|Background of the establishment of medical integration database

After a hundred years of development, the hospital has accumulated a large number of clinical records, which carry the medical records of ancestors and colleagues, and are one of the precious assets of the hospital. With the popularity of electronic medical records and the rapid development of computer software and hardware, the ability to analyze large amounts of data has also made great progress. Therefore, the hospital started to build the "National Taiwan University Medical System Medical Integration Database" a few years ago. A research platform that meets the needs of users enables effective use of clinical data and various research applications. It is hoped that colleagues can use this platform to speed up research timelines and improve the quality of overall research in the hospital. Achieve the mission of developing prospective research.

National Taiwan University's medical system has nearly 3 million medical visits and 600,000 medical information each year. It has such a large amount of long-term hospital tracking data, including outpatient, inpatient, and emergency patients. The government also provides updated death registration files on a regular basis. In series, it can be used as a medical researcher in the hospital and a cross-institutional cooperation unit, using this huge medical information to conduct medical research, whether it is using traditional biostatistics methods, conducting generational or case-control studies, and can also be applied to artificial intelligence. The technology performs big data calculations. According to the three stages and five grades of the disease, risk factor search, inspection accuracy verification, treatment effect evaluation, and patient prognosis prediction can be carried out respectively. It is expected to achieve the goal of personalized precision medicine, thereby promoting medical progress and public health. However, if a single online system is used for daily medical practice and medical research, the collection and calculation of huge research data may affect the daily life of the hospital. The performance, flow, and data accuracy of operational information operations may have a negative impact on medical operations. Therefore, in the context of the vigorous development of information, medical care, and research in time and space, the National Taiwan University medical system began to plan for medical integration in 2013. Database (National Taiwan University Hospital-integrated Medical Database: NTUH-iMD), this unit is planned under the supervision of the Department of Medical Research, combined with professionals in clinical medicine, biostatistics, and information engineering, to integrate daily medical care. The database used (source database: SDB), transposed into a research database (research database: RDB), the transposition time began in 2006 and maintained a 2-year interval with the online database (SDB) to reduce online real-time changes impact and improve the stability of the data
