Correlates of specialty substance use treatment among adults with opioid use disorders

Abstract

AimsTo identify factors associated with the receipt of specialty substance use treatment among adults with opioid use disorders (OUD). DesignCross-sectional study based on 2010–2014 National Surveys on Drug Use and Health (NSDUH). Setting and participantsAdults with a past-year OUD (n = 2488). The sample is representative of non-institutionalized US adults. MeasurementsPast-year OUD was determined using DSM-IV criteria. Past-year specialty substance use treatment was defined as receiving treatment for drug use at any of the following locations: rehabilitation facilities, hospitals (inpatient only), outpatient mental health centers, private doctors' offices, or methadone clinics. Multivariable logistic regression models were used to measure the independent association between potential correlates and specialty substance use treatment receipt. FindingsOf adults with an OUD, 8.3% received past-year specialty substance use treatment. In a fully adjusted logistic regression model, the following factors were associated with increased odds of receiving specialty substance use treatment: ≥ 35 years old (adjusted Odds Ratio (aOR) = 2.55, 95% Confidence Interval (CI) = 1.04–6.26); unemployment (aOR = 1.92, 95% CI = 1.02–3.61); not in the labor force (aOR = 2.16, 95% CI = 1.15–4.06); never been married (aOR = 2.14, 95% CI = 1.04–4.39); arrested in past 12 months (aOR = 4.43, 95% CI = 2.45–7.99); opioid dependence (aOR = 3.82, 95% CI = 2.06–7.10); alcohol use disorder (aOR = 2.44, 95% CI = 1.44–4.11); and another drug use disorder (aOR = 3.22, 95% CI = 1.95–5.32). Living in a non-metropolitan county (aOR = 0.29, 95% CI = 0.12–0.68) and fair/poor health (aOR = 0.38, 95% CI = 0.17–0.86) were associated with decreased odds of receiving specialty substance use treatment. ConclusionsThese findings suggest a need for the following efforts: strategies to increase individuals' recognition of their need for OUD treatment, expansion of insurance coverage for substance use treatment, expansion of earlier intervention services, adoption of a chronic care approach to substance use treatment, and an expansion of treatment capacity for rural communities.
