Improving the effectiveness of SUD treatment through a national registry.

Context: Recent research into the effectiveness of abstinence-based substance use disorder (SUD) treatment indicates that there has not been a substantial improvement since the Drug Abuse Treatment Outcome Study research in 1993. Research into medication-supported treatments for SUD are hindered by a dearth of real-world longitudinal outcome studies. Patient registries have dramatically improved survival rates in many diseases by providing researchers with longitudinal data on a broad spectrum of patients undergoing a variety of treatments.
