Occupational contact dermatitis: Retrospective analysis of North American Contact Dermatitis Group Data, 2001 to 2016

Background: Patch testing is an important diagnostic tool for suspected allergic contact dermatitis (ACD) in occupational settings. Objective: Provide an overview of occupational skin disease (OSD) and an analysis of occupational ACD in North American patients undergoing patch testing between 2001and 2016. Methods: Patients with OSD were analyzed for frequency of allergic reactions to a screening series of allergens, occupational relevance, location of skin disease, and exposure sources. Demographic, occupation, and industry information were recorded. Results: Of 38,614 patients evaluated, 4471 (11.6%) had OSD, of whom 3150 (70.5%) had ACD. The most common occupationally related allergens included rubber accelerators, preservatives, and bisphenol A epoxy resin. Hands (75.8%), arms (30.0%), and face (15.9%) were common sites of dermatitis. The occupations most affected were service workers and machine operators. Limitations: Our cohort may not reflect the general working population. Conclusion: This study identified common occupational allergens, exposure sources, and occupations/ industries at risk. This information may help the clinician evaluate and manage patients with occupational contact dermatitis. ( J Am Acad Dermatol 2022;86:782-90.)

Automated summary

This study provides an overview of occupational skin disease (OSD) and analyzes the cases of occupational allergic contact dermatitis (ACD) in North American patients undergoing patch testing. The study identified common occupational allergens, exposure sources, and occupations/industries at risk, which can help clinicians evaluate and manage patients with occupational contact dermatitis.
