Two predictive models were developed that mimic acute concussion assessment using multivariate logistic regression based on a battery of postural control, neurocognitive status, and symptom assessments. The first predictive model gives a concussion status prediction based on change scores computed using individualized baseline testing information, whereas the second model uses normative reference values. The investigators defined and computed a novel metric called the Diagnostic Utility of Baseline Testing by comparing the concussion status predicted by each of these predictive models. The Diagnostic Utility of Baseline distribution was analyzed across athlete demographic characteristics and medical history.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The study included 1081 collegiate athletes (43.9% female) with 1279 acute concussion assessments (24- to 48-hour postinjury assessments) and 1551 reference assessments (baseline and 6-month assessments). Both the baseline and normative models exhibited notably high area under the curve values of .89 and .90, respectively. Most athletes (86.7%) did not gain additional diagnostic benefits from baseline testing versus normative values.

Thus, normative data can be used for most collegiate student-athletes in the absence of baseline testing. Moreover, these results can inform decisions on the allocation of baseline tests in resource-limited athletic settings, emphasizing the need for targeted concussion assessment strategies based on individual characteristics.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/03635465241296868","type":"journal-article","created":{"date-parts":[[2025,1,1]],"date-time":"2025-01-01T04:02:11Z","timestamp":1735704131000},"page":"181-191","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["Quantifying the Diagnostic Utility of Baseline Testing in Concussion Management: An Analysis of Collegiate Athletes From the NCAA-DoD CARE Consortium Dataset"],"prefix":"10.1177","volume":"53","author":[{"given":"Himadri S.","family":"Pandey","sequence":"first","affiliation":[{"name":"H.
