The aim was to determine the prevalence of OH in an Australian ED population. Secondary outcomes included any associations of OH with symptoms, presenting complaints, patient demographics, or hospital admission, and the timing of OH findings.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients presenting to a regional Australasian ED underwent orthostatic measurements at 1, 3 and 5\u2009min of standing following 5\u2009min of supine bed rest. OH was defined as a drop in systolic and\/or diastolic blood pressure by \u226520 and \u226510\u2009mmHg, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 312 patients who were enrolled in the study, 69 (22.1%, 95% confidence interval 17.7\u201327.2%) had OH and 76.8% of cases were detected after 3\u2009min of standing. There was evidence of difference in the prevalence of OH with age (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001).
