Abstract: A medical interaction system is described that promotes connections of a medical nature between individuals, patients, doctors, nurses, therapists, and others. Users can share personal information with other users. Owners of personal information have complete control over what they share and with whom they share it by using built in access controls. The system provides search features so users can find other users who have common medical experiences, such as diagnosis, medication, health care provider, and therapist. Thus, the medical information system provides an environment for users to share medical experiences and connect with others in a way that reduces social isolation, increases experiential knowledge, and inspires confidence that others have successfully dealt with similar problems before.
