 A list of practicing family physicians will be obtained from the chiefs of Family Medicine at local hospitals in Toronto, Ottawa, Timmins, and Thunder Bay. We will develop a sampling frame for each site reflecting the proportion of solo and group practitioners in the community. A statistician independent of the study will generate a random number sequence to allocate practitioners to the control or intervention groups. There is a potential danger of contamination if two family physicians are recruited from the same group practice and randomized to different study arms, therefore only one physician per practice will be invited to participate in the study. Once one family physician has been recruited from a practice, all other physicians from the same practice will be deleted from the sampling frame.
