The diagnosing and treatment of concussions.

Mild traumatic brain injury, such as concussion, was once considered self-resolving. However, over the past decade, increased understanding of the short- and long-term impact has led to new guidelines for active management. In this review, we summarise recent findings, covering diagnostic criteria, and management for early and persistent symptoms. Many of the postconcussive symptoms can be treated and an individualised approach from a biopsychosocial perspective is recommended. Overall, the new knowledge will significantly impact patient care and future research.

The Evaluation and Management of Concussion to Optimize Safe Recovery.

Concussion is a mild traumatic brain injury causing temporary neurologic dysfunction. Symptoms following concussion are variable and generally are expected to resolve within about 1 month, but some patients experience persistent and prolonged symptoms. An early return to safe, symptom-limited activity is now favored, using targeted rehabilitation and treatments. Accommodations may be needed to facilitate return-to-school and work following concussion. Athletes should not be cleared for a full return to sport until they have recovered from a concussion and completed a return-to-play progression, in addition to returning to work/school fully.

National Athletic Trainers' Association Bridge Statement: Management of Sport-Related Concussion.

OBJECTIVE: To provide athletic trainers and team physicians with updated recommendations to the 2014 National Athletic Trainers' Association (NATA) concussion position statement regarding concussion management, specifically in the areas of education, assessment, prognostic factors, mental health, return to academics, physical activity, rest, treatment, and return to sport. BACKGROUND: Athletic trainers have benefited from the 2 previous NATA position statements on concussion management, and although the most recent NATA position statement is a decade old, knowledge gains in the medical literature warrant updating several (but not all) recommendations. Furthermore, in various areas of the body of literature, current evidence now exists to address items not adequately addressed in the 2014 statement, necessitating the new recommendations. This document therefore serves as a bridge from the 2014 position statement to the current state of concussion evidence, recommendations from other organizations, and discrepancies between policy and practice. RECOMMENDATIONS: These recommendations are intended to update the state of the evidence concerning the management of patients with sport-related concussion, specifically in the areas of education; assessment advances; prognostic recovery indicators; mental health considerations; academic considerations; and exercise, activity, and rehabilitation management strategies.

Patient-centered mild traumatic brain injury interventions in the emergency department.

INTRODUCTION: Traumatic brain injury (TBI) results in 2.5 million emergency department (ED) visits per year in the US, with mild traumatic brain injury (mTBI) accounting for 90% of cases. There is considerable evidence that many experience chronic symptoms months to years later. This population is rarely represented in interventional studies. Management of adult mTBI in the ED has remained unchanged, without consensus of therapeutic options. The aim of this review was to synthesize existing literature of patient-centered ED treatments for adults who sustain an mTBI, and to identify practices that may offer promise. METHODS: A systematic review was conducted using the PubMed and Cochrane databases, while following PRISMA guidelines. Studies describing pediatric patients, moderate to severe TBI, or interventions outside the ED were excluded. Two reviewers independently performed title and abstract screening. A third blinded reviewer resolved discrepancies. The Mixed Methods Appraisal Tool (MMAT) was employed to assess the methodological quality of the studies. RESULTS: Our search strategy generated 1002 unique titles. 95 articles were selected for full-text screening. The 26 articles chosen for full analysis were grouped into one of the following intervention categories: (1) predictive models for Post-Concussion Syndrome (PCS), (2) discharge instructions, (3) pharmaceutical treatment, (4) clinical protocols, and (5) functional assessment. Studies that implemented a predictive PCS model successfully identified patients at highest risk for PCS. Trials implementing discharge related interventions found the use of video discharge instructions, encouragement of daily light exercise or bed rest, and text messaging did not significantly reduce mTBI symptoms. The use of electronic clinical practice guidelines (eCPG) and longer leaves of absence from work following injury reduced symptoms. Ondansetron was shown to reduce nausea in mTBI patients. Studies implementing ED Observation Units found significant declines in inpatient admissions and length of hospital stay. The use of tablet-based tasks was found to be superior to many standard cognitive assessments. CONCLUSION: Validated instruments are available to aid clinicians in identifying patients at risk for PCS or serious cognitive impairment. EDOU management and evidence-based modifications to discharge instructions may improve mTBI outcomes. Additional research is needed to establish the therapeutic value of medications and lifestyle changes for the treatment of mTBI in the ED.

Assessment and management of sport-related concussion in general practice.

BACKGROUND: Sport-related concussion (SRC) is a traumatic brain injury that occurs during sport or exercise activity. SRC is a growing health concern in Australia, with increasing public awareness and presentations to general practitioners being increasingly common. OBJECTIVE: This article will focus on the assessment and management of SRC in general practice, including guidance for returning patients to sport. Concussion prevention, potential long-term complications, and the decision-making process regarding retirement from sport are beyond the scope of this article. DISCUSSION: Recognising concussion can be difficult, as clinical symptoms and signs of SRC can evolve over a period of hours to days. General practitioners should be aware of the range of clinical concussion presentations. The key principles of management include relative rest, followed by a graduated return to cognitive and physical activity. Involvement of a multidisciplinary team can improve symptoms for those patients whose concussion symptoms are prolonged.

mTBI evaluation, management, and referral to allied healthcare: practices of first-line healthcare professionals.

PRIMARY OBJECTIVE: To gain an understanding of current evaluation practices, post-injury recommendations, and referrals to allied healthcare professions (AHP) by first-line healthcare professionals (FHPs) providing care for people with mild traumatic brain injury (mTBI). RESEARCH DESIGN: Survey study. METHODS AND PROCEDURES: Physicians, physician assistants, nurse practitioners, nurses, and athletic trainers (n = 126) completed an online survey, including Likert scale and free response question relating to mTBI evaluation, management, and referral practices. MAIN OUTCOMES AND RESULTS: FHPs surveyed reported being confident in their ability to evaluate patients with suspected mTBI, relying most heavily on patient-reported symptoms and physical signs as methods of evaluation. Most FHPs reported making recommendations to compensate for the symptoms experienced following mTBI diagnosis. In contrast, FHPs expressed challenges in the evaluation and management of symptoms associated with mTBI along with limited knowledge of and referrals to AHPs. CONCLUSIONS: Overall, FHPs feel confident in the diagnosis of mTBI but experience assessment and management challenges. AHPs are underutilized on mTBI management teams calling for a need for multidisciplinary collaboration on research, education, and rehabilitation efforts to optimally care for people experiencing mTBI symptoms.

Optimizing Concussion Care Seeking: Connecting Care-Seeking Behaviors and Neurophysiological States Through Blood Biomarkers.

BACKGROUND: Timely and appropriate medical care after concussion presents a difficult public health problem. Concussion identification and treatment rely heavily on self-report, but more than half of concussions go unreported or are reported after a delay. If incomplete self-report increases exposure to harm, blood biomarkers may objectively indicate this neurobiological dysfunction. PURPOSE/HYPOTHESIS: The purpose of this study was to compare postconcussion biomarker levels between individuals with different previous concussion diagnosis statuses and care-seeking statuses. It was hypothesized that individuals with undiagnosed concussions and poorer care seeking would show altered biomarker profiles. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Blood samples were collected from 287 military academy cadets and collegiate athletes diagnosed with concussion in the Advanced Research Core of the Concussion Assessment, Research and Education Consortium. The authors extracted each participant's self-reported previous concussion diagnosis status (no history, all diagnosed, ≥1 undiagnosed) and whether they had delayed or immediate symptom onset, symptom reporting, and removal from activity after the incident concussion. The authors compared the following blood biomarkers associated with neural injury between previous concussion diagnosis status groups and care-seeking groups: glial fibrillary acidic protein, ubiquitin c-terminal hydrolase-L1 (UCH-L1), neurofilament light chain (NF-L), and tau protein, captured at baseline, 24 to 48 hours, asymptomatic, and 7 days after unrestricted return to activity using tests of parallel profiles. RESULTS: The undiagnosed previous concussion group (n = 21) had higher levels of NF-L at 24- to 48-hour and asymptomatic time points relative to all diagnosed (n = 72) or no previous concussion (n = 194) groups. For those with delayed removal from activity (n = 127), UCH-L1 was lower at 7 days after return to activity than that for athletes immediately removed from activity (n = 131). No other biomarker differences were observed. CONCLUSION: Individuals with previous undiagnosed concussions or delayed removal from activity showed some different biomarker levels after concussion and after clinical recovery, despite a lack of baseline differences. This may indicate that poorer care seeking can create neurobiological differences in the concussed brain.

Nutritional Considerations of Irish Performance Dietitians and Nutritionists in Concussion Injury Management.

Sport-related concussion incidence has increased in many team-based sports, such as rugby, Gaelic (camogie, hurling, football), and hockey. Concussion disrupts athletes' brain function, causing an "energy crisis" that requires energy and nutrient support to restore function and heal. Performance dietitians and nutritionists play a role in supporting athletes' post-injury nutritional demands. This study aimed to investigate Irish performance dietitians' and nutritionists' knowledge and implementation of nutritional strategies to manage and support athletes' recovery following concussion. In-depth, semi-structured interviews were conducted with seventeen (n = 17) Irish performance dietitians and nutritionists recruited from the Sport and Exercise Nutrition register and other sporting body networks across Ireland. Participants practised or had practised with amateur and/or professional athletes within the last ten years. All interviews and their transcripts were thematically analysed to extract relevant insights. These data provided valuable insights revealing performance dietitians and nutritionists: (1) their awareness of concussion events and (2) their use of nutritional supports for concussion management. Furthermore, the research highlighted their implementation of 'novel nutritional protocols' specifically designed to support and manage athletes' concussion recovery. There was a clear contrast between participants who had an awareness and knowledge of the importance of nutrition for brain recovery after sport-related concussion(s) and those who did not. Participants presenting with a practical understanding mentioned re-emphasising certain foods and supplements they were already recommending to athletes in the event of a concussion. Performance dietitians and nutritionists were keeping up to date with nutrition research on concussions, but limited evidence has prevented them from implementing protocols in practice. Meanwhile, participants mentioned trialling/recommending nutritional protocols, such as carbohydrate reloading, reducing omega-6 intake, and acutely supplementing creatine, omega-3 fish oils high in Docosahexaenoic acid, and probiotics to support brain healing. Performance dietitians' and nutritionists' use of nutrition protocols with athletes following concussion was linked to their knowledge and the limited scientific evidence available. Nutrition implementation, therefore, may be overlooked or implemented with uncertainty, which could negatively affect athletes' recovery following sports-related concussions.

Concussion Care in Teenage Athletes.

Concussion is a form of traumatic brain injury that occurs commonly in pediatric patients. One group at higher risk for concussion is adolescent and teenage athletes. Athletes may sustain one or more concussions throughout their athletic careers, and these injuries may lead to significant morbidities for children. Although most concussion symptoms will resolve in less than 1 month, there is a subset of patients for whom symptoms may persist. Given the increased interest in preventing long-term sequelae related to concussion, legislation has been passed across the United States that aims to identify concussion promptly and remove participants from play after an injury has occurred. Care and treatment for concussion is evolving, with newer recommendations stating that complete or extreme rest may be unnecessary during the recovery period. Pediatricians and those who interact with young athletes should be aware of the guidelines surrounding return-to-play and return-to-learn in their geographic area of practice.

Systematic Review and Critical Appraisal of Role Definition and Responsibility Within the Concussion Management Team for Secondary Schools.

ABSTRACT: BACKGROUND: Sports- and recreation-related concussions impact the cognitive function of secondary school students during the recovery process. They can cause symptoms such as headache, difficulty concentrating, and memory impairment, which pose a challenge for students during the return to learn (RTL) after injury. Concussion management teams (CMTs) assist the student in managing symptoms and develop an individualized RTL process; however, the ideal composition of professionals involved in the CMT has not been fully evaluated. METHODS: A systematic review was conducted to assess current research on CMTs in secondary schools. A search of the databases CINAHL, MEDLINE, and PsycINFO was conducted using the search terms "concussion management team" AND "school" OR "return to learn." RESULTS: Twenty-four articles were included for review. The CMT structure was highly variable in all studies. Identified themes from the literature were confusion of role definition and function, and communication gaps among interdisciplinary team members. Half of the articles viewed the school nurse as the leader in coordinating the CMT and RTL process. CONCLUSION: Evidence from this review suggests further consensus in this field is needed to clarify the school nurse's role and standardize the CMT structure.

Acute Sport-Related Concussion Management and Return to Sport Time in High School Athletes.

BACKGROUND: The current evidence for acute management practices of sport-related concussion (SRC) is often limited to in-clinic visits, with limited studies identifying professionals in early SRC care and the association with prolonged recovery outcomes. PURPOSE: To describe acute SRC management practices (ie, the personnel in the initial evaluations, removal from activity) and test the association with prolonged return to sport (RTS) time. STUDY DESIGN: Descriptive epidemiology study. METHODS: We conducted a retrospective cohort study of 17,081 high school SRCs accrued between the 2015-2016 and 2020-2021 academic years. We reported acute management practices and RTS time as frequencies stratified by sex, sport, and event type and compared athletic trainer (AT) access in initial evaluation with chi-square tests (P < .05). Separate logistic regressions estimated odds ratios (ORs) and 95% CIs for removal from activity and prolonged RTS >21 days by acute management practices. RESULTS: Most SRCs (n = 12,311 [72.1%]) had complete initial evaluation by an AT. Boys had an AT evaluation in 75.5% (n = 2860/3787) of practice-related and 74.8% (n = 5551/7423) of competition-related events. Girls had an AT evaluation in 61.3% (n = 1294/2110) of practice-related and 69.3% (n = 2606/3761) of competition-related events. In sex-comparable sports (n = 6501), there was no difference between boys (n = 1654/2455 [67.4%]) and girls (n = 2779/4046 [68.7%]) having an AT involved in the first evaluation (χ2 = 1.21; P = .27). Notably, 25.3% of girls' SRCs were evaluated by a coach alone, and we observed differences in personnel in initial evaluations by sport. The odds of immediate removal were higher when an AT made the initial evaluation (OR, 2.8 [95% CI, 2.54-3.08]). The odds of prolonged RTS >21 days was lower for those with an AT in the initial evaluation (OR, 0.74 [95% CI, 0.65-0.84]) adjusting for significant factors from univariate analyses, boys relative to girls (OR, 0.85 [95% CI, 0.76-0.96]), specialty care relative to PCP (OR, 2.16 [95% CI, 1.90-2.46]), specialty care relative to urgent or ready care (OR, 0.99 [95% CI, 0.82-1.22]) concussion history (OR, 1.41 [95% CI, 1.22-1.63]), and removal from activity (OR, 0.90 [95% CI, 0.78-1.05]). CONCLUSION: This study found variability in personnel involved in initial SRC evaluations, with higher percentages of athletes with SRCs having ATs make the initial evaluation during competitive events. There was no association between sex and AT involvement in comparable sports. There was an association between prolonged RTS and AT involvement, sex, concussion history, and location of follow-up care.

Reduced Concussion Symptom Burden in Early Adolescent Athletes Using a Head-Neck Cooling Device.

OBJECTIVE: To determine whether an investigational head-neck cooling device, Pro2cool, can better reduce symptom severity compared with standard postconcussion care in early adolescent athletes after a sports-related concussion. DESIGN: Prospective, longitudinal, randomized trial design conducted over a 28-day period. SETTING: Six pediatric medical centers in Ohio and Michigan. PARTICIPANTS: The study enrolled 167 male and female 12- to 19-year-old athletes who experienced a sports-related concussion within 8 days of study enrollment and registering a Sports Concussion Assessment Tool 5 (SCAT5) composite score >7. INTERVENTIONS: Pro2cool, an investigational head-neck cooling therapy device, was applied at 2 postinjury time points compared with postconcussion standard of care only. MAIN OUTCOME MEASURES: Baseline SCAT5 composite symptom severity scores were determined for all subjects. Sports Concussion Assessment Tool 5 scores for concussed athletes receiving cooling treatment were analyzed across 6 independent postenrollment time points compared with subjects who did not receive cooling therapy and only standard care. Adverse reactions and participate demographics were also compared. RESULTS: Athletes who received Pro2cool cooling therapy (n = 79) experienced a 14.4% greater reduction in SCAT5 symptom severity scores at the initial visit posttreatment, a 25.5% greater reduction at the 72-hour visit posttreatment, and a 3.4% greater reduction at the 10-day visit compared with subjects receiving only standard care (n = 88). Overall, 36 adverse events (increased blood pressure, decreased pulse, and dizziness) were reported, with 13 events associated with the device, of which 3 were classified as moderate in severity. CONCLUSIONS: This study demonstrates the efficacy and safety of head and neck cooling for the management of concussion symptoms in adolescent athletes of an age group for which little to no prior data are available.

Factors influencing shared decision-making for insomnia and obstructive sleep apnea treatment among Veterans with mild traumatic brain injury.

STUDY OBJECTIVES: We elicited perspectives of clinical stakeholders and Veterans regarding barriers and facilitators to implementing shared decision-making (SDM) for comorbid mild traumatic brain injury (mTBI) and sleep disorders in the Veterans Health Administration. We also compared the perspectives of clinical stakeholders and Veterans regarding determinants of SDM. METHODS: Semistructured interviews were conducted with 29 clinical stakeholders and 20 Veterans (n = 49). Clinical stakeholders included Veterans Health Administration providers and policymakers involved in the management of mTBI and/or sleep disorders (insomnia disorder, obstructive sleep apnea). Veterans included those with a clinician-confirmed mTBI who received care for insomnia disorder and/or obstructive sleep apnea within the past year. Themes were identified using a descriptive and interpretive approach to qualitative analysis. We compared results across clinical stakeholders and Veterans. RESULTS: Barriers to implementing SDM were identified by both groups at the patient (eg, mTBI sequalae), provider (eg, deprioritization of Veteran preferences), encounter (eg, time constraints), and facility levels (eg, reduced care access). Similarly, both groups identified facilitators at the patient (eg, enhanced trust), provider (eg, effective communication), encounter (eg, decision support), and facility levels (eg, mitigating access barriers). Integrated services and provider discontinuity were factors identified by clinical stakeholders and Veterans alone, respectively. CONCLUSIONS: Our study revealed factors shaping the implementation of SDM at the levels of the patient, provider, encounter, and facility. Findings can inform the development of strategies aimed at implementing SDM for comorbid mTBI and sleep disorders, promoting patient-centered care and enhancing clinical outcomes.

A Critical Review of Existing Evidence-Based Sport Psychological Interventions for College Athletes with Comorbid Attention Deficit-Hyperactivity Disorder and Sport-Related Concussions.

ABSTRACT: The preventive efficacy of mental skills in reducing the risk of sport-related concussions (SRC), facilitating rehabilitation post-SRC, and enhancing mental performance was assessed in individuals with comorbid attention deficit-hyperactivity disorder (ADHD) and SRC. ADHD, characterized by behavioral disruptions linked to hyperactivity and impulsivity, poses an increased risk of severe injuries among student-athletes. Annually, over 10,000 mild Traumatic Brain Injuries (mTBI), including SRC, are diagnosed in National Collegiate Athletic Association (NCAA) student-athletes. Despite the high incidence, there remains a limited understanding of how sport psychological interventions can effectively prevent and rehabilitate SRC in student-athletes with ADHD. This article explores the intricate relationship between ADHD and SRC in NCAA-affiliated student-athletes, focusing on identifying optimal sport psychological interventions for injury prevention, treatment, and performance improvement. The analysis aims to inform the integration of this knowledge into comprehensive services for student-athletes, encompassing prevention, rehabilitation, and performance enhancement strategies.

Current Concussion Knowledge, Beliefs, Education, and Management Practices Among Irish Post-Primary PE Teachers.

Purpose: Physical education (PE) teachers play an important role in concussion recognition and management in schools both in an academic and activity based setting. This study aimed to identify Irish post-primary PE teachers' concussion knowledge, beliefs, education and management practices. Methods:  An anonymous online survey, adapted to the Irish context from the validated BAKPAC-TEACH, was completed by 128 PE teachers (female = 74/123; 60.2%; male = 49/123; 39.8%, 36.1 ± 10.9 years), representing 4% of registered PE teachers in Ireland. Results: PE teachers reported 3.5 ± 4.7 students suffer with a sports-related concussion in their classroom annually and 43.9% previously had a student sustain a concussion during their PE class. Most received concussion education (58.6%), largely provided by sporting bodies. They frequently identified dizziness (93.0%) and headaches (92.2%) as concussion symptoms, but less commonly emotional (more emotional = 36.5%, nervous or anxious = 33.6%, sadness = 28.9%) or sleep (35.2%) symptoms. All PE teachers knew that a concussion requires immediate removal from a game/practice. PE teachers demonstrated less perceived knowledge and confidence relating to academic adjustments and return to learn criteria. Just 31.3% reported their school facilitates academic adjustments. Conclusion: Tailored concussion education addressing knowledge gaps highlighted in this study should be developed. A concussion policy and an academic support team in each school should be established and widely publicised to enhance the support of concussed students in returning to school.

Early intervention treatment in the first 2 weeks following concussion in adults: A systematic review of randomised controlled trials.

OBJECTIVE: International guidelines support a repertoire of therapeutic interventions that may assist recovery following concussion. We aimed to systematically review the efficacy of early pharmacological and non-pharmacological interventions initiated within two weeks of injury on symptoms and functional recovery of adults with concussion. METHODS: We conducted a Systematic Review (SR) of Randomised Controlled Trials (RCTs) without meta-analysis utilising the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search was performed of four databases. Study inclusion criteria were adult participants diagnosed with concussion and commencing active intervention within 14 days of injury. RESULTS AND CONCLUSIONS: Of 7531 studies identified, 11 were included in the final review. Six studies were rated as high-risk of bias, three with some concerns and two as low-risk of bias. We found no evidence to support specific pharmacotherapeutic management to hasten the natural recovery time-course. Two studies reported significant improvement in selected concussion symptoms following manual therapy (at 48-72 hours post-treatment) or telephone counselling interventions (at 6 months post-injury). No high quality RCTs demonstrate superior effects of early therapeutic interventions on concussion recovery in the first 2 weeks. We advocate future research to examine impacts of health-clinician contact points aligned with symptom-specific interventions.

An overview of mild traumatic brain injuries and emerging therapeutic targets.

The majority of traumatic brain injuries (TBIs), approximately 90%, are classified as mild (mTBIs). Globally, an estimated 4 million injuries occur each year from concussions or mTBIs, highlighting their significance as a public health crisis. TBIs can lead to substantial long-term health consequences, including an increased risk of developing Alzheimer's Disease, Parkinson's Disease (PD), chronic traumatic encephalopathy (CTE), and nearly doubling one's risk of suicide. However, the current management of mTBIs in clinical practice and the available treatment options are limited. There exists an unmet need for effective therapy. This review addresses various aspects of mTBIs based on the most up-to-date literature review, with the goal of stimulating translational research to identify new therapeutic targets and improve our understanding of pathogenic mechanisms. First, we provide a summary of mTBI symptomatology and current diagnostic parameters such as the Glasgow Coma Scale (GCS) for classifying mTBIs or concussions, as well as the utility of alternative diagnostic parameters, including imaging techniques like MRI with diffusion tensor imaging (DTI) and serum biomarkers such as S100B, NSE, GFAP, UCH-L1, NFL, and t-tau. Our review highlights several pre-clinical concussion models employed in the study of mTBIs and the underlying cellular mechanisms involved in mTBI-related pathogenesis, including axonal damage, demyelination, inflammation, and oxidative stress. Finally, we examine a selection of new therapeutic targets currently under investigation in pre-clinical models. These targets may hold promise for clinical translation and address the pressing need for more effective treatments for mTBIs.

Patterns and Predictors of Health Care Utilization After Pediatric Concussion: A Retrospective Cohort Study.

OBJECTIVE: To characterize types, duration, and intensity of health care utilization following pediatric concussion and to identify risk factors for increased post-concussion utilization. METHODS: A retrospective cohort study of children 5 to 17 years old diagnosed with acute concussion at a quaternary center pediatric emergency department or network of associated primary care clinics. Index concussion visits were identified using International Classification of Diseases, Tenth Revision, Clinical Modification codes. We analyzed patterns of health care visits 6 months before and after the index visit using interrupted time-series analyses. The primary outcome was prolonged concussion-related utilization, defined as having ≥1 follow-up visits with a concussion diagnosis more than 28 days after the index visit. We used logistic regressions to identify predictors of prolonged concussion-related utilization. RESULTS: Eight hundred nineteen index visits (median [interquartile range] age, 14 [11-16] years; 395 [48.2%] female) were included. There was a spike in utilization during the first 28 days after the index visit compared to the pre-injury period. Premorbid headache/migraine disorder (adjusted odds ratio (aOR) 2.05, 95% confidence interval [CI] 1.09-3.89) and top quartile pre-injury utilization (aOR 1.90, 95% CI 1.02-3.52) predicted prolonged concussion-related utilization. Premorbid depression/anxiety (aOR 1.55, 95% CI 1.31-1.83) and top quartile pre-injury utilization (aOR 2.29, 95% CI 1.95-2.69) predicted increased utilization intensity. CONCLUSIONS: Health care utilization is increased during the first 28 days after pediatric concussion. Children with premorbid headache/migraine disorders, premorbid depression/anxiety, and high baseline utilization are more likely to have increased post-injury health care utilization. This study will inform patient-centered treatment but may be limited by incomplete capture of post-injury utilization and generalizability.

Early Identification and Management of Cervical Impairments in Pediatric Patients With Concussion May Reduce Risk of Delayed Recovery.

OBJECTIVE: Previous research, including high-quality systematic reviews, has found that cervical injury, which often accompanies concussive head injury, can delay recovery from concussion. One pilot randomized controlled trial found that focused cervical assessment and appropriate intervention in children and young adults with persisting postconcussive symptoms (PPCS) improved recovery outcomes. Our sports medicine clinics adopted this approach early (within 2 weeks) in children (aged 10-18 years) after concussion. This study describes our clinical management protocol and compares the recovery trajectories in children after concussion with and without a concomitant cervical injury. DESIGN: Prospective cohort study. SETTING: Three university-affiliated outpatient sports medicine clinics from September 2016 to December 2019. PATIENTS: One-hundred thirty-four concussed children with cervical impairment (mean age 14.9 years, 65% male, and 6.2 days since concussion) were compared with 130 concussed children without cervical impairment (mean age 14.9 years, 57% male, and 6.0 days since concussion). INDEPENDENT VARIABLES: Examination findings related to the cervical spine (range of motion, cervical spasm, and cervical tenderness). MAIN OUTCOME MEASURES: Recovery time (measured in days), concussion symptom burden (Postconcussion Symptom Scale), and incidence of PPCS. RESULTS: Children with cervical impairment reported a higher initial symptom burden; however, there were no differences in recovery time (33.65 [28.20-39.09] days vs 35.98 [27.50-44.45] days, P = 0.651) or incidence of PPCS (40.0% vs 34.3%, P = 0.340). CONCLUSIONS: We conclude that within this pediatric population, early identification and management of cervical injuries concomitant with concussion may reduce the risk of delayed recovery.
