Clinical Trials

Integrating Behavioral Health in Primary Care (IBH-PC)

This study implements and evaluates specific practice improvement strategies to generate a greater degree of behavioral health-primary care integration than usual, co-located behavioral health and primary care. Funded by the Patient Centered Outcomes Research Institute.

Model Agnostic Framework for Integrated Behavioral Health

Leveraging work with the IBH-PC study, this study culminated in the development of a model agnostic framework for fully integrated mental and medical care within primary care and other settings. This set of processes and structures stretch across models of integrated care and was adopted as the community standard by the Institute for Clinical Systems Improvement (ICSI) in Minnesota, which leads the MN Health Collaborative, and includes a statewide effort to improve IBH in primary care through their Mental Health Collaborative.

In the news:
Kari Stephens, PhD, Associate Professor and Director of Clinical Research Informatics in the department of Family Medicine at the University of Washington, recently spoke with Healio Primary Care about the Integrated Behavioral Health (IBH) Cross-Model Framework, published in Translational Behavioral Medicine, that she and fellow researchers developed to support behavioral health in primary care clinics. Recognizing the need for a common definition across the various models of IBH, the research team created this framework as a cross-model definition of IBH in primary care that includes evidence-based processes and structures. The framework has been adopted by Minnesota’s MN Health Collaborative and published as a key community standard in their “Call to Action”. In partnership with the Collaborative, the research team evaluated the real-world usability of the framework in a state-wide effort detailed in published journal article.

The WPRN is a collaborative group of over 80 primary care practices in the five-state WWAMI region (Washington, Wyoming, Alaska, Montana, and Idaho) committed to research and practice improvement. Its mission is to improve the health and well-being of patients in their communities through the conduct of collaborative research that informs and enhances primary care clinical practice. The WPRN’s diversity of geography and practice type allows it to reach many rural and underserved populations. WPRN Data QUEST practices are located in rural and urban Idaho and Washington State.

WPRN Data QUEST clinic characteristics:
• Community Health Centers and Rural Health Centers
• Clinics range from less than 6,000 to 55,000 patient visits/year
• Clinics are in towns and cities of varying sizes, with populations of smaller than 1000 to over 200,000.

The DARTNet Institute is a rapidly growing collaboration of practice-based research networks that are building a national collection of data from electronic health records, claims, and patient-reported outcomes. The networks blend quality improvement, effectiveness, and translational research with a data-driven learning system. The learning system includes advanced performance measures and assistance with the development and deployment of clinical decision support systems. The WPRN is a close collaborator with the DARTNet Institute and can help facilitate research projects across the sister networks to allow for much broader national representation and diversity in populations needed to drive innovative health discovery.



The Institute of Translational Health Sciences offers resources that increase the speed at which scientific discoveries can be translated into treatments and clinical practices that improve health outcomes for patients and communities. More than 6,000 researchers from nearly 200 different institutions across the five-state WWAMI region have collaborated with us to attract grant funding, build their research teams, develop research tools, move research projects forward, and engage with patients and the community.
