Investigators estimate that during 2012, there were more than 3.1 million emergency department visits for infectious diseases among elderly U.S. adults. This accounted for 13.5 percent of all emergency department visits of elderly adults, which was higher than visits for heart attacks and congestive heart failure combined. The rate of infectious disease-related emergency department visits was 7,231 per 100,000 elderly adults. The most common diagnoses were lower respiratory infections, urinary tract infections and septicemia.
Of all infectious disease-related emergency department visits, 57.2 percent resulted in hospitalization. Overall, 4.0 percent of patients died during their emergency department visit or hospitalization.
"With the rapid growth of the elderly population in the U.S., infectious diseases continue to be an important social problem. Our findings call for strategies to reduce infectious disease-related morbidity and healthcare utilization as a national priority for research, health policy, and community action," says Dr. Tadahiro Goto, lead author of the Journal of the American Geriatrics Society study.
