Identifying patients likely to have atopic dermatitis: development of a pilot algorithm.
BACKGROUND
A quick method to distinguish people who are predisposed to skin complaints would be useful in a variety of fields. Certain subgroups, such as people with atopic dermatitis, might be more susceptible to skin irritation than the typical consumer and may be more likely to report product-related complaints.


OBJECTIVE
To develop a rapid, questionnaire-based algorithm to predict whether or not individuals who report skin complaints have atopic dermatitis.


METHODS
A 9-item questionnaire on self-perceived skin sensitivity and product categories reportedly associated with skin reactions was administered to two groups of patients from a dermatology clinic: one with clinically diagnosed, active atopic dermatitis (n = 25) and a control group of patients with dermatologic complaints unrelated to atopic dermatitis (n = 25). Questionnaire responses were correlated with the patients' clinical diagnoses in order to derive the minimum number of questions needed to best predict the patients' original diagnoses.


RESULTS
We demonstrated that responses to a sequence of three targeted questions related to self-perceived skin sensitivity, preference for hypoallergenic products, and reactions to or avoidance of alpha-hydroxy acids were highly predictive of atopic dermatitis among a population of dermatology clinic patients.


CONCLUSIONS
The predictive algorithm concept may be useful in postmarketing surveillance programs to rapidly assess the possible status of consumers who report frequent or persistent product-related complaints. Further refinement and validation of this concept is planned with samples drawn from the general population and from consumers who report skin complaints associated with personal products.
