Prospective Assessment of Improvement and Decline in Global Functioning After Traumatic Brain Injury Using Multistate...

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Public Health

Background:

• Traumatic brain injury (TBI) significantly impacts global functional status.
• Understanding long-term recovery patterns is crucial for patient care and resource allocation.

Purpose of the Study:

• To describe functional status transitions in the 10 years post-TBI.
• To determine probabilities of improvement, decline, and stability.
• To identify factors associated with these transitions.

Main Methods:

• Analysis of the TBI Model Systems National Database.
• Inclusion of 13,731 participants with TBI and at least two follow-up assessments within 10 years.
• Utilized multistate Markov models to estimate transition probabilities and hazard ratios.

Main Results:

• Functional stability was highest for those with Good Recovery (68.4% stable year 1-2).
• Improvement was common for individuals with Moderate or Severe Disability.
• Older age, non-White race, lower education, and public insurance were linked to decline and mortality.
• Female sex, higher education, private insurance, and better discharge function were protective.

Conclusions:

• Functional recovery after TBI is a dynamic process with a higher likelihood of improvement or stability than decline.
• Identified modifiable factors, such as education and insurance status, have policy implications for improving TBI recovery trajectories.
