title: Prognostic value of B-type natriuretic peptide with the sequential organ failure assessment score in septic shock.
abstract: BACKGROUND
  The aim of this study was to evaluate the prognostic value of B-type natriuretic peptide (BNP) in combination with the sequential organ failure assessment (SOFA) score in patients with septic shock at the time of emergency department (ED).
  
  
  METHODS
  Study subjects included all consecutive patients with septic shock who were treated with resuscitation bundle therapy between January 2010 and July 2012. SOFA scores and BNP were measured at ED recognition. The primary outcome was 28-day mortality. The area under the receiver operating characteristic curve was used to compare the predictive ability of SOFA score alone and in combination with BNP.
  
  
  RESULTS
  A total of 290 patients with septic shock admitted to ED were included. The BNP and SOFA score were higher in nonsurvival group compared with survival group (1,156.0 versus 469.1 pg/mL, P < 0.01; 9.9 versus 8.0, P < 0.01). In the receiver operating characteristic curves for predicting 28-day mortality, the area under the curves of SOFA score combined with BNP was 0.728 (95% confidence interval [CI]: 0.658-0.798) and SOFA score alone was 0.682 (95% CI: 0.610-0.755). Although the predictive ability of SOFA with BNP was statistically higher than that of SOFA alone (P = 0.02), it could not increase prognostic accuracy clinically significantly. SOFA with BNP was an independent predictor of 28-day mortality (odds ratio: 1.40, 95% CI: 1.15-1.71).
  
  
  CONCLUSIONS
  The combination of SOFA with BNP at the time of ED presentation may provide superior prognostic accuracy to the patients with septic shock. However, further studies need to validate the prognostic usefulness of SOFA with BNP.
