Abstract: Methods of crowdsourcing medical expert information are described. One such method includes receiving, from a first user during a first session over a network, a first query that includes a request for information regarding a patient condition, a therapy, and/or a medical test, and transmitting the query to a plurality of medical personnel. The first query further includes first session parameters selected by the first user from categories displayed by a processor to the first user. The method also includes receiving responses to the query from the plurality of medical personnel, and changing, based on the responses, an assigned probability of presenting to an index user, in response to a second query and during another session, at least one of a suggested diagnosis, a suggested therapy, a suggested inquiry to aid in establishing a diagnosis, a suggested medical test, a recommended source for further information, or a recommended medical professional.
