Sermo is an online community for physicians founded in 2006 by Daniel Palestrant. Open only to licensed M.D.s and D.O.s in the United States, Sermo is a place for physicians to post observations and questions about clinical issues and hear other doctors' opinions.


Sermo was originally imagined as an adverse effect reporting system. Reporting systems failed during Merck's 2004 Vioxx (Rofecoxib) recall, which removed Vioxx, a Cox-2 inhibitor, from the market due to an increased risk of myocardial infarction (heart attack). Palestrant believed that an online forum could collect and filter these types of observations more effectively than existing systems.[1] The site devloped into a discussion board covering a variety of non-clinical and clinical topics. The physician founders left in 2012 to start another business venture. Sermo was acquired by WorldOne, Inc. in July 2012 and rebranded to SERMO in 2014.[2]

SERMO has nearly 400,000 verified and licensed members;[3][4] it operates in the US, UK, Canada, Australia, South Africa, Ireland and New Zealand.[5]

SERMO enables medical crowdsourcing and knowledge sharing. In 2014, 3,500 patient cases were posted by doctors in the US. These cases were viewed 700,000 times and received 50,000 comments. Most patient cases get responses within 1.5 hours and are resolved within 24 hours.[6]

SERMO runs opinion polls twice a week to capture and report on the sentiment of physicians on current topics. These are often reported on in the press.[3][7][8]

Partnership with the AMA[edit]

In May 2007, Sermo announced a partnership with the American Medical Association.[9] The partnership gave doctors the ability to access AMA publications such as JAMA. In return, the AMA received limited access to read content on Sermo and create postings to which doctors can respond directly. This partnership ended in July 2009, amid virulent recriminations.[10]
