Zusammenfassung: | Objectives
To determine 7 and 30-day mortality in consecutive patients with bacteraemic community-acquired pneumonia (CAP) and the association between predicted variables and likelihood of death.
Methods
From August 2007 to July 2011, demographic, clinical and microbiological data were prospectively collected on patients with bacteraemic CAP. Patients were followed until death, hospital discharge or recovery from infection. Univariate and multivariate analysis was performed to determine the association between predictor variables and 30-day mortality.
Results
7-day mortality was 61/252 [24.4 %, 95 % confidence interval (CI) 19.1–30.0 %] and by 30 days, this had risen to 77/252 (30.6 %, 95 % CI 24.9–36.6 %). In univariate analysis, factors associated with 30-day mortality were age, speciality within 48 h of admission, blood culture isolate and Charlson co-morbidity index (CCI). In multivariate analysis, age and CCI remained significantly associated. There was also a trend towards significance for meticillin-sensitive
Staphylococcus aureus
(MSSA) and
Pseudomonas aeruginosa
blood culture isolates compared to
Streptococcus pneumoniae
.
Conclusions
Overall, bacteraemic CAP was associated with high inpatient mortality. Because of their association with poor outcomes, patients with MSSA and
P. aeruginosa
bacteraemic CAP require further study. |
