Mortality of Sepsis in Swedish Intensive Care Units 2008-2016

Completed

• Conditions: Sepsis

• Registration Number: NCT03489447
• Lead Sponsor: Uppsala University

Brief Summary

A study of short and long term mortality in patients treated with or without a diagnosis of sepsis in Swedish intensive care units (ICU) 2008 - 2016. The cohort is characterized with regard to chronic comorbidity, severity of acute illness and demographic factors, and outcome is adjusted for these factors. Changes in mortality during the period are studied.

Detailed Description

All adult patients admitted to a general ICU included in the Swedish Intensive Care Registry (a majority of all ICUs in Sweden) between 2008-01-01 and 2016-10-18 are followed for one year and any deaths are registered. Data on illness severity scores, age, sex, admitting hospital and duration of ICU stay are recovered. Data are linked with the inpatient registry of the Swedish Board of Health and Welfare (Socialstyrelsen), and any discharge diagnoses from the last 5 years preceding ICU admission are recovered. These are used to assess chronic comorbidity.

Mortality, adjusted for severity of illness, comorbidity and patient factors, is studied and any changes over time during the inclusion period are assessed.

The data in the Swedish ICU Registry are entered by the treating ICU physicians and include severity of illness (Simplified Acute Physiology Score (SAPS)3), selected chronic comorbidity, sex and date of birth, ICU stay and selected interventions and complications. Relevant International Classification of Diseases (ICD)-10 diagnoses are required and assessment of the occurrence of severe sepsis or septic shock, during the inclusion period defined according to the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) (sepsis 2) criteria, is mandatory when entering data.
