Pneumonia and Empyema in Emergency Departments in Children

Study Overview
=================
Brief Summary
-----------------
Describe the epidemiology of hospitalized pediatric pneumonia and pneumonia with pleural effusion: frequency, clinical and biological characteristics, responsible bacteria and pneumococcus place, antibiotic resistance, treatment, vaccine status.

Detailed Description
-----------------
The pneumonia observatory began in June 2009 and has included more than 15,000 children with pneumonia or pneumonia with pleural effusion (hospitalized or not) until May 2019. This study led to the publication of many articles in international peer-reviewed journals. Since June 2019, the scientific committee of the study met at the ESPID congress has decided to include only hospitalized patients. This amendment is justified for three reasons: Change in criteria for diagnosing pneumonia with increasing use of chest ultrasound Logistical aspects and workload of investigating centers too important Long-term impact of pneumococcal vaccine 13-valent especially marked for the most severe cases In this context, the purpose of this amended study is to enroll only the most severe cases of pneumonia, i.e. requiring hospitalization, in ICU or not. Since this study began in 2009, we have already enrolled hospitalized cases, we will have a baseline prior to the introduction of third-generation PCVs and we will be able to continue monitoring with data since 2009.
