Geriatric\u2010specific pneumonia diagnostic criteria exist for other settings; no prospective data exist to determine if application in the older adult ED population is feasible. The objective was to prospectively evaluate the utility of four current diagnostic criteria (Loeb; Modified McGeer; Infectious Disease Society of America\/American Thoracic Society; American College of Emergency Physicians) in older adult ED patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a prospective, observational cohort study of older adult ED patients \u226565\u2009years of age in two U.S. EDs with suspected pneumonia defined as having chest radiography ordered and treating physician suspicion. The standard we used for defining the presence, absence, or inability to determine a diagnosis of pneumonia diagnosis was expert physician chart adjudication. We report the summary statistics for demographic characteristics and symptoms\/exam findings and sensitivity, specificity, and likelihood ratios with 95% confidence intervals of the existing diagnostic criteria. Pre\u2010specified cutoff values of a positive LR\u2009&gt;10 and a negative LR\u2009&lt;0.3 were considered clinically significant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 135 patients enrolled, 27 had pneumonia by adjudicator review. Typical patient\u2010reported pneumonia symptoms, such as fever (18.5%) and new\/worse cough (51.9%), were not consistently present in pneumonia. The IDSA\/ATS and ACEP criteria had positive LR &gt;10 and negative LR\u2009&lt;0.3; however, all confidence intervals included pre\u2010specified cutoffs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Older adults presented to the ED with low frequency of typical pneumonia symptoms.
