Analysis of Pathogen in 460 Elderly Patients with Community Acquired Pneumonia

Objective： To research the changes of pathogen in elderly patients with community acquired pneumonia and to provide reference for rational use of antibiotics. Methods： Analyze clinical materials of 406 elderly patients with community acquired pneumonia. Results： 58.3% of patients＇ pathogen were identified. 69.31% of them are gram negative bacterial infection, and 27.94% of them are gram positive cocci infection. Conclusion： Etiological analysis should firstly be made before diagnosis and treatment of elderly patients with community acquired pneumonia, and specific medication should be designed according to the etiological analysis result, pharmacological function of antibiotics and particular conditions of each case.
