From July 2006 through June 2009 in the United States, emergency department visits for pneumonia accounted for 2.2 percent of all ED visits, according to a study in Academic Emergency Medicine.
Researchers identified the rate of pneumonia ED visits using the Nationwide Emergency Department Sample. Each year over the three-year study period, approximately seven to eight patients per 1,000 persons visited the ED for pneumonia. Overall, 39.3 percent of these visits were managed as "treat-and-release" outpatient visits, according to the study.
