Social media is increasingly used in healthcare for customer service, community outreach, education, and public relations. Hospitals use platforms like YouTube and Twitter, but must consider HIPAA privacy laws and managing professional online identities. Patient support groups on Facebook have been created by some hospitals, including the University of Maryland Medical Center, to provide a restricted space for patients to connect over shared health topics and experiences in a moderated environment. These groups see varying levels of engagement from members discussing health issues and organizing offline meetups.
