Patterns of referral in high school concussion management programs: A pilot study of consultants from different disciplines

Methodological considerations of assessing meaningful/reliable change in computerized neurocognitive testing following sport-related concussion

OBJECTIVE

Traditional reliable change index (RCI) methods may be psychometrically limited due to their inability to account for particularly high or low baseline performance and regression to the mean following serial testing. The current study sought to examine differences between RCI and standardized regression-based (RBz) methods in a cohort of adolescent athletes engaged in sport-related concussion recovery.

METHODS

Consultation records and results of computerized testing data via the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery were retrospectively reviewed among 240 adolescent athletes involved in return-to-play protocols following a sport-related concussion.

RESULTS

High concordance rates were found between RCI and RBz metrics across ImPACT composites, consistent with previous literature. However, especially for those with lower baseline performance, RBz scores tended to suggest cognitive performance not meeting or exceeding baseline scores despite RCI metrics being appropriate across speed-based ImPACT composites. In contrast, results revealed high rates of RCI scores suggesting continued cognitive difficulties despite RBz metrics being within normal limits, especially for adolescents with higher baseline performance.

CONCLUSIONS

Results suggest value in interpreting RBz values in addition to RCI values as these allow for clinical interpretation more sensitive to statistical confounds, including baseline performance and regression to the mean.

Critical Elements of Return to Learn for Students With Concussion: A Scoping Review

OBJECTIVE

To identify critical elements of return to learn (RTL) for students with concussion and examine the state of the peer-reviewed published literature through a scoping review.

METHODS

Three electronic databases were systematically searched, and reference lists screened for articles addressing components of RTL protocols and accommodations for students with concussion. In total, 100 articles met inclusion criteria, including 56 empirical studies and 44 expert articles.

RESULTS

Four key components to RTL protocols were identified: RTL teams, management approaches, outcome measurement, and accommodations. Both bodies of literature agree on the importance of RTL teams, but evidence for specific monitoring tools and management approaches is less robust. Accommodations have been better addressed by experts than empirical evaluation. Empirical studies are largely cross-sectional, and many are survey based. Just 24 include student perspectives. Publication of expert literature has declined in frequency, as empirical studies have become more common.

CONCLUSION

This scoping review describes the current landscape of RTL and provides guidance toward expanding the empirical literature to systematically determine best practices to serve students with concussion.

Return on Investment and Value Research in Neuropsychology: A Call to Arms†

There is substantial empirical evidence to support the clinical value of neuropsychological evaluation and the incremental value of neuropsychological assessment, suggesting such evaluation is beneficial in the prediction and management of clinical outcomes. However, in the cost-conscious and evolving era of healthcare reform, neuropsychologists must also establish the economic value, or return on investment, of their services. There is already a modest body of literature that demonstrates the economic benefits of neuropsychological evaluation, which is reviewed in the current paper. Neuropsychologists will need to be able to communicate, and develop evidence of, economic value of their services; thus, this paper also discusses common concepts, terms, and models used in healthcare valuation studies. Finally, neuropsychologists are urged to incorporate these financial concepts in their clinical practice and research.
