Temporal patterns of organ dysfunction after severe trauma.

Area of Science:

• Critical Care Medicine
• Trauma Surgery
• Intensive Care Unit (ICU) Management

Background:

• Temporal patterns of organ dysfunction (OD) are crucial for recognizing complications post-trauma.
• Understanding these patterns can optimize treatment timing and modality in intensive care unit (ICU) trauma patients.

Purpose of the Study:

• To analyze and characterize the temporal patterns of organ dysfunction (OD) in trauma patients admitted to the ICU.
• To identify distinct trajectories of OD development and resolution in the early post-trauma period.

Main Methods:

• Group-based trajectory modeling was employed to identify temporal patterns of OD.
• The Sequential Organ Failure Assessment (SOFA) score subdomains were measured daily for the first two weeks post-trauma.
• Time to trajectory stabilization and final group assignment were evaluated.

Main Results:

• Five distinct OD trajectories were identified in 660 trauma patients.
• Trajectories ranged from mild OD with early resolution to extreme OD with sustained dysfunction and high mortality.
• Specific trajectories were associated with factors like Injury Severity Score (ISS), sepsis development, need for blood transfusions, shock, and traumatic brain injury (TBI).
• Groups 1 (mild OD) and 5 (TBI with OD) showed early stabilization, while Groups 2 and 3 (moderate/severe OD) had prolonged stabilization times.

Conclusions:

• Distinct temporal trajectories of OD exist in severe trauma patients within the first two weeks post-trauma.
• These findings highlight the heterogeneous clinical course following trauma.
• The identified groupings and temporal patterns offer potentially important clinical insights for patient management.
