The patient-centered medical home (PCMH) is a model of care that emphasizes the coordination of patient treatment among health care providers. Practice transformation to this model, however, presents a number of challenges. One of these challenges is getting the buy-in of all personnel to commit to making organizational changes in the journey to becoming a nationally recognized medical home. This study investigated internal messages of buy-in as communicated by practices transitioning to this type of care. Grounding itself in stakeholder theory, this study analyzed interviews with staff, administration, and practitioners from 20 medical practices in a mid-Atlantic state. The analysis revealed three overarching themes: (a) communication among staff that is open, consistent; (b) implementation of reinforcement techniques; and (c) access to a change implementer who encourages successful evolution. Discussion of these themes provides recommendations for communication approaches to organizational buy-in for medical practices hoping to become a PCMH.
