NEW ORLEANS - The epidemiology of occupational skin disorders may be undergoing substantial change, results of a large new study suggest.
Historically, dermatologic disorders have accounted for 10%-15% of all workplace injuries, and contact dermatitis represented more than 90% of all workers’ compensation claims for occupational skin disorders. But results of a new study conducted in a large, multisite occupational medicine program contradict both of these historical findings, Dr. Nita Kohli reported at the annual meeting of the American Academy of Dermatology.
The study included approximately 147,000 patients who were seen at Kaiser Permanente occupational medicine clinics located throughout Southern California during 2004-2008. Skin disorders accounted for just 1% of all workplace injuries, not the 10%-15% previously reported by other investigators. And burns – not contact dermatitis – made up the largest category of dermatologic claims.
Indeed, burns accounted for 65% of all workers’ compensation cases involving skin disorders, compared with contact dermatitis (20%), infections (9%), bites (4%), and "unspecified" (2%). About 90% of occupational dermatologic disorders among food workers were burns. In addition, burns accounted for the majority of skin injuries in all other occupational classes (including office jobs), with the sole exception of personal care jobs, in which burns were slightly outnumbered by cases of dermatitis, according to Dr. Kohli of the University of California, Los Angeles.
The occupational skin disorders caseload consisted of equal numbers of women and men. The average time to the first clinic visit was 12.1 days. Construction and production workers averaged 4.3 clinic visits per claim, compared with transportation workers (3.5), food workers (3.4), cleaning personnel (3.2), and health care workers (2.9).
The hands were the most frequently affected body part.
Burns resulted in an average of 4.3 lost workdays, compared with infections (4.2) and contact dermatitis (2.3). On average, patients lost 3.1 workdays because of their occupational skin disorder. Construction workers missed an average of 8.1 days of work, more than twice as many as did workers in any other occupational category.
The average treatment duration for patients with an occupational skin disorder was 33.5 days; contact dermatitis entailed by far the greatest average treatment length (53 days).
Dr. Kohli declared having no relevant financial disclosures.
