Use of Primary Care and Emergency Departments for Substance Use Treatment: The Rural and Urban Divide

Abstract

Background : Alcohol and illicit substance use remain significant public health issues in the United States. In this analysis, we assessed differences in the use of primary care and emergency departments (EDs) for treatment of substance use among rural and urban sexual minorities (SMs). Methods : Data come from the National Survey on Drug Use and Health (NSDUH, 2015-2019). Survey-weighted multivariable linear and logistic regression analyses were used to assess the relationship between sexual identity and the use of primary care settings or EDs for treatment of substance use, stratified by urbanicity of residence. Results : Among the entire sample, 7.9% reported residing in rural environments with slightly more SMs living in urban (7.3%) relative to rural (5.4%) locales. Both rural (β=-0.20; 95% CI: −0.29, −0.10) and urban SMs (β=-0.13; 95% CI: −0.16, −0.11) self-reported worse overall health. Urban SMs, but not rural SMs, had significantly higher odds of reporting use of primary care treatment for substance use (aOR 2.80; 95% CI: 2.13, 3.68). ED treatment for substance use was greater among both rural (aOR = 2.99; 95% CI: 1.01, 8.87) and urban SMs (aOR = 3.02; 95% CI: 2.12, 4.30) as was overall number of ED visits among both rural (β = 0.48; 95% CI: 0.24, 0.72) and urban SMs (β = 0.23; 95% CI: 0.19, 0.28) . Conclusion : These findings suggest increased reliance on EDs for treatment of alcohol or substance use among rural SMs. Future research should examine whether increasing culturally competent primary care services for SMs in rural areas may be a key intervention point for reducing health disparities.
