Muscle along the spine on a CT scan to predict 3-month survival after septic shock

Official title: Association Between Muscle L3 CT Scan Muscle Derived Parameters of Muscle Function Upon Intensive Care Unit Admission and 3 Months Mortality After ICU Discharge for Patients Admitted for Septic Shock. The SIMS Study

Run by Centre Hospitalier Universitaire de Saint Etienne · NCT07483710 · Data updated 2026-11-12

This study tests whether measurements from a CT scan of the lower back muscles taken around ICU admission can help predict mortality 3 months after discharge for patients with septic shock.

Is this trial a fit for you?

Likely a good fit

Adults with septic shock who had a non-contrast CT scan within the specified time window around ICU admission and are eligible for social security.

Probably not a fit

Patients without a suitable prior or immediate post-admission CT scan or who do not meet eligibility criteria may not benefit from this assessment.

What this trial studies

This prospective study investigates whether quantitative and qualitative muscle measurements from a CT scan at the L3 level, taken near ICU admission, correlate with 3-month mortality in septic shock patients. It builds on prior findings that muscle mass and density relate to outcomes in critical illness, aiming to determine prognostic value in the ICU setting. The study uses non-contrast CT scans and aligns with standard ICU practice while focusing on patients with septic shock. Primary analysis will assess associations between muscle-derived parameters and subsequent mortality, with secondary observations on feasibility and potential clinical implications.

Why it matters

Potential benefit: If successful, the approach could help clinicians identify high-risk patients early and tailor care plans accordingly.

How similar studies have gone: Previous retrospective studies have linked muscle impairment with higher mortality, but prospective validation in this exact setting is limited and novel.
