Patch testing practices of American Contact Dermatitis Society members.
BACKGROUND
Patch testing is an important part of diagnosing allergic contact dermatitis although there is much variability in methodology among practitioners.


OBJECTIVE
We surveyed members of the American Contact Dermatitis Society (ACDS) to quantify time spent with patients with contact dermatitis; to characterize patch testing practices, including the Thin-Layer Rapid Use Epicutaneous (T.R.U.E.) Test; and to assess utilization of the Contact Allergen Replacement Database (CARD).


METHODS
An electronic survey was sent to all members of the ACDS.


RESULTS
Our survey was sent to the 600 members of the ACDS; 100 members participated (a response rate of 16.6%). Respondents used patch testing trays that contained an average of 62 allergens; 68% of respondents used the North American Contact Dermatitis Group series, and only 9% used the T.R.U.E. Test. Respondents' biggest criticism of the T.R.U.E. Test was its low number of allergens, and 94% of respondents used CARD regularly.


CONCLUSIONS
ACDS members used patch testing trays with many allergens. Despite the T.R.U.E. Test's popularity among general dermatologists and allergists, few ACDS members used it. Routine CARD usage should be encouraged.
