HOME＞Division of Scientific Data Registry : Biostatistics Section Aims of Study   In the Biostatistics section, computer databases are being established, and completion of domestic and international data linkage is planned. Therefore, we are contributing to laying the basis for epidemiological research in each department of the institute, and will provide the foundation for cooperative studies with domestic and foreign radiation injury researchers. Specific Projects   1. Establishment of computer databases Information on atomic bomb survivor living in Nagasaki (in 1968) was registered in computers. This consists mainly of the results of regular health examinations in approximately two million and six hundred thousand cases, cause of death in approximately 30,000 cases, and the results of investigations into the state of household re-establishment in approximately 50,000 cases. >> "Atomic Bomb Survior Database" page 2. Epidemiological research 1) Analysis of the causes of death and mortality rates among atomic bomb survivors 2) Assessment of the usefulness of regular medical examinations 3) Development of a screening method using the results of repeated medical examinations 4) Studies on health of the elderly 3. Application to health management The department developed a system whereby physicians can readily obtain past medical information and use this for health guidance, to show the results of repeated medical examinations, at the time of examination. 4. Information storage Since 1991, individual health files have been stored in a laser disk filing system. 5. International and domestic data linkage Background and Scope   We have collected medical and administrative data for atomic bomb survivors with the help of Nagasaki City Hall, Atomic Bomb Casualty Council, and other atomic bomb related organizations. This consists mainly of the results of regular health examinations and causes of death. These data are inputted and updated every month. The main results of the study of mortality are as follows: 1) The principal causes of death related to radiation exposure was cancer, 2) A periodic health examination performed at least once a year contributed to prolongation of life. The databases have facilitated not only the study of the late effects of the A-bomb but also studies on improving the health of A-bomb survivors. Doctors can retrieve physician's data on-line using a personal computer and the A-bomb survivors can see results of their health examinations. We will extend the A-bomb 'survivors' databases by international data linkage.
