Early-onset Pneumonia After Out-of-hospital Cardiac Arrest

Impact of Early Diagnosis Algorithm for Early-onset Pneumonia Diagnosis on Prognosis of Patients With Out-of-hospital Cardiac Arrest

Early-onset pneumonia after out-of-hospital cardiac arrest is frequent. An association between early-onset pneumonia and an increase in morbidity has been reported in this population. The diagnosis of early-onset pneumonia inpatients with out-of-hospital cardiac arrest may be challenging as diagnosis criteria are unspecific in this setting. On the other hand some studies have reported an association between early antibiotics and better prognosis in patients with out-of-hospital cardiac arrest suggesting that early diagnosis and treatment of pneumonia would benefit to patients. Nonetheless, adminitration of antibiotics to any patients with out-of-hospital cardiac arrest would expose to antibiotic patients without infection and woould participate to increase in antibiotic resistance.

Therefore, the PP-ACR study aims to evaluate the impact of a diagnosis algorithm including blinded sampling protected brushes on early-onset pneumonia treatment and patient prognosis after out-of-hospital cardiac arrest.

This study is a single centre observational study with a before - after design.
