Eye Protection and Risk of Eye Injuries in High School Field Hockey

Pediatric Sport-Related Concussion: Recommendations From the Amsterdam Consensus Statement 2023

The 6th International Consensus Conference on Concussion in Sport, Amsterdam 2022, addressed sport-related concussion (SRC) in adults, adolescents, and children. We highlight the updated evidence-base and recommendations regarding SRC in children (5-12 years) and adolescents (13-18 years). Prevention strategies demonstrate lower SRC rates with mouthguard use, policy disallowing bodychecking in ice hockey, and neuromuscular training in adolescent rugby. The Sport Concussion Assessment Tools (SCAT) demonstrate robustness with the parent and child symptom scales, with the best diagnostic discrimination within the first 72 hours postinjury. Subacute evaluation (>72 hours) requires a multimodal tool incorporating symptom scales, balance measures, cognitive, oculomotor and vestibular, mental health, and sleep assessment, to which end the Sport Concussion Office Assessment Tools (SCOAT6 [13+] and Child SCOAT6 [8-12]) were developed. Rather than strict rest, early return to light physical activity and reduced screen time facilitate recovery. Cervicovestibular rehabilitation is recommended for adolescents with dizziness, neck pain, and/or headaches for greater than 10 days. Active rehabilitation and collaborative care for adolescents with persisting symptoms for more than 30 days may decrease symptoms. No tests and measures other than standardized and validated symptom rating scales are valid for diagnosing persisting symptoms after concussion. Fluid and imaging biomarkers currently have limited clinical utility in diagnosing or assessing recovery from SRC. Improved paradigms for return to school were developed. The variable nature of disability and differences in evaluating para athletes and those of diverse ethnicity, sex, and gender are discussed, as are ethical considerations and future directions in pediatric SRC research.

Field Hockey-Related Injuries Treated in US Emergency Departments, 2000 to 2020

OBJECTIVE

To describe the epidemiology of field hockey-related injuries of patients aged 6 to 24 years who were treated in US emergency departments from 2000 to 2020.

DESIGN

The researchers conducted a retrospective analysis using data from the National Electronic Injury Surveillance System (NEISS).

SETTING

The NEISS collects data on recreational activity-related and consumer product-related injuries treated in US Eds.

PATIENTS

Patients aged 6 to 24 years who were treated for field hockey-related injuries in Eds from 2000 to 2020.

INDEPENDENT VARIABLES

The researchers analyzed characteristics that included age, body part injured, injury diagnosis, disposition from the ED, injury locale, injury mechanism, contact, and equipment type.

MAIN OUTCOME MEASURES

All cases of field hockey-related injuries were identified using the NEISS product code for field hockey (1295).

RESULTS

There were an estimated 82 639 (95% CI = 45 536-119 742) field hockey-related injuries for patients aged 6 to 24 years treated in US emergency departments from 2000 to 2020. The rate of field hockey-related injuries per 100 000 population did not significantly change from 7.4 in 2000 to 7.4 in 2011 (slope = 0.048; P = 0.581) but significantly decreased from 7.4 in 2011 to 3.7 in 2019 (slope = -0.40; P = 0.018). As player age increased, the risk of injury due to contact with equipment increased ( 13 years: RR = 0.90; 95% CI = 0.82-0.98, 19-24 years: RR = 1.17; 95% CI = 1.06-1.29). Concussions or traumatic brain injuries accounted for 9.2% of injuries and were most associated with contact with the ball.

CONCLUSION

Although there was a decrease in the field hockey-related injuries, field hockey remains an important source of injuries for children and young adults.

International Olympic Committee (IOC) consensus paper on sports-related ophthalmology issues in elite sports

Vision plays an important role in an athletes' success. In sports, nearly 80% of perceptual input is visual, and eye health and sports medicine are closely intertwined fields of utmost importance to athletes. The physical nature of sports activities renders individuals more prone to various eye injuries than the general population. Ocular trauma can lead to lifelong sequelae, and impaired vision requires careful follow-up and management. Apart from injuries, athletes may also experience vision problems that can hamper their performance, including blurred vision, double vision, and light sensitivity. The interdisciplinary nature of sports medicine necessitates collaboration between sports medicine professionals and ophthalmologists. Through such collaborations, athletes can receive appropriate eye care, education on proper eye protection and guidance on adopting good eye health practices. If any inconspicuous symptoms are not detected and treated promptly, athletes may acquire systemic injuries because of defective vision, preventing them from achieving high level athletic performance in competitions. The protection of the elite athlete is the responsibility of all of us in sports medicine. To advance a more unified, evidence-informed approach to ophthalmic health assessment and management in athletes and as relevant for sports medicine physicians, the International Olympic Committee Consensus Group aims for a critical evaluation of the current state of the science and practice of ophthalmologic issues and illness in high-level sports, and present recommendations for a unified approach to this important issue.

Prevention strategies and modifiable risk factors for sport-related concussions and head impacts: a systematic review and meta-analysis

OBJECTIVES

To evaluate prevention strategies, their unintended consequences and modifiable risk factors for sport-related concussion (SRC) and/or head impact risk.

DESIGN

This systematic review and meta-analysis was registered on PROSPERO (CRD42019152982) and conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

DATA SOURCES

Eight databases (MEDLINE, CINAHL, APA PsycINFO, Cochrane (Systematic Review and Controlled Trails Registry), SPORTDiscus, EMBASE, ERIC0 were searched in October 2019 and updated in March 2022, and references searched from any identified systematic review.

ELIGIBILITY CRITERIA

Study inclusion criteria were as follows: (1) original data human research studies, (2) investigated SRC or head impacts, (3) evaluated an SRC prevention intervention, unintended consequence or modifiable risk factor, (4) participants competing in any sport, (5) analytic study design, (6) systematic reviews and meta-analyses were included to identify original data manuscripts in reference search and (7) peer-reviewed. Exclusion criteria were as follows: (1) review articles, pre-experimental, ecological, case series or case studies and (2) not written in English.

RESULTS

In total, 220 studies were eligible for inclusion and 192 studies were included in the results based on methodological criteria as assessed through the Scottish Intercollegiate Guidelines Network high ('++') or acceptable ('+') quality. Evidence was available examining protective gear (eg, helmets, headgear, mouthguards) (n=39), policy and rule changes (n=38), training strategies (n=34), SRC management strategies (n=12), unintended consequences (n=5) and modifiable risk factors (n=64). Meta-analyses demonstrated a protective effect of mouthguards in collision sports (incidence rate ratio, IRR 0.74; 95% CI 0.64 to 0.89). Policy disallowing bodychecking in child and adolescent ice hockey was associated with a 58% lower concussion rate compared with bodychecking leagues (IRR 0.42; 95% CI 0.33 to 0.53), and evidence supports no unintended injury consequences of policy disallowing bodychecking. In American football, strategies limiting contact in practices were associated with a 64% lower practice-related concussion rate (IRR 0.36; 95% CI 0.16 to 0.80). Some evidence also supports up to 60% lower concussion rates with implementation of a neuromuscular training warm-up programme in rugby. More research examining potentially modifiable risk factors (eg, neck strength, optimal tackle technique) are needed to inform concussion prevention strategies.

CONCLUSIONS

Policy and rule modifications, personal protective equipment, and neuromuscular training strategies may help to prevent SRC.

TFOS lifestyle: Impact of societal challenges on the ocular surface

Societal factors associated with ocular surface diseases were mapped using a framework to characterize the relationship between the individual, their health and environment. The impact of the COVID-19 pandemic and mitigating factors on ocular surface diseases were considered in a systematic review. Age and sex effects were generally well-characterized for inflammatory, infectious, autoimmune and trauma-related conditions. Sex and gender, through biological, socio-economic, and cultural factors impact the prevalence and severity of disease, access to, and use of, care. Genetic factors, race, smoking and co-morbidities are generally well characterized, with interdependencies with geographical, employment and socioeconomic factors. Living and working conditions include employment, education, water and sanitation, poverty and socioeconomic class. Employment type and hobbies are associated with eye trauma and burns. Regional, global socio-economic, cultural and environmental conditions, include remoteness, geography, seasonality, availability of and access to services. Violence associated with war, acid attacks and domestic violence are associated with traumatic injuries. The impacts of conflict, pandemic and climate are exacerbated by decreased food security, access to health services and workers. Digital technology can impact diseases through physical and mental health effects and access to health information and services. The COVID-19 pandemic and related mitigating strategies are mostly associated with an increased risk of developing new or worsening existing ocular surface diseases. Societal factors impact the type and severity of ocular surface diseases, although there is considerable interdependence between factors. The overlay of the digital environment, natural disasters, conflict and the pandemic have modified access to services in some regions.

A 5-Year Retrospective Assessment of Clinical Presentation Associated With Sports Injury in Young People Presenting to a Tertiary Eye Center

PURPOSE

To examine the incidence and initial presentation of sports-related ocular injury in youth.

METHODS

This retrospective case series study was performed at Massachusetts Eye and Ear, Boston, Massachusetts. Inclusion criteria were visit dates between January 1, 2010 and December 31, 2015, age 5 to 25 years, an ocular injury International Classifcation of Disease code, and a sports-related mechanism of injury.

RESULTS

The final sample was 223 patients, representing approximately 20% of all youth eye injuries (mean age: 16.2 years (range: 6 to 24 years); 78.9% boys, 21.2% girls). The most common diagnosis was hyphema (72.2%). Most injuries occurred with soccer (23.3%), baseball (17.0%), and basketball (11.7%), with a mean visual acuity of 20/40, 20/50, and 20/50, respectively. The injuries with the lowest mean visual acuity resulted from paintball (20/500) and airsoft gun shooting (20/200). Thirty-three patients (14.7%) required surgical intervention. The average number of follow-up visits within 1 year was five.

CONCLUSIONS

Approximately 20% of youth ocular injury visits were sports related, with male teenagers affected most. Hyphema was the most common type of sports-related eye injury posing a lifelong risk of ocular complications. Popular youth sports such as soccer, baseball, and basketball caused the most eye injuries. Shooting sports with paintball and airsoft guns were associated with the greatest loss of vision. Patients infrequently reported the use of protective eyewear at the time of injury. Protective eye equipment should be worn by youth participating in sports to prevent ocular trauma and the potential for surgical intervention. [J Pediatr Ophthalmol Strabismus. 2021;58(6):377-384.].

Video Analysis of Acute Injuries in Elite Field Hockey

OBJECTIVE

With this study, we aim to determine the value of video assessment of acute injuries in field hockey.

DESIGN

Retrospective video analysis for acute injuries.

SETTING

Professional field hockey.

PARTICIPANTS

Seven women and men's field hockey tournaments (World League, Champions Trophy) in 2015.

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

An injury was defined as any new musculoskeletal complaint leading to time stoppage and medical attention. The outcome measures were time at play, location on the pitch, type of injury, injured body part, and injury mechanism.

RESULTS

A total of 190 injuries occurred in 179 matches (55/73 female and 135/106 male matches). There were 0.75 injuries per match for women [confidence interval (CI, 0.31-1.13)] and 1.27 injuries per match for men (CI, 0.88-1.61). The number of injuries per 1000 player match hours was 34.20 for women (CI, 14.04-51.29) and 57.89 for men (CI, 29.78-73.12). The highest injury frequency occurred within the third quarter and within the circle. Contusion was the most common injury type (90.9% in women and 96.3% in men). The leading causes of injuries were hits by the ball or stick and collisions with another player. The head/face was the most affected body part in both sex groups (32.7% in women and 29.6% in men).

CONCLUSIONS

Video analysis revealed data on injury incidence within the same range of previous reports in elite field hockey. Its advantages, such as slow motion and repetitive play of injury scenes, could contribute valuable information if incorporated into the injury recording process.

Data-Driven Risk Classification of Concussion Rates: A Systematic Review and Meta-Analysis

BACKGROUND

Concussion is a growing public health concern and generating concussion prevention programs depends on identifying high-risk sports and characteristics. Identifying the roles of sport, sex, and participation level (e.g., high school versus collegiate athletics) in concussion risk would facilitate more informed decision-making regarding sports participation and generate better targeted prevention strategies.

OBJECTIVES

The current study's objectives were to: (1) determine the magnitude and hierarchy of sports-related concussion (SRC) risk across an array of events and (2) evaluate the modifying roles of sex, participation level, and session type on SRC rates.

METHODS

A literature search was conducted on PubMed, searching concussion studies published between 2001 and December 2019. Inclusion criteria for studies required: (1) concussion occurred during sport, (2) that the SRC was clinically diagnosed, and (3) athlete exposures and concussions could be extracted or estimated. A study was excluded if it: (1) was not an original research article, (2) was not written in English language, (3) was an animal study, (4) did not have enough data to calculate SRC rates, (5) included professional or youth sample, and/or (6) contained data collected prior to 2001. The meta-analysis and meta-regression analyses were fit using a random effects model.

RESULTS

Search results returned 2695 unique research articles, with 83 studies included in analyses. Sport, sex, participation level, and session type all significantly influenced SRC rates. Overall, rugby had the highest concussion rate and was classified as the highest risk sport (28.25 concussions per 10,000 athlete exposures). Overall, females had a higher concussion rate than males. Only lacrosse demonstrated a higher concussion rate for males compared to females. Collegiate athletes had higher concussion rates than high school athletes. Games were associated with 2.01 more concussions per 10,000 AEs than practices.

CONCLUSIONS

This meta-analysis demonstrated rugby has the highest concussion risk, followed by American Football, ice hockey, and wrestling. Concussion risk was influenced by sport, sex, participation, and session. Identifying the factors and environments that influence concussion risk can facilitate risk reduction and prevention strategies.

Nationwide sports injury prevention strategies: A scoping review

National strategies to prevent sports injuries can potentially improve health outcomes at a population level and reduce medical costs. To date, a compilation of the strategies that countries have attempted, and their effectiveness, does not exist. This scoping review sets out to: identify nationwide attempts at implementing sports injury prevention strategies; examine the impact of these strategies; and map them onto the Translating Research into Injury Prevention Practice (TRIPP) framework. Using Levac's scoping review method, we: (a) identified the research questions, (b) identified relevant studies, (c) identified the study selection criteria, (d) charted the data, and (e) reported the results. A search of MEDLINE, Scopus, SPORTDiscus, CINAHL, and Web of Science databases for articles published pre-June 2019 was conducted. We identified 1794 studies and included 33 studies (of 24 strategies). The USA (n = 7), New Zealand (n = 4), Canada (n = 3), the Netherlands (n = 3), Switzerland (n = 2), Belgium (n = 1), France (n = 1), Ireland (n = 1), South Africa (n = 1), and Sweden (n = 1) have implemented nationwide sports injury prevention strategies with 29 (88%) of the included studies demonstrating positive results. Mapping the strategies onto the TRIPP framework highlighted that only four (17%) of the 24 included strategies reported on the implementation context (TRIPP Stage 5), suggesting an important reporting gap. Nationwide sports injury prevention efforts are complex, requiring a multidimensional approach. Future research should report intervention implementation data; examine the implementation context early in the research process to increase the likelihood of real-world implementation success; and could benefit from incorporating qualitative or mixed research methods.

Citations Network Analysis of Vision and Sport

Background: Sports vision is a relatively new specialty, which has attracted particular interest in recent years from trainers and athletes, who are looking at ways of improving their visual skills to attain better performance on the field of play. The objective of this study was to use citation networks to analyze the relationships between the different publications and authors, as well as to identify the different areas of research and determine the most cited publication. Methods: The search for publications was carried out in the Web of Science database, using the terms "sport", "vision", and "eye" for the period between 1911 and August 2020. The publication analysis was performed using the Citation Network Explorer and CiteSpace software. Results: In total, 635 publications and 801 citations were found across the network, with 2019 being the year with the highest number of publications. The most cited publication was published in 2002 by Williams et al. By using the clustering functionality, four groups covering the different research areas in this field were found: ocular lesion, visual training methods and efficiency, visual fixation training, and concussions. Conclusions: The citation network offers an objective and comprehensive analysis of the main papers on sports vision.

Eye injuries in the National Hockey League from 2010 to 2018: an analysis of injury rates, mechanisms, and the National Hockey League visor policy

OBJECTIVE

We aim to assess the efficacy of widespread visor adoption by assessing eye injury rates during the 2010-2018 seasons. We also compare injury rates, missed games, and financial losses to previously reported data in order to track progress over time. Lastly, we characterize the mechanism and type of eye injuries sustained by National Hockey League (NHL) players to examine risk areas within NHL games.

DESIGN

We performed a retrospective review of NHL player injuries using official NHL team reports, ProSportsTransactions, and TSN Sports.

PARTICIPANTS

All NHL players who suffered an eye injury from 2010 to 2018 were included; 31 injuries matched this criterion.

METHODS

Trends in injuries, missed games, and financial losses over time were analyzed using Pearson's correlation coefficients. Wilcoxon-Mann-Whitney tests were performed to compare our data with eye injury data. Fisher's exact test was performed to assess significance between mechanism and type of eye injury and outcome.

RESULTS

There were 31 total eye injuries causing 233 missed games and a total of US$8 951 000 in financial losses across the 2010-2018 seasons. There was a strong decrease in the number of eye injuries (r = -0.83, p = 0.01) and a moderate decrease in number of missed games (r = -0.62, p = 0.09). Injuries due to direct puck strikes contributed to over US$6.5 million in financial losses and led to significantly more missed games compared with stick injuries (14.6 vs 4.3).

CONCLUSION

We tangibly demonstrate the financial and physical effects of recent safety interventions and indicate areas for improved safety in the NHL.

A systematic review of injuries in recreational field hockey: From injury problem to prevention

The purpose of this study was to gather information from scientific literature related to all steps of Van Mechelen's "sequence of prevention" for injuries applied to youth and adult recreational field hockey players. A systematic review was conducted in Medline via Pubmed and in SPORTDiscus via EBSCOhost. Twenty-six original studies were included. Regarding injury incidence (step 1) results showed several overall injury incidence rates (youth: 1.47 per 1,000 Athlete Exposure (AE) time-loss (TL) injury up to 11.32 per 1,000 AE TL ánd non-time loss (NTL) injury, adults: 2.2 NTL injury per 1,000 AE, 15.2 injury per 1,000 hours of sports participation). Considering games and practices, most injuries were sustained in games (youth: 4.9, adults: 7.87 per 1,000 AE). Considering body parts, highest injury incidence rates were found in body parts in the lower extremities (youth: knee injuries in games (0.33 per 1,000 AE), adults: hamstring injuries in pre-season (0.75 per 1,000 AE)) and injuries in the head/face/eye (youth: 0.66 and adults: 0.94 head/face/eye, 0.71 head/face and 0.63 concussion per 1,000 AE). Regarding aetiology (step 2), no studies were found. Regarding the efficacy of available interventions (step 3 and 4), one study was found among youth players, describing a warm-up programme.

Are high school girls' lacrosse players at increased risk of concussion because they are not allowed to wear the same helmet boys' lacrosse players are required to wear?

BACKGROUND

Boys' lacrosse (LAX), a full contact sport allowing body and stick checking, mandates hard shell helmets with full face masks. Girls' LAX, which prohibits body checking and whose sphere rule is supposed to prevent stick checking to the head, allows optional flexible headgear with/without integrated eye protection. Whether the required boys' LAX helmets should also be mandated in girls' LAX has been debated.

METHODS

In this retrospective cohort study we used LAX concussion data from a national high school sports-related injury surveillance study to determine if girls' LAX players were at increased risk of concussion from stick or ball contact due to differences in helmet regulations by calculating the attributable risk and attributable risk percent (AR%) for concussion resulting from ball or stick impacts.

RESULTS

From 2008-09 through 2018-19, boys' LAX players sustained 614 concussions during 1,318,278 athletic exposures (AEs) (4.66 per 10,000 AEs) and girls' LAX players sustained 384 concussions during 983,291 AEs (3.91 per 10,000 AEs). For boys, athlete-athlete contact was the most common mechanism of concussion accounting for 66.4% of all concussions, while stick or ball contact accounted for 23.5%. For girls, stick or ball contact accounted for 72.7% of all concussions, while athlete-athlete contact accounted for 19.8%. Concussion rates from stick or ball contact were significantly higher in girls vs. boys (RR = 2.60, 95% CI 2.12-3.18). The attributable risk associated with playing girls' vs. boys' LAX for concussion resulting from stick or ball contact was 1.75 concussions per 10,000 AEs (95% CI 1.37-2.12) and the AR% was 61.5% (95% CI 52.9-68.5). An estimated 44.7% of all girls' LAX concussions could have been prevented if girls' LAX players wore the helmet mandated in boys' LAX.

CONCLUSIONS

Girls' LAX players who are allowed, but not required, to wear a flexible headgear are at increased risk of concussions from stick or ball impacts compared to boys' LAX players, who are required to wear a hard shell helmet with full face mask. Additional research is needed to determine if there are any defendable arguments to continue justifying restricting girls' LAX players access to this effective piece of protective equipment.

Preventing injuries must be a priority to prevent disease in the twenty-first century

Injuries continue to be the leading cause of morbidity and mortality for children, adolescents, and young adults aged 1-24 years in industrialized countries in the twenty-first century. In this age group, injuries cause more fatalities than all other causes combined in the United States (U.S.). Importantly, many of these injuries are preventable. Annually in the U.S. there are >9 million emergency department visits for injuries and >16,000 deaths in children and adolescents aged 0-19 years. Among injury mechanisms, motor vehicle crashes, firearm suicide, and firearm homicide remain the leading mechanisms of injury-related death. More recently, poisoning has become a rapidly rising cause of both intentional and unintentional death in teenagers and young adults aged 15-24 years. For young children aged 1-5 years, water submersion injuries are the leading cause of death. Sports and home-related injuries are important mechanisms of nonfatal injuries. Preventing injuries, which potentially cause lifelong morbidity, as well as preventing injury deaths, must be a priority. A multi-pronged approach using legislation, advancing safety technology, improving the built environment, anticipatory guidance by clinical providers, and education of caregivers will be necessary to decrease and prevent injuries in the twenty-first century.

Intervention Strategies Used in Sport Injury Prevention Studies: A Systematic Review Identifying Studies Applying the Haddon Matrix

BACKGROUND

Prevention of sport injuries is crucial to maximise the health and societal benefits of a physically active lifestyle. To strengthen the translation and implementation of the available evidence base on effective preventive measures, a range of potentially relevant strategies should be considered.

OBJECTIVE

Our aim was to identify and categorise intervention strategies for the prevention of acute sport injuries evaluated in the scientific literature, applying the Haddon matrix, and identify potential knowledge gaps.

METHODS

Five electronic databases were searched (PubMed, EMBASE, SPORTDiscus, CINAHL, Cochrane) for studies that evaluated the effect of interventions on the occurrence of acute sport injuries. Studies were required to include a control group/condition, prospective data collection, and a quantitative injury outcome measure.

RESULTS

A total of 155 studies were included, mostly randomised controlled trials (43%). The majority of studies (55%) focussed on strategies requiring a behavioural change on the part of athletes. Studies predominantly evaluated the preventive effect of various training programmes targeted at the 'pre-event' phase (n = 73) and the use of equipment to avoid injury in the 'event phase' (n = 29). A limited number of studies evaluated the preventive effect of strategies geared at rules and regulations (n = 14), and contextual modifications (n = 18). Studies specifically aimed at preventing re-injuries were a minority (n = 8), and were mostly related to ankle sprains (n = 5).

CONCLUSIONS

Valuable insight into the extent of the evidence base of sport injury prevention studies was obtained for 20 potential intervention strategies. This approach can be used to monitor potential gaps in the knowledge base on sport injury prevention.

The First Decade of Web-Based Sports Injury Surveillance: Descriptive Epidemiology of Injuries in US High School Girls' Field Hockey (2008-2009 Through 2013-2014) and National Collegiate Athletic Association Women's Field Hockey (2004-2005 Through 2013-2014)

CONTEXT: 

The advent of Web-based sports injury surveillance via programs such as the High School Reporting Information Online system and the National Collegiate Athletic Association Injury Surveillance Program has aided the acquisition of data for girls' and women's field hockey injuries.

OBJECTIVE: 

To describe the epidemiology of injuries sustained in high school girls' field hockey in the 2008-2009 through 2013-2014 academic years and collegiate women's field hockey in the 2004-2005 through 2013-2014 academic years using Web-based sports injury surveillance.

DESIGN: 

Descriptive epidemiology study.

SETTING: 

Online injury surveillance from field hockey teams in high school girls (annual average = 61) and collegiate women (annual average = 14).

PATIENTS OR OTHER PARTICIPANTS: 

Girls' and women's field hockey players who participated in practices and competitions during the 2008-2009 through 2013-2014 high school academic years and the 2004-2005 through 2013-2014 collegiate academic years.

MAIN OUTCOME MEASURE(S): 

Athletic trainers collected time-loss (≥24 hours) injury and exposure data. Injury rates per 1000 athlete-exposures (AEs), injury rate ratios (IRRs) with 95% confidence intervals (CIs), and injury proportions by body site and diagnosis were calculated.

RESULTS: 

The High School Reporting Information Online system documented 983 time-loss injuries during 569 551 AEs; the National Collegiate Athletic Association Injury Surveillance Program documented 996 time-loss injuries during 185 984 AEs. The injury rate from 2008-2009 through 2013-2014 was higher in college than in high school (3.25 versus 1.73/1000 AEs; IRR = 1.89; 95% CI = 1.63, 2.18). Most injuries occurred during practices in high school (52.0%) and college (60.7%). Injury rates were higher during competitions than practices in high school (IRR = 2.00; 95% CI = 1.76, 2.26) and college (IRR = 1.96; 95% CI = 1.73, 2.23). At both levels, injuries most commonly occurred to the lower extremity and head/face and resulted in muscle/tendon strains and contusions. However, injury patterns varied between practices and competitions.

CONCLUSIONS: 

Injury rates and patterns varied across age groups and between practices and competitions, highlighting the need for development of targeted injury-prevention strategies at both levels of play.

Season and Sport-Specific Adolescent Concussions via Online Surveillance in New Jersey Public High Schools 2015–2017

Despite increased awareness of concussions among student-athletes, local epidemiologic surveillance efforts are limited, especially among adolescents. We analyzed data reported through a state public-school-based online surveillance tool during the fall (summer preseason and regular season), winter, and spring seasons of the 2015–2017 school years at seven participating public high schools across New Jersey. Concussions were sustained during interscholastic and intramural sports and in physical education classes. There were 208 concussions: 142 in fall (123 regular season), 22 in winter (21 regular season), and 44 in spring. Reports stated 75% were first concussions, but 17% were second and 2% were third concussions.

Concussion in field hockey: a retrospective analysis into the incidence rates, mechanisms, symptoms and recovery of concussive injuries sustained by elite field hockey players

Objectives

To identify the incidence and mechanisms of concussion in elite Field Hockey in different age groups and also the postconcussion symptoms and recovery times.

Methods

Data was collected retrospectively, for both training and matches, over a 12-month period from national level Field Hockey players across under-16, under-18, under-21, Development and Senior players.

Mechanism of injury (including player role and field position), postconcussive symptoms and recovery times were recorded following a semistructured interview with each player. Additional information on training hours, matches and squad size were also recorded in order to calculate the incidence per 1000 match hours.

Results

Of the 28 recorded cases, only 11 could be included in the study. Women had the highest incidence of concussion, with the majority being in the under-21 age group. Overall incidence varied from 3/1000 match hours in training to 0.02/1000 match hours in matches, with an overall incidence of 0–0.02/1000 match hours across all age groups. The most common mechanism of injury was collision with another player, followed by impact from a stick or ball Midfield and attacking forwards sustained the highest incidence of concussion. None of the concussed athletes wore protective headgear (there were no cases of concussion in goal keepers) and all occurred in open play rather than a penalty corner (when protective headgear is often worn). Postconcussion headaches and difficulty concentrating were the most commonly reported postconcussion symptoms. Average recovery time and return-to-play was 2–4 weeks.

Conclusions

Due to the low numbers, only limited conclusions can be made, but it would appear that the risk of concussion in elite Field Hockey is low. As age and skill increases, the risk decreases. Postconcussion symptoms and average return-to-play times are similar to other sports. From this study, no conclusions can be made as to the role of protective headgear to reduce the risk of concussion.

Eye Injuries in High School and Collegiate Athletes

Background:

Although eye injuries constitute a small percentage of high school and college sports injuries, they have the potential to be permanently debilitating.

Hypothesis:

Eye injury rates will vary by sport, sex, and between the high school and college age groups.

Study Design:

Descriptive epidemiology study.

Level of Evidence:

Level 3.

Methods:

Data from eye injury reports in high school and college athletes were obtained from the National High School Sports-Related Injury Surveillance System, High School Reporting Information Online (HS RIO) database over a 10-year span (2005-2006 through 2014-2015 school years) and the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) over an 11-year span (2004-2005 through 2014-2015 school years). Injury rates per 100,000 athlete-exposures (AEs), injury rate ratios (RRs), and 95% CIs were calculated. Distributions of eye injuries by diagnosis, mechanism, time loss, and surgery needs were also examined.

Results:

A total of 237 and 273 eye injuries were reported in the HS RIO and the NCAA ISP databases, respectively. The sports with the highest eye injury rates (per 100,000 AEs) for combined high school and college athletes were women’s basketball (2.36), women’s field hockey (2.35), men’s basketball (2.31), and men’s wrestling (2.07). Overall eye injury rates at the high school and college levels were 0.68 and 1.84 per 100,000 AEs, respectively. Eye injury rates were higher in competition than practice in high school (RR, 3.47; 95% CI, 2.69-4.48) and college (RR, 3.13; 95% CI, 2.45-3.99). Most injuries were contusions (high school, 35.9%; college, 33.3%) and due to contact (high school, 89.9%; college, 86.4%). Only a small percentage of injuries resulted in time loss over 21 days (high school, 4.2%; college, 3.0%).

Conclusion:

Eye injury rates and patterns vary by sport, sex, and between the high school and college age groups. Although severe injuries do occur, most eye injuries sustained by high school and college athletes are minor, with limited time loss and full recovery.

Clinical Relevance:

Additional focus needs to be placed on preventing eye injuries at the collegiate level in women’s and men’s basketball, women’s field hockey, and men’s wrestling.
