Penn study finds healthcare disparity associated with common skin condition.

A new study shows white children in America are more likely to see a doctor for treatment of eczema than black children, despite the fact that the disease is likely more severe among minorities. Research from the Perelman School of Medicine at the University of Pennsylvania found black children with eczema were 30 percent less likely to see a doctor for their eczema than white children.

The study, published in the Journal of the American Academy of Dermatology, also found black children who see a doctor about the condition have more visits and receive more prescriptions than white children, indicating more severe disease.

There are several different types of eczema, and all told about 30 million Americans have some form of the disease. Data from the Centers for Disease Control shows roughly 11 percent of children experience eczema in the United States, with black children experiencing it more commonly (17.1 percent) than white children (11.2 percent) or Hispanic children (13.7 percent). In addition to the physical impact on the skin, eczema is associated with negative psychological effects.

“Previous studies have demonstrated disparities in overall healthcare utilization among racial and ethnic minorities, but few studies have examined this question specifically for eczema,” said the study’s senior author Junko Takeshita, MD, PhD, MSCE, an assistant professor of Dermatology and Epidemiology at Penn. “This is the first study to look at racial and ethnic differences in healthcare utilization for eczema on an individual level rather than relying on a sample of outpatient visits, making this a unique evaluation of eczema that includes those not accessing care for their disease.”

The study’s lead author was Alexander H. Fischer, MD, MPH, who was a medical student at Johns Hopkins University at the time of the research.

The researchers gathered data from the Medical Expenditure Panel Survey, the most complete source of data currently available on healthcare utilization, cost, and insurance coverage in the United States. All of the information is self- or caregiver-reported over a series of interviews, and is designed to be representative of the general population. The team used information from 2001 through 2013 for Americans under the age of 18 who identified themselves as white, black, or Hispanic. Those who identified in other groups did not make up a large enough sample for evaluation.

Based on data collected from 2,043 people with eczema, researchers estimated the data on a national scale. According to these estimates, of the nearly three million children with eczema represented in this study, 66 percent are white, 18 percent are black, and 16 percent are Hispanic. Overall, roughly 60 percent of these children have seen a doctor for their condition, but the percentages vary by race. Among white children, 62.1 percent saw a doctor. A similar proportion of Hispanic children (58.1 percent) saw a doctor for their eczema. However, the number dropped to just 51.9 percent for black children which, after accounting for baseline differences in sociodemographic factors and insurance status, translates to a 30 percent lower likelihood of seeing a doctor for their eczema than whites.

“The data show that race alone can be a predictor of whether or not a child with eczema will see a doctor, independent of other social or demographic factors or insurance status,” Takeshita said.

In addition, minority children reporting eczema were an average of a year to a year and a half younger. They were also less likely to have any private insurance, more likely to fall into the low income category, and more likely to have asthma relative to white children.

“While the study is not without its limitations, our findings suggest there are barriers to healthcare for eczema among black children
