Overall, 30-day mortality was 22%. In predicting mortality, the AUROC for CURB65 and CRB65 were superior compared with qSOFA, SIRS and NEWS in the all cause BSI (0.72, 0.70, 0.66, 0.51 and 0.53) and E. coli cohorts (0.81, 0.76, 0.73, 0.55 and 0.71). In the pneumococcal cohort, CURB65, CRB65, qSOFA and NEWS were broadly equal (0.63, 0.65, 0.66 and 0.62), but all were superior to SIRS (0.57). CURB65, CRB65 and qSOFA had considerably higher accuracy than SIRS or NEWS across all cohorts.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>CURB65 was superior to other scores in predicting 30-day mortality in the E. coli and all cause BSI cohorts.
