Posttraumatic Stress Disorder Symptoms Contribute to Staff Perceived Irritability, Anger, and Aggression After TBI in a Longitudinal Veteran Cohort: A VA TBI Model Systems Study

"Communication Is Not Exactly My Field, but It Is Still My Area of Work": Staff and Managers' Experiences of Communication With People With Traumatic Brain Injury

PURPOSE

Communication between people with traumatic brain injury (TBI) and rehabilitation staff can be impacted by cognitive-communication disorders. Communication partner training (CPT) programs hold potential to improve communication between people with TBI and their communication partners. To tailor CPT programs to the rehabilitation environment, it is critical to understand the nature of communicative interactions for staff members. This study explores staff and managers' experiences of communication with people with TBI in the rehabilitation setting.

METHOD

Individual semistructured videoconference interviews were carried out with staff members (n = 22) and managers (n = 4) varying in terms of professions and length of work experience. Interviews were guided by a phenomenological approach to gain comprehensive knowledge of staff and managers' lived experiences of communication with people with TBI.

RESULTS

Four themes with nine subthemes were generated: (a) cognitive-communication disorders challenge interaction (communication is socially inappropriate, the diversity of presenting symptoms associated with TBI is demanding), (b) staff struggle in communication (there is a breakdown of communicative collaboration, communication increases staff's workload, emotional well-being of staff is at risk), (c) communication context is crucial (tasks affect communication, extending the professional roles), and (d) staff want communication knowledge and skills (needs vary according to work experience, access to tailored strategies, and feedback).

CONCLUSIONS

Staff and managers experienced communication with people with TBI as highly demanding. The socially inappropriate communication in people with TBI was perceived to disturb the collaborative aspects of communication and create negative emotional impacts for staff. Staff experiences varied according to discipline, work experience, rehabilitation tasks, and facility. Consequently, staff and managers expressed a need for specific communication strategies to help them overcome the communicative challenges.

Putting the pieces together to understand anger in combat veterans and service members: Psychological and physical contributors

Dysregulated anger can result in devastating health and interpersonal consequences for individuals, families, and communities. Compared to civilians, combat veterans and service members (C-V/SM) report higher levels of anger and often have risk factors for anger including posttraumatic stress disorder (PTSD), traumatic brain injury (TBI), pain, alcohol use, and impaired sleep. The current study examined the relative contributions of established variables associated with anger (e.g., combat exposure, current PTSD symptoms, history of TBI, pain interference, and hazardous alcohol use) in 1263 C-V/SM. Sleep impairments, represented by poor sleep quality and obstructive sleep apnea (OSA) risk, were also evaluated as potential mediators of the relationships between established risk factors and anger, and therefore potential modifiable treatment targets. Multiple regression model results revealed that PTSD symptoms (β = 0.517, p < .001), OSA risk (β = 0.057, p = .016), pain interference (β = 0.214, p < .001), and hazardous alcohol use (β = 0.054, p = .009) were significantly associated with anger. Results of the mediation models revealed that OSA risk accounted for the association between PTSD and anger, in addition to the association between pain interference and anger. The current study extends previous literature by simultaneously examining factors associated with anger using a multivariable model in a large sample of C-V/SM. Additionally, treating OSA may be a novel way to reduce anger in C-V/SM who have PTSD and/or pain interference.

Rehabilitation Needs at 5 Years Post-Traumatic Brain Injury: A VA TBI Model Systems Study

OBJECTIVE

Describe rehabilitation needs and factors associated with unmet needs at 5 years post-traumatic brain injury (TBI).

SETTING

Five Veterans Affairs (VA) polytrauma rehabilitation centers (PRCs).

PARTICIPANTS

VA TBI Model Systems participants (N = 283; 96% male, 75%, 57% severe TBI).

DESIGN

Prospective observational cohort.

MAIN MEASURES

Rehabilitation Needs Survey (21-item survey that assesses cognitive, emotional, social, and functional needs); Craig Hospital Inventory of Environmental Factors (25-item survey of potential environmental barriers).

RESULTS

Participants endorsed a mean of 8 (SD: 6.2) ongoing and 3 (SD: 4.7) unmet rehabilitation needs at 5 years post-TBI. Approximately 65% of participants reported at least 1 rehabilitation need that remained unmet. The number and nature of needs differed across TBI severity groups. In unadjusted and adjusted linear regression models, Black race and environmental barriers (Craig Hospital Inventory of Environmental Factors total score) were predictive of unmet needs (P < .001). Those with greater unmet needs reported the physical environment (54%-63%), informational sources (54%), social attitudes (55%), healthcare access (40%), public policy (32%-37%), transportation availability (33%), and in-home assistance (32%) as the most frequent environmental barriers at 5 years post-TBI.

CONCLUSION

Veterans and Service Members continue to have rehabilitation needs at 5 years post-TBI. Veterans Affairs programs to address ongoing needs and policy to support them are needed.

The Traumatic Brain Injury Model Systems National Database: A Review of Published Research

The Traumatic Brain Injury Model Systems (TBIMS) is the largest longitudinal TBI data set in the world. Our study reviews the works using TBIMS data for analysis in the last 5 years. A search (2015–2020) was conducted across PubMed, EMBASE, and Google Scholar for studies that used the National Institute on Disability, Independent Living and Rehabilitation Research NIDILRR/VA-TBIMS data. Search terms were as follows: [“TBIMS” national database] within PubMed and Google Scholar, and [“TBIMS” AND national AND database] on EMBASE. Data sources, study foci (in terms of data processing and outcomes), study outcomes, and follow-up information usage were collected to categorize the studies included in this review. Variable usage in terms of TBIMS' form-based variable groups and limitations from each study were also noted. Assessment was made on how TBIMS' objectives were met by the studies. Of the 74 articles reviewed, 23 used TBIMS along with other data sets. Fifty-four studies focused on specific outcome measures only, 6 assessed data aspects as a major focus, and 13 explored both. Sample sizes of the included studies ranged from 11 to 15,835. Forty-two of the 60 longitudinal studies assessed follow-up from 1 to 5 years, and 15 studies used 10 to 25 years of the same. Prominent variable groups as outcome measures were “Employment,” “FIM,” “DRS,” “PART-O,” “Satisfaction with Life,” “PHQ-9,” and “GOS-E.” Limited numbers of studies were published regarding tobacco consumption, the Brief Test of Adult Cognition by Telephone (BTACT), the Supervision Rating Scale (SRS), general health, and comorbidities as variables of interest. Generalizability was the most significant limitation mentioned by the studies. The TBIMS is a rich resource for large-sample longitudinal analyses of various TBI outcomes. Future efforts should focus on under-utilized variables and improving generalizability by validation of results across large-scale TBI data sets to better understand the heterogeneity of TBI.

Evolution of Irritability, Anger, and Aggression after Traumatic Brain Injury: Identifying and Predicting Subgroups

The 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.
