Body Mass Index and Outcomes in Patients with Severe Sepsis or Septic Shock

Abstract

The aim of this study was to investigate the association between body mass index (BMI) and survival in patients with severe sepsis or septic shock. Methods: We analyzed the sepsis registry of patients presenting to the emergency department (ED) of a tertiary urban hospital and meeting the criteria for severe sepsis or septic shock from August 2008 to March 2012. We categorized patients into the underweight group (BMI < 18.5 kg/m 2)
