"My child doesn't have a brain injury, he only has a concussion"

Summary of the Centers for Disease Control and Prevention's Self-reported Traumatic Brain Injury Survey Efforts

OBJECTIVE

Surveillance of traumatic brain injury (TBI), including concussion, in the United States has historically relied on healthcare administrative datasets, but these methods likely underestimate the true burden of TBI. The Centers for Disease Control and Prevention (CDC) has recently added TBI prevalence questions to several national surveys. The objective of this article is to summarize their recent efforts and report TBI prevalence estimates.

SETTING

Surveys.

PARTICIPANTS

Adult and youth respondents to a series of national surveys.

DESIGN

Recent nationally representative surveys with either 12-month or lifetime TBI prevalence questions were identified.

MAIN MEASURES

For each data source, survey methodology, TBI definition, question wording, and prevalence estimates were examined.

RESULTS

TBI prevalence varied depending on the question wording and data source. Overall 12-month prevalence of concussion/TBI among adults ranged from 2% to 12% while overall lifetime prevalence of concussion or TBI ranged from 19% to 29%. Overall 12-month prevalence of concussion/TBI among children and adolescents was 10% while 12-month prevalence of sports- and recreation-related concussion for youth ranged from 7% to 15%. Overall lifetime prevalence of TBI among youth ranged from 6% to 14%.

CONCLUSION

Survey data based on self-reported concussions and TBIs resulted in larger prevalence estimates than would be expected based on traditional surveillance methods. Analyses of the various surveys shows that how the questions are asked and what terminology is used can notably affect the estimates observed. Efforts can be made to optimize and standardize data collection approaches to ensure consistent measurement across settings and populations.

Comparison of self-reported lifetime concussions and mild traumatic brain injuries among adults

INTRODUCTION

The reliability of self-reported brain injury data relies on how well people interpret the questions.

OBJECTIVE

This study examines how different yet commonly used questions may impact traumatic brain injury (TBI) estimates.

METHODS

Self-report data were collected from 4,053 respondents in the summer wave of Porter Novelli's 2020 ConsumerStyles survey. Respondents were randomized to be asked about lifetime experience of either concussion or mild TBI (mTBI) and then asked follow-up questions.

RESULTS

Approximately 25.5% of respondents reported sustaining a concussion in their lifetime while 17.2% reported an mTBI. The circumstances of the injuries, such as location and mechanism of injury, were similar. A greater percentage of individuals who were asked about concussions (91.1%) reported receiving a diagnosis for their most serious injury compared to those who were asked about diagnosis of an mTBI (69.9%).

DISCUSSION

A greater percentage of respondents reported a lifetime history of concussion than mTBI. More respondents with a lifetime history of concussion reported receiving a diagnosis. These results suggest that the terminology used can impact reporting. These findings suggest that there is a meaningful difference in the understanding of the terms 'concussion' and 'mild TBI,' with people perceiving mTBI as a more serious injury.

It's a Hard Knock Life: How Kids With Mild Traumatic Brain Injuries Are Treated

OBJECTIVES

The diagnosis and treatment of mild traumatic brain injuries (mTBIs) by emergency medicine providers is greatly varied. Because of the frequency and long-term consequences associated with pediatric head injuries, it is crucial that adequate counseling is provided in acute care settings. The purpose of our study is to evaluate existing practices at Loyola University Medical Center emergency department to address inconsistencies in diagnostic or discharge practices and determine future quality improvement measures.

METHODS

A retrospective cohort study was conducted at an academic hospital emergency department of patient records from 2017 to 2020. Demographic, diagnostic, and discharge data were summarized, and Pearson χ2 tests and Fisher exact tests were performed to determine associations among patient characteristics and provider practices.

RESULTS

A total of 1160 patients met inclusion criteria for analysis. In terms of diagnostic procedure, 31.6% of providers did not uniformly use existing screening criteria, such as PECARN, to determine if CT scans were needed for mTBI evaluation. Most discharge instructions were based on a generalized template on epic (91.9%). Only a minority of providers prepared patient-specific instructions through written, verbal, or other supplemental materials. The most common formats included epic only (46.1%), epic and personalized written instructions (20.2%), and epic and verbal instructions (12.4%). Follow-up care instructions were provided to 93% of patients who received discharged instructions, mainly for primary care (96.7%), sports medicine (1.58%), neurology (0.65%), or other providers (1.11%).

CONCLUSIONS

There is a lack of consistency in the evaluation and education of mTBI in pediatric patients. There is a need for personalized discharge instructions to ensure adequate patient and parent understanding and compliance. Further studies looking at long-term outcomes in these patients would also be beneficial.

Mild traumatic brain injury and sports-related concussion

Mild traumatic brain injury (mTBI) and concussion are equivalent terms for the sequela of injury to the head that disrupts brain functioning. Various forces may be causative from seemingly innocuous bumps to the head resulting from sports-related injuries to more severe blows to the head. However, the postconcussive motor, cognitive, emotional, and psychosocial sequelae can be just as devastating and long lasting, leading to loss of independent function and safe performance of activities. Taken together, they pose a significant challenge to recovery, requiring a multifaceted dynamic rehabilitative strategy. The current systems of health care pose challenges to suboptimal management of sports-related concussion (SRC) that goes beyond the acute injury, and into the school setting, failing to be identified by school staff, and inconsistencies in communicating medical information regarding school modifications, follow-up health services, or concussion-related educational services. Children who sustain SRC at different ages face different challenges. Young children face increased vulnerability due to SRC that coincides with periods of brain motor maturation and development.

Re/producing the Pediatric Concussion Discourse in clinical rehabilitation practice

PURPOSE

In the field of pediatric concussion, little to no scholarship has examined how clinical practice is shaped by patterned ways of thinking, talking about, and coming to understand concussion and young people (or "discourses of concussion in young people"). In this paper, we examine the ways in which one such discourse, the Pediatric Concussion Discourse (PCD), shapes how young people with concussion, their parents, and clinicians can think about, act in relation to, and experience concussion.

MATERIALS AND METHODS

This critical rehabilitation research is informed by the post-structuralist theory of Michel Foucault (1926-1984), and the key concepts of power/knowledge, discourse, and the subject.

RESULTS

Circulating through clinical guidelines for the management of pediatric concussion, the PCD re/produces the expectation that young people with concussion and their parents will behave as "responsible" subjects who follow the recommendations of so-called experts without question. If recommendations are not implemented, the PCD has the potential to constitute these same groups as "nonadherent", re/producing problematic discourses of medical compliance.

CONCLUSIONS

By examining the effects of the PCD, it becomes possible to imagine how clinical practice and research might evolve in new ways that respect the knowledges and experiences of young people with concussion and their parents.Implications for RehabilitationEngaging in critical examination of clinical rehabilitative practice creates opportunity to imagine how we might approach commonly adopted clinical approaches, including the delivery of health education, differently.Implications for clinical rehabilitation practice include delivering health education in the context of supportive therapeutic relationships that respect the knowledges and experience of young people with concussion and their parents.Implications for rehabilitation research include engaging with critical scholarship within and beyond field and disciplinary boundaries, engaging in formal educational opportunities, and connecting with less formal but invaluable communities of practice.

Epidemiology of Chronic Effects of Traumatic Brain Injury

Although many patients diagnosed with traumatic brain injury (TBI), particularly mild TBI, recover from their symptoms within a few weeks, a small but meaningful subset experience symptoms that persist for months or years after injury and significantly impact quality of life for the person and their family. Factors associated with an increased likelihood of negative TBI outcomes include not only characteristics of the injury and injury mechanism, but also the person’s age, pre-injury status, comorbid conditions, environment, and propensity for resilience. In this article, as part of the Brain Trauma Blueprint: TBI State of the Science framework, we examine the epidemiology of long-term outcomes of TBI, including incidence, prevalence, and risk factors. We identify the need for increased longitudinal, global, standardized, and validated assessments on incidence, recovery, and treatments, as well as standardized assessments of the influence of genetics, race, ethnicity, sex, and environment on TBI outcomes. By identifying how epidemiological factors contribute to TBI outcomes in different groups of persons and potentially impact differential disease progression, we can guide investigators and clinicians toward more-precise patient diagnosis, along with tailored management, and improve clinical trial designs, data evaluation, and patient selection criteria.

Management of sport-related concussion in emergency departments in England: a multi-center study

OBJECTIVE

To establish the current knowledge of sport-related concussion (SRC) management of clinicians in emergency departments in the North West of England.

METHODS

A cross-sectional, multi-center study design was used and included emergency department clinicians (EDCs) across 15 centers in the North West of England. A 22-question survey was issued with questions focused on the 5th International Conference on Concussion Consensus Statement. Absolute and percentages were presented, and comparisons in knowledge of guidelines and confidence between EDCs were made using the Kruskal-Wallis test.

RESULTS

Of an estimated 300 EDCs, 111 (37%) responded. Thirty (27%) were aware of the guidelines, whilst 63 (57%) had heard of a graduated return-to-sport protocol. Physical rest was advised by 106 (95%) respondents, with 68 (61%) advising cognitive rest and 47 (42%) providing written advice. There was no difference (p > .05) in awareness of SRC guidelines or confidence between clinician grade, with most receiving no SRC training.

CONCLUSIONS

There is a lack of knowledge amongst EDCs in the North West of England in managing and providing discharge advice to patients with SRC. This is likely due to the limited awareness of guidelines and training, and therefore further education delivery on SRC management guidelines is required.

Adult attention-deficit hyperactivity disorder symptoms and psychological distress, hazardous drinking, and problem gambling: A population-based study

Recognition of ADHD in the adult population is relatively recent. Epidemiological research examining the mental health impact of ADHD in adulthood is thus limited. The objective of this study was to examine whether adult ADHD symptoms are associated with psychological distress, hazardous drinking, and problem gambling, after controlling for traumatic brain injury and sociodemographic characteristics. We analyzed data from a population-based survey administered in 2015 and 2016 to adults aged 18 years and over in Ontario, Canada (N = 3,817). Logistic regression was used to construct unadjusted and multivariable models for each of the three focal relationships. In the unadjusted models, ADHD symptoms were significantly related to psychological distress (OR = 9.3; 95% CI:6.1, 14.0) and hazardous drinking (OR = 2.1; 95% CI: 1.3, 3.4), but not to problem gambling (OR = 1.5; 0.5, 4.3). After adjustment, ADHD symptoms were significantly related to psychological distress (OR = 7.1; 95% CI: 4.6, 11.1), but not hazardous drinking (OR = 1.4; 95% CI: 0.8, 2.5) or problem gambling (OR = 0.6; 95% CI: 0.2, 2.5). This study further highlights the importance of clinicians assessing for concomitant ADHD and psychological distress in adults.

Traumatic brain injuries and problem gambling in youth: Evidence from a population-based study of secondary students in Ontario, Canada

Traumatic brain injury (TBI) is characterized by a change in brain function after an external force or sudden movement to the head. TBI is associated with risk-taking, impulsivity, psychological distress, substance abuse, and violent crime. Previous studies have also linked problem gambling to TBI, but these studies have not controlled for possible confounding variables such as mental health problems and hazardous drinking which are also linked to TBI. This study examines the relationship between problem gambling and TBI among adolescents. Data were obtained from the 2011, 2013 and 2015 cycles of the OSDUHS, a biennial cross-sectional school-based study of children in grades 7 to 12 (N = 9,198). Logistic regression was used to estimate adjusted odds ratios (AOR) in controlled and uncontrolled analyses. Adjusting for sex and grade only, problem gambling was associated with a history of TBI (AOR = 2.8). This association remained significant after adjusting for hazardous drinking and suicidality (AOR = 2.0). In addition, problem gambling had a statistically significant relationship with being male (AOR = 4.7), hazardous drinking (AOR = 4.5), and suicidality (AOR = 3.1). This study provides further data to suggest a link between TBI and problem gambling. However, research is needed on the causal relationship between these variables and the potential implications for treatment and prevention.

Self-reported concussion history among Icelandic female athletes with and without a definition of concussion

OBJECTIVE

This study examined whether Icelandic female athletes in contact sports, based their self-reported concussion history on adequate medical definitions, by assessing self-reported concussion history with and without a definition of concussion. Another aim was to examine whether currently active athletes were more knowledgeable of concussions than retired athletes.

METHODS

Participants (age = 26.9, SD = 7.1) were 508 former (34.5%) and current (65.5%) elite female athletes in soccer (41%), handball (30.6%), basketball (19.1%), ice hockey (4.5%) and combat sports (4.7%). An online questionnaire (QuestionPro) was distributed to females in contact sports (snowball sampling). Participants later came for an in-person interview where the authenticity of previous responses was confirmed. In the questionnaire, participants answered background questions and questions about concussion history. First, they reported the total number of sustained concussions without a prompt. They reported the number of sustained concussions again after reading a definition of concussion. Participants could not correct their previous answers. Pearson's Chi-square was used for group comparisons.

RESULTS

The prevalence of reported concussions increased from 40.2% to 64.8% following a definition. There was no significant difference in how many participants changed their answer when asked about sustaining SRCs before and after reading the definition based on whether the participants were still competitive or retired X ²(1) = 0.69, p = 0.41.

CONCLUSIONS

Our data suggest that understanding of concussions is inadequate among female athletes. Self-report will continue to be an essential source of clinical information and prompting with a definition can increase the reliability of self-reported concussions.

The effect of diagnostic terminology on cognitive, emotional, and post-concussive sequelae following mild brain injury

Objective: We sought to determine whether the diagnostic terms 'mild traumatic brain injury (mTBI)' and 'concussion' result in differences in perceived cognitive, emotional, and post-concussive sequelae.Method: A total of 81 healthy university students (79% female; 69% of Asian descent) were randomly assigned to one of two conditions: mTBI (n = 41), or concussion (n = 40), and were instructed to simulate on a battery of cognitive (Neuropsychological Assessment Battery - Screening Module), emotional (Beck Anxiety Inventory, Beck Depression Inventory-II), and post-concussive (Rivermead Postconcussive Symptoms Questionnaire) measures.Results: There were no significant group differences between expected cognitive, emotional, or post-concussive consequences. However, both groups received poorer scores than the normative data.Conclusions: These results suggest that diagnostic terminology does not appear to influence anticipated recovery following mild brain injury. However, the presentation of information about the injury itself may impact recovery outcomes. This study provides preliminary support for the potential negative effects that may arise as a result of providing participants with non-evidence based information about mild brain injuries.

Impact of mild traumatic brain injury understanding on intended help-seeking behaviour

Children do not always receive adequate medical attention following a mild traumatic brain injury (mTBI), despite the necessity of this treatment. Adult mTBI knowledge may be one factor that affects if a child receives medical attention, but little is known about association between mTBI knowledge and help-seeking behaviour. Participants were 212 females and 58 males, including 84 parents, with a mean age of 35.57 years (standard deviation = 10.96). A questionnaire evaluated participants' understanding of mTBI and vignettes to evaluate behavioural intentions regarding help-seeking behaviour after an mTBI. Only 40.0% of participants were able to recall an adequate number of mTBI symptoms (5+). Surprisingly, mTBI history was not associated with better mTBI knowledge, t(df, 268) = 1.29, p = .20. Similarly, knowing a close friend or family member with mTBI was not associated with higher mTBI knowledge, t(df = 268) = .81, p = .4. Further, neither mTBI symptom knowledge nor vignette child age (young = 5 years, older = 15 years) significantly predicted participants' cited intentions to perform help-seeking behaviour. Consistent with the existing research, the current study demonstrates a continued lack of mTBI knowledge in the general population. However, this may not be a factor that influences an adult's decision to take a child to hospital following mTBI. Future research should investigate the association between help-seeking intentions and actual behaviour in relation to paediatric mTBI.

What Comes First: Return to School or Return to Activity for Youth After Concussion? Maybe We Don't Have to Choose

Objectives: Return to School (RTS) and Return to Activity/Play (RTA) protocols are important in concussion management. Minimal evidence exists as to sequence and whether progression can occur simultaneously. Experts recommend that children/youth fully return to school before beginning RTA protocols. This study investigates recovery trajectories of children/youth while following RTA and RTS protocols simultaneously, with the following objectives: (1) to compare rates and patterns of progression through the stages of both protocols; (2) to evaluate symptom trajectories of youth post-concussion while progressing through stages of RTS and RTA; and (3) to propose a new model for concussion management in youth that involves the integration of Return to Activity and Return to School protocols. Methods: In a 3-year prospective-cohort study of 139 children/youth aged 5-18 years with concussive injury, self-reported symptoms using PCSS and stage of protocols were evaluated every 48 h using electronic surveys until full return to school and activity/sport were attained. Information regarding school accommodation and achievement was collected. Results: Sample mean age is 13 years, 46% male. Youth are returning to school with accommodations significantly quicker than RTA (p = 0.001). Significant negative correlations between total PCSS score and stage of RTS protocol were found at: 1-week (r = -0.376, p < 0.0001; r = -0.317, p = 0.0003), 1-month (r = -0.483, p < 0.0001; r = -0.555, p < 0.0001), and 3-months (r = -0.598, p < 0.0001; r = -0.617, p < 0.0001); indicating lower symptom scores correlated with higher guideline stages. Median full return to school time is 35 days with 21% of youth symptomatic at full return. Median return time to full sport competition is 38 days with 15% still symptomatic. Sixty-four percent of youth reported experiencing school problems during recovery and 30% at symptom resolution, with 31% reporting a drop in their grades during recovery and 18% at study completion. Conclusions: Children/youth return to school faster than they return to play in spite of the self-reported, school-related symptoms they experience while moving through the protocols. Youth can progress simultaneously through the RTS and RTA protocols during stages 1-3. Considering the numbers of youth having school difficulties post-concussion, full contact sport, stage 6, of RTA, should be delayed until full and successful reintegration back to school has been achieved. In light of the huge variability in recovery, determining how to resume participation in activities despite ongoing symptoms is still the challenge for each individual child. There is much to be learned with further research needed in this area.

New Zealand Caregiver Knowledge of Paediatric Traumatic Brain Injury

Background:

Traumatic brain injury (TBI) is common among children. However, their caregivers’ knowledge and understanding of symptoms may influence how the injury is managed.

Primary objective:

To investigate the knowledge of New Zealand (NZ) parents about TBI and concussion.

Method and procedures:

Parents (n = 205) of children aged 5–13 years completed a pen-and-paper or online survey containing questions examining their knowledge of TBI terminology, TBI symptoms and knowledge about concussion management.

Main outcomes and results:

A high proportion (61%) of parents did not think that a concussion was the same as a brain injury. Loss of consciousness (LOC) was the most endorsed symptom of TBI. However, 69% of participants were aware that TBI could occur without LOC. On average, parents correctly identified 19.5 (67.3%) of the 29 symptoms of TBI, but also identified 2.0 (11.9%) of the 17 distractor symptoms as being TBI related. Demographic factors and experience of TBI/concussion were associated with TBI symptom identification accuracy and concussion knowledge.

Conclusions:

Further education of parents is needed to ensure they recognise the signs and symptoms of concussion/mild TBI so that they can make informed decisions on how best to manage their child’s injury.

Concussion Pathophysiology and Injury Biomechanics

PURPOSE OF REVIEW

The concussion public health burden has increased alongside our knowledge of the pathophysiology of mild traumatic brain injury (mTBI). The purpose of this review is to summarize our current understanding of mTBI pathophysiology and biomechanics and how these underlying principles correlate with clinical manifestations of mTBI.

RECENT FINDINGS

Changes in post-mTBI glutamate and GABA concentrations seem to be region-specific and time-dependent. Genetic variability may predict recovery and symptom severity while gender differences appear to be associated with the neuroinflammatory response and neuroplasticity. Ongoing biomechanical research has shown a growing body of evidence in support of an "individual-specific threshold" for mTBI that varies based on individual intrinsic factors. The literature demonstrates a well-characterized timeframe for mTBI pathophysiologic changes in animal models while work in this area continues to grow in humans. Current human research shows that these underlying post-mTBI effects are multifactorial and may correlate with symptomatology and recovery. While wearable sensor technology has advanced biomechanical impact research, a definitive concussion threshold remains elusive.

Moderate to severe gambling problems and traumatic brain injury: A population-based study

Traumatic brain injury (TBI) is a common injury characterized by a change in brain function after an external blow to the head and is associated with substance abuse, psychological distress, risk-taking, and impulsivity. Convenience and clinical samples have also linked TBI to problem gambling, but have not ruled out confounding variables such as hazardous drinking and psychological distress. This study examines the relationship between TBI and moderate to severe problem gambling in a general population probability sample controlling for hazardous drinking and psychological distress. The data were obtained from a 2015-2016 cross-sectional general population telephone survey of adults ages 18+from Ontario, Canada (N = 3809). Logistic regression was used to estimate the association as adjusted odds ratios (AOR). Moderate to severe problem gambling was independently associated with a history of TBI after adjusting for potential confounders (AOR: 2.80), and had a statistically significant relationship with psychological distress (AOR = 2.74), hazardous drinking (AOR = 2.69), and lower educational levels (AOR = 0.37). This study provides further data to suggest a link between TBI and moderate to severe problem gambling; however, more research is needed to determine if there is a causal relationship or the potential implications for prevention and treatment.

Multicentre, randomised clinical trial of paediatric concussion assessment of rest and exertion (PedCARE): a study to determine when to resume physical activities following concussion in children

INTRODUCTION

Rest until symptom-free, followed by a progressive stepwise return to activities, is often prescribed in the management of paediatric concussions. Recent evidence suggests prolonged rest may hinder recovery, and early resumption of physical activity may be associated with more rapid recovery postconcussion. The primary objective is to determine whether the early reintroduction of non-contact physical activity beginning 72 hours postinjury reduces postconcussive symptoms at 2 weeks in children following an acute concussion as compared with a rest until asymptomatic protocol.

METHODS AND ANALYSIS

This study is a randomised clinical trial across three Canadian academic paediatric emergency departments. A total of 350 participants, aged 10-17.99 years, who present within 48 hours of an acute concussion, will be recruited and randomly assigned to either the study intervention protocol (resumption of physical activity 72 hours postconcussion even if experiencing symptoms) or physical rest until fully asymptomatic. Participants will document their daily physical and cognitive activities. Follow-up questionnaires will be completed at 1, 2 and 4 weeks postinjury. Compliance with the intervention will be measured using an accelerometer (24 hours/day for 14 days). Symptoms will be measured using the validated Health and Behaviour Inventory. A linear multivariable model, adjusting for site and prognostically important covariates, will be tested to determine differences between groups. The proposed protocol adheres to the RCT-CONSORT guidelines.

DISCUSSION

This trial will determine if early resumption of non-contact physical activity following concussion reduces the burden of concussion and will provide healthcare professionals with the evidence by which to recommend the best timing of reintroducing physical activities.

TRIAL REGISTRATION NUMBER

Trial identifier (Clinicaltrials.gov) NCT02893969.

Service and support needs following pediatric brain injury: perspectives of children with mild traumatic brain injury and their parents

OBJECTIVE

To provide a qualitative examination of the service and support needs of children who have had a mild traumatic brain injury (mTBI), and their parents, in order to improve clinical services.

METHODS

Semi-structured interviews were conducted with 9 children (8-12 years; M = 10.6 years, SD = 0.8) and their parents (n = 9) 29-55 days (M = 34 days; SD = 9.3) after presenting to an Australian Paediatric Emergency Department (PED) for mTBI. Children's post-concussive symptoms (PCS) were additionally measured using the Post-Concussive Symptom Inventory (PCSI). Audio recordings were transcribed, and a thematic analysis was conducted.

RESULTS

Post-injury needs were reflected in four main themes: Communication; Family Burden; Continuity of Care; and Social and Community Support. These themes reflected children's and parents' needs for information, emotional/social/community support, and follow-up care. Both the children's and parents' needs, and the extent to which they were met, appeared to be related to the severity and duration of the child's PCS.

CONCLUSIONS

Dedicated pediatric mTBI follow-up services that build on family's resources and meet their individual needs for information, emotional support, and referral may assist in optimizing post-injury outcomes.

Centers for Disease Control and Prevention Guideline on the Diagnosis and Management of Mild Traumatic Brain Injury Among Children

Importance

Mild traumatic brain injury (mTBI), or concussion, in children is a rapidly growing public health concern because epidemiologic data indicate a marked increase in the number of emergency department visits for mTBI over the past decade. However, no evidence-based clinical guidelines have been developed to date for diagnosing and managing pediatric mTBI in the United States.

Objective

To provide a guideline based on a previous systematic review of the literature to obtain and assess evidence toward developing clinical recommendations for health care professionals related to the diagnosis, prognosis, and management/treatment of pediatric mTBI.

Evidence Review

The Centers for Disease Control and Prevention (CDC) National Center for Injury Prevention and Control Board of Scientific Counselors, a federal advisory committee, established the Pediatric Mild Traumatic Brain Injury Guideline Workgroup. The workgroup drafted recommendations based on the evidence that was obtained and assessed within the systematic review, as well as related evidence, scientific principles, and expert inference. This information includes selected studies published since the evidence review was conducted that were deemed by the workgroup to be relevant to the recommendations. The dates of the initial literature search were January 1, 1990, to November 30, 2012, and the dates of the updated literature search were December 1, 2012, to July 31, 2015.

Findings

The CDC guideline includes 19 sets of recommendations on the diagnosis, prognosis, and management/treatment of pediatric mTBI that were assigned a level of obligation (ie, must, should, or may) based on confidence in the evidence. Recommendations address imaging, symptom scales, cognitive testing, and standardized assessment for diagnosis; history and risk factor assessment, monitoring, and counseling for prognosis; and patient/family education, rest, support, return to school, and symptom management for treatment.

Conclusions and Relevance

This guideline identifies the best practices for mTBI based on the current evidence; updates should be made as the body of evidence grows. In addition to the development of the guideline, CDC has created user-friendly guideline implementation materials that are concise and actionable. Evaluation of the guideline and implementation materials is crucial in understanding the influence of the recommendations.

Impact of Early Follow-Up Intervention on Parent-Reported Postconcussion Pediatric Symptoms: A Feasibility Study

OBJECTIVES

To investigate the effectiveness and feasibility of early intervention telephone counseling with parents in limiting postconcussion symptoms and impacts on children and youth.

SETTING

Recruitment occurred postdischarge from one pediatric emergency department.

PARTICIPANTS

Sixty-six parents of children aged 5 to 16 years with a diagnosis of a concussion injury.

DESIGN

A pilot, randomized controlled study compared the efficacy of telephone counseling (reviewing symptom management and return to activity with parents at 1 week and 1 month postinjury) with usual care (no formalized follow-up).

MAIN MEASURES

The Post-Concussion Symptom Inventory and the Family Burden of Injury Interview administered with parents by a blinded therapist at 3 months postinjury.

RESULTS

No significant difference between the groups at 3 months postinjury in postconcussion symptoms (P = .67) and family stress (P = .647).

CONCLUSION

The findings suggest that the early counseling intervention strategy trialed herein may not be effective for children and youth who experience significant postconcussion symptoms. Further research is needed to determine whether more intensive and integrated care would better serve children.

Pediatric Traumatic Brain Injury and Concussion

PURPOSE OF REVIEW

This article summarizes the impact and complications of mild traumatic brain injury and concussion in children and outlines the recent evidence for its assessment and early management. Useful evidence-based management strategies are provided for children who have a typical recovery following concussion as well as for those who have persistent postconcussion syndrome. Cases are used to demonstrate the commonly encountered pathologies of headache, cognitive issues, and mood disturbances following injury.

RECENT FINDINGS

A clinical risk score using risk factors for poor recovery (eg, female sex, adolescence, previous migraine, and a high degree of acute symptoms) can be used to help the clinician plan follow-up in the community. Prolonged periods of physical and cognitive rest should be avoided. Multidisciplinary treatment plans are often required in the management of persistent postconcussion syndrome.

SUMMARY

A paucity of research exists for the treatment of postconcussion syndrome. Current treatments target individual symptoms.

Factors Influencing the Underreporting of Concussion in Sports: A Qualitative Study of Minor Hockey Participants

OBJECTIVE

The present study is to identify factors contributing to underreporting of concussion in adolescent athletes.

DESIGN

Qualitative interviews.

SETTING

Participants were interviewed in an office environment.

PARTICIPANTS

Interviews were conducted with 31 minor hockey players, 10 parents, 6 coaches, 4 trainers, 2 managers, and one game official. Players were 13 to 15 year old. With selective sampling, an inductive approach of analyzing the interviews was undertaken and themes were identified and analyzed.

ASSESSMENT OF RISK FACTORS

Underreporting is a complex phenomenon. A number of risk factors related to hockey culture, players, reference others, and rules of play were assessed.

MAIN OUTCOME MEASURES

Reasons not reporting concussion is accepted in minor hockey.

RESULTS

Aspects of hockey culture such as an overemphasis on winning games and upheld misperceptions about the risks associated with concussion were identified as relevant to the underreporting of concussions. Various factors relevant to the underreporting of concussions include player's motivation to win, group membership dynamics such as a player's role as the team's "enforcer," coaches' own motivation to win to further their own opportunities in the sport, and parents' personal financial interest or alternative agenda in terms of time commitments and their child's future career prospects.

CONCLUSIONS

Our findings indicate that underreporting of concussion among those players interviewed appears to be prevalent and associated with misconceptions about injury risk, and a culture that both reinforces and encourages underreporting with tacit or overt complicity of parents and coaches. Our findings support the need to alter the culture of violence and tough play in hockey by education, rule changes, economic measures, and changes in governance of the sport. Interviewing more stakeholders and policy makers would shed light on such potential interventions.

Patient-Centered Decision Support: Formative Usability Evaluation of Integrated Clinical Decision Support With a Patient Decision Aid for Minor Head Injury in the Emergency Department

BACKGROUND

The Canadian Computed Tomography (CT) Head Rule, a clinical decision rule designed to safely reduce imaging in minor head injury, has been rigorously validated and implemented, and yet expected decreases in CT were unsuccessful. Recent work has identified empathic care as a key component in decreasing CT overuse. Health information technology can hinder the clinician-patient relationship. Patient-centered decision tools to support the clinician-patient relationship are needed to promote evidence-based decisions.

OBJECTIVE

Our objective is to formatively evaluate an electronic tool that not only helps clinicians at the bedside to determine the need for CT use based on the Canadian CT Head Rule but also promotes evidence-based conversations between patients and clinicians regarding patient-specific risk and patients' specific concerns.

METHODS

User-centered design with practice-based and participatory decision aid development was used to design, develop, and evaluate patient-centered decision support regarding CT use in minor head injury in the emergency department. User experience and user interface (UX/UI) development involved successive iterations with incremental refinement in 4 phases: (1) initial prototype development, (2) usability assessment, (3) field testing, and (4) beta testing. This qualitative approach involved input from patients, emergency care clinicians, health services researchers, designers, and clinical informaticists at every stage.

RESULTS

The Concussion or Brain Bleed app is the product of 16 successive iterative revisions in accordance with UX/UI industry design standards. This useful and usable final product integrates clinical decision support with a patient decision aid. It promotes shared use by emergency clinicians and patients at the point of care within the emergency department context. This tablet computer app facilitates evidence-based conversations regarding CT in minor head injury. It is adaptable to individual clinician practice styles. The resultant tool includes a patient injury evaluator based on the Canadian CT Head Rule and provides patient specific risks using pictographs with natural frequencies and cues for discussion about patient concerns.

CONCLUSIONS

This tool was designed to align evidence-based practices about CT in minor head injury patients. It establishes trust, empowers active participation, and addresses patient concerns and uncertainty about their condition. We hypothesize that, when implemented, the Concussion or Brain Bleed app will support-not hinder-the clinician-patient relationship, safely reduce CT use, and improve the patient experience of care.

Depression in youth recovering from concussion: Correlates and predictors

OBJECTIVES

Although depression can be a serious consequence of concussion, little is known about the factors that predict depression and concussion recovery outcomes in children. The purpose of this study was to explore the risk and possible predictors of developing significant depressive symptoms in children recovering from concussion.

METHODS

A prospective cohort study was conducted in a paediatric tertiary care clinic. Depression data were collected from 92 children using the Children's Depression Inventory-2 (CDI-2) screening tool. Correlations, t-tests and logistic regression were used to examine the associations between depression scores and demographic as well as injury-related factors.

RESULTS

Depressive symptoms were found in 22% of the children (T score on CDI-2 >65). Children with evidence of depressive symptomatology had significantly higher mean post-concussive symptom inventory (PCSI) scores in recovery (p = 0.004) than children who were not depressed. Variables of i) Sex; ii) hospital admission; iii) number of head injuries; iv) post-concussion symptom score and v) experience of prolonged symptoms were predictive of clinically significant CDI T scores, explaining 36% of the variation in the binary logistic model.

CONCLUSION

Depression is commonly reported in this subset of children. High post-concussive symptom scores and hospital admission were strong predictors of depression. Screening for depression should be standard practice in concussion management in children and youth.

Diagnostic terminology, athlete status, and history of concussion affect return to play expectations and anticipated symptoms following mild traumatic brain injury

"Mild traumatic brain injury" (mTBI) and "concussion" are terms often used interchangeably. However, "mTBI" is frequently seen as representing a broader injury that encompasses the construct of "concussion," which often conveys transience or decreased severity. The present study examined the influence of varying diagnostic terminology on acute injury expectations in an undergraduate population (N = 105). Participants were presented with an mTBI vignette and were randomly assigned to one of two conditions in which the term "mTBI" or "concussion" was used to describe the injury. There were no significant differences between the two conditions on anxiety, symptomatology, timeline, or consequence scales. However, participants in the "mTBI" group allocated more days to return to play than participants in the "concussion" group, suggesting that terminology has an effect on perceptions of the severity of the injury. Varsity athletes allocated fewer days to return to play than nonathletes. Individuals with a history of concussion, both athletes and nonathletes, indicated fewer days to return to play, but greater symptomatology than individuals with no history of concussion. Clinicians should consider the influence of diagnostic terminology, athletic background, and history of concussion on perceptions of the severity of an injury because expectations can influence injury outcomes and compliance in a recovery process.

Expanding Advocacy for Head Trauma Vision Research Funding

In this article, we explore the roles of media, research, and advocacy in education and research funding. All three have played critical roles in advancing our understanding of eye, vision, and brain injuries in sports and in the military.

Concussion and its management: What do parents know?

OBJECTIVES

To determine the sensitivity of parental suspicion of concussion relative to paediatric emergency physicians in children who presented to an emergency department (ED) with a head injury. A secondary objective was to examine the variables associated with parental suspicion of concussion concordant with that of a physician.

METHODS

Parents of children five to 18 years of age presenting to an urban paediatric ED with a nonstructural head injury completed a 24-item questionnaire.

RESULTS

Of the 577 eligible parents, 495 (85.8%) consented to participate. The sensitivity of parental suspicion for concussion was 40.0% (95% CI 33.2% to 47.2%), while the specificity was 58.3% (95% CI 52.4% to 64.0%). The variable of child age ≥10 years was associated with an increased odds (OR 3.0) of a parental suspicion of concussion concordant with that of a physician; parent age, parent sex, mechanism of head injury and history of concussion in the child were not. Although 453 (91.5%) parents would stop activity if they believed their child sustained a concussion, only 159 (32.1%) were familiar with return-to-play guidelines.

CONCLUSIONS

Parents often did not suspect a concussion when it was ultimately diagnosed by a paediatric emergency physician, although they were more likely to do so in older children. Only approximately one-third were aware of return-to-play guidelines. To enhance the potential for parent-driven advocacy in the recognition and management of concussion, these data support the need for increased parental education on this injury.

Substance Use and Related Harms Among Adolescents With and Without Traumatic Brain Injury

OBJECTIVE

The relationship between self-reported lifetime traumatic brain injury (TBI) and drug and alcohol use and associated harms was examined using an epidemiological sample of Canadian adolescents.

SETTINGS AND DESIGN

Data were derived from a 2011 population-based cross-sectional school survey, which included 6383 Ontario 9th-12th graders who self-completed anonymous self-administered questionnaires in classrooms. Traumatic brain injury was defined as loss of consciousness for at least 5 minutes or a minimum 1-night hospital stay due to symptoms.

RESULTS

Relative to high schoolers without a history of TBI, those who acknowledged having a TBI in their lifetime had odds 2 times greater for binge drinking (5+ drinks per occasion in the past 4 weeks), 2.5 times greater for daily cigarette smoking, 2.9 times greater for nonmedical use of prescription drugs, and 2.7 times greater for consuming illegal drug in the past 12 months. Adolescents with a history of TBI had greater odds for experiencing hazardous/harmful drinking (adjusted odds ratio [aOR] = 2.3), cannabis problems (aOR = 2.4), and drug problems (aOR = 2.1), compared with adolescents who were never injured.

CONCLUSION

There are strong and demographically stable associations between TBI and substance use. These associations may not only increase the odds of injury but impair the quality of postinjury recovery.

Aggression, Violence and Injury in Minor League Ice Hockey: Avenues for Prevention of Injury

Background

In North America, more than 800,000 youth are registered in organized ice hockey leagues. Despite the many benefits of involvement, young players are at significant risk for injury. Body-checking and aggressive play are associated with high frequency of game-related injury including concussion. We conducted a qualitative study to understand why youth ice hockey players engage in aggressive, injury-prone behaviours on the ice.

Methods

Semi-structured interviews were conducted with 61 minor ice hockey participants, including male and female players, parents, coaches, trainers, managers and a game official. Players were aged 13–15 playing on competitive body checking teams or on non-body checking teams. Interviews were manually transcribed, coded and analyzed for themes relating to aggressive play in minor ice hockey.

Results

Parents, coaches, teammates and the media exert a large influence on player behavior. Aggressive behavior is often reinforced by the player’s social environment and justified by players to demonstrate loyalty to teammates and especially injured teammates by seeking revenge particularly in competitive, body-checking leagues. Among female and male players in non-body checking organizations, aggressive play is not reinforced by the social environment. These findings are discussed within the framework of social identity theory and social learning theory, in order to understand players’ need to seek revenge and how the social environment reinforces aggressive behaviors.

Conclusion

This study provides a better understanding of the players’ motivations and environmental influences around aggressive and violent play which may be conducive to injury. The findings can be used to help design interventions aimed at reducing aggression and related injuries sustained during ice hockey and sports with similar cultures and rules.

Risk of suicide after a concussion

BACKGROUND

Head injuries have been associated with subsequent suicide among military personnel, but outcomes after a concussion in the community are uncertain. We assessed the long-term risk of suicide after concussions occurring on weekends or weekdays in the community.

METHODS

We performed a longitudinal cohort analysis of adults with diagnosis of a concussion in Ontario, Canada, from Apr. 1, 1992, to Mar. 31, 2012 (a 20-yr period), excluding severe cases that resulted in hospital admission. The primary outcome was the long-term risk of suicide after a weekend or weekday concussion.

RESULTS

We identified 235,110 patients with a concussion. Their mean age was 41 years, 52% were men, and most (86%) lived in an urban location. A total of 667 subsequent suicides occurred over a median follow-up of 9.3 years, equivalent to 31 deaths per 100,000 patients annually or 3 times the population norm. Weekend concussions were associated with a one-third further increased risk of suicide compared with weekday concussions (relative risk 1.36, 95% confidence interval 1.14-1.64). The increased risk applied regardless of patients' demographic characteristics, was independent of past psychiatric conditions, became accentuated with time and exceeded the risk among military personnel. Half of these patients had visited a physician in the last week of life.

INTERPRETATION

Adults with a diagnosis of concussion had an increased long-term risk of suicide, particularly after concussions on weekends. Greater attention to the long-term care of patients after a concussion in the community might save lives because deaths from suicide can be prevented.

Understanding Overuse of Computed Tomography for Minor Head Injury in the Emergency Department: A Triangulated Qualitative Study

BACKGROUND

Overuse of computed tomography (CT) for minor head injury continues despite developed and rigorously validated clinical decision rules like the Canadian CT Head Rule (CCHR). Adherence to this sensitive and specific rule could decrease the number of CT scans performed in minor head injury by 35%. But in practice, the CCHR has failed to reduce testing, despite its accurate performance.

OBJECTIVES

The objective was to identify nonclinical, human factors that promote or inhibit the appropriate use of CT in patients presenting to the emergency department (ED) with minor head injury.

METHODS

This was a qualitative study in three phases, each with interview guides developed by a multidisciplinary team. Subjects were recruited from patients treated and released with minor head injuries and providers in an urban academic ED and a satellite community ED. Focus groups of patients (four groups, 22 subjects total) and providers (three groups, 22 subjects total) were conducted until thematic saturation was reached. The findings from the focus groups were triangulated with a cognitive task analysis, including direct observation in the ED (>150 hours), and individual semistructured interviews using the critical decision method with four senior physician subject matter experts. These experts are recognized by their peers for their skill in safely minimizing testing while maintaining patient safety and engagement. Focus groups and interviews were audio recorded and notes were taken by two independent note takers. Notes were entered into ATLAS.ti and analyzed using the constant comparative method of grounded theory, an iterative coding process to determine themes. Data were double-coded and examined for discrepancies to establish consensus.

RESULTS

Five core domains emerged from the analysis: establishing trust, anxiety (patient and provider), constraints related to ED practice, the influence of others, and patient expectations. Key themes within these domains included patient engagement, provider confidence and experience, ability to identify and manage patient anxiety, time constraints, concussion knowledge gap, influence of health care providers, and patient expectations to get a CT.

CONCLUSIONS

Despite high-quality evidence informing use of CT in minor head injury, multiple factors influence the decision to obtain CT in practice. Identifying and disseminating approaches and designing systems that help clinicians establish trust and manage uncertainty within the ED context could optimize CT use in minor head injury.

The association between traumatic brain injury and ADHD in a Canadian adult sample

OBJECTIVE

This study describes the association between lifetime traumatic brain injury (TBI) and attention deficit and hyperactivity disorder (ADHD) among Canadian adults.

METHOD

A cross-sectional sample of 3993 Ontario adults aged 18 or older were surveyed by Computer Assisted Telephone Interviewing (CATI) throughout 2011 and 2012 as part of the CAMH Monitor, a rolling survey assessing the health, mental health and substance use of Ontario adults. TBI was defined as trauma to the head that resulted in loss of consciousness for at least five minutes or overnight hospitalization. ADHD was measured by the 6-item ASRS screener for adult ADHD, and self-reported history of diagnosed ADHD.

RESULTS

Among adults with a history of TBI, 6.6% (95% CI: 4.7, 9.4) screened ADHD positive, and 5.9% (95% CI: 3.6, 9.5) reported having been diagnosed with ADHD in their lifetime. Adults with lifetime TBI had significantly greater odds of scoring positive on the ADHD/ASRS screen (OR = 2.49, 95% CI: 1.54, 4.04), and of reporting a history of diagnosed ADHD (OR = 2.64, 95% CI: 1.40, 4.98) than without TBI, when holding values of sex, age, and education constant.

CONCLUSION

Significant positive associations between lifetime TBI and both current and past ADHD were observed among adults in this population. More research to understand these associations, and their significance for the etiology and management of TBI and ADHD, is needed.

Energy Drinks, Alcohol, Sports and Traumatic Brain Injuries among Adolescents

Importance

The high prevalence of traumatic brain injuries (TBI) among adolescents has brought much focus to this area in recent years. Sports injuries have been identified as a main mechanism. Although energy drinks, including those mixed with alcohol, are often used by young athletes and other adolescents they have not been examined in relation to TBI.

Objective

We report on the prevalence of adolescent TBI and its associations with energy drinks, alcohol and energy drink mixed in with alcohol consumption.

Design, Settings and Participants

Data were derived from the Centre for Addiction and Mental Health’s 2013 Ontario Student Drug Use and Health Survey (OSDUHS). This population-based cross-sectional school survey included 10,272 7^th to 12^th graders (ages 11–20) who completed anonymous self-administered questionnaires in classrooms.

Main Outcome Measures

Mild to severe TBI were defined as those resulting in a loss of consciousness for at least five minutes, or being hospitalized for at least one night. Mechanism of TBI, prevalence estimates of TBI, and odds of energy drink consumption, alcohol use, and consumption of energy drinks mixed with alcohol are assessed.

Results

Among all students, 22.4% (95% CI: 20.7, 24.1) reported a history of TBI. Sports injuries remain the main mechanism of a recent (past year) TBI (45.5%, 95% CI: 41.0, 50.1). Multinomial logistic regression showed that relative to adolescents who never sustained a TBI, the odds of sustaining a recent TBI were greater for those consuming alcohol, energy drinks, and energy drinks mixed in with alcohol than abstainers. Odds ratios were higher for these behaviors among students who sustained a recent TBI than those who sustained a former TBI (lifetime but not past 12 months). Relative to recent TBI due to other causes of injury, adolescents who sustained a recent TBI while playing sports had higher odds of recent energy drinks consumption than abstainers.

Conclusions and Relevance

TBI remains a disabling and common condition among adolescents and the consumption of alcohol, energy drinks, and alcohol mixed with energy drinks further increase the odds of TBI among adolescents. These associations warrant further investigation.

A Balanced Protocol for Return to School for Children and Youth Following Concussive Injury

BACKGROUND

Few protocols exist for returning children/youth to school after concussion. Childhood concussion can significantly affect school performance, which is vital to social development, academic learning, and preparation for future roles. The goal of this knowledge translation research was to develop evidence based materials to inform physicians about pediatric concussion.

METHODS

The Return to School (RTS) concussion protocol was developed following the National Institute for Health and Care Excellence procedures.

RESULTS

Based on a scoping review, and stakeholder opinions, an RTS protocol was developed for children/youth. This unique protocol focuses on school adaptation in 4 main areas: (a) timetable/attendance, (b) curriculum, (c) environmental modifications, and (d) activity modifications.

CONCLUSION

A balance of cognitive rest and timely return to school need to be considered for returning any student to school after a concussion. Implementation of these new recommendations may be an important tool in prevention of prolonged absence from school and academic failure while supporting brain recovery.

Misconceptions and Misattributions About Traumatic Brain Injury: An Integrated Conceptual Framework

The objective of the present narrative review was to provide a conceptual framework to address common misconceptions in the field of traumatic brain injury (TBI) and enhance clinical and research practices. This framework is based on review of the literature on TBI knowledge and beliefs. The comprehensive search of the literature included seminal and current texts as well as relevant articles on TBI knowledge and education, misconceptions, and misattributions. Reviewed materials ranged from 1970 to 2013 and were obtained from PubMed and PubMed Central online research databases. Research findings from the reviewed literature were integrated with existing social and cognitive psychological concepts to develop a framework that includes: (1) the identification antecedents of TBI-related misconceptions and misattribution; (2) understanding of how inaccurate beliefs form and persist as the result of pre- and postinjury cognitive operations such as informational cascades and attribution biases; and (3) a discussion of ways in which these beliefs can result in consequences in all domains of a survivor's life, including physical and mental health, stigma, and discrimination. This framework is intended to serve as a first stage of development of a model that will improve treatment endeavors and service delivery to individuals with TBI and their families.

The diagnosis of concussion in a pediatric emergency department

OBJECTIVES

To compare the proportion of children diagnosed with a concussion by pediatric emergency physicians vs the proportion who met criteria for this injury as recommended by Zurich Fourth International Conference on Concussion consensus statement and to determine clinical variables associated with a physician diagnosis of a concussion.

STUDY DESIGN

This was a prospective, cross-sectional study conducted at a tertiary care pediatric emergency department. We enrolled children ages 5 through 17 who presented with a head injury and collected data on demographics, mechanism of injury, head injury-related symptoms/signs, physician diagnosis, and discharge advice.

RESULTS

We identified 495 children whose mean age was 10.1 years (SD 3.4 years); 308 (62.2%) were male. Emergency physicians diagnosed concussion in 200 (40.4%; 95% CI 36.1, 44.7) children, and 443 (89.5%; 95% CI 86.8, 92.2) met criteria for concussion in accordance with the Zurich consensus statement (P<.0001). Age≥10 years (OR 1.8), presentation≥1 day after injury (OR 2.4), injury from collision sports (OR 5.6), and symptoms of headache (OR 2.2) or amnesia (OR 3.4) were the variables significantly associated with an emergency physician's diagnosis of concussion.

CONCLUSIONS

Pediatric emergency physicians diagnosed concussion less often relative to international consensus-based guidelines and used a limited number of variables to make this diagnosis compared with current recommendations. Thus, pediatric emergency physicians may be missing cases of concussion and the corresponding opportunity to provide critical advice for cognitive and physical management.

Canadian pediatric emergency physician knowledge of concussion diagnosis and initial management

Introduction

The diagnosis of concussion is a critical step in the appropriate management of patients following minor head trauma. The authors hypothesized that wide practice variation exists among pediatric emergency medicine physicians in the application of physical and cognitive rest recommendations following an acute concussion.

Methods

The authors developed a 35-item questionnaire incorporating case vignettes to examine pediatric emergency physician knowledge of concussion diagnosis, understanding of initial management using return-to-play/school/work guidelines, use of existing concussion protocols, and perceived barriers to protocol use. Using a modified Dillman technique, the authors distributed an online survey to members of Pediatric Emergency Research Canada, a national association of pediatric emergency physicians.

Results

Of 176 potential participants, 115 (65%) responded to the questionnaire, 89% (95% confidence interval [CI]: 0.81, 0.93) of whom reported having diagnosed 20 or more concussions annually. Although 90% (95% CI: 0.83, 0.94) of respondents adequately diagnosed concussion, only 64% (95% CI: 0.54, 0.72) correctly applied graduated return-to-play guidelines. Cognitive rest recommendations were also frequently limited: 40% (95% CI: 0.31, 0.49) did not recommend school absence, 30% (95% CI: 0.22, 0.39) did not recommend schoolwork reduction, and 35% (95% CI: 0.27, 0.45) did not recommend limiting screen time. Eighty percent (95% CI: 0.72, 0.87) of respondents reported having used guidelines frequently or always to guide clinical decisions regarding concussion.

Conclusion

Despite a proficiency in the diagnosis of concussion, pediatric emergency physicians exhibit wide variation in recommending the graduated return to play and cognitive rest following concussion.

Assessment of veteran and caregiver knowledge about mild traumatic brain injury in a VA Medical Center

OBJECTIVE

To examine the accuracy of knowledge about mild traumatic brain injury (TBI) of veterans and their friends/family members.

SETTING

VA Medical Center.

PARTICIPANTS

One hundred veterans and 50 of their friends/family members.

DESIGN

Cross-sectional survey.

MAIN MEASURES

A 60-item questionnaire was created by drawing both from the Neurobehavioral Symptom Inventory and from a brain injury knowledge survey developed for use with the general public.

RESULTS

Both groups were equally able to identify true mild TBI items, but both also endorsed numerous items not typical of a mild injury. Self-reported prior TBI and receipt of TBI education were unrelated to the level of knowledge. For both groups, knowing another individual with TBI was unrelated to other aspects of mild TBI knowledge. Only 1 in 5 veterans endorsed receiving brain injury education while in the military.

CONCLUSION

Results of this study may assist in the development of targeted TBI educational interventions for veterans and their friends/family members within the Veterans Affairs system. Ultimately, increased knowledge about mild TBI improves the likelihood that veterans receive care congruent with their needs and may potentially improve outcomes for those with mild TBI.
