Abstract

fetched live from OpenAlex

PURPOSE: The objective of the current study was to determine the degree to which individual prognostic factors obtained within the first 3-4 weeks of the initiation of a work-related back injury claim can predict claim cost and claim duration. METHODS: Prognostic factor data and outcome data regarding claim cost and duration were obtained from back injury claimants via an online questionnaire and the local workers' compensation board. Regression models were used to determine which of the factors were best able to predict claim cost, claim duration, and chronic work disability. RESULTS: Age, disability, and an accommodation and/or early return-to-work program being offered were included in the three final regression models and were therefore deemed to be best able to predict all three outcomes. Recovery expectations was also included in the final regression model for claim duration and is therefore able to assist in the prediction of this outcome. CONCLUSION: The regression models produced in the current study could be used to formulate equations to estimate claim cost and duration, thereby allowing insurers to identify "high-risk claims" early in the claim process and facilitate more targeted interventions in such cases. As well, whether an accommodation and/or early return-to-work program is offered is highlighted as a modifiable risk factor that could be used by insurers, employers, and workers to reduce claim cost and claim duration.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
