What Is the Best Approach to the Nonresponding Patient with Community-Acquired Pneumonia?

Abstract

Treatment failure in community-acquired pneumonia (CAP) is the failure to normalize the clinical features (eg, fever, cough, sputum production), or nonresolving image in chest radiograph, despite antimicrobial therapy. The incidence of treatment failure in CAP has not been clearly established; according to several studies it ranges between 6% and 15%. The rate of mortality increases significantly, especially in those patients with severe CAP. It is important to be able to identify what patients are at risk for progressive or treatment failure pneumonia that may make them candidates for a more careful monitoring.
