To examine return-to-play (RTP) practice differences between high school and collegiate athletes, as well as the stability (i.e., year-by-year) in these practices over a 5-year period. We hypothesized that similar protocols for treatment will be comparable across competition levels and that these practices will vary year-to-year. Prospective cohort study. Nine high schools and four National Collegiate Athletic Association Division III colleges in southeastern Wisconsin. Two-hundred and seventy-three (N=273) athletes with sport-related concussions (SRCs). Independent predictors included competition level (high school, n=88 vs. collegiate, n=185) and year-of-injury. Athletes were evaluated prospectively for differences in symptom duration, symptom free waiting period (SFWP), and time to RTP, as well as longitudinal changes in management. High school and collegiate athletes experienced comparable median symptom duration (high school, 6.0 days, IQR=3.5–11.0; college, 6.0 days, IQR=4.0–9.0, P=0.95), SFWP (high school, 5.0 days, IQR=3.0–8.0; college, 5.0 days, IQR=3.0–7.0, P=0.12) and total time to RTP (high school, 10.5 days, IQR=7.0–16.0; college, 11.0 days, IQR=8.0–14.0 days, P=0.94). A Cox regression analysis revealed a non-significant trend towards longer SFWPs in high school athletes (P=0.055; HR=1.347, CI=0.99, 1.83). Among football players, SFWPs in 2017 (Median=3.5 days, IQR=1.5–5.0 days) were significantly longer compared to 2014 (Median=5.0 days, IQR=4.0–8.5 days, P=0.029) after correction for multiple comparisons. Similar post-injury and RTP management practices were observed at the high school and collegiate levels following SRC. Symptom duration and time from injury to unrestricted RTP were comparable, although high school athletes may have longer SFWPs.
