Multicenter Epidemiologic Study of Severe Community Acquired Pneumonia in China

November 1, 2018 updated by: Jieming QU, Ruijin Hospital
This study is aimed to understand the clinical characteristics, etiology and resistance phenotype of major pathogens of SCAP in China through multicenter and prospective investigation. Thus to provide epidemiological basis for improving the SCAP diagnosis and treatment protocol suitable for China.

Study Overview

Status

Unknown

Detailed Description

During the study period, all patients who are diagnosed with SCAP and meet the inclusion criteria in the participating unit should be enrolled in the study . At the end of the trial, each participating unit should complete at least 20 qualified cases, and all participating units should have a total of more than 300 qualified cases.

  1. Learn about the etiology of SCAP in China.
  2. Grasp the resistance phenotype and molecular epidemiology of major pathogens of SCAP in China.
  3. Know the important clinical characteristics of SCAP in China, including age, basic diseases, length of hospital stay, length of stay in ICU, duration of mechanical ventilation, clinical manifestations, imaging findings, complications, mortality, etc.
  4. Analyze and clarify the clinical risk factors of affecting SCAP mortality.
  5. Understand the current situation of antibiotic treatment of SCAP in China.
