The CompScope™ series of reports provides ongoing annual monitoring of how indemnity benefits, medical payments, and benefit delivery expenses per claim change over time, as well as how the Illinois workers’ compensation system compares with 16 other study states (Arkansas, California, Florida, Georgia, Indiana, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, New Jersey, North Carolina, Pennsylvania, Texas, Virginia, and Wisconsin) on these key metrics. The report covers injury dates from 2008 to 2013 and payments through the end of March 2014. For some important key metrics used in this report, we use data for injuries before 2008 to provide a broader context for evaluating effects of changes related to the 2011 reforms in Illinois. Current and future editions of this study will enable stakeholders to observe and evaluate key metrics of system performance change and compare this with the expectations and goals of the reforms to see if mid-course corrections are needed.
