Clinical path establishing and optimizing method and system based on data mining and graph theory technology

The invention discloses a clinical path establishing and optimizing method and system based on data mining and a graph theory technology. The method includes the steps that S1, data are extracted for different diseases; S2, data in a distributed database are analyzed, and all diagnosis and treatment stage points of a complete treatment course are set for different diseases respectively; S3, based on the graph theory technology, the diagnosis and treatment stage points are stored and at least include diagnosis and treatment stages, information of treatment needing to be performed between the diagnosis and treatment stages and clinical pathology data included in each diagnosis and treatment stage; S4, by the utilization of the related algorithm of the graph theory, a typical path for the disease is searched for; S5, according to each diagnosis and treatment stage pint and the diagnosis and treatment activity of each diagnosis and treatment stage point, a clinical path is established and stored in a clinical path database; S6, the result and variation of applying the clinical path are recorded, and if variation exists, the clinical path is optimized again.
