Healthcare providers showed improved confidence and accuracy in interpreting patch tests for patients with skin of color (SOC) after completing a targeted educational module. This training helps reduce diagnostic disparities in allergic contact dermatitis.
Area of Science:
- Dermatology
- Allergology
- Medical Education
Background:
- Patch testing is crucial for diagnosing allergic contact dermatitis but presents interpretation challenges in patients with skin of color (SOC).
- Positive patch test reactions can manifest differently in SOC, potentially leading to diagnostic gaps due to limited specialized training.
Purpose of the Study:
- To develop and assess an online educational module aimed at enhancing healthcare providers' ability to recognize and interpret patch test reactions in SOC.
- The module focuses on improving diagnostic accuracy for allergic contact dermatitis in diverse patient populations.
Main Methods:
- An asynchronous, web-based educational module was created using clinical photographs across Fitzpatrick skin types I-VI.
- The module covered reaction grading, SOC-specific features, interpretation strategies, and relevant allergens, followed by pre- and post-intervention surveys for 40 healthcare providers.
Main Results:
- Significant increases in overall confidence and confidence specific to SOC patch test interpretation were observed.
- Recognition of SOC-specific erythema and reaction patterns improved by over 20 percentage points, with substantial knowledge gains regarding population-specific allergens.
- Participants found the educational materials highly beneficial.
Conclusions:
- The developed educational intervention effectively improved healthcare provider confidence and accuracy in interpreting patch tests for patients with SOC.
- Targeted training is valuable for reducing diagnostic disparities and improving dermatological care for diverse populations.
