Sport Safety Policy Changes: Saving Lives and Protecting Athletes

Death during sport or physical activity is a tragic and unexpected event. However, with appropriate evidence-based policies in place, death can often be prevented. The top causes of sudden death in sport and physical activity are sudden cardiac arrest (SCA), exertional heat stroke (EHS), head injuries, and exertional sickling. Studies^1–3 suggest that more than 90% of sudden deaths in sport are attributable to these 4 causes, with SCA accounting for about 75% of sudden death during sport participation. Although sudden death from the aforementioned causes is not 100% preventable, the implementation of evidence-based safety policies such as emergency planning and access to automated external defibrillators (AEDs), heat acclimatization, instruction on proper tackling techniques (such as the “Heads Up Football” educational program), and sickle cell trait (SCT) screening in targeted populations can dramatically reduce overall risk. American football presents a unique risk profile for head injuries, EHS, and exertional sickling, which have driven many of the policy changes, but best practices for sport safety and emergency planning are relevant across all sports.

In 2012, the National Athletic Trainers' Association (NATA) released a position statement on the prevention of sudden death in athletes.⁴ Similarly, in 2013, the NATA released an interassociation task force document on preventing sudden death, specifically in the secondary school setting.⁵ The purposes of these documents were to provide evidence-based minimum best-practice recommendations to prevent, recognize, and treat the leading causes of death in sport and physical activity. To further focus efforts on preventing sudden death in the secondary school setting, the NATA, along with the American Medical Society for Sports Medicine and the Korey Stringer Institute, held the first annual “Collaborative Solutions for Safety in Sports” meeting in March 2015, at which a representative from each state's secondary school athletics association and a representative from each state's sports medicine advisory committee convened to discuss sport safety best practices and policy changes relevant to secondary school athletics. The second annual meeting in March 2016 will continue to provide state representatives with information and guidance for implementing evidence-based policies to protect their student-athletes.

HEAT ACCLIMATIZATION: AN EXAMPLE OF POLICY CHANGE THAT WORKS

In 2003, the National Collegiate Athletic Association (NCAA) implemented heat-acclimatization policies for preseason August football practices, requiring the phasing in of both activity and protective equipment during the hottest portion of the calendar year, when student-athletes are at highest risk of suffering EHS. Before heat-acclimatization policies were implemented, 1 or 2 EHS-related deaths occurred in NCAA student-athletes during August practices each year.¹ Implementation of heat acclimatization at the collegiate level has been hugely successful, reducing the total number of August EHS-related deaths to just 1 (total) since the 2003 policy- enactment date, a 95% reduction. This simple policy change that cost no money to implement has spared the life of an estimated 20 collegiate football players and has also likely reduced the number of instances in which an athlete survived EHS but had long-term complications. The NCAA heat-acclimatization policy is a great example of a policy change that can make a difference in student-athlete safety.

Casa et al,⁶ in 2009, published heat-acclimatization guidelines specific to high school athletes in an effort to reduce the number of deaths from EHS. Since 2011, 15 states have adopted heat-acclimatization policies as mandated by each state's high school athletics association (Figure). During high school preseason practices from 1980 to 2015 (a total of 488 preseasons), 22 of the 44 EHS deaths occurred in these 15 states before implementation of heat-acclimatization policies. Since implementation (a total of 50 preseasons), no student-athletes have died of EHS in these 15 states when schools followed the mandated heat-acclimatization guidelines. However, there was an EHS death at a Florida school in violation of state-mandated heat-acclimatization policies, thus emphasizing the importance of (1) implementing evidence-based heat-acclimatization policies for preseason practices and (2) complying with these policies to mitigate risk.⁷

SICKLE CELL TRAIT SCREENING LEADS TO INCREASED AWARENESS

In NCAA Division I collegiate football, the leading cause of death during training in the past decade has been an exertional sickling event in those with SCT.⁸ Division I collegiate football players with SCT are 37 times more likely to die during exertion than those without SCT.⁸ In response to an exertional sickling-related death of an athlete in 2006, the NCAA enacted a bylaw beginning August 1, 2010, at the Division I level, requiring all institutions to offer SCT identification through either screening or documentation of prior screening in all student-athletes. During the 2000–2001 through 2009–2010 academic years, 10 of 21 Division I collegiate nontraumatic football deaths were attributed to an exertional sickling episode (an average of 1.0 deaths/year).⁹ During the 2010–2011 through 2014–2015 academic years, nontraumatic exertional sickling-related deaths were significantly reduced, with only 1 of 14 deaths attributed to an exertional sickling episode. This suggests that a policy change fostering knowledge of SCT status in high-risk athletes, coupled with targeted education and tailored precautions, should be considered at other collegiate levels to reduce the risk of sudden death during participation for athletes with SCT.⁹

NO DEBATE: AEDS SAVE LIVES

Sudden cardiac arrest is the leading cause of sudden death in young athletes during sport and physical activity.¹⁰ Early recognition, early cardiopulmonary resuscitation (CPR), and prompt defibrillation are the key factors responsible for increasing survival after SCA. Survival rates decrease approximately 10% for each minute defibrillation is delayed,¹¹ and prior researchers^12–16 demonstrated an increase in survival when the time to defibrillation was minimized. Current consensus standards^5,17,18 for emergency preparedness in school and athletic settings recommend that an AED be readily available for use within 1–3 minutes to optimize the chance of survival after SCA. In a study¹⁴ of SCA on high school campuses, 89% of student-athletes who sustained SCA during exercise survived with prompt recognition and treatment. Thus, SCA in competitive athletes is largely a survivable event through immediate recognition, early CPR, and access to an AED, preferably within 1 minute.

For any athlete who has collapsed and is unresponsive, SCA should be assumed and the emergency action plan activated.⁷ Critical aspects of a comprehensive policy pertaining to SCA are (1) in every sport venue, easy access to an AED that can be retrieved and used within 1–3 minutes; (2) training of all medical staff, coaches, and other appropriate personnel in CPR and AED use and the location of AEDs; and (3) a sport-specific emergency action plan outlining the emergency response to an athlete or spectator who has collapsed that is rehearsed at least annually by all relevant persons and potential first responders.

THE CHALLENGE OF REDUCING HEAD INJURIES IN SPORT

With increasing scrutiny over head injuries and concussions in football players, steps have been and are currently being taken to address this concern through both education and practice modification. Recent research¹⁹ has shown the benefits of proper tackling education to reduce overall head impacts during American football. In addition, USA Football, the governing body for youth football, has been at the forefront of these efforts, launching its “Heads Up Football” program in 2012. The program was created with 6 pillars, or educational components, addressing tackling and blocking techniques, equipment fitting, and reducing player contact during practice, as well as SCA, exertional heat illness, and concussion.²⁰

Recent investigators²¹ examining injury rates in American youth football found a decline in all injuries, including concussion, when the “Heads Up Football” program and contact restrictions during practice were implemented. Injury rates during practices and games were significantly lower when both coaching education was provided and contact restrictions were enforced (0.97/1000 and 3.42/1000 athlete-exposures [AEs], respectively) compared with coaching education alone (2.42/1000 and 13.76/1000 AEs, respectively) or no coaching education or contact restrictions (7.32/1000 and 13.42/1000 AEs, respectively). When the authors examined types of injuries, coaching education and contact restrictions resulted in fewer injuries of all types, including concussions, than the other 2 groups. Establishing programs that offer proper education to coaches, players, and parents and implementing proper technique can create a safer environment for athletes at all levels.

THE PATH FORWARD

Although sudden death in sport cannot be completely prevented, establishing policies that conform to evidence-based best practices will reduce the overall risk of death and catastrophic injury. Medical professionals (eg, athletic trainers, physicians) should continue to work in conjunction with governing bodies—state high school athletics associations, the National Federation of State High School Associations, and youth sport governing bodies—to develop and implement appropriate policies for athletes at all levels of sport.
