Clinical features predicting failure of pathogen identification in patients with community acquired pneumonia.

摘要: Community acquired pneumonia (CAP) is caused by a variety of microorganisms. By identifying patients at risk for failure pathogen identification, it possible to make an early decision on the extent diagnostic procedures be performed. This especially important in with severe CAP. The aim this study was identify these using clinical and laboratory features. In 201 hospitalized CAP, variables were collected. Pathogen identification performed culture sputum blood, urine antigen tests, polymerase chain reaction sputum, serological testing viral pharynx. 128 respiratory microorganism identified. both univariate multivariate analysis, predicted pre-hospital antibiotic therapy, medical history hypertension low C-reactive protein. We conclude that relatively protein are identification. These predictors should confirmed larger population. Invasive high-risk CAP presence considered phase hospitalization.
