The Etiology of Community-Acquired Pneumonia
Do Data Support the Guidelines?
Pneumonia is the eighth leading cause of death in the United States. Along with influenza, it causes more deaths globally than any other infectious disease.
Pneumonia (acute alveolar lung infection) presents with lung infiltrates and can be accompanied by fever, coughing, sputum production, physical evidence of consolidation, and elevated white blood counts. Adults aged 65 and older and children aged five and under are more likely to become ill with pneumonia. Some infections can be prevented with vaccines, and most respond to antibiotics or antiviral drugs.
Community-acquired pneumonia (CAP) is caused by bacterial, viral, fungal, or zoonotic organisms that produce mild to severe illness in people of all ages. Diagnosing CAP based on clinical presentation and chest X-ray findings can help guide empiric treatment with the safest and most narrow spectrum drug option.
In this P.A.C.E.-accredited Fisher Healthcare webinar, Daniel Musher, MD, will review the organisms currently thought to cause CAP, describe the role of normal respiratory flora as possible etiologic agents, and relate empiric therapy guidelines to the causative organisms.
Learning Objectives
This webinar will help you:
- Recognize organisms currently believed to cause CAP
- Describe the role of normal respiratory flora as possible etiologic agents of CAP
- Relate guidelines for empiric therapy to those organisms
