INTRODUCTION
In 1931, the American Football Coaches Association (AFCA) initiated the First Annual
Survey of Football Fatalities and this research has been conducted at the University of North
Carolina at Chapel Hill since 1965. In 1977, the National Collegiate Athletic Association
(NCAA) initiated a National Survey of Catastrophic Football Injuries, which is also conducted at
the University of North Carolina. As a result of these research projects important contributions
to the sport of football have been made. Most notable have been the 1976 rule changes making it
illegal to make initial contact with the head and face while blocking and tackling, the National
Operating Committee on Standards for Athletic Equipment (NOCSAE) football helmet standard,
improved medical care for the participants, and better coaching techniques.
Due to the success of these two football projects the research was expanded to all sports
for both men and women, and a National Center for Catastrophic Sports Injury Research
(NCCSIR) was established in 1982. The decision to expand this research was based on the
following factors:
1. Research based on reliable data is essential if progress is to be made in sports safety.
2. The paucity of information on injuries in all sports.
3. The rapid expansion and lack of injury information in women's sports.
In 1987, a joint endeavor was initiated with the Section on Sports Medicine of the
American Association of Neurological Surgeons. The purpose of this collaboration was to
enhance the collection of medical data. Dr. Robert C. Cantu, Chairman, Department of Surgery
and Chief, Neurosurgery Service, Emerson Hospital, in Concord, MA, is the Medical Director of
the NCCSIR and has been responsible for evaluating the medical data. Dr. Cantu is also a Past-
President of the American College of Sports Medicine. The NCCSIR was directed for 30 years
by Dr. Frederick Mueller. Dr. Mueller retired in the Spring of 2013 and the NCCSIR continues
under new direction (Dr. Kucera). The NCCSIR has expanded to become a consortium of
universities (University of North Carolina, Boston University, University of Washington,
University of Connecticut, University of Colorado, University of Maryland) with expertise in
head/neck, cardiac, and heat-related sports medicine (these three areas account for the
overwhelming majority of catastrophic events).

METHODS
Outcome Definitions
For the purpose of this research the term catastrophic is defined as any severe injury
incurred during participation in a school/college sponsored sport. Catastrophic is divided into
the following three definitions:
1. Fatality
2. Non-Fatal - permanent severe functional disability.
3. Serious - no permanent functional disability but severe injury. An example would be
fractured cervical vertebra with no paralysis.
Sports injuries are also considered traumatic (or direct) or exertional/systemic (or
indirect). The definition for direct and indirect is as follows:
Direct - Those injuries that resulted directly from participation in the skills of the sport.
Indirect - Those injuries that were caused by systemic failure as a result of exertion
while participating in a sport activity or by a complication that was secondary
to a non-fatal injury.
Note: Beginning in 2014, NCCSIR also collects non sport-related injuries such as sudden
cardiac arrest that occurred outside of sport activity (e.g., during sleep). These events were not
included in the tables but are described in the Case Summary sections.
Data Collection
Data were compiled with the assistance of coaches, athletic trainers, athletic directors,
executive officers of state and national athletic organizations, online news reports, and
professional associates of the researchers. Data collection would not have been possible without
the support of the NCAA, the National Federation of State High School Associations (NFHS),
NCCSIR All Sport Report 1982/83-2017/18 3
and the AFCA. Upon receiving information concerning a possible catastrophic sports injury,
contact by telephone, email or personal letter and questionnaire was initiated with the injured
player's athletic trainer, athletic director, or coach. Data collected included background
information on the athlete (age, height, weight, experience, previous injury, etc.), accident
information, immediate and post-accident medical care, type injury, and equipment involved.
Autopsy reports are used when available. In order to improve overall capture of catastrophic
sport injury and illness events, NCCSIR and the Consortium for Catastrophic Injury Monitoring
in Sport developed an online portal where anyone can report a catastrophic event:
https:\\www.sportinjuryreport.org. The portal was activated in January 2015.
Participation in Sport
Yearly participation estimates for high school athletes are obtained from NFHS
participation reports (available online:
https://www.nfhs.org/ParticipationStatistics/ParticipationStatistics/). NFHS high school annual
athletic participation for 2017/18 included 7,677,337 athletes (4,421,063 males and 3,256,274
females). Yearly participation estimates for collegiate level athletes are obtained from the
National Collegiate Athletic Association (NCAA) participation reports (accessed online:
https://ncaaorg.s3.amazonaws.com/research/sportpart/Oct2018RES_2017-
18SportsSponsorshipParticipationRatesReport.pdf). NCAA participation for 2017/18 in
championship sports was 494,992 athletes. There were 278,614 males and 216,378 females.
There were also 3,314 males in non-championship sports (archery, badminton, bowling,
equestrian, rowing, rugby, sailing, and squash) and 2,427 females participating in emerging
sports (archery, badminton, equestrian, rugby, squash, synchronized swimming, team handball,
and triathlon).
During the entire 35 year period from the fall of 1982 through the spring of 2018, there
were 228,610,552 high school participant-seasons in the sports covered by this report and
approximately 13,069,182 college participant-seasons (Table 12).
Not all high schools and colleges are members of the NFHS and NCAA. Complete data
is not available for the non-member schools. Therefore, these participation numbers
underestimate the total number of high school and collegiate participants in the United States.
NCCSIR All Sport Report 1982/83-2017/18 4
Analysis
Frequencies and incidence rates of catastrophic injury per 100,000 participants were
calculated over the entire 36-year period and stratified by level (high school and college) and
sport. Incidence rates were stratified by direct versus indirect and by severity. Note: if there
were no events in the sport for a particular year, the year is excluded from the frequency
Table. Rates with number of incidents less than 5 should be interpreted with caution.
It is important to note that information is continually being updated due to the fact that
catastrophic injury information may not always reach the NCCSIR in time to be included in the
current final report. The report includes data that is reported to the NCCSIR by the NCAA, the
NFHS, online reports, colleagues, coaches, and athletic trainers. There may be additional
catastrophic injuries that are not reported to the NCCSIR. The authors acknowledge that not
every catastrophic injury is included in this report.
RESULTS
Current AY2017-2018 Summary
From July 1, 2017 to June 30, 2018 there were a total of 99 catastrophic injuries/illnesses
captured by NCCSIR among high school and college organized sport participants. Of these, 85
events were due to or occurred during sport-related activities (Table 11). There were also 14
catastrophic events that occurred during non-sport related activity. All were cardiac-related.
Sport-related events: The majority of the sport-related catastrophic events (n=85) were at the
high school level (78%, n=66). Member institutions for collegiate cases included NCAA and
National Association of Intercollegiate Athletics (NAIA). Overall 24.7% of cases were fatal,
9.4% were nonfatal, 60.0% were serious with recovery, and 5.9% were unknown. Forty-six
percent (n=39) were due to direct (traumatic injury) causes and over half occurred in competition
(50.6%) followed by practice (29.4%). The majority of events occurred to athletes participating
in the following sports: football (54.1%), basketball (15.3%), soccer (9.4%), baseball (4.7%),
cross country (3.5%), lacrosse (3.5%), track and field (2.4%), wresting (2.4%), swimming
(2.4%), cheerleading (1.2%) and ice hockey (1.2%). Areas of the body most commonly affected
NCCSIR All Sport Report 1982/83-2017/18 5
were heart (38.8%), spine (21.2%), and head/brain (15.3%). Sudden cardiac arrest (38.8%) was
the most common types of events followed by brain trauma (14.1%) and other traumatic injuries
(9.4%).
Direct events: 12.8% of direct events were fatal, 20.5% non-fatal, 53.8% serious with recovery,
and 12.8% unknown. A greater proportion of direct events occurred in competition versus
practice (69.2% versus 25.6%) and were due to contact with another player (56.4%) or
apparatus/object (12.8%). The highest proportion was to the spine (46.2%) and head/brain
(33.3%) followed by other traumatic injury (15.4%) and commotio cordis (5.1%). The majority
occurred in football (79.5%) followed by soccer (5.1%) and baseball (5.1%).
Indirect events: 34.8% of indirect events were fatal and 65.2% were serious with recovery.
Similar proportions of indirect events occurred in competition and practice (34.8% versus
32.6%) and 10.8% occurred during conditioning and weight training sessions. The majority
were cardiac-related (71.7%), followed by heat related (15.2%) and rhabdomyolysis and other
(2.2% each). Football (32.6%) and basketball (28.3%) comprised the majority, followed by
soccer (13.0%) and track and field, baseball, lacrosse, cross country, and swimming (4.3% each).
Overall Summary
During this 36-year period, there were 2,686 catastrophic sport-related injuries/illnesses at high
school and college levels (Table 1 – excluding cheerleading, drill team, and rodeo there were
2,566). The majority were non-fatal (64%) and from traumatic or direct mechanisms (65%), and
among high school participants (79%). The proportion of fatal (38% versus 35%) and direct
(65% versus 62%) were not different by high school compared to college level.
The 85 sport-related catastrophic injuries and conditions captured in 2017/18 is not different
from the previous year (80 in 2016/17) and a 26% decrease from 2015/16—a result of a lower
number of traumatic brain and cervical spine/spinal cord injuries in 2017/18 and 2016/17. Note:
see limitations regarding the interpretation of this percentage difference.
NCCSIR All Sport Report 1982/83-2017/18 6
Traumatic Injuries (Direct) by Sport: For high school sports, football had the highest number of
traumatic injuries (direct) catastrophic events, followed by female cheerleading, wrestling,
baseball, and male track and field (Table 4a). Accounting for the number of participants in the
sport, male and female cheerleading, male gymnastics, football, and male ice hockey had the
highest rates per 100,000 participants (Figure 2, Table 9a). Similar results were observed when
restricted to fatal events (Figure 1).
For college sports, football had the highest number of traumatic injuries (direct) catastrophic
events, followed by female cheerleading, baseball, and male track and field (Table 5a).
Accounting for the number of participants in the sport, male gymnastics, female skiing, football,
male ice hockey, male skiing, equestrian and female gymnastics had the highest rates per
100,000 participants (Figure 4, Table 9b). Similar results were observed when restricted to fatal
events (Figure 3).
Exertional and Systemic Conditions (Indirect) by Sport: For high school sports, football had the
highest number of exertional and systemic (indirect) catastrophic events, followed by male
basketball, male track and field, male soccer, wrestling, baseball, and male cross country (Table
4b). Accounting for the number of participants in the sport, rowing, male basketball, football,
male ice hockey, male water polo, and male lacrosse had the highest rates per 100,000
participants (Figure 2, Table 10a). Similar results were observed when restricted to fatal events
(Figure 1).
For college sports, football had the highest number of exertional and systemic (indirect)
catastrophic events, followed by male basketball, wrestling, female basketball, baseball, male
soccer, and male swimming (Table 5b). Accounting for the number of participants in the sport,
male basketball, male water polo, male skiing, football, male wrestling, male ice hockey, male
swimming, and male rowing had the highest rates per 100,000 participants (Figure 4, Table 10b).
Similar results were observed when restricted to fatal events (Figure 3).

DISCUSSION
The following strengths and limitations should be noted:
Data have been collected by The National Center for Catastrophic Sport Injury Research
for all high school and college sports since 1982 using consistent definitions and
methodology over a 30+ year period. These data are provided annually to sport
organizations (NCAA, NFHS, AFCA), researchers and the public. Sports medicine
advisory committees, sport rules committees, and coaching committees review the reports
and have used these data to inform and evaluate safety recommendations, medical care,
and rule changes.
Catastrophic events are primarily captured through publicly available media reports.
Therefore, not all catastrophic events are captured. Particularly, for non-fatal
catastrophic events, which may not be reported in the media as comprehensively as
fatalities. Under-reporting may also be due to outcome definitions used (e.g. timing of
the event) and event locations (e.g. at home, personal conditioning). In order to
improve overall capture of these events, NCCSIR and the Consortium for
Catastrophic Injury Monitoring in Sport have developed an online portal where
anyone can report a catastrophic event: https:\\www.sportinjuryreport.org. The
online portal was activated in January 2015. Any observed changes in annual number of
events may be attributed to these described improvements in data collection methods.
Details surrounding catastrophic events that are only captured through publicly available
media reports may not be completely accurate in the absence of the actual autopsy or
medical reports.
Incidence rates were calculated using participation estimates from NFHS and the NCAA
in the rate denominator (Table 12). These participation estimates do not include schools
that are not members of these two associations. Participation data were not available for
these non-member schools. At present NFHS and NCAA are the only estimates
available. Therefore, the participation numbers (rate denominator) in this report are
underestimated, which results in an overestimate of the actual incidence rate.
It is important to note that catastrophic events are rare and statistical power for some
strata comparisons are limited. Rates with number of incidents less than 5 should be
interpreted with caution.
NCCSIR All Sport Report 1982/83-2017/18 8
RECOMMENDATIONS
1. Each athlete should have a complete physical examination with a medical history and an
annual health history update.
2. All personnel involved with training athletes should emphasize proper, gradual, and sport-
specific physical conditioning.
3. Every school should strive to have a certified athletic trainer.
4. Each school should have a written emergency action plan (EAP) in place, all personnel
should have copies, and procedures should be reviewed and practiced annually.
The Centers for Disease Control and Prevention (CDC) has guidelines and templates
for these plans (http://www.cdc.gov/niosh/docs/2004-101/emrgact/emrgact1.html).
NCAA and the NFHS have guidelines for these plans at the following websites:
www.nfhs.org and www.ncaa.org.
An automated external defibrillator (AED) should be available and accessible
onsite and medical and coaching staff should be trained in the use.
5. There should be an emphasis on employing well trained athletic personnel, providing
excellent facilities, and securing the safest and best equipment available.
6. There should be strict enforcement of game rules and administrative regulations to protect
the health of the athlete and reduce the risk of catastrophic injury. Coaches and school
officials must support the game officials in their rulings during the sporting event.
7. Coaches should be educated on and have the ability to teach the proper fundamental skills
of the specific sport. Specific to football, the proper fundamentals of blocking and
tackling should be emphasized to help reduce head and neck injuries, especially with
keeping the head out of blocking and tackling.
8. Weight loss in wrestling to make weight for a match can be dangerous and cause serious
injury or death. Coaches should be aware of safety precautions and rules associated with
this practice.
9. There should be continued surveillance and safety research in athletics (rules, facilities,
equipment, medical care and procedures).
10. Sudden cardiac arrest: The number of exertional and systemic (indirect) cardiac related
events has increased over the years and it is recommended that schools have and
emergency action plan and automated external defibrillators (AED) available and
NCCSIR All Sport Report 1982/83-2017/18 9
accessible on-site for emergency situations. Early detection and defibrillation is critical
for survival (3-5 minutes recommended). (Casa et al. 2012)
See also Drezner et al. 2007 for additional information about sudden cardiac arrest
preparedness and management: http://www.nata.org/sites/default/files/sudden-
cardiac-arrest-consensus-statement.pdf
11. Heat-illness: All personnel associated with sport participation should be cognizant of the
safety measures related to physical activity in hot weather. Heat stroke and heat
exhaustion are prevented by careful control of various factors in the conditioning program
of the athlete.
The NATA has a heat illness position statement on their web site
(https://www.nata.org/news-publications/pressroom/statements/position) with
recommendations for prevention: Casa et al. 2015
(http://natajournals.org/doi/pdf/10.4085/1062-6050-50.9.07) and Casa & Cisllan,
2009 (http://natajournals.org/doi/pdf/10.4085/1062-6050-44.3.332)
Coaches, athletic trainers, and players should refer to the multiple published best
practices by the NATA, American College of Sports Medicine (ACSM), NFHS, and
NCAA on preventing and managing heat illness. Emergency action plans should be
activated.

EHS-September-2017.pdf
12. Head Trauma: When a player has shown signs or symptoms of head trauma (such as a
change in the athlete’s behavior, thinking, or physical functioning), the player should
receive immediate medical attention from an appropriate medical provider and should not
be allowed to return to practice or game that day. The athlete should not be allowed to
return to practice or game without an evaluation by an appropriate medical provider.
NCCSIR All Sport Report 1982/83-2017/18 10
All athletes and athletic personnel should follow the state, NFHS, and NCAA policies
related to concussion and return to play. See the following CDC resource for a list of
states and their concussion policies: https://www.cdc.gov/headsup/policy/index.html
For the most up to date information on concussion management please see the
updated Consensus Statement on Concussion in Sport: The 5th International
Conference on Concussion in Sport held in Berlin, October 2016 (McCrory et al.
2017 available at http://bjsm.bmj.com/content/51/11/838).
Some cases associated with brain trauma reported that players complained of
symptoms or had a previous concussion prior to their deaths. The team physician,
athletic trainer, or coach should ensure players understand signs and symptoms of
concussion and brain trauma. Players should also be encouraged to inform the team
physician, athletic trainer, or coach if they are experiencing any of the signs or
symptoms of brain trauma outlined by the CDC.
HEADS UP ON CONCUSSION IN SPORTS:
Information for Parents, Coaches, and School & Sports Professionals. Available at:
http://www.cdc.gov/headsup/highschoolsports/index.html
The NFHS Sport Medicine Advisory Committee has developed guidelines for concussion
management in sports: http://www.nfhs.org/media/1014737/suggested-guidelines-for-
management-of-a-concussion-in-sports-october-2013-2.pdf
The NCAA has created several rules to help manage concussion injuries. The NCAA has
created a set of best practices that are available in the Sports Medicine Handbook which may
be found at: http://www.ncaapublications.com/
Every NCAA member school is required to have a concussion-management plan that:
Requires student-athletes to receive information about the signs and symptoms of
concussions. They also are required to sign a waiver that says they are responsible for
reporting injuries to the medical staff.
Mandates that institutions provide a process for removing a student-athlete from
play/participation if they exhibit signs of a concussion. Student-athletes exhibiting
signs of a concussions must be evaluated by a medical staff member with experience
in the evaluation and management of concussions before they return to play.
NCCSIR All Sport Report 1982/83-2017/18 11
Prohibits a student-athlete with concussion symptoms from returning to play on the
same day of the activity.
Requires student-athletes diagnosed with a concussion be cleared by a physician
before they are permitted to return.
13. Spinal injuries: Early recognition, prompt medical evaluation and management of
cervical cord and spine injuries is critical for preventing permanent disability and death.
Certified athletic trainers are trained to recognize and manage these injuries and whenever
possible should be present for all football practices and games. For the most up to date
information on management and prevention of these injuries see the following websites:
National Athletic Trainers Association: https://www.nata.org/practice-patient-
care/health-issues/spine-injury
Kory Stringer Institute: https://ksi.uconn.edu/emergency-conditions/cervical-spine-
injury/
See also Swartz et al. 2009 for information about cervical spinal injury management
and prevention:
http://www.nata.org/sites/default/files/AcuteMgmtOfCervicalSpineInjuredAthlete.pdf
14. Internal Organ Injuries: Like cervical cord and spinal injuries, early recognition and
prompt medical evaluation and treatment of internal organ injuries is critical for ensuring
the best possible outcome. Emergency action plans, access to certified athletic trainers,
and on-site medical services for competitions constitute best practices for these injuries.
A better understanding of the activities and mechanisms associated with these injuries
and use of protective gear worn is needed for prevention. Wearing protective gear (e.g.,
padded belt or shirt) that extends beyond the bottom of the shoulder pads to cover the
torso may protect internal organs from direct contact.

CASE SUMMARIES AY2017/18
*Compiled from available media reports (n=85 events captured by NCCSIR).
COLLEGE/UNIVERSITY
Collegiate/University Baseball Indirect
A male 17 year old college sophomore baseball player collapsed at home after finishing a
personal workout from hypertrophic cardiomyopathy. He was surrounded by teammates who
began CPR until EMS arrived. After being hospitalized, he underwent a heart transplant. A full
recovery is expected. He has been diagnosed with the cardiac condition a few years prior but was
taking medication and cleared to play baseball.
A male 18 year old collegiate sophomore baseball player collapsed while helping coach a
baseball practice. He was throwing pitches in the bullpen when he collapsed. The team's head
coach immediately started CPR and continued until EMS arrived. He received three AED shocks
during transport to a hospital. He had a defibrillator implanted and a full recovery is expected.
Collegiate/University Basketball Indirect
A male college senior basketball guard collapsed during a game while sitting on the bench from
sudden cardiac arrest. He was immediately attended to by the athletic trainer who began CPR
while EMS were called. He was revived with an AED. He was transported to the hospital where
he underwent surgery to have a defibrillator implanted. Full recovery is expected.
A male 20 year old college junior basketball player collapsed during a scrimmage game. He was
revived by coaches and AED before EMS arrived. He was transported to the hospital where he
was diagnosed with hypertrophic cardiomyopathy. He underwent surgery to have a defibrillator
implanted. A full recovery is expected but he can no longer play basketball.
Collegiate/University Football Direct
A male 22 year old college football quarterback sustained an injury when an opposing player fell
on him during a football game. Athlete kept playing until sustaining a mild concussion later in
the game. He went to the hospital where he was diagnosed with a lacerated spleen causing
