Trial on a Strategy Combining Rapid Diagnostic Testing and Antimicrobial Stewardship to Improve Antibiotic Use in Patients with Hospital-acquired Pneumonia.

Automated microbiological diagnostic device based on multiplex PCR analysis, allowing detection of multiple pathogens and resistance markers in one hour from invasive and non-invasive respiratory samples

After clinical examination, routine biological tests will be performed. This includes blood culture, direct examination and culture of invasive or noninvasive respiratory samples, urinary antigen tests for Legionella and Pneumococcus, Influenza PCR on nasopharyngeal swabs (during the influenza season).
