US Patent 9946839 Search engine systems for matching medical providers and patients

In one embodiment, a 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 factors relevant to the base-concept such as readmission rate, infection rate, average length-of-stay, relative invasiveness, and healthcare facility ratings. The matching-engine system may send a search-results page to the user listing the recommended physicians.
