Study: California Workers Not Weaned Off Opioids Had Much Higher Drug Costs

Injured workers who were not weaned off of opioids had much higher drug costs and higher treatment transaction volumes, according to a report released on Friday by the Workers’ Compensation Insurance Rating Bureau.

The report, Study of Chronic Opioid Use and Weaning in California Workers’ Compensation, uses data from the WCIRB databases of medical transaction records and unit statistical reports to help understand the cost implications of chronic opioid use and the process of weaning injured workers off of opioids in California workers’ comp.

The study also shows that since 2012, claims with opioid prescriptions in the California workers’ comp system have dropped sharply, but opioid prescriptions still reflect a significant portion of all pharmaceutical costs.

The recent decline in opioid use is attributable to both fewer newer claims for which opioids were prescribed and a reduction in opioid use on claims in which there was “chronic” opioid use, according to the study.

Key findings of the report include:
