Severe community-acquired pneumonia: an Australian perspective.
Severe community-acquired pneumonia (CAP) is a common disease with a relatively high mortality. The initial treatment is empirical, based on a broad range of potential pathogens. There are minimal published data describing microbiological causes of pneumonia in Australia. ⋯ Severe CAP requiring ICU admission was associated with a mortality rate of 32%, despite appropriate antimicrobial therapy including a beta-lactam and a macrolide antibiotic in most cases. Causative organisms identified were similar to those found in previous studies. High rates of viral causes (28% of identified pathogens) were noted. Low rates of legionellosis and other atypical causes were found, most probably due to a lack of systematic testing for these agents.
