Twitter-HashtagsAs the Free Open Access Meducation (FOAM; #FOAMed) movement has continued to flourish over the past few years, Twitter has become a vital method for disseminating/discussing educational and clinical content. We thought it would be interesting to see who is being ‘followed’ on Twitter in the FOAM world. Certainly, the metric of Twitter followers does not necessarily correlate with quality. And, it misses newcomers to the FOAM scene and those with a more focused area of expertise/interest. We are more interested in understanding the landscape such as who is involved, geographic locations, areas of expertise, and association with blogs/podcasts.

Our search strategy was simple:

  1. Twitter was searched for all users with #FOAMed, #FOAMcc, #FOAMtox, #FOAMped, #FOAMems, and/or #FOAM in his/her Twitter profile. *
  2. This was cross-referenced with Dr. Mike Cadogan’s (@sandnsurf) FOAMed Twitter list (782 members as of July 11, 2014).

* Those without one of the FOAM hashtags in his/her Twitter profile are not included on this list, even if they produce excellent, free content (eg, Dr. Amal Mattu, @amalmattu).

  • Not too surprisingly, the father of FOAMed, Dr. Mike Cadogan, leads the way followed closely by Dr. Scott Weingart.
  • This list, although only a small subset, seems to be a microcosm of the larger FOAM community.
    • Worldwide representation from Australia to the UK to the USA.
    • A variety of healthcare professional representation including physicians, nurses, pharmacists, and EMS providers.
    • Subspecialties within Emergency Medicine are also well represented including critical care, ECG, medical education, pharmacy, radiology, toxicology, and ultrasound.
