Care coordination represents a distinct contribution that requires education and dedicated nursing time, separate from the day to day tasks in a busy practice. To fully support these new functions, reimbursement models are needed that support such non visit-based work and provide incentives to coordinate and manage complex care, achieve improved clinical outcomes, and enhance efficiency. This type of analysis represents a useful approach for any health system seeking to optimize roles and critically evaluate its work. How primary care practices incorporate care coordination will vary based on practice size and setting, but each practice needs to address this fundamental need in order to fully embrace the PCMH model. This requires changes to workflow throughout the practice along with adjustments to role definitions among members of the care team.
