention. Additionally, there is often hesitancy to pursue treatments that are perceived as non-traditional, which may limit treatment options and adherence.
- Lack of Culturally Competent Care: A significant number of non-white patients report that their healthcare providers lack cultural competence. This can lead to feelings of mistrust and dissatisfaction, discouraging individuals from seeking or continuing treatment.
Insights from the Canadian Skin of Colour Consensus Forum
Recognizing these disparities, the Canadian Skin of Colour Consensus Forum was established to address the unique challenges faced by people of colour with psoriasis. The Forum brought together experts in psoriasis to discuss these issues and develop actionable solutions. The Forum identified several key priorities:
- Increasing the representation of people of colour in clinical trials to ensure more comprehensive research and understanding of psoriasis across diverse populations.
- Enhancing dermatology education by incorporating more inclusive reference materials and training to equip healthcare providers to diagnose and treat psoriasis in patients of colour effectively.
- Promoting culturally competent care to create a supportive and understanding environment for patients.
Key Recommendations and Next Steps
The Forum’s findings were distilled into 24 consensus statements designed to guide clinical practice and improve outcomes for patients of colour. These recommendations include:
- Expanding initiatives that aim to improve the management of moderate to severe plaque psoriasis in patients of colour.
- Integrating consensus findings into dermatology practices across Canada, ensuring healthcare providers are equipped to recognize and address the unique needs of patients of colour.
- Addressing cultural stigmas around psoriasis and working to reduce the barriers that discourage individuals from seeking care.
“As healthcare providers, it’s critical that we recognize the unique ways psoriasis presents in people of colour,” said Dr. Jensen Yeung, Dermatologist and Associate Professor at the Department of Medicine, University of Toronto. “By improving representation of patients of colour in research and equipping clinicians with better tools and training in diagnosing and managing psoriasis in individuals with darker skin tones, we can reduce diagnostic delays and ensure patients receive the care and management they require. The consensus paper is a step forward in addressing these disparities and creating a more equitable healthcare system.”
Building an Inclusive Future
The Canadian Skin of Colour Consensus Forum represent crucial steps toward equity in healthcare. By addressing the historical underrepresentation of people of colour in research, improving medical education, and promoting culturally competent care, these initiatives are paving the way for a more inclusive approach to psoriasis management.
Conclusion
For people of colour, living with psoriasis often comes with unique challenges that go beyond the physical signs and symptoms of the condition. Delayed diagnoses, misdiagnoses, and historical underrepresentation in research can exacerbate the burden of this chronic illness. However, initiatives like the Canadian Skin of Colour Consensus Forum offer hope by highlighting the need for greater inclusivity and representation in both research and clinical practice. By implementing the Forum’s recommendations and fostering a more culturally aware approach to care, we can move closer to a future where all individuals with psoriasis receive the timely and effective treatment they deserve.
