Efficacy of Brief Intervention for Unhealthy Drug Use in Outpatient Medical Care: a Systematic Review and Meta-analysis

Integration of substance use disorder treatment in traditional mental health facilities: Timeseries and cross-sectional evaluations

BACKGROUND

Despite efforts to increase substance use disorder (SUD) treatment provision in the United States (US), the extent to which traditional mental health (MH) facilities offer SUD treatment remains unclear. In the present study, we analyzed the trend in SUD treatment integration among traditional MH facilities in the US from 2014 to 2020 and identified facility-level factors associated with SUD treatment provision.

METHODS

Data were extracted from the National Mental Health Services Survey (N-MHSS). A timeseries logit trend analysis for the multi-year dataset (2014-2020) was conducted to assess a yearly change in odds of SUD treatment provision. With the 2020 survey data, analyses were conducted to identify the differences between facilities offering SUD treatment and facilities not offering such treatment. Finally, exploratory multivariable logistic regression was conducted to estimate odds of SUD treatment provision by facility variables.

RESULTS

US MH facility SUD treatment provision went from 51.7 % (2014) to 57.9 % (2020). A mean sample of 12,312 US MH facilities over seven years, demonstrated a significant but small yearly increase in SUD treatment provision (OR = 1.04, 95 % CI = 1.03, 1.04). Important facility characteristics related to SUD treatment provision for facilities without a core SUD focus were MH diagnostics offered (OR = 2.03), dual-diagnosis program offered (OR = 3.65), state drug/alcohol license maintained (OR = 6.66), and VA setting (OR = 7.94).

CONCLUSIONS

Despite incremental progress in integrating SUD treatment services into US MH facilities, the SUD treatment gap remains large. Training and service development incentives for identified characteristics could help further reduce the treatment gap.

Evaluating the substance use disorder treatment gap in the United States, 2016-2019: A population health observational study

BACKGROUND AND OBJECTIVES

Only 10% of Americans with substance use disorders (SUDs) receive treatment with insufficient treatment access and screening practices proposed and potential contributing factors.

METHODS

This retrospective cross-sectional study used National Survey on Drug Use and Health (NSDUH) data to assess individuals with SUDs receiving treatment between 2016 and 2019 (survey n = 12,111; weighted n = 12,394,214). Demographic, access, and screening characteristics were investigated as predictors of treatment receipt using time-series logistic regression analyses to test trends and assessed treatment receipt odds, controlling for demographic and treatment characteristics.

RESULTS

For those with past-year SUDs, 13.0% reported receiving past-year SUD treatment (survey n = 1605; weighted n = 1,612,154). The SUD treatment receipt rate remained statistically stable from 2016 to 2019, with a nonsignificant treatment receipt trend declining from 14% to 12%. Treatment changes were notable among Native Americans (+53.80%), Pacific Islanders (+94.10%), multiracial (-59.96%), ages 65+ (-70.18%), and ages 12-17 (-50.70%). In the regression model, race, sex, age, insurance status, and receiving mental health treatment were associated with SUD treatment receipt.

DISCUSSION AND CONCLUSIONS

The treatment gap remains substantial and stable. Annually, about 87% of Americans with SUDs are not receiving the treatment they need. Asian Americans were less likely and those attending general mental health services were more likely to receive treatment.

SCIENTIFIC SIGNIFICANCE

We present an updated SUD treatment gap evaluation, and identify access and screening characteristics associated with SUD treatment receipt. Policymakers, clinicians, and researchers must continue improving access and identification of those in need of care.
