Table 3 Results of Cox proportional hazards regression analysis

From: One year mortality of patients treated with an emergency department based early goal directed therapy protocol for severe sepsis and septic shock: a before and after study

Variable† Hazard ratio 95% CI P value
Received EGDT* 0.55 0.35-0.87 0.01
Lowest ED SBP 1.0 0.99-1.01 0.59
Highest ED RR 1.0 0.99-1.01 0.55
DD-ESRD** 1.5 0.95-2.3 0.08
Initial SOFA score 1.1 1.05-1.2 0.004
Received steroids*** 1.1 0.7-1.7 0.70
  1. CI = confidence interval; DD ESRD = dialysis dependent end stage renal disease; ED = emergency department; EGDT - early goal directed therapy; RR = respiratory rate; SBP = systolic blood pressure; SOFA = sequential organ failure assessment.
  2. * Patients in the pre-implementation group did not receive EGDT and those in the post-implementation group did receive EGDT.
  3. ** Refers to patient reported diagnosis established previous to index hospitalization.
  4. *** Refers to patients who received systemic corticosteroids during the index hospitalization.
  5. Dependent variable: one-year mortality.
  6. Model Analysis
  7. Log likelihood with all covariates = -613.
  8. Deviance chi-squared = 26.9, degrees of freedom = 6, P = 0.0001.
