Follow-up care after an emergency department (ED) visit due to asthma exacerbation can prevent future ED visits for asthmatic children, observes a new study led by researchers from UC San Francisco. The findings of the study, published online by Academic Pediatrics, found that about 5.7 percent of those with follow-up had a return asthma-related ED visit within 60 days, compared to 6.4 percent who didn’t have follow-up and that 25 percent of those with follow- up had a return ED visit compared to 28.3 percent who had no follow-up after 365 days. The researchers also pointed out that around 72,000 subsequent ED revisits could be prevented if follow-up is strictly in place for all visits.
