Digital Health Communities: A Hidden Resource for Shared Healing (2021-2022)


Social media-based digital health communities (DHCs) play a significant yet poorly understood role in shaping the health experiences of numerous patients and caretakers. For example, an estimated 80,000 English-language Facebook groups focus on health topics. The groups range in size from three members to over 2.2 million. They include some of the oldest, most active and most established groups on the platform. 

Digital health communities on social media are changing people’s health outcomes. In many cases, they’re literally saving people’s lives. However, they’ve also created harm through misinformation. In both cases, it’s clear that the powerful new avenues of communication enabled by social media are having significant impacts on patient health and wellness.

Despite the prevalence and importance of these groups, physicians, journalists and academics appear to be mostly uninterested. With just one exception, the New York Times and Washington Post have not covered them. A PubMed search for the patient benefits of Facebook groups returns three relevant articles. None mention the kinds of significant benefits that have been identified and documented in initial research.

Project Description

Building on the work of last year’s project team, this team will research digital health communities across a variety of social media platforms to better understand their impacts on patient health. Using primary source materials as well as interviews with DHC community leaders and members, team members will identify examples of how community members and their loved ones are benefiting from and being harmed by the health information they’re able to find on social media.

Last year, the project team cataloged the scale and reach of DHCs on Facebook and began identifying communities with unique instances of supporting members in unusual and/or valuable ways. Examples of the kinds of communities the team catalogued include:

  • a community based around a disease that helped raise over $1 million for a child suffering from the disease;
  • a community for an orphan disease affecting 3 in 1,000,000 people that was able to convene a conference that brought together the leading experts in the field to push forward new research; and
  • a community that shares information about a rare and deadly disease so patients can share proper treatments with their physicians and better avoid potentially fatal outcomes.

This year, the team will continue to explore the 80,000+ DHCs on Facebook as well as begin to examine communities on additional platforms like Reddit, Twitter, Instagram, TikTok and YouTube.
