Contemporary Patterns of Multiple Organ Dysfunction in Trauma

Area of Science:

• Critical care medicine
• Trauma surgery
• Organ transplantation

Background:

• Multiple organ dysfunction syndrome (MODS) significantly impacts trauma patient outcomes.
• Distinct clinical presentations of MODS may influence prognosis and treatment.
• Differentiating between early resolving MODS (ERMODS) and prolonged MODS (PRMODS) is crucial for critically injured patients.

Purpose of the Study:

• To investigate if prolonged MODS (PRMODS) can be identified as a distinct clinical entity separate from early resolving MODS (ERMODS) in critically injured patients.
• To analyze the clinical characteristics and outcomes associated with PRMODS.

Main Methods:

• A prospective observational study included adult major trauma patients.
• MODS was defined by a Sequential Organ Failure Assessment (SOFA) score >5.
• PRMODS was defined as MODS lasting >7 days; time to recovery (TTR) was calculated based on SOFA scores.

Main Results:

• Of 595 patients, 285 had ERMODS (48%) and 184 had PRMODS (31%).
• PRMODS patients experienced more severe and protracted organ dysfunction (mean SOFA 11 vs. 6 on Day 2) and longer TTR (17 vs. 3 days).
• PRMODS was linked to higher rates of hepatic/renal dysfunction, infection, and mortality (22% vs. 7%).

Conclusions:

• Prolonged MODS (PRMODS) is a common and distinct clinical entity in trauma patients.
• PRMODS is associated with significantly worse patient outcomes, including increased mortality.
• PRMODS may serve as a critical endpoint in future trauma outcome studies.
