Nowadays, a vast amount of data is stored in hospital information systems with daily medical practices. However, utilization of such data is limited to the direct medical care for patients themselves. The indirect usage for medical studies is still not so active. We have shown various examples of the effective data analysis using accumulated medical data in a hospital information system. In particular, Effective calibration method for laboratory test data for long time period, Comprehensive analysis of the diagnostic characteristic pattern for laboratory test data, Diagnostic characteristics for CBC cell distribution data, Prediction by pattern extraction with artificial intelligence from laboratory-test time series data are shown to be useful.
