Healthcare technologies have tended to focus on electronic health records and devices (e.g., devices within the home for patients or handheld devices for nurses and physicians), and the interaction between the two. However, no one to date has investigated how social networking technologies might be used to provide an assistive environment for patients who participate in group therapy. In this paper we propose such an environment and go on to discuss the privacy requirements and security implications in developing an appropriate support mechanism.
