Summary
Predicting recovery after traumatic brain injury (TBI) is crucial. This study identified five distinct recovery trajectories for functional cognitive independence up to five years post-TBI, highlighting key influencing factors.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Public Health
Background:
- Early prediction of short- and long-term outcomes for traumatic brain injury (TBI) patients is a significant clinical challenge.
- Accurate outcome prediction is vital for effective discharge planning and resource allocation in acute trauma care.
- Understanding longitudinal recovery patterns is essential for optimizing patient care and rehabilitation strategies.
Purpose of the Study:
- To identify heterogeneous longitudinal recovery trajectories of functional cognitive independence over five years post-TBI.
- To reveal demographic, clinical, and injury-related factors associated with different recovery trajectory memberships.
- To inform early interventions and prevention strategies for improving TBI recovery outcomes.
Main Methods:
- Latent class growth analysis (LCGA) was used to classify recovery trajectories.
- Functional Independence Measure for Cognition (FIM-Cog) data from 8060 TBI patients were analyzed from discharge to 5 years post-injury.
- Backward stepwise multinomial logistic regression identified factors associated with trajectory membership.
Main Results:
- Five distinct recovery trajectories were identified: high independence, improved independence, delayed dependence, delayed independence, and low independence.
- Factors associated with delayed dependence included longer acute stays and a greater number of prior injuries.
- Factors linked to low independence included longer acute stays, narrower therapeutic windows, and a higher number of moderate-to-severe injuries.
Conclusions:
- LCGA effectively revealed five distinct patterns of functional cognitive independence recovery post-TBI.
- Identifying specific risk factors during acute care can guide targeted interventions.
- Understanding these trajectories and associated factors can optimize prevention and rehabilitation efforts for TBI survivors.
