Summary

Increasing emergence of multidrug resistant (MDR) bacteria worldwide is now considered one of the most urgent threats to global health. The association between increase of antibiotics consumption and resistance emergence has been well documented for all patients admitted to the Intensive care unit (ICU) who received antibiotic treatment and for patients treated for ventilator associated pneumonia (VAP). Reduction of use of antibiotics is a major point in the war against antimicrobial resistance. VAP is the first cause of healthcare-associated infections in ICU and more than half of antibiotics prescriptions in ICU are due to VAP. Once the diagnosis of pneumonia under MV has been made, initiation of antibiotic treatment must be prompt but there is no clear consensus on its duration. In the case of a good clinical response to treatment, it has been shown in some situations that short course antibiotics can be effective without side effects and antimicrobial stewardship initiatives can be applied successfully and effectively to the management of Community Acquired Pneumonia (CAP). The hypothesis is that an antimicrobial stewardship is possible in the treatment of VAP with no increase in the rate of all-cause mortality, treatment failure or occurrence of new episode of pneumonia. The objective is to investigate whether an antimicrobial stewardship for VAP based on daily assessment of clinical cure and antimicrobial discontinuation, if it is obtained, would be non-inferior in terms of all-cause mortality, treatment failure or occurrence of new episode of pneumonia. This study will be a prospective, national multicenter (31 centers), phase III, comparative randomized (1:1), single-blinded clinical trial comparing two management strategies of treatment of pneumonia on the basis of two parallel arms: Experimental group: Antimicrobial stewardship based on daily clinical assessment of clinical cure. Control group: standard management: duration of appropriate antibiotic therapy for confirmed VAP according to guidelines.

Detailed description

Increasing emergence of multidrug resistant (MDR) bacteria worldwide is now considered one of the most urgent threats to global health. The association between increase of antibiotics consumption and resistance emergence has been well documented for all patients admitted to the Intensive care unit (ICU) who received antibiotic treatment1 and for patients treated for ventilator associated pneumonia (VAP). Reduction of use of antibiotics is a major point in the war against antimicrobial resistance. VAP is the first cause of healthcare-associated infections in ICU and more than half of antibiotics prescriptions in ICU are due to VAP. Current international guidelines define VAP as a pneumonia occurring\>48 hours after endotracheal intubation and distinguishes early onset VAP occurring in the first five days after admission and late VAP, occurring after. Once the diagnosis of pneumonia under MV has been made, initiation of antibiotic treatment must be prompt but there is no clear consensus on its duration. In the case of a good clinical response to treatment, it has been shown in some situations that short course antibiotics can be effective without side effects and antimicrobial stewardship initiatives can be applied successfully and effectively to the management of Community Acquired Pneumonia (CAP). American guidelines strongly recommend a 7-day course of antibiotic therapy rather than a longer duration but remark that "there exist situations in which a shorter or longer duration of antibiotics may be indicated, depending upon the rate of improvement of clinical, radiologic, and laboratory parameters". The hypothesis is that an antimicrobial stewardship is possible in the treatment of VAP with no increase in the rate of all-cause mortality, treatment failure or occurrence of new episode of pneumonia. The objective is to investigate whether an antimicrobial stewardship for VAP based on daily assessment of clinical cure and antimicrobial discontinuation, if it is obtained, would be non-inferior in terms of all-cause mortality, treatment failure or occurrence of new episode of pneumonia. This study will be a prospective, national multicenter (31 centers), phase III, comparative randomized (1:1), single-blinded clinical trial comparing two management strategies of treatment of pneumonia on the basis of two parallel arms: Experimental group: Antimicrobial stewardship based on daily clinical assessment of clinical cure. Control group: standard management: duration of appropriate antibiotic therapy for confirmed VAP according to guidelines. The primary endpoint is a hierarchical endpoint with a first non-inferiority criteria and a second efficacy criteria.

Conditions

• Ventilator Associated Pneumonia

Interventions

Type	Name	Description
DRUG	Antimicrobial Stewardship	Antimicrobial stewardship based on daily clinical assessment of clinical cure. Discontinuation of appropriate antibiotic therapy antibiotics if criteria of clinical cure of confirmed pneumonia are met. Intensivists will perform clinical assessment daily in order to decide on the pursuit or discontinuation of antibiotic therapy.
DRUG	Standard management	Standard management: duration of appropriate antibiotic for confirmed pneumonia fixed for 7 days according to guidelines. In the control group, intensivists will perform clinical assessment daily, but the antibiotic will not be discontinued until 7 days whatever the clinical cure.
