Despite national debate on whether doctors should use social media, some physicians are forging ahead, using platforms such as Twitter to interact with colleagues, expand their knowledge and even connect with patients. Dr. Nick Bennett, the infectious disease and immunology medical director for Connecticut Children’s Medical Center in Hartford, said he benefits professionally from Twitter. He created his account, @peds_id_doc, a few years ago to see what Twitter was about, and he’s remained a loyal user. Bennett started by following health-related accounts and live tweeting from conferences. He also joined Twitter chats – conversations that use hash tags to link tweets.
