abstract="OBJECTIVE: To examine predictors of prolonged symptom duration from mild traumatic brain injury (mTBI) in a pediatric sports medicine specialty clinic cohort as these predictors may be distinct in this population. <br><br>DESIGN: Retrospective chart review. SETTING: Outpatient specialty clinic. PATIENTS: Charts of 549 patients (age range: 10-18 years) with concussions were reviewed in an outpatient clinic that predominantly managed sports-related injuries (77.3%). Patients (n = 431) included in the final analysis met the criteria for mTBI and were symptomatic at their first visit. ASSESSMENT OF RISK FACTORS: Patient history, injury, and recovery variables were evaluated. MAIN OUTCOME MEASURES: Predictors of prolonged time to reach self-reported symptom recovery were evaluated using Cox proportional hazards. <br><br>RESULTS: Median time to symptom recovery of the 431 patients who presented to clinic with symptoms was 40 days (full clinic sample median = 34 days). Analyses identified 3 unique predictors of symptom recovery: loss of consciousness (LOC) [hazard ratio (HR) = 0.56, P < 0.0001], female sex (HR = 0.57, P < 0.0001), and concussion symptom score at first clinic visit (HR = 0.76, P < 0.0001). <br><br>CONCLUSIONS: Prolonged duration of mTBI symptoms in patients who present to a pediatric sports-based concussion clinic is related to initial symptom severity, female sex, and LOC.<p /> <p>Language: en</p>",
