Services Research Branch (SRB)

What We Do:

The Services Research Branch (SRB) supports rigorous research to improve population health by maximizing the efficient delivery of high-quality, personalized addiction treatment and related services.  SRB seeks advance science to inform the design and implementation of stigma-free patient-centered systems of care so that people who experience addiction can recover and sustain their recovery over the long-term.

Research Interests:

SRB has developed a portfolio of research that includes a range of methods and approaches, including, but not limited to: implementation science, comparative effectiveness trials, integrated treatment approaches, quality improvement efforts, treatment adaptations, cost-effectiveness studies, insurance coverage and policy research, mHealth interventions, cross-system data integrations, modeling studies, and building learning systems of care.

Across this diverse set of methodological approaches, SRB seeks to advance science that supports providing high-quality personalized addiction treatment services to people to support their sustained recovery from addiction. SRB supports research at multiple levels (individual, clinician, organization, community, and systems) to achieve this goal.

Examples of specific topics of interest include:

• Developing and testing strategies aimed at optimizing the sustainability and scalability of evidence-based practices, including leveraging technology to enhance implementation
• Enhancing the use of data to build learning systems of care and drive improvements in care delivery and patient outcomes
• Identifying diverse strategies to improve treatment engagement and retention, with specific attention to reducing disparities for vulnerable and under-represented populations
• Developing and testing approaches to supporting long-term sustainable recovery
• Improving transitions across systems of care (e.g., from justice settings to community settings, from emergency care to specialty care)
• Studies to understand and address workforce dynamics (e.g., recruitment, retention, turnover) that influence the quality of service delivery
• Across all topics of interest, applicants are strongly encouraged to incorporate the following priorities (“SPECS”) into their study designs:
  • Sustainability
  • Patient/stakeholder engagement
  • Equity
  • Connecting research to practice
  • Scalability
