Contact dermatitis is an inflammatory skin reaction triggered by direct contact with an allergen or irritant, affecting an estimated ~15-20% of the general population at some point in their lives. It is one of the most common occupational skin diseases, accounting for approximately ~90% of workplace skin conditions. There are two main types: irritant contact dermatitis, caused by substances that directly damage the skin, and allergic contact dermatitis, caused by an immune reaction to specific allergens. Common triggers include nickel, fragrances, preservatives, latex, poison ivy, and harsh chemicals. The condition presents with redness, itching, swelling, and sometimes blistering at the site of contact.
The Question We Asked
“I developed a red, itchy, blistering rash on both wrists right where my watch and bracelet sit. It started a few weeks ago and keeps getting worse. My doctor thinks it might be contact dermatitis from nickel. How do I figure out what’s causing it and stop it from coming back?”

What Each Model Got Right
GPT-4
Strengths: Accurately described the difference between irritant and allergic contact dermatitis and correctly identified nickel as the most common cause of allergic contact dermatitis. Explained patch testing as the gold-standard diagnostic tool and provided practical avoidance strategies including choosing jewelry labeled nickel-free or hypoallergenic.
Claude 3.5
Strengths: Provided a comprehensive and practical response, excelling at connecting the symptom distribution (bilateral wrists) to the likely cause (jewelry). Offered detailed avoidance strategies including clear nail polish as a barrier on metal surfaces, choosing surgical-grade stainless steel or titanium jewelry, and reading product labels for nickel content. Discussed treatment for the active rash including topical corticosteroids and cool compresses while emphasizing that identifying and avoiding the trigger is the most important long-term strategy.
Gemini
Strengths: Gave a clear explanation of how contact dermatitis develops and correctly identified nickel in jewelry as a common trigger. Recommended removing the suspected item as the first step.
Med-PaLM 2
Strengths: Provided clinically detailed information about the delayed-type hypersensitivity mechanism in allergic contact dermatitis, the patch testing process (TRUE test and extended panels), and cross-reactive allergens. Discussed systemic contact dermatitis and the role of dietary nickel restriction in severe cases.
What Each Model Got Wrong or Missed
GPT-4
- Did not discuss cross-reactivity between nickel and other metals
- Underemphasized the chronic nature of nickel allergy once sensitized
- Failed to mention dietary nickel as a potential factor in systemic reactions
Claude 3.5
- Could have included more clinical detail about the patch testing process
- Did not discuss systemic contact dermatitis from dietary sources
Gemini
- Oversimplified the condition without distinguishing irritant from allergic types
- Did not discuss patch testing for definitive diagnosis
- Failed to mention that nickel allergy is lifelong once developed
- Missed practical prevention strategies beyond simple avoidance
Med-PaLM 2
- Used overly technical immunological terminology
- Did not provide practical day-to-day prevention tips
- Could have better explained what the patch testing experience is like for patients
Red Flags All Models Should Mention
Patients with suspected contact dermatitis should seek medical evaluation if the rash is widespread or involves the face or genitals, if blistering is severe or the skin shows signs of infection such as warmth, pus, or increasing pain, if the rash does not improve after removing the suspected trigger and using over-the-counter hydrocortisone, if respiratory symptoms develop from inhaled allergens, or if the rash significantly impacts daily functioning or sleep. Severe allergic contact dermatitis may require oral corticosteroids or other prescription treatments.
When to Trust AI vs. See a Doctor
AI Is Reasonably Helpful For:
- Understanding the difference between irritant and allergic contact dermatitis
- Learning about common allergens and how to identify triggers
- Getting practical avoidance strategies for known allergens like nickel
- Understanding what patch testing involves
- Finding general guidance on managing mild contact dermatitis at home
See a Doctor When:
- The rash is severe, widespread, or not improving with avoidance and over-the-counter treatment
- Patch testing is needed to identify the specific allergen
- Prescription-strength topical or oral medications are needed
- The dermatitis is affecting your occupation or daily activities
- Signs of skin infection develop over the rash
Methodology
Each AI model received the identical patient scenario and was evaluated for accuracy, practical avoidance guidance, diagnostic information, and clarity. Scores reflect consensus ratings on a 1-10 scale. Visit our medical AI accuracy and symptom checker comparison pages for more.
Key Takeaways
- All four models correctly identified nickel as the probable trigger and explained the basics of contact dermatitis, but varied in practical prevention advice
- Claude 3.5 scored highest for its detailed, actionable avoidance strategies and patient-centered approach
- Contact dermatitis affects approximately ~15-20% of the population and is the most common occupational skin disease
- Nickel allergy is lifelong once sensitization occurs, making trigger avoidance essential
- AI tools can help patients understand contact dermatitis but cannot replace patch testing for definitive allergen identification
