400% increase in MRSA among Children of Urban Poor

Link: UCSF Study Shows Sharp National Rise in Skin Infections, MRSA Suspected.

During that time period, office and emergency room visits for all skin infections rose from 8.6 million nationwide to 14.2 million, according to Adam Hersh, MD, PhD, lead author on the paper and a fellow in the divisions of general pediatrics and of pediatric infectious diseases at UCSF. The vast majority of that increase was attributable to visits for abscesses or cellulitis, which Hersh called the hallmark signs of infections from the variety of staph bacteria known as MRSA, or methicillin-resistant Staphylococcus aureus. Those infections rose from 4.6 million to 9.6 million during the study period. “This shows that community-acquired MRSA infections are occurring nationwide and affect all subsets of the population,” Hersh said. “But there clearly are some subsets that are disproportionately affected, such as children.“ The increase was predominantly seen among children and among patients who visit emergency rooms in urban areas at so-called safety net hospitals. Those are hospitals in which at least half of the patients receive Medicaid or are uninsured. From 1997 to 2005, the number of visits for abscesses or cellulitis nearly quadrupled in safety-net emergency departments, from 1.3 people per 1,000 total population to 4.9. Among children, the incidence nearly tripled from 10.1 patients per 1,000 children to 27.6. By contrast, incident rates among patients older than 45 rose less than 50 percent, from 27.9 to 41.3 patients per 1,000 adults in that age group.
