As payment reform pressures provider organizations to manage total cost of care for their patients across the continuum, leaders rely more than ever on primary care to provide upstream services that prevent more costly downstream utilization. To deliver effective, patient-centered care, organizations are transforming their primary care practices to deliver new-in-kind services that address the full range of needs contributing to patient health. This requires organizations to expand their care teams to help manage patients’ behavioral health, non-clinical, and complex care needs across an often-confusing system. Team-based primary care not only improves patient and population health, but also lowers health system costs overall.
