In Japan, oversights of imaging or pathology examination results and diagnoses provided to patients have become a major problem because they affect patient prognosis. We have jointly developed and used the "Anti-Impact Information Leakage Prevention System (AiR)" since December 2019. This system works effectively because its introduction, which uses a data warehouse, has increased versatility and considerably improved the situation of confirmation and communication. We believe this system is working effectively.
