New data shows the types of drugs used to treat injured workers in California, and the distribution of payments for those medications, has shifted over the past decade, with opioids becoming far less prevalent and anti-inflammatory drugs accounting for an increasing share of the prescriptions and the total drug spend within the workers’ comp system.

Updated figures from the California Workers’ Compensation Institute ranks the top 10 therapeutic drug categories in the state’s workers’ comp system based on the volume of prescriptions and total reimbursements.

California workers’ compensation written premium for the first quarter of 2021 was 13% below that for the first quarter of 2020, according to a quarterly experience report issued on Wednesday by the Workers’ Compensation Insurance Rating Bureau of California.

The WCIRB report is an update on California statewide insurer experience valued as of March 31.

A new study shows that nonsteroidal anti-inflammatories (NSAIDs) now account for more than one-third of all drugs dispensed to injured workers in California, triple the proportion for opioids.

A study from the California Workers’ Compensation Institute released on Wednesday also shows that although most NSAIDs that are used are inexpensive, and utilization has been flat since the state’s evidence-based prescription drug formulary took effect in 2018, NSAIDs’ share of the total drug spend has soared from 14.2% to 23.5%.

The surge was largely driven by increased payments for two low-volume, high-priced drugs that are exempt from prospective utilization review and that lack price controls, according to the CWCI study.

Jose Zepeda, 45, of Fresno, Calif., self-surrendered this week on multiple felony counts of insurance fraud and attempted perjury after filing a workers’ compensation insurance claim and allegedly misleading the insurance carrier regarding his employment status in order to collect disability benefits he was not entitled to receive.

According to an investigation by the California Department of Insurance, Zepeda was injured in August 2017 while employed by a local construction company. Zepeda began collecting disability benefits because his employer could not accommodate his work restrictions. The insurance company handling Zepeda’s workers’ comp claim reportedly instructed him to notify them if he found new employment because that would affect the benefits he was receiving.

A new study from the California Workers’ Compensation Institute shows the steep drop in the number of inpatient hospitalizations involving injured workers in the state over the past decade was largely due to the ongoing decline in spinal fusions and a more recent decline in lower extremity joint surgeries.

The CWCI study reviews discharge data compiled by the state Office of Statewide Health Planning and Development on 35.9 million inpatient hospital stays from 2010 through 2019 paid by workers’ compensation, Medicare, Medi-Cal and private insurance, to identify workers’ comp inpatient trends and to compare the volume and types of California inpatient hospitalizations covered by workers’ comp to those covered by the three other systems.
