A dedicated program with guideline to enhance sepsis care was launched in July 2014 in Emergency Department (ED) of two regional hospitals. The study aimed to evaluate the effectiveness of the interventional program for severe sepsis patients, in antibiotic delivery rate and survival outcome. It is a before-and-after interventional study with data from July to December 2013 and August 2014 to January 2015. A dedicated program for severe sepsis patients was introduced in July 2014. The outcome measures were blood culture rate, antibiotic administration rate in ED and mortality. Kaplan-Meier analysis and log-rank test was used for comparison of the survival. Multivariate Cox proportional hazards model was constructed to predict time to mortality adjusted for covariates. 64 patients were included, 31 patients were in the pre-intervention group whereas 33 post-intervention. Both blood culture rate (29% vs 72.7%; p<0.001) and antibiotics administration in ED (38.7% vs 72.7%, p=0.0011) were significantly increased. Survival outcome was significantly improved in patients receiving timely antibiotics in ED (log-rank test p=0.016). Antibiotics administered in ED had hazard ratio of 0.178 (95% CI 0.053 to 0.595; p=0.005) in the Cox Proportional hazard regression model with adjustment of covariates. Age (adjusted odds ratio 1.06, 95% CI 1.01 to 1.12, p=0.033) and initial hypotension (adjusted odds ratio 0.97, 95% CI 0.95 to 0.99, p=0.005) were significant predictors of mortality. A dedicated guideline for severe sepsis management could improve blood culture rate, early antibiotics administration in the emergency department. Patients received early antibiotic had better outcome and survival.
