Emergency department (ED) visits for syncope are common and routine diagnostic testing is frequently low yield. Our objective is to determine whether recent guidelines emphasizing limiting hospitalization and advanced diagnostic testing to high-risk patients have changed patterns of syncope care. ⋯ Although the incidence of ED visits for syncope has increased, hospitalization rates have declined, without an adverse effect on ED revisits, possibly because of increased use of observation care. Use of advanced cardiac testing and neuroimaging has increased, driven by growth in testing of patients receiving observation and inpatient care.
