BACKGROUND
1) Historical evidence that a substantial number of
SRCs may go unreported.
2) Athlete’s recovering from SRCs may be allowed to
return to sports prematurely without proper
medical supervision
3) No large-scale studies in Wisconsin on the
incidence, impact and management practices for
SRCs in high school athletes.
1) Determine the level of AT employment
in WI high schools
2) Secure research funds
3) Collect SRC incidence and
management information in WI schools
with different levels of AT availability
A Multi-Step Process
FIRST STEPS
1) 2015 - Research grant
“Utilization of athletic trainers in high school settings.”
2) Survey School AD’s and ATs who may work in high schools
settings
a) Employer (if not the school district)
b) Contract
c) Coverage details
The First Step
Wisconsin AT Availability
1) > 95% had access to an AT
2) Availability and services performed
varied considerably
3) School enrollment was not correlated
with AT availability
4) Compare SES and AT availability

The Impact of Athletic Trainers on the Incidence and
Management of Concussions in High School Athletes
RESEARCH PLAN
Plan: Assign schools to 1 of 3 groups based on their AT access
1) High-level of AT availability (HiAT)
2) Mid-level availability (MidAT)
3) Low-level AT availability (LoAT)
Specific Aim 1: To compare the incidence of SRCs
Specific Aim 2: To compare SRC management practices
Specific Aim 3: To determine the health outcomes (symptoms,depression and HRQoL) in subjects with SRCs
Study Aims
Research Overview
Design: Prospective cohort study.
Participants: 2200+ athletes from 30 high
schools
Interventions: Self-report measures of: 1) quality
of life, 2) depression and 3) SRC symptoms
ATs record all SRC injuries that occur during the
sport seasons.
SRC’s complete baseline measures at various
time points up to one year post injury.
Analyses: logistic regression model followed by a
multivariate Cox-PH model.
AT / School Scenarios
#1 Enrollment: 240, Fall participants: 70
AT: 0.5 - 1.0 hrs. / week
#2 Enrollment: 620, Fall participants: 130
AT: 25 - 35 hrs. / week
#3 Enrollment: 1560, Fall participants: 582
AT: 30 - 35 hrs. / week
#4 Enrollment: 1210, Fall participants: 380
AT: 75 - 90 hrs. / week
AT availability = number of athletes the AT was
expected to serve per hour (athletes/AT hour).
HiATC (= < 20.0 athletes/AT hour)
MidATC (20.0 – 40.0 athletes/AT hour)
LoATC (= > 40.0 athletes/AT hour)
Analyses For
1) SRC Incidence
2) Time until examined by AT
3) Parent Contact
4) Coach Contact
5) # of Post SRC Evals
6) Days out from sport

CONCLUSIONS
AT availability in schools was associated with various rates
of recognized SRCs and post-SRC management actions
Given the significant public health burden SRCs impose…..
Sufficient AT availability is crucial to rapidly identify, assess
and manage these injuries

SRC Injury Definition
SRC will be defined according NATA as a: ‘‘trauma induced alteration in mental status that
may or may not involve loss of consciousness.’’ This alteration may include the rapid onset
of short-lived impairment of neurological function and may involve one or more of the
following symptoms: headache, nausea, vomiting, dizziness/balance problems, fatigue,
difficulty sleeping, drowsiness, sensitivity to light/noise, blurred vision, memory difficulty,
and difficulty concentrating.
Specifically, an injury must meet both of the following criteria:
1) Occurred as a result of participation in
interscholastic sport practice or competition.
2) Required medical attention and or treatment
by the school AT or licensed primary care
provider (MD, NP, PA etc.) before the subject
was allowed to return to sport.
SRCs will be excluded if they did not occur during interscholastic sport participation.
