Abstract

In order to enhance current knowledge of nosocomial and community-acquired bacteraemic pneumonia in a single tertiary hospital in Israel, a 7-year study was conducted. Using a computerised database, all patients who had bacteraemic pneumonia from March 1988 to August 1995 were studied. During the study period, pneumonia was the source of bacteraemia in 319 of 4,548 (7%) episodes, occurring in 295 patients; 211 (66%) episodes were community-acquired and 108 (34%) were nosocomial. The microoroganisms isolated most frequently from patients with community-acquired bacteraemic pneumonia were Streptococcus pneumoniae (46%), Staphylococcus aureus (10%) and Haemophilus influenzae (8%); while Pseudomonas spp. (17%), Klebsiella spp. (11%) and Staphylococcus aureus (10%) were isolated most often from the patients with nosocomial bacteraemic pneumonia. The median age of patients was 68 years (range, 0.003-100). The overall mortality was 34%. No significant difference was found between the mortality rates of patients with community-acquired (31%) and nosocomial (40%) bacteraemic pneumonia (P = 0.1). Multivariate analysis showed that hypothermia, respiratory failure, impaired consciousness, tracheal intubation, Staphylococcus aureus aetiology, septic shock, inappropriate empiric antibiotic treatment and age significantly increased mortality.
