Background
Despite increasing opioid overdose mortality, problems persist in the
availability and quality of treatment for opioid use disorder (OUD). Three
FDA-approved medications (methadone, buprenorphine, and naltrexone) have
high quality evidence supporting their use, but most individuals with OUD do
not receive them and many experience relapse following care episodes.
Developing and organizing quality measures under a unified framework such as
a Cascade of Care could improve system level practice and treatment
outcomes. In this context, a review was performed of existing quality
measures relevant to the treatment of OUD and the literature assessing the
utility of these measures in community practice.
Methods
Systematic searches of two national quality measure clearinghouses
(National Quality Forum and Agency for Healthcare Research and Quality) were
performed for measures that can be applied to the treatment of OUD. Measures
were categorized as structural, process, or outcome measures. Second stage
searches were then performed within Ovid/Medline focused on published
studies investigating the feasibility, reliability, and validity of
identified measures, predictors of their satisfaction, and related clinical
outcomes.
Results
Seven quality measures were identified that are applicable to the
treatment of OUD. All seven were process measures that assess patterns of
service delivery. One recently approved measure addresses retention in
medication-assisted treatment for patients with OUD. Twenty-nine published
studies were identified that evaluate the quality measures, primarily
focused on initiation and engagement in care for addiction treatment
generally. Most measures and related studies do not specifically incorporate
the evidence base for the treatment of OUD or assess patient level outcomes
such as overdose.
Conclusion
Despite considerable progress, gaps exist in quality measures for OUD
treatment. Development of a unified quality measurement framework such as an
OUD Treatment Cascade will require further elaboration and refinement of
existing measures across populations and settings. Such a framework could
form the basis for applying strategies at clinical, organizational, and
policy levels to expand access to quality care and reduce opioid-related
mortality.
