Abstract
Background Recent studies have reported substantially decreased hospital mortality for sepsis, but data arescarceron outcomes after hospital discharge.We studied mortality up to one year in Swedish intensive careunit (ICU) patients with and without sepsis. Methods Demographic and medical data for all registered adult general ICU patients admitted between 01‐01‐2008 and 30‐09‐2016were retrieved from the Swedish Intensive Care Registryand linked with the National Patient Registerfor comorbidity data and the Cause of Death Register for death dates.The population was divided in two cohorts; 1. Patientswith a diagnosis of severe sepsis or septic shockand 2. All other ICU patients.Crude yearly mortality was calculated, andlogistic regression was used to analyse predictors of mortality. Results 28886 sepsisand 221941 nonsepsis ICU patients were identified. In the sepsis cohort, in 2008 unadjusted mortalitywas 32.6% at hospital discharge, 32.7% at 30 days, 39% at 90 days and 46.8% at 365 days.In 2016, mortality was 30.5% at hospital discharge, 31.9% at 30 days and 38% at 90 days. Mortality at 365 days was 45.3% in 2015. Corresponding non‐sepsis mortality was 15.4%, 16.2%, 20% and 26% in 2008 and 15.6%, 17.1%, 20.7% and 26.7% in 2016/2015.No consistent decrease in odds of mortality was seen in the adjusted analysis. Conclusions Mortality in severe sepsis and septic shock is high, with more than one in three patients not surviving three months after ICU admission,and adjusted mortality has not decreasedconvincingly in Sweden 2008 ‐ 2016.Keywords
