While the Internet is capable of supporting non- mediated relationships between producers and users of information, most medical information that is disseminated though the Internet is mediated. A variety of information intermediariesi provide mediated medical information on the Internet that helps physicians (decision-makers) and patients (decision-receivers) in clinical decision-making (Detmer and Shortliffe, 1997; Ferguson, 1996; Goldstein and Flory, 1997). These intermediaries include web-based medical literature providers, Internet patient records providers, integrated medical information providers, electronic journals and web-based medical support/ discussion/ chat groups, who perform the task of information intermediation. Some of these are just Internet-automated versions of traditional forms of information intermediation (e.g. electronic journals) while others are new forms of information intermediation (e.g. web-based discussion groups).
