Background: The aims of our study were to describe the nationwide epidemiology of sepsis requiring intensive care during an entire year and to evaluate compliance with treatment guidelines. Methods: This was a prospective, observational study of all adult patients admitted to Icelandic intensive care units (ICUs), who were screened for the ACCP/SCCM criteria for severe sepsis or septic shock on admission. Data were collected from 1 April 2008 to 31 March 2009. Results: One thousand five hundred and twenty‐four patients were admitted to the ICUs during the study year, 115 of them because of severe sepsis or septic shock. The incidence in Iceland was 0.48/1000 inhabitants ≥18 years per year [95% confidence intervals (CI) 0.42–0.55]. The mean APACHE II score was 20.7. Mortality was 24.6% (95% CI 17.5–33.3) at 28 days and 40.4% (95% CI 31.8–49.5) at 1 year. The main sources of infections were pulmonary (37%), abdominal (28%) and urinary tract (8%). Pathogens were gram‐positive (39%), gram‐negative (30%) and mixed (28%). No patient had sepsis caused by methicillin‐resistant Staphylococcus aureus or a monomicrobial fungal infection. Pulmonary infections were an independent predictor of death. Compliance to the resuscitation goals of the Surviving Sepsis Campaign ranged from 60% to 72% and the 6‐hour Sepsis Bundle was completed in 35% of patients. Conclusions: This nationwide study showed an incidence of 0.48/1000 inhabitants for severe sepsis and septic shock requiring intensive care therapy. The 28‐day mortality rate of 25 % was in the lower range of previous reports but the compliance to resuscitation goals and sepsis bundles was similar.
