Osteolink is building an online community for people with osteoporosis, their families, and physicians. It launched pilot programs in Sweden, Austria, and Germany to provide information sharing, offline and online connections, and ensure privacy. The site allows users to create profiles, participate in forums and blogs, find events, and view maps. Content was created and engagement strategies developed to educate users. Local osteoporosis groups helped spread awareness of the site. Initial results showed increased unique users and high site engagement across medical information and community features.
