    The mixed message behind "Medication-Assisted Treatment" for substance use disorder.
    Am J Drug Alcohol Abuse 2017 Sep 18:1-4. Epub 2017 Sep 18.
    b UT Southwestern Medical Center , Department of Psychiatry , Dallas , TX , USA.
    The gap between treatment utilization and treatment need for substance use disorders (SUDs) remains a significant concern in our field. While the growing call to bridge this gap often takes the form of more treatment services and/or better integration of existing services, this perspective proposes that more effective labels for and transparent descriptions of existing services would also have a meaningful impact. Adopting the perspective of a consumer-based health-care model (wherein treatments and services are products and patients are consumers) allows us to consider how labels like Addiction-focused Medical Management, Medication-Assisted Treatment, Medication-Assisted Therapy, and others may actually be contributing to the underutilization problem rather than alleviating it.
