Peer Mentor activities The Peer Mentors will focus on assisting practice champions with addressing implementation and use hurdles specific to their practice. This assistance will be limited to an advisory role and will focus on reinforcing the need for practice champions to anticipate and plan for work process changes, encourage the development and use of effective team leadership techniques, and assist with addressing technical issues with regard to installation and use of the registry program. Peer Mentors will visit participating practices on a quarterly basis and have monthly phone conferences with practice champions throughout the 12-month intervention period.
