Prognostic score systems and community-acquired bacteraemic pneumococcal pneumonia

Abstract

The aim of this study was to evaluate the accuracy of three score systems: the pneumonia severity index (PSI); CURB-65 (confusion; urea >7 mM; respiratory rate ≥30 breaths·min^-1; blood pressure <90 mmHg systolic or ≤60 mmHg diastolic; aged ≥65 yrs old); and modified American Thoracic Society rule for predicting intensive care unit (ICU) need and mortality due to bacteraemic pneumococcal pneumonia.
