Performance of New Diagnostic Methods in Older Adults With Pneumonia (PNEUMO)

February 5, 2026 updated by: Katherine Buck, Ohio State University

Establishing and Implementing Pneumonia Diagnosis in ED Older Adults: A Mixed Methods Approach

Create a clinical diagnostic pathway for older ED adults with pneumonia and its subgroups (bacterial, viral, and co-infection) and determine whether novel biomarkers improve diagnostic accuracy. The investigators will conduct a prospective observational trial of 250 ED patients ≥65 years old with suspected pneumonia. The investigators will perform analyses overall and by subgroups, seeking common models to ease adoption.
