I wonder if you have taken a look at the new BMJ, which has a theme of cmc in healthcare. http://bmj.bmjjournals.com/cgi/content/full/328/7449/1143 and particularly, the following: Health related virtual communities and electronic support groups: systematic review of the effects of online peer to peer interactions. Gunther Eysenbach, John Powell, Marina Englesakis, Carlos Rizo, and Anita Stern. BMJ 2004 328: 1166-0. I don't know if any members of this list are working in the area of healthcare-related cmc, particularly peer-to-peer, but I'd certainly be interested in knowing if that's the case. My work to date has been with a large forum (200,000 members) whose intent is smoking cessation. I'd be very interested to see reactions to this article, which is available full-text through the BMJ website.
