Randomized Controlled TrialCURB-65, PSI, and APACHE II to assess mortality risk in patients with severe sepsis and community acquired pneumonia in PROWESS.
Patients with community-acquired pneumonia (CAP) comprised 35.6% of the overall phase 3 Recombinant Human Activated Protein C Worldwide Evaluation in Severe Sepsis (PROWESS) study and 33.1% of the placebo arm. We investigated the use of CURB-65, the Pneumonia Severity Index (PSI), and Acute Physiology and Chronic Health Evaluation II (APACHE II) prediction scores to identify the CAP population from the PROWESS placebo arm at the greatest mortality risk. ⋯ Despite early diagnosis and appropriate antibiotic therapy, conventionally treated CAP with PSI = 5, CURB-65 3, or APACHE II 25 has an unacceptably high mortality. In this study, PSI, CURB-65, and APACHE II scoring systems perform similarly in predicting the 28-day and in-hospital mortality; however, differences in the categorization of severe CAP were observed and there was a significant mortality in patients with a CURB-65 <3 and PSI <5.
