In September of 1994, John Lester, my colleague in the Department of Neurology at Massachusetts General Hospital, showed me an online bulletin board for neurology patients that he had created [1]. In reading through the online messages, I observed hundreds of patients with neurological diseases sharing their experiences and discussing their problems with one another.

These “patient stories” often included a number of empowering elements that set them apart from the advice patients typically receive from their clinicians: role modeling by an active, critical, well-informed “expert patient” ([1]; http://patientweb.net), comparative reviews and recommendations of clinicians and treatment facilities [2–5], and advice about how to handle the practical details of living with a chronic illness [6] (such as how to organize a home medical record, manage treatment side effects, find the best drug prices, and deal with less-than-perfect health professionals and health-care provider systems, and a wide variety of other topics relating to effective medical self-management). These extended patient narratives—no two alike—thus gave rise to an accumulated body of what my colleagues and I began to think of as an expert patient knowledge base. We concluded that these patient narratives could be invaluable resources for clinicians and researchers, interested in taking an in-depth look at the changing roles of patients and clinicians in the Internet age.

The constant outpouring of sympathy and support that we observed in interactions among community members surpassed anything a patient might conceivably expect to receive at a doctor's office. As Richard Rockefeller, President of the Health Commons Institute, has suggested, disease-specific online patient networks provide their members with an invaluable type of around-the-clock support that he has called the “chicken soup of the Internet” [7].

Working with several colleagues, I initiated an observational study to analyze the ways in which E-patients were using this new medium. Since I am an epilepsy specialist, we decided to focus on an epilepsy support group at the site Lester had created, BrainTalk Communities (http://www.braintalk.org) (Figure 1) [8]. The BrainTalk Communities currently host more than 300 free online groups for neurological conditions (such as Alzheimer disease, multiple sclerosis, Parkinson disease, chronic pain, epilepsy, and Huntington disease) for patients across the globe. More than 200,000 individuals visit the BrainTalk Communities' Web site on a regular basis. This site is now owned and operated by an independent nonprofit group, BrainTalk Communities, and is no longer formally associated with Massachusetts General Hospital.

Some other types of information, especially practical tips for living with epilepsy and the social aspects of the disease, went far beyond what I had been providing for my own patients. I am a board-certified epilepsy specialist at one of the most highly respected medical centers in the United States, yet I learned a great deal about these topics from the support group. I now share many of the things I learned from group members with my clinic patients.

The BrainTalk Communities epilepsy support group that we observed was facilitated by volunteer patient moderators, with little or no professional input. About 6% of the postings contained information that some of our medical reviewers considered at least partly mistaken, misinterpreted, outdated, or incomplete. We observed that other group members frequently corrected such misinformation. And group participants appeared to understand that they should not take uncorroborated statements as hard facts. They seemed well aware that some postings were erroneous, and in fact seemed to substantially overestimate the incidence of questionable materials.

I have also learned that an online group like the BrainTalk Communities epilepsy group is not only much smarter than any single patient, but is also smarter, or at least more comprehensive, than many physicians—even many medical specialists. While some postings do contain erroneous material, online groups of patients who share an illness engage in a continuous process of self-correction, challenging questionable statements and addressing misperceptions as they occur. And while no single resource, including physicians, should be considered the last word in medical knowledge, the consensus opinion arrived at by patient groups is usually quite excellent. And if more expert clinicians offered to consult informally with the online support groups devoted to their medical specialties—as I now do—we could help group members make information and opinion shared in these groups even better.

I had been taught to believe that patients could only be “empowered” by their clinicians. And while I do believe that clinicians can help in this regard by sharing their knowledge openly and by encouraging patient self-reliance, it now seems quite clear that growing numbers of patients are perfectly capable of empowering themselves, with or without their clinician's blessing. Physicians and other health professionals should do all they can to support them in this worthy effort.

Many patients are now ready, willing, and able to take a more active role in their own care, and the care of others with related diseases. By encouraging patients to do more for themselves and for each other, clinicians can help mitigate many of the negative effects of contemporary time-pressured medical practice. Thus, even though there may now be less time for the counseling, storytelling, support, information sharing, and empowerment-based training that was once a routine part of the typical office visit, we can now help our patients obtain such services by referring them to online patient networks.

The distributed expertise of online support groups is by no means limited to the emotional aspects of the illness and to the practical logistics of living with the disorder. It can also include current reviews of the literature, reports from the latest medical meetings, accounts of behind-the-scenes activities at the best treatment centers, sophisticated guidance on dealing with medical professionals, and excellent advice on dealing with complex aspects of medical management.

Finally, I have concluded that few, if any, physicians could have created a system like BrainTalk Communities. As a tech-savvy non-physician intimately familiar with both the inner workings of medical care and the power of information technology systems to create effective online communities, John Lester was less proprietary than most physicians are about medicine's proper professional “turf.” He was also less inhibited by professional biases regarding the potential value of the medical contributions that “unqualified” individuals might make. This is not an isolated occurrence. We suspect that the intensely professionally centered enculturation most physicians receive in their training and practice environments may render them, in the words of John Seely Brown and Paul Draguld, “blinkered if not blind” to the emergence of many promising new technocultural changes, which currently present new opportunities for health-care innovation [10]. Thus, physicians who seek to innovate in these areas might benefit greatly—as I have—from joining forces with Web developers, Net-savvy social scientists, experienced E-patients, and other colleagues unencumbered by the limiting belief systems that may result from our traditional medical training.
