Abstract: In one embodiment, a method comprises accessing a physician-referral-network, which comprises a number of nodes and a number of edges connecting the nodes, each of the edges representing a single degree of separation between the nodes. Each node represents a physician, and each edge represents a patient-referral between two physicians corresponding to the connected nodes. One or more references indicating a patient-referral from a first physician to a second physician is received. The physician-referral-network is updated based on the received reference. One or more performance-scores from the second physicians may be received, each performance-score corresponding to a patient-referral. A referral-score is calculated for the first physician based on the performance-scores. The method further comprises determining if a referral-score for a first physician is below a threshold referral-score.

Abstract: In one embodiment, a method comprises identifying one or more health-care-providers associated with one or more medical-specializations, wherein each medical-specialization is associated with a specialty class and at least one geographic area. A number of patient-diagnosis codes is received, each patient-diagnosis code corresponding to one of the health-care-providers and representing a patient-visit to the health-care-provider. The patient-diagnosis code includes at least one diagnosis within a condition-group for the patient visit, and a severity-factor for the diagnosis. The method further comprises determining all patient-diagnosis codes corresponding to the health-care-providers. A patient-volume is calculated for each health-care-provider, based on the patient-diagnosis codes and associated severity-factors. A variety-score is calculated for each health-care-provider based on the patient-diagnosis codes.

Abstract: In one embodiment, a method comprises receiving a set of parameters for selecting a physician from an administrator of a matching-engine system. The matching-engine system stores the parameters in a data store of the matching-engine system. The matching-engine system receives from a user a search query with a location of the user and a user-specified symptom or treatment. The matching-engine system determines a base-concept of a medical diagnosis or medical procedure based on the search query. The matching-engine system may identify a set of physicians to be recommended to the user based on the parameters, and a performance-score and experience-score associated with the base-concept for each physician. The matching-engine system may send a search-results page to the user listing the recommended physicians.

Abstract: In one embodiment, a method comprises receiving an indication of one or more care-episodes from a client device. Each care-episode may include an identifier for one or more physicians, a base-concept corresponding to a medical condition or medical treatment, one or more sub-concepts associated with the base-concept, and an indication of the resources used during the care-episode. The method comprises calculates one or more cost-factors for a base-concept for a particular physician based on the care-episodes associated with the base-concept. The method further comprises determining a specialty and geographic region of the particular physician. A peer group of physicians in the same specialty and geographic region is selected. A performance score is calculated based on the cost-factor for the physician compared to the cost-factors for the peer group of physicians.
