The development of information and communication technology has led to the rapid growth of medical data encountered by various players in healthcare industry. This evolution from a paper-based database to electronic records demonstrates the continuous advancement of medical information systems. Medical institutions are paying more attention to this issue and attempting to figure out the applications of big data. However, most of them have struggled to find pathways to apply big data adequately. Using hybrid methodologies and examining Taiwan's healthcare industry, this research aims to assess, forecast and summarize the major applications of medical big data, and establish strategic pathways for medical institutions to follow regarding different dimensions of applications. First, a review of literature related to the utility of medical big data and interviews with relevant stakeholders were conducted. Content analysis was subsequently done to extract the key applications, and DEMATEL was used to find out their Net Relation Map (NRM). With the Innovation Importance-Resistance Analysis (IRA), this study carried out IRA-NRM analysis to cultivate the strategy of medical big data development. This research concluded a IRA-NRM framework of 4 application categories and 16 factors. Suggestions for medical institutions regarding the use of medical big data are also provided.
