TARGET-REA: Empiric Antibiotic Therapy for Ventilator-acquired Pneumonia With Gram-negative Bacilli in Intensive Care
Study Details
Study Description
Brief Summary
this study aims to verify the adequacy of doses of antibiotics prescribed in clinical practice for the treatment of ventilated acquired pneumonia (VAP) in the intensive care unit (ICU) with the pharmacodynamic efficacy criteria considered relevant literature. The impact of these pharmacodynamic parameters on the clinical and microbiological VAP will be evaluated.

Outcome Measures
Primary Outcome Measures
- adequate antibiotics [28 days]
proportion of patients for whom the pharmacodynamic target defined a priori according to data from the literature is reached for each antibiotic anti Gram-negative bacillus used empirically activity (including β-lactams, fluoroquinolones and aminoglycosides)
Secondary Outcome Measures
- Bacterial species [28 days]
Bacterial species in question, defined as any bacteria isolated in significant amounts on the diagnostic breath sampling
- Distribution of the main pharmacodynamic parameters [28 days]
ratio of the peak serum level (Cmax) on the minimal inhibitory concentration (MIC), ie Cmax/MIC ratio (for aminoglycosides and fluoroquinolones): distribution in the population and proportion of patients with Cmax/MIC> 10 ratio of the Area Under the serum concentration time Curve (AUC) on the MIC, ie AUC/MIC ratio (for fluoroquinolones) : distribution in the population and proportion of patients with an AUC/MIC ratio> 125 percentage of time spent above the MIC between 2 injections, and trough/MIC ratio (for β-lactams): distribution in the population and proportion of patients with a T>MIC of 100% (intermittent infusion) or trough/MIC> 4 (continuous infusion)
- Eradication of gram negative bacilli responsible for VAP [28 days]
defined as a bacterial count from distal respiratory sample realized during the third day of treatment, less than the threshold for each isolated Gram negative bacilli initially beyond these thresholds
- Death [28 days]
- Number of days alive without mechanical ventilation [28 days]
- Clinical recovery [28 days]
defined as patient alive with Clinical Pulmonary Infection Score (CPIS) <8
- Score of organ failure (SOFA) [8 days]
repeated measures every 48h for 8 days
