Differential Pain Presentations Observed across Post-Traumatic Stress Disorder Symptom Trajectories after Combat...

Area of Science:

• Trauma and injury research
• Pain management
• Mental health outcomes

Background:

• Combat-related injuries can lead to long-term pain and post-traumatic stress disorder (PTSD).
• Understanding the relationship between PTSD symptom trajectories and pain is crucial for effective treatment.

Purpose of the Study:

• To evaluate the association between pain outcomes and PTSD symptom trajectories after combat injury.
• To assess the impact of regional anesthesia (RA) on pain and PTSD symptom trajectories.

Main Methods:

• Examined PTSD symptom trajectories in 288 combat-injured service members over two years.
• Used linear mixed-effects models to analyze the association between PTSD trajectories, pain, and RA receipt.

Main Results:

• Identified four PTSD trajectories: resilient, recovering, worsening, and chronic.
• Chronic and worsening PTSD trajectories were associated with significantly higher average pain scores and pain interference.
• Regional anesthesia (RA) was linked to improved pain outcomes but not PTSD trajectories.

Conclusions:

• Worsening and chronic PTSD trajectories correlate with increased pain intensity and interference post-combat injury.
• Early regional anesthesia (RA) shows potential for pain management but does not mitigate PTSD symptom trajectories.
• Integrated assessment and management of pain and PTSD symptoms are essential throughout trauma care.
