Rural-urban differences in out-of-network treatment initiation and engagement rates for substance use disorders.

OBJECTIVE

To examine rural-urban disparities in substance use disorder treatment access and continuation.

DATA SOURCES AND STUDY

SETTING

We analyzed a 2016-2018 U.S. national secondary dataset of commercial insurance claims.

STUDY

DESIGN

This cross-sectional study examined individuals with a new episode of opioid, alcohol, or other drug use disorders. Treatment initiation and engagement rates, and rates of using out-of-network providers for these services, were compared between rural and urban patients.

DATA COLLECTION: We included individuals 18-64 years old with continuous employer-sponsored insurance.

PRINCIPAL FINDINGS: Patients in rural settings experienced lower treatment initiation rates for alcohol (36.6% vs. 38.0%, p < 0.001), opioid (41.2% vs. 44.2%, p < 0.001), and other drug (37.7% vs. 40.1%, p < 0.001) use disorders, relative to those in urban areas. Similarly, rural patients had lower treatment engagement rates for alcohol (15.1% vs. 17.3%, p < 0.001), opioid (21.0% vs. 22.6%, p < 0.001), and other drug (15.5% vs. 17.5%, p < 0.001) use disorders. Rural patients had higher out-of-network rates for treatment initiation for other drug use disorders (20.4% vs. 17.2%, p < 0.001), and for treatment engagement for alcohol (27.6% vs. 25.2%, p = 0.006) and other drug (36.1% vs. 31.1%, p < 0.001) use disorders.

CONCLUSIONS

These findings indicate that individuals with substance use disorders in rural areas have lower rates of initial and ongoing treatment, and are more likely to seek care out-of-network.
