Characterization and Treatment of Chronic Pain After Traumatic Brain Injury-Comparison of Characteristics Between Individuals With Current Pain, Past Pain, and No Pain: A NIDILRR and VA TBI Model Systems Collaborative Project.

OBJECTIVE: To estimate the prevalence of chronic pain after traumatic brain injury (TBI) and identify characteristics that differ from those without chronic pain. SETTING: Community. PARTICIPANTS: A total of 3804 TBI Model Systems (TBIMS) participants who completed the Pain Survey at TBIMS follow-up. DESIGN: A multisite, cross-sectional observational cohort study. MAIN OUTCOME MEASURES: Functional outcomes, pain experience, and treatment. RESULTS: 46% reported current chronic pain, 14% reported past (post-injury) chronic pain, and 40% reported no chronic pain. Bivariate differences in sociodemographic and injury characteristics between the 3 pain groups were generally small in effect size, reflecting little clinical difference. However, medium effect sizes were seen for all functional outcomes, such that individuals with current chronic pain had worse functional outcomes compared with individuals in the past pain or no pain groups. Treatment utilization rates were higher for individuals with current chronic pain compared with past pain, with medical treatments being most frequently utilized. Individuals with past pain perceived more improvement with treatment than did those with current chronic pain as represented by a large effect size. CONCLUSIONS: Chronic pain affects approximately 60% of those living with TBI. The implications of chronic pain for functional outcomes support inclusion of pain metrics in prognostic models and observational studies in this population. Future research is needed to proactively identify those at risk for the development of chronic pain and determine the efficacy and access to pain treatment.

Associations of Chronic Pain With Psychosocial Outcomes After Traumatic Brain Injury: A NIDILRR and VA TBI Model Systems Collaborative Project.

OBJECTIVE: To examine the differences in participation, life satisfaction, and psychosocial outcomes among individuals with traumatic brain injury (TBI) endorsing current, past, or no chronic pain. SETTING: Community. PARTICIPANTS: Three thousand eight hundred four TBI Model Systems participants 1 to 30 years of age postinjury classified into 1 of 3 groups based on their pain experience: current pain, past pain, no pain completed a Pain Survey at their usual follow-up appointment which on average was approximately 8 years postinjury. DESIGN: Multisite, cross-sectional observational cohort study. MAIN OUTCOME MEASURES: Sociodemographic and injury characteristics and psychosocial outcomes (ie, satisfaction with life, depression, anxiety, posttraumatic stress disorder [PTSD], sleep quality, community participation). RESULTS: Persons with current chronic pain demonstrated higher scores on measures of PTSD, anxiety, and depression, and the lower scores on measures of sleep quality, community participation and satisfaction with life. Those with resolved past pain had mean scores for these outcomes that were all between the current and no chronic pain groups, but always closest to the no pain group. After adjusting for sociodemographic and function in multivariate analysis, having current chronic pain was associated with more negative psychosocial outcomes. The largest effect sizes (ES; in absolute value) were observed for the PTSD, depression, anxiety, and sleep quality measures (ES = 0.52-0.81) when comparing current pain to past or no pain, smaller ES were observed for life satisfaction (ES = 0.22-0.37) and out and about participation (ES = 0.16-0.18). When comparing past and no pain groups, adjusted ES were generally small for life satisfaction, PTSD, depression, anxiety, and sleep quality (ES = 0.10-0.23) and minimal for participation outcomes (ES = 0.02-0.06). CONCLUSIONS: Chronic pain is prevalent among individuals with TBI and is associated with poorer psychosocial outcomes, especially for PTSD, depression, anxiety, and sleep disturbance. The results from this study highlight the presence of modifiable comorbidities among those with chronic pain and TBI. Persons who experience persistent pain following TBI may be at greater risk for worse psychosocial outcomes.

Examining the Evidence From Single-Case Experimental Designs to Treat Challenging Behaviors Following Moderate to Severe Traumatic Brain Injury.

OBJECTIVE: To evaluate evidence on the effectiveness of behavioral interventions using single-case experimental design (SCED) methodology and to identify behavioral interventions with sufficient evidence for possible inclusion in the development of guidelines for the management of challenging behaviors in adults following moderate to severe traumatic brain injury (TBI). METHODS: As a subinvestigation of a larger systematic review process designed to identify evidence for guidelines development, the current review focused on studies using SCED methodology applied to persons with challenging behaviors following moderate to severe TBI. Articles were identified from a search of the published literature through January 2021, identifying studies in CINAHL, Cochrane Database of Systematic Reviews, EMBASE, MEDLINE/Ovid, and PsycINFO. Articles meeting inclusion criteria were assessed for design rigor to allow for effect size determination. The identified cases were then critically appraised using the RoBiNT (Risk-of-Bias in N-of-1 Trails) Scale to determine strength of evidence for causal inference. RESULTS: Thirty-four studies met inclusion criteria, with a total of 44 cases evaluated for effect of the treatment intervention on defined target behaviors. Seventeen cases had effect sizes rated as large, 22 cases as medium, 3 cases as small, and 3 as no effect. An observed trend was for large and medium effect sizes to be associated with lower RoBiNT Scale internal validity scores. Randomization, blinded provider and assessor, and assessment of treatment adherence were the internal validity items unlikely to meet criteria. CONCLUSIONS: SCED methodology was found to produce large and medium effect sizes for behavioral interventions targeting challenging behaviors following moderate to severe TBI. However, the strength of the evidence is limited because of weaknesses in study designs. Most of the studies failed to meet established internal validity criteria designed to reduce risk of bias in SCED studies as such rigor is difficult to establish or often not practical in clinical settings. Suggestions and recommendations are outlined for improving the quality of published cases using SCED methodology, which, in turn, will improve credibility of evidence and better inform the development of treatment guidelines for behavior regulation.

The use of assisted technologies in early aggressive mobilization with an individual in a minimally conscious state: a case report.

INTRODUCTION: Early neurorehabilitation and passive, upright mobilization strategies have been shown to be beneficial for individuals with disorders of consciousness (DOC). However, literature is limited in illustrating the use of an early, aggressive program with an added focus on dynamic and active upright mobilization. The purpose of this case report is to describe a two-week aggressive, upright standing and walking program with an individual with traumatic brain injury in an acute inpatient rehabilitation setting. The case investigates the association between aggressive mobilization with changes in level of consciousness and daily cognitive, motor and communicative behaviours. CASE DESCRIPTION: A 30-year-old male classified in DOC as minimally conscious state (MCS) participated in an early upright mobilization program. The two-week intervention consisted of aggressive static/passive and dynamic/active upright mobilization activities, involving a multidisciplinary rehabilitation team. Expressive communication, motor responses and current level of consciousness were monitored and assessed twice a day. Additionally, the patient's activation and arousal were subjectively monitored during daily therapy sessions. RESULTS: Following the dynamic/active mobilization activities, the patient demonstrated improved expressive communication, motor scores and increased activation and arousal during the mobilizations. After the two-week intervention, he emerged from DOC. CONCLUSION: This case report illustrates intense, more active/dynamic upright mobilization with the use of assisted technologies provides promise as an effective intervention for improving communication, motor responses, arousal and level of consciousness in a patient in MCS. Initiating upright, active activity sooner in the recovery process, may lead to improved outcomes and quicker emergence.IMPLICATIONS FOR REHABILITATIONAggressive upright mobilization may be delivered safely to patients in DOC early in their rehabilitative care.Aggressive upright mobilization may be beneficial for patients in DOC.Higher intensity, more active/dynamic upright mobilization such as the use of Erigo®Pro + stepping and locomotor training on a treadmill with body weight support demonstrated positive outcomes with expressive communication, motor responses and arousal.Earlier initiation of aggressive mobilization may promote recovery.

Traumatic Brain Injury Rehabilitation Outcome Prediction Using Machine Learning Methods.

Objective: To investigate the performance of machine learning (ML) methods for predicting outcomes from inpatient rehabilitation for subjects with TBI using a dataset with a large number of predictor variables. Our second objective was to identify top predictive features selected by the ML models for each outcome and to validate the interpretability of the models. Design: Secondary analysis using computational modeling of relationships between patients, injury and treatment activities and 6 outcomes, applied to the large multi-site, prospective, longitudinal observational dataset collected during the traumatic brain injury inpatient rehabilitation study. Setting: Acute inpatient rehabilitation. Participants: 1946 patients aged 14 years or older, who sustained a severe, moderate, or complicated mild TBI, and were admitted to 1 of 9 US inpatient rehabilitation sites between 2008 and 2011 (N=1946). Main Outcome Measures: Rehabilitation length of stay, discharge to home, FIM cognitive and FIM motor at discharge and at 9-months post discharge. Results: Advanced ML models, specifically gradient boosting tree model, performed consistently better than all other models, including classical linear regression models. Top ranked predictive features were identified for each of the 6 outcome variables. Level of effort, days to rehabilitation admission, age at rehabilitation admission, and advanced mobility activities were the most frequently top ranked predictive features. The highest-ranking predictive feature differed across the specific outcome variable. Conclusions: Identifying patient, injury, and rehabilitation treatment variables that are predictive of better outcomes will contribute to cost-effective care delivery and guide evidence-based clinical practice. ML methods can contribute to these efforts.

Lifetime history of TBI with loss of consciousness and disability among Appalachian and rural residents: 2016-2019 Ohio BRFSS.

BACKGROUND: While lifetime history of traumatic brain injury (TBI) is associated with increased risk of disabilities, little is known about disability and TBI among Appalachian and other rural residents. This study aimed to examine if the relationship between lifetime history of TBI with loss of consciousness (LOC) and disability differs by location of living (Appalachian vs. non-Appalachian; rural vs. urban). METHODS: We obtained data on lifetime history of TBI with LOC, location of living, and six sources of disability (auditory, visual, cognitive, mobility, self-care related, and independent living-related impairments) from the 2016-2019 Ohio Behavioral Risk Factor Surveillance System. We modeled the disability outcomes with Appalachian living (or rural living), lifetime history of TBI with LOC, and their interaction as independent variables. RESULTS: Of the 16,941 respondents included, 16.9% had a lifetime history of TBI with LOC, 19.5% were Appalachian residents and 22.9% were rural residents. Among Appalachian residents, 56.1% lived in a rural area. Appalachian (ARR = 1.92; 95%CI = 1.71-2.13) and rural residents (ARR = 1.87; 95%CI = 1.69-2.06) who had a lifetime history of TBI with LOC were at greater risk for having any disability compared to non-Appalachian and urban residents without lifetime history of TBI with LOC, respectively. CONCLUSIONS: Appalachian and rural living and lifetime history of TBI with LOC are risk factors for disability. Future research and health policies should address mechanisms for this risk as well as access to healthcare services following a TBI among Appalachian and rural residents.

Rural-Urban Differences in Behavioral Outcomes among Adults with Lifetime History of Traumatic Brain Injury with Loss of Consciousness: 2016-2019 Ohio BRFSS.

This study examined if the associations between lifetime history of traumatic brain injury (TBI) with loss of consciousness (LOC) and unhealthy alcohol use or mental health problems differ by location of living (rural vs. urban). The lifetime history data of TBI with LOC, location of living, unhealthy alcohol use (binge drinking, heavy drinking), and mental health problems (depression diagnosis, number of poor mental health days) were sourced from the 2016, 2017, 2018, and 2019 Ohio Behavioral Risk Factory Surveillance Surveys, and the final sample included 16,941 respondents. We conducted multivariable logistic regressions to determine the odds ratios for each of the five outcomes between individuals living in rural vs. urban areas and between individuals with vs. without a lifetime history of TBI with LOC. No interaction between location of living and lifetime history of TBI with LOC was observed for any outcomes, indicating rurality did not modify these relationships. Living in a rural area was associated with decreased binge drinking or heavy drinking but not mental health outcomes. Lifetime history of TBI with LOC was associated with an increased risk of binge drinking, heavy drinking, depression diagnoses, and poor general mental health, regardless of location of living. Our findings support the need for TBI screenings as part of mental health intake evaluations and behavioral health screenings. Though rurality was not associated with mental health outcomes, rural areas may have limited access to quality mental health care. Therefore, future research should address access to mental health services following TBI among rural residents.

Quasi-Contextualized Speech Treatment in Traumatic Brain Injury Inpatient Rehabilitation: Effects on Outcomes During the First Year After Discharge.

OBJECTIVE: To evaluate the effect of providing quasi-contextualized speech therapy, defined as metacognitive, compensatory, or strategy training applied to cognitive and language impairments to facilitate the performance of future real-life activities, on functional outcomes up to 1 year following traumatic brain injury (TBI). SETTING: Acute inpatient rehabilitation. PARTICIPANTS: Patients enrolled during the TBI-Practice-Based Evidence (TBI-PBE) study (n = 1760), aged 14 years or older, who sustained a severe, moderate, or complicated mild TBI, received speech therapy in acute inpatient rehabilitation at one of 9 US sites, and consented to follow-up 3 and 9 months postdischarge from inpatient rehabilitation. DESIGN: Propensity score methods applied to a database consisting of multisite, prospective, longitudinal observational data. MAIN MEASURES: Participation Assessment with Recombined Tools-Objective-17, FIM Motor and Cognitive scores, Satisfaction With Life Scale, and Patient Health Questionnaire-9. RESULTS: When at least 5% of therapy time employed quasi-contextualized treatment, participants reported better community participation during the year following discharge. Quasi-contextualized treatment was also associated with better motor and cognitive function at discharge and during the year after discharge. The benefit, however, may be dependent upon a balance of rehabilitation time that relied on contextualized treatment. CONCLUSIONS: The use of quasi-contextualized treatment may improve outcomes. Care should be taken, however, to not provide quasi-contextualized treatment at the expense of contextualized treatment.

Family Involvement in Traumatic Brain Injury Inpatient Rehabilitation: A Propensity Score Analysis of Effects on Outcomes During the First Year After Discharge.

OBJECTIVE: To evaluate the effect of family attendance at inpatient rehabilitation therapy sessions on traumatic brain injury (TBI) patient outcomes at discharge and up to 9 months postdischarge. DESIGN: Propensity score methods are applied to the TBI Practice-Based Evidence database, a database consisting of multisite, prospective, longitudinal, and observational data. SETTING: Nine inpatient rehabilitation centers in the United States. PARTICIPANTS: Patients (N=1835) admitted for first inpatient rehabilitation after an index TBI. INTERVENTION: Family attendance during therapy sessions. MAIN OUTCOME MEASURES: Participation Assessment for Recombined Tools-Objective-17 (Total scores and subdomain scores of Productivity, Out and About, and Social Relations), Functional Independence Measure, Satisfaction with Life Scale, and Patient Health Questionnaire-9. RESULTS: Participants whose families were in attendance for at least 10% of the treatment time were more out and about in their communities at 3 and 9 months postdischarge than participants whose families attended treatment less than 10% of the time. Although findings varied by propensity score method, improved functional independence in the cognitive area at 9 months was also associated with increased family attendance. CONCLUSIONS: Family involvement during inpatient rehabilitation may improve community participation and cognitive functioning up to 9 months after discharge. Rehabilitation teams should engage patients' families in the rehabilitation process to maximize outcomes.

Level of Effort and 3 Hour Rule Compliance.

OBJECTIVE: To determine if patients' level of effort (LOE) in therapy sessions during traumatic brain injury (TBI) rehabilitation modifies the effect of compliance with the 3-Hour Rule of the Centers for Medicare & Medicaid Services. DESIGN: Propensity score methodology applied to the TBI Practice-Based Evidence database, consisting of multisite, prospective, longitudinal observational data. SETTING: Acute inpatient rehabilitation facilities (IRF). PARTICIPANTS: Patients (N=1820) who received their first IRF admission for TBI in the United States and were enrolled for 3- and 9-month follow-up. MAIN OUTCOME MEASURES: Participation Assessment with Recombined Tools-Objective-17, FIM Motor and Cognitive scores, Satisfaction with Life Scale, and Patient Health Questionnaire-9. RESULTS: When the full cohort was examined, no strong main effect of compliance with the 3-Hour Rule was identified and LOE did not modify the effect of compliance with the 3-Hour Rule. In contrast, LOE had a strong positive main effect on all outcomes, except depression. When the sample was stratified by level of disability, LOE modified the effect of compliance, particularly on the outcomes of participants with less severe disability. For these patients, providing 3 hours of therapy for 50% or more of therapy days in the context of low effort resulted in poorer performance on select outcome measures at discharge and up to 9 months postdischarge compared to patients with <50% of 3-hour therapy days. CONCLUSIONS: LOE is an active ingredient in inpatient TBI rehabilitation, while compliance with the 3-Hour Rule was not found to have a substantive effect on the outcomes. The results support matching time in therapy during acute TBI rehabilitation to patients' LOE in order to optimize long-term benefits on outcomes.

Institutional Variation in Traumatic Brain Injury Acute Rehabilitation Practice.

OBJECTIVE: To describe institutional variation in traumatic brain injury (TBI) inpatient rehabilitation program characteristics and evaluate to what extent patient factors and center effects explain how TBI inpatient rehabilitation services are delivered. DESIGN: Secondary analysis of a prospective, multicenter, cohort database. SETTING: TBI inpatient rehabilitation programs. PARTICIPANTS: Patients with complicated mild, moderate, or severe TBI (N=2130). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Mean minutes; number of treatment activities; use of groups in occupational therapy, physical therapy, speech therapy, therapeutic recreation, and psychology inpatient rehabilitation sessions; and weekly hours of treatment. RESULTS: A wide variation was observed between the 10 TBI programs, including census size, referral flow, payer mix, number of dedicated beds, clinician experience, and patient characteristics. At the centers with the longest weekday therapy sessions, the average session durations were 41.5 to 52.2 minutes. At centers with the shortest weekday sessions, the average session durations were approximately 30 minutes. The centers with the highest mean total weekday hours of occupational, physical, and speech therapies delivered twice as much therapy as the lowest center. Ordinary least-squares regression modeling found that center effects explained substantially more variance than patient factors for duration of therapy sessions, number of activities administered per session, use of group therapy, and amount of psychological services provided. CONCLUSIONS: This study provides preliminary evidence that there is significant institutional variation in rehabilitation practice and that center effects play a stronger role than patient factors in determining how TBI inpatient rehabilitation is delivered.

Occupational, Physical, and Speech Therapy Treatment Activities During Inpatient Rehabilitation for Traumatic Brain Injury.

OBJECTIVE: To describe the use of occupational therapy (OT), physical therapy (PT), and speech therapy (ST) treatment activities throughout the acute rehabilitation stay of patients with traumatic brain injury. DESIGN: Multisite prospective observational cohort study. SETTING: Inpatient rehabilitation settings. PARTICIPANTS: Patients (N=2130) admitted for initial acute rehabilitation after traumatic brain injury. Patients were categorized on the basis of admission FIM cognitive scores, resulting in 5 fairly homogeneous cognitive groups. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Percentage of patients engaged in specific activities and mean time patients engaged in these activities for each 10-hour block of time for OT, PT, and ST combined. RESULTS: Therapy activities in OT, PT, and ST across all 5 cognitive groups had a primary focus on basic activities. Although advanced activities occurred in each discipline and within each cognitive group, these advanced activities occurred with fewer patients and usually only toward the end of the rehabilitation stay. CONCLUSIONS: The pattern of activities engaged in was both similar to and different from patterns seen in previous practice-based evidence studies with different rehabilitation diagnostic groups.

Predictors of Agitated Behavior During Inpatient Rehabilitation for Traumatic Brain Injury.

OBJECTIVE: To identify predictors of the severity of agitated behavior during inpatient traumatic brain injury (TBI) rehabilitation. DESIGN: Prospective, longitudinal observational study. SETTING: Inpatient rehabilitation centers. PARTICIPANTS: Consecutive patients enrolled between 2008 and 2011, admitted for inpatient rehabilitation after index TBI, who exhibited agitation during their stay (n=555, N=2130). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Daytime Agitated Behavior Scale scores. RESULTS: Infection and lower FIM cognitive scores predicted more severe agitation. The medication classes associated with more severe agitation included sodium channel antagonist anticonvulsants, second-generation antipsychotics, and gamma-aminobutyric acid-A anxiolytics/hypnotics. Medication classes associated with less severe agitation included antiasthmatics, statins, and norepinephrine-dopamine-5 hydroxytryptamine (serotonin) agonist stimulants. CONCLUSIONS: Further support is provided for the importance of careful serial monitoring of both agitation and cognition to provide early indicators of possible beneficial or adverse effects of pharmacologic interventions used for any purpose and for giving careful consideration to the effects of any intervention on underlying cognition when attempting to control agitation. Cognitive functioning was found to predict agitation, medications that have been found in previous studies to enhance cognition were associated with less agitation, and medications that can potentially suppress cognition were associated with more agitation. There could be factors other than the interventions that account for these relations. In addition, the study provides support for treatment of underlying disorders as a possible first step in management of agitation. Although the results of this study cannot be used to draw causal inferences, the associations that were found can be used to generate hypotheses about the most viable interventions that should be tested in future controlled trials.

Traumatic Brain Injury Patient, Injury, Therapy, and Ancillary Treatments Associated With Outcomes at Discharge and 9 Months Postdischarge.

OBJECTIVE: To examine associations of patient and injury characteristics, inpatient rehabilitation therapy activities, and neurotropic medications with outcomes at discharge and 9 months postdischarge for patients with traumatic brain injury (TBI). DESIGN: Prospective, longitudinal observational study. SETTING: Inpatient rehabilitation centers. PARTICIPANTS: Consecutive patients (N=2130) enrolled between 2008 and 2011, admitted for inpatient rehabilitation after an index TBI injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Rehabilitation length of stay, discharge to home, and FIM at discharge and 9 months postdischarge. RESULTS: The admission FIM cognitive score was used to create 5 relatively homogeneous subgroups for subsequent analysis of treatment outcomes. Within each subgroup, significant associations were found between outcomes and patient and injury characteristics, time spent in therapy activities, and medications used. Patient and injury characteristics explained on average 35.7% of the variation in discharge outcomes and 22.3% in 9-month outcomes. Adding time spent and level of effort in therapy activities and percentage of stay using specific medications explained approximately 20% more variation for discharge outcomes and 12.9% for 9-month outcomes. After patient, injury, and treatment characteristics were used to predict outcomes, center differences added only approximately 1.9% additional variance explained. CONCLUSIONS: At discharge, greater effort during therapy sessions, time spent in more complex therapy activities, and use of specific medications were associated with better outcomes for patients in all admission FIM cognitive subgroups. At 9 months postdischarge, similar but less pervasive associations were observed for therapy activities, but not classes of medications. Further research is warranted to examine more specific combinations of therapy activities and medications that are associated with better outcomes.

Readmission to an Acute Care Hospital During Inpatient Rehabilitation for Traumatic Brain Injury.

OBJECTIVE: To assess the incidence of, causes for, and factors associated with readmission to an acute care hospital (RTAC) during inpatient rehabilitation for traumatic brain injury (TBI). DESIGN: Prospective observational cohort. SETTING: Inpatient rehabilitation. PARTICIPANTS: Individuals with TBI admitted consecutively for inpatient rehabilitation (N=2130). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: RTAC incidence, RTAC causes, rehabilitation length of stay (RLOS), and rehabilitation discharge location. RESULTS: A total of 183 participants (9%) experienced RTAC for a total of 210 episodes. Of 183 participants, 161 patients experienced 1 RTAC episode, 17 had 2, and 5 had 3. The mean time from rehabilitation admission to first RTAC was 22±22 days. The mean duration in acute care during RTAC was 7±8 days. Eighty-four participants (46%) had ≥1 RTAC episodes for medical reasons, 102 (56%) had ≥1 RTAC episodes for surgical reasons, and 6 (3%) participants had RTAC episodes for unknown reasons. Most common surgical RTAC reasons were neurosurgical (65%), pulmonary (9%), infection (5%), and orthopedic (5%); most common medical reasons were infection (26%), neurological (23%), and cardiac (12%). Any RTAC was predicted as more likely for patients with older age, history of coronary artery disease, history of congestive heart failure, acute care diagnosis of depression, craniotomy or craniectomy during acute care, and presence of dysphagia at rehabilitation admission. RTAC was less likely for patients with higher admission FIM motor scores and education less than high school diploma. RTAC occurrence during rehabilitation was significantly associated with longer RLOS and smaller likelihood of discharge home. CONCLUSIONS: Approximately 9% of patients with TBI experienced RTAC episodes during inpatient rehabilitation for various medical and surgical reasons. This information may help inform interventions aimed at reducing interruptions in rehabilitation for RTAC. RTACs were associated with longer RLOS and discharge to an institutional setting.

Rehospitalization During 9 Months After Inpatient Rehabilitation for Traumatic Brain Injury.

OBJECTIVE: To assess the frequency of, causes for, and factors associated with acute rehospitalization during 9 months after discharge from inpatient rehabilitation for traumatic brain injury (TBI). DESIGN: Multicenter observational cohort. SETTING: Community. PARTICIPANTS: Individuals with TBI (N=1850) admitted for inpatient rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Occurrences of proxy or self-report of postrehabilitation acute care rehospitalization, as well as length of and causes for rehospitalizations. RESULTS: A total of 510 participants (28%) had experienced 775 acute rehospitalizations. All experienced 1 admission (510 participants [66%]), whereas 154 (20%) had 2 admissions, 60 (8%) had 3, 23 (3%) had 4, 27 had between 5 and 11, and 1 had 12. The most common rehospitalization causes were infection (15%), neurological (13%), neurosurgical (11%), injury (7%), psychiatric (7%), and orthopedic (7%). The mean time from rehabilitation discharge to first rehospitalization was 113 days. The mean rehospitalization duration was 6.5 days. Logistic regression analyses revealed that older age, history of seizures before injury or during acute care or rehabilitation, history of brain injuries, and non-brain injury medical severity increased the risk of rehospitalization. Injury etiology of motor vehicle collision and high motor functioning at discharge decreased rehospitalization risk. CONCLUSIONS: Approximately 28% of patients with TBI were rehospitalized within 9 months of TBI rehabilitation discharge owing to various medical and surgical reasons. Future research should evaluate whether some of these occurrences may be preventable (such as infections, injuries, and psychiatric disorders) and should evaluate the extent to which persons at risk may benefit from additional screening, surveillance, and treatment protocols.

The effect of delay in rehabilitation on outcome of severe traumatic brain injury.

BACKGROUND: Expeditious care within minutes of severe injury improves outcome and is the driving force for development of trauma care systems. Transition from hospital care to rehabilitation is an important step in recovery after trauma-related injury. We hypothesize that delay in the transition from acute care to rehabilitation adversely affects outcome and diminishes recovery after traumatic brain injury (TBI). METHODS: After institutional review board approval, the trauma registry of our regional level I pediatric trauma center was queried for all children with severe blunt TBI (initial Glasgow Coma Scale score

Rehabilitation and outcome following pediatric traumatic brain injury.

The long-term outcome for a child who has sustained a traumatic brain injury must be viewed in the context of ongoing development and maturation. Although neuronal plasticity provides the potential for neuronal reorganization in a child's brain, it is the behavioral demands of the environment that allow the child to take advantage of this potential and to maximize recovery. Pediatric rehabilitation is the setting that provides the necessary experiences for stimulating neuronal reorganization following TBI. However, neuronal reorganization has a cost to long-term development. The ultimate long-term impact of a TBI sustained in childhood depends on the child's ability to achieve developmental milestones following injury. Although injury-related and treatment-related factors are critical during the early stages of recovery, patient-related factors such as age-at-injury, developmental achievement at time of injury, maturation, and family involvement and resources impact the later stages of recovery. The process of pediatric rehabilitation following TBI is to provide an enriched, stimulating environment tailored to the needs of the child and based on real-word experiences. Early in the recovery process, pediatric rehabilitation is the setting that maximizes the potential for neuronal reorganization. Early rehabilitation also prepares the family for the child's long-term recovery and developmental needs. Involvement and training of family members early in the recovery process is critical for successful long-term outcome. Family members are the individuals best equipped to ensure treatment compliance and follow through with treatment recommendations, in maintaining treatment gains, and in generalizing treatment effects beyond the medical settings. Despite the life-long ramifications of childhood TBI, pediatric rehabilitation is the necessary step in promoting recovery and successful long-term outcome.
