Outcomes of Integrated Practice Unit Treatment for Mild Traumatic Brain Injury and Co-occurring Conditions Among...

Area of Science:

• Neuroscience
• Psychiatry
• Rehabilitation Medicine

Background:

• Persistent symptoms after mild traumatic brain injury (mTBI) often co-occur with other health conditions, necessitating comprehensive treatment.
• Veterans represent a significant population experiencing chronic post-mTBI symptoms, impacting their quality of life.

Purpose of the Study:

• To evaluate the efficacy of an integrated practice unit (IPU) approach for treating veterans with chronic post-mTBI symptoms and co-occurring conditions.
• To assess the impact of an intensive outpatient program on patient-reported outcomes in this population.

Main Methods:

• Retrospective assessment of patient-reported outcomes using validated instruments including the Neurobehavioral Symptom Inventory (NSI) and PTSD Checklist for DSM-5 (PCL-5).
• Paired t tests and linear mixed models were employed to analyze changes in symptom scores from admission to post-discharge follow-up, controlling for demographic factors.

Main Results:

• Significant improvements were observed in total NSI, PCL-5, and Life Satisfaction Questionnaire-11 (LiSaT-11) scores from admission to discharge and 1 month post-discharge, with medium to very large effect sizes.
• Improvements in NSI and PCL-5 scores remained statistically significant after adjusting for demographic factors.
• Responder analyses indicated clinically meaningful improvements in mTBI and posttraumatic stress symptoms, with high endorsement of positive global change.

Conclusions:

• The integrated practice unit (IPU) model shows promise for managing persistent post-mTBI symptoms and co-occurring conditions in veterans.
• This multimodal approach led to significant symptom reduction and enhanced overall wellness in the studied veteran population.
