The NICA injury surveillance system: Design, methodology and preliminary data of a prospective, longitudinal study of injuries in youth cross country mountain bike racing

ObjectivesTo describe the design and implementation of an injury surveillance system for youth mountain bike racing in the United States, and to report preliminary first-year results. DesignDescriptive sports injury epidemiology study. MethodsAfter two and a half years of development and extensive beta-testing, an electronic injury surveillance system went live in January, 2018. An automated email is sent to a Designated Reporter on each team, with links to the injury reporting form. Data collected include demographic information, injured body part, injury diagnosis, trail conditions and other factors associated with injury occurrence. Results837 unique injuries were reported in 554 injury events among 18,576 student-athletes. The overall injury event proportion was 3.0%. The most common injury among student-athletes was concussion/possible concussion (22.2%), followed by injuries to the wrist and hand (19.0%). Among 8,738 coaches, there were 134 unique injuries reported that occurred in 68 injury events, resulting in an overall injury event proportion of 0.8%. The shoulder (38.2%) was the most commonly injured body part among coaches. Injuries among coaches tended to more frequently result in fractures, dislocations and hospital admission compared with injuries among student-athletes. Among student-athletes, female riders sustained lower limb injuries more than male riders (34.0% vs. 20.7%, p<0.001). ConclusionsA nationwide injury surveillance system for youth mountain bike racing was successfully implemented in the United States. Overall injury event proportions were relatively low, but many injury events resulted in concussions/possible concussions, fractures, dislocations and 4 weeks or longer of time loss from riding.

International Olympic Committee Consensus Statement: Methods for Recording and Reporting of Epidemiological Data on Injury and Illness in Sports 2020 (Including the STROBE Extension for Sports Injury and Illness Surveillance (STROBE-SIIS)).

Background:Injury and illness surveillance, and epidemiological studies, are fundamental elements of concerted efforts to protect the health of the athlete. To encourage consistency in the definitions and methodology used, and to enable data across studies to be compared, research groups have published 11 sport- or setting-specific consensus statements on sports injury (and, eventually, illnesses) epidemiology to date.Objective:To further strengthen consistency in data collection, injury definitions, and research reporting through an updated set of recommendations for sports injury and illness studies, including a new Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist extension.Study Design:Consensus statement of the International Olympic Committee (IOC).Methods:The IOC invited a working group of international experts to review relevant literature and provide recommendations. The procedure included an open online survey, several stages of text drafting and consultation by working groups, and a 3-day consensus meeting in October 2019.Results:This statement includes recommendations for data collection and research reporting covering key components: defining and classifying health problems, severity of health problems, capturing and reporting athlete exposure, expressing risk, burden of health problems, study population characteristics, and data collection methods. Based on these, we also developed a new reporting guideline as a STROBE extension—the STROBE Sports Injury and Illness Surveillance (STROBE-SIIS).Conclusion:The IOC encourages ongoing in- and out-of-competition surveillance programs and studies to describe injury and illness trends and patterns, understand their causes, and develop measures to protect the health of the athlete. The implementation of the methods outlined in this statement will advance consistency in data collection and research reporting.

INFLUENCE OF A PRE-SEASON COACHES’ EDUCATION WORKSHOP STRATEGY ON ATHLETE INJURY RISK ASSESSMENT

Background: Evidence-based preventive training programs (PTPs) used as a pre-participation warm-up for sport have been shown to reduce injury risk in youth athletes; however, injury risk improvements depend on PTP dosage and fidelity, where increased levels of PTP compliance facilitate and sustain greater reductions in injury risk. While coaches represent the best option to facilitate PTPs long term, it is unknown how to best train coaches to ensure effective PTP implementation behavior. In other areas of health behavior research, education strategies tailored specifically to an individual’s needs and interests increase the likelihood of adopting a given behavior. To encourage youth sport coaches to implement PTPs, it may be beneficial to tailor workshops. One way to gauge the impact of an education strategy is to look at end-user outcomes. Therefore, the purpose of this study was to evaluate changes in athlete injury risk, as measured by the Landing Error Scoring System (LESS), between adolescent basketball and soccer athletes whose coach attended a General pre-season education workshop on PTP implementation compared to a Tailored pre-season education workshop. Methods: A cluster randomized control trial was utilized. Youth soccer and basketball organizations were contacted to participate in a pre-season coaches’ education workshop on PTP implementation. Organizations were randomized into either a General or Tailored workshop. All participating coaches within a given organization attended the same workshop. General workshops contained standardized content including: youth sport injury epidemiology, injury rate and risk reduction benefits of PTPs, and hands-on instruction on how to implement a PTP. Coaches in Tailored workshops completed pre-workshop surveys. The pre-workshop survey contained Likert-style questions on knowledge of and experience with implementing PTPs. Researchers used the results to prioritize and inform content emphasis within the Tailored workshop. For example, if an organization had a high frequency of coaches who reported that they were particularly interested in the sport performance benefits of PTPs, the research team would devote increased time to discussing that particular component. Both the General and Tailored workshop were approximately 1-hour in length but varied in the amount of time spent on different topic areas. Athletes completed a PRE and POST season baseline assessment of injury risk. The injury risk assessment included three trials of a jump-landing task that was evaluated using the Landing Error Scoring System (LESS). The LESS is a valid and reliable clinical movement assessment used to identify high-risk movement patterns during a jump-landing task. LESS scores are based on observable errors, where a higher score indicates a greater number of movement errors and an increased risk of sustaining a lower extremity injury. To complete the task, participants jumped off a 30-cm high box to a distance half of their height and immediately rebounded straight in the air for maximum vertical height. A single, reliable rater graded all trials for PRE and POST. All three trials were averaged together for one composite LESS score at each time point. A mixed model analysis of variance (ANOVA) was used to evaluate differences in composite LESS score over time (PRE, POST) between educational workshops (General, Tailored). All data were analyzed using SPSS Version 21.0 with an a priori alpha level of p&lt;0.05. Results: Seventy-seven athletes on 9 teams across 6 different organizations (Coaches’ Workshops: General=5 teams from 4 organizations; Tailored=4 teams from 2 organizations) completed both PRE and POST testing sessions. There were no significant differences between workshop (General, Tailored) and LESS scores at POST (P&gt;0.05). Regardless of workshop LESS scores improved over time ((Mean±SD [95%CI]) Generalized PRE: 5.46±0.10 [4.84, 6.08], Generalized POST: 4.62±0.10 [4.00, 5.25], Tailored PRE: 5.99±0.09[5.40, 6.59], Tailored POST: 5.66±0.09[5.06, 6.25])(P=0.03). Conclusions: Regardless of coaches’ educational workshop strategy, athletes improved movement technique from PRE to POST across a single sport season. These findings suggest that any level of exposure to PTP-related content could have beneficial downstream effects for the end user, or in this case reduced injury risk for youth athletes. Future studies should look to evaluate the content of pre-season coach education workshops in conjunction with tracking fidelity of program delivery in order to optimize efforts to disseminate and implement PTPs for youth sport coaches.

Sex- and Sport-Specific Epidemiology of Cervical Spine Injuries Sustained During Sporting Activities

Although several investigations have examined the epidemiology of cervical spine injuries in sports, few studies have analyzed the nationwide incidence and sex-specific epidemiology of cervical spine injuries. The National Electronic Injury Surveillance System database, which collects information on patients presenting to the emergency department at 100 hospitals across the United States, was queried for neck sprains and cervical fractures associated with sporting activities from 2000-2015. A total of 26,380 neck sprains and 1166 fractures were identified. Compared with females, the incidence for injuries in males was 1.7 times greater for neck sprains and 3.6 times greater for fractures (P < 0.0001). Football was the most common cause of cervical sprains in males, followed by cycling and weightlifting/aerobics. Females sustained most neck sprains in weightlifting/aerobics, trampoline, and cheerleading. From 2000 to 2015, the incidence of neck sprains from aerobics increased from 15.5 to 25.3 per million person-years (P < 0.0001). Similarly, the incidence of cervical fractures from cycling increased from 0.67 to 2.7 per million (P < 0.0001). For males, cycling was the most common cause of fracture, followed by diving/swimming and football. For females, horseback riding was most common, followed by cycling and diving/swimming. Football is the leading cause of cervical sprains in the United States. The most common cause of cervical fracture in men is cycling, while in women it is horseback riding. The incidence of sport-related cervical fractures has increased by 35% from 2000 to 2015, which has been driven by an increase in cycling-related injuries.

An Updated Subsequent Injury Categorisation Model (SIC-2.0): Data-Driven Categorisation of Subsequent Injuries in Sport.

Accounting for subsequent injuries is critical for sports injury epidemiology. The subsequent injury categorisation (SIC-1.0) model was developed to create a framework for accurate categorisation of subsequent injuries but its operationalisation has been challenging. The objective of this study was to update the subsequent injury categorisation (SIC-1.0 to SIC-2.0) model to improve its utility and application to sports injury datasets, and to test its applicability to a sports injury dataset. The SIC-1.0 model was expanded to include two levels of categorisation describing how previous injuries relate to subsequent events. A data-driven classification level was established containing eight discrete injury categories identifiable without clinical input. A sequential classification level that sub-categorised the data-driven categories according to their level of clinical relatedness has 16 distinct subsequent injury types. Manual and automated SIC-2.0 model categorisation were applied to a prospective injury dataset collected for elite rugby sevens players over a 2-year period. Absolute agreement between the two coding methods was assessed. An automated script for automatic data-driven categorisation and a flowchart for manual coding were developed for the SIC-2.0 model. The SIC-2.0 model was applied to 246 injuries sustained by 55 players (median four injuries, range 1-12), 46 (83.6%) of whom experienced more than one injury. The majority of subsequent injuries (78.7%) were sustained to a different site and were of a different nature. Absolute agreement between the manual coding and automated statistical script category allocation was 100%. The updated SIC-2.0 model provides a simple flowchart and automated electronic script to allow both an accurate and efficient method of categorising subsequent injury data in sport.

Epidemiology of Overuse Injuries in Youth Team Sports: A 3-year Prospective Study.

Prospective studies on overuse injuries and their impact on athletic training among youth team sports are scarce. The purpose of this study was to investigate the incidence, severity and player related risk factors of overuse injuries among young (12-20 years) basketball and floorball players. A total of 387 players participated in a 3-year prospective study. Each player completed a baseline questionnaire regarding their background information. Overuse injuries that prevented players to fully or partly participate in their regular training were collected. In all, 204 overuse injuries were registered (injury incidence 1.51 injuries/1 000 h of exposure; 95% CI 1.35-1.78). Most of the injuries involved the knee (35%) and lower back (21%), and were classified as severe (44%). Injury incidence was 1.51 (95% CI 1.2-1.82) and 1.61 (95% CI 1.32-1.91) in basketball and floorball, respectively. Incidence was significantly higher among female compared with male players (incidence rate ratio 1.58; 95% CI 1.20-2.09). Previous injury and playing at adult level were the strongest factors associated with occurrence of an overuse injury. In conclusion, overuse injuries of the knee and low back are relatively common in youth basketball and floorball. Effective prevention strategies as well as training load monitoring is needed in youth team sports.

Combat Sports Injuries in Well-Trained Athletes during African Games 2015 in Brazzaville, Congo

The aim of this study was to analyze the epidemiology and distribution of combat sports injuries during African Games 2015. A retrospective study was conducted from November 2016 to February 2017, including all adult patients aged consulted by doctor during combat or admitted to emergency medical sport unit of complex sporting of these Games. The data collected were sex, time and day of consulting or admission, injury risk, types, location and causes of injuries. During these African Games, an average injury frequency of about 78.6% has been observed. Contusions (n = 104), sprains and luxations (n = 43), fractures (n = 40) and wounds (n = 12) were the main injuries observed among 187 athletes. The lower extremities were more frequently affected than the upper extremities (150 cases versus 78 cases). In conclusion, the present study provides the latest knowledge on the frequency and characteristics injuries in combat sports. Injuries are different according to sport in their mechanisms and injury distribution. During African competition and training session, the evaluation and prevention of these factors could decrease the occurrence of such injuries.

The Epidemiology of Injuries Across the Weight-Training Sports

Weight-training sports, including weightlifting, powerlifting, bodybuilding, strongman, Highland Games, and CrossFit, are weight-training sports that have separate divisions for males and females of a variety of ages, competitive standards, and bodyweight classes. These sports may be considered dangerous because of the heavy loads commonly used in training and competition. Our objective was to systematically review the injury epidemiology of these weight-training sports, and, where possible, gain some insight into whether this may be affected by age, sex, competitive standard, and bodyweight class. We performed an electronic search using PubMed, SPORTDiscus, CINAHL, and Embase for injury epidemiology studies involving competitive athletes in these weight-training sports. Eligible studies included peer-reviewed journal articles only, with no limit placed on date or language of publication. We assessed the risk of bias in all studies using an adaption of the musculoskeletal injury review method. Only five of the 20 eligible studies had a risk of bias score ≥75%, meaning the risk of bias in these five studies was considered low. While 14 of the studies had sample sizes >100 participants, only four studies utilized a prospective design. Bodybuilding had the lowest injury rates (0.12-0.7 injuries per lifter per year; 0.24-1 injury per 1000h), with strongman (4.5-6.1 injuries per 1000h) and Highland Games (7.5 injuries per 1000h) reporting the highest rates. The shoulder, lower back, knee, elbow, and wrist/hand were generally the most commonly injured anatomical locations; strains, tendinitis, and sprains were the most common injury type. Very few significant differences in any of the injury outcomes were observed as a function of age, sex, competitive standard, or bodyweight class. While the majority of the research we reviewed utilized retrospective designs, the weight-training sports appear to have relatively low rates of injury compared with common team sports. Future weight-training sport injury epidemiology research needs to be improved, particularly in terms of the use of prospective designs, diagnosis of injury, and changes in risk exposure.

Epidemiology Of Severe Injuries Within Ncaa Football, Wrestling, And Men’s Ice Hockey, 2009/10-2014/15 Academic Years.

Severe injuries are a challenge that many student-athletes endure throughout their collegiate participation in athletics. Current research focuses on severe injuries sustained during football. However, little research examines the epidemiology of severe injuries in other collision sports. PURPOSE: To describe the epidemiology of severe injuries sustained within collision sports (football, wrestling, men’s ice hockey) in the National Collegiate Athletic Association (NCAA) during the 2009/10-2014/15 academic years. METHODS: Severe injury data from the NCAA Injury Surveillance Program during the 2009/10-2014/15 academic years were analyzed. A severe injury was defined as: (1) occurring during a sanctioned competition or practice, (2) requiring medical attention by an athletic trainer or physician, and (3) resulting in time loss over 21 days or not returning for that sport season. Injury rates per 10000 athlete-exposures (AE) with 95% confidence intervals and distributions by body part, injury type, and injury mechanism were calculated. RESULTS: Overall, 1647 severe injuries occurred within collision sports. Severe injuries comprised 14.2% (n=173) of all injuries in wrestling, 10.3% (n=380) of all injuries in men’s ice hockey, and 10.2% (n=1094) of all injuries in football. The highest severe injury rate was in wrestling (1.65/10000AE), followed by football (0.97/10000AE), and men’s ice hockey (0.93/10000AE). Among severe injuries, the most common injured body part was the knee in football (40.6%, n=444) and wrestling (32.4%, n=56), and the head & neck in ice hockey (21.1%, n=80). The most common severe injury was ACL tear in football (14.0%, n=153), and concussion in wrestling (17.3%, n=30) and men’s ice hockey (18.4%, n=70). Concussions made up 10.6% of all severe injuries sustained within these sports. The most common injury mechanism was player contact in football (57.5%, n=629), wrestling (56.6%, n=98), and men’s ice hockey (49.7%, n=189). CONCLUSION: Severe injuries sustained in collision sports are often due to player contact and most often occur to the knee or head & neck. Additional research needs to help develop and evaluate injury prevention interventions to reduce injury incidence and severity in these sports.

Injuries in Swedish floorball: a cost analysis.

The epidemiology of sport injuries is well documented. However, the costs are rarely discussed. Previous studies have presented such costs in specific sports or localization. No study has investigated the costs related to injuries in elite floorball. Thus, the aim of this study was to estimate cost of injuries in Swedish elite floorball players. During 1year, 346 floorball players were prospectively followed. All time-loss injures were recorded. The injured players were asked to complete a questionnaire regarding their costs tied to the injury. Mean costs were calculated by multiplying the total resource use with the collected unit costs and dividing these total costs with the number of injuries as well as players. The results showed that the average cost per injury increased with the level of severity and ranged from 332 to 2358 Euros. The mild and moderate overuse injuries were costlier than the corresponding traumatic injuries. However, the severe traumatic injuries were associated with higher costs than overuse injuries. Knee injuries were the costliest. Our results indicate that there are costs to be saved, if floorball injuries can be avoided. They should be of interest to decision makers deciding whether to invest in preventive interventions.

Developing and Implementing Major League Baseball's Health and Injury Tracking System.

In 2010, Major League Baseball and the Major League Baseball Players Association reached an agreement regarding the development and implementation of an electronic medical record system and a new league-wide injury surveillance system. The systems were developed to create a more efficient method to track medical histories of players longitudinally as they move across Major and Minor league affiliates, as well as to identify and monitor injury trends in the sport, identify areas of specific concern, and conduct epidemiologic research to better optimize player health and safety. The resulting injury surveillance system, the Health and Injury Tracking System (HITS), is a robust system that includes all players from the both the Major and Minor Leagues. HITS also allows for data linkage with other player- and game-level data to inform the development of injury prevention policies and programs. In the present article, we document the development and implementation of HITS; describe its utility for epidemiologic research; illustrate the potential analytic strength of the surveillance system and its ability to inform policy change; and note the potential for this new surveillance system to advance the field of sports injury epidemiology.

Epidemiology of sports injuries referring to Kashan University of Medical Sciences Trauma Research Center from 2005 to 2011

ObjectiveAmong the injury types, sports ones constitute a considerable proportion of patients who refer to the medical centers. This research was conducted to examine the frequency of sports-related injuries referring to Kashan University of Medical Sciences Trauma Research Center from 2005 to 2011. MethodsThis was a retrospective research in which existing data from the data bank of Kashan University of Medical Sciences Trauma Research Center were employed. The data were extracted from the main source by SPSS version 16.0. Variables such as age, education, occupation and gender were analyzed. ResultsThe highest proportion of injuries was observed in students (59.4%) followed by workers (11.8%). Upper and lower extremities were most commonly injured. The most frequent injury was strain (35.4%), followed by sprain (27.7%). ConclusionThe results of this research showed that the majority of the sports trauma occurrs in students; therefore, they need more attention in regard to sports injuries. Preventive measures such as informing the coaches and teachers as well as increasing the students’ awareness about the injury risk can decrease the incidences of sports injuries.

The epidemiology of injuries in powerlifting at the London 2012 Paralympic Games: An analysis of 1411 athlete-days.

Sport injury epidemiology has received increased recognition as a field of sport medicine research that can improve the health and safety of athletes. Injuries among Paralympic powerlifters have not previously been systematically studied. The purpose of this prospective cohort study was to characterize injuries among Paralympic powerlifters. Athletes competing in the sport of powerlifting were followed over the 7-day competition period of the 2012 London Paralympic Games. The main outcome measurements were injury incidence rate (IR; number of injuries per 1000 athlete-days) and injury incidence proportion (IP; injuries per 100 athletes). A total of 38 injuries among 163 powerlifters were documented. The overall IR was 33.3 injuries/1000 athlete-days (95% CI 24.0-42.6) and the overall IP was 23.3 injuries per 100 athletes (95% CI 16.8-29.8). The majority of injuries were chronic overuse injuries (61%). The most commonly injured anatomical region was the shoulder/clavicle (32% of all injuries), followed by the chest (13%) and elbow (13%). The information obtained in this study opens the door for future study into the mechanisms and details of injuries into powerlifters with physical impairments.

Epidemiology of Aquatic and Recreational Water Sport Injuries: A Case-Control Analysis

The purposes of the current investigation are to evaluate the epidemiology of water sport injuries at a coastal tertiary trauma center and to determine the association of these activities with spinal column injury and to determine whether aquatic trauma injuries differ significantly from those that occur terrestrially. A retrospective review of a consecutive series of 105 patients with aquatic-based mechanisms of injury admitted to a Level II trauma center over a 3-year period, as well as a matched control cohort with terrestrial-based mechanisms of injury, was conducted. Patients were treated at a Level II trauma center from January 1, 2008, to December 31, 2010. All patients received a full trauma work-up on arrival. Patients were identified retrospectively from a prospectively collected database (N=5298). Eligible patients were identified from billing/coding data as having mechanisms of injury related to an aquatic setting. Patients were evaluated using standard trauma protocols. Spinal column and cord injury occurrence and differences between groups were reviewed. Personal watercrafts accounted for the majority of injuries (n=39). Cervical (33.3%), closed-head (25.7%), and thoracolumbar (21.9%) injuries accounted for the majority of injury types. The cervical spinal column and the spinal cord were at an increased risk of injury in the aquatic injury cohort (P<.0001). The current data show the high incidence of spinal column and cord injuries in this patient population relative to controls. Practitioners who care for trauma patients near an aquatic environment should be aware of the high prevalence of these injuries, with proper spinal cord preservation protocols in place to optimize outcome.

Epidemiology of sports injuries on collegiate athletes at a single center

OBJECTIVE: To evaluate the incidence of sports injuries in college athletes from the same institution from 1993 to 2013. METHODS: Athletes from 13 modalities were interviewed about the presence and type of injury, type of treatment and time of withdrawal, based on the questionnaire "Injury Surveillance System" (ISS). Data were analyzed with graphs and tables of injury prevalence by gender, age, site of injury and modality. We also analyzed the average time of withdrawal of athletes, returning to sports practice and new lesions. RESULTS: It was observed that 49.91% of the athletes showed some type of injury, with similar incidence between genders; the most frequent injuries were the anterior cruciate ligament (ACL) and the ankle sprain; the average withdrawal time was 11 weeks. ACL was the injury with greater impact on college sports career, especially given the time of withdrawal. CONCLUSION: The most frequent injury, ACL, occurred most frequently in indoor sports such as handball and volleyball and had the highest number of cases treated with surgery and a longer average withdrawal time. More studies are needed to create a larger database in order to schedule preventive measures for amateur athletes. Level IV of Evidence, Epidemiological Study.
