[Community-acquired pneumonia in adults. Clinical practice guideline for Argentina. Study Group on Community Acquired...

Community-acquired pneumonia (CAP) affects approximately 1% of the population annually. Initial antimicrobial therapy is most often empirical. Guidelines designed in other countries for the empirical management of CAP are not recommended for use in Argentina. Studies from other countries were considered together with unpublished local data to define the potential etiologic microorganisms and their antimicrobial susceptibility. Recommended diagnostic tests, groups of patients for different therapies and hospitalization criteria were defined. Severe CAP requiring intensive care was distinguished from the rest because of its distinct spectrum of etiologic agents and its high mortality, requiring a more focused therapy. Age, coexisting conditions and severity of illness were taken into account in the election of therapy.
