Mild traumatic brain injury as a pathological process

Traumatic brain injury (TBI) is defined as dysfunction or other evidence of brain pathology caused by external physical force. More than 69 million new cases of TBI are registered worldwide each year, 80% of them - mild TBI. Based on the physical mechanism of induced trauma, we can separate its pathophysiology into primary and secondary injuries. Many literature sources have confirmed that mechanically induced brain injury initiates ionic, metabolic, inflammatory, and neurovascular changes in the CNS, which can lead to acute, subacute, and chronic neurological consequences. Despite the global nature of the disease, its high heterogeneity, lack of a unified classification system, rapid fluctuation of epidemiological trends, and variability of long-term consequences significantly complicate research and the development of new therapeutic strategies. In this review paper, we systematize current knowledge of biomechanical and molecular mechanisms of mild TBI and provide general information on the classification and epidemiology of this complex disorder.

An intervention to improve knowledge and increase comfort of concussion management among school medical staff

BACKGROUND

Concussion can negatively impact a child's ability to learn. School-based health professional staff have a unique opportunity to monitor students during recovery and mitigate the potential negative impact. Little is known about school health professional staff's knowledge and comfort with concussion diagnosis and management.

OBJECTIVES

We aimed to evaluate whether a tailored concussion education session could improve school health professional staff's knowledge about pediatric concussions. A secondary aim was to determine their knowledge retention and comfort with concussion management over the following year, including the impact of periodic follow-up education. We hypothesized that there would be sustained improvement in concussion knowledge and self-reported comfort in concussion management.

STUDY DESIGN

This study was a pre/post-intervention assessment with longitudinal follow-up. The study investigators provided a three-hour educational presentation about concussions in school-aged children. A survey on knowledge and management of pediatric concussions was administered immediately before and after this educational intervention. Knowledge retention and comfort with management was assessed at six months and at one year post-intervention.

PARTICIPANTS AND SETTING

Participants included Cincinnati Health Department school health professional staff in attendance at their Back to School in-service, prior to the start of the 2017-2018 school year.

RESULTS

Sixty school health professional staff from thirty-three schools completed the baseline knowledge survey, and forty completed all four assessments. Among the 40 participants with complete data, on average, the correct response rate (mean number correct, SD) was 82.3% (18.1/22, 11.0) pre-education, 91.8% (20.2/22, 10.3) immediate post-education, 86.4% (19.0/22, 10.8) 6-month follow-up, and 87.3% (19.2/22, 10.9) one-year follow-up.

CONCLUSIONS

A brief didactic educational intervention improved pediatric concussion knowledge and management skills among school health care providers. Periodic and in-person education is likely necessary to optimize knowledge retention.

The role of AT-SLP collaborations in return to academics following mTBI: A scoping review

Return-to-academics (RTA) for student-athletes with mild traumatic brain injury (mTBI) is crucial, but relatively understudied compared to return-to-play (RTP). The transient and unpredictable nature of symptoms surrounding mTBI often results in underreporting of neurocognitive symptoms, leading to a greater susceptibility for repeated TBIs, as well as posing impediments to the process of RTA. Athletic Trainers (ATs) and Speech-Language Pathologists (SLPs) are in a unique position to help student-athletes achieve a safe, timely, and effective RTA following mTBI. They typically work in middle/high schools and collegiate-level academic settings and often serve as members of concussion management teams. Compared to other allied health professions, ATs and SLPs are relatively new professions with evolving scopes of practice. Despite established guidelines and recommendations for their scope of practice in treating student-athletes with mTBI, there is a lacuna in research regarding their individual and collaborative roles in achieving RTA. The current scoping review was conducted with the main goal of exploring published literature pertaining to the roles of ATs and SLPs in achieving RTA for student-athletes with mTBI. Current implications, recommendations for integrating pre-service interprofessional education (IPE) experiences, and future directions for AT-SLP collaborations are discussed.

School nurses' perceptions of concussion management for secondary school student-athletes

Background: School nurses play a vital role in concussion management at the secondary school level, often being the only on-site healthcare provider during school hours. However, little is known regarding how they perceive their role in the concussion management process. The purpose of this study was to explore school nurses' perceptions and satisfaction with concussion management in the secondary school setting using a qualitative approach.Methods: Twenty-two school nurses employed within a United States secondary school setting completed individual, semi-structured phone interviews. Data were analyzed using a consensual qualitative research approach.Results: Four overall themes emerged. This manuscript focuses on one specific theme: school nurse perceptions and satisfaction regarding concussion management. Subthemes included: school nurses' overall perception and satisfaction with current concussion management procedures, interactions with other involved personnel, concussion assessment tools, school nurses' perceived role, current concussion management policies, concussion education, and school nurse continuing education specific to concussion.Conclusions: School nurses were generally positive regarding concussion management within their setting and were satisfied with their roles overall. However, participants identified a number of areas that require further attention to ensure an evidence-based, consistent team approach to concussion management to support best student outcomes and continuity of care.

School Nurses' Management and Collaborative Practices for Student-Athletes Following Sport-Related Concussion

The purpose of this study was to examine school nurses' management and collaboration with health-care providers (HCPs) for student-athletes following a concussion. Secondary school nurses accessed an online survey titled the Beliefs, Attitudes, and Knowledge of Pediatric Athletes with Concussions (access rate = 15.6%; n = 1,246/8,000). Approximately 40% of schools where nurses were employed administered baseline and postinjury concussion assessments. No significant differences were found between employment model (single vs. multiple sites) in regard to conducting baseline (p = .908) administration at their site; however, those employed at a single school more frequently offered postinjury assessments at their site than those at multiple sites (p = .019). School nurses most frequently reported relationships with an athletic trainer (38.8%, n = 483/1,246) compared to other HCPs. A concussion management team, including school nurses, and other recommended members should develop comprehensive concussion management plans. Plans should comprise of multiple concussion assessments to aid in the return-to-learn/play processes.

Athletic Trainers’ Perceived Challenges Toward Comprehensive Concussion Management in the Secondary School Setting

Available financial and personnel resources often dictate the specifics of concussion policies and procedures in the secondary school setting. The purpose of this qualitative study was to explore athletic trainers’ perceived challenges toward comprehensive concussion management in the secondary school setting. The findings indicate several challenges exist toward concussion management in the secondary school, including facility, personnel, and community resources, education levels of various stakeholders, and general perceptions of concussion and athletic trainers. It is important to identify challenges athletic trainers may face in order to develop strategies to align current concussion management procedures with current best practices.

What Definition Is Used to Describe Second Impact Syndrome in Sports? A Systematic and Critical Review

Concern about what has been termed, "second impact syndrome" (SIS) is a major factor determining return-to-play decisions after concussion. However, definitions of SIS vary. We used Scopus to conduct a systematic review and categorize the definitions used to describe SIS. Of the 91 sources identified, 79 (87%) clearly specified that SIS involved either cerebral edema or death after a concussion when a prior concussion had not resolved. Twelve articles (13%) could be interpreted as merely the events of two consecutive concussions. Among the articles that listed mortality rates, nearly all (33/35, 94%) said the rate of death was "high" (e.g., 50% to 100%). Our review found that most articles define SIS as a syndrome requiring catastrophic brain injury after consecutive concussive episodes. Given that it is unclear how common it is to have a second concussion while not fully recovered from a first concussion, the actual mortality rate of SIS is unknown.

Management of Sport-Related Concussion in the Pediatric and Adolescent Population

Concussions make up nearly 10% of all high school athletic injuries. Recent changes in concussion management guidelines and legislation aim to make concussion care more standardized and safe but simultaneously pose a challenge for the primary care and sports medicine physician. Pediatric and adolescent concussions may cause anxiety for the treating physician due to concerns over return-to-play decisions, academic issues, and the potential for second impact syndrome. Determining when to refer a patient to an emergency department acutely, to an outpatient concussion clinic, or to other subspecialists may be a difficult decision for the primary care physician. The aim of this article is to review current evidence regarding concussion treatment and return-to-school and return-to-play recommendations to provide the primary care and sports medicine physician with practical guidelines for managing concussions.

Heads Up: Communication Is Key in School Nurses' Preparedness for Facilitating "Return to Learn" Following Concussion

BACKGROUND

Recent literature advocates for a school academic team, including school nurses, to support concussed students' return to the classroom. This study aimed to assess the current understanding and practices of a sample of school nurses regarding the concept of "return to learn" in concussed students.

METHODS

Cross-sectional survey of New England school nurses.

RESULTS

The greatest barrier to the school nurses' functioning within the academic rehabilitation team for students with concussion was "inadequate communication with the provider that diagnosed the concussion" (73%). Of the 151 school nurses surveyed, 19% felt that they did not have the training necessary for this role. Other barriers included "inadequate concussion training" (38%) and "inadequate time necessary to care for a student with concussion" (30%).

CONCLUSIONS

By identifying specific gaps in knowledge and challenges at the school level, these results inform interdisciplinary medical teams about the importance of educating and facilitating effective "return to learn" academic plans.

Athletic trainers' familiarity with and perceptions of academic accommodations in secondary school athletes after sport-related concussion

CONTEXT

Sport-related concussion can affect athletes' sport participation and academic success. With the recent emphasis on cognitive rest, student-athletes may benefit from academic accommodations (AA) in the classroom; however, athletic trainers' (ATs') perceived familiarity with, and use of, AA is unknown.

OBJECTIVE

To assess secondary school ATs' perceived familiarity with, attitudes and beliefs about, and incorporation of AA for student-athletes after sport-related concussion. A secondary purpose was to determine whether employment status altered familiarity and use of AA.

DESIGN

Cross-sectional study.

SETTING

Online survey.

PATIENTS OR OTHER PARTICIPANTS

Of 3286 possible respondents, 851 secondary school ATs accessed the survey (response rate = 25.9%; 308 men [36.2%], 376 women [44.2%], 167 respondents [19.6%] with sex information missing; age = 37.3 ± 10.1 years).

MAIN OUTCOME MEASURE(S)

Participants were solicited via e-mail to complete the Beliefs, Attitudes and Knowledge Following Pediatric Athlete Concussion among Athletic Trainers employed in the secondary school setting (BAKPAC-AT) survey. The BAKPAC-AT assessed ATs' perceived familiarity, perceptions, and roles regarding 504 plans, Individualized Education Programs (IEPs), and returning student-athletes to the classroom. Independent variables were employment status (full time versus part time), employment model (direct versus outreach), years certified, and years of experience in the secondary school setting. The dependent variables were participants' responses to the AA questions. Spearman rank-correlation coefficients were used to assess relationships and Mann-Whitney U and χ(2) tests (P < .05) were used to identify differences.

RESULTS

Respondents reported that approximately 41% of the student-athletes whose sport-related concussions they managed received AA. Respondents employed directly by the school were more familiar with 504 plans (P < .001) and IEPs (P < .001) and had a greater belief that ATs should have a role in AA. Both the number of years certified and the years of experience at the secondary school were significantly correlated with perceived familiarity regarding 504 plans and IEPs.

CONCLUSIONS

The ATs employed directly by secondary schools and those with more experience as secondary school ATs were more familiar with AA. Understanding AA is important for all ATs because cognitive rest and "return to learn" are becoming more widely recommended in concussion management.

Current and emerging rehabilitation for concussion: a review of the evidence

Concussion is one of the most hotly debated topics in sports medicine today. Research surrounding concussion has experienced significant growth recently, especially in the areas of incidence, assessment, and recovery. However, there is limited research on the most effective rehabilitation approaches for this injury. This review evaluates the current literature for evidence for and against physical and cognitive rest and the emerging areas targeting vestibular, oculomotor, and pharmacologic interventions for the rehabilitation of sport-related concussion.

Managing concussion in the school setting

Concussion is a significant injury that can occur in physical education, during recreational activities, and during sports. School nurses should be included as an integral member of the concussion management team and assist with education, evaluation, and management of a concussed student. Recent and updated sport-related concussion management recommendations from the National Athletic Trainers' Association Research and Education Foundation as published in the March 2014 Journal of Athletic Training are reviewed to provide an understanding of best practices for concussion management in the school setting.

School nurses' familiarity and perceptions of academic accommodations for student-athletes following sport-related concussion

The purpose of this study was to evaluate school nurses' familiarity and perceptions regarding academic accommodations for student-athletes following sport-related concussion. School nurses (N = 1,246) accessed the survey School Nurses' Beliefs, Attitudes and Knowledge of Pediatric Athletes with Concussions (BAKPAC-SN). The BAKPAC-SN contained several questions pertaining to concussion management and academic accommodations. There were significant differences regarding personal experience as well as familiarity of academic accommodations (p < .001) between school nurses who work at a school that employs an athletic trainer and school nurses who work at a school that does not employ an athletic trainer. There were significant weak positive relationships between years of experience and familiarity with academic accommodations (r = .210, p < .001), 504 plans (r = .243, p < .001), and individualized education plans (r = .205, p < .001). School nurses employed at a single school were significantly more familiar with academic accommodations (p = .027) and 504 plans (p = .001) than school nurses employed at multiple schools. Health care professionals should collaborate to effectively manage a concussed patient and should consider academic accommodations to ensure whole-person health care.

Returning to learning following a concussion

Following a concussion, it is common for children and adolescents to experience difficulties in the school setting. Cognitive difficulties, such as learning new tasks or remembering previously learned material, may pose challenges in the classroom. The school environment may also increase symptoms with exposure to bright lights and screens or noisy cafeterias and hallways. Unfortunately, because most children and adolescents look physically normal after a concussion, school officials often fail to recognize the need for academic or environmental adjustments. Appropriate guidance and recommendations from the pediatrician may ease the transition back to the school environment and facilitate the recovery of the child or adolescent. This report serves to provide a better understanding of possible factors that may contribute to difficulties in a school environment after a concussion and serves as a framework for the medical home, the educational home, and the family home to guide the student to a successful and safe return to learning.

Sport-related concussion in adolescents

Sport-related concussion is a common problem encountered by pediatricians and other primary care physicians. Assessment of concussion is based on clinical evaluation. The Zurich consensus statement provides a basic framework to guide concussion management decisions and recommends an individualized approach and the exercising of clinical judgment in return-to-play decisions. This article reviews practice aspects of concussion for the adolescent athletes who present in the primary care office or clinic setting.
