A recent study finds that many U.S. doctors regularly prescribe placebo treatments in the form of real drugs for medical care [1]. Most physicians surveyed view this practice as ethically permissible. The study also finds that many physicians are not fully transparent regarding the use of placebo treatments, and most commonly describe the placebo treatment to patients as a potentially beneficial medicine or treatment not typically used for their condition.
Following the Tweets of Health
November 1, 2008 | by
Twitter is a micro-blogging service that allows users to send and receive updates or “tweets”, which are short text-based posts. In contrast to a conventional blog, which combines text, images and links to other websites, a micro-blog post is typically restricted to 140 characters. Twitter users can “follow” others by visiting their profile page and clicking the “follow” button. Following someone simply means you will receive their Twitter updates. Interestingly, Twitter is also frequently being used as an instant messaging service, with lengthy real-time exchanges between users.
You might think that very little can be said when you’re restricted to 140 words, but just the opposite is true. You have to be succinct and get straight to the point. This has been a criticism of Twitter since it was launched in October 2006. Call it what you want. Soundbites … media snacking … everyone is busy today and consuming small bits of information is how we’re keep up with the world’s never-ending data stream.
Although there’s been a great deal of speculation in the blogosphere about the death of Twitter, it remains the most widely used micro-blogging service. I’ve mentioned previously that Twitter is a useful communication tool. The social media service allows you to connect with other people who share your interests. I’ve found a great many people interested in health and medicine on Twitter, and have been actively using it since early this year.
Mark Hawker, a health care informatician in the U.K., recently published a list of the Top 30 Health Tweeple or Twitter users. I’m honored to be one of the 30 Twitter users on the list. The top 30 health tweeple include physicians, nurses, medical librarians, medicine and health 2.0 educators and advocates, and healthcare entrepreneurs from around the world. Mark compiled the list of health tweeple you should follow “based on the quality of their contributions and their overall influence in the field.”
However, it was soon realized that many health tweeple were missing from the list. Thus, Mark’s follow-up post, The Forgotten Health Tweeple rounds the list up to 50. Although many of the top 50 health tweeple I already follow, Mark’s list introduced me to others I had not yet discovered.
Even though it’s subjective, I think Mark’s top 50 list accurately identifies people that are actively “tweeting” and discussing health, health 2.0 and medicine 2.0 online. This niche social network within a social network — the health community on Twitter — posts useful and informative content and frequently engages one another, exchanging information and resources. If you use Twitter and you’re interested in health, I highly recommend you follow the top 50 health tweeple.
Interestingly, consumers are also looking for companies on social media websites. Indeed, a recent study found that 93% of social media users believe a company should have a presence in social media [1]. This means that brands are being recognized and sought after in a social media environment. I mention this because I maintain two separate Twitter accounts, one for Highlight HEALTH, which provides a way for Twitter users to stay up-to-date with new articles and resources posted on the Highlight HEALTH websites, and a second for personal use (my personal account made the top 30 list). Feel free to follow both.
A word of caution: in my experience, it’s difficult to keep up with the flow of information when you follow too many people. I try very hard to only follow people that are engaging and share my interests. Even when you’re media snacking, you can eat too much!
Here’s a tip: easily keep up with tweets directed at you by locating the RSS link at the bottom of the @Replies page and subscribing to it in your feed reader. You can also convert the feed to email using a service such as Feed My Inbox and you’ll always know when someone sends you a tweet, even if you’re not currently using Twitter.

iMedix: Reliable Health Search and Patient-to-patient Social Network
October 28, 2008 | by
The Internet is used by 75% of American adults to search for health or medical information online; 1 in 10 are searching for health information right now as you read this [1]. Indeed, the amount of information available on the Internet related to health and medicine is staggering. While much of it is credible, an equal or greater amount of misinformation also exists.
Reliable sources of health information are extremely important to online health seekers. Enter iMedix, a health 2.0 service that combines a healthcare search engine and social networking. iMedix provides health consumers a way to find medical information that has been filtered for reliability and rated by patients with similar interests.
iMedix features
- Search any medical condition, symptom, treatment or drug on top online health sources
- Auto-complete and spell check search queries
- Community ranked health articles
- Health site reliability shown for search results
- Ask questions about any health topic
- Connect with people who share your health interests
The iMedix website makes it easy to transition between a reliable health web search, questions and answers asked in iMedix health communities and iMedix members — all with a single click.
Reliable Health Search
Why use iMedix to search for health information instead of Google? Simple … reliability of search results. iMedix is a community-powered healthcare search engine, which combines a vertical health search engine with a patient-to-patient social network. iMedix uses proprietary algorithms to evaluate healthcare websites and rate top sources. Dozens of thousands of websites that are approved by top medical accreditation organizations such as HON (Health On the Net Foundation) or URAC (Utilization Review Accreditation Commission) are cataloged by iMedix. Individual site accreditation is indicated in the search results along with a clear indication of the source of each article. The iMedix community then provides feedback by rating those sources, further improving the ratings. Thus, users benefit from the collective medical knowledge and experience of the iMedix community.
To the right of the web search results, several members of the iMedix health community associated with the search term are shown. Community members can also be searched by selecting the “Members” link at the top of the search results. The right sidebar also displays questions related to the search term, making it easy for users to transition from a web search to searching questions and answers posted by the iMedix community. Questions and answers can also be searched by selecting the “Q&A” link at the top of the search results. These three sections — web results, questions and answers, and iMedix members — are transposed with the user’s selection. If the user chooses web results, community members and related questions are shown in the sidebar. If the user chooses community members, related questions and web results are shown in the sidebar. iMedix thus allows a user to take a search term and, with one click, query three different data spaces.
The iMedix search engine supports the “AND” operator, allowing for complex searches with multiple parameters. Although you can use the iMedix search engine without signing up, you won’t be able to communicate with iMedix members nor ask or answer questions from the various health communities.
iMedix Health Communities
Although iMedix began as a blogging platform for patients, it has evolved into a patient-to-patient social network. iMedix health communities enable people to share and discuss their health issues with others. Currently, there are ~2000 communities, which iMedix plans to consolidate in the future. Popular communities are shown on the iMedix homepage. Users can easily sort health communities by disease, symptom or drug and browse them alphabetically.
iMedix users can “tag” themselves by indicating health interests in their profile. Many tags are used by iMedix to assign users to health communities, connecting them to other members with similar interests. Additionally, users can browse member profiles to find other users that share a health interest.
Asking a question is as simple as typing it in the “Ask Our Community” box on the right side of the page. The iMedix system extracts keywords and tags, and immediately distributes your question to relevant members. Questions and answers are moderated by community leaders as well as by the community itself. iMedix notifies you as soon as you receive answers to your question. Each answer that is given to a question can be rated by other users, giving it a “thumbs up” or “thumbs down”. Individual answers can also be reported for abuse.
I found user answers to be a mixed bag. Some answers were informative while others … not so much. As with any social network, you take the good with the bad. Like other online social communities, users can “friend” other members, adding members that they find interesting or well informed to their friends list.
What was notably absent was conversation. People with health problems want to talk and share with others that have similar issues. If you’re familiar with Internet forums or messages boards, you’ll be disappointed in the lack of such an application on the iMedix website. However, iMedix users can chat in real time or send offline messages to one another through a private messaging system. There may be an abundance of conversation between patients, but none of it is publicly accessible.
Where iMedix Shines
Immediately after iMedix launched, VentureBeat wrote a disparaging review of the healthcare-community site. Several comments seem overly critical; disapproving of the uncluttered homepage (wasn’t Google praised for its clean, sparse interface?) and skeptical at the lack of a business model. Indeed, when iMedix launched in December 2007, a press release described a direct-to-consumer advertising channel whereby iMedix would connect pharmaceuticals, insurance companies and medical organizations with highly targeted consumers, i.e. iMedix users [2]. The iMedix Privacy Policy clearly states that they “will occasionally send you information on products, services, special deals and promotions”. Note that iMedix provides the ability to ‘opt-out’ of having personally identifiable information used for certain purposes. Other comments seemed to state the obvious: “In effect, iMedix users have only two sources of information — the intermittently useful search function and individual conversations with other users.” While VentureBeat thought it gave the site a “conspicuously information-deprived feel”, I think it highlights the utility of iMedix: filtering out all the noise and misinformation in online health information and presenting a clean, uncluttered and well-organized health search results page.
Conclusion
I really like iMedix and think it’s a great service that will complement the emerging use of of PHRs and genetic testing. As Susannah Fox described in the The Plausible Promise of Participatory Medicine:
For those internet users who are supplementing their doctor’s advice with health information found online, search is the first stop for most e-patients. Search is the de facto second opinion in the United States and search results often include user-generated content such as blogs, discussion groups, and Wikipedia.
Social media is not just stumbled upon by searchers; it is a starting point for many people. This trend is hard to measure since a lot of user-generated content has become “wallpaper” technology for many people — they absorb it without noticing it. But community is powerful and always has been. Technology makes this basic instinct easier to fulfill.
I’ve written previously about the Trust and Credibility of Healthcare Blogs. Indeed, I think about the credibility and reliability of internet-based health information all the time. It’s the principle reason why I include links and list references in all my articles. Although presentation trumps content online today, I think health seekers are becoming more savvy and looking beyond website design for impartial and verifiable sources of information. iMedix makes finding those sources of information easy.
iMedix has been in beta for 10 months. In a May 2008 interview with CenterNetworks, iMedix co-founder and CEO Amir Leitersdorf said that the healthcare-community site had more than 500,000 users each month and, with the help of the iMedix community, had ranked and re-organized more than 20 million health articles [3]. In July 2008, the company announced its first major media partnership and will be powering the search capabilities of PARADE.com’s health section [4]. It will be interesting to see how iMedix develops over the next year as its user base continues to grow and mature.

2008 Presidential Candidates on the Issues of Biomedical Research and Healthcare
October 23, 2008 | by
A major determinant of America’s health and competitiveness in the world is progress in the life sciences. Over the past twenty years, the life sciences have had a tremendous impact on human health through the understanding of the molecular basis of disease and the development of new diagnostics, therapeutics and other medical products. Given the significance of biomedical research on healthcare, I felt it was important to highlight the 2008 presidential candidates’ positions. A number of online resources are discussed in this post and listed at the end of the article. With the election less than two weeks away, it is paramount that voters know where the presidential candidates’ stand on these essential issues.
Highlight HEALTH Goes Mobile
October 14, 2008 | by
As more and more people use cell phones, the Mobile Web — accessing the World Wide Web using a mobile device such as a cell phone, PDA or other portable device — is increasingly being used to access online information. According to AdMob, the world’s largest mobile advertising marketplace, in August 2008 mobile worldwide traffic grew 12.8% to 5.1 billion web page requests [1].
New smartphones like the iPhone are accelerating this use in the mobile web. Indeed, in August 2008 the iPhone saw the largest share increase of any smartphone [1]. With healthcare consumers and professionals increasingly relying on handheld devices to access the web, I’m pleased to announce that a mobile version of Highlight HEALTH is now available.
Standard mobile phones, Blackberries and 3G devices such as the iPhone and iTouch are fully supported. Optimized for the mobile web, http://www.highlighthealth.com enables readers to access all the articles on Highlight HEALTH while on the go.
At the bottom of every article, you can show and post comments. Additionally, there are links to “Email” the full HTML article link, “Bookmark on delicious” or “Share on Twitter”.
UPDATE:
Highlight HEALTH now automatically detects mobile devices like iPhones, iPads, Android & Blackberry and more, and serves an optimized theme instead of the regular desktop theme. Visitors can always switch back to the desktop theme if they choose.
According to a study last year, 75% of people who access the mobile web conduct searches [2]. As consumers use the Internet more than any other media source to research health information [3], I anticipate an increasing number of health-related searches to be done using the mobile web. I hope the mobile version of Highlight HEALTH will enhance its appeal to readers who have busy schedules and frequently don’t have time to read on a computer.
Mobile web users, please give the mobile version of Highlight HEALTH a try and let me know what you think.
