Rapid growth of costs for prescription drugs for injured workers in some states is a major issue for policymakers, but not in Washington State where costs were among the lowest compared to 17 other states, according to a new study by Workers Compensation Research Institute (WCRI).

WCRI’s study, Prescription Benchmarks for Washington, points out several state policies and programs that may have allowed Washington to keep prescription costs low — 40 percent lower than the median state, including:

• A formulary of approved drugs and therapeutic interchange,
• Lower then typical pharmacy fee schedule,
• Mandatory generic substitution, and
• Infrequent physician dispensing.

The study also provides a wealth of detailed price and utilization statistics that may be useful when debating such issues as: pharmacy fee schedules, physician prescribing patterns, medical cost drivers, and laws that mandate the use of generics.

The data used for interstate comparisons covers prescriptions for claims with injuries occurring in 2006 and includes all prescriptions through March 2008.  Reader should be cautioned that the results based on 24 months of experience understate the ultimate values of the metrics that depict quantities and costs.
