Introduction: • Despite the high prevalence of Complementary and Alternative Medicine (CAM) usage, several recent surveys suggest that the vast majority of patient visits to CAM practitioners are self-referred and that communication between conventional and CAM practitioners is limited. • There is a need for a better understandingof factors influencing referral patterns across these two groups of practitioners. • Network analysis provides a useful tool to quantify relationships between members of an interrelated social network. • The goal of this follow up study was to quantify the cross-class referral patterns between conventional and CAM classes of practitioners in Chittenden County Vermont as well as gather additional information on the basis of referrals for future studies. • This study was a preliminary examination of possible reasons for the referral patterns.https://scholarworks.uvm.edu/comphp_gallery/1039/thumbnail.jp
