研究概览
简要总结
A multicentric study to explore variability when clinicians are intrepreting lung function tests. Comparison with results of in-house built software for automatic interpretation.
详细描述
This is a multi-center non-interventional retrospective study that will use data obtained from clinical routine. In the hospital, subjects with or without respiratory complaints undergo subset of (or complete) pulmonary function tests if clinically indicated. Results of these tests, expressed as numerical values are send to the clinical workstation (KWS) for immediate clinical use. These results are subsequently being interpreted by a clinician.
A random sample of 50 lung function printouts of subjects followed at the Leuven pulmonary service with a final diagnosis of a respiratory disease have been randomised. These anonymized printouts will be given to different pulmonologists for examination in 18 different centers and compared with the interpretation of in-house developed software.
