Abstract: Detailed resource information, including a resource preference indication, may be stored for a set of potentially available resource units. The system may store, for each resource unit, at least one performance metric score value. For each resource unit, a back-end application computer server may automatically access the performance metric score value in a resource performance metric computer store. Based on the at least one performance metric score value, the back-end application computer server may automatically update a state of the resource preference indication in an available resource computer store and automatically arrange to adjust at least one output parameter in accordance with the updated state of the resource preference indication. According to some embodiments, a diagnosis grouping platform groups similar claims handled by the panel of medical service providers, and a rating platform reviews performance of each medical service provider in the panel based on groups of similar claims.
