Treatment of community-acquired pneumonia in adults Tratamiento de la neumonía del adulto adquirida en la comunidad

Abstract

Appropriate antibiotic treatment reduces the duration of symptoms associated to pneumonia, the risk of complications and mortality. In most cases, it is not possible to identify the etiologic agent so antibiotic treatment is empirically prescribed. In Chile, one third of Streptococcus pneumoniae strain isolates has diminished susceptibility to penicillin; in-vitro erythromycin resistance is about 10-15% and cefotaxime resistance 2-10%. It is recommended to classify patients with community acquired pneumonia in four risk categories: Group 1: patients under 65 years without co-morbidities, in ambulatory attendance. Treatment: oral amoxicillin 1 g TID, 7 days. Group 2: patients over 65 years and / or co-morbidities, in ambulatory attendance. Treatment: oral amoxicillin/clavulanate 500/125 mg TID or 875/125 mg BID, or cefuroxime 500 mg BID, 7 days. Group 3: patients admitted to general wards with criteria of moderate severity. Treatment: ceftriaxone 1-2 g once a day or cefotaxime 1 g TID,
