Epidemiology and Changes in Mortality of Sepsis After the Implementation of Surviving Sepsis Campaign Guidelines.

PURPOSE: To determine the epidemiology and outcome of severe sepsis and septic shock after 9 years of the implementation of the Surviving Sepsis Campaign (SSC) and to build a mortality prediction model. METHODS: This is a prospective, multicenter, observational study performed during a 5-month period in 2011 in a network of 11 intensive care units (ICUs). We compared our findings with those obtained in the same ICUs in a study conducted in 2002. RESULTS: The current cohort included 262 episodes of severe sepsis and/or septic shock, and the 2002 cohort included 324. The prevalence was 14% (95% confidence interval: 12.5-15.7) with no differences to 2002. The population-based incidence was 31 cases/100 000 inhabitants/year. Patients in 2011 had a significantly lower Acute Physiology and Chronic Health Evaluation II (APACHE II; 21.9 ± 6.6 vs 25.5 ± 7.07), Logistic Organ Dysfunction Score (5.6 ± 3.2 vs 6.3 ± 3.6), and Sequential Organ Failure Assessment (SOFA) scores on day 1 (8 ± 3.5 vs 9.6 ± 3.7; P < .01). The main source of infection was intraabdominal (32.5%) although microbiologic isolation was possible in 56.7% of cases. The 2011 cohort had a marked reduction in 48-hour (7% vs 14.8%), ICU (27.2% vs 48.2%), and in-hospital (36.7% vs 54.3%) mortalities. Most relevant factors associated with death were APACHE II score, age, previous immunosuppression and liver insufficiency, alcoholism, nosocomial infection, and Delta SOFA score. CONCLUSION: Although the incidence of sepsis/septic shock remained unchanged during a 10-year period, the implementation of the SSC guidelines resulted in a marked decrease in the overall mortality. The lower severity of patients on ICU admission and the reduced early mortality suggest an improvement in early diagnosis, better initial management, and earlier antibiotic treatment.

Mortality Reduction and Long-Term Compliance with Surviving Sepsis Campaign: A Nationwide Multicenter Study.

PURPOSE: To determine the long-term degree of compliance with the Surviving Sepsis Campaign (SSC) bundles and related outcomes after an educational program in septic patients admitted to a network of intensive care units (ICU). METHODS: Prospective, observational, multicenter study in several ICUs during a 5-month period for evaluating the degree of compliance with the SSC bundles of resuscitation in the first 6 h (B6H) and management in the following 24 h (B24H). We compared the findings with those from a historical cohort at the same ICUs after an educational program (EDUSEPSIS) 5 years earlier. RESULTS: The study cohort comprised 231 episodes of severe sepsis and the historical cohort included 217. In the current cohort, we found a better compliance with B6H compared with the historical cohort (27.7% vs. 9.7%, P < 0.001), and lower compliance with B24H (4.3% vs. 12.9%, P < 0.001). ICU and in-hospital mortalities were reduced from 37.3% to 27.1% (P = 0.02) and from 45.3% to 36.7% (P = 0.06), respectively. This reduction occurred linearly with the number of B6H items completed (P for trend <0.001). All B6H measures were individually associated with lower ICU mortality. Measurement of plasma lactate, blood cultures, and administration of broad-spectrum antibiotics were associated with lower in-hospital mortality. No benefit was observed regarding B24H. CONCLUSIONS: Our study confirmed that an educational campaign aimed at early recognition and management of patients with severe sepsis improves compliance with management recommendations and hospital survival in the long term.
