Indeed, he noted, “previous U.S. population–based studies showed that people with AD have higher odds of [ED] utilization than the rest of the population.”
He and Ms. Kwa examined 2006-2012 data from the Nationwide Emergency Department Sample, which includes information on about 20% of all emergency visits in the United States.
During that period, there were 1.86 million ED visits with a primary diagnosis of AD. The annual weighted prevalence of primary diagnoses of AD stayed fairly stable through the period, ranging from 2,589 to 2,769 per 1 million visits. However, the weighted prevalence of secondary AD diagnoses grew steadily from 1,227 per 1 million visits in 2006 to 1,533 per 1 million visits in 2012.
The researchers estimated that the total cost of annual costs of AD-related ED visits grew from $86.9 million in 2006 to $172.8 million in 2012 (P less than .05).
