Association Between Design Elements of Concussion Laws and Reporting of Sports-Related Concussions Among US High School Athletes, 2009-2017.

OBJECTIVES: Studies that evaluate the effectiveness of concussion laws often use only a single variable (ie, presence of the law), failing to account for law complexity. We examined the association between multiple design elements of state concussion laws and rates of sports-related concussion reporting among US high school athletes. METHODS: We derived 3 design elements of concussion laws from the 2009-2017 LawAtlas database: (1) strength of law, (2) number of law revisions, and (3) speed of law adoption. We examined the association between these design elements and rates of new and recurrent sports-related concussion reporting from the 2009-2010 through 2016-2017 academic years in a nationally representative sample of high school athletes participating in High School Report Information Online, an online data collection tool. RESULTS: A total of 7064 sports-related concussions (6332 [89.6%] new and 732 [10.4%] recurrent concussions) were reported during the study period, with an overall rate of 39.7 sports-related concussions per 100 000 athletic exposures (eg, game or practice). Rates of new concussion reporting were higher among high schools in states with medium- or high-strength concussion laws than in states with low-strength concussion laws and in states with at least 1 concussion law revision than in states with no concussion law revisions. Rates of recurrent concussion reporting were lower among high schools in states with ≥2 concussion law revisions than in states with <2 concussion law revisions. Early law adoption was associated with higher rates of new and recurrent concussion reporting, and late law adoption was associated with lower rates of new and recurrent concussion reporting. CONCLUSION: Our findings may help inform legislators of the public health effect of concussion laws.

Putting Policy Into Practice: School-Level Compliance With and Implementation of State Concussion Laws.

CONTEXT: Each year, approximately 2 million US children 18 years or younger sustain a concussion, a type of mild traumatic brain injury (TBI). Concussions can have detrimental effects on physical, cognitive, emotional, or sleep health. POLICY: Between 2009 and 2014, all 50 US states and Washington, District of Columbia, enacted state concussion laws aimed to increase awareness about concussion and reduce the prevalence and severity of this injury. Most state laws include the following core tenets: (1) immediate removal from play after an actual or suspected concussion; (2) medical clearance before an athlete can return to play (RTP); and (3) concussion education for athletes, parents, and coaches. IMPLEMENTATION: State concussion laws allow for substantial interpretation at the school level, resulting in considerable variation in the content of school written concussion policies and the level of implementation of state law requirements at the school level. EVALUATION: We assessed the degree of high school written concussion policy compliance with the respective state law and examined the relationship between concussion policy compliance and school-level implementation of concussion laws. Seventy-one school officials completed a semistructured telephone interview and submitted their school's written concussion policy. Of the 71 policies analyzed, most complied with the removal-from-play, RTP, and concussion education tenets (90.1%, 97.2%, and 76.1%, respectively). The majority of participants reported that their school implemented the removal-from-play (91.5%), RTP (93.0%), and concussion education (80.6%) tenets well or very well. No significant relationships were found between researcher-rated school policy compliance and school-reported implementation of state law requirements at the school level. DISCUSSION: Our findings suggest that most participating schools complied with their state concussion law and implemented law requirements well or very well. Future studies should identify facilitators and barriers to the implementation of state concussion laws at the school level.

Qualitative Evaluation of High School Implementation Strategies for Youth Sports Concussion Laws.

CONTEXT:: All 50 states and the District of Columbia have enacted laws governing concussion management and education. These concussion laws, featuring common tenets regarding removal from play, return to play, and concussion education, have shaped school and district policies. OBJECTIVE:: To evaluate the strategies commonly used to implement concussion laws at the school and district levels, as reported by certified athletic trainers (ATs). DESIGN:: Qualitative study. SETTING:: High schools. PATIENTS OR OTHER PARTICIPANTS:: We interviewed 64 ATs from high schools (1 per school) participating in High School Reporting Information Online. DATA COLLECTION AND ANALYSIS:: Interviews were conducted with participants between April and October 2015 regarding implementation of the 3 core tenets of concussion laws. Research team members independently evaluated the interview transcripts and field notes to identify common themes in implementation strategies. RESULTS:: Of the 64 schools represented, 90.6% were public schools, 89.1% sponsored more than 15 sports, and all schools employed at least 1 AT and had a written concussion policy. Four commonly used strategies to implement removal from play were reliance on coaches, immediate response, referral and guidance after injury, and notification of key individuals. Use of assessment or baseline tests, communication among parties involved, reliance on AT assessments, and return-to-learn policies were 4 frequent strategies to implement return to play. Finally, 3 major implementation strategies to effectuate concussion education were use of existing educational tools, timing of education, and concussion training for school professionals. CONCLUSIONS:: Although concussion laws were passed at different times and varied in content across states, common themes in implementation strategies emerged across jurisdictions. The identification of strategic approaches to implementation will help ensure proper concussion management and education, reducing negative health outcomes among youths with concussions.

Consistency and Variation in School-Level Youth Sports Traumatic Brain Injury Policy Content.

PURPOSE: The purpose of the study was to examine the consistency and variation in content of high school written traumatic brain injury (TBI) policies in relation to the three key tenets of youth sports TBI laws. METHODS: A content analysis was conducted on written TBI policies retrieved from 71 high schools currently participating in High School Reporting Information Online. Each policy was independently analyzed by two trained coders. The number and percent of the policies reflecting the three key tenets of state youth sports TBI laws were described and compared on policy enforcement (i.e., strictness of language), policy description (i.e., details and definitions of the requirements), and policy implementation steps (i.e., specific steps for implementing the requirements). Direct quotes were identified to support quantitative findings. RESULTS: All 71 high school TBI policies contained at least two of the three main TBI law tenets, where 98.6% (n = 70) included the return to play tenet, 83.1% (n = 59) included the removal from play tenet, and 59.2% (n = 42) specified the distribution of TBI information sheets to student-athletes and their parents. Nearly half of the policies (49.3%, n = 35) required parents' signature while only 39.4% (n = 28) required students' signature on the TBI information sheet. The language exhibited wide variance across the 71 TBI policies regarding policy enforcement, policy description, and policy implementation specifications. CONCLUSIONS: All 71 TBI policies covered at least two of the three youth sports TBI law tenets, but with considerable variation. Future research should assess variations by schools within the same state and their impact on TBI rates in school athletics.

New and Recurrent Concussions in High-School Athletes Before and After Traumatic Brain Injury Laws, 2005-2016.

OBJECTIVES: To examine the trends of new and recurrent sports-related concussions in high-school athletes before and after youth sports traumatic brain injury laws. METHODS: We used an interrupted time-series design and analyzed the concussion data (2005-2016) from High School Reporting Injury Online. We examined the trends of new or recurrent concussion rates among US representative high-school athletes participating in 9 sports across prelaw, immediate-postlaw, and postlaw periods by using general linear models. We defined 1 athlete exposure as attending 1 competition or practice. RESULTS: We included a total of 8043 reported concussions (88.7% new, 11.3% recurrent). The average annual concussion rate was 39.8 per 100 000 athlete exposures. We observed significantly increased trends of reported new and recurrent concussions from the prelaw, through immediate-postlaw, into the postlaw period. However, the recurrent concussion rate showed a significant decline 2.6 years after the laws went into effect. Football exhibited different trends compared with other boys' sports and girls' sports. CONCLUSIONS: Observed trends of increased concussion rates are likely attributable to increased identification and reporting. Additional research is needed to evaluate intended long-term impact of traumatic brain injury laws.

Genomic Test Results and the Courtroom: The Roles of Experts and Expert Testimony.

The rapid advancement from single-gene testing to whole genome sequencing has significantly broadened the type and amount of information available to researchers, physicians, patients, and the public in general. Much debate has ensued about whether genomic test results should be reported to research participants, patients and consumers, and at what stage we can be sure that existing evidence justifies their use in clinical settings. Courts and judges evaluating the utility of these results will not be immune to this uncertainty. As scholars increasingly explore the duty of care standards related to reporting genomic test results, it is timely to provide a framework for understanding how uncertainty about genetic and genomic tests influences evidentiary considerations in the court room. Here, we explore the subtleties and nuances of interpreting genetic data in an environment of substantial discord related to the value that individuals should place on genetic and genomic tests. In conjunction, we discuss the roles courts should play in qualifying experts, expert testimony, and genetic and genomic tests given the intricate and complex nature of genetic and genomic information.

Refereeing the public health.

Between January 2009 and October 2013, 49 states and the District of Columbia passed laws focusing on mitigating the consequences of traumatic brain injuries (TBIs) in organized youth sports. Using historical, contextual, and empirical methods, this Article describes the content, goals, and structure of youth sports TBI laws, while hypothesizing about their underlying legislative logic and long-term public health consequences. The Article's empirical evidence suggests two key findings: first, that a dominant interest group, the National Football League, helped to define the problem and its associated solutions for the vast majority of states, thus curving the legislative story are in favor of its policy prescriptions; second, that existing youth sports TBI laws are focused on secondary, not primary, prevention, and may thus shift attention away from more comprehensive solutions. Finally, the Article explains why such state laws will likely fail to substantially resolve the larger untackled problem--significantly reducing the overall rate and number of TBIs in youth sports. After explaining why existing state youth sports TBI laws fail to accomplish this broader goal, the Article queries whether alternative policy or public health measures might offer more robust solutions.

Reducing traumatic brain injuries in youth sports: youth sports traumatic brain injury state laws, January 2009-December 2012.

OBJECTIVES: I sought to describe current state-wide youth sports traumatic brain injury (TBI) laws and their relationship to prevailing scientific understandings of youth sports TBIs, and to facilitate further research by creating an open-source data set of current laws. METHODS: I used Westlaw and LexisNexis databases to create a 50-state data set of youth sports TBI laws enacted between January 2009 and December 2012. I collected and coded the text and citations of each law and developed a protocol and codebook to facilitate future research. RESULTS: Forty-four states and Washington, DC, passed youth sports TBI laws between 2009 and 2012. No state's youth sports TBI law focuses on primary prevention. Instead, such laws focus on (1) increasing coaches' and parents' ability to identify and respond to TBIs and (2) reducing the immediate risk of multiple TBIs. CONCLUSIONS: Existing youth sports TBI laws were not designed to reduce initial TBIs. Evaluation is required to assess their effectiveness in reducing the risk and consequences of multiple TBIs. Continued research and evaluation of existing laws will be needed to develop a more comprehensive youth TBI-reduction solution.
