Project to Improve the Diagnosis and Treatment Ability of Adult Severe Community Acquired Lower Respiratory Tract Infection

Project to Improve the Diagnosis and Treatment Ability of Adult Severe Community Acquired Lower Respiratory Tract Infection

1. Objective to understand the proportion of atypical pathogens in the pathogens of SCAP and AECOPD in urban hospitals in China.
2. Objective to investigate the antimicrobial resistance of atypical pathogens in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) and SCAP in urban hospitals.
3. Objective to master the important clinical characteristics of patients with acute exacerbation of SCAP and COPD caused by atypical pathogens and mixed infection in urban hospitals in China, and to put forward the experience judgment index.
4. Objective to evaluate the advantages of various diagnostic methods for atypical pathogens causing lower respiratory tract infection.
5. It is suggested that the current empirical treatment of SCAP and severe COPD in China should be improved.
