Much to my surprise, two leading health care journals have articles on ehealth.
The first is JAMA (vol 303, no 5, pp 391-470; February 3, 2010), which rarely publishes on the topic of ehealth.
The second is a special theme issue on global ehealth (Feb 2010, vol 29, no 2). The Health Affairs blog has a good description of the articles.
Looks like there’s an increasing interest by those in the research communities on the issues of ehealth. I haven’t had a chance to read all of the articles just yet, but it some of the titles look interesting.
