As states institute opioid policies to address the opioid epidemic, a new study has found considerable decreases in the prevalence of longer-term dispensing of opioids to injured workers in a number of states studied.
The frequency of claims that received opioids on a longer-term basis decreased more than four percentage points in Kentucky and New York, according to the study, Longer-Term Dispensing of Opioids, 4th Edition, by the Workers Compensation Research Institute (WCRI). The study examined trends in 26 state workers’ compensation systems.
The study found the frequency of claims decreased two to three percentage points in several other states (Kansas, Massachusetts, Michigan, Minnesota and Tennessee). Noticeable decreases in the longer-term dispensing of opioids were also seen in several states, including California, Florida and Texas, with reductions of one to two percentage points.
Among claims with injuries in 2013 observed over a two-year period ending March 2015, longer-term dispensing of opioids was most prevalent in Louisiana. Compared with most study states, the number was also higher in California, Georgia, North Carolina, Pennsylvania, South Carolina and Texas. By contrast, about 1 in 25 injured workers with opioid prescriptions received them on a longer-term basis in Indiana, Kansas, Missouri, Nevada, New Jersey and Wisconsin.
The study also found fewer than expected injured workers who received opioids on a longer-term basis had certain services (drug testing, psychological evaluation and treatment, etc.) recommended by treatment guidelines for chronic opioid management.
“Research finds high doses and prolonged use of opioids may lead to addiction, increased disability or work loss, and even death,” said Ramona Tanabe, WCRI’s executive vice president and counsel.
This study used data comprising more than 400,000 nonsurgical workers’ compensation claims with more than seven days of lost time; more than two million prescriptions are associated with these claims from 26 states. These claims had injuries in 2010 and 2013 and received on average up to 24 months of medical treatment. The sample of claims in the study represents 36-69 percent of workers’ compensation claims in each state.
The 26 states in the study are Arkansas, California, Connecticut, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nevada, New Jersey, New York, North Carolina, Pennsylvania, South Carolina, Tennessee, Texas, Virginia and Wisconsin.
