Transforming Behavioral Health Systems through Measurement-Based Care


The rapid uptake of Measurement-Based Care (MBC) across North America is undeniable, as more clinics, hospitals, large organizations, and health systems continue to prioritize its implementation to elevate the standard of care they deliver. National accrediting bodies like the Joint Commission are making a major push to drive MBC adoption, recognizing it as a foundational component of any high-quality and evidence-based behavioral health services.

On April 25th, we dove into the transformation of behavioral health with three health system leaders with deep MBC and value-based care (VBC) expertise. Hosted by Greenspace Co-Founder and President, Simon Weisz, our expert panel featured Melinda Lehman, Executive Director of Behavioral Health Care and Human Services at the Joint Commission, world-renowned applied psychologist and leading global expert on MBC, Dr. David Clark, and CareSource’s Senior Director of Complex Health Solutions, Behavioral Health, Dr. Sandra Berg.

With their combined expertise, our guests tackled a variety of MBC topics, including the value of, and evidence behind, a system-level approach to measurement and evaluation, insights to inform large-scale implementations, and the intersection between MBC and VBC.
