Cancer registration using case history database in hospital information system.

The World Health Organization (WHO) recommendations for hospital cancer registration, although being effective for combating the disease, need heavy manpower for complete implementation. A computer-based method for cancer registration is in use at Kyushu University Hospital as part of the integrated hospital information system. This method needs no manpower for data gathering, and the database includes almost all the core data and half of optional data recommended for cancer registration by the WHO. This database can, therefore, be regarded as a file for hospital cancer registration, and is used for two applications. The prepared form is automatically completed for the regional cancer register by a computer program without involving any physicians' time. In addition, a decision support system for the protocol used for a patient with a cancer was developed. Trendtables and graphs of clinical examination and medication are displayed, with suggestions and warning for physicians to help them make clinical decisions.
