Impact of Increasing Numbers of Trauma Activation Criteria on Outcomes and Resource Utilization: A Multicenter Study.

The study is retrospective and cannot prove that adding criteria causes overtriage; it only shows an association. Data on the specific criteria used by each hospital came from a survey, which may be subject to recall bias or inconsistency. The analysis grouped similar criteria together, which introduces some subjectivity in how criteria were counted. The study used the Cribari matrix method to define overtriage and undertriage, which relies on the Injury Severity Score (ISS) and may not fully capture resource use or patient outcomes. The findings may not generalize to all trauma systems, particularly those outside the United States or with different operational structures.

No specific funding sources or conflicts of interest are explicitly detailed in the provided text segments.

Do not interpret the lack of association between criteria count and undertriage as evidence that current criteria are perfectly sensitive. The study shows that adding more criteria does not reduce undertriage, but it does not evaluate the performance of individual criteria or suggest that the standard eight criteria are optimal for every center.
