Overview

Observational study reveals moderate temporal stability for a multidimensional occupational burden index across administrative workplace records, suggesting utility for preventive surveillance.

Key Points

  • To develop the Composite Occupational Recorded Burden Index (CORBI) and evaluate its temporal stability using administrative occupational injury and disease records.
  • Analyzed 314,140 occupational injury and disease records from a Spanish mutual insurance society (2022–2025), yielding 239,140 episodes across 208 occupation-by-recorded-sex cells with at least 100 episodes.
  • Constructed CORBI by integrating four equally weighted dimensions and assessed temporal stability by applying development-period parameters to 2025 data, alongside sensitivity analyses across thresholds.
  • Across 113 comparable occupation-sex cells, temporal stability between development and 2025 demonstrated a Spearman correlation of 0.677 and a mean absolute change of 4.26 points.
  • A total of 88.5% of cells remained in the same or an adjacent quartile, 14 of the top 20 cells remained in the top 20, and rankings differed notably from a trauma-centered comparator.
  • Sensitivity analyses across different thresholds demonstrated rank correlations of 0.994 to 0.998 with the primary solution.
