All other participants will then have the counselor explain about peer health care system navigation and introduce the participant to the PHN. The PHN will meet with the participant and schedule an initial discussion, unless the participant does not have any need for the navigation, in which case the PHN will plan to call after a few weeks to check for any emerging needs. The PHN will interact with the participant on a schedule that is independent of the study visit schedule and is determined by the participant's needs. The PHN's role will be to help the participant overcome his barriers to health care through a number of activities.
