title: On experiences of i2b2 (Informatics for integrating biology and the bedside) database with Japanese clinical patients' data.
abstract: Informatics for Integrating Biology and the Bedside (i2b2) is a database system to facilitate sharing and reuse of clinical patients' data collected in individual hospitals. The i2b2 provides an ontology based object-oriented database system with highly simple and flexible database schema which enables us to integrate clinical patients' data from different laboratories and different hospitals. 392 patients' data including carcinoma and non-carcinoma specimens from cancer patients are transported from the Integrated Clinical Omics Database (iCOD) to the i2b2 database for a feasibility study to check applicability of i2b2 ontology and database schema on Japanese clinical patients' data. No modification is required for the i2b2 data model to deal with Japanese characters. Some modification of ontology is required to integrate biomedical information extracted from the cancer patients' data. We believe that the i2b2 system will be practical infrastructure to integrate Japanese clinical databases if appropriate disease ontology for Japanese patients is provided.
