Objective: To analyze the evolution of sepsis-related mortality in Spanish Intensive Care Units (ICUs) following introduction of the Surviving Sepsis Campaign (SSC) guidelines and the relationship with sepsis process-of-care.
Design: A prospective cohort study was carried out, with the inclusion of all consecutive patients presenting severe sepsis or septic shock admitted to 41 Spanish ICUs during two time periods: 2005 (Edusepsis study pre-intervention group) and 2011 (ABISS-Edusepsis study pre-intervention group).
Scope: Patients with severe sepsis or septic shock admitted to Spanish ICUs.
Patients: All ICU admissions from the emergency department or wards and all ICU patients with a diagnosis of severe sepsis or septic shock. A total of 1348 patients were included: 630 in the 2005 group and 718 in the 2011 group.
Intervention: None.
Primary endpoints: ICU mortality, 28-day mortality and Hospital mortality, hospital length of stay, ICU length of stay and compliance with the resuscitation bundle.
Results: Compliance with the resuscitation bundle was significantly greater in the 2011 group (5.7% vs. 9.9%; p=0.005), and was associated to lower mortality (OR 0.602 [0.365-0.994]; p=0.048). The 2011 group had lower absolute in-hospital mortality (44.0% vs. 32.6%; p=0.01), 28-day mortality (36.5% vs. 23.0%; p=0.01), and adjusted mortality (OR 0.64 [0.49-0.83], p=0.001).
Conclusions: Mortality related to severe sepsis or septic shock in Spain decreased between two patient cohorts in 2005 and 2011, and was attributable to earliness and improvement in sepsis care.
