Pneumonia revealed in a cough
Date:6/27/2013

re classified as either pneumonic or non-pneumonic. The researchers used the overall clinical diagnosis provided by pediatric respiratory clinicians - aided with routine diagnostic technologies - to validate the sound analysis. From the analysis of cough sounds alone, this new technique was able to identify pneumonia cases with over 90 percent sensitivity, meaning that it identifies most patients who actually have pneumonia. In addition, it did so with a low false positive rate, outperforming the existing WHO algorithm for resource-poor regions.

The authors conclude: "Our results indicate the feasibility of taking a cough-centered approach to the diagnosis of childhood pneumonia in resource-poor regions. The technology, in its simplest version, will require between 5-10 cough sounds and will automatically and immediately provide a diagnosis without requiring physical contact with patients. Such a system, if successful, is expected to be a paradigm-shifting novelty in the field of pneumonia diagnosis in remote regions."
