Causes and Factors Associated With Early Failure in Hospitalized Patients With Community-Acquired Pneumonia

Abstract
In recent years, our understanding of community-acquired pneumonia (CAP) has improved substantially, and many new practices have been introduced. Several new microbial causes have been described, antibiotic resistance among respiratory pathogens has increased worldwide, and new antibiotic agents have been introduced as therapy for CAP. However, despite these advances in diagnosis and treatment, the morbidity and mortality rates associated with this infection remain high. Most recent studies1-6 report complications in 15% to 50% of hospitalized patients and overall mortality of 10% to 20%.
