ICU rehabilitation is associated with reduced long-term mortality from sepsis in patients with low skeletal muscle mass: a case control study

Abstract

Background: It is unclear whether intensive care unit (ICU)-rehabilitation reduces mortality from sepsis in low skeletal muscle mass. We evaluated whether the association of ICU-rehabilitation with mortality from sepsis differs between patients with and without low skeletal muscle mass. Methods: We retrospectively reviewed 516 patients with sepsis who were admitted to the ICU between June 2011 and August 2017. The skeletal muscle area at the level of the third lumbar vertebra was measured with CT on admission. Patients were divided into two groups (low skeletal muscle mass and non-low skeletal muscle mass), and clinical outcomes were compared in patients treated with ICU-rehabilitation and without ICU-rehabilitation within each subgroup. We used Cox regression to examine factors associated with 1-year mortality in each subgroup.
