Traumatic brain injury as a chronic disease: insights from the United States Traumatic Brain Injury Model Systems Research Program.

Traumatic brain injury (TBI) is a global health priority, associated with substantial burden. Historically conceptualised as an injury event with finite recovery, TBI is now recognised as a chronic condition that can affect multiple domains of health and function, some of which might deteriorate over time. Many people who have had a TBI remain moderately to severely disabled at 5 years, are rehospitalised up to 10 years post-injury, and have a reduced lifespan relative to the general population. Understanding TBI as a chronic disease process can be highly informative for optimising care, which has traditionally focused on acute care. Chronic brain injury care models must be informed by a holistic understanding of long-term outcomes and the factors that can affect how care needs evolve over time. The United States Traumatic Brain Injury Model Systems of Care follows up individuals with moderate-to-severe TBI for over 30 years, allowing characterisation of the chronic (2-30 years or more post injury) functional, cognitive, behavioural, and social sequelae experienced by individuals who have had a moderate-to-severe TBI and the implications for their health and quality of life. Older age, social determinants of health, and lower acute functional status are associated with post-recovery deterioration, while younger age and greater functional independence are associated with risky health behaviours, including substance misuse and re-injury. Systematically collected data on long-term outcomes across multiple domains of health and function are needed worldwide to inform the development of models for chronic disease management, including the proactive surveillance of commonly experienced health and functional challenges.

Screening substance abuse treatment clients for traumatic brain injury: prevalence and characteristics.

OBJECTIVES: To examine clinical characteristics of clients in state-funded substance abuse treatment who report traumatic brain injury with loss of consciousness (TBI-LOC). PARTICIPANTS: Adult clients (N = 7784) entering state-funded substance abuse treatment in a rural state during a 12-month period. MEASUREMENT TOOLS: Substance use and mental health problems were measured using the federal Substance Abuse and Mental Health Services Administration (SAMHSA) adaptation of the Addiction Severity index (ASI). A brain injury screening question was used to determine the number of TBI-LOCs in a client's lifetime. DESIGN: Cross-sectional study of intake characteristics as part of a state-mandated treatment outcome study. RESULTS: Almost one-third (31.7%) of substance abuse treatment clients reported 1 or more TBI-LOCs. The clients reporting 2 or more TBI-LOCs were more likely than clients with none or 1 TBI-LOC to have serious mental health problems (ie, depression, anxiety, hallucinations, and suicidal thoughts and attempts), trouble controlling violent behavior, trouble concentrating or remembering, and more months of use of most substances. When depression and anxiety were held constant, and controlling for race and gender, clients with TBI-LOC had more months of marijuana and tranquilizer use. CONCLUSIONS: Findings suggest that treatment providers may need to be attentive to the complex conditions that co-occur with TBI-LOC. Future research should examine whether there are differences in treatment outcome for clients reporting TBI-LOC.
