Sport-related concussion (SRC) in the primary care setting is understudied.

PURPOSE: This study describes the epidemiology and gender differences of young SRC patients presenting to the primary care setting.

METHODS: This was a prospective cohort presenting to 3 clinics of a large urban/suburban practice group from December 19, 2015-October 10, 2015. Included were patients 8-18 years, presenting within 3 days of a SRC, who consented to participate. Certified athletic trainers completed data collection at the initial visit. Participants completed a standardized initial concussion visit, including a clinical exam, a symptom checklist, the Immediate Post-Concussion and Cognitive Test (ImPACT), and a visual-vestibular screening. T-tests and Chi-Square analyses were used to examine gender differences.

RESULTS:A total of 131 patients were included: 75 (57.3%) were male, 101 (77.1%) Caucasian, 17 (13.1%) were injured in football, 16 (12.2%) had ADHD, 7 (5.4%) had a history of a psychological disorder, and 46 (35.1%) had a prior history of head trauma. Emergency department visits preceded the clinic visit for 19 (14.5%) patients and 10 (7.6%) patients had imaging for their SRC. There were 10 (7.6%) with loss of consciousness and 16 (12.2%) with amnesia post-injury. Mean age was 14.3±2.0 years. Mean symptom severity was 27.3±21.2. Mean ImPACT composites scores for patients clinically able and within the appropriate age range (n=123) were: Verbal Memory=81.8±12.4, Visual Memory=71.8±13.9, Reaction Time=1.0±3.6; and Processing Speed=33.7±8.1. Thirty-seven (28.2%) patients had abnormal near point convergence (>5cm). Females (Symptom Total=34.1, 95% CI: 27.4-40.8) reported a significantly greater symptom burden than males (Symptom Total=22.9, 95% CI: 19.2-26.7). Females also scored slightly lower on Verbal Memory (Female=78.7, 95% CI:75.3-82.0; Male=83.2, 95% CI: 80.0-86.3) and Visual Memory (Female=68.8, 95% CI: 65.2-72.4; Male=73.8, 95% CI: 70.4-77.3). No other gender differences were observed (p>0.05).

CONCLUSIONS: Clinicians face multiple presentations when evaluating SRC, and gender may drive some of this variability. Future studies should evaluate how initial presentation impacts treatment and outcomes.
