Even though medication is considered the most effective therapy for opioid addiction, many Americans who need it don't receive it, a new study finds.
"Evidence supporting the effectiveness of medication for opioid use disorder — such as methadone, buprenorphine or naltrexone — is unequivocal, but most people who needed [opioid addiction] treatment in the U.S. did not receive this gold standard treatment," said study lead author Pia Mauro. She is an assistant professor of epidemiology at Columbia University Mailman School of Public Health, in New York City.
For the study, Mauro's team analyzed 2019 national survey data on teens and adults who could benefit from medication for opioid addiction. All met criteria for a past-year opioid addiction, reported past-year medication for opioid addiction or received past-year specialty treatment for opioid use.
People who were institutionalized and homeless people who weren't in shelters weren't included in the study.
The analysis showed that only 28% of teens and adults with opioid addiction received medication, 15% received services without medication, and 57% received no treatment.
Youth aged 12 to 17 did not receive medication in the past year, and only 13% of adults 50 and older received medication. Among adults, the likelihood of receiving medication compared to no treatment was lower for those 50 and older than for those aged 18 to 25.
Race made a difference, too. Nearly one-third of white individuals received medication, compared with about 20% of Black and multiracial people, and 15% of Hispanics. On the other hand, similar percentages of each racial and ethnic group received non-medication services.
Rates of treatment with medication were lower among women, more likely among adults with at least some college education, and less likely in small cities than in large cities, the findings showed.
The study was published online March 23 in JAMA Network Open.
"Our nationally representative research revealed critical gaps in treatment engagement and use of medication for opioid use disorder. Increased efforts to address barriers to care are critically needed," Mauro said in a school news release.
Since 2020, Medicaid has been required to cover all three U.S. Food and Drug Administration-approved medications for opioid addiction.
Policies that expand Medicaid coverage for these medications could potentially increase access to effective treatment in the publicly insured population, said study co-author Hillary Samples, an assistant professor at Rutgers School of Public Health in New Jersey.
