Item Demographic and Mental Health Predictors of Arrests Up to 10 Years Post-Traumatic Brain Injury: A Veterans Affairs TBI Model Systems Study(Wolters Kluwer, 2021-07) Miles, Shannon R.; Silva, Marc A.; Neumann, Dawn; Dillahunt-Aspillaga, Christina; Corrigan, John D.; Tang, Xinyu; Eapen, Blessen C.; Nakase-Richardson, Risa; Physical Medicine and Rehabilitation, School of MedicineOBJECTIVE: Examine rates and predictors of arrests in Veterans and Service Members (V/SM) who received inpatient rehabilitation for traumatic brain injury (TBI). SETTING: Veterans Administration (VA) Polytrauma Rehabilitation Centers. PARTICIPANTS: A total of 948 V/SM drawn from the VA TBI Model Systems cohort with arrest data up to 10 years post-TBI. DESIGN: Longitudinal cohort study; secondary analysis of pre-TBI characteristics predicting post-TBI arrests. MAIN MEASURES: Disclosure of arrests pre-TBI and up to10 years post-TBI. RESULTS: Thirty-six percent of the sample had been arrested prior to their TBI; 7% were arrested post-TBI. When considering all variables simultaneously in a multivariate model, pre-TBI mental health treatment (adjusted odds ratio [aOR] = 4.30; 95% confidence interval [CI]: 2.03-9.14), pre-TBI heavy alcohol use (aOR = 3.04; CI: 1.08-8.55), and number of follow-up interviews (aOR = 2.05; CI: 1.39-4.50) were significant predictors of post-TBI arrest. CONCLUSION: Arrest rates of V/SM prior to TBI were consistent with rates of arrest for people of similar ages in the United States. Post-TBI rates were lower for V/SM than published rates of post-TBI arrests in civilians with TBI. As part of rehabilitation planning for V/SM with TBI, providers should assess for preinjury mental health services and alcohol misuse to (1) identify those who may be at risk for postinjury arrests and (2) provide relevant resources and/or supports.Item Disorders of Consciousness due to Traumatic Brain Injury: Functional Status Ten Years Post-Injury(Mary Ann Liebert, 2018-09-18) Hammond, Flora M.; Giacino, Joseph T.; Nakase Richardson, Risa; Sherer, Mark; Zafonte, Ross D.; Whyte, John; Arciniegas, David B.; Tang, Xinyu; Physical Medicine and Rehabilitation, School of MedicineFew studies have assessed the long-term functional outcomes of patients with a disorder of consciousness due to traumatic brain injury (TBI). This study examined functional status during the first 10 years after TBI among a cohort with disorders of consciousness (i.e., coma, vegetative state, minimally conscious state). The study sample included 110 individuals with TBI who were unable to follow commands prior to inpatient rehabilitation and for whom follow-up data were available at 1, 2, 5, and 10 years post-injury. The sample was subdivided into those who demonstrated command-following early (before 28 days post-injury) versus late (≥ 28 days post-injury or never). Functional Independence Measure (FIM) at 1, 2, 5, and 10 years following TBI was used to measure functional outcomes. Measureable functional recovery occurred throughout the 10-year period, with more than two thirds of the sample achieving independence in mobility and self-care, and about one quarter achieving independent cognitive function by 10 years. Following commands prior to 28 days was associated with greater functional independence at all outcome time-points. Multi-trajectory modeling of recovery of three FIM subscales (self-care, mobility, cognition) revealed four distinct prognostic groups with different temporal patterns of change on these subscales. More than half the sample achieved near-maximal recovery by 1 year post-injury, while the later command-following subgroups recovered over longer periods of time. Significant late functional decline was not observed in this cohort. Among a cohort of patients unable to follow commands at the time of inpatient rehabilitation, a substantial proportion achieved functional independence in self-care, mobility, and cognition. The proportion of participants achieving functional independence increased between 5 and 10 years post-injury. These findings suggest that individuals with disorders of consciousness may benefit from ongoing functional monitoring and updated care plans for at least the first decade after TBI.Item Evolution of Irritability, Anger, and Aggression after Traumatic Brain Injury: Identifying and Predicting Subgroups(Liebert, 2021) Miles, Shannon R.; Hammond, Flora M.; Neumann, Dawn; Silva, Marc A.; Tang, Xinyu; Kajankova, Maria; Dillahunt-Aspillaga, Christina; Nakase-Richardson, Risa; Physical Medicine and Rehabilitation, School of MedicineThe current prospective, multi-center, longitudinal cohort study examined how veterans/service members (V/SM) changed in their irritability, anger, and aggression (IAA) scores from admission to discharge in post-acute rehabilitation settings. The goals were to identify trajectory subgroups, and explore if there were different predictors of the subgroups. V/SM (n = 346) from five Veterans Affairs TBI Model Systems Polytrauma Rehabilitation Centers participated. The sample was mostly men (92%) and identified as white (69%), black (13%), and other races (18%). Median age was 28 years, and 78% had sustained a severe TBI. Staff rated IAA at admission and discharge using the Mayo-Portland Adaptability Inventory-4 item#15. Four IAA trajectory subgroups were identified: (1) no IAA at admission or discharge (n = 89, 25.72%), (2) resolved IAA (n = 61, 17.63%), (3) delayed onset IAA (n = 31, 8.96%), and (4) persistent IAA (n = 165, 47.69%). Greater post-traumatic stress disorder (PTSD) symptoms were the only consistent predictor of belonging to all the subgroups who had IAA compared with the no IAA subgroup. We conclude that IAA had different trajectories after a TBI. The majority of V/SM had persistent impairment from IAA, a quarter of the sample had no impairment from IAA, and fewer participants had resolving or worsening IAA. Findings emphasize the importance of educating providers and family of the different ways and times that IAA can manifest after TBI. Timely diagnosis and treatment of PTSD symptoms during and after rehabilitation are critical treatment targets.Item Evolution of Irritability, Anger, and Aggression after Traumatic Brain Injury: Identifying and Predicting Subgroups(Mary Ann Liebert, 2021) Miles, Shannon R.; Hammond, Flora M.; Neumann, Dawn; Silva, Marc A.; Tang, Xinyu; Kajankova, Maria; Dillahunt-Aspillaga, Christina; Nakase-Richardson, Risa; Physical Medicine and Rehabilitation, School of MedicineThe current prospective, multi-center, longitudinal cohort study examined how veterans/service members (V/SM) changed in their irritability, anger, and aggression (IAA) scores from admission to discharge in post-acute rehabilitation settings.

Design Longitudinal cohort design. Setting Veterans Affairs Polytrauma Transitional Rehabilitation Programs. Participants Veterans and service members with TBI of all severity levels enrolled in the Veterans Affairs Polytrauma Rehabilitation Centers’ Traumatic Brain Injury Model System national database (N=240). Interventions Not applicable. Main Outcome Measure Univariable and multivariable logistic regression modeling was used to examine the association between irritability, anger, and aggression and potential risk factors, including PTSD symptoms. Irritability, anger, and aggression was measured as a single construct using an item from the Mayo-Portland Adaptability Inventory-4 that was rated by program staff at admission and discharge from the inpatient rehabilitation program. PTSD symptoms were assessed using the PTSD Checklist–Civilian Version. Results PTSD symptoms uniquely predicted program staff-rated irritability, anger, and aggression at discharge even after controlling for severity of TBI, age, male sex, education, and annual earnings. The model explained 19% of the variance in irritability, anger, and aggression. Conclusions When TBI severity and PTSD symptoms were considered simultaneously in a sample of veterans, only PTSD symptoms predicted staff-rated irritability, anger, and aggression. Given the negative outcomes linked with irritability, anger, and aggression, veterans may benefit from assessment and treatment of PTSD symptoms within rehabilitation settings.Item Relationship Stability After Traumatic Brain Injury Among Veterans and Service Members: A VA TBI Model Systems Study(Wolters Kluwer, 2017-07) Stevens, Lillian Flores; Lapis, Yanna; Tang, Xinyu; Sander, Angelle M.; Dreer, Laura E.; Hammond, Flora M.; Kreutzer, Jeffrey S.; O'Neil-Pirozzi, Therese M.; Nakase-Richardson, Risa; Physical Medicine and Rehabilitation, School of MedicineObjective: To explore stability of relationships and predictors of change in relationship status 2 years following TBI/polytrauma. Setting: Five Department of Veterans Affairs Polytrauma Rehabilitation Centers (VA PRCs). Participants: A total of 357 active duty service members and Veterans enrolled in the Veterans Affairs Polytrauma Rehabilitation Centers Traumatic Brain Injury Model Systems database with complete marital status information at 2 years postinjury. Design: Prospective, longitudinal, multisite. Main Measures: Relationship status change was defined as change in marital status (single/never married; married; divorced/separated) at 2-year follow-up, compared with status at enrollment. Results: At the time of enrollment, 134 participants (38%) were single/never married; 151 (42%) were married, and 72 (20%) were divorced/separated. Of those married at enrollment, 78% remained married at year 2 while 22% underwent negative change. Multivariable analyses revealed that age and education at the time of injury and mental health utilization prior to injury were significant predictors of relationship change. Among those who were single/divorced/separated at the time of enrollment, 87% remained so at year 2 while 13% underwent positive change. Injury during deployment significantly predicted positive relationship change. Conclusions: The unmalleable, preinjury characteristics identified may be used as potential triggers for education, prevention, surveillance, and couples therapy, if needed.
