Introduction

 The Division of Medical Informatics was established on February 1, 2018, to manage the hospital information system and the network of the National Cancer Center Hospital (NCCH).

The Team and What We Do

 The roles of the Division of Medical Informatics include managing the hospital information systems and infrastructure of the National Cancer Center Hospital and contributing to medicine and cancer research by providing a secure, efficient and advanced information systems environment.

Research activities

 Through the following projects, we proposed information systems that promote the use of clinical data and the establishment of a data utilization infrastructure in the hospital.

• A database system for in-hospital clinical information data scrutiny was established to establish a quality assurance mechanism for medical information data in the hospital information system ("Efforts to Create Real World Evidence", FY2019- AMED Medical Technology Implementation Promotion Project).
• A structured data collection infrastructure to promote oncology research was developed in the central hospital as a vendor neutral archive (VNA) for clinical research (CREST / PRISM).
• A prototype of the Universal Viewer was developed, which enables us to display clinical information in an adequate format according to disease scenarios and scenes.
• Research has been conducted concerning methodologies to use real-world data with hospital information systems, referring to overseas cases.

Education

 We are working to develop staff who can operate and manage the entire information system so that we can provide the information necessary for medical care and research activities. We are also engaged in information literacy education for the entire NCC through orientation for new employees and support activities for research projects.

Future Prospects

 As part of the renewal of the hospital information systems started in May, 2021, we are planning to develop an environment that can provide the clinical data necessary for medical care and research in a timely and appropriate manner. We will continue to develop advanced hospital information systems to lead medical care and research in Japan and overseas.
