Concussion Management Policy Implementation in High Schools: Examining Policy Through a Disproportionality Lens.

Background and objectives: Evidence-based concussion practices have been codified into legislation, yet implementation has been narrowly evaluated. We examined implementation of concussion practices in Massachusetts high schools and adopted a disproportionality lens to assess the relationship between school sociodemographic and policy implementation and examine whether differences in policy implementation represent systematic disparities consistent with the disproportionality literature.

Methods: A cross-sectional survey was sent to Massachusetts high school nurses (N=304). Responses (n=201; 68.1% response rate) were tallied so that higher scores indicated greater policy implementation. School demographic data were collected using publicly available datasets and were linked to survey responses. Descriptive statistics, correlations, k-means clustering, and groupwise comparisons were conducted.

Results: Policy implementation is varied across schools and is associated with school sociodemographic variables. As percentages of marginalized identities in student population increased, implementation rates decreased. K-means cluster analysis revealed two discrete groups based on policy implementation scores, with significant differences in sociodemographic variables between groups. Schools with low implementation scores had a greater percentage of students who identified as African American/Black and nurses with less experience.

Conclusions: Findings highlight current disparities in the implementation of concussion management policies and support adoption of a disproportionality lens in this sphere.
