Abstract

Objective To determine the impact of socioeconomic status (SES) on outcomes after sport-related concussion (SRC) in a regional sports concussion centre.

Design Retrospective cohort study.

Setting Comprehensive sports concussion centre.

Participants 282 youth, high school, and collegiate student-athletes.

Intervention All patients seen at a comprehensive sports concussion centre were contacted after their injury for in-depth telephone interviews. Subsequent demographic data was also collected.

Outcome measures SES was defined based on six variables: cost of living percentile, median income percentile, % college graduates, % homeowners, county type, and insurance. Outcomes after SRC were defined as the following three variables: days of symptom duration, days of missed school, and days of missed practice.

Main results A total of 282 student-athletes were studied. The median age was 15.8 years (range 11.6–22.2). American football was the most common sport (32.2%). After multivariate cox-regression analysis, no relationship between SES and symptom duration or missed practice was seen. For the outcome of missed school, insurance status had a significant relationship, where those with private insurance had fewer missed days of school than those with public insurance (HR 0.46, 95% CI: 0.26–0.83, p=0.009).

Conclusions In a regional cohort of youth, high school and collegiate student-athletes, SES had largely no impact on the outcomes of symptom duration, missed school, and missed practice. The only significant relationship was that those with private insurance returned to school quicker than those with public insurance, which may represent increased access to rehabilitation resources after SRC.
