The study provides policymakers and other system stakeholders in Illinois with ongoing annual monitoring of changes in indemnity benefits, medical payments, and benefit delivery expenses per claim. It also compares the Illinois workers’ compensation system with 17 other study states on these key metrics.

This edition analyzes claims with injury dates between 2018 and 2023 (evaluated as of March 31, 2024). In some cases, we use a longer time frame to supply historical context for key metrics and to provide a broader context for monitoring changes in Illinois’s system performance. Where relevant, we include findings from other recent Workers Compensation Research Institute (WCRI) studies to provide a more comprehensive picture of the Illinois workers’ compensation system.

The results reflect claims experience through March 2024, including non-COVID-19 claims. As a result, the study provides a detailed look at how the pandemic-related disruptions affected non-COVID-19 workers’ compensation claims in the early pandemic years (2019–2021) and more recently (2021–2023).
