Treating clinicians interpreted CXR for the presence of PTX for therapeutic decisions. Lung ultrasound was later reviewed by ultrasound experts, and CXR was reviewed by a radiologist. We defined expert LUS interpretation as the reference standard. The sensitivity and specificity of resident\u2010performed LUS examinations for diagnosing PTX were calculated. We assessed agreement between trained resident versus expert LUS and clinician versus radiology CXR using the Cohen \u03ba coefficient. We compared the time to results between LUS and CXR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Over an 8\u2010month period, 51 participants were enrolled. Compared to expert LUS interpretation, the sensitivity and specificity (95% confidence intervals) of resident LUS were 100% (85%\u2013100%) and 96% (82%\u2013100%), respectively, whereas the sensitivity and specificity of clinician\u2010interpreted CXR were 48% (27%\u201369%) and 100% (88%\u2013100%). The agreement between resident and expert LUS was excellent (\u03ba = 0.96), whereas the agreement between clinician and radiologist CXR was only moderate (\u03ba = 0.60). The time to results was significantly longer for CXR than LUS (mean, 1335 versus 396 minutes; <jats:italic>P<\/jats:italic> = .0001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A resident\u2010performed LUS examination was a quicker imaging modality with superior sensitivity compared to clinician\u2010interpreted CXR for PTX follow\u2010up after tube thoracostomy in this Rwandan study.
