Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The time (in hours) on inappropriate antibiotic therapy based on multiplex bacterial PCR, recorded daily until discharge or 30 days follow-up | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Time to clinical stability; vital signs recorded at inclusion and daily up to discharge or up to 30 days, whichever happens first 2. Length of hospital stay in days, measured until discharge up to 30 days 3. Mortality, measured at 30 days follow-up 4. Adverse events and their relation to antibiotic therapy, assessed daily by history taking and any examination as clinically indicated up to discharge or up to 30-day observational period 5. Diagnostic performance of the multiplex bacterial PCR (HPN Pneumonia panel) as compared to conventional microbiologic testing and to a second confirmatory multiplex PCR, measured at the BAL day for the intervention group and after completion of the study (last visit, last patient out) for the control group 6. Diagnostic performance of multiplex PCR from BAL compared to multiplex PCR from sputa, measured after completion of the study (last visit, last patient out) for both randomized groups | — |
