Impact of Antimicrobial Stewardship on Outcomes of Patients With Hospital-acquired Pneumonia Due to Gram-negative Bacilli - A Before-after Study (ORACLE)
Impact of Antimicrobial Stewardship on Outcomes of Patients With Hospital-acquired Pneumonia Due to Gram-negative Bacilli - A Before-after ORACLE Study
Hospital-acquired pneumonia (HAP) is one of the most frequent complications and the main cause of antibiotics use in hospitalized patients, particularly in intensive care units (ICUs). The latest European and French recommendations for the management of HAP were published in 2017 and 2018. Gram-negative bacilli are frequently identified in this pneumonia.
The experts discussed the issue of tailored-empiric antimicrobial therapy. Because delayed antimicrobial therapy is associated with poor outcomes, their conclusion was to reduce the time to deliver proper antimicrobial therapy, but to limit over-use of broad-spectrum molecules. Since delays in microbiological identification hinder the ability of clinicians to streamline therapy, rapid diagnostic with multiplex PCR, which decreases the time to organism identification by 2 days compared to conventional methods, is appealing, especially for gram-negative bacilli. The FilmArray® Lower Respiratory Tract Infection Panel is a rapid multiplex PCR which tests for the most frequently pathogens (18 bacteria including plenty of gram-negative bacilli +5 genes of resistance, and 9 viruses) involved in HAP. The FilmArray® Lower Respiratory Tract Infection (LRTI) Panel has a sensitivity and a specificity of 95% and 99% respectively and can be implemented in a personalized antimicrobial guidance to treat HAP due to gram-negative bacilli. The investigators hypothesized that a rapid multiplex PCR for guidance of empiric antimicrobial therapy, especially for gram-negative bacilli, reduces the time-to-proper antimicrobial therapy and reduces the risk of death of patients suffering of HAP.
The investigators aim to assess the efficacy of an antimicrobial stewardship including the results of a rapid respiratory panel multiplex PCR for empiric antimicrobial guidance in patients with hospital-acquired pneumonia due to gram-negative bacilli.
The investigators will use a before-after design to test the efficiency of an antimicrobial stewardship including a highly innovative intervention.
