The core objective of our Stakeholder Engagement Work Group is to develop respectful and productive partnerships that will maximize our ability to generate trustworthy, internally valid findings directly relevant to veterans and military service members with pain, front-line primary care clinicians and health care teams, and health system leaders. The Work Group will provide the forum within which these stakeholders can bring their different perspectives and expertise to develop and enact a comprehensive, evidence-based, and stakeholder-informed approach to address previously identified organizational, clinician, and patient-level barriers to access, engagement and participation in pragmatic clinical trials of non-pharmacological approaches for the management of chronic pain and to optimize the VA and DoD as learning health care systems.
