Abstract: An analysis system that analyzes an effect of a diagnosis and treatment action and measure is implemented by a computer including an arithmetic device configured to execute predetermined processing and a storage device connected to the arithmetic device. The analysis system includes: an input unit configured to receive an analysis condition; an event detection unit configured to extract a disease developing event; and a cost calculation unit configured to calculate a cost of a diagnosis and treatment action related to a disease name to be analyzed that is generated after a period of the disease developing event extracted by the event detection unit.

Abstract: Upon evaluation of a value of a diagnostic process, the value of a diagnostic process is evaluated not based on a simple cost but on a cost required for all processes of a patient who was in the diagnostic process through a follow-up survey. Diagnostic processes that are not relevant to a target diagnostic process are eliminated, clustering is performed on patients to divide the patients into clinically meaningful homogeneous groups, and the target diagnostic process is evaluated for each of the homogeneous groups. For the purpose, importance scores of data pieces of the clinical data are calculated and the relevant data is output using the output result of the medical knowledge extraction unit, clustering is performed on patients in the clinical data, and a clinical index and a cost are output for each of the clusters.
