Developed as part of SNMHI, the PCMH-A helps sites to understand their current level of “medical homeness” and identify opportunities for improvement. The PCMH-A can also be used to track progress toward practice transformation when it is completed at regular intervals. We strongly recommend that the PCMH-A be completed by a multidisciplinary group (e.g., physicians, nurses, medical assistants, residents, other operations and administrative staff) in order to capture the perspectives of individuals with different roles within the practice and to get the best sense possible of ‘the way things really work.’
