HonorHealth, evolvedMD report 100% adoption of collaborative care across 32 primary care sites

HonorHealth and evolvedMD released a five-year case study showing systemwide rollout of the Collaborative Care Model across 32 Phoenix-area primary care locations, with up to 15% lower total cost of care and strong depression and anxiety outcomes. The case study is meant as a blueprint for health systems trying to scale behavioral health integration without adding major staffing burdens.

Why it matters: - The case study shows one path for health systems to expand behavioral health access inside primary care at scale. - HonorHealth said the model helped reduce delays in treatment by giving patients behavioral health support in a familiar care setting. - The reported cost savings and clinical outcomes suggest integrated behavioral health can improve care while easing pressure on primary care teams.

What happened: - evolvedMD and HonorHealth released a five-year case study on July 27, 2026. - The study tracks HonorHealth Medical Group’s rollout of the Collaborative Care Model from a four-site pilot in 2020 to full adoption across all 32 primary care locations in 2025. - HonorHealth is one of Arizona’s largest healthcare systems. - evolvedMD is a behavioral health integration provider.

The details: - The case study reports 100% Collaborative Care Model adoption across all 32 HonorHealth Medical Group primary care locations. - The study reports a 64.29% PHQ-9 remission/response rate among 1,093 patients with severe depression. - The study reports a 63.27% GAD-7 remission/response rate among 2,807 patients with severe anxiety. - The study reports up to 15% risk-adjusted total cost of care savings. - Each evolvedMD Behavioral Health Manager supported 90 to 100 active patients. - Primary care providers averaged 10 to 11 active behavioral health patients per clinician. - The workload was designed to support primary care teams rather than strain them. - HonorHealth said the partnership removed the need to recruit, train and manage a specialized behavioral health workforce. - The release says that staffing burden is a common barrier that prevents many health systems from expanding CoCM beyond pilot programs. - Jared Berkowitz, HonorHealth’s chief medical officer for primary care, said the relationship with evolvedMD helped deliver timely behavioral health care and improve outcomes.

Between the lines: - The release positions the HonorHealth rollout as evidence that collaborative care can move beyond a pilot and become a systemwide operating model. - The five-year timeline matters because many behavioral health integration efforts stall before reaching broad adoption. - The combination of clinical results and cost savings is the strongest part of the case for health system leaders weighing investment in integrated care. - The release also frames measurement-based care and implementation support as the key ingredients for scale, not just clinical intent. - Erik Osland, CEO of evolvedMD, said the case study is a roadmap for systems that want to address the behavioral health access crisis.

What's next: - The full case study is available now. - evolvedMD is inviting health system leaders interested in implementing or scaling Collaborative Care to contact the company directly. - The release says the results reflect the parties’ experience under the Collaborative Care Model and are not an endorsement by HonorHealth of any vendor, product or service.

The bottom line: - HonorHealth’s rollout suggests collaborative care can scale across a large primary care network while showing measurable clinical and financial gains.
