Final Comment: Return‐to‐Play Decision Making: Does Level of Competition Make a Difference?

The Role of Level of Play in Concussions in High School Athletes

OBJECTIVES

To examine level of play (LOP) as a risk factor for concussion severity and recovery-related outcomes among high school athletes, stratified by sex, and among boys, by sport (football, non-football male sports).

DESIGN/SETTING

Secondary analysis of data collected through the High School Reporting Information Online surveillance system for academic years 2007-2008 through 2018-2019.

PARTICIPANTS

A total of 9916 concussions were reported between the academic years 2007-2008 and 2018-2019 from 9 sports (5189 from football; 2096 from non-football male sports; 2631 from female sports).

MAIN OUTCOME MEASURE

Examined the association between LOP (Freshman, Junior Varsity [JV], and Varsity teams) and concussion outcomes (number of concussion symptoms, symptom resolution time [SRT], and time to return to play [RTP]).

RESULTS

Compared with Varsity football athletes, concussed JV football athletes had on average 0.19 fewer concussion symptoms, longer SRT (>1 week vs <1 week: odds ratio [OR] = 1.3; 95% confidence interval [CI], 1.1-1.5), and longer RTP (1-3 weeks vs <1 week: OR = 1.5; 95% CI, 1.2-1.9; >3 weeks vs <1 week: OR = 1.6; 95% CI, 1.1-2.3). Compared with Varsity football athletes, Freshman football athletes had on average 0.48 fewer concussion symptoms, longer SRT (OR = 1.3; 95% CI, 1.1-1.5), and longer RTP (1-3 weeks vs <1 week: OR = 1.5; 95% CI, 1.1-2.0; >3 weeks vs <1 week: OR = 2.0; 95% CI, 1.3-3.0). Similarly, compared with female athletes on Varsity teams, concussed JV female athletes had longer RTP (1-3 weeks vs <1 week: OR = 1.8; 95% CI, 1.2-2.7). Trend analyses revealed an increase in the number of concussion symptoms between 2015-2016 and 2018-2019, a decrease between 2009-2010 and 2018-2019 for SRT of less than 1 week, and an increase between 2014-2015 and 2018-2019 for RTP of less than 1 week among Varsity football athletes. Among Varsity female athletes, there was a linear decrease during the study period for RTP of less than 1 week.

CONCLUSIONS

Despite a higher number of symptoms overall and in recent years, Varsity football players had shorter RTP than Freshman and JV athletes.

Personal subjectivity in clinician discussion about retirement from sport post-concussion

BACKGROUND

There is increasing focus on the number of concussions after which an athlete should discontinue participating in contact or collision sports. This is a clinically subjective and, in some cases, a preference-sensitive decision.

PURPOSE

Our goal was to assess whether there is personal subjectivity in when athletic trainers (ATs) discuss the possibility of sport retirement post-concussion with athletes.

METHODS

A national sample of ATs who provide clinical care to college athletes completed a questionnaire (n = 677, 34% response rate). Structural equation modeling was used to assess the association between risk perceptions, risk tolerance, social influences (beliefs about athlete, coach and parent preferences), expectancies about athlete success (on and off field), and the number of concussions after which retirement would be discussed.

RESULTS

There was a significant direct effect of AT risk tolerance on the number of concussions after which sport retirement would be discussed, among both male and female ATs (male B = 0.54, p < 0.001; female B = 0.31, p < 0.001). ATs who more strongly prioritized athletes' on-field achievements indicated that they would discuss sport retirement after a larger number of concussions compared to their peers who less strongly valued athletic achievement.

CONCLUSIONS

The results suggest the potential utility of standardized approaches to communicating concussion risk consistently to athletes. This can help ensure that all athletes are uniformly able to make informed decisions about continued exposure to concussion risk that are based on their values and preferences.
