Service Delivery Models for the Management of Pediatric and Adolescent Concussion: A Systematic Review

Progesterone Levels in Adolescent Female Athletes May Contribute to Decreased Cognitive Performance During Acute Phase of Sports-Related Concussion

Although many outcome studies pertaining to sports-related concussion exist, female athletes with concussion remain an understudied group. We examined whether neurocognitive performance in adolescent females with sports-related concussion (SRC) is related to menstrual cycle-related hormone levels measured at one-week post-concussion, one-month post-concussion, or both. Thirty-eight female athletes, ages 14-18, were matched into two groups: SRC or healthy control. Self-reported symptom scores were higher among concussed females in the luteal phase, when progesterone levels are highest. Results suggest that progesterone levels may contribute to a heightened experience of symptoms during the acute phase of SRC, providing further evidence of a possible link between progesterone and symptom scores following concussion.

Predicting Time to Evaluation After Pediatric Concussion: Factors Affecting Specialty Concussion Care

Background

The timing of clinical evaluation after pediatric concussion represents an important and potentially modifiable clinical milestone for diagnosis, selection of appropriate treatment pathways, and recovery prognosis. Patient demographics, socioeconomic status, or medical history may affect the time to the initial evaluation and subsequently influence recovery outcomes.

Purpose/Hypothesis

The purpose of this investigation was to evaluate the association of patient characteristics with the time to specialty evaluation after a concussion. It was hypothesized that patients with a history of concussion, a preexisting relationship with our specialty concussion program, or a higher ZIP code-based income estimate would present for care more quickly after a concussion than patients without these characteristics.

Study Design

Cross-sectional study; Level of evidence, 3.

Methods

Included were patients with a concussion between 6 and 18 years old who were seen for care at a single sports medicine center between January 1 and December 31, 2019. Patient demographic, socioeconomic, injury, and clinical characteristics were collected through a retrospective review of the medical records. The primary outcome was the number of days between the date of the concussion and the patient's initial specialty evaluation.

Results

Overall, 220 patients (mean age, 14.4 ± 2.5 years; 46% female) were seen for care at a mean of 9.7 ± 5.6 days (range, 1-21 days) after concussion. A shorter time to specialty evaluation was associated with a history of concussion (β = -1.72 [95% CI, -3.24 to -0.20]; P = .03) and a prior clinical relationship with the treating clinical department (β = -1.85 [95% CI, -3.52 to -0.19]; P = .03). Referral by a primary care provider was associated with a longer time to evaluation (β = 3.86 [95% CI, 2.39-5.33]; P < .0001).

Conclusion

A history of concussion and having a preexisting clinical relationship with the deparment were associated with a shorter time to evaluation after concussion. Referral from a primary care physician was associated with a longer time to evaluation. Issues may exist in the propensity to access care after an injury, resulting in delays for initiating early treatment.
