RESUMEN
OBJECTIVE: To characterize health literacy among individuals with traumatic brain injury (TBI) at least a year postinjury and to explore its relationship to sociodemographic variables, injury severity, and cognition. SETTING: Community following discharge from inpatient rehabilitation. PARTICIPANTS: In total, 205 individuals with complicated mild to severe TBI who completed follow-up as part of a national longitudinal study of TBI and completed a web-based health literacy measure. DESIGN: Multicenter, cross-sectional, observational study. MAIN MEASURES: Health Literacy Assessment Using Talking Touchscreen Technology. RESULTS: Thirty-one percent of the sample demonstrated marginal/inadequate health literacy; 69% demonstrated adequate health literacy. A higher proportion of non-Hispanic White adults had adequate health literacy than non-Hispanic Black and Hispanic adults. Individuals with greater than a high school education were more likely to have adequate health literacy than those with a high school education or less. Better executive functioning performance was related to adequate health literacy. Better episodic memory performance was related to adequate health literacy, but only for those with complicated mild to moderate injury. CONCLUSIONS: A substantial proportion of individuals with TBI have marginal/inadequate health literacy, which may impact their understanding, appreciation, and use of health-related information and recommendations. While low health literacy may be preexisting, directly related to TBI, or a combination of both, it should be screened and considered by professionals when communicating with persons with TBI. Healthcare providers should tailor their communication approaches and presentation of health information, particularly for those with low health literacy.

OBJECTIVE: To examine the associations between health literacy and health outcomes among individuals with traumatic brain injury (TBI) at least a year post-injury. SETTING: Community following discharge from inpatient rehabilitation. PARTICIPANTS: A total of 205 individuals with complicated mild to severe TBI who completed a TBI Model Systems National Database follow-up interview and a web-based health literacy measure. DESIGN: A multicenter, cross-sectional, observational study. MAIN MEASURES: The Health Literacy Assessment Using Talking Touchscreen Technology (Health LiTT), number of comorbid conditions (Medical and Mental Health Comorbidities Interview [MMHCI]), perceived physical and mental health (PROMIS Global Physical and Mental Health subscales), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7). RESULTS: After controlling for sociodemographic, injury, cognition, and time post-injury, adequate health literacy was associated with higher odds of greater perceived physical health compared with participants with marginal/inadequate health literacy (odds ratio = 4.10; CI = 1.52-11.70]. Participants with inadequate/marginal health literacy had 3.50 times greater odds of depression (PHQ-9 ≥ 10) compared with those with adequate health literacy. Participants 45 years and older reported a greater number of MMHCI physical health conditions, but fewer MMHCI mental health conditions and GAD-7 anxiety symptoms compared with those who were younger. Non-Hispanic White participants and those with mild/moderate TBI were more likely to report a greater number of MMHCI mental health conditions compared with non-Hispanic Black participants or those with severe TBI. Greater time post-injury was associated with greater number of chronic physical and mental health conditions, and less odds of good-to-excellent perceived global mental health. CONCLUSIONS: Inadequate health literacy is associated with worse perceived physical health and greater depressive symptoms among adults with TBI. Greater efforts are needed to explore the mechanisms by which health literacy influences chronic disease management and mental health after TBI to improve postinjury health status and outcomes, particularly among those with limited health literacy skills.

OBJECTIVE: Obstructive sleep apnea (OSA) is a common sleep disorder in people with traumatic brain injury (TBI). Although sleep disturbances have been associated with an increased risk of suicide compared with the general population, the relationship between OSA and suicide risk after TBI is not well documented. In this study, we hypothesized that OSA diagnosis would predict suicide risk in veterans with TBI. SETTING: Five Veterans Affairs (VA) Polytrauma Rehabilitation Centers. PARTICIPANTS: Participants were drawn from the VA TBI Model Systems study, with follow-up interviews at year 1 ( n = 392), year 2 ( n = 444), year 5 ( n = 498), or year 10 ( n = 252) post-TBI (7.8%-14.5% follow-up attrition). DESIGN: This was a retrospective analysis from observational data using logistic regression with repeated measurements. Suicide ideation and suicide attempts were examined as outcomes at each follow-up to evaluate the relationship between OSA and suicide risk after adjusting for other risk factors determined a priori via literature review. MAIN MEASURES: Suicidal ideation (Patient Health Questionnaire-9 item 9), suicide attempt during the past year (self-reported), and OSA diagnosis (self-reported). RESULTS: Contrary to study hypotheses, OSA diagnosis had no statistically significant association with suicide ideation or attempt after accounting for known predictors. However, greater depression symptoms, headache severity, and pre-TBI suicidal ideation and attempts predicted suicide risk at follow-up after accounting for other predictors. CONCLUSIONS: Results of this study did not support a relationship between OSA and suicide risk, possibly due to methodological limitations of OSA measurement. Future research on this topic should include objective measures of OSA severity and OSA treatment including adherence. Although suicide is a low base rate occurrence, the impact is disastrous and further research is needed to mitigate suicide risk.

OBJECTIVE: To examine motor vehicle crash frequency and risk factors following moderate-to-severe traumatic brain injury (TBI). SETTING: Eight TBI Model Systems sites. Participants: Adults ( N = 438) with TBI who required inpatient acute rehabilitation. DESIGN: Cross-sectional, observational design. MAIN MEASURES: Driving survey completed at phone follow-up 1 to 30 years after injury. RESULTS: TBI participants reported 1.5 to 2.5 times the frequency of crashes noted in the general population depending on the time frame queried, even when accounting for unreported crashes. Most reported having no crashes; for those who experienced a crash, half of them reported a single incident. Based on logistic regression, age at survey, years since injury, and perception of driving skills were significantly associated with crashes. CONCLUSION: Compared with national statistics, crash risk is higher following TBI based on self-report. Older age and less time since resuming driving were associated with lower crash risk. When driving was resumed was not associated with crash risk. These results do not justify restricting people from driving after TBI, given that the most who resumed driving did not report experiencing any crashes. However, there is a need to identify and address factors that increase crash risk after TBI.

OBJECTIVE: Examine considerations and perceived barriers to return to driving, and their association with psychosocial outcomes among adults with traumatic brain injury (TBI) who were not driving. METHODS: 174 adults with moderate-to-severe TBI enrolled in the TBI Model System participated in this cross-sectional study. All participants were drivers prior to their TBI. Outcome measures included the Barriers to Driving Questionnaire, Disability Rating Scale, Patient Health Questionnaire-9, General Anxiety Disorder-7, and Satisfaction With Life Scale. Descriptive analyses examined considerations and barriers to driving, including differences associated with demographic characteristics. Moderation analyses investigated the extent to which disability moderated the relationship between barriers and psychosocial outcomes. RESULTS: Social barriers were the most strongly endorsed domain, whereas physical barriers were endorsed least. The profile of endorsements differed for men and women, and for Black and White participants, on both theoretical considerations in returning to drive and experiences of barriers in doing so. Disability level moderated the relationship between barriers to driving and depression and life satisfaction, but not anxiety. CONCLUSION: The experience of barriers to driving is differentially associated with psychosocial outcomes among nondriving adults with TBI. Adults with low disability appear to be at risk for distress, even compared to other nondrivers.

OBJECTIVE: Determine anxiety trajectories and predictors up to 10 years posttraumatic brain injury (TBI). DESIGN: Prospective longitudinal, observational study. SETTING: Inpatient rehabilitation centers. PARTICIPANTS: 2836 participants with moderate to severe TBI enrolled in the TBI Model Systems National Database who had ≥2 anxiety data collection points (N=2836). MAIN OUTCOME MEASURE: Generalized Anxiety Disorder-7 (GAD-7) at 1, 2, 5, and 10-year follow-ups. RESULTS: Linear mixed models showed higher GAD-7 scores were associated with Black race (P<.001), public insurance (P<.001), pre-injury mental health treatment (P<.001), 2 additional TBIs with loss of consciousness (P=.003), violent injury (P=.047), and more years post-TBI (P=.023). An interaction between follow-up year and age was also related to GAD-7 scores (P=.006). A latent class mixed model identified 3 anxiety trajectories: low-stable (n=2195), high-increasing (n=289), and high-decreasing (n=352). The high-increasing and high-decreasing groups had mild or higher GAD-7 scores up to 10 years. Compared to the low-stable group, the high-decreasing group was more likely to be Black (OR=2.25), have public insurance (OR=2.13), have had pre-injury mental health treatment (OR=1.77), and have had 2 prior TBIs (OR=3.16). CONCLUSIONS: A substantial minority of participants had anxiety symptoms that either increased (10%) or decreased (13%) over 10 years but never decreased below mild anxiety. Risk factors of anxiety included indicators of socioeconomic disadvantage (public insurance) and racial inequities (Black race) as well as having had pre-injury mental health treatment and 2 prior TBIs. Awareness of these risk factors may lead to identifying and proactively referring susceptible individuals to mental health services.

OBJECTIVE: To describe the self-reported needs of family caregivers of service members and veterans (SMVs) who sustained a traumatic brain injury (TBI) and to identify predictors of the unmet family caregiver needs. SETTING: Five Department of Veterans Affairs (VA) Polytrauma Rehabilitation Centers (PRCs). PARTICIPANTS: Family caregivers of SMVs enrolled in the VA PRC TBI Model Systems (TBIMS) national database who were within their first 5 years post-TBI ( n = 427). DESIGN: Observational study. MAIN OUTCOME MEASURE: The Family Needs Questionnaire-Revised (FNQ-R) was completed by each SMV's designated caregiver. ANALYSES: Descriptive analyses were conducted on the FNQ-R responses at the item, domain, and total score levels. Unadjusted univariable and adjusted multivariable regression models were fitted to identify predictors of total unmet needs and unmet family need domains. RESULTS: FNQ-R item-level and domain-level descriptive results indicated that health information was the most frequently met need domain. In contrast, emotional and instrumental support domains were the least often met. On average, family caregivers reported that 59.2% of the 37 FNQ-R needs were met at the time of the follow-up assessment. Regression models indicated that both the number of SMV-perceived environmental barriers and whether the SMV received mental health treatment within the past year predicted the number of unmet FNQ-R needs. SMV-reported environmental barriers predicted increased unmet needs in all 6 family caregiver domains, and SMV mental health treatment in the past year predicted more unmet family caregiver emotional support, community support, and professional support needs. CONCLUSIONS: The current findings can be used to inform policy and programming for VA and Department of Defense to proactively address the specific needs of families and caregivers experienced in the first 5 years post-TBI.

OBJECTIVE: Describe who is able to return to driving (RTD) after moderate-to-severe traumatic brain injury (TBI), when this occurs, who maintains that activity, and the association with outcome. DESIGN: Cross-sectional descriptive study. SETTING: Eight follow-up sites of the TBI Model Systems (TBIMS) program. PARTICIPANTS: 618 participants enrolled in the TBIMS and 88 caregivers (N=706). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A survey was completed from 1-30 years postinjury focusing on RTD. Descriptors included demographic information, injury severity, and current employment status. Outcome was assessed at the time of the interview, including depression, quality of life, functional status, and community participation. RESULTS: Of 706 respondents, 78% (Nâ¯=â¯552) RTD, but 14% (Nâ¯=â¯77) of these did not maintain that activity. Of those who RTD, 43% (Nâ¯=â¯192) did so within 6 months of the injury and 92% did so within 24 months postinjury. The percentage of people driving after TBI did not differ significantly based on age at time of injury or follow-up. There were significant differences between drivers and nondrivers with respect to severity of injury, seizures, race, education, employment, rural vs urban setting, marital status, and family income. We performed a multivariate logistic regression to examine the association between driving status and demographic variables, adjusting for other variables in the model. The strongest associations were with current employment, family income, race, seizures, and severity of injury. Driving was associated with greater community participation, better functional outcomes, fewer symptoms of depression, and greater life satisfaction. CONCLUSIONS: Over a span of 30 years, three-quarters of people experiencing moderate-to-severe TBI return to driving a personal vehicle, although not everyone maintains this activity. Employment, race, family income, and seizures are strongly associated with RTD.

OBJECTIVE: To identify predictors of driving status in service members and veterans 1 year following a traumatic brain injury (TBI). SETTING: The 5 Department of Veterans Affairs (VA) Polytrauma Rehabilitation Centers (PRCs). PARTICIPANTS: A total of 471 service members and veterans (128 with mild/complicated mild TBI and 343 with moderate/severe TBI) who received TBI-focused inpatient rehabilitation at one of the VA PRCs and who participated in a 1-year postinjury follow-up assessment. DESIGN: Secondary analysis from the Department of Veterans Affairs Polytrauma Rehabilitation Centers Traumatic Brain Injury Model Systems (VA PRC TBIMS) national database. MAIN MEASURES: Primary outcome was a single item that assessed driving status at 1 year postinjury. Predictor variables included demographics; sensory impairment, substance use, and employment status at time of injury; PTSD symptoms reported at study enrollment; and functional impairment rated at rehabilitation discharge. RESULTS: In unadjusted bivariate analyses, among those with a mild/complicated mild TBI, older age and greater functional impairment were associated with lower likelihood of driving. Among those with a moderate/severe TBI, discharge to a nonprivate residence, greater functional impairment, and higher PTSD symptoms were linked to lower likelihood of driving. Adjusted multivariate analyses indicated that functional impairment was uniquely associated with driving status in both TBI severity groups. After controlling for other predictors, self-reported PTSD symptoms, particularly dysphoria symptoms, were associated with lower likelihood of driving in both severity groups. CONCLUSION: Given the significance of clinician-rated functional impairment and self-reported PTSD symptoms to the prediction of driving status 1 year post-TBI among service members and veterans, rehabilitation efforts to improve functioning and reduce negative affect may have a positive impact on driving and community integration.

OBJECTIVE: To examine racial/ethnic disparities in community participation among veterans and active duty service members with traumatic brain injury (TBI). SETTING: Five Department of Veterans Affairs (VA) TBI Model Systems (TBIMS) Polytrauma Rehabilitation Centers (PRCs). Participants: Three hundred forty-two community-dwelling adults (251 White, 34 Black, and 57 Hispanic) with TBI enrolled in the VA TBIMS National Database who completed a 1-year follow-up interview. Mean age was 38.6 years (range, 19-84 years). DESIGN: Cross-sectional analysis of a prospective observational cohort study. Main Measures: Community participation at 1 year postinjury assessed by 3 domains of the Participation Assessment with Recombined Tools-Objective (PART-O): Out & About, Productivity, and Social Relations. RESULTS: Significant differences were observed among race/ethnicity groups in PART-O Productivity and Out & About domains without controlling for relevant participant characteristics; Productivity scores were significantly higher for non-Hispanic Black than for non-Hispanic White participants (t = 2.40, P = .0169). Out & About scores were significantly higher for Hispanic than for non-Hispanic White participants (t = 2.79, P = .0056). However, after controlling for demographic, injury severity, and 1-year follow-up characteristics, only differences in the Out & About domain remained statistically significant (t = 2.62, P = .0094), with scores being significantly higher for Hispanics than for non-Hispanic Whites. CONCLUSIONS: The results, which differ from findings from studies conducted in non-VA healthcare settings where there are greater racial/ethnic disparities in participation outcomes, could reflect differences between military and civilian samples that may reduce disparities.

OBJECTIVE: Describe driving patterns following moderate-to-severe traumatic brain injury (TBI). Participants: Adults (N = 438) with TBI that required inpatient acute rehabilitation who had resumed driving. DESIGN: Cross-sectional, observational design. SETTING: Eight TBI Model System sites. MAIN MEASURES: A driving survey was completed at phone follow-up. RESULTS: Most respondents reported driving daily, although 41% reported driving less than before their injury. Driving patterns were primarily associated with employment, family income, sex, residence, and time since injury, but not injury severity. Confidence in driving was high for most participants and was associated with a perception that the TBI had not diminished driving ability. Lower confidence and perceived loss of ability were associated with altered driving patterns. CONCLUSION: Most people with moderate-to-severe TBI resume driving but perhaps not at pre-injury or normal levels compared to healthy drivers. Some driving situations are restricted. The relationship between low confidence/perceived loss of ability and driving patterns/restrictions suggests people with TBI are exhibiting some degree of caution consistent with those perceptions. Careful assessment of driving skills and monitoring during early stages of RTD is warranted, particularly for younger, male, and/or single drivers who express higher levels of confidence.

OBJECTIVE: To examine the association between social Internet use and real-world societal participation in survivors of moderate-severe traumatic brain injury. DESIGN: Prospective cross-sectional observational study. SETTING: Ten Traumatic Brain Injury Model Systems Centers. PARTICIPANTS: A total of 331 participants in the Traumatic Brain Injury Model Systems, interviewed at any follow-up year between April 2014 and March 2015. MAIN MEASURES: Survey on Internet use, including social media and other online socialization; Participation Assessment with Recombined Tools-Objective with separate analyses of Productivity, Social Relations, Out and About subscales; covariates included demographics, injury variables, and functional and emotional status at follow-up. RESULTS: Participants were classified as social Internet users (N = 232) or nonusers (N = 99). Users had significantly higher Participation Assessment with Recombined Tools-Objective Social Relations scores than nonusers. A similar finding pertained to Out and About scores, with the between-group difference significantly greater for those with greater depressive symptoms severity. Users and nonusers did not differ significantly on Productivity subscale. CONCLUSIONS: The positive association between social Internet use and real-world social participation suggests that people with traumatic brain injury do not use social media as an alternative to real-world socialization. Rather, it is likely that similar barriers and facilitators affect both online and real-world social participation following traumatic brain injury. Emotional function should be considered as a moderating factor in further studies.

OBJECTIVE: To examine the relationships between caregiver resilience and a comprehensive set of sociodemographic and health-related quality of life (HRQOL) predictors among both caregivers and injured service members. DESIGN: Cross-sectional analysis of an observational cohort. SETTING: Community dwelling. PARTICIPANTS: Caregivers (n=87) who provide instrumental or emotional support to injured service members (n=73)(N=160). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The Connor-Davidson Resilience Scale 25-item version. RESULTS: Higher caregiver resilience scores were related to lower depressive symptom severity, greater health responsibility, physical activity, nutrition, spiritual growth, interpersonal relations, stress management, and problem-solving orientation. A multivariable regression model showed that spiritual growth and aspects of problem-solving orientation were significantly related to resilience. CONCLUSIONS: Results highlight the relationships between resilience and spirituality, problem-solving orientation, and aspects of HRQOL among caregivers of injured service members. These findings have important implications for caregiver behavioral health programs designed to promote resilience and draw upon caregiver strengths when taking on a caregiver role. Approaches that include a more integrative medicine or strengths-based emphasis may be particularly beneficial when working with families of injured military.

Objective: This study aimed to 1) describe and explore the experiences of sleep following a moderate or severe traumatic brain injury (TBI) in community-dwelling adults, 2) elicit factors that positively or negatively impact the sleep experience, and 3) understand sleep-related education provided to survivors.Design: Qualitative description.Methods: Face-to-face interviews with 16 individuals using a semi-structured interview guide. Transcripts were systematically coded and common themes were identified. The final sample consisted of primarily Caucasian men with average age of 32.4 years (SD = 9.9), and average of 2.6 years (SD = .89) years post injury.Results: Community-dwelling survivors of TBI experienced poor sleep quality and quantity post-injury and described a variety of approaches to manage their sleep. Survivors described coping with sleep changes and using sleep as a coping mechanism for TBI. Additionally, survivors' responses indicated perceived lack of resources and preference for receiving education from knowledgeable, familiar clinicians during face-to-face encounters.Conclusions: This study provides a description of reported sleep experiences following TBI and adds new knowledge regarding sleep management strategies and preferences for resources. The findings suggest a need for education regarding sleep for rehabilitation professionals and long-term sleep support after discharge from rehabilitation.

OBJECTIVES: To evaluate (1) the trajectory of resilience during the first year after a moderate-severe traumatic brain injury (TBI); (2) factors associated with resilience at 3, 6, and 12 months postinjury; and (3) changing relationships over time between resilience and other factors. DESIGN: Longitudinal analysis of an observational cohort. SETTING: Five inpatient rehabilitation centers. PARTICIPANTS: Patients with TBI (N=195) enrolled in the resilience module of the TBI Model Systems study with data collected at 3-, 6-, and 12-month follow-up. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Connor-Davidson Resilience Scale. RESULTS: Initially, resilience levels appeared to be stable during the first year postinjury. Individual growth curve models were used to examine resilience over time in relation to demographic, psychosocial, and injury characteristics. After adjusting for these characteristics, resilience actually declined over time. Higher levels of resilience were related to nonminority status, absence of preinjury substance abuse, lower anxiety and disability level, and greater life satisfaction. CONCLUSIONS: Resilience is a construct that is relevant to understanding brain injury outcomes and has potential value in planning clinical interventions.

OBJECTIVE: Examine the prevalence of weight classifications and factors related to obesity/overweight among persons 1 to 25 years following traumatic brain injury (TBI) using the Traumatic Brain Injury Model Systems national database. DESIGN: Multicenter, cross-sectional, observational design. SETTING: Traumatic Brain Injury Model Systems inpatient rehabilitation facilities. PARTICIPANTS: Persons (N = 7287) 1, 2, 5, 10, 15, 20, or 25 years after TBI who required inpatient acute rehabilitation. MAIN OUTCOME MEASURES: Body mass index, demographic characteristics, functional, health, satisfaction with life, and global outcomes. RESULTS: Overall postinjury weight prevalence rates were 23% obese, 36% overweight, 39% normal, and 3% underweight. Higher rates for obesity and overweight problems were associated with increasing time since injury. Younger (18-19 years) and older (80+ years) age, those in a vegetative state, and those reporting excellent health were less likely to be obese. Individuals with a history of hypertension, heart failure, or diabetes were more likely to be obese. CONCLUSIONS: Being obese or overweight presents a health risk in the years following rehabilitation for TBI. The findings support the need for longitudinal studies and highlight the advisability of monitoring weight and promoting healthy lifestyle behaviors over time in survivors of TBI.

OBJECTIVE: To describe change in body mass index (BMI) and weight classification 1-year post- traumatic brain injury (TBI) among Veterans and service members. DESIGN: Prospective observational cohort study. SETTING: VA Polytrauma Rehabilitation Centers. PARTICIPANTS: Veterans and service members (N = 84) enrolled in VA Traumatic Brain Injury Model Systems (VA TBIMS) study with BMI scores at enrollment and 1-year post-injury. INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: BMI scores from height and weight and weight classifications (underweight, normal weight, overweight, obese classes 1-3) defined by WHO. RESULTS: Twenty per cent were obese at time of injury and 24% were obese at 1-year post-injury. Cross-tab analyses revealed 7% of normal weight and 24% overweight participants at time of injury as obese Class 1 one-year post-injury. Univariate models found BMI and tobacco smoking at time of injury were significant predictors of higher BMI scores 1-year post-TBI. Multivariable models found BMI at time of injury and motor functioning, were significant predictors. Preinjury BMI, tobacco smoking and PTSD symptom severity predicted change in weight category. CONCLUSION: While obesity among service members and Veterans post-TBI is below national averages, trends in weight gain between time of injury and 1-year follow-up were observed. Implications for health promotion and chronic disease management efforts with regards to rehabilitation for injured military are discussed.

OBJECTIVE: To characterize and compare subgroups of survivors with assault-related versus self-inflicted traumatic brain injuries (TBIs) via firearms at the time of inpatient rehabilitation and at 1-, 2-, and 5-year follow-up. DESIGN: Secondary analysis of data from the Traumatic Brain Injury Model Systems National Database (TBIMS NDB), a multicenter, longitudinal cohort study. SETTING: Retrospective analyses of a subset of individuals enrolled in the TBIMS NDB. PARTICIPANTS: Individuals 16 years and older (N=399; 310 via assault, 89 via self-inflicted injury) with a primary diagnosis of TBI caused by firearm injury enrolled in the TBIMS NDB. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Disability Rating Scale, Glasgow Outcome Scale-Extended, sociodemographic variables (sex, age, race, marital status), injury-related/acute care information (posttraumatic amnesia, loss of consciousness, time from injury to acute hospital discharge), and mental health variables (substance use history, psychiatric hospitalizations, suicide history, incarcerations). RESULTS: Individuals who survived TBI secondary to a firearm injury differed by injury mechanism (assault vs self-inflicted) on critical demographic, injury-related/acute care, and mental health variables at inpatient rehabilitation and across long-term recovery. Groups differed in terms of geographic area, age, ethnicity, education, marital status, admission Glasgow Coma Scale score, and alcohol abuse, suicide attempts, and psychiatric hospitalizations at various time points. CONCLUSIONS: These findings have implications for prevention (eg, mental health programming and access to firearms in targeted areas) and for rehabilitation planning (eg, by incorporating training with coping strategies and implementation of addictions-related services) for firearm-related TBI, based on subtype of injury.

OBJECTIVE: To examine differences in patient outcomes across Traumatic Brain Injury Model Systems (TBIMS) rehabilitation centers and factors that influence these differences using hierarchical linear modeling (HLM). SETTING: Sixteen TBIMS centers. PARTICIPANTS: A total of 2056 individuals 16 years or older with moderate to severe traumatic brain injury (TBI) who received inpatient rehabilitation. DESIGN: Multicenter observational cohort study using HLM to analyze prospectively collected data. MAIN OUTCOME MEASURES: Functional Independence Measure and Disability Rating Scale total scores at discharge and 1 year post-TBI. RESULTS: Duration of posttraumatic amnesia (PTA) demonstrated a significant inverse relationship with functional outcomes. However, the magnitude of this relationship (change in functional status for each additional day in PTA) varied among centers. Functional status at discharge from rehabilitation and at 1 year post-TBI could be predicted using the slope and intercept of each TBIMS center for the duration of PTA, by comparing it against the average slope and intercept. CONCLUSIONS: HLM demonstrated center effect due to variability in the relationship between PTA and functional outcomes of patients. This variability is not accounted for in traditional linear regression modeling. Future studies examining variations in patient outcomes between centers should utilize HLM to measure the impact of additional factors that influence patient rehabilitation functional outcomes.

OBJECTIVE: To describe the rates and causes for rehospitalization over 10 years after moderate-severe traumatic brain injury (TBI), and to characterize longitudinal trajectories of the probability of rehospitalization using generalized linear mixed models and individual growth curve models conditioned on factors that help explain individual variability in rehospitalization risk over time. DESIGN: Secondary analysis of data from a multicenter longitudinal cohort study. SETTING: Acute inpatient rehabilitation facilities and community follow-up. PARTICIPANTS: Individuals 16 years and older with a primary diagnosis of TBI. MAIN OUTCOME MEASURES: Rehospitalization (and reason for rehospitalization) as reported by participants or proxy during follow-up telephone interviews at 1, 2, 5, and 10 years postinjury. RESULTS: The greatest number of rehospitalizations occurred in the first year postinjury (27.8% of the sample), and the rates of rehospitalization remained largely stable (22.1%-23.4%) at 2, 5, and 10 years. Reasons for rehospitalization varied over time: Orthopedic and reconstructive surgery rehospitalizations were most common in year 1, whereas general health maintenance was most common by year 2 with rates increasing at each follow-up. Longitudinal models indicate that multiple demographic and injury-related factors are associated with the probability of rehospitalization over time. CONCLUSIONS: These findings can inform the content and timing of interventions to improve health and longevity after TBI.
