Concussion Epidemiology in Youth Sports: Sports Study of a Statewide High School Sports Program.

BACKGROUND: Current research on concussion incidence in youth athletes (age <18 years) is small and limited by variability in injury reporting and diagnostic methodology. HYPOTHESIS: Concussion injuries commonly occur in high school sports programs. The likelihood of concussion among student-athletes (aged 13-18 years) depends on the sport they are participating in as well as the sex of the athlete. STUDY DESIGN: Descriptive epidemiology study. LEVEL OF EVIDENCE: Level 4. METHODS: A retrospective analysis of all Hawaii high school athletes aged 13 to 18 years participating in 14 sports from 2011 through 2017 was performed as part of a statewide standardized concussion assessment and management program. RESULTS: A total of 5993 concussions were identified among 92,966 athletes. The overall concussion rate was 0.96 (95% CI, 0.94-0.99). Girls' judo had the highest concussion rate (1.92; 95% CI, 1.68-2.17) followed by football (1.60; 95% CI, 1.53-1.66). The concussion rate for boys (1.0; 95% CI, 0.97-1.03) was higher than that for girls (0.91; 95% CI, 0.87-0.95); however, in 4 of the 5 sports in which both girls and boys participated, girls had a higher rate of concussion injury. CONCLUSION: The likelihood of concussion among student-athletes aged 13 to 18 years may be higher than previously thought and varies depending on sport and sex. CLINICAL RELEVANCE: Epidemiologic data on concussion injury in children and adolescents are useful in accurately determining the relative risks of high school sports participation and may be valuable in determining the appropriate allocation of health care and scholastic resources for student-athletes, as well as the impact of rule and training modifications designed to improve participant safety.

The use of pregame hyperhydration with intravenous fluids in National Collegiate Athletic Association Football Bowl Subdivision teams.

OBJECTIVE: To determine the frequency of pregame intravenous fluid hyperhydration (PIVFH) usage, administration protocols, indications, complications, and perceived efficacy by National Collegiate Athletic Association Football Bowl Subdivision (NCAA-FBS) teams. DESIGN: Cross-sectional survey study. SETTING: National Collegiate Athletic Association Football Bowl Subdivision. PARTICIPANTS: Head athletic trainers from NCAA-FBS institutions. INTERVENTION: Voluntary, anonymous 15-item validated online survey instrument. MAIN OUTCOME MEASURES: Number of teams reporting use of PIVFH. RESULTS: The survey response rate was 64% (77 of 120). Thirty percent of respondents reported the utilization of PIVFH, administered to an average of 2 to 3 players. The most common reasons cited for using PIVFH were to prevent muscle cramps (95%), heat illness (79%), and dehydration (68%). Additionally, 47% of programs used PIVFH to improve player exercise tolerance and 47% per player request. Twenty-four percent of programs that used PIVFH reported the occurrence of associated complications. Only 15% of respondents believed that PIVFH improved their teams' overall performance. CONCLUSIONS: PIVFH is a common practice among NCAA-FBS teams. PIVFH is used most often to prevent muscle cramps, dehydration, and heat illness. The relatively few numbers of players per team who receive PIVFH suggest that higher risk individuals were targeted for administration.
